Nasal polyps are common, affecting one to four per cent of the population. Their cause, however, remains unknown and it is possible that it is not the same in all patients. They have a clear association with asthma, aspirin sensitivity and cystic fibrosis. Histologically they demonstrate large quantities of extracellular fluid, mast cell degranulation and an infiltrate of inflammatory cells, usually eosinophils. While this appearance would suggest an allergic pathology there is little conclusive evidence to support this in most patients. There is, however, some preliminary evidence to suggest that a local allergic process could be the cause. While allergic fungal sinusitis is a well defined clinical entity with recognized diagnostic criteria the ubiquitous nature of fungal spores makes the role of fungal infection in patients with nasal polyps difficult to determine and currently this remains unclear. Surgical treatment of nasal polyps has declined in recent years as the benefits of medical treatment have become increasingly recognized. There is good evidence to support the use of corticosteroids both as a primary and post-operative treatment in the majority of patients. Other medical treatments require further evaluation before they could be considered a viable alternative to steroids. Assessment of the literature regarding surgical intervention is difficult and there is little evidence on which to base a surgical treatment philosophy. The authors believe that an endoscopic approach using a microdebrider facilitates accurate removal of polyps with preservation of normal anatomy.

A cohort of 973 patients with symptoms of rhinosinusitis and/or facial pain was followed up for a mean of 2 years 2 months and, within this, was a group of 220 with nasal polyps. Only 39 (18%) had pain or pressure as a symptom. Out of the 220 with nasal polyps, 190 had polyps without any purulent secretions and, of these, only 5 (2.6%) had pain attributable to their paranasal sinus disease. Ten out of the 15 with pain and polyps without pus were found to have pain as a result of neurological or medical cause after endoscopic sinus surgery and a trial of medical nasal treatment and, where necessary, drugs to treat neurological conditions. Thirty patients (13.6%) had nasal polyposis and purulent secretions, and, within this subgroup, 24 (79%) had pain as well. Of the 24 with pain and purulent secretions, 19 (80%) responded to treatment for their paranasal sinus disease, a far higher proportion than with nasal polyps without pus. In conclusion, in patients who have nasal polyps without purulent secretions, be cautious about attributing any symptoms of facial pain or pressure as being due to their paranasal sinuses as it is more probable that it is coincidental and the result of a neurological cause.

A case of Wegener's granulomatosis, which presented as chronic otitis media with facial nerve palsy, is described. Early diagnosis is vital if unnecessary surgical exploration is to be avoided. A false negative cANCA may delay the diagnosis, especially in cases of locoregional disease, and a policy of repeated titres should be adopted, if clinical suspicion is high.
