Olfactory neuroblastoma: Presentation of a case and review of the japanese literature
Authors: Tamada Akira , Makimoto Kazuo , Okawa Masanao , Hirono Yoshinobu , Yamabe Hirohiko 
Published: October 2006

AbstractOlfactory neuroblastoma is an uncommon malignant tumor arising from the nasal cavity. During the past 18 years from 1964 to 1982, only 24 cases have been in Japanese literature, including this case. The average age of these patients is 42.3 years, ranging from 4 to 75 years old. The sex ratio of male to female is 10:14, female being prevalent moderately. The peak distribution is from 30 to 40 years old. The majority of the patients died of distant metastasis within 2 years of diagnosis. Therefore, the overall prognosis in Japan is very poor, as compared with about a 50% 5 year survival rate in the western countries. This is probably because this tumor is difficult to diagnose correctly, and the chance to start treatment early is apt to be missed here, though some tumors behaved very aggressively from the beginning, metastasizing early.
Roentgenographic diagnosis of acoustic neurinoma
Authors: Harner Stephen G. , Reese David F. 
Published: October 2006

AbstractThis article reviews the roentgenographic studies performed in 131 patients who had surgically confirmed acoustic neurinomas. In this 5‐year study (1978‐1982), all patients had computed tomography (CT) and 82% had petrous apex tomography. Approximately 18% of patients underwent angiography, and 18% had positive contrast rhombencephalography. The diagnostic capability with CT scanning has improved remarkably. There were no false‐negative results for scans obtained in 1981 and 1982. At the same time the accuracy of other radiographic and audiometric tests was decreasing. The proportion of small tumors diagnosed has increased 200%, with a corresponding decrease in medium and large tumors. Tumors can be diagnosed at an earlier stage; and, because of this, surgical results have improved. No surgical mortality occurred in this series, preservation of the facial nerve was excellent, and in some patients cochlear function was maintained
Ear disease and hearing loss among navajo children – a mass survey
Authors: Nelson Scott M. , Berry Robert I. 
Published: October 2006

AbstractA team of trained technicians in a specially equipped mobile van conducted a mass screening effort on the Navajo Reservation from 1978 to 1980 to detect and refer individuals with ear disease and hearing loss; 15,890 school children were examined. The prevalence data and correlations of hearing level with ear disease are presented: 4.0% of the children had TM perforations, 2.3% middle ear effusions, 1.9% TM atelectasis, and 0.4% had sensorineural hearing loss. Microtia was found in 1:935, with a cluster on the Western one‐fourth of the reservation. Cholesteatoma was rare. The patterns of ear disease are contrasted with other groups.
Infectious diseases of the sphenoid sinus
Authors: Holt G. Richard , Standefer John A. , Brown Willis E. , Gates George A. 
Published: October 2006

AbstractThirty‐one patients with sphenoid sinusitis were treated from 1978‐1982. Twenty patients had infections contiguous with other paranasal sinus disease. Five of these patients had fungal sinusitis. Eleven patients were seen with isolated sphenoid sinusitis; 3 were secondary to trauma and 8 were due to nontraumatic causes. Possible etiologies include upper respiratory infections, developmental abnormalities, and water forced into the nasal cavity during swimming. The immunocompromised patient is more likely to present with minimal symptoms with a fungal infection, and aggressive diagnostic and therapeutic measures should be undertaken. Because the symptoms of headache, nasal stuffiness, proptosis, ptosis and decreased visual acuity may be interpreted as an intracranial, neurological, or vascular problem, a misdiagnosis may be made. A high index of suspicion for sphenoiditis should be maintained. Therapy involves a combination of medical (antimicrobial agent) and surgical (sinus drainage and marsupialization) management.
Hazards encountered in management of basal cell carcinomas of the midface
Authors: Stanley Robert B. , Burres Steven A. , Jacobs John R. , Mathog Robert H. 
Published: October 2006

