Anterior laryngeal webs can be congenital or acquired and occur secondary to a surgical procedure, intubation, or infection. Clinical presentation can include vocal and respiratory symptoms. The first step in managing a laryngeal web is performing flexible laryngoscopy, followed by a direct laryngoscopy under general anesthesia. Treatment remains a challenge. Endoscopically, the web can be incised with cold instruments or by laser, mitomycin-C can be applied, and a silastic keel can be inserted in the anterior commissure. Externally, an anterior cricothyrotomy is necessary and a silastic keel can be placed; anterior cartilage graft can be inserted in case of a thick web. Regardless of the technique used, the primary concern is recurrence.
先天性或后天性均可发生前位喉蹼,继发于外科手术、插管或感染。临床表现可包括发声和呼吸症状。处理喉蹼的第一步是进行可弯曲喉镜检查,随后在全身麻醉下进行直接喉镜检查。治疗仍然是一项挑战。在内镜下,可用冷器械或激光切开喉蹼,可应用丝裂霉素C,并可在前连合处插入硅橡胶支撑物。在外部,需要进行环甲膜切开术并放置硅橡胶支撑物;对于较厚的喉蹼,可插入前部软骨移植物。无论采用何种技术,主要问题是复发。
