Craniofacial fibrous dysplasia.

Fibrous dysplasia is a benign localized bone disorder of unknown aetiology in which endocrinopathies, abnormal pigmentation of the skin and mucous membranes may form part of the disease. Five cases involving the facial and cranial bones are described to illustrate the various presentations and radiological appearances including computerized tomography and magnetic resonance imaging. Some of these cases demonstrate that serial radiology may be adequate for diagnosis and management without the necessity for histological confirmation. The place of limited surgical treatment for the craniofacial sites is debated.

Information leaflets in the rhinitis clinic?

Failure to get relief from topical steroid nasal spray is often blamed on poor administration knowledge. In a population of patients referred to the rhinitis clinic who have failed to get relief from topical steroid nasal spray when prescribed by the general practitioner, lack of patient education only accounts for 28 per cent of patient treatment failures and other factors e.g. poor compliance, erroneous diagnosis or severity of rhinitis will be responsible for the rest. Information leaflets are considered to be a good idea by nearly all patients but this study demonstrates that they would only be of therapeutic benefit to a minority of patients.

Chronic sinusitis and the yellow nail syndrome.

Diagnosing syndromes that include chronic sinusitis can expedite the management of both conditions. Yellow nail syndrome is usually described as the combination of yellow nails, lymphoedema and often respiratory manifestations such as chronic sinusitis, bronchiectasis and pleural effusions. The pathology responsible for the syndrome is believed to be lymphatic hypoplasia. Diagnosis of yellow nail syndrome is clinical not requiring any specialized tests. In the two cases described, the respiratory tract manifestations required the most active investigation and management. The significance of this syndrome to the otolaryngologist is discussed.

Management of acquired tracheo-oesophageal fistula following intubation.

The management of acquired tracheo-oesophageal fistula due to tracheal intubation is reviewed and a case complicated by left vocal cord palsy and subglottic stenosis is presented. Permanent cricothyroidostomy was used in the management of this original triad of complications.

Aberrant central venous catheter complicating radical neck dissection.

Abnormal migration of central venous catheters is especially common in the case of long lines inserted via the antecubital fossa. A case is described of internal jugular vein migration of a central venous catheter complicating an ipsilateral radical neck dissection.

The acceptability of secondary tracheo-oesophageal fistula creation in long standing laryngectomees.

The use of a tracheo-oesophageal voice prosthesis was introduced to the Glasgow Royal Infirmary Otolaryngology, Head and Neck Surgery unit in 1986. Although it was the authors' impression that most total laryngectomees since then had been offered this method of voice restoration, it was thought that long standing laryngectomees were seldom offered tracheo-oesophageal fistula (TOF) speech. Therefore all 58 total laryngectomees currently attending the combined head and neck surgery/radiotherapy clinic were assessed. Thirty-two had a tracheo-oesophageal fistula with voice prosthesis. All of these patients had undergone their total laryngectomy since 1986 and 83 per cent had achieved TOF speech. The remaining 26 patients (who mostly had their laryngectomy before 1986) had not been offered TOF speech. An outpatient consultation was arranged for these patients and 63 per cent of those offered, accepted TOF creation and a voice prosthesis. When compared to those who refused, it was found that good oesophageal speech, age or interval since laryngectomy were not good predictors of likely refusal. This study indicates that all fit long standing laryngectomees should be offered secondary TOF creation.

Sleep nasendoscopy: what benefit to the management of snorers?

It has been proposed that sleep nasendoscopy (SN) will improve the success rate of the uvulopalatopharyngoplasty operation by identifying those patients with palatal snoring. The aim of this study was to test the efficacy of SN in the management of snorers who do not have obstructive sleep apnoea. This study compared a group of 26 snorers managed without SN (group A) to a group of 27 snorers managed with SN (group B). The post-operative results of group A were 61 per cent cured, 27 per cent better and 8 per cent unchanged. Group B results were 76 per cent cured, 19 per cent better and 5 per cent unchanged. However, if patients with only palatal snoring had surgery, the results for group B would have been 94 per cent cured, 6 per cent better and 0 per cent unchanged (95 per cent C.I. of difference +0.14, +0.54, p = 0.017). The results confirm the predictive power of SN in identifying success following uvulopalatopharyngoplasty. A simple grading system is suggested to aid in treatment planning. Patients are divided into three categories on SN: palatal snorers, mixed snorers and non-palatal (tongue base) snorers. It is proposed that uvulopalatopharyngoplasty may cure palatal snorers but mixed snorers will need additional therapies to eliminate their snoring although uvulopalatopharyngoplasty may improve the symptoms.

Adult obstructive sleep apnoea syndrome and tonsillectomy.