AbstractBasal cell carcinomas often exhibit aggressive and destructive behavior on the midface, with invasion into the orbit, paranasal sinuses, and even the frontal fossa. Minor modifications in surgical procedures for cosmetic considerations may have devastating consequences on the patient's survival. Tumor extirpation should not be compromised by preoperative planning of the method of reconstruction to be used. Margin control intraoperatively with either conventional frozen sections or the fresh tissue Mohs technique is mandatory for success. If any margin is questionable, reconstruction should be delayed at least until permanent sections confirm complete tumor removal. Ten cases are presented and the literature reviewed to emphasize that inadequate initial management probably contributes more to the observed destructiveness of these lesions than histologic aggressiveness or embryologic patterns of the midface.
Head and neck manifestation of histiocytosis‐x
Authors: H. Smith Richard J. , G. Evans John N. 
Published: October 2006

AbstractHistiocytosis‐X is an uncommon disease, but is relevant to the otolaryngologist because patients with this malady present with, or ultimately develop, head and neck manifestations. Sixty‐two patients with histologically confirmed histiocytosis‐X have been examined at the Hospital for Sick Children in London since 1958. Most patients were under 2 years of age on initial examination and had either osseous or dermatologic disease involvement. Less commonly, otic or oral lesions were found.Histiocytosis‐X is a systemic disease and must be treated accordingly. Isolated lesions may mimic common disease processes, therefore it is imperative that if a seemingly simple problem does not resolve with routine therapy, further patient evaluation be undertaken, If diagnosed, histiocytosis‐X can generally be controlled with Steroid therapy, or in more recalcitrant cases, by the addition of chemotherapy.
Absent auditory brain stem response: Peripheral hearing loss or brain stem dysfunction?
Authors: Kraus Nina , Özdamar Özcan , Stein Laszlo , Reed Nancy 
Published: October 2006

AbstractInterpretation of auditory brain stem response (ABR) findings can be problematic in cases where waves III and V are absent. Such findings can be attributed to profound hearing loss, brain stem neuropathology, or both. Over a 3‐year period, 48 patients with no known brain stem damage and on whom audiologic data were available were found to have no response by ABR or absent waves III and V. Severe to profound hearing loss was documented in 38 cases, audiometric data were equivocal in 3 cases, and 7 patients showed pure tone sensitivity ranging from normal hearing to moderate impairment. Thus 15% had better hearing sensitivity than might have been expected from their ABR findings. Each of these patients also exhibited abnormal acoustic reflex findings. We report the electrophysiological (ABR, MLR, acoustic reflex}, medical (history, neurological, EEG, CT scan) and behavioral (audiometric, speech and language, learning disabilities, psychological) data which characterize this group of patients.
Intraoral ligation of the maxillary artery for posterior epistaxis
Authors: Maceri Dennis R. , Makielski Kathleen H. 
Published: October 2006

AbstractIntraoral ligation of the maxillary artery for intractable posterior epistaxis has been used effectively in 14 consecutive patients, all of whom had failed conventional anterior and posterior packing techniques. Fresh cadaver material was dissected in order to define the anatomic relationships of the infratemporal portion of the maxillary artery, as well as to develop the surgical technique prior to clinical application. The results indicate that this technique is rapid, safe, versatile, and effective in the majority of patients that require surgical interruption of the blood supply to the nose. The results of this study and the surgical technique are discussed.
Computed tomography in suppurative ear disease: A correlation of surgical and radiographic findings
Authors: Jackler Robert K. , Dillon William P. , Schindler Robert A. 
Published: October 2006

