We present the case of a newborn who presented with severe, congenital trismus due to brainstem dysgenesis. We describe the course of his investigations, and a multidisciplinary approach to the management of his care and follow-up. To our knowledge, this is one of the earliest reported cases of congenital trismus attributable to brainstem dysgenesis. A literature review was conducted to provide an overview of the differential pathogenesis as it presents in congenital cases and discuss the complexity of managing congenital trismus due to brainstem dysgenesis in a neonate and infant.<\/jats:p>","DOI":"10.1542\/peds.2015-4605","type":"journal-article","created":{"date-parts":[[2016,6,3]],"date-time":"2016-06-03T09:07:25Z","timestamp":1464944845000},"source":"Crossref","is-referenced-by-count":2,"title":["Congenital Trismus From Brainstem Dysgenesis: Case Report and Review of Literature"],"prefix":"10.1542","volume":"138","author":[{"given":"Chris J.","family":"Hong","sequence":"first","affiliation":[{"name":"Faculty of Medicine, University of Ottawa, Ottawa, Ontario, Canada;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lisa","family":"Caulley","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, University of Ottawa, Ottawa, Ontario, Canada;"},{"name":"Department of Otolaryngology-Head and Neck Surgery, University of Ottawa, The Ottawa Hospital, Ottawa, Ontario, Canada; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Scott","family":"Kohlert","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, University of Ottawa, Ottawa, Ontario, Canada;"},{"name":"Department of Otolaryngology-Head and Neck Surgery, University of Ottawa, The Ottawa Hospital, Ottawa, Ontario, Canada; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gail E.","family":"Graham","sequence":"additional","affiliation":[{"name":"Departments of Genetics,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hugh J.","family":"McMillan","sequence":"additional","affiliation":[{"name":"Neurology,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jean","family":"Michaud","sequence":"additional","affiliation":[{"name":"Pathology and Laboratory Medicine, and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jean-Philippe","family":"Vaccani","sequence":"additional","affiliation":[{"name":"Otolaryngology-Head and Neck Surgery, University of Ottawa, Children\u2019s Hospital of Eastern Ontario, Ottawa, Ontario, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"417","published-online":{"date-parts":[[2016,7,1]]},"reference":[{"issue":"2","key":"2021120904542016400_B1","doi-asserted-by":"crossref","first-page":"88","DOI":"10.12968\/denu.2002.29.2.88","article-title":"Trismus: aetiology, differential diagnosis and treatment.","volume":"29","author":"Dhanrajani","year":"2002","journal-title":"Dent Update"},{"issue":"2","key":"2021120904542016400_B2","doi-asserted-by":"crossref","first-page":"123","DOI":"10.3109\/00016356009003005","article-title":"\u2018Elipsio prearticularis\u2019 of the temporomandibular joint.
