Early Alveolar Bone Grafting Is Associated with Lower Regraft Rates and Improvements in Long-Term Psychosocial Outcomes.

BACKGROUND: Late childhood (8 to 10 years of age) has emerged as a vulnerable period in children with cleft and craniofacial anomalies such that increased interventions during this period are associated with worse long-term patient-reported anxiety and depressive symptoms. These findings suggest that one possible practice change may be to consider changes in timing for surgical treatment algorithms. In this work, the authors investigated outcomes in altering the timing of the most common operation in late childhood for cleft lip and palate patients, alveolar bone grafting. METHODS: A two-part, multi-institutional cohort study was conducted. To understand the feasibility of changing alveolar bone graft timing with respect to surgical success, reoperation rates were retrospectively compared among patients grafted at different ages (4 to 7, 8 to 10, and 11 to 13 years of age). To understand the long-term effect of changing alveolar bone graft timing on psychosocial outcomes, the psychosocial suite of the Patient-Reported Outcomes Measurement Information System was prospectively administered to teenagers and adults with cleft lip and palate. RESULTS: Among the three age groups, early grafting (4 to 7 years of age) demonstrated the lowest regraft rates compared with the other groups. As these results suggested that early grafting is a viable alternative to standard timing, we next compared the differences in long-term psychosocial outcomes. Patients who were grafted early reported lower levels of anxiety and depressive symptoms as teenagers and adults. CONCLUSION: Altering timing of one stage in cleft lip and palate reconstruction to an earlier age decreases regraft rates and improves long-term patient-reported anxiety and depressive symptoms.

Study on Tooth Movement After the Alveolar Bone Grafting in Patients With Unilateral Cleft Lip and Palate.

OBJECTIVES: The aim of the study was to explore the effectiveness of the cleft-adjacent teeth moved into the grafted alveolar bone in unilateral cleft lip and palate (UCLP) patients, and to evaluate the alveolar bone support of the teeth. METHODS: Twenty unilateral cleft lip and palate patients were recruited in this study. The average age was 12 years and 8 months. Periapical radiographs were taken for the cleft-adjacent teeth 3 months after bone grafting (T1) and after teeth moving into the grafted bone (T2), and for the contralateral teeth (T3) when teeth aligned. Alveolar bone support of the moved teeth and the contralateral teeth were measured using the ratio of bone support height to root length. Paired t test was performed for statistical analysis with SPSS17.0 software package. RESULTS: All the cleft-adjacent teeth were bodily moved into the grafted area. Average alveolar bone support ratio for the moved teeth was 86.48% (T1), 87.11% (T2), and 90.81% (T3) for the contralateral teeth. There was no statistically significant difference between T1 and T2 (P > 0.05). Although the contralateral teeth had the highest alveolar bone support ratio, significant differences were found between T3 and T2 (P < 0.05). CONCLUSIONS: Cleft-adjacent teeth could be bodily moved into the grafted bone from the iliac crest in UCLP patients. A successful level of alveolar bone support for the moved teeth was achieved. Moved-in teeth could be functionally loaded and may be benefit to the reduction of the resorption of grafted bone.

Outcome of Patients with Complete Unilateral Cleft Lip and Palate: 20-Year Follow-Up of a Treatment Protocol.

BACKGROUND: The treatment plan for cleft lip and palate varies among centers and requires long-term evaluation of its final outcome. METHODS: A consecutive series of patients born from 1994 to 1996 were reviewed. Inclusion criteria were complete unilateral cleft lip and palate, undergoing all treatment procedures performed by the team, and continuous follow-ups until 20 years of age. Exclusion criteria were incomplete data, having microform cleft lip on the contralateral side, presence of the Simonart band, and other abnormalities. RESULTS: A total of 72 patients were included. Average age at final evaluation was 21.3 years; 83.3 percent of patients underwent one-stage rotation-advancement lip repair and 16.7 percent underwent two-stage repair with an initial adhesion cheiloplasty. All patients underwent palate repair using the two-flap method at an average age of 12.3 months. Velopharyngeal insufficiency occurred and required surgical interventions in 19.4 percent during the preschool age and in 16.7 percent at the time of alveolar bone grafting; 56.9 percent of patients underwent secondary lip/nose revision during the growing age. Regular orthodontic treatment was administered to 34.7 percent of patients between 12 and 16 years of age. Orthodontic treatment and orthognathic surgery were applied in 37.5 percent of the patients after maturity. The average number of surgical procedures to complete the treatment was 4.8 per patient. CONCLUSIONS: This treatment protocol provided generally acceptable final outcome after the 20-year follow-up. Some results were less ideal and have resulted in modifications of the planning and methods in the protocol. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Efficacy of Facilitated Capacity Building in Providing Cleft Lip and Palate Care in Low- and Middle-Income Countries.

