Objective: To review an institutional experience with the surgical and clinical management of acquired middle ear cholesteatoma in patients with ectrodactyly, ectodermal dysplasia, cleft lip/palate (EEC) syndrome.

Study Design: Retrospective chart review.

Setting: Tertiary referral center.

Patients: Eight patients with medical history significant for EEC syndrome who underwent surgery for acquired middle ear cholesteatoma between 1996 and 2016.

Intervention(s): Appropriate surgical interventions at the time of admission.

Main Outcome Measure(s): History of ventilation tube insertion, status of the contralateral ear, surgical technique, cholesteatoma recidivism, presence of postoperative external auditory canal stenosis, pre and postoperative audiograms.

Results: Cholesteatoma was diagnosed in all patients, 3 (37.5%) unilateral and 5 (62.5%) bilateral, totalizing 13 ears. Six ears (46.2%) underwent a canal wall up mastoidectomy but required conversion to a canal wall down technique in a second procedure due to recurrent cholesteatoma. In the remaining seven ears (53.8%) a canal wall down mastoidectomy was performed. Of all meatoplasty performed, seven (53.8%) evolved with stenosis of the external auditory canal.

Conclusions: Our results suggest that most patients with EEC syndrome and middle ear cholesteatoma should be considered for a canal wall down mastoidectomy due to extensive disease and a high rate of recidivism. In addition, a high percentage of postoperative stenosis of the external auditory canal was found in this group.
