The relationship between the type and side of the cleft and the left-right-handedness of the patient was evaluated in 706 patients with cleft, of whom 348 had unilateral cleft of the primary palate. The prevalence of left-handed persons in the group with left-sided cleft (14.5%) was more than three times as high as in the group with right-sided cleft (4.7%), a statistically significant difference. Among the 75 (10.6%) left-handed patients there were 38 unilateral clefts, of which 32 (84.2%) were on the left side; only 6 (15.8%) were on the right. Among the 631 right-handed patients there were 310 unilateral clefts, of which 122 (39.4%) were on the right and 188 (60.6%) were on the left side. Thus, the side of the cleft seemed to be associated with ipsilateral handedness. A large majority of left-handed patients have left-sided clefts, while right-handed patients are more heterogeneous in this respect.
在706例腭裂患者中评估了腭裂类型、侧别与患者左右利手之间的关系，其中348例为原发性腭裂单侧裂。左侧腭裂组中左利手者的患病率（14.5%）是右侧腭裂组（4.7%）的三倍多，差异有统计学意义。在75例（10.6%）左利手患者中有38例单侧腭裂，其中32例（84.2%）在左侧；仅6例（15.8%）在右侧。在631例右利手患者中有310例单侧腭裂，其中122例（39.4%）在右侧，188例（60.6%）在左侧。因此，腭裂侧别似乎与同侧利手相关。绝大多数左利手患者有左侧腭裂，而右利手患者在这方面则更为多样。
