Skull base osteomyelitis interpreted as malignancy.

Lesions in the skull base may present difficulties in diagnosis primarily because the access needs to be invasive and one has to rely on imaging that may still be misleading. The case presented here illustrates this example in that the patient had abnormalities on computed tomography (CT) and magnetic resonance image (MRI) scans quite convincing of malignancy but which with time proved, essentially through clinical judgment, to be skull base osteomyelitis secondary to malignant external otitis (OME).

An analysis of the aetiology of early childhood deafness.

It is generally believed that one in every thousand children is profoundly deaf. An understanding of the aetiology of early childhood deafness and timely detection is crucial in rehabilitation of these children. This study analyses the aetiology of early childhood deafness and shows that deafness is more often acquired than inherited. Non-syndromic deafness, especially occurring on its own, usually produces profoundly deaf children and thus there is the need for genetic studies--in the child, laterally, and longitudinally into generations. Meningitis appears to be the commonest cause of acquired deafness, especially if due to pneumococcus. Only 40 of the 80 cases presented before the age of 2 years. It was therefore interesting to note what factors invoked awareness of deafness to facilitate early presentation.

Subtotal laryngectomy with myomucosal shunt.

This is a modified subtotal laryngectomy. On the tumour-free side of the larynx, some posterior structures, with their neurovascular supply are preserved. The endolaryngeal mucosa is tubed in continuity with the trachea below and projects into the pharynx above. Thus a myomucosal shunt is formed. Air is directed into it by finger occlusion of the tracheal stoma. The voice production is highly satisfactory. Aspiration is prevented by constriction of the thyroarytenoid muscle which provides a valved upper end of the tube. The possibility of leaving tumour in the laryngeal remnant is eliminated by careful selection of patients, and re-confirmation of tumour extent intra-operatively and a frozen section. Eleven such operations have been performed since October 1983 for squamous cell carcinoma, some previously irradiated. None of the patients had local recurrence. Only one had an aspiration problem which later resolved. All acquired a satisfactory voice.

A rare intracranial complication of cholesterol granuloma.

A large extradural collection of fluid was encountered in a patient with mastoid cholesterol granuloma. She gave no previous history of ear disease and had no aural symptoms. She presented merely with headache. Some authors have suggested non-surgical intervention (Farrior and Kampsen, 1981) or perhaps just an insertion of a ventilating tube (Burton and Wright, 1960). Our experience would suggest that active intervention and radical surgery are indicated to halt serious complications of cholesterol granuloma.
