Surgical decompression in traumatic optic neuropathy.

BACKGROUND: The management of traumatic optic neuropathy remains controversial. This retrospective study presents the results of 19 cases of indirect optic neuropathy where surgical decompression represented the primary mode of treatment. METHODS: Nineteen patients (20 optic nerves) with traumatic optic neuropathy underwent primary surgical decompression. The surgery was performed using the transethmoidal technique. RESULTS: The extent of bony optic canal injury documented during surgery indicated that this had been underestimated in this series by CT findings. Vision improved in eight patients, five of whom had had no light perception preoperatively. CONCLUSION: Primary surgical decompression of the optic nerve within 48 h of injury produces beneficial results. Testing of visual acuity 6 weeks after surgery does not serve as a reliable predictor of final outcome.

Are pre-operative vocal fold checks necessary?

Over a 26-year period, from 1970 to 1995, 2250 pre-operative vocal fold checks were carried out by the ENT team at Manchester Royal Infirmary in patients undergoing thyroid, parathyroid and cardiothoracic surgery. A register was kept of all pre-operative fold checks. This register was retrospectively analysed and 23 vocal fold palsies were documented. In six of these patients the notes were either missing or incomplete. All of the remaining 17 patients had a history suggestive of vocal fold palsy. We suggest that in the absence of symptoms, either current or on history, a routine pre-operative vocal fold check is unnecessary.

Non-cardiogenic pulmonary oedema due to foreign body aspiration.

A patient who developed non-cardiogenic pulmonary oedema secondary to acute airway obstruction caused by an aspirated foreign body is presented. The literature is reviewed, discussing the theories regarding the formation of non-cardiogenic pulmonary oedema. The case highlights the importance of this rare complication of foreign body aspiration and surgeons and anaesthetists should be alert to continued respiratory symptoms following relief of acute airway obstruction.

An unusual complication of T-tubes.

The morbidity of long-term ventilation tubes (Goode T-tubes) is often discussed with reference to otorrhoea, tympanosclerosis and long-term perforation. We report three cases of the T-tube slipping into the middle-ear cleft. In two of the three patients this was asymptomatic and the T-tubes were left in situ. In the third patient this complication was documented on three occasions when the T-tube was removed and reinserted for recurrent effusions. We are unaware of this complication being previously reported in the literature.

Multiple cutaneous metastases from laryngeal carcinoma.

A case of laryngeal squamous cell carcinoma recurrence presenting as multiple cutaneous metastases is presented. Such metastases are rare and are associated with a poor prognosis. Treatment is usually aimed at providing pain relief in these patients with a limited life expectancy.

Systemic absorption of gentamicin ear drops.

Aminoglycoside-containing topical preparations are commonly used in the treatment of chronic suppurative otitis media and otitis externa. We report a case where systemic absorption of topical Gentisone HC occurred producing a serum gentamicin level of 6.2 micrograms/ml.

Survival times of Provox valves.

This study was performed to assess the survival times of the Provox valve in the Manchester area. Thirty-nine patients from four hospitals, representing 81 valve failures, were studied. The effects of the timing of the tracheo-oesophageal puncture, previous radiotherapy, and the presence and timing of cricopharyngeal myotomy on valve life were analysed. Regression analysis using an extension of the Cox model to allow strata showed that the lifetime of the first valve only is adversely affected by previous radiotherapy. The other covariates do not have a statistically significant effect on valve survival. The median valve survival is 4.5 months, (range one to 12 months). A small percentage of valve users with particularly frequent valve failures may require additional support and prolonged anti-fungal therapy.

A puzzling paediatric parotid haematoma.

An unusual case of an intra-parotid haematoma is presented. The history was misleading and the ultrasound and CT results apparently contradictory. The investigations are explained in the light of the natural process of haematoma evolution. It is recommended that all radiological investigations be correlated by a single radiologist, and suggested that repeated ultrasound scans, at appropriate time intervals, might be used to confirm the diagnosis and follow the process of clot resolution.

An unusual cause of facial pain.

A case of chronic facial pain and headache is presented. This was found to be due to two pieces of windscreen-glass lodged in the superior meatus of the patient's nose since a road-traffic-accident 14 years earlier. Despite being reported as normal, review of previous X-rays of her sinuses showed that the glass was visible. The importance of carefully assessing the intranasal area on sinus-views is illustrated.

An algorithmic approach to aspergillus sinusitis.

The effective management of paranasal sinus aspergillosis requires early diagnosis, histological classification, surgery and where appropriate, chemotherapy. Fungal sinusitis may be easily missed unless a high index of suspicion is maintained and specific culture and histology requested. The disease is classified into invasive and noninvasive types, each being divided into two subgroups: invasive aspergillosis may be either fulminant or indolent and noninvasive disease localized or allergic. The literature is reviewed and an algorithmic approach to aspergillus sinusitis proposed. The importance of histologically differentiating invasive from noninvasive aspergillosis prior to selecting the appropriate treatment options is stressed. CT scan should precede definitive surgery, and be used in follow-up. Close and prolonged follow-up is essential.

Nasopharyngeal Corynebacterium ulcerans: a different diphtheria.

A case of toxigenic Corynebacterium ulcerans infection is presented. The diagnosis was delayed and no anti-toxin administered. A nasopharyngeal biopsy was complicated by severe haemorrhage necessitating a post nasal pack. A brief review of the pathology and treatment of Corynebacterium ulcerans is given.
