Background: We aimed to compare unstimulated saliva flow using 3‐minute modified Schirmer test (MST) following bilateral vs unilateral radiotherapy (RT) in oropharyngeal carcinoma (OPC). Methods: We reviewed OPC patients treated with definitive intensity‐modulated radiation therapy (IMRT) between 2011 and 2017. MST was measured at baseline, 1‐/6‐/12‐/24‐month post‐RT. MST values were compared between bilateral‐RT vs unilateral‐RT groups. Multivariable logistic regression analysis (MVA) identified predictors of hyposalivation (MST < 25 mm). Results: Total 498 bilateral‐RT and 36 unilateral‐RT patients were eligible. The MST values at 1‐/6‐/12‐/24‐month post‐RT were all significantly reduced from baseline for the entire cohort. Baseline unilateral‐RT and bilateral‐RT MST values (in mm) were similar (P =.2), but much higher for unilateral‐RT 1‐month (mean: 19.1 vs 13.0, P =.03), 6‐month (20.5 vs 9.3, P <.001), 12‐month (20.1 vs 11.9, P <.01), and 24‐month post‐RT (22.2 vs 13.9, P =.04). MVA confirmed that unilateral RT reduced the likelihood of hyposalivation vs bilateral RT (OR 2.36, P =.006). Conclusion: Unilateral RT reduces unstimulated salivary flow in OPC patients.
