Objective To investigate the microsurgical treatment of giant osteochondroma in pterygopalatine fossa. Methods The clinical data of 1 patient with giant osteochondroma in pterygopalatine fossa admitted to Department of Neurosurgery, General Hospital of the Eastern War Zone in March 2022 was analyzed retrospectively. The relevant literature were reviewed. The patient was admitted due to right facial numbness with decreased olfactory function. The skull CT and MRI examination showed that there was a giant osteoma in the right pterygopalatine fossa, and there were bone changes in right sphenoid pterygoid process, greater sphenoid wing, temporal bone and mastoid process. According to the examination results, osteochondroma of the right pterygopalatine fossa was considered, and the lesions was resected through the infratemporal fossa approach. Results The lesion was completely removed in the operation, and the patient had no obvious complications after the operation. The skull CT showed that the lesion was completely resected postoperatively, and the pathology indicated osteochondroma. Conclusions Osteochondroma of pterygopalatine fossa is rare. Combination of skull CT and MRI is helpful for diagnosis. Resection of osteochondroma in pterygopalatine fossa via infratemporal fossa approach has the advantages of complete resection, less trauma and rapid recovery. [ABSTRACT FROM AUTHOR]
