Abstract
INTRODUCTION: Cancers of the auricle and the external auditory canal (EAC) remain a relevant oncological problem. AIM: Presentation of the results after resections of conchal bowl and EAC carcinoma (with or without radical mastoid surgery) and after reconstructions (postauricular island flap - PIF). MATERIAL AND METHODS: We analysed results of 37 patients with cancers of the auricular conchal bowl and EAC after tumour resection and reconstruction (2000-2017). RESULTS: The cancers were completely excised in all patients, with no recurrences within at least 5 years after surgery. We noted venous congestion in 22 (59.4%) cases, pinning of the operated ear in 18 (48.6%), prominent earlobe in 14 (37.8%), and EAC constriction in 6 (16.2%) cases treated without radical mastoid surgery. CONCLUSIONS: Retroauricular approach in cancer of the auricular concha and EAC allowed for accurate evaluation of the tumour extent and proper surgical access, which facilitated complete removal of the tumour. Use of radical mastoid operation with conchal bowl resection and PIF reconstruction in patients with aquamous cell carcinoma or infiltrating basal cell carcinoma of auricular concha and osseous EAC resulted in cancer extirpation and good aesthetic outcomes, despite minor functional consequences. In these cancers mastoidectomy offered a wider access to determine the radicality of oncological resection.
