Hearing loss directly derived from idiopathic SSNHL is important for understanding underlying pathogenesis and outcomes. We assessed the usefulness of evaluating hearing loss and recovery of idiopathic SSNHL on the basis of estimated hearing loss. The study included 115 patients whose characteristics and outcomes of hearing loss were investigated. The effects of vertigo\/dizziness and age on hearing thresholds before\/after treatment, nonaffected ear threshold, estimated hearing loss, improvement of hearing loss, and estimated remaining hearing loss were investigated. Vertigo\/dizziness was a significant prognostic factor for hearing. In vertigo\/dizziness patients, significantly more severe hearing loss and poorer improvement of hearing loss were observed above 500 Hz and below 1000 Hz, respectively. Severe hearing disorder remained at all frequencies. Conversely, post-treatment thresholds were significantly higher in the older population (\u226565 years), although no differences in pretreatment thresholds were observed between the younger (\u226464 years) and older populations. However, on the basis of nonaffected ear thresholds, previously existing hearing loss could have influenced the outcome. Thus, comparison of hearing outcomes between affected and nonaffected ears is essential for understanding hearing loss and outcomes in idiopathic SSNHL cases with existing hearing disorder.<\/jats:p>","DOI":"10.3390\/audiolres12050048","type":"journal-article","created":{"date-parts":[[2022,9,1]],"date-time":"2022-09-01T01:50:51Z","timestamp":1661997051000},"page":"476-484","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Evaluation of the Recovery of Idiopathic Sudden Sensorineural Hearing Loss Based on Estimated Hearing Disorders"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0000-1041","authenticated-orcid":false,"given":"Tadashi","family":"Nishimura","sequence":"first","affiliation":[{"name":"Department of Otolaryngology-Head and Neck Surgery, Nara Medical University, 840 Shijo-cho, Kashihara 634-8522, Nara, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0811-1405","authenticated-orcid":false,"given":"Tadao","family":"Okayasu","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology-Head and Neck Surgery, Nara Medical University, 840 Shijo-cho, Kashihara 634-8522, Nara, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chihiro","family":"Morimoto","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology-Head and Neck Surgery, Nara Medical University, 840 Shijo-cho, Kashihara 634-8522, Nara, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sakie","family":"Akasaka","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology-Head and Neck Surgery, Nara Medical University, 840 Shijo-cho, Kashihara 634-8522, Nara, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tadashi","family":"Kitahara","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology-Head and Neck Surgery, Nara Medical University, 840 Shijo-cho, Kashihara 634-8522, Nara, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroshi","family":"Hosoi","sequence":"additional","affiliation":[{"name":"MBT (Medicine-Based Town) Institute, Nara Medical University, 840 Shijo-cho, Kashihara 634-8522, Nara, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"624","DOI":"10.1002\/lary.22480","article-title":"Systematic review and meta-analysis of the risk factors for sudden sensorineural hearing loss in adults","volume":"122","author":"Lin","year":"2012","journal-title":"Laryngoscope"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"92","DOI":"10.1067\/mhn.2003.50","article-title":"Diagnosis and treatment of sudden-onset sensorineural hearing loss: A study of 51 patients","volume":"128","author":"Zadeh","year":"2003","journal-title":"Otolaryngol.
