To evaluate craniomaxillofacial abnormalities in dogs with congenital palatal defects.
Retrospective computed tomography (CT) study.
Dogs with congenital palatal defects (n = 9).
Medical records and CT reports (1995-2012) were searched for dogs with a diagnosis of cleft palate that had a CT study. Data retrieved were: breed, age, sex, weight, physical examination, and laboratory findings, number of previous palate surgeries, and oral/dental examination findings with the diagnosis of the cleft for each dog. CT studies of the head were reviewed on a structure-by-structure basis.
Tympanic bullae were most commonly found to be abnormal (8 dogs), followed by nasal turbinates (6), nasal septum, vomer, cribriform plate (4), frontal sinuses, and lateral ventricles (3). Other abnormalities were related to occlusion, teeth, incisive bones, maxillary bones, mandibles, hyoid apparatus, cranial bones, and nasopharynx. The soft tissue defect of the cleft was always smaller than the bony defect.
Craniomaxillofacial abnormalities in dogs with congenital palatal defects are common and some of these may negatively affect the quality of life. Importantly for surgical planning, the soft tissue component of the cleft may underestimate the extent of the bony defect, especially in failed repairs.
评估患有先天性腭裂的犬的颅颌面异常情况。
回顾性计算机断层扫描（CT）研究。
患有先天性腭裂的犬（n = 9）。
检索1995年至2012年期间诊断为腭裂且进行了CT检查的犬的病历和CT报告。检索到的数据包括：品种、年龄、性别、体重、体格检查和实验室检查结果、既往腭裂手术次数以及每只犬腭裂诊断的口腔/牙齿检查结果。对头部的CT研究进行逐结构审查。
最常发现鼓泡异常（8只犬），其次是鼻甲（6只）、鼻中隔、犁骨、筛板（4只）、额窦和侧脑室（3只）。其他异常与咬合、牙齿、切骨、上颌骨、下颌骨、舌骨装置、颅骨和鼻咽有关。腭裂的软组织缺损总是小于骨缺损。
患有先天性腭裂的犬的颅颌面异常很常见，其中一些可能对生活质量产生负面影响。对于手术规划而言重要的是，腭裂的软组织部分可能会低估骨缺损的程度，尤其是在修复失败的情况下。
