Recent reports indicate that the cochlear nerve may be absent in some cases of congenital sensorineural hearing loss. The aim of this prospective study was to determine the incidence of cochlear nerve anomaly in cochlear implant candidates with congenital hearing loss using magnetic resonance imaging (MRI). Twenty-seven patients with congenital profound bilateral sensorineural hearing loss who were being evaluated for the cochlear implant procedure were studied.

These patients had high-resolution computerized tomography (CT), through the petrous bone in axial sections. MRI examinations consisted of T1 and turbo spin echo (TSE) T2-weighted 3 mm axial images, and additional 3D Fourier Transform T2-weighted TSE sequences obtained on three different planes (axial, perpendicular and parallel to the internal auditory canal (IAC) i.e. oblique sagittal and coronal, respectively) for the purpose of cochlear nerve demonstration. Results showed that all of the 14 patients with normal CT of the temporal bone, had four distinct nerves in the distal part of the IAC on TSE-MRI. Thirteen patients demonstrated various bony malformations of the cochleovestibular system on CT. MRI revealed the absence of the cochleovestibular nerve in four patients where the IAC was very narrow or completely absent on CT. One patient with severe Mondini malformation who had an enlarged IAC demonstrated an isolated absent cochlear nerve.

The Bcl10 gene encodes a protein probably involved in some apoptotic regulatory pathways. Bcl10 mutations lead to the translation of truncated proteins that show gain-of-function transforming activity; it has been suggested thaBcl10 may represent a major target gene for inactivation in many human cancers. To define the frequency of Bcl10 mutations in laryngeal squamous cell carcinoma and their possible association with tumour progression, we investigated a large panel of tumours representative of all grades and stages of malignancy.

To detect pathogenic mutations in exons 1, 2 and 3 of the Bcl10 gene, we performed a silver-staining polymerase chain reaction – single-strand conformation polymorphism (PCR-SSCP) analysis followed by direct DNA sequencing. We revealed the presence of SSCP variants in 18 out of 91 laryngeal tumours. Direct DNA sequencing showed previously described polymorphisms but no pathogenic mutations. We have strong evidence that the Bcl10 gene is not involved in laryngeal carcinogenesis.

Two children aged three and seven years presented to the department of Otolaryngology with total dysphagia following the accidental swallowing of a steel ball bearing and a plastic ball. These rare spherical foreign bodies were removed successfully by oesophagoscopy under general anaesthesia using an innovative method involving a balloon angiographic catheter.

The objective of this study was to evaluate the safety, efficacy and acceptability to patients of day-case septorhinoplasty. Twenty-nine patients undergoing elective septorhinoplasty in a dedicated teaching hospital day-case unit were asked to complete day surgery questionnaires (DSQ) at six weeks post-operatively. Details of surgery performed, demographic data, readmission rates and complications were collected prospectively. No major complications were recorded. One patient had to be admitted for overnight observation following post-operative bleeding. The DSQ showed that the great majority of patients were satisfied from the day-case setting (satisfaction score 81). This preliminary study showed that day surgery septorhinoplasty was acceptable to the patient and was associated with a very low readmission rate. We believe that in carefully selected young healthy patients it is an acceptable alternative to an in-patient procedure.

Laryngeal manifestations of malignant sialogenic neoplasias are rare. This paper documents the clinical features, treatment, biological behaviour and prognosis of 15 cases of malignant sialogenic tumours of the larynx that were reviewed in a retrospective clinical and histopathological study. The 15 cases of malignant sialogenic tumours of the larynx were diagnosed at the University Hospital, Eppendorf, over a period of 33 years (1965–1998). Forty per cent were adenoid cystic carcinomas, 33 per cent mucoepidermoid carcinomas and 27 per cent were poorly differentiated adenocarcinomas. Local tumour resection, if necessary in combination with bilateral neck dissection and post-operative radiotherapy, was associated with a five-year survival rate in 80 per cent of the mucoepidermoid carcinoma cases. Adenoid cystic carcinoma was associated with a less favourable five-year survival rate of 33 per cent. Low-differentiated adenocarcinomas were associated with the least favourable prognosis with a five-year survival rate (25 per cent). The prognosis for these tumours is thus poorer than for squamous cell carcinomas with the same localization and TNM status.

