Objective: To investigate the incidence and clinical significance of deranged clotting results among patients with juvenile (nasopharyngeal) angiofibroma.

Methods: Twenty consecutive patients treated for juvenile angiofibroma between March 1998 and July 2002 in whom preoperative coagulation tests were performed were selected. Results were compared with normal laboratory values, and clinical and histological records were retrospectively analysed.

Results: Four out of 20 patients were found to have abnormal tests, consistent with concurrent consumptive coagulopathies. One patient was found to have a raised D-dimer level. This resolved following removal of the lesion.

Conclusions:The association between larger arterio-venous malformations and disseminated intravascular coagulopathy is well described (Kasabach–Merritt syndrome). Our findings suggest that low-grade consumptive coagulopathies may also complicate smaller juvenile angiofibromas, implying that preoperative coagulation screening tests may have a role in ensuring optimal perioperative haemostasis.

Ear candles are hollow tubes coated in wax which are inserted into patients’ ears and then lit at the far end. The procedure is used as a complementary therapy for a wide range of conditions. A critical assessment of the evidence shows that its mode of action is implausible and demonstrably wrong. There are no data to suggest that it is effective for any condition. Furthermore, ear candles havebeen associated with ear injuries. The inescapable conclusion is that ear candles do more harm than good. Their use should be discouraged.

Laryngeal trauma is an uncommon injury. This has made it difficult for a common management pathway to evolve and controversies remain. Methods of airway control, usage of investigations and the role of stents or plates in surgical management are reviewed. It is important not to delay treatment due to the poor voice and airway outcome of chronic laryngeal stenosis.

Retropharyngeal abscess (RPA) is an uncommon condition with the potential for significant morbidity and mortality if not detected early. The authors present a case report of a 19-month-old child who presented with the common clinical features of a retropharyngeal abscess and in whom the diagnosis was not established by examination and ultrasonography. This led to a delay in appropriate management until a computed tomography (CT) scan was performed under general anaesthesia. The scan demonstrated the diagnosis and surgical drainage was performed under the same anaesthetic. The child subsequently made a complete recovery. The investigation and treatment of RPAs is a matter of some debate and the authors review the recent literature to determine the best management strategy.

Sixty-eight patients who presented with glottic and glottosupraglottic squamous cell carcinoma and who were managed in this department with supracricoid partial laryngectomy (SCPL) with either cricohyoidoepiglottopexy (CHEP) or cricohyoidopexy (CHP), were retrospectively reviewed. The authors analysed the functional and oncological results of the patients. The median follow-up period was 62 months. The average times until decannulation and nasogastric feeding tube removal were 27.7 and 26.4 days, respectively. All patients were successfully decannulated. All patients were able to swallow, but one patient was unable to swallow and had recurrent aspiration. Better functional results were achieved in patients managed with CHEP procedure than the patients managed with CHP procedure. The five-year absolute and cause-specific actuarial survival rates (Kaplan-Meier method) were 78.6 per cent and 93.9 per cent, respectively. The five-year actuarial local control and nodal control rates were 89.5 per cent and 90.4 per cent, respectively. Local recurrence was statistically more likely in patients with positive resection margins (p <0.006). Overall, local control and laryngeal preservation were achieved in 95.6 per cent and 89.7 per cent, respectively. Supracricoid partial laryngectomy procedures (CHEP and CHP) are possible alternatives to total laryngectomy in the treatment of selected advanced glottic and glottosupraglottic carcinomas.

Tinnitus, that is defined as ’ringing in the ear’, is and has probably always been a very common phenomenon in the health history of mankind. A variety of pathomechanisms for its onset has been proposed in the past and this trend sees no stopping. Precise pathomechanisms still remain unclear. From the historical point of view, tinnitus is a very interesting topic but there is a lack of scientific enquiries. As its earliest historic reference, the Papyrus Ebers is often cited. By reviewing the original source, however, it is very unlikely that this contains the earliest historic reference of tinnitus. It is rather likely indeed that tinnitus was a known symptom in the ancient Egypt but it has never been exclusively been written down. This article reviews data provided by this fascinating historical period on the questionable reference and highlights the impact of history on the modern status of tinnitus.

Nasal inspiration is important for maintaining the internal milieu of the lung, since ambient air is conditioned to nearly alveolar conditions (body temperature and fullysaturated with water vapour) upon reaching the nasopharynx. This literature review of the existing in vivo, in vitro and computational studies on transport phenomena that take place within the human nasal cavity summarizes the current knowledge on air-conditioning characteristics of the human nose.

