“…Different handling protocols are needed, where surgical maxillary advancement via orthodontic functional devices, orthognathic surgery, or distraction osteogenesis are required in case of rudimentary hypoplastic premaxilla,[11] whereas in case of protruding premaxilla, presurgical orthopedics is usually required.

Aim:The aim of this study was to compare the number of teeth in the premaxilla (cleft area) and to assess the presence of tooth agenesis with the ultimate goal of finding whether differences existed in the two suggested subtypes of nonsyndromic bilateral cleft lip and palate (BCLP) patients.Settings and Design:A retrospective comparative study was conducted, where cone- beam computed tomography (CBCT) images of 22 BCLP patients (10 males and 12 females, with age range 8 to 14, mean age 9.6 years) obtained from archive of Cleft Clinic, affiliated to the Oral and Maxillofacial Surgery department, Ain-Shams University, Cairo, Egypt were assessed.Subjects and Methods:CBCT images were divided into two subtypes: Group (P) – this represents BCLP characterized by well-developed (P) prominent premaxilla and SNA >80 ± 2 and Group (R) – this represents BCLP characterized by ill-developed (R) rudimentary premaxilla and SNA <80 ± 2. The number of teeth in the premaxilla was evaluated, and the presence of agenesis in the premaxilla and posterior segments was documented.Statistical Analysis Used:Unpaired-Student's t-test was used to compare the number of teeth among the two groups and to test significance at P < 0.05. Intraobserver agreement was assessed using alpha (Cronbach) reliability analysis. A descriptive analysis using percentages was performed to characterize tooth agenesis.Results:A significant difference was found in the number of teeth in the premaxilla among Group R and Group P. Maxillary lateral incisor showed the highest percentage of agenesis in the two groups followed by the maxillary second premolar.Conclusions:The number of teeth might be useful in differentiating different subtypes of nonsyndromic BCLP.

“…These variations may affect results of treatment and necessitate modifications in treatment planning. Different handling protocols may be needed for the patients with different subtypes of BCLP, where Surgical maxillary advancement via orthodontic functional devices, orthognathic surgery or distraction osteogenesis are required in case of rudimentary hypoplastic premaxilla (36) , while in case of protruding premaxilla, presurgical orthopedics, orthodontics or surgical repositioning of the premaxilla might be required (11).…”

Objective: The purpose of this study was to investigate maxillofacial morphology using CBCT with the ultimate goal of finding whether differences existed in a two suggested subtypes of nonsyndromic bilateral cleft lip and palate (BCLP) patients.Design: This retrospective study included CBCT data of 22 BCLP patients with mean age of 9.6 years. The patients were divided initially according to premaxillary characteristics into two groups and this classification was further confirmed by measurement of sella-nasion-point A angle (SNA), Group (P): This represent BCLP characterized by well-developed (P) prominent pre-maxilla and SNA >80±2, Group(R): This represent BCLP characterized by ill-developed (R) rudimentary pre-maxilla and SNA < 80±2. The relation between maxilla and mandible measured by point A-nasion-B point angle (ANB), angle of septal deviation (ASD) and anterior upper facial height (AUFH) were assessed using On-demand 3D software and was compared among the two groups.Results: Patients within group P showed significantly higher ANB (P value ≤ 0.001). Patients within group R showed significantly higher ASD angle (P value ≤ 0.05), while AUFH showed insignificant difference between the two groups (P value ≥ 0.05). Conclusions:Maxillofacial morphology measurements assessed in this study support that difference exist between the two investigated subtypes of non-syndromic BCLP.

Objective: To evaluate the long-term effect of timing of 1-stage palatoplasty on midfacial growth in patients with cleft lip and palate (CLP). Design: Retrospective observational cohort study. Study Setting: Institutional hospital. Patients: One hundred twelve patients with CLP who underwent palatoplasty and were divided into 3 groups: group I: operated between 9 and 11 months; group II: operated between 18 and 20 months; and group III: operated between 21 and 24 months. Interventions: All patients underwent von Langenbeck palatoplasty technique, which was converted to a Bardach 2-flap technique in case of any technical difficulties. The patients were followed up between 8 and 9 years when they reported for secondary alveolar bone grafting. Postsurgical cephalometric and dental casts measurements were taken for midfacial growth analysis. Main Outcome Measures: The cephalometric measures were analyzed for midfacial growth and compared within the groups. Results: Statistically significant difference ( P < .01) was found on comparing the cephalometric parameters such as sella–nasion–A point angle (SNA), A point–nasion–B point angle (ANB), n toperpendicular to point A (N-perpA), condylon to point A (Co-A), anterior nasal spine to posterior nasal spine (ANS-PNS), nasion to Anterior nasal spine (N-ANS), nasion to menton (N Me), and witts appraisal (Witt (AO-BO)) in group I when compared to both group II and group III patients, implying deficient midfacial growth in group I. No statistical difference was found in the cephalometric values between group II and group III. Group II had better cephalometric measurements than group III, showing better growth in group II than group III. Overall, there was less incidence of midfacial hypoplasia in patients treated between 18 and 20 months (group II). Conclusion: We conclude that palatal closure carried out at 18 to 20 months and 21 to 24 months is associated with better midfacial growth when compared to closure at 9 to 11 months. The best time to operate would be between 18 and 20 months to avoid speech disturbances. Midfacial growth can be greatly influenced by the timing of 1-stage palatoplasty.
