Isolated semicircular canal dysfunction has been correlated with several peripheral and central vestibular etiologies. Selective\n bilateral posterior canal dysfunction is a trend seen in the clinical setting but less commonly reported in the medical literature. <jats:bold>Purpose<\/jats:bold>\u2003The purpose of this work is to explore the clinical profile of bilateral posterior canal dysfunction along with other presenting factors\n such as hearing loss, increased age, and associated nystagmus patterns. <jats:bold>Method<\/jats:bold>\u2003A case series of three patients (age range: 67\u201074 years) is presented to illustrate the similarities and clinical associations between vestibular and balance history, medical history, and\n vestibular test results. <jats:bold>Results<\/jats:bold>\u2003All three patient cases presented with below reference range posterior semicircular canal function on video head impulse testing. Two patients also presented with down-beating nystagmus, and two endorsed subjective hearing loss while the third\n presented with presbycusis. <jats:bold>Conclusion<\/jats:bold>\u2003Selective bilateral posterior canal dysfunction in association with advanced age, presbycusis, and signs of down-beating nystagmus may be associated with vestibulocochlear degenerative processes. Yet, central disorders, technical and patient\n factors may present clinical challenges to elucidate the cause.<\/jats:p>","DOI":"10.1055\/s-0044-1791208","type":"journal-article","created":{"date-parts":[[2024,12,16]],"date-time":"2024-12-16T23:44:03Z","timestamp":1734392643000},"page":"144-152","source":"Crossref","is-referenced-by-count":1,"title":["Selective Bilateral Posterior Canal Dysfunction: A Case Series Investigation into the Clinical Trends and Associative Factors"],"prefix":"10.3766","volume":"35","author":[{"given":"Evalena R.","family":"Behr","sequence":"first","affiliation":[{"name":"Section of Audiology, Vestibular and Balance Disorders Program, Head and Neck Department, Integrated Surgical Institute, Cleveland Clinic, Cleveland, Ohio"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Julie A.","family":"Honaker","sequence":"additional","affiliation":[{"name":"Section of Audiology, Vestibular and Balance Disorders Program, Head and Neck Department, Integrated Surgical Institute, Cleveland Clinic, Cleveland, Ohio"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2087","reference":[{"issue":"03","key":"ref1","doi-asserted-by":"crossref","first-page":"288","DOI":"10.1016\/j.anl.2016.07.020","article-title":"Vestibular neuritis: involvement and long-term recovery of individual semicircular canals","volume":"44","author":"B B\u00fcki","year":"2017","journal-title":"Auris Nasus Larynx"},{"issue":"05","key":"ref2","doi-asserted-by":"crossref","first-page":"471","DOI":"10.1080\/00016489.2021.1884287","article-title":"Video-head impulse test in superior canal dehiscence","volume":"141","author":"P Mukherjee","year":"2021","journal-title":"Acta Otolaryngol"},{"issue":"02","key":"ref3","doi-asserted-by":"crossref","first-page":"319","DOI":"10.1016\/j.amjoto.2018.12.005","article-title":"Isolated horizontal canal hypofunction differentiating a canalith jam from an acute peripheral vestibular loss","volume":"40","author":"A Castellucci","year":"2019","journal-title":"Am J Otolaryngol"},{"issue":"03","key":"ref4","doi-asserted-by":"crossref","first-page":"153","DOI":"10.7874\/jao.2021.00297","article-title":"Spontaneous upbeat nystagmus and selective anterior semicircular canal hypofunction on video head impulse test: a new variant of canalith jam?","volume":"26","author":"A Castellucci","year":"2022","journal-title":"J Audiol Otol"},{"key":"ref5","doi-asserted-by":"crossref","first-page":"264","DOI":"10.3389\/fneur.2018.00264","article-title":"Central lesions with selective semicircular canal involvement mimicking bilateral vestibulopathy","volume":"9","author":"L Chen","year":"2018","journal-title":"Front Neurol"},{"issue":"04","key":"ref6","doi-asserted-by":"crossref","first-page":"573","DOI":"10.1097\/MAO.0000000000002995","article-title":"Which inner ear disorders lie behind a selective posterior semicircular canal hypofunction on video head impulse test?","volume":"42","author":"A Castellucci","year":"2021","journal-title":"Otol Neurotol"},{"issue":"08","key":"ref7","doi-asserted-by":"crossref","first-page":"1532","DOI":"10.1016\/j.clinph.2017.04.029","article-title":"Association of posterior semicircular canal hypofunction on video-head-impulse testing with other vestibulo-cochlear deficits","volume":"128","author":"A A Tarnutzer","year":"2017","journal-title":"Clin Neurophysiol"},{"issue":"03","key":"ref8","doi-asserted-by":"crossref","first-page":"203","DOI":"10.3233\/VES-200703","article-title":"Vestibular function analysis of sudden sensorineural hearing loss with dizziness","volume":"30","author":"J-Y Lee","year":"2020","journal-title":"J Vestib Res"},{"issue":"01","key":"ref9","doi-asserted-by":"crossref","first-page":"242","DOI":"10.1097\/AUD.0000000000001129","article-title":"Vestibular mapping assessment in idiopathic sudden sensorineural hearing loss","volume":"43","author":"H W Seo","year":"2022","journal-title":"Ear Hear"},{"issue":"01","key":"ref10","first-page":"15","article-title":"Reduction in posterior semicircular canal gain by age in video head impulse testing.
