Auricular appendices are not unusual, but doubling of the pinna is rare. There is still a controversy if these are derivates from the first or the second branchial arch.
The case of a 3 year old girl is described with doubling of the pinna and hemi facial atrophia. The second pinna was on third of the orthotop regular auricle. It seemed to come from the tragus anlage i. e. originating from the first otic hillock.
The accessory pinna was resected, an aesthetic result could be achieved.
Morphology and position of accessory pinnas arise again the question of the origin of the auricular hillocks. This case supports the opinion of Otto that the first hillock only belongs to the first branchial arch and the major part of the auricle is originating from the hillock 2-6 i. e. to the second branchial arch.
耳廓附件并不罕见，但耳廓重复畸形却很罕见。这些附件是源自第一鳃弓还是第二鳃弓仍存在争议。
描述了一名3岁女孩的病例，其存在耳廓重复畸形和半侧面部萎缩。第二个耳廓位于正常耳廓位置的三分之一处。它似乎起源于耳屏原基，即起源于第一耳丘。
切除了副耳廓，获得了美观的效果。
副耳廓的形态和位置再次引发了耳丘起源的问题。该病例支持奥托的观点，即第一耳丘仅属于第一鳃弓，而耳廓的大部分起源于耳丘2 - 6，即第二鳃弓。
