Background and Objectives Endoscopic modified Lothrop procedure (EMLP) is indicatedafter the failure of standard endoscopic sinus surgery techniques to alleviate frontal sinus dis-ease. Three parameters, such as nasal beak thickness (NBT), accessible dimension of frontalrecess (AD), and distance of frontal sinus (DFS), are important in the preoperative evaluationand selection of patients for EMLP. The purpose of this study is to apply the parameters to de-termine the feasibility of EMLP for the Korean population. Subjects and Method Sinus CT was performed on a total of 233 people, and a study wasconducted using 466 bilateral sides with the following parameters: 1) NBT 2) the distancefrom the posterior margin of nasal beak to the anterior margin of skull base (DNBSB) 3) theright and left AD and 4) the right and left DFS. If the values of NBT, AD, and DFS of thestudy group were less than 10 mm, greater than 5 mm and 7 mm, respectively, they were con-sidered candidates for the EMLP. Results DNBSB, NBT, AD, and DFS were 6.97±1.96 mm, 7.01±1.58 mm, 7.16±2.40 mm,a nd 9.47±2.91 mm, respectively. Parameters except DNBSB showed significant differences inmale and female. The feasibility of EMLP was 75.36% for male and 57.89% for female, with68.24% overall. Conclusion The overall feasibility of EMLP was 68.24% for the study group, where feasi-bility was lower for female than for male.
