Three pure-tone audiometric and tympanometric records were taken from each subject. The first records were taken before RME (T1), the second after maxillary expansion (T2) (mean = 0.83 months), and the third after retention (mean = 6 months) and fixed appliance treatment (approximately 2 years) periods (T3). The data were analyzed by means of analysis of variance (ANOVA) and least significant difference (LSD) tests.<\/jats:p>\n               <jats:p>Results: Hearing levels of the patients were improved and air-bone gaps decreased at a statistically significant level (P &amp;lt; .001) during active expansion (T2\u2013T1) and the retention and fixed appliance treatment (T2\u2013T3) periods. Middle ear volume increased in all observation periods. However, a statistically significant increase was observed only in the T2\u2013T3 period. No significant change was observed in the static compliance value.<\/jats:p>\n               <jats:p>Conclusions: The hypothesis is rejected. RME treatment has a positive and statistically significant effect on both improvements in hearing and normal function of the eustachian tube in patients having transverse maxillary deficiency and CHL.<\/jats:p>","DOI":"10.2319\/050407-217.1","type":"journal-article","created":{"date-parts":[[2007,11,7]],"date-time":"2007-11-07T22:31:36Z","timestamp":1194474696000},"page":"409-414","source":"Crossref","is-referenced-by-count":29,"title":["Effects of Rapid Maxillary Expansion on Conductive Hearing Loss"],"prefix":"10.2319","volume":"78","author":[{"given":"Nihat","family":"Kilic","sequence":"first","affiliation":[{"name":"a\u2009Assistant Professor, Department of Orthodontics, Faculty of Dentistry, Ataturk University, Erzurum, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ali","family":"Kiki","sequence":"first","affiliation":[{"name":"a\u2009Assistant Professor, Department of Orthodontics, Faculty of Dentistry, Ataturk University, Erzurum, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H\u00fcsamettin","family":"Oktay","sequence":"first","affiliation":[{"name":"b\u2009Professor, Department of Orthodontics, Faculty of Dentistry, Ataturk University, Erzurum, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Erol","family":"Selimoglu","sequence":"first","affiliation":[{"name":"c\u2009Professor, Department of Otorhinolaryngology, Medical Faculty, In\u00f6n\u00fc University, Malatya, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1164","reference":[{"key":"2020042120431196700_i0003-3219-078-03-0409-b1","article-title":"The Heart of Listening: A Visionary Approach to Craniosacral Work.","author":"Milne"},{"key":"2020042120431196700_i0003-3219-078-03-0409-b2","first-page":"200","article-title":"The treatment of maxillary deficiency by opening the midpalatal suture.","volume":"35","author":"Haas","year":"1965","journal-title":"Angle Orthod"},{"key":"2020042120431196700_i0003-3219-078-03-0409-b3","doi-asserted-by":"crossref","first-page":"41","DOI":"10.1016\/0002-9416(70)90127-2","article-title":"Skeletal and dental changes accompanying rapid midpalatal suture opening.","volume":"58","author":"Wertz","year":"1970","journal-title":"Am J Orthod"},{"key":"2020042120431196700_i0003-3219-078-03-0409-b4","doi-asserted-by":"crossref","first-page":"3","DOI":"10.1016\/0889-5406(87)90202-2","article-title":"Maxillary expansion: clinical implications.","volume":"91","author":"Bishara","year":"1987","journal-title":"Am J Orthod Dentofacial Orthop"},{"key":"2020042120431196700_i0003-3219-078-03-0409-b5","doi-asserted-by":"crossref","first-page":"325","DOI":"10.1016\/0002-9416(81)90294-3","article-title":"Conductive hearing loss and rapid maxillary expansion.
