Computed tomography in choanal atresia
Authors: Kearns Donald B. , Wickstead Michael , Choa Dennis I. , Leitch Rosalind N. , Bailey Martin , Evans J. N. J. 
Published: November 2007

AbstractComputed tomography is replacing contrast radiography as the method of choice in evaluating congenital posterior choanal atresia. Careful preparation of the patient, however, is necessary prior to the examination in order to obtain the maximum of information pre-operatively.We present patients with inadequate preparation and illustrate their misleading scans. The proper method of examination is discussed, with a review of the literature; it is essential to remove nasal secretions by suction and instil vasoconstrictor nose drops, shortly before scanning.
Serum immunoglobulin E levels in patients with head and neck cancer
Authors: Lal Harbans , Singh Bharat , Wig Umesh , Saini A. S. 
Published: November 2007

AbstractSerum immunoglobulin E levels were estimated in 50 patients with head and neck cancer and in 25 controls. Mean serum IgE value was significantly higher in patients with various sites of cancer in the head and neck region other than carcinoma of the tonsil. The levels increased with advancement in the stage of cancer. There was, however, no difference in mean serum IgE value with respect to the character of the lesion, to the histopathological type of growth or to radiotherapy.In patients with carcinoma of the tonsil, the mean serum IgE concentration was significantly lowered.
Oculomotor findings in autistic children
Authors: Rosenhall Ulf , Johansson Elisabeth , Gillberg Christopher 
Published: November 2007

AbstractEleven children with infantile autism or autistic-like conditions were examined with oculomotor tests and with auditory brainstem response audiometry. Measurements of voluntary, horizontal non-predictable saccades showed that the eye motor function was abnormal in six (55 per cent) of the eleven patients. The saccades were hypometric in all six instances and the saccadic velocity was reduced in four instances. The abnormalities observed are consistent with brain dysfunction, in most cases probably indicating ponto-cerebellar involvement. In five instances ABR was found to be abnormal which indicates brainstem dysfunction. Oculomotor dysfunction and/or ABR abnormality was observed in eight (73 per cent) of the patients studied.
Lymphoplasmacytic lymphoma of the larynx, soft palate and nasal cavity
Authors: Bickerton R. C. , Brockbank M. J. 
Published: November 2007

AbstractNon-Hodgkin's lymphoma of the larynx is uncommon and when it occurs presents as a non-ulcerating supraglottic mass with a predilection for the ventricle. No case of the lymphoplasmacytic variety occurring in the larynx has been reported in the literature to date. We present such a case with distant leisons in the soft palate and nasal cavity, mimicking nasal polyps.
Interest in frozen section examination of margins and lymph nodes in laryngeal surgery
Authors: Remacle M. , Hamoir M. , Marbaix E. , Deggouj N. , Frederickx Y. 
Published: November 2007

AbstractOne hundred and one patients presenting with a squamous cell carcinoma of the larynx underwent surgery i n our department between January 1980 and May 1985. In most of these patients, nodes were removed from the main lymphatic drainage pathways and subjected to immediate frozen section examination. The results from frozen section examination of the nodes were then compared with those from the surgical specimens of cervical neck dissections performed on the patients according to the classic rules. In addition, margin resections were made and examined by frozen section after removal of the tumour. In the event of a positive finding, these resections were continued until healthy tissue was reached, the specimens being examined in addition by classic methods.Immediate frozen sections enable the margins of the resection to be verified correctly. In our series we were brought to extend the limits of resection in 10 cases out of 68 (15 per cent). It can also be seen that the accuracy of the pathologist's reading of the frozen sections is satisfactory. The overal level of error is three out of 68 (4.5 per cent). All the errors correspond to false negatives.The aim of avoiding neck dissections in the presence of N0, thanks to nodal selection with frozen section, is not attained. We find a 6/61 rate of false negatives for N0 - N1 (10 per cent) when we compare the frozen sections of the selected nodes and the neck dissections. This is due to the fact that the surgeon may be led astray by a reactive hyperplastic node whilst other less inflammatory neighbouring nodes are in fact the site of metastasis.
Cranioplasty with Palacos R in reconstruction of frontal sinus defects
Authors: Mann W. , El-Khatieb A. A. 
Published: November 2007

