JOURNAL RESTRICTED ACCESSGingivoperiosteoplasty (GPP) is a surgical technique to create a periosteal flap for bone bridge formation between the alveolar cleft in infants. In order to evaluate this point, the formation of the bone bridge and the development of permanent teeth were examined three-dimensionally in four cases with complete unilateral cleft lip and palate (UCLP) by cone beam CT (CBCT) taken from 5 to 7 years of age. After alveolar clefts were molded by presurgical infant orthopedics, Millard-type GPP together with Noordhoff-type of cheiloplasty, and intravelar veloplasty with Furlow palatoplasty were performed at 106-150 days old and 14-16 months old, respectively, by the same plastic surgeon. All four cases showed bone bridge formation between alveolar clefts. The vertical height of the bone bridge was 5.7-11.6 mm, which corresponded to 29.8-56.9% of the vertical distance between the inferior border of the piriform aperture in the cleft sides and the inferior border of alveolar bone in the non-cleft sides. The average maximum labio-lingual width of the bone bridge in four cases was 4.5-6.7 mm. The inferior border of the bone bridge was located near the inferior border of the piriform aperture in two cases and near the alveolar bone bridge in the other two cases. Two permanent lateral incisors were congenitally missing adjacent to the alveolar cleft.View full abstractDownload PDF (1287K) -

JOURNAL RESTRICTED ACCESSObjective: The postoperative evaluation of bone formation in the alveolar cleft by computed tomography imaging is reported. We quantitatively evaluated bone grafts in the alveolar cleft preoperatively and postoperatively using three-dimensional data and superimposition of images.
Subjects: A total of 12 patients with complete unilateral cleft lip and palate (six left-sided and six right-sided) were studied.
Methods: Helical computed tomography scans were taken immediately before surgery and at 6 months after surgery and the DICOM files obtained were processed using Mimics and 3-matic software for three-dimensional data analysis. The preoperative and postoperative computed tomography data were superimposed, and the position and length of the unerupted canines and width of the alveolar cleft were measured.
Results: Strong and significant correlations were observed between bone formation in the alveolar cleft bone graft region and preoperative canine position (r = -0.766, p < 0.01) and canine length (r = 0.681, p < 0.05). Stepwise multiple regression analysis demonstrated that only the preoperative canine position was independently and significantly correlated with bone formation in the alveolar cleft.
Conclusion: These results indicate that the optimal timing for surgery is when the canine cusp is close to the alveolar plane.View full abstractDownload PDF (611K)

JOURNAL RESTRICTED ACCESSA statistical investigation was carried out on patients with cleft lip and/or palate in the Department of Oral and Maxillofacial Surgery, Kyushu University Hospital during the 10-year period from January 1998 to December 2007. The results were as follows:
1. The total number of primary cases was 228 (males, 102; females, 126).
2. There were 70 patients with cleft lip and palate, 70 patients with cleft lip (and alveolar), 69 patients with cleft palate, 18 patients with submucous cleft palate and 1 patient with facial cleft.
3. Cleft lip and palate was more frequent in males, and cleft palate was more frequent in females.
4. Ninety percent of patients visited within 1 month of age.
5. Most of the patients were residents of Fukuoka city or the surrounding area.
6. The largest majority of patients were referred from other obstetric clinics other than the obstetric department of Kyushu University Hospital.
7. The total number of prenatal counseling cases was 18, and the number of cases of postnatal rounds in obstetric clinics was 63. The number of both prenatal counseling case and postnatal round cases gradually increased.View full abstractDownload PDF (1054K)
