Anatomical considerations of the frontal process of the maxilla for the endoscopic lacrimal surgeon
The FPM's thickness and geometry hinder full bone removal during unpowered endoscopic DCR, particularly in the superior region. In 12% of cases, over one-third of the FPM may be inaccessible with standard rongeurs, risking incomplete sac exposure. These anatomical findings highlight the need for preoperative imaging and may guide the selection of surgical instruments to improve operative outcomes.
