End-stage masticatory muscle fibrosis may occur following trauma, resulting in the inability to open the mouth for eating, drinking, panting and vomiting. Following MRI and EMG confirmation of end-stage muscle fibrosis, a bilateral wedge ostectomy was performed of the mandibles, leaving a permanent mouth opening of 3.5 cm. The osteotomies were stabilized with 6-hole dynamic compression plates and screws. A temporary percutaneous endoscopic gastrotomy tube was placed while the dog underwent rehabilitation and reconditioning. The dog was able to eat, drink, and pant after recovery, which allowed the dog to live a relatively normal and good quality life. Wedge osteotomies of the mandibles with bone plate stabilization may allow dogs with permanent restrictive mouth opening due to fibrosis of the masticatory muscles to live a relatively normal life.
终末期咀嚼肌纤维化可能在创伤后发生，导致无法开口进食、饮水、喘气和呕吐。在通过MRI和肌电图确认终末期肌肉纤维化后，对下颌骨进行了双侧楔形截骨术，使口腔永久开口3.5厘米。截骨处用6孔动力加压钢板和螺钉固定。在犬康复和调养期间放置了临时经皮内镜胃造瘘管。犬恢复后能够进食、饮水和喘气，使其能够过上相对正常且质量良好的生活。下颌骨楔形截骨术并使用骨板固定，可能使因咀嚼肌纤维化而永久性张口受限的犬过上相对正常的生活。
