Surgery for external auditory canal exostoses and osteomata
Authors: Fisher Edward W. , McManus Terence C. 
Published: November 2007

AbstractThe popularity of water sports in Western Australia results in a high demand for surgery for meatal exostoses when compared to Europe or North America, and such procedures for advanced exostoses present a technical challenge.We report on a decade of experience in exostosis and osteoma surgery consisting of 127 procedures on 102 patients. Exostectomy was an access manoeuvre for other otological procedures in 13 cases and five procedures were for regrowth of exostoses. Minor complications were seen after 22 per cent of operations. Major complications were experienced after five per cent for example canal stenosis, temporomandibular joint prolapse, sensorineural loss, persistent deep bony lip and persistent tympanic membrane perforation. There were no facial palsies.Exostosis surgery should be reserved for failed conservative treatment and attention focused on adequate access, meatal skin preservation and tympanic membrane protection. An approach which concentrates on safe anterior landmarks and wide exposure is recommended to avoid serious complications.
The styloid process in ossicular chain reconstruction. II: Long-term analysis
Authors: Ogale S. B. , Dutt Sunil N. , Thakur Sugato , Pawar Manisha 
Published: November 2007

AbstractThe human cadaveric styloid process was used as a homograft material for ossicular chain reconstruction in 41 cases of chronic suppurative otitis media over a five-year period. Although technical success was achieved in about 88.23 per cent of the cases, actual patient benefit was around 70.58 per cent; this is comparable to results obtained with most other homologous graft materials. The problem of breakage while remodelling the bone has also increased the risk of transmitting the AIDS virus and consequently undermines the use of this material.
A prospective evaluation of direct referral to audiology departments for hearing aids
Authors: Swan I. R. C. , Browning G. G. 
Published: November 2007

AbstractIt has been suggested that a proportion of individuals with a hearing impairment can be fitted with a hearing aid without being otolaryngologically assessed. Such assessments are deemed advisable: (a) to identify otological pathology that might require management and (b) because surgery can be a viable alternative in those with a conductive impairment.The aim of this study was to prospectively study individuals referred to an Otolaryngology Department in a teaching hospital to assess how technicians, at a direct referral clinic for the provision of a hearing aid, could screen to identify those meriting an otolaryngological opinion. Two hundred and forty-eight patients were evaluated by technicians using strict audiometric and tympanometric criteria. One hundred and twenty-five patients (50 per cent) failed these criteria and were referred to an otologist. The remaining 123 (50 per cent) were managed by technicians but were subsequently reviewed for the purpose of this study by an otologist and their management assessed. In only two patients (one per cent) was it thought that the initial management would have been different if seen by an otologist. Alternative criteria for deciding suitability for management by technicians were applied. The inclusion of tympanometry was essential to avoid missing middle ear pathology.
Coffin-Lowry syndrome with sensorineural deafness and labyrinthine anomaly
Authors: Higashi Koichiro , Matsuki Chikako 
Published: November 2007

AbstractA case of Coffin-Lowry syndrome is described. The child had the typical face and also soft and puffy hands with tapering fingers. His psychomotor development was retarded. Audiological tests revealed profound hearing impairment. Anomalous labyrinths were shown by CT scan of the temporal bones. It is inferred that deafness is one of the symptoms of this syndrome.
An extensive vestibular schwannoma with both intracranial spread and lateral extension to the external auditory canal
Authors: Woolford T. J. , Birzgalis A. R. , Ramsden R. T. 
Published: November 2007

AbstractAn extensive schwannoma in a 54-year-old woman is described. There was extension intracranially to involve the brain stem, laterally to fill the middle ear and external meatus, and inferiorly into the infratemporal fossa. Initially the intracranial portion of the tumour was excised. Later a second operation was undertaken to remove the residual tumour from the temporal bone and infratemporal fossa.
Rosai—Dorfman disease of the paranasal sinuses
Authors: Gregor R. T. , Ninnin D. 
Published: November 2007

