Shallow upper buccal sulcus deformity in cleft lip and palate patients is one of the common secondary deformities after primary cleft lip and palate repair; this deformity may prevent or complicate orthodontic and prosthodontic procedures causing aesthetic and functional problems. A number of methods are described to increase the anterior maxillary sulcus in these patients.
This study assessed the use of a carbon dioxide laser (CO) to increase the sulcus depth.
Fifteen patients with cleft lip and palate (eight unilateral and seven bilateral) were studied. The surgical procedure was performed using CO laser. The vestibular depth and lip length were measured at three time points namely before surgery (T0), 1 week following surgery (T1), and 4 months following surgery (T2). After data collection, statistical analyses were done using PASW version 18 SPSS.
The mean values of vestibular depth were 9.46 ± 1.92, 13.83 ± 1.88, and 13.23 ± 1.76 mm for T0, T1, and T2, respectively. The vestibular depth significantly increased after 4 months of follow-up (p = 0.001). The mean amount of vestibular depth gain was not significantly different in unilateral and bilateral cleft groups (p = 0.908). The mean value of upper lip length increased by a mean of 1.23 mm and was statistically significant (p = 0.001).
Upper buccal sulcus reconstruction with CO laser provides successful and stable results. CO laser application is suggested as an alternative to conventional vestibuloplasty.
唇腭裂患者上颌颊侧浅沟畸形是唇腭裂一期修复术后常见的继发畸形之一；这种畸形可能会妨碍正畸和修复治疗，或使其复杂化，从而导致美观和功能问题。已有多种方法用于增加这些患者的上颌前部沟深。
本研究评估使用二氧化碳激光（CO₂）增加沟深的效果。
对15例唇腭裂患者（8例单侧，7例双侧）进行研究。采用CO₂激光实施手术。在三个时间点测量前庭深度和唇长，即术前（T0）、术后1周（T1）和术后4个月（T2）。收集数据后，使用PASW 18版SPSS进行统计分析。
T0、T1和T2时前庭深度的平均值分别为9.46 ± 1.92、13.83 ± 1.88和（此处原文有误，推测为13.23 ± 1.76）13.23 ± 1.76mm。随访4个月后前庭深度显著增加（p = 0.001）。单侧和双侧腭裂组前庭深度增加量的平均值无显著差异（p = 0.908）。上唇长度平均值增加了1.23mm，具有统计学意义（p = 0.001）。
用CO₂激光进行上颌颊沟重建可取得成功且稳定的效果。建议将CO₂激光应用作为传统前庭成形术的替代方法。
