[Frontal mucocele. Clinical symptoms, treatment and results apropos of 17 cases].

The ophthalmological signs are stressed in the management of frontal mucoceles. The authors report good results of their surgical technique with bicoronal approach, exenteration of the pathology and complete obliteration of the frontal sinus by bone chips.

[Endocranial complications of chronic otitis in adults].

47 patients with intracranial abscess were admitted in the neurosurgical department of Professor Fohanno Pitié-Salpêtrière Hospital, between 1973 and 1989. Most often central abscesses were found. In 9 cases, the ear was the primary septic focus: 3 chronic otitis with cholesteatoma, 6 chronic otitis without cholesteatoma.

[Sinusitis during intensive care. Prospective studies].

Two series of ICU patients, the first one with nasal endotracheal intubation, the other one with a tracheostomy, were included in a prospective and comparative study with repeated CT scans of the sinuses. Radiological sinus involvement is seen in both groups almost constantly; purulent sinusitis are often seen in both series. Unexplained fever should make us look for a sinusitis, even in patients with early tracheostomy.

[Frontal and ethmoidal mucoceles. Apropos of 17 cases].

We have been studying 17 cases for operated mucoceles over a period of 4 years. Usual predisposing factors are often present, however we found no underlying malignant tumor revealed by a mucocele. Surgical treatment always included exclusion and filling with bone grafts in case of frontal involvement.

[Post-traumatic decompression of the optic nerve. Ophthalmologic and x-ray computed tomographic evaluation. Results in a series of 23 cases].

Post traumatic optic nerve compression gives a Clinic picture of physiological section. CT Scan is consistent with optic canal lesion when considering direct signs (bony fragments compressing the nerve) or indirect (fractures and hematoma of posterior orbital wall, of posterior ethmoid, and sphenoid). 23 patients had a surgical decompression through transethmoidosphenoidal approach.

[Amyloidosis disclosed by ORL manifestations].

Amylosis is characterized by an infiltration of acellular substance into the tissues. This substance is mainly made of protein molecules. This disease is primary or secondary to general disorders.
