SIgA- and IgG-coated bacteria obtained from 17 discharging middle ears (14 patients, 9 male, 5 female, age range from 1 to 79 years) were evaluated using an immunofluorescence assay. Simultaneously, quantitative and qualitative bacteriological analyses of the middle ear effusions (MEEs) were performed. MEEs containing Staphylococcus aureus harboured bacteria which were intensely coated with both SIgA and IgG antibodies. In contrast, MEEs containing Pseudomonas aeruginosa displayed minimal, if any, SIgA- and IgG-coated bacteria. Two young patients harboured bacteria (Haemophilus influenzae and S. aureus/Streptococcus pneumoniae, respectively) which were heavily coated with IgG, but not with SIgA. Immunoglobulin-coating of bacteria involved in otitis media is of the utmost importance in eradication of the infection.

Accurate bone-conduction testing with masking is always difficult, but for clinical purposes limited accuracy suffices. However, when assessing claimants for compensation, extreme care is needed since even small apparent air-bone gaps are sometimes translated into financial abatement. This paper sets out the stringent test conditions required to achieve adequate precision. It also indicates the inaccuracies inherent in such tests, and recommends procedures for interpreting the significance of bone-conduction thresholds.

The anatomy of the different layers of the temporalis fascia is reviewed. The superficial and deep layers of the temporalis fascia have been studied by light microscopy to assess any histological difference between the two. We have also assessed the physical characteristics of the different layers by measuring their Young's modulus in the wet and dry states.

Anatomically the superficial layer is part of the epicranial aponeurosis and thus covers nearly the entire lateral aspect of the skull. The deep temporal fascial layer covers exactly the temporalis muscle and measures 10 × 12 cm. The fascial layers have a separate arterial and venous supply enabling them to be used as a homograft, a rotation flap or free microvascular flap. Histologically there is no difference between the two layers. A study of the physical characteristics of the two fascial layers using Young's modulus revealed no significant difference in elasticity between the two. The most significant factor affecting the elasticity was the state of hydration of the fascia.

A study of 73 patients with retraction pockets of the pars tensa (93 affected ears) has been carried out. Of these 32 per cent had otalgia and 31 per cent reported episodes of aural discharge. Adequate audiometric data was available on 75 ears. Mean air-bone gaps were calculated using 500 Hz, 1000 Hz, 2000 Hz and 4000 Hz. Thirty per cent of ears had air-bone gaps of less than 10 dB and in 93 per cent the air-bone gap was less than 30 dB. Air-bone gaps of more than 40 dB were found in seven per cent. Of this group, seven patients were selected for surgical treatment. In all cases the retraction pockets were elevated and everted. In six cases, the thinned tympanic membrane was reinforced with a composite graft of cartilage and perichondrium. This technique has also been used in three patients not included in this study group. An ossiculoplasty was performed in four cases. In the early months, the retraction pockets remained completely everted. However, by 12 months some degree of retraction had recurred in four of the six patients who have been followed for more than 12 months.

The results of ossiculoplasty are frequently reported in terms of closure of the air-bone gap. This parameter is a reliable indicator of the degree of technical success, and is useful in comparing different materials and types of reconstructions. However, assessment of the operated ear alone does not evaluate the effect of surgery on binaural hearing ability, leading to the situation where sub-optimal advice may be given to patients pre-operatively. This article advocates a more patient orientated method of assessing the results of ossiculoplasty. Previous studies have indicated that the operated ear must reach an air conduction level of 30 dB for the speech frequencies, or be within 15 dB of the other ear, to ensure that the patient will gain significant benefit. A graphical method for the prediction of patient benefit is presented, and compared to the rule of thumb quoted above. The implications for surgeons and patients considering ossiculoplasty are obvious.

Many statements routinely made to patients prior to surgery for conductive hearing loss are unduly optimistic and unrelated to the realities of reported results. There is a need to determine what types of such hearing losses can be helped surgically, and more importantly to what extent the patients hearing disability can be relieved.

