Objective: To introduction the clinical application and surgical technique of the modified rhinotomy for treatment of skull base neoplasms.
Method: The diagnosis and surgical outcome of 20 patients with skull base neoplasms were reviewed retrospectively.
Result: All the cases were involvement with nasal cavity, ethmoidal sinus, sphenoidal sinus and medial wall of orbit. Two cases were involvement with pterygopalatine fossa, infratemporal fossa and intra calvarium separately. All cases were treated by modified rhinotomy. Among that 2 patient were with juvenal angiofibroma treated by combined with maxillary transposition and pterional and zygomatic approach, and 2 cases were with craniofacial approach. No complications were found relating to surgery. 6 patients was recurrent during follow-up among 6 to 60 months.
Conclusion: The modified rhinotomy is a effective and safe surgical approach to treat skull base neoplasms located in nasal cavity, ethmoidal sinus and sphenoidal sinus. Tumor involved with pterygopalatine fossa, inferotemporal fossa and intracranial extension, other surgical approach should be used at the same time.
