[Scanner-guided puncture biopsy of a lesion occupying the pterygo-maxillary fossa].

A 26-year old male patient was referred to us for impaired mouth opening. Actually, Mr. B. has been followed up for SADAM for 2 years at different hospital services. In view of the ineffectiveness of the treatments administered (occlusal releasing gutter, antiinflammatory agents) and due to occurrence of severe episodes of earache refractory to conventional analgesics, we request that a CT-scan be obtained to evidence the process invading the pterygopalatine fossa. ENT examination and scanner-guided needle biopsy are performed to enable anatomopathological analysis and diagnosis.
