The hypoplastic lateral lip element within the cleft lip presentation is a recognized entity that has been recently shown to be more common on the right side. The spectrum of such change is yet to be defined. The authors propose the Melbourne classification system of cleft lip hypoplasia and see it as an important step towards discerning the relevance of these anatomical observations to the management of cleft lip/palate patients.
This is a retrospective observational study of patients with complete unilateral cleft lips treated by the senior author (DKC) at the Royal Children's Hospital, Melbourne. Patient charts were retrospectively reviewed and patients were classified into different degrees of hypoplasia based on preoperative, intraoperative, and postoperative photography. Data was reported using descriptive statistics.
Fifty-nine patients with complete unilateral cleft lip deformity were grouped according to lateral lip element hypoplasticity. Twenty patients had right-sided clefts and 39 patients had cleft lips on the left side. Of those with right-sided clefts, 18 patients had evidence of hypoplasia (90%). Three patients had Type 1 deformities, 3 patients were Type 2, and 12 patients were Type 3. Patients with left-sided clefts were found to have hypoplasia less frequently with 15 patients showing evidence (38.5%).
The authors report a classification system of hypoplasia involving the lateral lip element in complete unilateral cleft lip. The authors propose this classification system as a new measure of cleft severity that will have implications for patient expectations, surgical planning, and future outcome studies.
裂隙唇表现中发育不良的侧唇元素是一种公认的实体，最近已被证明在右侧更为常见。这种变化的范围尚未确定。作者提出了墨尔本裂唇发育不良分类系统，并认为这是朝着辨别这些解剖学观察与裂唇/腭裂患者管理的相关性迈出的重要一步。
这是一项对由墨尔本皇家儿童医院的资深作者（DKC）治疗的完全单侧唇裂患者的回顾性观察性研究。回顾性地审查了患者的图表，并根据术前、术中、术后摄影将患者分为不同程度的发育不良。使用描述性统计数据报告数据。
根据侧唇元素发育不良，59 名完全单侧唇裂畸形患者被分为不同组。20 名患者有右侧裂隙，39 名患者有左侧裂隙。在右侧裂隙的患者中，18 名患者有发育不良的证据（90%）。3 名患者为 1 型畸形，3 名患者为 2 型，12 名患者为 3 型。左侧裂隙的患者发育不良的证据较少，有 15 名患者有证据（38.5%）。
作者报告了一个涉及完全单侧唇裂中侧唇元素发育不良的分类系统。作者提出了这个分类系统，作为裂唇严重程度的一个新指标，这将对患者的期望、手术计划和未来的结果研究产生影响。
