Only those with normal cochlear function based on conventional pure tone audiometry (250\u2009Hz to 8\u00a0kHz) were included. They were further tested for hearing at extended high frequencies of up to 16\u2009kHz. The severity of tinnitus was tested using a tinnitus questionnaire.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The prevalence of extended high frequency hearing loss in the normal cochlear function CSOM patients with tinnitus was 81.8% (95% CI 74.5%, 89.1%), whereas the prevalence in the tinnitus negative group was 30.0% (95% CI 21.3%, 38.7%). There was a significant association between extended high frequency hearing loss and tinnitus in CSOM patients (<jats:italic>P<\/jats:italic>\u2009&lt;\u2009.001). The average thresholds were significantly higher in the tinnitus group at all extended high frequencies tested with an increasing trend of significance toward the higher frequencies. However, this study did not observe any association between the severity of tinnitus and extended high frequency hearing loss.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The development of tinnitus among normal cochlear function CSOM patients indicates that the damage has occurred at a higher frequency level. However, the severity of tinnitus does not predict the degree of higher frequency hearing loss. Therefore, the presence of tinnitus warrants more aggressive monitoring and treatment to prevent sensorineural hearing loss from developing into the speech frequencies.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of Evidence<\/jats:title><jats:p>4.<\/jats:p><\/jats:sec>","DOI":"10.1002\/lio2.651","type":"journal-article","created":{"date-parts":[[2021,9,4]],"date-time":"2021-09-04T10:39:15Z","timestamp":1630751955000},"page":"1137-1141","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Extended high frequency hearing loss in tinnitus\u2010positive chronic suppurative otitis media patient"],"prefix":"10.1002","volume":"6","author":[{"given":"Nur Syazwani","family":"Mohd Salehuddin","sequence":"first","affiliation":[{"name":"Department of Otorhinolaryngology, School of Medical Sciences Universiti Sains Malaysia  Kubang Kerian Kelantan Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5056-6446","authenticated-orcid":false,"given":"Mohd Khairi","family":"Md Daud","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, School of Medical Sciences Universiti Sains Malaysia  Kubang Kerian Kelantan Malaysia"},{"name":"Hospital Universiti Sains Malaysia  Kubang Kerian Kelantan Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nik Adilah","family":"Nik Othman","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, School of Medical Sciences Universiti Sains Malaysia  Kubang Kerian Kelantan Malaysia"},{"name":"Hospital Universiti Sains Malaysia  Kubang Kerian Kelantan Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Normastura","family":"Abd Rahman","sequence":"additional","affiliation":[{"name":"School of Dental Sciences, Health Campus, Universiti Sains Malaysia  Kubang Kerian Kelantan Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2021,9,4]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.2165\/00002018-200326060-00003"},{"issue":"5","key":"e_1_2_7_3_1","first-page":"559","article-title":"Sensorineural hearing loss in chronic suppurative otitis media","volume":"20","author":"Md Daud MK","year":"2013","journal-title":"Int Med J"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.19082\/3823"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.eurger.2015.01.004"},{"issue":"2","key":"e_1_2_7_6_1","first-page":"71","article-title":"Development and phychometric validation of a new tinnitus questionnaire for clinical use","volume":"26","author":"Zakaria MN","year":"2017","journal-title":"Aud Vest Res"},{"issue":"2","key":"e_1_2_7_7_1","first-page":"3","article-title":"How safe is safe ear?
