Symposium continued: Tack operation for idiopathic endolymphatic hydrops: An update
Authors: Cody D. Thane R. , Mcdonald Thomas J. 
Published: October 2006

AbstractThis paper discusses an analysis of two groups of patients who underwent a tack operation for incapacitating recurrent attacks of vertigo due to idiopathic endolymphatic hydrops. Group I consisted of the first 140 patients operated on by one of the authors (D.T.R.C.). All were followed up for at least 5 years after the operation. However, between the 63rd and 166th postoperative months, 12 patients died of unrelated causes, and an additional 26 patients were lost to follow‐up between the 70th and 119th postoperative months. The analysis was based on the condition of these patients up to the time of their death or the time that they were last contacted. The mean postoperative follow‐up for the 140 patients was 12 years 9 months, and the range was 63 to 197 months.Group II consisted of 150 consecutive patients who had a tack operation performed by several consultants and residents in the Department of Otorhinolaryngology at the Mayo Clinic, and the opportunity for follow‐up of at least 5 years existed for all patients. The patients who were lost to follow‐up in the first 56 postoperative months were excluded from the analysis unless at the time they were last seen the operation had not controlled their vertigo, in which case the results were classified as failures. On this basis, 22 patients (15%) were excluded from the study, so that 128 patients remained in the analysis. The mean postoperative follow‐up for this group was 9 years 4 months, with a range of 56 to 182 months.The following conclusions were reached. Vertigo was satisfactorily controlled in 79% of the patients in the two groups. Hearing was improved or maintained in 66% of the patients in Group I and 60% of the patients in Group II. A moderate‐to‐profound sensorineural hearing loss occurred in 34% of the patients in Group I and 40% of the patients in Group II. We consider the tack operation the conservative operation of choice in the management of idiopathic endolymphatic hydrops.
A ten year statistical follow‐up of 245 consecutive cases of endolymphatic shunt and decompression with 328 consecutive cases of labyrinthectomy
Authors: Brown James S. 
Published: October 2006

AbstractThe etiology of Meniere's disease is unknown and the treatment is empirical and at best controversial. The goals of treatment are hearing preservation and the control of vertigo. Between 1956 and 1971, a total of 5,208 cases of Meniere's disease was seen. Medical treatment was effective in 4,530 cases (87%), while surgery was employed in 677 cases (13%).The surgical procedures were divided into 1. a conservative group where useful hearing was still present and 2. a destructive group where no useful hearing existed.The conservation operation employed was a procedure on the endolymphatic sac, while the destructive procedure was a labyrinthectomy. In a small series of cases where these procedures failed to control the vertigo, a middle cranial fossa vestibular nerve section was done.This review of our experience summarizes the efficacy of each procedure in reaching the stated goals of hearing preservation and the control of vertigo.
Surgical management of vestibular meniere's disease with endolymphatic mastoid shunt
Authors: Miller Gale W. , Welsh Randall L. 
Published: October 2006

AbstractThe early stages of Meniere's disease may consist only of vestibular symptoms. These patients with vertigo alone may be incapacitated by this condition. A great many of these patients are unresponsive to medical therapy and tend to progress to cochleovestibular disease. Early surgery on such individuals may decrease vertigo and give the added benefit of preserving hearingThis paper reports the results of endolymphatic mastoid shunts performed on 24 patients with normal hearing who had medically uncontrolled vestibular Meniere's disease. The patients underwent surgery between 1978 and 1981, and each has been followed for at least 1 year. Vertigo was decreased or abolished in 21 of 24 patients (87%). Hearing remained unchanged in 19 of the 24 patients (79%) and was mildly impaired postoperatively in 4 (16.7%). Only 1 patient had moderate postoperative hearing loss. Of the 5 patients with reduced hearing, 4 had improvement of vertigo. There were no cases of surgically‐induced deafness.
Oncogenes: Preliminary studies in head and neck cancer
Authors: Friedman William H. , Rosenblum Barry , Loewenstein Paul , Thornton Helen , Katsantonis George , Green Maurice 
Published: October 2006

