[Endocranial complications of cholesteatoma: apropos of 8 cases].

The authors present a recent series of 8 cases of intracranial complications secondary to cholesteatoma. The series is made up of 3 temporal lobe abscesses, 1 parietal lobe abscess, 1 cerebellar abscess, 1 extradural abscess, one lateral sinus thrombo-phlebitis with subdural abscess and one meningitis on its own. Otological management with removal of the cholesteatoma was by open or closed technique, depending on the local anatomical conditions. It was supplemented by multiple antibiotic therapy, in turn guided by the bacteriological cultures and by any known epidemiological information. It was necessary to needle the abscess by a neurosurgical approach in two cases. The results of bacteriological samples taken for analysis from the intracranial abscesses are often negative, which limits their clinical value. In such cases, the choice of antibiotics rests on epidemiological information. The authors emphasise the progress that has been made towards the early diagnosis of intracranial complications. Appropriate combined medical and surgical treatment leads to complete cure without neurological sequelae in most cases.

[Acute vertigo caused by ischemia of the postero-inferior cerebellar artery or PICA. Apropos of 2 cases].

Based on two cases and a review of the recent literature, we would like to draw attention to the fact that a cerebellar infarction, localised to the territory of the PICA, can present with just a single clinical feature-acute rotary vertigo. Cerebellar vascular accidents remain a little known cause of acute vertigo, often masquerading as a peripheral vestibular disturbance. The main differential diagnosis is vestibular neuronitis. The prognosis is usually good, but the risk of a late recurrence or of a further cerebro-vascular episode is difficult to predict. This uncommon aetiology should not be ignored because of the risk of progression towards a sort of pseudo-tumoral infarct, in which the risk of a fatal outcome remains ever present. In most cases, however, sequelae are few or absent.

[Temporo-sphenoidal giant cell tumors, apropos of a case].

The authors report an extremely rare case: a bony giant cell tumour in the temporo-sphenoidal region presenting with hearing loss and vertigo. The main characteristics of these tumours are given, together with a literature review. This is the 5th published case of this tumour in the temporo-sphenoidal region. The treatment of these tumours is essentially surgical, and the authors emphasise the use of Sekhar's approach.

[Hypoglosso-facial anastomosis: results and technical development towards end-to-side anastomosis with rerouting of the intra-temporal facial nerve (modified May technique)].

The authors report their experience with 31 hypoglosso-facial anastomoses mainly carried out after removal of tumours of the cerebello-pontine angle, 26 were available for evaluation: at 18 months there were 5 of grade II, 19 of grade IV and 2 of grade V. Only one patient was dissatisfied with the result. 24 of the patients had received their hypoglosso-facial anastomosis using the clinical technique of Korte. In 3 cases the operation was by the technique of May. The authors suggest a variation of May's technique: it was carried out on the last 4 patients. It consists of a hemi-hypoglosso-facial anastomosis with rerouting of the mastoid portion of the facial nerve, without using a nerve graft. The aim of this technique is to reduce the sequelae of hemi-lingual atrophy and paralysis (which gives trouble with articulation, mastication and deglutition). The authors' experience confirms that these sequelae are greatly reduced, if not abolished. The functional results in terms of facial movements were satisfactory and consistant: 43.7% were quantified--with 3 of grade II and one of grade IV on the House Brackmann scale.