One hundred and eight parotidectomies performed by a single consultant were reviewed. Eighty-five patients had primary parotid disease, 23 patients had extra-parotid primaries. Pleomorphic adenoma was the most common histological diagnosis. In patients with primary parotid disease, a post-operative temporary facial nerve palsy was noted in 15 patients, with a further four developing a permanent palsy. Patients with metastatic disease to the parotid had a poor prognosis.

Endoscopic laser treatment was performed in 43 patients with pre-malignant or malignant vocal fold epithelial lesions, 10 were treated with endoscopic laser surgery for dysplasia, 12 for carcinoma in situ (CIS), five for verrucous carcinoma and 16 patients for squamous cell carcinoma (SCC). Thirty-two patients received laser therapy as their first therapy, whereas 11 patients had had previous radiation therapy for laryngeal carcinoma (n = 9) or CIS (n = 2).

Recurrence after initial laser therapy necessitating re-treatment (a second laser treatment or radiotherapy) occurred in nine out of 32 patients (28 per cent), thus 23 (72 per cent) were maintained free of disease during the follow-up period.

Besides the 32 patients without previous therapy, patients who had already undergone radiat on therapy were also included in this study. In this group there were nine patients with SCC, one patient with CIS and one with dysplasia. They all underwent laser therapy. Four were free ofdisease during follow-up (36 per cent) and seven developed recurrences. Six (58 per cent of allpatients with previous radiation therapy) underwent total laryngectomy.

Laryngeal photographs from 165 Taiwanese subjects were taken during microlaryngoscopy. Photographs of the vocal fold during the open phase were chosen. For measuring the vocal fold length, both the photograph of a ruler and the larynx were taken under the operating microscope, thus forming a ‘new scale’. Photographs of the vocal fold and the ruler were then processed at the same power of magnification. The length of the vocal folds was measured with the ‘new scale’. In 100 patients receivingdirect laryngoscopy under neuroleptic anaesthesia, the vocal fold length was 14.6 ± 1.2 mm (n = 35) for males and 11.1 ± 1.0 mm (n = 65) for females. In 65 patients under general anaesthesia, the vocal fold length was 15.3 ± 1.6 mm (n = 23) for males and 13.5 ± 1.3 mm (n = 42) for females. Statistical analysis revealed a significant difference between both groups and both sexes. Elongation of the vocal fold under general rather than neuroleptic anaesthesia may be important when performing functional surgery of the vocal fold.

The case of a 17-year-old girl who presented with a two-day history of absolute dysphagia secondary to a bulbar palsy due to a pre-pontine abscess is described. Rigid oesophagoscopy was normal and a neurology consultation suggested a central cause for her dysphagia. However the diagnosis was delayed because a computed tomography (CT) scan of her brain and brainstem was reported as normal. A subsequent magnetic resonance image (MRI) scan revealed a pre-pontine abscess. CT scanning is not as reliable as MRI in the diagnosis of infective lesions of the brainstem/brain, especially early in the course of the infection.

Pneumocystis carinii is an opportunistic infection found in patients with impaired immunity. Under favourable conditions the parasite can spread via the blood stream or lymphatic vessels and cause extrapulmonary dissemination. We report a case of P carinii infection presenting as bilateral aural polyps, otitis media and mastoiditis in human immunodeficiency (HIV)-positive patient with no history of prior or concomitant P carinii infection.

Percutaneous tracheostomy is a procedure frequently carried out in a critical care setting. It is performed in the majority of cases by anaesthetists in the United Kingdom. The ENT surgeon is only called in situations where it is deemed by the intensivist that percutanous tracheostomy would prove too great a risk. In this situation the patient was taken to the operating theatre for a surgical tracheostomy. In our paper, a retrospective analysis was performed of all percutaneous tracheostomies carried out by ENT surgeons in the Royal Glamorgan Hospital, during a two-year period from July 1999 to July 2001, to assess whether percutaneous tracheostomy is a feasible option as a first line procedure in all elective tracheostomies. Thirty-six patients were included in the study. The mean age was 60.2 years. Haemorrhage was noted to be a problem in only one patient and two patients developed post-operative wound infection that was treated with systemic antibiotics. No other complications were encountered. We propose that all ENT surgeons should be trained in performing percutaneous tracheostomy and that it should be used as the gold standard in elective tracheostomy insertion. In cases where difficulties are likely to be anticipated, percutaneous tracheostomy can still be considered as the first option. This can be performed in the operating theatre setting with the knowledge that if any complication should occur then conversion to surgical tracheostomy can be done without delay.

