This report describes a 5-year-old Persian cat with recurrent right-sided jaw locking. Clinical examination revealed persistent open-mouth posture with mandibular deviation and mild symphyseal laxity. Computed tomography (CT) confirmed ventrolateral displacement of the right coronoid process, bilateral condylar subluxation, condylar flattening and elongation of the right retroarticular process. Due to recurrence, unilateral partial coronoidectomy was performed. Immediate and 8-week postoperative CT demonstrated restoration of mandibular alignment, improved TMJ congruity and resolution of impingement without recurrence. This case highlights the key role of CT in diagnosis, surgical planning, and follow-up of open mouth jaw locking in cats and supports surgical management in recurrent cases.<\/jats:p>","DOI":"10.1177\/08987564261459656","type":"journal-article","created":{"date-parts":[[2026,6,19]],"date-time":"2026-06-19T08:10:50Z","timestamp":1781856650000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Open-Mouth Jaw Locking in a Cat: Computed Tomography Diagnosis and Surgical Management \u2013 A Case Report"],"prefix":"10.1177","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-4458-8665","authenticated-orcid":false,"given":"Alejandro","family":"Blanco","sequence":"first","affiliation":[{"name":"Department of Animal Pathology, Faculty of Veterinary Science, University of Zaragoza, Zaragoza, Spain"},{"name":"Hospital de Urgencias Veterinarias de la Regi\u00f3n de Murcia, Murcia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fidel San","family":"Rom\u00e1n-Llorens","sequence":"additional","affiliation":[{"name":"Department of Animal Pathology, Faculty of Veterinary Science, University of Zaragoza, Zaragoza, Spain"},{"name":"Hospital Centro Cl\u00ednico Veterinario de Zaragoza, Zaragoza, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fidel San","family":"Rom\u00e1n","sequence":"additional","affiliation":[{"name":"Department of Animal Medicine and Surgery, Faculty of Veterinary Science, Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cristina","family":"Gonz\u00e1lez","sequence":"additional","affiliation":[{"name":"Department of Animal Pathology, Faculty of Veterinary Science, University of Zaragoza, Zaragoza, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alberto","family":"Climent","sequence":"additional","affiliation":[{"name":"Department of Animal Pathology, Faculty of Veterinary Science, University of Zaragoza, Zaragoza, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julia","family":"Laliena","sequence":"additional","affiliation":[{"name":"Department of Animal Pathology, Faculty of Veterinary Science, University of Zaragoza, Zaragoza, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manuel","family":"Alam\u00e1n","sequence":"additional","affiliation":[{"name":"Department of Animal Pathology, Faculty of Veterinary Science, University of Zaragoza, Zaragoza, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ana","family":"Whyte","sequence":"additional","affiliation":[{"name":"Department of Animal Pathology, Faculty of Veterinary Science, University of Zaragoza, Zaragoza, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,6,19]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.2460\/javma.1987.190.12.1574"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1177\/089875649200900102"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1177\/1098612X17737433"},{"key":"e_1_3_3_5_2","first-page":"144","volume-title":"Cirug\u00eda oral y maxilofacial del perro y el gato","author":"San Rom\u00e1n Ascaso F","year":"2020","unstructured":"San Rom\u00e1n Ascaso F, Whyte A, Trobo I.