AbstractA 57-year-old man presented with a history of nasal obstruction of five to six years duration. 'Nasal polyps' were removed on several occasions. He had previously had an episode of paraplegia which resolved after the removal of a spinal tumour. Histology from both sites was thought to represent a malignant fibrous histiocytoma. On presentation the patient had computed tomographical (CT) evidence of extensive ethmoidal disease, with threatened intracranial extension. He also had evidence of lung and retroperitoneal disease with pancreas and kidney involvement. The ethmoidal disease was considered potentially lethal and therefore a craniofacial resection was performed. Review of all the histology revealed that the diagnosis was extranodal Rosai–Dorfman disease (sinus histiocytosis). The patient's course is described, and the literature on this disease of unknown aetiology is reviewed.
Subtotal petrosectomy with external canal overclosure in the management of chronic suppurative otitis media
Authors: Parikh Abhi A. , Brookes Gerald B. 
Published: November 2007

AbstractSubtotal petrosectomy with external canal overclosure has been used in the management of 10 patients with chronic suppurative otitis media in the past four years. These patients fall into two categories. One group consisted of patients with end-stage chronically discharging mastoid cavities, despite aggressive medical therapy. The other group comprised patients who had developed disabling peripheral vestibular symptoms and had a mastoid cavity from past surgery for chronic otitis media. In both groups the affected ear had absent or poor auditory function. In the second group, a translabyrinthine section of the vestibular and/or cochlear nerves was performed in conjunction with subtotal petrosectomyThe procedure has been very successful in relieving the persistent otorrhoea, giving the patient an ear without a cavity that would need regular care. No restriction on swimming and participation in other water sports is an additional advantage.Illustrative cases are used to discuss the technique and indications.
Primary tumours of the trachea: analysis of clinical features and treatment results
Authors: Howard David J. , Haribhakti Vijay V. 
Published: November 2007

AbstractPrimary tracheal tumours are extremely rare and present with widely variant clinical and histological features. Treatment methods vary considerably, and few studies have sought to provide adequate guidelines. A retrospective analysis was carried out of all patients treated in our unit between 1965 and 1990. Our experience deals almost exclusively with high tracheal tumours involving the adjacent subglottic region. Squamous carcinoma (SCC) and adenoid cystic carcinoma (ACC) were the commonest subtypes, and presented with dyspnoea and hoarseness as the most frequent symptoms. ACCs occurred commonly in young individuals, presented insidiously, and ran a long, and often, unpredictable course. Endoscopic evaluation revealed the majority of the lesions to be bulky and obstructive in nature. Primary surgery with adjuvant radical radiotherapy, when indicated, appeared to provide optimal results. Debulking surgery followed by radiotherapy provided effective and lasting control in two cases of ACC. Other malignant subtypes behaved aggressively and progressed uncontrolled.
In vitro comparison of the Groningen high resistance, Groningen low resistance and Provox speaking valves
Authors: Heaton Judith M. , Parker Andrew J. 
Published: November 2007

AbstractThis paper compares the physical parameters of the newer Groningen low resistance and Provox indwelling laryngectomy prostheses with the established and original Groningen device.In vitro pressure/flow profiles were determined, using specially designed apparatus, in 44 standard Groningen high resistance (GHR), 37 Groningen low resistance (GLR) and 19 Provox tracheo-oesophageal prostheses prior to insertion. GHR valves had significantly higher forward opening pressures than both the newer valves and the GHR was significantly higher than the Provox (p<0.01: Mann-Whitney U-test). The mean forward resistance of GHR was significantly higher than that of both; the Provox valve was significantly lower than that of GLR (p<0.0001: Mann-Whitney U-test). This may be of relevance with respect to patient acceptability, voice quality and effective duration of valve action.