AbstractThe use of methylmetacrylates has not been widely accepted for the repair of frontal bony defects due to the possibility of secondary infection. The development of a new type of methylmetacrylates into which antibiotics, such as gen-tamicin, are incorporated has reduced the risk of secondary infection.The surgical technique and the results are illustrated on three patients. Favourable results were obtained in small and in large bony defects and even after previous frontal osteomyelitis.
Nasal septal carcinoma: initial symptom of nasal septal perforation
Authors: Echeverria-Zumarraga M. , Kaiser C. , Gavilan C. 
Published: November 2007

AbstractA case of a primary squamous cell carcinoma of the nasal septum in a young female with initial symptom of septal perforation is reported. Carcinoma of the nasal septum is an uncommon entity and there are a few cases reported in the literature. The functional impact of their treatment and the high mortality makes it important to diagnose it at early stage. We discuss the differential diagnosis of septal perforation and recommend early wide surgical excision.
Liposarcoma of the larynx

AbstractLiposarcomas of the larynx are very rare. Only nine cases appear to have been recorded in the English literature.An additional case of liposarcoma of the larynx occurring in a young patient is reported and the relevant literature discussed.
Otosclerosis—an inflammatory disease of the otic capsule of viral aetiology?
Authors: Arnold W. , Friedmann I. 
Published: November 2007

AbstractFragments of otospongiotic and otosclerotic footplates were investigated by immunohistochemical methods. Antibodies IgG, IgA, IgM were found to be found to the vascular connective tissue of the resorption lacunae, IgG also to osteocytes. The application of antibodies against mumps, measles and rubella antigens showed the expression of the relevant viral antigens in the large cells of the resorption lacunae, in the vascular connective tissue, and in osteocytes, osteoclasts and chondrocytes, present in or around the otospongiotic areas. In the sclerotic stage only the perivascular connective tissue and chondrocytes have expressed viral antigens whereas IgG was restricted to the osteocytes of the sclerotic focus and to the residual perivascular tissue. Two footplates with postinflammatory sclerosis serving as controls revelaed only IgG in some chondrocytes. Healthy footplates showed neither a deposition of antibodies nor any expression of viral antigens. These results favour a viral aetiology of otosclerosis as an inflammatory vasclar reaction of the otic capsule initiated or caused by the viruses of measles, rubella and mumps.
The effect of vidian neurectomy on nasal mucociliary clearance
Authors: Greenstone M. A. , Stanley P. J. , Mackay I. S. , Cole P. J. 
Published: November 2007

AbstractThe physiological factors controlling mucociliary transport are largely unknown. Nasal mucociliary clearance was measuredusing the saccharin test in seven patients who had previously undergone vidian neurectomy for vasomotor rhinitis. Persistent denervation was suggested by impaired tear secretion. The control group consisted of thirty-four patients with vasomotor rhinitis who had not had surgery. There was no significant difference in clearance times between the two groups, suggesting that mucociliary transport is well preservedin the absence of neural control.
Osteoclast-type giant cell neoplasms of the parotid gland
Authors: Batsakis John G. , Ordonez Nelson G. , Sevidal Pedro A. , Baker James R. 
Published: November 2007

AbstractThe parotid gland is added to the list of parenchymal organs, notably the pancreas, in which osteoclast-like cells appear as constituent cells in their neoplasms. The cells' role in the neoplasms is a reactive one or, more rarely, as an integral element in an osteoclast-type giant cell neoplasm or so-called osteoclastoma. Distinctive in histological appearance, the osteoclast-type giant cell neoplasm is a malignant lesion that, to date, has been described only in the pancreas and parotid glands. This report presents examples of each type of giant cell lesion in the parotid gland.
Papillary endothelial hyperplasia in the nose
Authors: Stevens D. J. 
Published: November 2007

