Abstract

Chondroradionecrosis (CRN) is an uncommon but significant complication of laryngeal radiotherapy that presents a diagnostic challenge to clinicians through its similarity in presentation to cancer recurrence.Two hundred ninety-four patients underwent primary, adjuvant, or salvage radiation for laryngeal cancer from 1991 to 2015 at the University of Wisconsin. Medical records were reviewed to identify and characterize patients with a diagnosis of CRN.Of the 294 patients, 7 cases (2.4%) of CRN were identified. Development of CRN was associated with the presence of cartilage invasion by tumor (p = .038) and ongoing alcohol use postradiotherapy (p = .036). Additionally, a trend between development of CRN and ongoing smoking postradiotherapy was observed (p = .067).The diagnosis of CRN is challenging, and the likelihood of successful resolution is modest. A high premium should be placed on efforts directed at prevention, such as tobacco and alcohol cessation. © 2017 Wiley Periodicals, Inc. Head Neck 39: 1189-1194, 2017.
