The Relationship between the Characteristics of Tinnitus and the Hearing Curative Effect of Sudden Deafness

Abstract

<b><i>Background:</i></b> Tinnitus is the most common complication of sudden deafness. There are many studies on tinnitus and tinnitus as a prognostic factor for sudden deafness. <b><i>Summary:</i></b> We collected 285 cases (330 ears) of sudden deafness to investigate the relationship between tinnitus psychoacoustic characteristics and the hearing curative effective rate. The hearing curative effective rate was analyzed and compared between the patients whether it is accompanied by tinnitus, with different tinnitus frequency and different tinnitus loudness. <b><i>Key Messages:</i></b> Patients with tinnitus frequency (125–2,000 Hz) and no tinnitus have better hearing efficacy, and those with high frequency tinnitus (3,000–8,000 Hz) have worse hearing efficacy. Test the tinnitus frequency of patients in the initial stage of sudden deafness has some guiding significance for the evaluation of hearing prognosis.

Tinnitus characteristics in patients with idiopathic sudden sensorineural hearing loss and acute tinnitus

“…Increased neural synchronization may result in a sound sensation in the absence of external sound stimuli 17,18 . Therefore, the frequency of acute tinnitus in patients with ISSHL is usually consistent with the frequency of hearing loss due to this mechanism 19 . However, the frequency of chronic tinnitus might differ due to reorganization of the auditory cortex 5 …”

“…17,18 Therefore, the frequency of acute tinnitus in patients with ISSHL is usually consistent with the frequency of hearing loss due to this mechanism. 19 However, the frequency of chronic tinnitus might differ due to reorganization of the auditory cortex. 5 In the present study, improvement in acute tinnitus was seen in patients with light handicap scores, while aggravation of acute tinnitus was seen in patients with severe and catastrophic handicap scores.…”