AbstractDNA has been extracted from squamous cell carcinomas of the larynx, base of tongue, and nasopharynx. These tumors were excised from patients at the St. Louis University Medical Center and processed at the Institute for Molecular Virology of the St. Louis University Medical Center. NIH/3T3 cells were transfected with the DNAs from these cancers. Malignant, transformed foci of NIH/3T3 cells have been observed. These foci have been cloned and grown in quantity. The cloned foci have been injected into nude mice with the production of highly malignant sarcomas. DNA extracted from these sarcomas has shown homology with human DNA on hybridization analyses of both nasopharynx and tongue cancer. Further hybridization studies are being conducted on the larynx cancer‐induced sarcomas and on the DNAs taken from the original transformed foci of NIH/3T3 cells transfected with squamous cell cancers of the larynx, nasopharynx, and tongue base. Our preliminary results indicating the presence of human sequences in the mouse sarcomas support the hypothesis that human cellular transforming gene(s) may be present in the DNA isolated from the head and neck cancers. Additional studies will include repetitive retransfection of NIH/3T3 cells, molecular cloning of putative oncogenes, and DNA sequence analysis of the cloned oncogenes. It is hoped that identification of putative oncogene sequences will result in the identification of the proteins coded for by the specific nucleotide sequences responsible for malignant cellular transformation by DNA extracted from head and neck tumors.
Management of aneurysms of the petrous portion of the internal carotid artery by resection and primary anastomosis
Authors: Glassock Michael E. , Smith Peter G. , Bond Arthur G. , Whitaker Samuel R. , Bartels Loren J. 
Published: October 2006

AbstractIntrapetrosal internal carotid artery aneurysms are distinctly uncommon lesions which are difficult to diagnose and treat. With the evolution of the infratemporal fossa approach, direct surgical management of these aneurysms is possible. Application of this technique is detailed in a case report. A discussion of alternate therapeutic modalities and a review of aneurysmal pathophysiology and diagnosis are included.
Sleep apnea following bilateral excision of carotid body tumors
Authors: Zikk Daniel , Shanon Eliahu , Rapoport Yoram , Samuel Joram 
Published: October 2006

AbstractA patient is described who developed apnea, hypertention, and tachycardia following the excision of bilateral carotid body tumors. Hypertension and tachycardia resulted, most probably, from bilateral ablation of the carotid sinus and/or the nerve of Hering. These phenomena have been described in the literature. The pathogenesis of the apneic attacks may be related to the ablation of the peripheral sensory organs (both carotid bodies), interference with the function of the respiratory automatic control system, and impaired control of ventilation during non‐REM sleep. Temporary unilateral paralysis of the hypoglossal nerve with partial airway obstruction possibly represented a mechanical trigger. The apneic attacks subsided but bouts of hypertention and tachycardia persist.
Reliability of frozen section diagnosis in head and neck neoplasms
Authors: Remsen Kenneth A. , Lucente Frank E. , Biller Hugh F. 
Published: October 2006

AbstractTo evaluate the reliability of frozen section diagnosis we reviewed a series of 1146 consecutive frozen sections performed during a 5‐year period. The frozen section diagnosis was then compared to that found on paraffin section and the results categorized into 12 regions in the head and neck.We found an overall reliability of 96%. The total percentage of false positive and false negative results were 0.35% and 3% respectively. Frozen section diagnosis was most accurate on the submandibular gland (no errors), nose and paranasal sinuses (no error), followed by the thyroid gland (0.8% error). Areas in which frozen section diagnoses were least accurate included the nasopharynx (12.5% error) and the oropharynx (8.7% error). We conclude that frozen section diagnosis is highly accurate in most regions of the head and neck.
Epidermoid cyst of the frontal bone masquerading as frontal sinusitis
Authors: Abedi Esrafil , Frable Mary Ann 
Published: October 2006

AbstractEpidermoid cysts occur whenever two epidermal surfaces fuse together during early intrauterine life and an ectodermal implant is retained deep to the surface. They are very slow growing and symptoms may not occur till middle age. The authors present a patient whose symptoms of frontal headache were mistaken for frontal sinusitis for over 10 years. The patient's symptoms were completely relieved by surgical excision of an epidermoid cyst of the frontal bone.
Bone conduction evaluation related to mastoid surgery
Authors: Hornung Shmuel , Ostfeld Ervin 
Published: October 2006

