Survival differed significantly between never smokers and ever smokers with SCCHN. These results are not substantively explained by differences in cancer-associated symptoms or alcohol use, but the CIs are wide and some imprecision remains. Regardless, possible fundamental differences in SCCHN between ever smokers and never smokers may exist, and further molecular characterization of these tumors is needed to determine whether biologic differences needing targeted therapies exist.

To compare the survival rates of patients 40 years or younger and diagnosed with squamous cell carcinoma of the head and neck (SCCHN) with those of patients older than 40 years who underwent the same treatment. In 2 previous matched-pair analyses, the patients had been matched for tumor stage, site, sex, and date of presentation but not type of treatment. Methods: Between 1995 and 2001, 46 patients 40 years or younger participated in a prospective epidemiologic study that included more than 500 patients newly diagnosed with SCCHN. We matched each of these patients by sex, race, tumor site, overall stage, and treatment modality with 2 patients older than 40 years. Ultimately, 31 of the younger patients were matched with 62 of the older patients. Survival analysis was performed using Cox proportional hazard models and accounting for the matched trios. Results: There was no difference in overall, diseasespecific, or recurrence-free survival rates between the patients who were 40 years or younger and those older than 40 years. Furthermore, matched survival analysis did not demonstrate a difference in overall survival rate (risk ratio [RR], 0.71; 95% confidence interval [CI], 0.22-2.29; P=.56), disease-free survival rate (RR, 0.83; 95% CI, 0.20-3.33; P =.79), or time to recurrence (RR, 1.46; 95% CI, 0.50-4.23; P =.49), and was not affected by adjustment for medical comorbidities or the severity of cancerassociated symptoms. Conclusions: We found no evidence of a difference in the survival rates of patients with SCCHN who were 40 years or younger or older than 40 years and underwent similar treatment at our institution.

Patients with all forms of traumatic conductive hearing loss can be initially managed conservatively. Even suspected ossicular chain disruptions have a high rate of spontaneous reparation. Surgical intervention for perforation or conductive hearing loss should be undertaken in the rare cases when these conditions persist greater than 6 months.
