在胚胎发育过程中,第一、二鳃弓突起融合不全,第一鳃沟封闭不全或鳃裂残余,有可能演化成耳前瘘管或第一鳃裂瘘管和囊肿。先天性耳前瘘管较常见,且多为单侧性;第一鳃裂瘘管很少见。本文就我院在1961～1981年间用手术治疗的先天性耳前瘘管109例和第一鳃裂瘘管3例综合报告于后.临床资料先天性耳前瘘管109例(123耳)中,男70例,女39例;年龄4～42岁,以21～30岁为最多;左侧72耳,右侧51耳。瘘管口均在耳轮脚前方,其中双侧有28例,为对称性。挤压瘘管有腐乳状带臭味的或
In the process of embryonic development, the first and second gill arch fusion incomplete, the first gill ditch incomplete or branchial cleft, it may evolve into pre-otitis or first branchial fistula and cysts. Congenital ear fistula is more common, and mostly unilateral; first branchial fistula is very rare. This article on our hospital in 1961 to 1981 with surgical treatment of congenital preecological fistula 109 cases and the first branchial fistula 3 cases reported later in the clinical data congenital anterior fistula 109 cases (123 ears), male 70 Cases, 39 females; aged 4 to 42 years old, 21 to 30 years of age as the most; left ear 72 ears, right ear 51 ears. Fistula mouth are in front of the helix foot, including bilateral in 28 cases, symmetry. Squeeze the fistula with decadent or odor
