A variety of surgical approaches have been used in the treatment of @entity5 . These approaches usually involve complicated techniques, particularly when they are employed for @entity5 involving the entire clivus. This paper describes the feasibility, efficacy, and safety of the sublabial transnasal approach combined with a partial resection of the nasal floor in the treatment of midline skull base lesions. We performed this approach in three @entity1 with midline @entity129 , including invasive @entity977 involving the whole clivus, @entity82 , and @entity2347 . The rostrocaudal extent of surgical exposure with this technique was the planum sphenoidale superiorly and the lowermost level of the clivus inferiorly. The lateral extent of the exposure was limited to the distance between the bilateral extradural internal carotid arteries. The average time taken to expose the entire length of the clivus was approximately 30 minutes. There were no serious complications related to the surgical procedure. None of the @entity1 developed @entity854 . Experience with these three @entity1 indicates that the sublabial transnasal approach combined with a partial resection of the nasal floor is a safe, less invasive and effective approach in certain cases of @entity5 .