A surgical cure for adult obstructive sleep apnoea syndrome (OSAS) is an attractive alternative to nasal continuous positive airway pressure, but current research suggests that uvulopalatopharyngoplasty is not effective in all patients. No subgroup of these patients, who might benefit from surgery to the oropharynx, has as yet been identified. In this study we examined the results of tonsillectomy either as an isolated procedure or as part of uvulopalatopharyngoplasty in seven patients, who had tonsillomegaly. In all seven there was a short-term improvement between the pre-operative and post-operative apnoea/hypoapnoea (A/H) index (100-65 per cent), which could not be accounted for by change in the body mass index (BMI). In one patient a diagnosis of Non-Hodgkin's lymphoma was made from histological examination of the tonsils. The results suggest that adult patients with tonsillomegaly may represent a subgroup of patients with OSAS, who would benefit from surgery aimed at the oropharynx.

Cavernous sinus thrombosis following manipulation of fractured nasal bones.

Septic cavernous sinus thrombosis is a serious infective condition with a high mortality and morbidity. We report the first case to our knowledge of septic cavernous sinus thrombosis following manipulation of fractured nasal bone under general anaesthesia. The patient later developed complications of pneumonia with pleural effusion, a vegetative lesion of the mitral valve, and blindness.

Portable method for the determination of snoring site by sound analysis.

It has been shown that computerized sound frequency analysis can be used to distinguish between different snoring sites. The aim of this study was to investigate whether a portable recording method using audiotapes and digital minidisc formats could produce waveforms similar to a computer recording. The snores of 12 subjects in their natural sleep were recorded onto audiotape, minidisc and directly onto a computer. For each snorer and recording method 30 snore samples were analysed and their power ratio was calculated indicating the relative amount of sound below and above a set frequency. It was found that the power ratios from audiotape recordings were significantly different to those from computer recordings for all snoring sites (p = 0.0007), whereas there was no significant difference between minidisc and computer recordings (p = 0.41). These results indicate that it would be possible to base a portable snore analysis system for site determination on minidisc, but not on audiotape recordings.

Primary tumours of the vestibule and inner ear.

Seven primary tumours of the vestibule and inner ear are described, six schwannomas and one traumatic fibroma. Schwannomas in this situation may occur as sporadic tumours, or may be a feature of neurofibromatosis type 2 (NF-2). In the latter condition they may occur in isolation or in association with, but separate from, schwannomas arising in the internal meatus. Direct extension into the vestibule of an intrameatal vestibular schwannoma is well reported, but extension of an intravestibular tumour into the internal meatus is not described. Traumatic fibromas of the vestibule are rare and the trigger could be an attack of labyrinthitis. Intravestibular tumours, although rare, are likely to be diagnosed with increasing frequency with the widespread use of MR imaging.

Cochlear implantation following temporal bone fracture.

Seven cases of profound hearing impairment following either unilateral or bilateral temporal bone fracture are presented who were implanted with the Nucleus 22 channel or Ineraid devices. Six patients suffered bilateral temporal bone fractures. One patient had prior congenital unilateral profound hearing impairment. This patient suffered a unilateral temporal bone fracture. Six patients became regular users of their implants. One gained little benefit and became a non-user. Two of the regular users experienced facial nerve stimulation, which could not be programmed out. In these two cases the implant was removed and the contralateral ear successfully implanted. Implant-aided audiometry demonstrated a hearing threshold of 40-50 dB at nine months after switch-on. The reliability of computed tomography (CT) scanning in predicting cochlear patency in cases of temporal bone fracture will be discussed. The benefit of complimentary imaging with magnetic resonance (MR) is highlighted.

ENT open access clinic: an audit of a new service.

Ear, nose and throat emergencies constitute a heavy but unpredictable workload for the junior otolaryngologist. Patients are often seen in the treatment room on the ward or in the casualty department. Many patients referred as emergencies can in fact be seen the following day without detriment. This audit examined the change in treatment room workload when an open access ENT clinic was set up each weekday morning. The results demonstrate that around 75 per cent of the patients seen were suitable for waiting until the next day. The clinic was considered a success as it provided benefits for GP access, routine clinics, junior doctor teaching and concentration of aural toilet cases under expert nurse care.

Is Blu-tack as effective at attenuating sound as over-the-counter ear plugs?

OBJECTIVE: To demonstrate that Blu-tack is equally effective at attenuating sound as over-the-counter ear plugs. METHODS: Nineteen healthy volunteers had their hearing thresholds assessed before and after the insertion of over-the-counter ear plugs. The results were compared with hearing thresholds following the insertion of Blu-tack. Thresholds were tested at: 0.5, 1, 2, 3, 4, 6 and 8 kHz. The differences were compared, and p values of less than 0.02 were regarded as significant. Using a visual analogue scale, volunteers were asked to assess the comfort and ease of insertion of the ear plugs and Blu-tack, and their peace of mind whilst using the ear plugs and Blu-tack. RESULTS: Blu-tack was less effective at attenuating sound at low frequencies, but was as effective as over-the-counter ear plugs at attenuating sound above 3 kHz. Blu-tack was significantly more comfortable to wear (p = 0.006). There was no difference in terms of ease of insertion and peace of mind. CONCLUSION: Blu-tack can be regarded as a comfortable alternative to over-the-counter ear plugs for the attenuation of everyday sound.

