Objective: It is increasingly important to identify risk factors for COVID-19-associated mortality to provide access to early treatment. This study aimed to investigate the relationship between COVID-19 severity and laboratory data and demographic characteristics of hospitalized patients and to identify factors predicting mortality in COVID-19.
Materials And Methods: The study is a retrospective and single-center study.
Purpose: This study analyzed the late ear complications of radiotherapy for nasopharyngeal cancer (NPC) and compared the conventional and intensity-modulated radiotherapy (2D-RT and IMRT, respectively).
Methods: At 2-21 years after the end of NPC treatment, 104 ears of 52 patients were evaluated with the otoscopic examination, pure tone audiometry test, tympanometry, and subjective complaints by being blinded to the radiotherapy technique.
Results: There were no differences in terms of the pathology of the external, middle or inner ear, air and bone-conduction hearing thresholds, and the air-bone (A-B) gap at 500, 1000, 2000, and 4000 Hz, and tympanometry types between 2D-RT and IMRT groups (p > 0.