AbstractThe bone conduction threshold changes of 97 patients (100 ears) who underwent mastoid surgery were determined by comparing the last preoperative audiogram with the 1 year postoperative audiogram. Three types of mastoid surgery were evaluated: Radical mastoidectomy, modified radical mastoidectomy, and intact wall atticomastoidectomy. The average three speech frequency preoperative bone conduction threshold was 17.4 dB (S.D. 11.5) in the radical mastoidectomy group, 10.1 dB (S.D. 9.6) in the modified radical mastoidectomy group, and 10.7 dB (S.D. 8) in the intact wall atticomastoidectomy group.The difference between the average three speech frequency preoperative bone conduction threshold of the radical mastoidectomy group differed significantly when compared to the modified radical mastoidectomy or intact wall atticomastoidectomy group.The postoperative average three speech frequency bone conduction threshold did not change significantly following the three surgical procedures evaluated.

AbstractChondrosarcoma of the nasal septum is an uncommon lesion. Review of the English literature reveals only 14 cases. This paper reports an additional case observed in a Japanese series of seven cases. The clinical features are reviewed, and a most effective treatment with minimum side effects is organized by an interdisciplinary group of specialists in surgery, radiotherapy and regional chemotherapy.
Mandibular lingual releasing approach to oral and oropharyngeal carcinomas
Authors: Stanley Robert B. 
Published: October 2006

AbstractResection of a carcinoma of the oral cavity or oropharynx requires adequate exposure for direct visual and bimanual examination. Transoral resection of tumors of the oral cavity using the “pull‐through” procedure can be difficult due to interference by the circumoral tissue and mandibular arch. Exposure of carcinomas involving the base of tongue may require mandibulotomy or lateral mandibulectomy even when margin control does not mandate removal of the jaw. Alternatively, surgical techniques routinely used for exodontia and periodontal surgery can be applied to the creation of a mandibular lingual mucoperiosteal flap that allows for the entire tongue and floor of mouth to be delivered into the neck. Oral cavity and base of tongue lesions can then be resected with excellent direct visual and palpable control of margins, but without lip splitting, mandibulotomy or mandibulectomy.
Extended single transverse neck incision for composite resections: An update of technique and results
Authors: Becker Gary D. 
Published: October 2006

AbstractA composite resection for carcinoma of the upper aerodigestive tract was performed on 42 patients using a single transverse neck incision for the neck dissection, and an extension of this incision for inclusion of the primary lesion. This incision satisfies all the criteria that should be considered when designing a flap. Surgical exposure was adequate, no skin necrosis occurred, compatibility with reconstructive procedures was excellent, and resultant cosmetic deformity was minimal.
Laryngeal carcinoma — or is it laryngeal blastomycosis?
Authors: Payne James , Koopmann Charles F. 
Published: October 2006

AbstractA patient is described who was evaluated for persistent hoarseness. Although an initial diagnosis of squamous cell carcinoma of the larynx was made, review of the pathology slides revealed pseudoepitheliomatous hyperplasia, acanthosis, and what appeared to be a fungal infection. After a detailed work‐up was initiated the patient was treated successfully with ketoconazole for a blastomycosis infection of the larynx. The literature relative to blastomycosis infections of the respiratory larynx is reviewed. The authors emphasize that patients who show evidence of acanthosis and pseudoepitheliomatous hyperplasia along with the diagnosis of squamous cell carcinoma should be suspected as having a potential fungal infection.
Head and neck presentations of acquired immunodeficiency syndrome
Authors: Rosenberg Richard A. , Schneider Kenneth L. , Cohen Noel L. 
Published: October 2006

AbstractSince December 1980, over 2,000 cases of acquired immunodeficiency syndrome (AIDS) have been reported. The charts of 72 patients admitted to the New York University Medical Center with a diagnosis of AIDS were reviewed with particular emphasis on presenting signs, symptoms and laboratory values. Symptoms tended to be non‐specific and most often resembled an upper respiratory infection. Over 95% of the patients presented with either diffuse adenopathy, oral or facial lesions consistent with Kaposi's sarcoma, white oral lesions, or anergy. Laboratory findings included leukopenia, increased erythrocyte sedimentation rate, thrombocytopenia and anemia. The in‐hospital mortality rate was 26%.The current status of our knowledge concerning AIDS is reviewed and discussed. The frequency and types of presenting signs and symptoms in the head and neck are reported in order to alert the otolaryngologic community to this entity.
Reconstruction of the hypopharynx following extensive loss of mucosa
Authors: Sambataro G. , Oldini C. , Mazzola R. F. 
Published: October 2006

