Comparison between two valsalva techniques for improvement of hypopharyngeal nasendoscopy: a preliminary communication.

OBJECTIVE: To compare the nasal valsalva with the trumpet manoeuvre and anterior neck skin traction as aids to nasendoscopic examination of the hypopharynx. DESIGN: Randomised, controlled comparison of examination techniques. SETTING: Single tertiary referral centre. PARTICIPANTS: Twenty-six adult patients requiring hypopharyngeal nasendoscopic examination were recruited. Patients were examined with both techniques in a randomised order that was recorded to video cassette. MAIN OUTCOME MEASURES: Blinded assessment of the percentage visualisation of the pyriform fossae, post-cricoid and upper oesophageal sphincter was carried out by three consultant otolaryngologists independently. RESULTS: Mean percentage scores (and 95% confidence intervals) for nasal valsalva versus trumpet manoeuvre for the three consultants, respectively, were as follows: right pyriform fossa: 77(68, 87) versus 80(71, 91), 61(55, 66) versus 60(54, 66), 46(38, 54) versus 45(37, 54); left pyriform fossa: 76(65, 87) versus 80(69, 91), 59(53, 64) versus 55(49, 61), 42(35, 49) versus 42(35, 50); post-cricoid: 55(44, 67) versus 59(47, 71), 53(46, 60) versus 53(46, 60), 32(25, 39) versus 32(25, 39); upper oesophageal sphincter: 11(1, 21) versus 21(11, 31), 15(9, 21) versus 20(14, 26), 4(0, 8) versus 7(3, 11). No significant difference was found between the two techniques at any subsite. Individual differences were noted in a minority of patients where one or other technique gave a clearly improved view. CONCLUSIONS: The nasal valsalva and the trumpet manoeuvre with anterior neck skin traction are complementary techniques for improving the view of the hypopharynx.

Three cases of mycobacterial cervical lymphadenitis.

Three cases of mycobacterial cervical lymphadenitis in children are presented. The diagnosis and treatment are described in brief. None of the patients were from the risk groups traditionally associated with tuberculosis. With an increasing number of tuberculosis cases reported in the UK, the need for awareness of this re-emerging condition to ENT surgeons and paediatricians is stressed.

Radiotherapy in the treatment of middle ear and mastoid carcinoma.

The treatment of temporal bone carcinoma is a widely discussed topic with marked variation in published results. Most conclude that a combination of radical surgery and radiotherapy is the optimum treatment. The present study reviews the results of radiotherapy used as the main primary treatment for this condition. Five-year survival in 56 patients was 32% for radical and palliative therapy, with an excellent response in 'early' cases. It is concluded that improvement in survival could be attained by defining those groups which would benefit from a combination of treatment methods.

Acoustic neuroma (schwannoma) surgery 1978-1990.

A series of 151 patients with 154 acoustic schwannomas have been operated upon in Manchester Royal Infirmary by a joint Otological and Neurosurgical team, employing either the translabyrinthine or the suboccipital approach. The perioperative mortality rate was 3 per cent. Anatomical preservation of the facial nerve was achieved in 89 per cent of tumour removals and a good to normal functional result in 79 per cent of cases. Attempts at hearing preservation have been unsuccessful, largely because of the small number of patients in the series in whom useful hearing was present preoperatively. Complications included major brain stem ischaemia (1.2 per cent), CSF fistula (5 per cent) and facial dysaesthesia (7 per cent). The incidence of mortality and morbidity is directly related to tumour size and to the experience of the surgeons. A number of patients experienced an unusual type of post-operative dreamlike state which appeared to be a form of hypnagogic hallucination, and the possible neurophysiological mechanism responsible for this phenomenon is discussed. The continuing failure to attain the ideal of early diagnosis is lamented, and the importance of a flexible bidisciplinary surgical approach emphasized.

Otogenic Fusobacterium necrophorum meningitis.

A case of meningitis secondary to acute suppurative otitis media in a previously healthy child is reported. The only organism isolated from blood after aerobic and prolonged anaerobic culture was identified as Fusobacterium necrophorum. Complete recovery followed treatment with surgery and prolonged antibiotic therapy. The role of anaerobes in the development of meningitis, the isolation and identification of Fusobacterium necrophorum, the clinical presentations of F. necrophorum infection and the choice of antibiotics in the treatment of these infections are discussed.

Recovery from sensorineural deafness in Wegener's granulomatosis.

Wegener's granulomatosis may present with deafness or other aural symptoms. This report describes two patients with histological evidence of Wegener's granulomatosis who developed reversible sensorineural hearing loss during the course of their illness. The first patient showed complete recovery of a sensorineural hearing loss averaging 50 dB after ten months treatment with cyclophosphamide and high-dose prednisolone. The second patient, who was on maintenance haemodialysis, achieved a 40 dB improvement in sensorineural hearing loss within two weeks of adding cyclophosphamide to pre-existing corticosteroid therapy. These findings suggest that the prognosis of sensorineural hearing loss in Wegener's granulomatosis can be improved with suppression of the vasculitic process by early treatment with combined cytotoxic-immunosuppressive therapy.

Experience with a new topical anaesthetic in otology.

Producing good local anaesthesia of the external auditory meatus and tympanic membrane has always been a difficult problem facing otologists. Previously used methods are mentioned and the use of a new eutectic mixture of local anaesthetics (EMLA) for electrocochleography, myringotomy and grommet insertion in adults and older children is described. A double-blind controlled trial involving 15 patients (30 ears) undergoing electrocochleography showed EMLA to be a very effective, safe and convenient preparation for outpatient otological use.
