BACKGROUND: Intracranial complications of sinusitis are always a subject of actuality. They present diagnostic and therapeutic problems. AIM: To study the clinical characteristics and treatment modalities for intracranial complications of sinusitis while insisting on their severity. METHODS: Retrospective study concerning 7 patients who had intracranial complications secondary to sinusitis. RESULTS: Our study was about 3 men and 4 women. The mean age of patients was 24 years. Neurologic signs were the most common symptoms. The diagnosis was confirmed by CT scan and lumbar puncture. The different complications were empyema in 5 cases and meningitis in 2 cases. Treatment included parenteral antibiotic therapy and surgery. The neurosurgical management has been achieved in 3 cases. Control was obtained in 4 cases, the mean receding was 18 months. CONCLUSION: Intracranial complications of sinusitis must be evoked, especially in cases of febrile headache or facial oedema. CT scan must be realized in slightest doubt. The treatment must be started precociously allowing a cure without after-effects.

AIM: To compare preoperative CT scan finding and per-operative lesions in patients operated for middle ear cholesteatoma, METHODS: A retrospective study including 60 patients with cholesteatoma otitis diagnosed and treated within a period of 5 years, from 2001 to 2005, at ENT department of Military Hospital of Tunis. All patients had computed tomography of the middle and inner ear. High resolution CT scan imaging was performed using millimetric incidences (3 to 5 millimetres). All patients had surgical removal of their cholesteatoma using down wall technic. We evaluated sensitivity, specificity and predictive value of CT-scan comparing otitic damages and CT finding, in order to examine the real contribution of computed tomography in cholesteatoma otitis. RESULTS: CT scan analysis of middle ear bone structures shows satisfaction (with 83% of sensibility). The rate of sensibility decrease (63%) for the tympanic raff. Predictive value of CT scan for the diagnosis of cholesteatoma was low. However, we have noticed an excellent sensibility in the analysis of ossicular damages (90%). Comparative frontal incidence seems to be less sensible for the detection of facial nerve lesions (42%). But when evident on CT scan findings, lesions of facial nerve were usually observed preoperatively (spécificity 78%). Predictive value of computed tomography for the diagnosis of perilymphatic fistulae (FL) was low. In fact, CT scan imaging have showed FL only for four patients among eight. Best results can be obtained if using inframillimetric incidences with performed high resolution computed tomography. CONCLUSION: Preoperative computed tomography is necessary for the diagnosis and the evaluation of chronic middle ear cholesteatoma in order to show extending lesion and to detect complications. This CT analysis and surgical correlation have showed that sensibility, specificity and predictive value of CT-scan depend on the anatomic structure implicated in cholesteatoma damages.