AbstractMucosal loss of the hypopharynx, following pharyngostome or wide resection of carcinoma, poses problems for repair. The authors emphasize a reconstructive procedure based on the use of three elements combined together in various ways: residual strip of mucosa of the posterior pharyngeal wall, a musculomucosal pedicled flap obtained from the base of the tongue, a pectoralis major musculocutaneous flap. Thus any defect of the hypopharynx can be repaired in one stage. The safety of the procedure is well tested with good clinical results and lack of complications.
Velo‐pharyngo‐laryngeal myoclonus: Evaluation of objective tinnitus and extrathoracic airway obstruction
Authors: Toland A. Daniel , Porubsky Edward S. , Coker Newton J. , Adams H. Gregory 
Published: October 2006

AbstractVelo‐pharyngo‐laryngeal myoclonus, the rapid, rhythmic contraction of muscles of the pharynx and larynx, is a rare neurological manifestation of numerous disease processes affecting the cerebellum.In its most common form, palatal myoclonus, this disease frequently presents to the otolaryngologist as objective tinnitus. Impedance audiometry provides a useful means of verifying suspected palatal myoclonic activity through recorded changes in the middle ear pressure, as mediated by muscle activity at the proximal portion of the eustachian tube.A very rare case of velo‐pharyngo‐laryngeal myoclonic with clonic contraction of the laryngeal adductors and subsequent extrathoracic airway obstruction is presented. Tracheostomy provided immediate symptomatic relief of dyspnea.
Chondrosarcoma of the head and neck
Authors: Finn Douglas G. , Goepfert Helmuth , Batsakis John G. 
Published: October 2006

AbstractA review of 23 cases of chondrosarcoma of the head and neck is presented. The sites of involvement include the gnathic bones, paranasal sinuses and orbit, nasopharynx, base of skull, larynx and the cervical spine. Histologic grading of the neoplasms into I, II, and III, primarily dependent on deviation from phenotypic cartilage and mitoses, afforded excellent correlation with prognosis and survival. While increasing size of the chondrosarcoma is not always associated with higher grade tumors, rapidly growing and extensive neoplasms are usually grade II or III chondrosarcoma.
Mechanisms of nasal obstruction in sleep
Authors: Cole Philip , Haight James S. J. 
Published: October 2006

AbstractPathophysiological aspects of the nasal and pharyngeal airways are discussed with particular reference to breathing disorders in sleep. Hypotonus of dilator muscles in sleep permits the pharynx to comply with inspiratory pressures. If airflow resistances are increased by nasal disease, complete inspiratory obstructive closure of the pharynx and apnea can result from nasal breathing in sleeping subjects. Recumbency increases resistive swelling of inflamed nasal mucosa. Furthermore in patients with normal mucosa and unilateral nasal obstruction, contralateral recumbency induces contralateral obstruction which increases resistance to nasal breathing; and in either dorsal or lateral recumbency the congestive phase of the spontaneous nasal cycle acts in a similar way. Examples of breathing disorders in sleep and impaired quality of sleep in patients with obstructive mucosal disease and both bilateral and unilateral structural abnormalities arc cited.
Laryngospasm induced pulmonary edema
Authors: Mcgonagle Martin , Kennedy Thomas L. 
Published: October 2006

AbstractTwo case reports of laryngospasm‐induced pulmonary edema following general anesthesia are presented. Therapy consisted of immediate reintubation, application of positive pressure ventilation, and diuresis. This phenomenon should be recognized rapidly with appropriate therapy instituted immediately to avoid other complications. Preventive measures are discussed and a modified protocol of the management is outlined.
Degloving approach for total excision of inverted papilloma
Authors: Sachs Michael E. , Conley John , Blaugrund Stanley , Rabuzzi Daniel D. , Price John 
Published: October 2006

