Cells pneumatizing through the frontal ostium may vary in the degree of frontal sinus penetration. This series describes the use of the axillary flap technique and the endoscopic modified Lothrop procedure (EMLP) for the removal of cells that pneumatize to a varying degree through the frontal ostium into the frontal sinus.
Out of a total of 204 patients undergoing endoscopic sinus surgery, 31 patients had a cell on one side and 7 patients had bilateral obstructive cells resulting in 38 sides undergoing an axillary flap approach for the removal of the obstructing cell. In 13 patients, the obstructing cell was deemed inaccessible by conventional technique and these patients underwent an EMLP for removal of the obstructing cell.
All patients who underwent both the axillary flap approach and the EMLP had a patent frontal ostium confirmed endoscopically at the last follow-up visit. However, 8 of the 38 sides (21%) that underwent the axillary flap procedure had residual minor symptoms with four patients (30%) who underwent an EMLP having a recurrence of minor symptoms
The axillary flap and the EMLP can be used to remove successfully ethmoidal cells that have pneumatized through the frontal ostium.
经额窦口气化的气房在额窦内的穿透程度可能有所不同。本系列研究描述了使用腋瓣技术和内镜改良 Lothrop 手术（EMLP）来切除经额窦口不同程度气化至额窦内的气房。
在总共 204 例行内镜鼻窦手术的患者中，31 例患者一侧有一个气房，7 例患者双侧有阻塞性气房，共 38 侧采用腋瓣入路切除阻塞性气房。13 例患者中，阻塞性气房被认为用传统技术无法触及，这些患者接受了 EMLP 以切除阻塞性气房。
所有接受腋瓣入路和 EMLP 的患者在最后一次随访时经内镜证实额窦口通畅。然而，在接受腋瓣手术的 38 侧中，有 8 侧（21%）有残留轻微症状，接受 EMLP 的 4 例患者（30%）有轻微症状复发。
腋瓣和 EMLP 可成功用于切除经额窦口气化的筛骨气房。
