Overview of time from RT initiation to sensorineural hearing loss (SNHL) onset (Chang grade > 0) and progression (an increase in Chang grade from SNHL onset to the most recent evaluation). All 33 patients with SNHL were sorted by duration of follow-up. Patients with shorter follow-up periods were placed on the left side of the plot, and those with longer follow-up were placed on the right side. For all patients and ears in the plot, an arbitrary 100 days were added to the last evaluation so that the Chang grade at last evaluation can be visualized. L, left; R, right; RT, radiation therapy.
