OBJECTIVE: To investigate operative approaches and techniques of reconstruction for rhinosinusal @entity5 involving in the anterior skull base. METHOD: In a retrospective study, clinical data of 22 @entity1 treated surgically in our department from 1988 to 2002 were analysed. Lateral rhinotomy was carried out in 8 @entity1 and ampliative rhinotomy in 4 @entity1 ; in 10 @entity1 craniofacial operation was performed. @entity655 were used to repair lager defect in the anterior skull base. RESULT: All @entity5 were totally resected. In lateral rhinotomy, local locoeled @entity693 happened in 1 case, and 4 @entity1 in craniofacial operation. None complication with cerebrospinal fluid leaks, @entity55770 and intracranial air. All @entity1 were followed up from 6 months to 11 years after surgery. 7 @entity1 died from @entity281 or metastasis of @entity5 . 3-year survival rates was 15/19(78.9%); 5-year survival rates was 13/19(68.4%). The @entity5 invaded the orbital fascia in 9 @entity1 . Vs 4/9 (44.4%) and 2/9(22.2%) for these 3 and 5-year survival rates. CONCLUSION: Selection of operative approaches depends on the size of defects in the anterior skull base, extent of intracranial invasion and location of rhinosinusal @entity5 ; multiple layer fascia flaps can be used to reconstruct bigger defects of the skull base. It is safe, technically easy, effective procedure and worthy to be recommended.
