Although trismus is commonly observed in patients with ZMC fracture, continuous follow\u2010up examinations of their degree of mouth opening have rarely been documented. The aim of this retrospective study was to determine the incidence and clinical significance of ZMC fracture involving the glenoid fossa or articular eminence of the TMJ with an emphasis on trismus. The medical and computed tomography (CT) imaging data of 28 patients with ZMC fracture treated by oral and maxillofacial surgeons (OMFSs) (OMFS group) and 174 patients with ZMC fracture treated by surgeons other than OMFSs (non\u2010OMFS group) between May 2002 and May 2006 were reviewed. Maximal interincisal opening (MIO) less than 35 mm or three\u2010finger width was considered limited mouth opening and indicative of trismus. Preoperative CT imaging data indicated that about 64% (18\/28) and 50% (87\/174) of the patients in the OMFS and non\u2010OMFS groups, respectively, had a ZMC fracture involving the TMJ. Among these OMFS patients, 17 (94.40%) patients had limited mouth opening (MIO range, 7\u201333 mm) preoperatively, which improved markedly postoperatively. Among the non\u2010OMFS patients with such fractures, 42 (48.3%) patients had trismus preoperatively and two retained trismus postoperatively. Lack of proper preoperative CT images, inadequate postoperative follow\u2010up protocol, and\/or neglect by patients and medical staff could influence the outcomes of ZMC fracture involving the TMJ. We make recommendations for reducing the risk of complications subsequent to ZMC fracture involving the TMJ.<\/jats:p><\/jats:sec>","DOI":"10.1016\/j.kjms.2011.11.016","type":"journal-article","created":{"date-parts":[[2012,4,4]],"date-time":"2012-04-04T04:40:18Z","timestamp":1333514418000},"page":"336-340","source":"Crossref","is-referenced-by-count":16,"title":["Incidence and clinical significance of zygomaticomaxillary complex fracture involving the temporomandibular joint with emphasis on trismus"],"prefix":"10.1002","volume":"28","author":[{"given":"Chia\u2010Ming","family":"Chang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Edward C.","family":"Ko","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chu\u2010Chiang","family":"Kao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pei\u2010Ying","family":"Chang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael Y.C.","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2012,4,2]]},"reference":[{"key":"e_1_2_5_2_2","first-page":"445","volume-title":"Peterson's principles of oral and maxillofacial surgery","author":"Bailey J.S.","year":"2004"},{"key":"e_1_2_5_3_2","first-page":"182","volume-title":"Oral and maxillofacial surgery","author":"D'Addario M.","year":"2009"},{"key":"e_1_2_5_4_2","doi-asserted-by":"crossref","first-page":"235","DOI":"10.2214\/ajr.128.2.235","article-title":"Anatomic, clinical, surgical, and radiographic correlation of the zygomatic complex fracture","volume":"128","author":"Gerlock A.J.","year":"1977","journal-title":"Am J Roentgenol"},{"key":"e_1_2_5_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0278-2391(98)90878-3"},{"key":"e_1_2_5_6_2","first-page":"223","article-title":"Pseudoankylosis of the mandible after a fracture of the zygomaticomaxillary complex: report of case","volume":"29","author":"Warson R.W.","year":"1971","journal-title":"J Oral Surg"},{"key":"e_1_2_5_7_2","first-page":"788","article-title":"Pseudoankylosis from fusion of coronoid process and zygomatic arch","volume":"31","author":"Lapeyrolerie F.M.","year":"1973","journal-title":"J Oral Surg"},{"key":"e_1_2_5_8_2","first-page":"665","article-title":"Extracapsular fibrous ankylosis of the mandible after open reduction of a zygomatic arch fracture: report of case","volume":"37","author":"Kellner M.J.","year":"1979","journal-title":"J Oral Surg"},{"key":"e_1_2_5_9_2","volume-title":"Oral and maxillofacial trauma","author":"Fonseca R.J.","year":"2005"}],"container-title":["The Kaohsiung Journal of Medical Sciences"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.elsevier.com\/content\/article\/PII:S1607551X11002713?httpAccept=text\/xml","content-type":"text\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/api.elsevier.com\/content\/article\/PII:S1607551X11002713?httpAccept=text\/plain","content-type":"text\/plain","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1016\/j.kjms.2011.11.016","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,14]],"date-time":"2023-09-14T05:51:25Z","timestamp":1694670685000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1016\/j.kjms.2011.11.016"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012,4,2]]},"references-count":8,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2012,6]]}},"alternative-id":["10.1016\/j.kjms.2011.11.016"],"URL":"https:\/\/doi.org\/10.1016\/j.kjms.2011.11.016","archive":["Portico"],"relation":{},"ISSN":["1607-551X","2410-8650"],"issn-type":[{"value":"1607-551X","type":"print"},{"value":"2410-8650","type":"electronic"}],"subject":[],"published":{"date-parts":[[2012,4,2]]}}}