Published: November 2007

AbtractWe report on the case of a young woman, presenting with a left lateral neck lump, which turned out to be a bony callus originating from the thyroid cartilage; similar but smaller lesions were found on the same side in the hyoid and cricoid cartilages. The CT, MRI and pathological findings are described.
Cystic vestibular schwannomas: neuroimaging and growth rate
Authors: Charabi Samih , Mantoni Margit , Tos Mirko , Thomsen Jens 
Published: November 2007

AbstractIn a series of 571 vestibular schwannomas (VS) operated on in the period 1976–1992, via the translabyrinthine approach, 23 tumours (4 per cent) from 23 patients were radiologically, peroperatively and histologically identified as cystic VS. Neuroimaging examinations (CT and MRI) revealed 15 tumours (2.6 per cent) with extracystic formations and in eight cases (1.4 per cent) intratumoural cysts. In 15 cases (65 per cent), tumours were located extracanalicularly with no involvement of the internal auditory canal (IAC). The extracanalicular tumour extension including the cystic elements ranged between 10 and 60 mm with a mean of 45 mm. In eight cases out of 23 (35 per cent) other diagnostic possibilities such as trigeminal schwannoma, epidermoid cyst and meningioma were proposed at the primary evaluation. Deformation, displacement and/or impression of the fourth ventricle was demonstrated in 17 cases (74 per cent). Three patients (13 per cent) had obstructive hydrocephalus which demanded shunt insertion. Residual tumour was detected in two patients (9 per cent). Growth rate in four cases was more than 10 times higher when compared to the annual growth rate of noncystic VS. The results of this study provide data on cystic VS attenuation demonstrated by CT or MRI which may be valuable in neuroradiological diagnosis of these cystic lesions and emphasizes that the wait-and-see policy should not be applied to the cystic variant of VS.
The Foley catheter in epistaxis management – a scientific appraisal
Authors: Hartley C. , Axon P. R. 
Published: November 2007

AbstractThe Foley balloon catheter has been used in the management of posterior epistaxis for several decades. Despite a lack of uniformity in balloon use, it is frequently successful in arresting haemorrhage. A better understanding of the balloon's characteristics may further increase its effectiveness by more appropriate use in some individuals.Inflation characteristics were assessed in vitro by measurement of balloon length and diameter at various inflation volumes. Deflation of air-filled balloons was found to be consistent for each balloon type. The deflation rate was unaffected when BIPP (bismuth-iodoform-paraffin paste) or liquid paraffin soaked gauze were applied to the catheter.Recommendations for catheter use are made.
Importance of pre-operative recognition of the nonrecurrent laryngeal nerve
Authors: Nagayama Ikuo , Okabe Yozo , Katoh Hideaki , Furukawa Mitsuru 
Published: November 2007

AbstractThe nonrecurrent laryngeal nerve is vulnerable during thyroid surgery. Pre-operative recognition of this nerve allows surgeons to avoid injuring the nerve. This anomaly depends upon the aortic arch anomaly and, therefore, in some cases, surgeons are able to predict the presence of this nerve pre-operatively by chest X-ray or barium swallow. Two patients with nonrecurrent laryngeal nerve are reported, one of whom, a 48-year-old man, had an abnormal shadow of the aortic arch, which led to confirmation of a right aberrant subclavian artery. Barium swallow plays a decisive role in the diagnosis of nonrecurrent laryngeal nerve, and this test is mandatory in patients who complain of difficulty in swallowing.