Airway invasion is a life-threatening complication of thyroid cancer. An important issue that deserves better attention is the differentiation between the clinical features of tracheal wall invasion versus those of an obstructive endotracheal lesion. We present information on the clinical course, diagnostic modalities utilized, management instituted, along with the prognosis, and follow-up data on a group of patients presenting with obstructive endotracheal lesions of thyroid cancer. Two thousand four hundred and eighty-nine thyroid cancer patients were seen at our institution from December 1975 to May 2000. Thirteen patients presented with symptoms of respiratory distress related to obstructive endotracheal lesions. At presentation, 11 patients underwent endoscopic examination. Imaging studies consisting of I123 whole body scan (WBS), computed tomography/magnetic resonance imaging (CT/MRI) of neck and chest, whole body positron emission tomography using 18-fluoro-2-deoxy-D-glucose (FDGPET) were done, as also was determination of the tumour markers, serum thyroglobulin (TG) and calcitonin. Patients were followed for one to 108 months after the initial presentation. Intraluminal tracheal obstruction was severe in eight patients; five had near-total-occlusion. Paralysis of the vocal folds was present in five. Evidence of metastatic disease was present in most patients. Dissociation between iodine uptake and TG synthesis was evident in five patients during follow-up. Four patients died of cancer. Of the nine living patients; cancer persisted in six, recurred in two patients, and remitted in one. This study has identified obstructive endotracheal lesion of thyroid cancer as a distinct entity apart from tracheal wall disease. These data provide evidence that intraluminal tracheal invasion of thyroid cancer is an ominous sign and a frequent cause of morbidity.

A 53-year-old female presented with a painful swelling within her external auditory meatus. Biopsies revealed this to be a B-cell lymphoma and she underwent surgical treatment followed by chemotherapy. This is the first reported case of non-Hodgkin’s lymphoma of the external auditory meatus in an human immunodeficiency virus (HIV)-negative patient.

Consanguineous marriage is a tradition which is commonly practised among Asian, African, and Latin American communities whether they are living in their own countries or settled in Europe or the USA.

These communities, in addition to their custom of interrelated marriage, have large families and are a rapidly growing population. The siblings of consanguineous marriages have a significantly higher incidence of autosomal recessive diseases including hearing impairment.

Two epidemiological surveys were carried out 10 years apart. There were 6 421 subjects from Riyadh City and 9 540 from all other parts of the Kingdom of Saudi Arabia. A random sample was examined otologically and a questionnaire was filled in that included age, sex, family relation, number of siblings, etc. ENT examination and audiological assessment were performed. Consanguinity was found among 22 per cent as first cousins and 23 per cent as second cousins in the first survey. In the second survey 19 per cent were first cousins and 28 per cent second cousins. The rate of consanguinity was 45 per cent in the first survey and 47 per cent in the second. The prevalence of hereditary sensorineural hearing loss (SNHL) was 66.07 per cent and 36.6 per cent in the first and second survey respectively.

The incidence of hereditary hearing impairment is very high in developing countries compared to developed countries. Prevention is essential to reduce the incidence of genetic hearing loss. Consanguinity should be discouraged through health education of the public about the adverse effect of interrelated marriage. Genetic counselling, premarital and antenatal screening are to be applied whenever possible, at least for those at risk of developing genetic diseases including hearing impairment.

This study was performed to find out the effectiveness of three different treatments of patients having acute tonsillopharyngitis. Three groups of patients were selected (50 patients in each group). Group I received one antibiotic according to the result of culture and sensitivity test, while groups II and III received two antibiotics or one antibiotic respectively without a culture and sensitivity test. Diagnosis was based on the acutely subjective symptoms of sore throat and positive clinical examination findings. The effectiveness of treatment in group I (96 per cent) was statistically significant (p<0.05) and higher than group II (82 per cent) and group III (74 per cent), while the difference between group II and III was not statistically significant (p>0.05).

