RESUMO
Objective To analyze and discuss the surgical outcome and complications of resection of pterygopalatine fossa tumor along the lateral wall of maxillary sinus.Methods Nine patients with pterygopalatine fossa tumors received from March 2012 to June 2015 were treated by transnasal endoscopic approach to resect the pterygopalatine fossa tumors by transnasal recess-maxillary sinus approach.Surgery used general anesthesia,while controlling intraoperative hypotension in patients.The CT and MRI examinations of the sinuses were performed before operation,and the patients were followed up regularly.Results All of the patients underwent successful operation.The pterygopalatine fossa tumors were cleared once,and were discharged after 6-12 days.Although there were 2 patients with mild facial paralysis of the maxillary nerve in 3-24 months of follow-up,there was no serious complication or recurrence.Conclusion The removal of pterygopalatine fossa tumors by transnasal endoscopic approach can safely and effectively remove the tumor tissue and preserve the integrity of the lateral wall of the nasal cavity,minimize facial trauma and nasal cavity function.It is a complication less,low recurrence rate,rapid recovery of the new minimally invasive approach,it is worth to promote the use of clinical.