AbstractFour cases with a neopharyngeal diverticulum following total laryngectomy are presented. Each patient required surgery for complications directly related to the pouch. The relevance of these diverticulae is discussed with reference to their aetiology, complications and management.
A unique congenital glossocervical fistula
Authors: Donnelly Martin J. , Timon Conard I. , Mooney Eoghan 
Published: November 2007

AbstractLateral cervical fistulae which communicate with the oropharynx are considered to result from incomplete obliteration of the second branchial cleft and pouch. Classically these fistulae have a well-defined pathway through the neck. We present a case, and discuss the aetiology, of a fistula extending from the lateral neck via a previously undescribed course through the neck structures and opening into the posterior aspect of the tongue at the level of the vallate papillae.
Perilymphatic fistula—the value of diagnostic tests
Authors: Podoshin Ludwig , Fradis Milo , Ben-David Jacob , Berger Steven I. , Feiglin Hava 
Published: November 2007

AbstractPerilymphatic fistula (PLF) remains one of the most challenging problems in otological practice. Fifty-two consecutive patients (53 ears) who underwent explorative tympanotomy for suspected PLF between 1985–1992 were included in this study. The clinical picture, history, patients' complaints and laboratory tests were analysed and compared with the operative findings. The conclusions of our work are that the diagnosis of PLF is based mostly on the clinical picture and a battery of laboratory diagnostic tests, but no one test is truly diagnostic for PLF.
Sudden deafness and cerebellar tumour
Authors: Gálvez E. Merino , Meseguer D. Hellín , Ortega F. García , Mondejar J. Manuel 
Published: November 2007

AbstractWe report the case of a female patient who presented with sudden deafness as the first symptom of a cerebellar tumour which was not localized strictly in the cerebellopontine angle and did not show direct compression on the extrabulbar portion of the Vlllth cranial nerve. The clinical picture contained a number of signs and symptoms typical of cerebellar involvement.Surgical intervention restored the hearing and caused the symptoms to disappear.We also review the association between tumours and sudden deafness in the literature.
Severe chronic inflammation of the mucous membranes in the eyes and upper respiratory tract due to work-related exposure to hexavalent chromium
Authors: Johansen Morten , Overgaard Erik , Toft Arne 
Published: November 2007

AbstractChronic inflammation of the skin and mucous membranes following prolonged exposure to high doses of toxic hexavalent chromium is well known in the occupational medical literature. Perforation of the nasal septum is a cardinal clinical feature. Late development of cancer in the respiratory system is established. A recently diagnosed case with an unusually severe affect on the eyes is described. The industrial usage of chromium and its toxiological profile is reviewed.
A comparison of artificial saliva and pilocarpine in radiation induced xerostomia
Authors: Davies A. N. , Singer J. 
Published: November 2007

AbstractTwenty patients with radiation-induced xerostomia were entered into a prospective randomized crossover study comparing a mucin-based artificial saliva (Saliva Orthana) and a mouthwash containing pilocarpine 5 mg three times a day. Overall the patients found that the pilocarpine mouthwash was more effective than the artificial saliva in relieving their symptoms (p = 0.04), and 47 per cent of the patients wanted to continue with this treatment after the study had finished.
A case report of facial nerve palsy associated with chickenpox
Authors: Watanabe Yoshiharu , Ikeda Minoru , Kukimoto Nobuo , Kuga Mutsumi , Tomita Hiroshi 
Published: November 2007

AbstractWe examined a very unusual patient who developed peripheral facial palsy with chickenpox. A survey of the English literature revealed that eight such patients had been reported, but the period between the appearance of the vesicles of varicella and the facial nerve palsy ranged from five days before to 16 days after the eruption development. We presume that the route of infection was neurogenous in patients who had palsy after the appearance of the eruptions, but haematogenous in patients who had palsy before the appearance of vesicles. The two patients whose infection route was presumed to be haematogenous, had a poor prognosis.
Lipoma in the peri-tonsillar space
Authors: Tsunoda Atsunobu 
Published: November 2007

AbstractLipomas in the head and neck region usually occur in the immediate subcutaneous tissue, and only rarely in the upper aerodigestive tract. We report here a case of a 58-year-old female with a lipoma in the peri-tonsillar space. The tumour originated from the left peri-tonsillar space over the palate tonsil and partly protruded into the oral cavity. MRI (magnetic resonance imaging) showed not only the acccurate location of the tumour but also suggested its pathology. To our knowledge, a lipoma in the peri-tonsillar space is quite rare and MRI is useful in its diagnosis.

