Twenty-six cases of mandibular fractures and luxations are reviewed. Mandibular trauma was due to car accidents (46%) and falls from great heights (23%). Cardiovascular shocks (40%), thoracic injuries (23%), epistaxis (30%), cleft palates (19%), subconjunctival hemorrhages (15%), broken canines (15%), concussions (15%), maxillary fractures (12%) were the most frequently encountered associated problems. Of the 26 cats, 22 had symphyseal fractures, 6 mandibular body fractures, 4 ramus fractures (3 of which were articular) and 6 had temporo-mandibular luxations. Open reduction and internal fixation was performed in 21 cases, surgery being indicated for unstable symphyseal and body fractures, the rostral body fractures being the most challenging to repair. Conservative therapy and ancillary treatment methods such as external coaptation and pharyngostomy were used for the fractures of the ramus. Six temporo-mandibular luxations associated with mandibular fractures in 5 cases were reduced under anesthesia. Good dental occlusion and mandibular function was obtained in the 24 treated cases.
回顾了26例下颌骨骨折和脱位病例。下颌骨创伤原因包括车祸(46%)和高处坠落(23%)。最常遇到的相关问题有心血管休克(40%)、胸部损伤(23%)、鼻出血(30%)、腭裂(19%)、结膜下出血(15%)、犬齿折断(15%)、脑震荡(15%)、上颌骨骨折(12%)。26只猫中,22例为正中联合骨折,6例为下颌骨体骨折,4例为下颌支骨折(其中3例为关节部骨折),6例为颞下颌关节脱位。21例进行了切开复位内固定,手术适用于不稳定的正中联合和下颌骨体骨折,修复最具挑战性的是下颌骨体前部骨折。下颌支骨折采用保守治疗及辅助治疗方法,如外固定和咽造口术。5例中6例与下颌骨骨折相关的颞下颌关节脱位在麻醉下进行了复位。24例接受治疗的病例获得了良好的牙合关系和下颌功能。
