BACKGROUND:Outcomes for a continuously applied alveolar bone grafting protocol, established in 1982, are reported and compared to previously published outcomes from the authors' unit and elsewhere. METHODS:A descriptive, retrospective cohort study of alveolar bone grafting outcomes at a tertiary referral cleft center was performed. Records of all alveolar bone grafts between 2002 and 2014 were reviewed (224 grafts). Three-year postoperative periapical radiographs were evaluated using the Bergland, Kindelan, and standardized way to assess graft scores by an external rater. Incomplete records, a syndromic diagnosis, or primary surgery performed elsewhere resulted in 123 grafts being excluded, leaving 101 grafts for assessment. The distribution of scores was compared to the authors' previous studies and international reports. The authors also tested for any impact on the outcome based on cleft type, laterality, timing for incisor or canine eruption, and surgeon experience. RESULTS:A total of 95.6 percent of applicable grafts (66 of 69) were considered "successful" by Bergland scores and 96 percent by Kindelan scores. Eighty-nine percent of grafts were "very good" based on standardized way to assess graft score. No significant differences were detected in outcomes based on timing, cleft type, or laterality. Surgeon experience had a significant impact (p < 0.05) on outcome for Bergland and Kindelan scores. Distribution of Bergland scores did not differ from the authors' earlier studies demonstrating consistent outcomes for over 30 years. CONCLUSIONS:The Western Australian alveolar bone grafting protocol has consistently achieved a very high success rate (96 percent) for over 30 years despite multiple staff changes. These results compared well with best-reported outcomes from worldwide cleft centers. Surgeon training and experience were significant in achieving these outcomes. CLINICAL QUESTION/LEVEL OF EVIDENCE:Therapeutic, IV.


背景: 报告了 1982 年建立的持续应用牙槽骨移植方案的结果,并与作者单位和其他地方以前发表的结果进行了比较。 方法: 进行了一项关于三级转诊腭裂中心牙槽骨植骨结局的描述性、回顾性队列研究。回顾了 2002 年至 2014 年间所有牙槽骨移植物的记录 (224 个移植物)。使用Bergland、Kindelan和标准化方法评估三年术后根尖周x线片,通过外部评定者评估移植物评分。记录不完整、综合征诊断或其他地方进行的初次手术导致 123 例移植物被排除,剩余 101 例移植物供评估。将评分分布与作者以前的研究和国际报告进行比较。作者还根据裂隙类型、偏侧性、切牙或尖牙萌出的时间以及外科医生的经验,测试了对结局的任何影响。 结果: 共有 95.6% 的适用移植物 (69 例中的 66 例) 被Bergland评分认为 “成功”,96% 被Kindelan评分认为 “成功”。根据评估移植物评分的标准化方法,89% 的移植物 “非常好”。未检测到基于时间、裂隙类型或偏侧性的结局存在显著差异。外科医生的经验对Bergland和Kindelan评分的结果有显著影响 (p <0.05)。Bergland评分的分布与作者早期的研究无差异,证明 30 多年来的结果一致。 结论: 西澳大利亚牙槽骨移植方案 30 多年来一直取得了非常高的成功率 (96%),尽管有多个工作人员的变化。这些结果与来自全球腭裂中心的最佳报告结果进行了良好的比较。外科医生的培训和经验对实现这些结果意义重大。 临床问题/证据水平: 治疗性,IV。

