External auditory meatus and/or conchal bowl reconstruction with postauricular island flap in patients with Basal Cell Carcinoma or Squamous Cell Carcinoma.

Aims: Presenting our clinical experience with the postauricular island flap (pif) and estimation of the results following partial external auditory canal (eac) and/or auricular conchal bowl reconstructions with the pif in patients after carcinoma resections.
Methods: We have analyzed postoperative results of 19 patients after auricular conchal bowl (11), or auricular conchal bowl and eac (8) reconstructions with pif, following malignant tumor resections, between 2000-2015. The patients were followed-up and evaluated in respect of early and long-term results after surgical treatment considering plastic surgeon's and patient's opinion.
Results: The cancers were completely excised in all patients, and there were no recurrences within at least 2 years of follow-up. The observed complications after reconstructions comprised venous congestion in five cases (26.3 %), pinning of the operated ear in four patients (21 %), prominent earlobe in three (15.8 %), and eac constriction in three cases (15.8 %). Postoperative result was very good in all cases (both in the opinion of plastic surgeon and patients), except patients with pinning of the operated ear, prominent earlobe (moderately satisfied). Conclusions 1. Combined operations involving postauricular island flap reconstructions after partial (external auditory meatus and/or auricular conchal bowl) resections allowed for complete removal of malignant tumors with no evidence of recurrence, and also preservation of proper conchal shape in the reconstructed ear. 2. Retroauricular approach in cases with cancer involvement of the external auditory meatus allowed for proper visualization and estimation of lesions extent, as well as adequate surgical access.
