title: Use of the subgaleal fascia to construct the auditory canal in microtia associated with aural atresia. A preliminary report.
abstract: In this paper we introduce the use of a subgaleal flap to construct the auditory canal in cases of microtia associated with aural atresia. The anatomy, the vascularisation, and the nomenclature of the different planes that constitute the temporal region are wellknown. The subgaleal fascia, also referred to as the loose areolar fascia has been until now the less surgically exploited of these planes. Nevertheless, it has a structure and a vascularisation that enables it to be dissected and used surgically. The subgaleal flap used to line the neoauditory canal drilled into the bone provides a vascular bed that greatly improves the quality of the skin graft and supports the tympanoplasty. The procedure is done while the ear is being raised, which constitutes the second stage of the two-stage ear reconstruction. This new approach has been used on 22 ears. A preliminary analysis of the results shows that construction of the auditory canal has been improved.
