Abstract:

Objective To compare endonasal transsphenoidal via anterior wall of sphenoid sinus approach with endonasal transsphenoidal via nasal septum-sphenoid sinus approach by imitation of the endoscopic surgery. Methods  The head of 15 samples were dissected respectively via two above mentioned approaches as an imitation of the endoscopic surgery, and the distance between incision and external nostrils, maximum angle and range of swing were measured in the horizontal direction on operative route and other related anatomic parameters. Results Distances between incision and external nostrils of anterior wall of sphenoid sinus approach and nasal septum-sphenoid sinus approach are (5.19±0.15) cm versus (0.59±0.52) cm; maximum angle and range of swing in horizontal direction on operative route are (44.77±2.04)°versus (38.54±1.40)°, and (1.25±0.15) cm versus (0.68±0.05) cm. The correlation data of the two approaches were statistically significant(P<0.001). Conclusions Endonasal transsphenoidal via nasal septum-sphenoid sinus approach incurs milder damage, enjoys short distance to the outside of the nose, clear positioning, wider operation space and larger perspective surgical approach, which is worthy of clinical promotion.