AbstractBenign papillary endothelial hyperplasia is a very rare lesion of the nasal cavity; histologically, it may be mistaken for an angiosarcoma. An awareness of this and the ways in which it differs from angiosarcoma will prevent incorrect diagnosis and inappropriate treatment by surgery or radiotherapy. A case report of each condition involving the nasal cavity is presented.
Kaposi's sarcoma of the trachea
Authors: Rajaratnam K. , Desai S. 
Published: November 2007

AbstractThe most common tracheal neoplasms are epidermoid carcinomas, papillomas and cylindromas. Kaposi's sarcoma, confined primarily to the trachea, is one of the rarest tumours. The clinical and histological picture of a case of Kaposi's sarcoma of the trachea in a young, pregnant woman, presenting with severe airway obstruction, is described here. The emergency tracheoscopy dislodged a mass from the trachea, which turned out to be a Kaposi's sarcoma on histology. Although Kaposi's sarcoma is one of the manifestations of AIDS, this patient had neither any underlying immunodeficiency nor any skin, visceral or lymphatic lesions.
Accessory nerve schwannoma extending extracranially to the second cervical level of vertebra

Published: November 2007

AbstractWe described a 67-year-old man who had a right jugular foramen tumour expanding extracranially to the level of C2 cervical body. Paralysis of the glossopharyngeal, vagal, accessory, hypoglossal nerves and sensorineural hearing disturbance were found. The tumour originated from the accessory nerve and the histological examination revealed it was schwannoma. Accessory nerve as an origin of the jugular foramen neurinoma and its pre-operative neurological signs are reviewed.
Aetiology of bilateral sensorineural deafness in children
Authors: Das V. K. 
Published: November 2007

AbstractThe study was carried out in children born during the four year period 1981–1984 in the Greater Manchester County. The children were investigated for possible congenital infections. Perinatal assessment was carried out for adverse aetiological factors. Family histories were obtained and parents and siblings were examined for any hearing impairment. A total of 164 cases were investigated. Various aetiological groups were formed which showed the following distribution: cause unknown 36.5 per cent; genetic group 20.1 per cent; adverse perinatal factors 14.6 per cent; congenital infections 9.8 per cent; meningitis 6.1 per cent; chromosomal abnormalities 3.7 per cent; syndromal group 3.7 per cent; and miscellaneous 5.5 per cent. The findings are discussed in the light of previous studies.
Down's syndrome with lingual tonsil hypertrophy producing sleep apnoea
Authors: Phillips D. E. , Rogers J. H. 
Published: November 2007

AbstractA 12-year-old girl is presented with Down's syndrome and lingual tonsillitis causing sleep apnoea. In order to overcome her sleep apnoea she adopted a functional sleeping posture. The sleep apnoea was successfully treated by a single staged lingual tonsillectomy without preliminary tracheostomy. A return to a normal sleeping posture occurred spontaneously in the early post-operative period.
Local iatrogenic complications in nasopharyngeal rhinoscleroma
Authors: Dawlatly E. E. , Anim J. T. , Baraka M. E. 
Published: November 2007

AbstractThe possible role of surgical manipulation in inducing local spread and cicatricial complications in rhinoscleroma is illustrated by the three cases discussed in this paper. This is especially so where is occasional presentation as polypoid lesions of the lower respiratory tract may mimic other more sinister lesions and lead to unwarranted invasive procedures by the unsuspecting clinician. The infective nature of the lesions must be appreciated and confirmed microbiologically for appropriate drug treatment to be used. The benefits of minimal surgical intervention are illustrated in the third case.
Induction cytotoxic chemotherapy: The significance of apparent complete clinical regression after using the Price Hill Schedule A protocol for squamous carcinoma of the head and neck
Authors: Shaw H. J. 
Published: November 2007

AbstractA small group of 46 previously untreated patients out of about 260 in all who have received Price Hill schedule A cytotoxic chemotherapy, achieved apparent complete clinical regression (ACCR) of their disease before local treatment. Forty patients were classified T3 or T4, over half having clinically positive nodes at the start of treatment.A determine survival rate of 70 per cent disease free at three years was obtained and 74 per cent achieved quality of all symptoms. Two patients declined local treatment and survived three years disease free after chemotherapy alone. No recurrence has occurred to date in seven patients achieving apparent complete histological regression (ACHAR) in their surgical specimens.Although ACCR does not automatically improve prognosis it is likely that it does enhance the complete remission rate, especially for those also achieving ACHR.Benefits to patients obtaining ACCR with this minimally toxic chemotherapy schedule and listed.

