A survey was made of the upper cervical vertebrae in children with cleft lip and palate in order to determine the prevalence of cervical vertebral anomalies. The cleft sample consisted of 105 patients attending for orthodontic treatment. It was subdivided into cleft lip (CL), cleft palate (CP), unilateral cleft lip and palate (UCLP) and bilateral cleft lip and palate (BCLP) subgroups. A control was comprised of 120 orthodontic patients. The cervical vertebral anomalies were classified into two types, posterior arch deficiency (PAD) and fusion anomalies (FUS). The results confirmed that the cervical vertebral anomalies occurred significantly more often in the cleft sample (13%) than in the controls (0.8%), p less than 0.001. The total prevalence of cervical vertebral anomalies was similar in the four cleft sub-samples, but the occurrence of each of the two types of cervical vertebral anomalies showed a more differentiated pattern. Posterior arch deficiency occurred significantly more often in cleft palate (CP), (16%) than in controls p less than 0.001, but fusions did not occur more frequently in any cleft groups than in controls.
为了确定颈椎异常的患病率，对唇腭裂患儿的上颈椎进行了一项调查。腭裂样本包括105名接受正畸治疗的患者。它被细分为唇裂（CL）、腭裂（CP）、单侧唇腭裂（UCLP）和双侧唇腭裂（BCLP）亚组。对照组由120名正畸患者组成。颈椎异常分为两种类型，后弓缺如（PAD）和融合异常（FUS）。结果证实，腭裂样本中颈椎异常的发生率（13%）明显高于对照组（0.8%），p<0.001。四种腭裂亚样本中颈椎异常的总患病率相似，但两种类型的颈椎异常的发生呈现出更具差异的模式。后弓缺如在腭裂（CP）中的发生率（16%）明显高于对照组，p<0.001，但在任何腭裂组中融合异常的发生率都不比对照组高。
