Samples of pus aspirated from 53 peritonsillar abscesses were examined in detail for aerobic and anaerobic bacteria, and the microbiological results correlated with clinical data in 44 cases. In 45 samples (85%) cultures were positive: 7 yielded organisms consistent with an aerobic infection, mainly Lancefield group A beta-haemolytic streptococci (5/7), and 38 yielded organisms consistent with an anaerobic infection. The anaerobic infections were usually mixed, but in two cases Fusobacterium necrophorum was isolated in pure culture. Peptostreptococcus micros and Streptococcus milleri were the predominant isolates in this group. Direct Gram stain smear and gas-liquid chromatography were useful indicators of the type of infection present. Samples from ten patients (18.9%) grew one or more beta-lactamase-producing isolates. Of the 25 patients prescribed antibiotics by their general practitioners prior to admission, 18 received one or more beta-lactam antibiotics. Most cases of peritonsillar abscess were due to mixed anaerobic infections, Lancefield group A beta-haemolytic streptococci playing a central role in only a minority of cases. In light of these findings and the possibility of infection with beta-lactamase-producing isolates, it is suggested that the first-line antibiotic therapy in this group of patients should include a chemotherapeutic agent directed against anaerobic bacteria.

KEYPOINTS: Transnasal flexible laryngo-oesophagoscopy (TNFLO) is a safe and well-tolerated procedure that may be performed in a procedure room in the outpatient or day-case/main theatre setting. It requires a local anaesthetic and no sedation. It may be used to histologically diagnose or exclude pathology from the nose to the gastro-oesophageal junction. It provides a "one stop" diagnosis service, reducing diagnostic delays, the need for endoscopy under general anaesthesia, barium swallows and follow-up outpatient appointments. Therapeutic procedures such as vocal cord medialization, endolaryngeal laser surgery, insertion of speech prostheses and foreign body removal may be performed without general anaesthesia.

Ectopic and supernumerary teeth occur in a wide variety of sites. Those that have been reportedinclude the mandibular condyle, coronoid process, orbit, palate, nasal cavity and the maxillaryantrum. Eruption of teeth into these sites is rare, and easily overlooked. We present two casesin which eruption of teeth into the nose and paranasal sinuses was associated with significant morbidity and show how this was relieved by appropriate surgery.

INTRODUCTION We describe our experience of the diagnosis and removal of foreign bodies from the pharynx and oesophagus using transnasal flexible laryngo-oesophagoscopy (TNFLO) under local analgesic. The advantages of this novel instrumentation and technique are discussed.PATIENTS AND METHODS Patients were examined with a Pentax 80K Series Digital Video Endoscope after local analgesia. The instrument was passed transnasally examining the oro-and hypopharynx, and then passed into the oesophagus. The presence, type and site of a foreign body could then be established. If a foreign body was detected, such as fish bone, it was extracted using flexible grabbing forceps passed down the instrument channel and delivered through the nasal or oral cavity. The object was then inspected to ensure removal in its entirety. RESULTS Five cases have been successfully managed using TNFLO. CONCLUSIONS TNFLO represents an improvement in the diagnosis and subsequent treatment of a selected group of foreign bodies as compared with established methodologies.

Little benefit was conferred from overnight admission from the point of view of monitoring for primary haemorrhage. A case can be made for either day-case tonsillectomy (hospital stay over the period in which 93% of primary haemorrhages would occur) or the 'belt-and-braces' approach of a 1-week stay (during which all haemorrhages would occur) but current 24-h admission appears illogical.