AbstractForty‐two patients with chronic otitis media underwent preoperative CT scanning followed by surgical exploration of the middle ear and mastoid. The CT finding of abnormal soft tissue density associated with bone erosion was highly correlated with the surgical finding of cholesteatoma. By contrast, the total absence of abnormal soft tissue on CT essentially excluded cholesteatoma. However, 50% of all patients had abnormal soft tissue on CT scan not accompanied by bone erosion. In this largest group of patients it was not possible to diagnose or exclude cholesteatoma on the basis of CT findings alone. Also, CT occasionally gave the erroneous impression of lateral semicircular canal fistulization, tegmen tympani erosion, and facial nerve involvement due to volume averaging of these structures with adjacent soft tissues. CT scan has a role in the evaluation of selected patients with chronic otitis media, but must be interpreted cautiously in view of its limitations and numerous pitfalls.
Practical versus theoretical management of autoimmune inner ear disease
Authors: Hughes Gordon B. , Kinney Sam E. , Barna Barbara P. , Calabrese Leonard H. 
Published: October 2006

AbstractAutoimmune inner ear disease is an uncommon but distinct clinical entity. Our ignorance of the immune mediating pathways, need of further animal model experimentation, variability of laboratory test results and of patient treatment responses illustrate how poorly we understand this disorder. The purpose of this review is to compare practical vs. theoretical management of autoimmune inner ear disease, based upon our current knowledge of the disease process and upon a review of clinical experience at the Cleveland Clinic Foundation. Representative case histories are presented. The following preliminary conclusions are discussed:
After early identification – What follows? a study of some aspects of deaf education from an otolaryngological viewpoint
Authors: Stewart Irwin F. 
Published: October 2006

AbstractOtolaryngologists hove accepted their role in the early diagnosis of the deaf and hard of hearing child; however, the social implications and habilitative programs embarked upon may often be regarded as unrelated to the practice of otolaryngology. The otolaryngologist is a key member of the team responsible for early detection and diagnosis, and he must become as involved with the available educational programs as are the other highly qualified competent individuals bringing expertise to the problem. The reason for emphasizing this area is that the otolaryngologist has witnessed a number of major expansions in knowledge which have occurred in the past 15 years. These include: 1. Early identification of deafness through screening programs. 2. Early diagnosis through peripheral and brain stem evoked response audiometry. 3. Improvement in amplification in hearing aids. 4. Earlier placement in educational programs, many of which have been the center of controversy, particularly in the past 15 years. 5. Emphasis on continued research and development of programs such as the Cochlear Implant.A historical review of deaf education is presented together with an evaluation of the various claims made by the supporters of the auditory‐oral vs. total communication techniques. No totally convincing argument for either system can be advanced. There is considerable doubt that the tri‐stimulus, or total communication approach to teaching of the deaf, has any superiority over the auditory‐oral approach. There are failures with both philosophies and the “deaf voice” is a stigma often associated with either system's graduates.A 13‐year follow‐up case study is presented in which the child was enrolled in an auditory‐oral program. Comments are made as the child was followed through home training to preschool and on to complete integration in the regular school system. The implications of such a study for the Otolaryngologist, particularly with regard to early identification in order to avoid linguistic delay, are outlined.
Alveolar pyogenic granuloma: Review and report of a case
Authors: Steven Moriconi E. , Popowich L. D. 
Published: October 2006

AbstractA large exophytic bone‐resorbing lesion was discovered in the oral cavity of an institutionalized 33‐ycar‐old male. An excisional biopsy under general anesthesia was performed. Frozen and permanent histologic sections confirmed a reactive gingival fibroma consistent with a pyogenic granuloma. This lesion is unusual in that it attained a very large size and caused marked remodeling of the alveolar bone of the mandible. Of interest as well, this highly vascular lesion was found to have numerous feeding vessels from the alveolar bone. A retained tooth root was encountered within the lesion, presumably the etiologic factor producing this lesion. A differential diagnosis is presented and discussed. The lesion should be of particular interest to otolaryngologists who deal with intraoral lesions and their treatment, since it illustrates an extreme presentation of a totally benign process.
Nasopharyngeal brain heterotopia – A cause of upper airway obstruction in infancy
Authors: Seibert Robert W. , Seibert Joanna J. , Jimenez Jorge F. , Angtuaco Edgardo J. 
Published: October 2006