Vertigo is caused by unilateral vestibular dysfunction. Unilateral vestibular dysfunction represents either vestibular overactivity as benign positional vertigo or underactivity as in labyrinthitis or both, at different times, as in a Ménière's attack. Unilateral dysfunction could also be central rather than peripheral, such as in a lateral medullary syndrome. Unilateral vestibular dysfunction could affect any of the five different sensory areas in the labyrinth, the three semicircular canals and the two otoliths, or their brainstem connections. For rigorous diagnosis of the cause of vertigo, ideally one would have robust, reproducible, quantitative vestibular function tests sensitive to dysfunction of each of the five sensory regions in each ear. In working towards this ideal we have, over the last 15 years, developed three new vestibular function tests: (1) impulsive tests of individual semicircular canal function, (2) evoked potential tests of saccular function and (3) subjective visual horizontal tests of utricular function. The physiological rationale of these three tests is reviewed as well as the interpretation of their results in various diseases.

This study seeks to define the most appropriate guidelines for selection of patients for magnetic resonance imaging (MRI) to exclude a vestibular schwannoma. Improved selection may reduce patient anxiety and improve resource utilization.

All MRIs of the internal auditory meatus, performed during the year 2000, were reviewed. Audiograms and symptoms were collated for all ’positive’ scans and 100 negative scans. Information was analysed using seven published protocols and other defined frequency specific criteria.

A diagnosis of vestibular schwannoma was made on 36 scans. Four criteria had a sensitivity of >95 per cent; of these the highest specificity (49 per cent) utilized an interaural difference at two adjacent frequencies of 15.dB in unilateral hearing loss and 20.dB in bilateral asymmetric loss.

Applying our best protocol would have reduced the number of scans performed from 392 to 168. The one patient with a vestibular schwannoma who was excluded had trigeminal paraesthesia, an independent indication for investigation.

Patients with chronic otitis media (COM) may have profound sensorineural hearing loss either due to the disease process or secondary to a surgical procedure. Some patients who are candidates for cochlear implantation may have COM coincidentally. The patients in this group need special attention when cochlear implantation is applied. The aim of this study is to evaluate the potential risks and complications in patients with COM.

Cochlear implantation was performed in six patients with COM or an infected radical cavity and profound hearing loss. Five of them underwent a two-stage operation, and one had a single-stage operation. Cochlear implantation was performed in all patients without complications. The follow-up period was uneventful.

Although such patients have some potential risks, when certain surgical rules are followed very strictly cochlear implantation can be successfully performed in patients with COM.

Chemical perfusion of the inner ear is an increasingly popular treatment for Ménière’s disease. The authors report on the long-term results of 22 patients treated with gentamicin delivered via a round window micro-catheter. Patients with Ménière’s disease underwent continuous, low dose (10 mg/ml) gentamicin infusion at 5 microlitre per hour for 10 days, through a micro-catheter placed into the round window niche. Vertigo was controlled in 95 per cent, whilst preserving hearing in 77 per cent. Hearing improved in three patients. Three patients with pre-operative serviceable hearing (PTA < 50 db) demonstrated reduced hearing; two patients with pre-operative non-serviceable hearing developed a dead ear. Tinnitus and aural fullness remained unchanged or improved in 86 per cent and 68 per cent respectively. Long-term vertigo control can be achieved using low dose gentamicin, whilst preserving hearing and vestibular function in the majority of patients. This procedure appears to stabilize the vestibular function, enhancing the chance of effective vestibular rehabilitation.

Defects in the system controlling the cell cycle can lead to an increased proliferation of cancer cells. The aim of this study was to analyse the immunohistochemical expression of chosen cell cycle proteins (P16, cyclin D1 and retinoblastoma protein) and their connection with the clinical course of the disease in laryngeal squamous cell cancer (LSCC). Cancer tissue sections obtained from 58 patients after total laryngectomy served to determine the level of the proteins’ expression using immunohistochemical staining and commercial antibodies. A decreased level of P16 expression in 47 per cent, of retinoblastoma protein in 12 per cent and strong cyclin D1 expression in 48 per cent of cases was revealed. Our results show significant correlation between decreased P16 expression and increased tumour dedifferentiation. Overexpression of cyclin D1 was statistically more common in locally advanced tumours (T3–T4). Low expression of retinoblastoma protein was significantly correlated with both positive P16 immunostaining and with strong cyclin D1 expression. Our study confirms that dysfunction of cell cycle regulation is a common event and may play a significant role in the development of squamous cell carcinoma of the larynx.
