BACKGROUND: The frequency of postoperative complications is used as an indicator of surgical quality; however, comparison of outcomes is hampered by a lack of agreement on the definition of complications and their severity. A standard grading system for surgical complications is necessary to improve the quality of clinical research and reporting in head and neck reconstruction.
METHODS: The aim of this study was to compare postoperative morbidity after microvascular head and neck reconstruction between patients with versus without a history of prior radiation therapy (RT) by using the Clavien-Dindo classification. A group of 274 patients was divided into two cohorts based on the history of prior RT: the RT group included 79 patients and the non-RT group included 195 patients. Postoperative (30-day) complications were compared between the groups with a nonstandardized evaluation system and the Clavien-Dindo classification.
RESULTS: The grades of complications according to the Clavien-Dindo classification were significantly higher in the RT group than in the non-RT group. The frequency of postoperative complications did not differ significantly between the groups according to the nonstandardized evaluation system.
CONCLUSIONS: The Clavien-Dindo classification could serve as a useful, highly objective tool for grading operative morbidity after microvascular head and neck reconstruction when comparing similar defects and methods of reconstruction. Widespread use of the Clavien-Dindo classification system would allow adequate comparisons of surgical outcomes among different surgeons, centers, and therapies.