Published: November 2007

AbstractHigh-resolution computed tomography (HRCT) is important in the evaluation of cochlear implant candidates. This study examines the accuracy of radiological assessment of cochlear patency in relation to findings at the time of surgery. Older and newer HRCT methods and attending and senior radiologist interpretations are compared in a large series of cochlear implant patients.Subjects were 50 adults (22 to 74 years) and 31 children (2.4 to 11.7 years) who received either a 3M/House or a Nucleus 22-channel cochlear implant. Attending radiologist reports were obtained by chart review and the scans were re-reviewed for this study by a senior radiologist. Accuracy in detecting cochlear ossification ranged from 86.4 per cent for attending radiologists, with all HRCT scans, to 94.7 per cent for the senior radiologist with newer HRCT scans. False positives were rare, but false negatives did occur. Overall, best results were obtained with newer HRCT scans and a senior radiologist.Knowledge of the presence and extent of cochlear ossification is important to the implant surgeon and for patient counselling. Technical guidelines and a check list for interpretation of results are presented.

AbstractWe present a solar recharging system for nickel-cadmium cells of interest in areas where batteries for hearing aids are difficult to obtain. The charger has sun cells at the top. Luminous energy is converted into electrical energy, during the day and also at night if there is moonlight. The cost of the charger and hearing aid is very low at 35 US$.The use of solar recharging for hearing aids would be useful in alleviating the problems of deafness in parts of developing countries where there is no electricity.
The high jugular bulb in ear surgery: three case reports and a review of the literature
Authors: Moore Philip J. 
Published: November 2007

AbstractEncounters with the jugular bulb in ear surgery are uncommon. This communication relates three cases where the author was confronted with the bulb in middle ear surgery – one in relation to the external auditory canal when raising a tympanomeatal flap and two in the hypotympanum when entering the middle ear. The anatomy of the jugular bulb is considered, particularly in regard to its quite variable placement within the temporal bone. The manner of clinical presentation of the high jugular bulb and previous cases in the literature where the jugular bulb has been discovered in juxtaposition to the surgical approach are discussed. Implications of surgical management are considered.
Two cases of lateral sinus thrombosis presenting with extracranial head and neck abscesses

Published: November 2007

AbstractTwo cases of lateral sinus thrombosis in fit adults with no previous otological history are presented. One case occurred in association with Bezold's abscess and followed mastoiditis which was masked by previous antibiotic treatment. The other case occurred in association with an occipitoparietal scalp abscess and there was no obvious preceding middle ear infection. The causative bacteria were Streptococcus milleri and a variant Steptococcus intermedius. Lateral sinus thrombosis is discussed.

Published: November 2007

AbstractParapharyngeal space cysts, besides salivary gland origin may be derived from the first and dorsal portions of the second pharyngeal pouches. They are mucosal or epithelial lined structures with no external or visceral opening and always present on the lateral aspects of the nasopharyngeal wall.Two consecutive cases of parapharyngeal space cysts totally excised by transoral and transparotid routes are presented.
Myxoma of the larynx: a case report and a review of literature
Authors: Hadley J. , Gardiner Q. , Dilkes M. , Boyle M. 
Published: November 2007

AbstractLaryngeal myxomas are rare benign mesenchymal tumours in contrast to myxomatous degeneration in laryngeal polyps which occurs frequently. A correct diagnosis of myxoma is usually not difficult to reach if the possibility of myxomatous degeneration in laryngeal polyps is excluded and strict pathological criteria are adhered to. We report a myxoma arising from the left vocal fold in a 64-year-old male who presented with a four-year history of intermittent dysphonia. Although excision was microscopically incomplete, there is no evidence of recurrence macroscopically 18 months later and the patient remains asymptomatic.