Presence of an ectopic canine tooth under the orbital floor was a noticeable feature of this case. The clinical presentation, radiological, and histological aspects and treatment have been reviewed.
Rhabdomyoma of the tongue
Authors: Boysen M. , Scott H. , Hovig T. , Wetteland J. , Kolbenstvedt A. 
Published: November 2007

AbstractAdult rhabdomyoma is a benign neoplasm of skeletal muscle origin, which mainly occurs in the head and neck region. Because of its rarity the diagnosis may be missed, especially if cross-striations cannot be demonstrated by light microscopy. By applying supplementary diagnostic evaluation with immunohistochemistry and electron microscopy, the diagnosis is established. Positive staining with desmin unequivocally demonstrates that the tumour cells are derived from muscle tissue. The presence of myofibrils, Z-bands and numerous mitochondria by ultrastructural examination are characteristic features of this tumour.
Carcinoid tumour of the middle ear
Authors: Kodama H. , Takezawa H. , Suzuki T. , Kobayashi K. , Kataura A. , Wakabayashi J. , Satoh M. 
Published: November 2007

AbstractCarcinoid tumours belong to the rarer neoplasms of the middle ear. In 1980, Murphy et al. described the first case of a carcinoid tumour of the middle ear. Only five cases could be traced in the literature. The light and electron microscope features of a primary atypical carcinoid tumour of the middle ear are presented and compared with those described in the literature. Primary carcinoid of the middle ear appears to be derived from the epithelial lining of the middle ear. Distant metastases have not been reported. The duration and nature of the symptoms are of little diagnostic value. An atypical carcinoid tumour in the left ear of a 33-year-old woman is described.
Primary cholesteatoma of the mastoid presenting as cervical abscess

Published: November 2007

AbstractPrimary cholesteatoma has been described in a number of sites within the temporal bone. We report an unusual case of primary cholesteatoma, confined to the mastoid, presenting with a Bezold's abscess of the anterior cervical triangle, in an otherwise asymptomatic elderly man with normal hearing.
Temporal bone venous anomaly of surgical significance
Authors: Shotton J. C. , Ludman H. , Cox T.C.S. 
Published: November 2007

AbstractVariability in the size of the dural sinuses and jugular bulb is not uncommon and usually manifests as a high jugular bulb encroaching upon the floor of the middle ear. A rarer entity is the superior and medial extension of the jugular bulb into the bone of the posterior wall of the internal auditory meatus. We report a case where this anomaly was encountered during acoustic neuroma surgery making exposure of the fundus of the internal auditory meatus technically impossible. The possibility of a communication with the superior petrosal sinus is discussed.
Tensa retraction cholesteatoma: treatment and long-term results
Authors: Lau T. , Tos M. 
Published: November 2007

AbstractTo obtain the best possible results of treatment of acquired cholesteatoma, we made a subdivision of cholesteatoma types into attic and pars tensa cholesteatomas, and subdivided the latter further into tensa retraction cholesteatoma and sinus cholesteatomas. Tensa retraction cholesteatoma is defined as arising from a retraction or perforation of the whole pars tensa, whereas sinus cholesteatoma is defined as arising from a retraction or perforation of the postero-superior part of the tensa. We present the long-term results obtained in tensa retraction cholesteatomas treated with one stage surgery from 1964 to 1980. Median observation time was 9 years, range 2 to 19 years. Sixty-one ears were treated without mastoidectomy, whereas 71 ears had canal wall-up mastoidectomy and 64 ears had canal wall-down mastoidectomy. The total recurrence rate was 13.3 per cent; 17 ears had residual cholesteatoma, and nine ears had recurrent cholesteatoma. The best results were obtained in ears with an intact ossicular chain where mastoidectomy was not performed. In 49 per cent of the cases, the cholesteatoma was confined to the tympanic cavity without reaching the aditus, antrum or mastoid process. About one-third to one-quarter of the ears had tympanoplasty only, with removal of the cholesteatoma through the ear canal.
Total parotidectomy—a routine treatment for parotid gland swellings?
Authors: Alajmo E. , Polli G. , De Meester W. 
Published: November 2007

