Peritonsillar abscess after tonsillectomy: a review of the literature.

INTRODUCTION: Peritonsillar abscess (PTA) is a common condition with a complicated aetiology. PTA after tonsillectomy is rare. This literature review of PTA in the absence of tonsil tissue aims to collate experience of these cases and examine the wider implications for understanding the aetiology of PTA formation. METHODS: A structured literature review was performed using Ovid MEDLINE®. Keywords 'quinsy' or 'peritonsillar abscess' were combined with 'tonsillectomy'. RESULTS: The search resulted in 212 citations and the identification of 11 cases of PTA formation in the absence of tonsil tissue. The most common indication for tonsillectomy was recurrent tonsillitis or PTA. Nine patients had no interval peritonsillar infection (ie a peritonsillar infection after a tonsillectomy) prior to presenting with the PTA. The mean interval between tonsillectomy and PTA was 16 years. All patients were managed either by incision and drainage or by needle aspiration with or without antibiotics. CONCLUSIONS: PTA in the absence of tonsil tissue is rare. Potential sources of infection include congenital branchial fistulas, Weber's glands and dental disease. These alternatives should also be considered in patients presenting with PTA formation in the absence of concurrent tonsillitis and may influence management decisions.

Audit of headache following resection of acoustic neuroma using three different techniques of suboccipital approach.

A retrospective case notes review using pain visual analogue scale (VAS) and assessment of analgesia required by patients in the post-operative period at 1, 3, 6, 12 and over 12 months following acoustic neuroma resection was performed. Glasgow Benefit Inventory (GBI) score was used to assess the change of quality of life and its relationship to pain following surgery. Questionnaires of 71 patients were included in the study, 23 of whom underwent wide craniotomy including dissection of upper cervical musculature (CE), 25 wide craniotomy with replacement of bone flap (CO) and 23 minimally invasive, approximately 2 x 2 cm, minicraniectomy (MCE). The minicraniectomy resulted in significantly diminished pain from third month post surgery as compared with wide craniectomy (p < 0.05) and patients required less analgesia. Similarly, CO patients have experienced significantly less pain than CE patients (p < 0.05), but only after 12 months following surgery. Although consistently less in absolute visual analogue scores, there was no statistically significant difference between the amount of pain recorded by CO and MCE patients. There was no correlation between gender or age and the VAS pain score. The mean Glasgow Benefit Inventory score for all patients was -6.6, and there was no significant difference between operation types, genders or age. Although bone flap replacement appears to diminish the amount of post-operative pain, minimal invasive technique resulted in least pain following acoustic neuroma resection in our patients.
