Thirty-four patients with tumors in the conchal bowl were treated with Mohs micrographic surgery. Twenty-six patients had basal cell carcinoma and 8 patients had squamous cell carcinoma. Thirty-three of 34 patients achieved a tumor-free margin during initial therapy. All patients remain free of recurrence and metastasis at an average follow-up period of 2.9 years. Thirty-three of 34 patients were allowed to heal by second intention. Only one patient required reconstruction to avoid stenosis of the external auditory canal.

“…Cancers in this location spreading deep into the EAC require very precise extirpation after accurate visualization, thus as wide as possible access to the operating field. We recommend aggressive and multidisciplinary treatment including a laryngologist and a plastic surgeon, similarly to other authors [3,19,27]. We implemented the retroauricular approach in cases with extension of the tumours from the auricle to the EAC.…”

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)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016)(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.

Epidermal Carcinoma of the Conchal Bowl: Creation of a Multidisciplinary Pathway Approach

Background Malignant neoplasms of the auricle make up 6% of all skin cancers. Management of cutaneous neoplasms of the conchal bowl presents a unique challenge in visualizing and defining margins that may extend into the external auditory canal (EAC). Objectives The objective of this study was to create a multidisciplinary pathway for cutaneous carcinoma of the conchal bowl extending into the EAC. Methods We present a series of patients that were referred to dermatology or otolaryngology, with cutaneous neoplasms arising in the conchal bowl. A consensus approach from otolaryngology and dermatology, for evaluation and treatment, was created based on evaluation of these cases, and review of the otolaryngology and dermatology literature, in collaboration between the two specialties. Results Initial evaluation should be done by both dermatology and otolaryngology, with otomicroscopic evaluation of the canal. Imaging is recommended for lesions that approach the EAC, for bony and soft tissue spread. Excision of the tumor with Mohs micrographic surgery to achieve clearance in the conchal bowl should be performed initially. If extension into the external auditory meatus is present, otolaryngology would proceed with en bloc resection. Repair is dictated by the defect, with both specialties involved in follow-up. Conclusions In collaboration between dermatology and otolaryngology, and following review of the literature, a pathway was created to manage skin cancer of the conchal bowl. This resulted in a stepwise approach for evaluation and management, ensuring that patients have a streamlined pathway for the treatment of these lesions.
