RESULTS
In this study, a total number of 11 patients (4 males and 7 females) aged from 36 to 69 years, with bilateral severe or profound SNHL after chemoradiotherapy for NPC, who underwent CI, were enrolled. All patients had suffered from hearing loss after standard chemoradiotherapy prior to CI. All patients were regularly followed up postoperatively, with a follow-up duration ranging from 6 to 60 months, with an average of 29 months (Table 1).