Despite the fact that around 12 per cent of adult patients attending an audiology department will be severely hearing impaired (pure tone averages of 0.5, 1, 2 and 4 kHz of 70 dB HL or worse in the better hearing ear), their clinical and audiometric characteristics have not been well documented.

These characteristics were collected prospectively in 132 adult patients attending a Severe Impairment Clinic, set up to manage their specific problems. The inability to provide sufficient masking makes audiometric assessment of the severity of the impairment uncertain in the poorer hearing ear in 52 per cent of these patients. In addition, the limited bone conduction output makes it almost invariably impossible to assess the masked bone conduction thresholds and hence the air-bone gap in the poorer ear. Hence, accurate characterization is only practical of the better hearing ear in such patients.

In 67 per cent of the better hearing ears, there was a mixed hearing impairment, the air-bone gap being 20 dB or greater. The aetiology of the conductive component was almost equally otosclerosis and chronic otitis media. In only 19 per cent was the impairment of a pure sensorineural type, broken down as 6 per cent congenitally acquired, 5 per cent due to meningitis and 9 per cent being adult in onset. In the remaining 14 per cent of patients the type of impairment could not be classified as the bone conductive thresholds were off scale.

Having had experience of managing these patients at a special clinic and knowing the workload involved, it is argued that consideration be given to setting up such clinics in most departments.

Sixty-three patients undergoing surgery to the nasal septum followed by bilateral packing had pre- and post-operative tympanometry in order to determine the effect on eustachian tube function. Fifty-five of the 126 ears tested (46 per cent) developed a reduction in middle ear pressure of at least 50 daPa; 76 per cent became normal within 24 hours of removing the nasal packs. All ears were asymptomatic and no patient had evidence of middle ear effusion. Nasal packing following septal surgery is a frequent cause of shortlasting eustachian tube dysfunction but rarely severe enough to cause symptoms or middle ear effusion. Tubal dysfunction is most likely due to a combination of surgical oedema and a direct effect of the nasal packing.

Nasal symptoms are a frequent cause of referral to paediatric ENT clinics. It is the policy of our unit to view sinus radiographs without a report at the initial clinic attendance. This study demonstrates there is no statistically significant difference in the interpretation of the radiographs between two ENT surgeons and a radiologist although there was a tendency for the radiologist to have a greater specificity. This finding may have financial implications. In addition a clear sinus radiograph is shown to be a significant negative finding.

We report our experience of submucous resection of the nasal septum under local anaesthesia as an outpatient procedure. We have audited 50 consecutive cases and compared the results with a similar group of patients in whom the operation was carried out in the usual way under general anaesthesia. We have found the procedure to be safe, effective and economically advantageous.

Angiofibromas of the postnasal space are an enigma to the treating surgeon in view of their extensions around the skull base. The availability of modern investigative procedures has to some extent facilitated the decision making process in choosing a suitable surgical approach.

Proper tumour staging and the earliest and widest possible exposure tailored to the needs of the specific situation together with adequate blood replacement is the key to success in minimizing the chances of the recurrence.

The present study aims at an evaluation of the methodology adopted in 100 serial cases of angiofibromas of the postnasal space. After initial surgery, a further 31 procedures were needed for the management of recurrences.

Pus obtained by needle aspiration of 91 peritonsillar abscesses was examined microbiologically. A positive culture was obtained in 55 patients (60 per cent). Sixty-four bacteriological isolates were grown. Forty patients had a pure growth of a single organism, of which 21 (53 per cent) were beta Haemolytic streptococci. Pure growths of Staphylococcus aureus were found in only three patients. Fifteen patients had mixed organisms, including anaerobes, in their pus and the resistance to penicillin was low. Only the bacteroides species were generally penicillin resistant. The vast majority of patients made a good recovery following needle drainage of the abscess and treatment with parenteral penicillin. The patients with a mixture of penicillin sensitive and penicillin resistant organisms also made a good clinical recovery following needle drainage and administration of parenteral penicillin. The relevance of these findings in the pathogenesis and management of peritonsillar sepsis is discussed.

A histological study was performed of biopsies taken from jejunal free grafts used in pharyngeal reconstruction. The main findings were a decreased crypt/villi ratio and a mild chronic inflammatory infiltrate. There was no evidence of metaplastic or dysplastic transformation.