Providing surgical repair for congenital anomalies such as cleft lip and palate (CLP) can be challenging in low- and middle-income countries. One nonprofit organization seeks to address this need through a partnership model. This model provides long-term aid on multiple levels: surgeon and healthcare provider education, community outreach, and funding. The authors examined the effectiveness of this partnership model in providing CLP care and increasing cleft care capacity over time. This organization maintains data on each partner and procedure and collected data on hospital and patient characteristics through voluntary partner surveys from 2010 to 2014. Effectiveness of care provision outcomes included number of surgeries/partner hospital and patient demographics. Cleft surgical system strengthening was measured by the complexity of repair, waitlist length, and patient follow-up. From 2001 to 2014, the number of procedures/hospital/year grew from 15 to 109, and frequency of alveolar bone grafts increased from 1% to 3.4%. In addition, 97.9% of partners reported that half to most patients come from rural areas. Waitlists decreased, with 9.2% of partners reporting a waitlist of ≥50 in 2011 versus 2.7% in 2014 (P < 0.001). Patient follow-up also improved: 35% of partners in 2011 estimated a follow-up rate of ≥75%, compared with 51% of partners in 2014 (P < 0.001). The increased number of procedures/hospital/year supports the partnership model's effectiveness in providing CLP care. In addition, data supports cleft surgical system strengthening-more repairs use alveolar bone grafts, waitlists decreased, and follow-up improved. These findings demonstrate that the partnership model may be effective in providing cleft care and increasing cleft surgical capacity.

Accurate Evaluation of Cone-Beam Computed Tomography to Volumetrically Assess Bone Grafting in Alveolar Cleft Patients.

OBJECTIVE: The aim of this study was to investigate the accuracy of cone-beam computed tomography (CBCT) to assess the volume of bone graft in alveolar cleft patients. MATERIALS AND METHODS: Twelve patients of unilateral alveolar cleft were included in this study. All patients were taken CBCT preoperative and 1 week postoperative. The digital imaging and communications in medicine (DICOM) files were imported into Simplant software and three-dimensional (3D) reconstruction of the alveolar defect was achieved. With 3D volumetric measurements module, the volume of alveolar cleft was calculated preoperatively. During operation, the syringe compression method was adopted to calculate the actual amount of bone graft. One week postoperative, CBCT scan was performed again to measure the bone volume grafted to the defect. The volumetric ratio of the syringe compression method to preoperative CBCT assessment and the volume difference between syringe compression method and postoperative CBCT assessment were analyzed to evaluate the accuracy of CBCT measurement. RESULTS: The 3D structure of the alveolar cleft and the boundary of bone graft was clear from CBCT images. The estimated volume of alveolar cleft by preoperative CBCT scans was 1.06 ±â€Š0.09 cm, and the actual amount of bone graft determined by the syringe compression method was 1.51 ±â€Š0.12 cm. The ratio between the latter to the former was 1.43 ±â€Š0.07. The calculated volume of bone graft by 1-week postoperative CBCT scans was 1.53 ±â€Š0.11 cm, with no significant difference compared with the actual amount of bone graft (P > 0.05). CONCLUSIONS: CBCT was an accurate measurement to calculate the volume of alveolar defect and bone graft in alveolar cleft patients. Preoperative scans could aid in quantitatively determining the bone amount needed to adequately fill the bone defect, and the postoperative scans give accurate follow-up evaluation after surgery.
