Abstract
The objective of this study is to present our experience in endoscopic surgery of lesions in the anterior skull base, to describe the transcribrifom endoscopic technique and show its indications and contraindications. We present a series of 73 patients operated at Ali AitIdir Hospital by extended endoscopic approach (trans cribriform endoscopic approach) including: 16 fronto-ethmoidal meningo-encephalocoele, 04 esthesioneuroblastoma, 04 ethmoidal adenocarcinomas with intracranial extension, 45 dural defects at the cribriform plate of ethmoidal bone and 04 olfactory meningiomas. 32 females and 41 males with a mean age of 35,5 years. Anosmia was the major symptom in olfactory meningiomas. For the cerebrospinal fluid leakage due to dural defects, the most frequent clinical symptom was rhinorrea, associated with meningitis in 37 patients. The most frequent dural defect site was the cribriform plate of the ethmoid bone in 42 patients.Other clinical signs were nasal obstruction, exophtalmia, respiratory distress and epistaxis. All the patients were operated by a trans cribriform trans ethmoidal endonasal endoscopic approach, with good post operative outcomes.Eight patients were sent to radiotherapy. Long term follow up revealed recurrence of rhinorrhea in 04 patients operated for a dural defect.