METHODS:BACKGROUND:The anterior oronasal fistulae neighboring the alveolar cleft could persist or reappear after the alveolar reconstruction with cancellous bone grafting. The persistent symptomatic anterior oronasal fistulae need to be repaired, but surgery remains a challenge in cleft care. Surprisingly, this issue has rarely been reported in the literature. The purpose of this long-term study was to report a single surgeon experience with a therapeutic protocol for persistent symptomatic anterior oronasal fistula repair. METHODS:This is a retrospective study of consecutive patients with Veau type III and IV clefts and persistent symptomatic anterior oronasal fistulae managed according to a therapeutic protocol from 1997 to 2018. Depending on fistula size, patients were treated with local flaps associated with an interpositional graft or two-stage tongue flaps (small/medium or large fistulae, respectively). The surgical outcomes were classified as "good" (complete fistula closure with no symptoms), "fair" (asymptomatic narrow fistula remained), or "poor" (failure with persistent symptoms). RESULTS:Forty-four patients with persistent symptomatic anterior oronasal fistulae were reconstructed with local flaps associated with interpositional fascia or dermal fat grafting (52.3%) or two-stage tongue flaps (47.7%). Most of patients (93.2%) presented "good" outcomes, ranging from 87% to 100% (local and tongue flaps, respectively). Three (6.8%) patients presented symptomatic residual fistula ("poor" outcomes). CONCLUSIONS:For the repair of persistent symptomatic anterior oronasal fistulae, this therapeutic protocol provided satisfactory outcome with low fistula recurrence rate.

METHODS:OBJECTIVE:Methadone is a vital treatment for women with opioid use disorder in pregnancy. Previous reports suggested an association between methadone exposure and Pierre Robin sequence (PRS), a rare craniofacial anomaly. We assessed the association between gestational methadone exposure and PRS. DESIGN/SETTING:This case-malformed control study used European Surveillance of Congenital Anomalies population-based registries in Ireland, the Netherlands, Italy, Switzerland, Croatia, Malta, Portugal, Germany, Wales, Norway and Spain, 1995-2011. PATIENTS:Cases included PRS based on International Classification of Disease (ICD), Ninth Edition-British Paediatric Association (BPA) code 75 603 or ICD, Tenth Edition-BPA code Q8708. Malformed controls were all non-PRS anomalies, excluding genetic conditions, among live births, fetal deaths from 20 weeks' gestation and terminations of pregnancy for fetal anomalies. An exploratory analysis assessed the association between methadone exposure and other congenital anomalies (CAs) excluding PRS. Methadone exposure was ascertained from medical records and maternal interview. RESULTS:Among 87 979 CA registrations, there were 127 methadone-exposed pregnancies and 336 PRS cases. There was an association between methadone exposure and PRS (OR adjusted for registry 12.3, 95% CI 5.7 to 26.8). In absolute terms, this association reflects a risk increase from approximately 1-12 cases per 10 000 births. A raised OR was found for cleft palate (adjusted OR 5.0, 95% CI 2.7 to 9.2). CONCLUSIONS:These findings suggest that gestational methadone exposure is associated with PRS. The association may be explained by unmeasured confounding factors. The small increased risk of PRS in itself does not alter the risk-benefit balance for gestational methadone use. The association with cleft palate, a more common CA, should be assessed with independent data.

METHODS::Orthopedic treatment to improve deficient maxillary growth of cleft lip and palate patients is an important part of treatment. The success of this treatment is strongly dependent on the time of initiation of therapy. There has been a large controversy in the available literature regarding the skeletal age of these patients. The aim of the present study was to compare the skeletal age of cleft lip and palate patients with normal individuals.37 unilateral and 14 bilateral cleft lip and palate patients and 47 healthy individuals participated in this cross-sectional study. The patients were classified into 8 to 10 and 11 to 14-year-old individuals. Cervical vertebral maturational stage of participants was evaluated in the lateral cephalometry. The skeletal age of cleft lip and palate patients was compared with normal controls. Chi-square was used for statistical analysis. There was not a significant difference in the skeletal developmental stage of unilateral and bilateral cleft compared to their normal peers according to their age and sex. Also, significant difference in skeletal maturational stage of cleft lip and palate patients was not found between boys and girls (P = 0.8). Similarly, no significant difference was found in the skeletal age of the 3 studied groups without considering the age and sex of participants (P = 0.5). Regarding the similar skeletal maturational stage of cleft lip and palate patients with normal controls in our study, their maxillofacial orthopedic treatment can be initiated at similar time to normal peers.
