The purpose of the present review was to evaluate the protocol and technique used in a large population of patients with cleft lip and palate when secondary grafting is performed during the early mixed dentition stage, as determined by eruption of the central incisor. In the United States, most investigators have recommended alveolar grafting at the 9- to 11-year age range or before eruption of the permanent canines.
An institutional review board-approved chart review of 99 patients undergoing alveolar cleft bone grafting during a 7-year period at a single institution was performed. Data were collected regarding demographics, operative time, length of hospitalization, follow-up time, complications, and additional procedures performed. The cases were divided by patient age into 2 groups: group 1, aged 6 to 8 years (n = 61); and group 2, aged 9 years and older (n = 38). Statistical analysis was performed for various comparisons in the study.
The average operative time for groups 1 and 2 was 86 and 103 minutes, respectively. The complication rate, length of stay, and follow-up time between the 2 groups was not statistically significant at the P = .05 significance level.
We recommend earlier bone grafting at or before the eruption of the central incisor, rather than delaying until the cuspid tooth root is 25% formed. We believe this will provide better bone support for the dentition, a decreased burden of treatment for the patient, and improved quality of life. Performing the procedure at this time can lead to decreased operative times, with comparable postoperative outcomes.
本综述的目的是评估在乳牙混合早期(由中切牙萌出确定)对大量唇腭裂患者进行二次植骨时所采用的方案和技术。在美国,大多数研究者建议在9至11岁年龄范围或恒牙尖牙萌出之前进行牙槽突植骨。
对一家机构在7年期间接受牙槽突裂植骨的99例患者进行了经机构审查委员会批准的图表回顾。收集了有关人口统计学、手术时间、住院时间、随访时间、并发症以及所进行的其他手术的资料。将病例按患者年龄分为2组:第1组,年龄6至8岁(n = 61);第2组,年龄9岁及以上(n = 38)。对研究中的各种比较进行了统计分析。
第1组和第2组的平均手术时间分别为86分钟和103分钟。两组之间的并发症发生率、住院时间和随访时间在P = 0.05显著性水平上无统计学意义。
我们建议在中切牙萌出时或之前尽早进行植骨,而不是推迟到尖牙牙根形成25%时。我们认为这将为牙列提供更好的骨支持,减轻患者的治疗负担,并改善生活质量。此时进行该手术可缩短手术时间,术后结果相当。
