Cosmetic rhinoplasty and maxillary sinus surgery are rare causes of lacrimal obstruction. The lacrimal sac is quite vulnerable to damage by the lateral osteotomy of the rhinoplasty. While obstruction from such damage usually resolves in three months, these three cases illustrate the risk of perisitent obstruction, particularly in complicated cases. The nasoantral window in the Caldwell-Luc may damage the distal lacrimal opening if it is placed too high, or made too large. Occasionally, the duct will extend more anterior and inferior and be quite vulnerable to damage by the nasal antrostomy.
隆鼻术和上颌窦手术是泪道阻塞的罕见原因。泪囊很容易在隆鼻术的外侧截骨术中受到损伤。虽然这种损伤导致的阻塞通常在三个月内缓解，但这三例病例说明了持续阻塞的风险，尤其是在复杂病例中。柯-陆氏手术中的鼻上颌窦开窗术如果位置过高或开口过大，可能会损伤泪道远端开口。偶尔，泪道会更向前下方延伸，很容易在鼻窦造口术中受到损伤。
