Introduction Surgical management of oral cavity carcinoma involves composite resection with reconstruction. Comorbidities increase the risk of perioperative complications. Objective stratification is important for uneventful recovery. The Charlson Comorbidity Index and the Washington University Head and Neck Comorbidity Index were used to assess perioperative morbidity and mortality. Materials and methods This was a prospective study of 531 patients with head and neck squamous cell carcinoma who were treated between January 2014 and December 2017. Patients’ comorbidity scores on the Charlson Comorbidity Index and Washington University Head and Neck Comorbidity Index were recorded. Results The median age of the cohort was 49 years. Median Charlson Comorbidity Index score was 3 and Washington University Head and Neck Comorbidity Index was 0. There were five mortalities with a Charlson Comorbidity Index score of 4 or more. Fifteen patients had either infection, leak or postoperative bleeding. A Charlson Comorbidity Index of 4 or more was associated with higher event rate and poor overall survival (p=0.001) Conclusion Higher Charlson Comorbidity Index score is associated with increased incidence of peri-operative morbidity and mortality, while the Washington University Head and Neck Comorbidity Index is a poor predictor of the same.
Introduction Microvascular reconstruction is the gold standard for reconstruction in oral cavity cancers. Age and comorbidities determine the type of reconstruction. We aimed to analyse the impact of high-risk comorbidities on perioperative morbidity. Methods This is a retrospective study of 317 patients undergoing microvascular reconstruction from January 2014 to December 2017. High risk patients were based on age, American Society of Anaesthesiologists (ASA) grade (III/IV) and Charlson comorbidity index (CCI) score >4; overall, 73 out of 317 patients were evaluated. Results Median age was 59 years. Five patients (6.8%) had complete flap failures and seven (9.5%) had minor complications (wound breakdown, bleeding, wound dehiscence, partial flap loss). ASA score of IV was significantly associated with morbidity while age >65 years and CCI >4 was not associated. The overall flap success rate was 93.2%. Conclusions A high-risk population has nearly similar outcomes for microvascular reconstruction as a younger age group. High ASA score adversely affects surgery-related outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
