Objectives/Hypothesis To determine if epidemiologic differences exist between patients with oral tongue carcinoma compared to tumors arising from other oral cavity subsites, and the relationship between primary site and in‐hospital mortality, postoperative complications, length of stay, and costs in patients undergoing surgery for oral cavity cancer. Study Design Retrospective cross‐sectional study. Methods The Nationwide Inpatient Sample was analyzed for patients who underwent an ablative procedure for a malignant oral cavity neoplasm in 2001 to 2008 using cross‐tabulations and multivariate regression modeling. Results Overall, there were 45,071 patients treated surgically for oral cavity cancer, with oral tongue cancer comprising 35% of all oral cavity tumors. Patients with oral tongue cancer were significantly more likely to be female (odds ratio [ OR ] = 1.4) and undergo neck dissection ( OR = 1.4), and significantly less likely to be black ( OR = 0.4), over 40 years of age ( OR = 0.4), have Medicaid payer status ( OR = 0.7), advanced comorbidity ( OR = 0.7), receive care at a teaching hospital ( OR = 0.5), and undergo pedicled or free flap reconstruction ( OR = 0.6, P < .001). Oral tongue primary site was not associated with in‐hospital mortality or surgical complications, but was significantly associated with a reduced incidence of medical complications ( OR = 0.8, P = .005). After controlling for all other variables, oral tongue primary site disease was associated with a significantly reduced length of hospitalization and hospital‐related costs. Conclusions Oral tongue cancer is associated with a distinct epidemiologic profile compared to other oral cavity cancer subsites, and is associated with lower postoperative morbidity, length of hospitalization, and hospital‐related costs. Further investigation is warranted to determine if biologic factors underlie these observations. Level of Evidence 2c. Laryngoscope , 2013