Prognostic value of electrocochleography in patients with unilateral Menière's disease undergoing saccus surgery.

Although a controversial operation, saccus surgery has continued to be used in patients with severe Menière's disease in whom hearing preservation is the objective. The aim of this study was to determine if electrocochleography (ECoG) could predict the patients who would be free of vertigo, 2 and 5 years after surgery. Seventy patients with severe Menière's syndrome underwent ECoG prior to endolymphatic sac surgery. Eighty-four per cent of the patients had an abnormal electrocochleogram. The patients were interviewed 2 and 5 years after surgery. At 2 years, 4/10 (40%) patients with normal ECoG were relieved of dizziness compared to 38/51 (75%) with abnormal ECoG (P < 0.05). At 5 years, 5/8 (63%) patients with normal ECoG were relieved of dizziness compared to 30/30 (100%) with abnormal ECoG (P < 0.001). The patients with a normal ECoG do have less severe measurable hearing impairment (P < 0.05) although they are more likely (P < 0.05) to complain of constant tinnitus. Their history of dizziness is longer and their dizziness more disabling before surgery. In conclusion, patients with a normal ECoG will be less likely to benefit from saccus surgery in the first 5 years. These patients may represent a different nosological entity.

Chronic otitis media and ankylosing spondylitis: an HLA association?

A prospective study was undertaken to investigate an apparent correlation between ankylosing spondylitis (AS) and the incidence of otological conditions. 42 consecutive patients attending the ankylosing spondylitis clinic were examined otoscopically and had audiometric assessment. 19% of the patients (8/42) had active or inactive chronic otitis media. The prevalence of chronic otitis media in this group was significantly greater (P less than 0.01) than a stratified sample of the general population from the Medical Research Council Institute of Hearing Research National Study of Hearing, controlled for age, sex and socio-economic group, where the expected incidence was 5%. A hypothetical explanation for the association is given and the need for HLA studies into chronic otitis media is discussed.

The effect of recurrent tonsillitis and tonsillectomy on growth in childhood.

The aim of this study was to determine if children with recurrent tonsillitis are smaller than expected before tonsillectomy and if they have an altered height or weight gain 1 year post-operatively. All (204) children attending the hospital for tonsillectomy with or without adenoidectomy had their height and weight measured pre-operatively and 1 year after operation. The results of 2204 children in local schools were used as a control population. Analysis was by comparison of each population with the Tanner charts. This study suggests that our population of children listed for tonsillectomy were not lighter or smaller than expected before operation but that one year after tonsillectomy, there was an increase in their weight gain. The height gain was no different than expected after operation. Overweight seems to be a medium term complication of tonsillectomy. It may be necessary to redefine the indications for tonsillectomy in children who are already obese.

Needlestick injury in surgeons: what is the incidence?

A prospective study by questionnaire was carried out to investigate the incidence of needlestick injury in the operating theatre staff of a teaching hospital and to calculate the individual risk of acquiring blood-borne virus infection in the UK from this source. The individual rate of needlestick injury in operating theatre staff was 1.55% per surgeon per operation (confidence interval (Cl) 0.6-2.5%). The calculated rate of clinical hepatitis B in surgeons compared with the observed rate suggests that needlestick in theatre is the main mode of transmission.

Chronic otitis media: a new extra-articular manifestation in ankylosing spondylitis?

Following a study reporting a fourfold increase in the occurrence of chronic otitis media in patients with ankylosing spondylitis, this prospective study examines this association with respect to severity, duration of disease, and acute phase in ankylosing spondylitis. Forty two consecutive patients with classical ankylosing spondylitis seen at the rheumatology clinic of a teaching hospital where the features of ankylosing spondylitis were recorded had an otological examination by an otolaryngologist. The occurrence of chronic otitis media (all categories) was 12/42 (29%). The acute phase serum markers (C reactive protein and IgG) were increased in patients with active or inactive chronic otitis media. Extra-articular manifestations were significantly more common in the chronic otitis media group than in those with no history of chronic otitis media. The results of this study suggest that chronic otitis media may be another extra-articular manifestation of ankylosing spondylitis. Alternative explanations, however, include similar aetiological factors for the two conditions or a previously unrecognised increased occurrence of HLA-B27 in patients with chronic otitis media.
