[Caseous sinusitis. Clinical, x-ray computed, surgical, histopathological, biological, biochemical and myco-bacteriological aspects. Apropos of 33 cases].

We analyse the most important clinical, CT, surgical, histopathological, biological, biochemical, mycological and bacteriological features of caseous sinusitis, i.e. chronic, poorly symptomatic sinusitis which are resistant to usual treatment.

Intracanalicular and intratemporal facial nerve schwannomas.

Facial nerve schwannomas can mimic acoustic neuromas. We report herein two cases: a purely intracanalicular and an intratemporal facial nerve tumor extending into the internal auditory canal and the cerebellopontine angle. These tumors have to be suspected in patient with small-size tumors presenting with facial paralysis.

[Tonometric monitoring of the viability of free transplants of the jejunum and the stomach after total circulary pharyngolaryngectomy].

A prospective study concerning the tonometric viability supervision of 9 digestive free autografts after total pharyngolaryngectomy was conducted. This technic is based on the Henderson and Hasselbalch's equation which calculates the intramucosal pH (pHi) in the graft using a tonometric catheter. When the pHi is under 7.

[Cavernous hemangioma of the geniculate ganglion. Value of otoneurosurgical collaboration].

A patient with a progressive peripheral facial paralyses should be considered to have a tumor involved the facial nerve until proved otherwise. Haemangiomas of the temporal bone are uncommon and the present study discusses pathology, clinical presentation and therapeutic management of a tumor located at the geniculate ganglion. Complete surgical removal by the middle fossa approach is the treatment of choice with adequate margins and preservation of adjacent structures when it is oncologically possible.

[Hemangiopericytoma of the infratemporal fossa of nasopharyngeal manifestation. Value of the cervico-transoral approach].

Authors present one case of hemangiopericytoma of the infra-temporal fossa and the lateral wall of the nasopharynx. They describe the characteristics of this rare, recurrent and sometime malignant vascular tumor. The selected therapy is an aggressive and wide exeresis.