A prospective study searching for associated mycobacterial infection of the upper aerodigestive tract in patients with cervical tuberculous lymphadenitis (TBLN) was carried out. One hundred and thirteen patients with a clinical suspicion of cervical TBLN were included. All patients had a physical examination of the upper aerodigestive tract. Routine endoscopy and biopsy of the nasopharynx were performed. All of them had surgery to the cervical lymph node. Seventy-five patients had histologically confirmed cervical TBLN. Culture of the lymph node specimen showed Mycobacterium tuberculosis in 68 (90 per cent). In 45 (60 per cent) patients with cervical TBLN the primary foci of infection could not be found. Twenty-nine (39 per cent) had radiographic evidence of active or healed pulmonary tuberculosis. Sputum culture from two patients showed Mycobacterium tuberculosis. Five patients (six per cent) had tuberculous nasopharyngitis. In one of them (one per cent) the tuberculous nasopharyngitis was primary as no other evidence of mycobacterial infection was found. In the present study, mycobacterial infection of other parts of the upper aerodigestive tract was not found.

Twenty-seven patients on chronic haemodialysis and with secondary hyperparathyroidism underwent subtotal parathyroidectomy during the period 1985–1989. The operation was indicated by severe clinical symptoms and evidence of radiological abnormalities not responsive to conservative treatment (low phosphorus diet, phosphate binding substances, oral calcium and vitamin D). If despite intensive medical management, inadequate control of parathyroid hyperplasia continues surgical intervention becomes necessary. Ultrasonography was performed pre-operatively in all 27 cases and detected 42 of 99 glands (42.5 per cent). Also scintigraphy was carried out in every patient but it gave a relatively low detection rate (24.5 per cent). Surgery was followed by improvement in 20 patients and progression of hyperparathyroidism in seven cases. Three of the seven patients failed to improve after subtotal parathyroidectomy, necessitating a reintervention; the remaining four responded sufficiently to medical therapy. From our experience we conclude that subtotal parathyroidectomy for renal hyperparathyroidism is recommended.

A case of malakoplakia, of the temporal bone in a nine-month-old male child is reported.

The lesion presented as an aural polyp, associated with a lower motor neuron facial palsy. On exploration, the granuloma was noted to involve the temporal bone, eroding the bony labyrinth. It was successfully treated with surgical debridement, and antibiotics. A review of the relevant literature is presented.

A case of Pasteurella multocida meningitis, following a mastoidectomy is presented. The association of close contact with pets, many of which harbour Pasteurella multocida as part of their normal buccal flora. This case confirms the potential benefit of taking an ear swab prior to mastoid surgery and in seeking an appropriate ‘pet’ history.

The close union achieved between pure grade titanium and healthy bone makes dislocation a rare event. We report the case of the total avulsion of an apparently well-integrated implant from a healthy mastoid bone.

Rhinocerebral mucormycosis is a rare but often fatal condition characterized by an aggressive necrotizing infection spreading from the nose to the paranasal sinuses, orbit and hence to the central nervous system. A case is reported in which a diabetic male with advanced mucormycosis was successfully treated by a combination of surgery, supportive therapy and liposomal amphotericin B. Liposomal delivery allows the drug to be both less toxic and more effective, and this is the first reported case of its use in rhinocerebral mucormycosis.

A rare case of intracranial extension of a naso-ethmoid schwannoma is presented. Its subsequent removal with few sequelae confirmed the benign nature and good prognosis of the disease.

Pseudomonas pseudomallei, a gram negative organism causing melioidosis, is found in tropical and subtropical regions. It may manifest as a pulmonary lesion, osteomyelitis, soft tissue abscesses, abscesses in various organs or in septicaemic form. Melioidosis of the parapharyngeal space has not been reported so far. A case of melioidosis of the parapharyngeal space which was successfully treated by drainage and prolonged antibiotic therapy is reported here. Melioidosis should be suspected in severe forms of deep neck space infection, especially if the patient comes from an endemic area.