AbstractThe finding of mature neuroglial tissue in a mass from the head and neck region of a child raises four differential diagnostic possibilities: teratoma, encephalocelc, glioma, and heterotopic brain tissue. We present a review of the literature and discuss the clinical, radiographical, and pathological features of a rare nasopharyngeal brain heterotopia in an infant causing upper airway obstruction.
Cystic metastasis from occult tonsillar primary simulating branchiogenic carcinoma: The case for tonsillectomy as a “grand biopsy.”
Authors: Marlowe Frank I. , Goodman Roy S. , Mobini Jalal , Dave Uday 
Published: October 2006

AbstractThe occult primary is a problem well known to head and neck surgeons. Less frequently discussed, but well documented, is cystic degeneration of metastatic nodes. When these conditions combine, they can suggest tumor arising in a pre‐existing cervical cyst. This is a controversial condition, rare if it occurs at all, and is not to be invoked lightly.
Visual loss associated with orbital and sinus diseases.
Authors: Manigila Anthony J. , Kronberg Frank G. , Culbertson William 
Published: October 2006

AbstractVisual loss associated with orbital and sinuses diseases is mainly due to infectious processes, trauma and neoplasm. From 1975 to 1983, we have encountered 34 such cases.The most common cause in our series was infectious processes, either due to aerobic or anaerobic bacteria or fungi (aspergillosis and phycomycosis). Iatrogenic trauma resulting in complete unilateral irreversible blindness was the second most common etiology in the series of cases that came to our attention for several reasons.Three of our patients with complete blindness, even with documented absence of light perception, secondary to infections or mucocele, underwent emergency surgical treatment with successful restoration of vision. Other patients with various degrees of visual loss experienced improvement, often to normal levels, when timely appropriate surgical treatment was applied.Orbital or optic nerve decompression was used according to pathologic findings encountered. High resolution CT scan has been very helpful in precisely pinpointing the lesion. It is also indispensable in the follow‐up of orbital abscesses in order to rule out intracranial complications. Blindness with immediate onset secondary to either external or iatrogenic trauma, with rare exceptions, has a dismal prognosis.Early diagnosis and prompt treatment are essential for salvage of vision or even lives of patients affected by such dreadful complications.
Twenty‐Five years experience treating Cerebro‐Rhino‐Orbital mucormycosis.
Authors: Abedi Esrafil , Sismanis Aristides , Choi Kwang , Pastore Peter 
Published: October 2006

AbstractMucormycosis is an acute fungal disease with high mortality exhibiting craniofacial, pulmonary, cutaneous, gastrointestinal and disseminated forms.Cerebro‐rhino‐orbital (CRO) mycormycosis is the type that most frequently involves the structures of the head and neck. While usually non‐pathogenic, these saprophytic organisms can be particularly lethal in chronically debilitated patients. Between the years 1957 and 1982, 18 cases of CRO mucormycosis were seen at the Medical College of Virginia Hospital and the McGuire VA Medical Center. Four illustrative cases of CRO mycormycosis are presented to emphasize: the importance of clinical awareness of the disease, the necessity of tissue biopsy for diagnosis, the need of appropriate management of any underlying disorder, administration of amphotericin‐B, and the performance of adequate surgery.
Nonbacterial inflammation as a means of enhancing skin flap survival.
Authors: Liston Stephen L. 
Published: October 2006

AbstractPainting the skin of the dorsum of a rat with croton oil improved the survival length of caudally based skin flaps. No vasodilation was demonstrated in the deeper layers of skin treated with croton oil. The mechanism by which the application of croton oil leads to improvement of the skin flap survival is thought to be the nonbacterial inflammation produced by the croton oil (a chemical burn). This inflammatory effect probably acts upon the microcirculation via arachidonic acid metabolite mediators.
Occult metastases in cancer of the larynx and their relationship to clinical and histological aspects of the primary tumor: A Four‐Year multicentric research.
Authors: Bocca Ettore , Calearo Carlo , Vincentiis Italo De , Marullo Tommaso , Motta Giovanni , Ottaviani Antonio 
Published: October 2006

