Sino nasal assessment questionnaire, a patient focused, rhinosinusitis specific outcome measure.
It is becoming increasingly important for clinicians to be able to demonstrate the effectiveness of their interventions. We have developed a rhinosinusitis--specific outcome measure (SNAQ-11) that avoids the shortcomings of the existing tools. This paper compares its use with the widely used Sinonasal Outcome Test (SNOT-20). We carried out a prospective study that involved forty patients undergoing endoscopic sinus surgery. Their SNAQ-11 and SNOT-20 scores were compared pre and post operatively. We also recorded individual symptom scores pre and post operatively in order to study the impact of surgery. The study shows a larger change in the postoperative SNAQ score compared to that in SNOT-20 (21% c.f. 11%) Although the pre and post-op changes in SNOT-20 are significant at the p = 0.005 level, the changes in the SNAQ-11 are highly significant at the p = 0.0001 level. Furthermore we have statistically confirmed that the change seen with SNAQ-11 is larger in relation to the variation in change as compared with SNOT-20 (-1.08 c.f. -0.59). Our results show that SNAQ-11 is a valid and highly relevant rhinosinusitis outcome tool. The results also confirm that Endoscopic Sinus Surgery seems especially effective at addressing nasal obstruction, congestion and facial pain/pressure, fair at anterior nasal discharge, sneezing, hyposmia and sleep disturbance and poor for post nasal drip, cough and earache.
Guidelines for the grading of tinnitus severity: the results of a working group commissioned by the British Association of Otolaryngologists, Head and Neck Surgeons, 1999.
Tinnitus is a common experience with up to one third of the adult population experiencing it at some time in their life. Less than 1% of the adult population have tinnitus of sufficient severity to affect their quality of life seriously (although up to 8% may seek medical advice about it). Much of the severity of tinnitus relates to the individuals' psychological response to the abnormal tinnitus signal. The prevalence of tinnitus increases in association with high frequency hearing loss. There is, unfortunately, no diagnostic test that either confirms the presence of tinnitus or its severity. Currently there is no satisfactory severity grading system. A five-point severity grading scheme is therefore proposed and the entry criteria detailed. The five severity points are: slight, mild, moderate, severe and catastrophic. Categorization as 'severe' or 'catastrophic' should be, by epidemiological definition, very rare. General guidance, theory and evidential support are contained within.

Partial resection of the middle turbinate at functional endoscopic sinus surgery.
The middle turbinate is often carefully preserved at Functional Endoscopic Sinus Surgery (FESS). However there is no clear understanding of its importance and its presence may prevent good access to the middle meatus to the detriment of the surgical result. In addition its bulk may cause symptoms of nasal obstruction and prevent paranasal sinus drainage. Adhesions and stenosis have been reported at the middle meatus following its preservation. We undertook a prospective study of 50 consecutive patients all of whom underwent resection of the anterior half of the middle turbinate at the time of Functional Endoscopic Sinus Surgery. The patients were asked to complete a symptom score sheet before and ten weeks after surgery. The parameters considered were nasal obstruction, nasal congestion, discharge, facial pain and headache. Non parametric analysis of the results indicated a significant improvement in all patient symptom scores and no postoperative complications were noted. We conclude that partial resection of the middle turbinate is a useful modification of accepted endoscopic sinus surgery techniques.
Ecchymoses may have been due to extracapsular haemorrhage from parathyroid adenoma.

Extracapsular haemorrhage from a parathyroid adenoma presenting as a massive cervical haematoma.
Spontaneous massive haemorrhage from a parathyroid adenoma is rare. It can cause extensive cervical ecchymosis as well as compression of structures within the neck. We present a case, discuss the diagnostic features and review the literature.
Establishing a new ENT-head and neck clinic.
We report our experience of the first fourteen months of a new head and neck surgical clinic established at a district general hospital. The structure of the clinic together with analysis of the patient case mix and referral patterns are considered. The perceived benefits include rapid patient access to specialist management, the development of subspecialty skills and excellent training opportunities for trainee registrars.

Clinical photographs as teaching aids: how reliable are they?
A study to investigate the value and reliability of clinical photographs as teaching aids was undertaken. Twenty colour photographs were taken using the StarMed video-otoscopic system. The pictures, which were a mixture of normal and abnormal ears, were shown to 21 experienced otolaryngologists from the UK and Canada. These clinicians were asked to identify the abnormality if any. The median score for correctly identified pictures was 15 (range 12-18). This score was identical for both the UK and Canadian subgroups. Although the abnormalities were consistently well recognized with an average correct identification rate of 90 per cent (range 67-100 per cent), the 'normals' were recognized significantly less well at only 41 per cent (range 5-71 per cent) (chi-squared = 110.6; 1 df; p < 0.001). This result is probably due to failure of the camera to capture the huge variation and subtleties in the range of normal, and the clinicians' natural inclination to identify pathology, when in doubt. We would conclude that as long as this failing is recognized, clinical photographs, and specifically those from the video-otoscope, represent a useful and reliable teaching tool.

An evaluation of the penetration of cefuroxime axetil into human paranasal sinus tissue.
Nineteen patients presenting for sinus surgery were studied to evaluate the percentage penetration from serum to paranasal sinus tissue of a single orally administered dose of cefuroxime axetil. The methods and results are presented. Cefuroxime penetrates well into human sinus mucosa following oral administration and the concentrations obtained exceed minimum inhibitory concentrations of cefuroxime for the most common pathogens in sinusitis.
Emergency laryngectomy.
From 1974 to 1990, 31 patients underwent emergency laryngectomy for airway obstruction due to laryngeal carcinoma, in an effort to avoid the complication of stomal recurrence. This group of patients had a greater proportion of multiregional tumours (35 per cent vs 13 per cent) than a comparison group of elective laryngectomies. In other respects the two groups were similar. Early post-operative mortality (6.5 per cent vs 3 per cent), stomal recurrence rates (4.2 per cent vs 4.8 per cent) and survival (53 per cent vs 55 per cent) were not significantly different between the emergency laryngectomy group and the comparison group undergoing elective laryngectomy.

Recurrence in juvenile angiofibroma.
A potential for recurrence of juvenile angiofibroma exists after all treatment modalities, both surgical and medical but the methods of defining recurrence and failure to cure varies considerably from series to series. To evaluate factors which might influence successful treatment, a series of 33 patients have been reviewed retrospectively. All patients were treated by simple or extended lateral rhinotomy as a primary or secondary procedure. The final long-term disease control rate was 97% but during the treatment period the overall symptomatic recurrence rate was 50%. However, amongst those treated primarily the recurrence rate was 34%. Of the factors examined, the strongest predictor of recurrence was preoperative embolisation. This group exhibited both early and multiple recurrence when compared with the non-embolised group and the possible reasons for this are examined.