AbstractInverted papilloma, because of its insidious and aggressive clinical course, must be completely excised. Previously, the customary procedure advocated for this goal was a lateral rhinotomy. The degloving approach, which consists of lifting the soft tissues from the mid portion of the face, thereby furnishing unlimited exposure to the pyriform fossae and the lateral nasal walls, offers an excellent alternative to the lateral rhinotomy technique.The degloving procedure involves no external scarring and improves the visibility of the total operative field. En bloc dissection of the lateral nasal wall is then accomplished and extended to include a sphenoethmoidectomy or partial excision of the medial orbital wall, as dictated by the extent of disease.The procedure has been performed by the authors in 46 cases, and has proved to be an extremely valuable technique, displaying excellent cosmetic and functional results with minimal complications.
Central presbycusis
Authors: Welsh Louis W. , Welsh John J. , Healy Michael P. 
Published: October 2006

AbstractThe phenomenon of central presbycusis has been investigated employing a central auditory battery in elderly individuals with essentially normul hearing. The studies indicate a progressive loss in central auditory competence measured by simultaneous binaural challenges and frequency and temporal distortion tests. The rate of failure is related to age, on the whole, but there is increasing variability from the normals with seniority. The hearing disability in noise or speech competitive environments is explained by these data. Auditory disabilities related to poor articulation and rapid speech presentation are identified by other tests in the battery. Central presbycusis, in addition to the peripheral form, does exist and further compounds the hearing disorder in many elderly.
Tape attachment therapy for correction of congenital malformations of the auricle: Clinical and experimental studies
Authors: Muraoka Michinari , Nakai Yoshiaki , Sasaki Takaharu , Ohashi Yoshihiro , Maruoka Kenichi , Furukawa Masayoshi 
Published: October 2006

AbstractAfter the auricular cartilage of 5‐week‐old rabbits was bent and fixed by suture, the cartilage increased in thickness in a short period of time. The thickness was maximal 6 weeks later and slightly greater than that of the control cartilage 12 weeks later. At this stage, the auricle was fixed in curved form. There was no difference in the morphology of cartilage cells between the bent group and the control.Tape attachment therapy is very simple. We propose that surgical treatment should be designed after a few months of tape attachment therapy.In the present work, the effect of taping was graded good in 4 cases of Stahl ear, 1 case of atypical cryptotia, and 2 other cases. In 2 cases of cup ear the result was fair, but this deformity with marked auricular aplasia was not curable by this conservative treatment.
Conservation surgery for cancer of the larynx in the elderly‐
Authors: Alajmo Ettore , Fini‐Storchi Omero , Agostini Vittorugo , Polli Gianni 
Published: October 2006

AbstractThe postoperative course was evaluated for 458 consecutive patients, all over the age of 56 years, who had undergone laryngeal conservation surgery in the last 10 years. One hundred seventy‐one patients aged 66 and over made up the “elderly” group and 287 patients, aged between 56 and 65 years formed the control group.It was confirmed that cordectomy and frontolateral laryngectomy are feasible even in elderly patients. Bronchopneumonia is the most frequent and serious complication after supraglottic laryngectomy. Therefore this operation should be performed in the elderly patient only after a thorough evaluation of cardiac and respiratory function. Prophylactic neck dissection should not be done for No necks and the second therapeutic neck dissection in N2 cancers should be staged 6 or more weeks later. Hemilaryngopharyngectomy and subtotal reconstructive laryngectomy with cricohyoidpexis are not advisable in elderly patients.
Intramuscular hemangioma of the head and neck
Authors: Wolf Gregory T. , Daniel Fred , Krause Charles J. , Kaufman Roger S. 
Published: October 2006

AbstractIntramuscular hemangiomns are unusual tumors in the head and neck region that occur most frequently in the masseter muscle and are often confused with parotid neoplasms. Four cases are described and the literature reviewed. The diagnosis and management of these tumors are discussed in view of the fact that accurate preoperative diagnosis is unusual and tumor recurrence rates high. Increased awareness of the clinical presentation of intramuscular hemangiomas should enhance diagnostic accuracy and facilitate optimal treatment planning.