Our findings demonstrate that a culture and sensitivity test of the throat swab is necessary before treating acute tonsillopharyngitis. It was suggested that there should be appropriate selection of antibiotics to preserve normal flora, avoidance antibiotics for viral infections, patient compliance with prescription and educational programmes directed at patients and physicians. All of these measures would assist in reducing the volume of antibiotic use, bacterial resistance and the overall cost of treatment of tonsillopharyngitis.

Forty children (age group four to 12 years) undergoing adenoidectomy and/or tonsillectomy were subjected to pre- and post-operative polysomnography. Thorough clinical evaluation and X-ray soft tissue nasopharynx lateral view was carried out for all the patients. The tonsils were clinically graded from grade I to IV, whereas the adenoids were measured radiographically (using three different measurements) in all children. Thirty out of 40 (75 per cent) children presented with predominant obstructive symptoms, out of whom 22 (73.3 per cent) were found to have obstructive sleep apnoea (OSA), i.e. apnoea index > five per hour. The remaining 10 (25 per cent) had predominantly inflammatory symptoms on presentation and out of these two (20 per cent) were found to have OSA. Relative adenoid size expressed as a ratio between the distance from the point of maximum thickness of adenoids along a line drawn along a straight part of the basiocciput and distance from the posterior nasal spine to the antero-inferior edge of the spheno-basioccipital synchondrosis, was found to have a highly significant correlation with the grade of OSA. In our study, all patients with this ratio greater than 0.64 were found to have OSA. No correlation between tonsil size and grade of OSA was found. There was a highly significant improvement in polysomnographic scores following surgery in all patients.

Tonsillectomy has been performed by a number of techniques. This double blind randomizedcontrolled study compares the technique of tissue coblation with bipolar dissection for the removal of tonsils in 10 adult patients with a history of chronic tonsillitis. A significant reduction in post-operative pain and more rapid healing of the tonsillar fossae were found in the side removed by tissue coblation. There were no episodes of primary or secondary haemorrhage on either side. This new technique for tonsil removal warrants further study.

Pain following tonsillectomy in children is a significant problem that tends to be underestimated. We audited post-operative pain in 33 children and found significant proportions of children in moderately severe to severe pain, particularly at, or soon after returning to the ward. These findings led to changes in practice that included the administration of pre-operative paracetamol and diclofenac as well as the uniform post-operative prescription of them, with printed instructions to reduce the scope for mistakes by medical staff. Other changes included a uniform policy, with which the nursing staff could become familiar, and the regular formal recording of pain to assist in the recognition of pain and analgesic requirements. On re-auditing two years later, in a group of 100 children, post-operative pain was significantly improved. The proportion experiencing moderately severe to severe pain on returning to the ward, as their maximum pain score and pain score at discharge fell from 70 per cent to 48 per cent, 85 per cent to 56 per cent, and six per cent to two per cent respectively.

Isotonic saline solution is frequently used in nasal and tracheal lavage. In a previous clinical study, it was found that Ringer-Lactate solution, as a nasal lavage, was better for mucociliary clearance function than isotonic saline solution after nasal septal surgery. In this experimental study, the effects of Ringer-Lactate and isotonic saline solutions on mucociliary clearance of healthy rat tracheal epithelium were investigated by measuring the transport of carbon particles. We found that tracheal segments that were irrigated with Ringer-Lactate had better mucociliary transport than those irrigated with isotonic saline (p = 0.035).

We report the use of nebulised adrenaline in the treatment of secondary oropharyngeal haemorrhage. Cases involving two adults and one child are presented to illustrate the usefulness of this technique in helping to achieve haemostasis without the need for a general anaesthetic. The mechanisms of the haemostatic action of adrenaline are also explored. We believe that in selected cases nebulised adrenaline is both safe, effective and easily tolerated and represents a useful additional tool in the treatment of oropharyngeal haemorrhage.