AbstractThe results of 25 years of quasi-routine total parotidectomy performance are shown. At the Department of Otolaryngology of the University of Florence, 582 patients were treated as follows: on 527 occasions by total parotidectomy with facial never preservation; 24 occasions by lateral lobectomy; 27 occasions by total parotidectomy with removal of the whole facial nerve; four times by enucleo-resection of the disease. Benign tumours were 378; primary and metastatic malignant tumours—100; non tumoral lesions—104.The benign tumours follow-up showed three recurrences only (two pleomorphic adenomas—one of them proved to be an adenoid-cystic carcinoma, and one monomorphic adenoma, which also proved to be an adenoid-cystic carcinoma), respectively 6, 6 and 8 years later. The malignant tumours were also treated by total parotidectomy with adequate management both of the facial nerve and the neck lymph nodes. The results thoroughly justify the nerve preservation, when preserved.
Haemangiopericytoma of the larynx

Published: November 2007

AbstractHaemangiopericytoma is an uncommon vascular tumour which has rarely been recorded in the larynx. The diagnostic and histopathological difficulties are discussed. A total laryngectomy was performed because of the size and site of the tumour, the associated risk of local recurrence and the high metastatic rate.
Occasional stapes surgery—a Norwegian experience
Authors: Mair I. W. S. 
Published: November 2007

AbstractThe past history of, and current trend in, stapes surgery are reviewed, and experience from a personal series of 128 procedures over an 18 year period is presented. Results are frequently poorer than many surgeons and their patients anticipate, and more stringent pre-operative case selection and centralisation of surgical activity would appear desirable. Amplification has become a more acceptable management alternative for some patient categories.
Cephalometric analysis in patients with obstructive sleep apnoea syndrome.
Authors: Lyberg T. , Krogstad O. , Djupesland G. 
Published: November 2007

AbstractFacial skeletal morphology was studied by cephalometric analysis in 25 patients with obstructive sleep apnoea syndrome (OSAS) and ten controls. The hyoid bone was more inferiorly positioned in patients (at the level of cervical vertebrae C4-C6) than in controls (C3-C4 level). The height and length of the nasal cavity was normal, while the length of the bony nasopharynx was moderately reduced. The mandibular plane inclination was slightly larger in patients as was the anterior face height. Mandibular retrognathia was demonstrated in six patients (24 per cent), but the angles of maxillary and mandibular prognathism was within normal limits when the group was considered as a unity. Cephalometric analysis is highly recommended as a diagnostic aid in OSAS patients, especially when surgical intervention is considered.
Role of masseter crossover flap in oropharyngeal reconstruction
Authors: Tiwari R. M. , Snow G. B. 
Published: November 2007

AbstractOropharyngeal reconstruction especially after surgery for medially located lesions of moderate dimensions presents a challenge. The risk of using well vascularized, but insensitive tissues close to the airway has led to the development of several measures to overcome the difficulties involved. The transposition of masseter muscle which has been put forward in recent years provides successful primary closure with preservation of function.
Tongue metastasis from carcinoma of the rectum
Authors: Davidson N. G. P. , Wilson A. 
Published: November 2007

AbstractA case report of a patient with carcinoma of the rectum with metastasis to the tongue clinically mimicking a primary tongue neoplasm is described. The patient presented with an ulcer in the tongue three years after undergoing an anterior resection for a Dukes C carcinoma of the rectum. Other asymptomatic metastatic lesions were discovered only after the histology report suggested that the tongue ulcer biopsy was metastatic in origin. Metastatic tumour to the tongue is extremely rare and often occurs at a late stage, when there is disseminated disease. We are not aware of any reported case of tongue metastasis from carcinoma of the rectum.