AbstractThe authors have tried to verify whether some clinical or pathological features of laryngeal cancer may favor the occurrence of occult metastases in the lymphnodes of the neck in No cases. The purpose of the investigation was to define the possible existence of tumors, where elective neck dissection, in the absence of palpable nodes, could be done without, thus contributing to settlement of a long debated problem.Different parameters, both clinical and pathological, have been considered. The result of a cross comparison of such parameters in 237 cases of cancer of the larynx without palpable nodes, submitted to surgery on the primary and elective neck dissection, indicates that, although the frequency of occult metastases is significantly related to the site and size of the tumor, its grading, and the degree and type of stromal reaction, the favorable concurrence of all said parameters occurs in 2% of cases only. However, if only clinical parameters, viz. site and size of tumor, are taken into account, a favorable concurrence occurs in 18% of cases with an incidence of occult metastases lower than 2%. These cases are almost exclusively represented by T1No supraglottic and T2N0 glottic tumors. We can conclude by saying that clinical and pathological preoperative findings may offer a useful clue in evaluating the risk of occult metastases, and hence advising, or not, an elective neck dissection in No cases. Nevertheles, in the vast majority of cases, an elective functional neck dissection still offers the best guarantee of oncologic safety while avoiding unnecessary mutilation.
Sphenoid wing meningioma occurring as a lateral orbital mass.
Authors: Leipzig Bruce , English Jim 
Published: October 2006

AbstractThe differential diagnosis of a mass presenting in the lateral aspect of the orbit with bony erosion and involving the skin includes many malignancies, predominantly sarcomas. A total evaluation of the mass to include histopathologic characteristics and the true extent of the disease is critical to proper management of the patient.A 68‐year‐old man was referred for therapy with a diagnosis of fibrosarcoma. Evaluation of the disease revealed contiguous tumor from the right temporal region into the posterior orbit, with displacement of the globe and extension intracranially. During operation a frozen section analysis of the tumor was also interpreted as fibrosarcoma. A craniofacial resection was performed, including orbital exenteration and resection of a large 10 × 12 cm segment of attached dura. There was no evidence of extension into the brain. Final pathologic evaluation of the tumor was meningioma rather than fibrosarcoma. This unusual presentation of a meningioma has never been reported in the medical literature. The difficulty with interpretation of the original biopies will be discussed, as well as the management of this case.
Curved laryngotelescope.
Authors: Saito Shigeji , Fukuda Hiroyuki , Kitahara Satoshi , Isogai Yutaka 
Published: October 2006

AbstractThe purpose of this paper is to report on a newly developed curved laryngotelescope whose shape allows for smooth insertion through the oral and to the laryngeal cavity. Its principle of image processing involves lenses and prisms, which results in the maximum magnification of x6. Therefore, it is very useful for microscopic examination. We can obtain a clearer picture by this device than by conventional laryngoscopes. Examination with this laryngotelescope is easily performed after only topical application of a local anesthetic and patients experience less pain.

Head and neck manifestations of the chronic graft vs. host disease
Authors: Medina Jesus E. , Frame Robert , Nguyen Lu , Toth Bela , Luna Mario A. 
Published: October 2006

AbstractBone marrow transplantations are being used with increasing frequency in the treatment of patients with leukemia and aplastic anemia. The graft‐vs.‐host disease (GVHD) is a serious complication that affects long‐term survivors following bone marrow transplantation. It is the result of an immunologic reaction mounted by the grafted reticuloendothelial cells against the tissues of the recipient, and it affects multiple organ systems. Involvement of the skin and mucosal surfaces of the head and neck region, in particular the oral cavity, occurs in a large number of patients with GVHD. In this report we present four patients with GVHD in whom mucosal lesions and infections of the head and neck region were prominent features. Our observations indicate that the clinical and histological characteristics of these lesions vary according to the time elapsed from the onset of the disease. Therefore, clinical examination of the head and neck region and biopsy of the oral mucosa are important not only in the diagnosis of the GVHD, but also in the evaluation of its progress and response to treatment.
