Ninety-five peribulbar blocks for cataract extraction with intraocular lens implantation were performed by an anaesthetist over a period of 6 months. The quality of the block was assessed by the ophthalmologist and the anaesthetist. No dangerous local or systemic complications were observed. Peribulbar anaesthesia is increasingly preferred to retrobulbar block on account of its easiness and safety.
Mondini's malformation is a rare internal ear malformation. It's often discovered in childhood in the course of perception deafness check up, or repetitive meningitis in some other cases. The authors report a case of complex Mondini's malformation with fistulas of cerebro-spinal-fluid in oval and round windows, and stress the interest of high resolution computed tomography.
Malignant external otitis is a progressive necrotizing otitis. It's a rare severe and evolutive clinical entities, old diabetics are the most victim. Pseudomonas aeruginosa is the bacteria responsible in the most cases. Prognostic vital can be affected, treatment must be energic, rapid and well adapted.

The authors report a case of a jugular bulb dehiscence extending to the tympanic cavity. They alert that the finding of a blue mass in the middle ear should evok the possibility of a vascular variant or abnormalitie. High resolution CT is extremely helpful in the correct diagnosis by showing the subtle and characteristic bone changes.
Histiocytosis X is an uncommon disease. Temporal bone involvement is a frequent head and neck manifestation. Most patients are under fifteen years of age. The authors report a case of a bilateral extensive temporal involvement complicated with vertigo and peripheric facial palsy. CT plays a dominant role in the diagnosis because of the ability to identify bone destruction, soft tissue involvement and intra-cranial histiocytosis more accurately.
