Modified hemi-Lothrop procedure for supraorbital frontal sinus access: a case series.

摘要

The lateral recess or supraorbital region of the frontal sinus (FS; pneumatization of the FS over the orbit) is difficult to access endoscopically. Surgical intervention to this region is often limited to external approaches or advanced endoscopic techniques such as the endoscopic modified Lothrop procedure (EMLP). Recently, we described a modification of the EMLP termed the modified hemi-Lothrop procedure (MHLP), which limits the dissection of the EMLP to the ipsilateral diseased FS, thereby sparing the natural drainage pathway of the contralateral nondiseased FS.2 In this study, we investigate the effectiveness of the MHLP and provide our experience with 15 patients who underwent this technique.
