RESUMO
OBJECTIVE@#To investigate the role of anatomical abnormalities in non-sinusitis-related rhinogenous headache and to evaluate effects of nasal endoscopic surgery for non-sinusitis-related rhinogenous headache.@*METHOD@#Sixty-eight patients diagnosed as non-sinusitis-related rhinogenous headache were selected in this study. They were treated with nasal endoscopic surgery after failed long-term medical treatment. Data from this group were analyzed retrospectively.@*RESULT@#Multiple anatomical abnormalities were noted by endoscopy and sinus computed tomographic scans in the 66 patients. These included nasal septum deviation in 46 cases (67.6%), middle turbinate gasfication in 20 cases (29.4%), protruding ethmoid bulla or uncinate processor in 10 cases (14.7%) and abnormal middle turbinate in 8 case (11.8%). Fifty-six (82.4%) patients showed significant improvement after surgery.@*CONCLUSION@#Non-sinusitis-related rhinogenous headache can be significantly minimized with individual nasal endoscopic surgery, as long as a precise identification of the etiologic anatomical factor can be made.
