Objective To investigate whether timing of hard palate repair, before versus after pubertal peak velocity age, had a significant effect on facial growth in patients with unilateral cleft lip and palate. Design Retrospective cross-sectional study. Setting Sri Lankan Cleft Lip and Palate Project. Patients A total of 125 adult patients with nonsyndromic unilateral cleft lip and palate were recruited and their last cephalometric radiographs were used. Main Outcome Measures Clinical notes were used to record surgical treatment histories. Cephalometry was used to determine facial morphology. Results The patients who had hard palate repair after pubertal peak velocity age had a deeper bony pharynx (Ba-PMP), a longer alveolar maxilla (PMP-A), a longer effective length of the maxilla (Ar-ANS, Ar-A), and as a result had a more favorable anteroposterior jaw relation (ANS-N-Pog, ANB, NAPog) and larger overjet, compared with those who had hard palate repair before pubertal peak velocity age. Conclusion Timing of hard palate repair significantly affects the growth of the maxilla in patients with unilateral cleft lip and palate. Hard palate repair after (versus before) pubertal peak velocity age has a smaller adverse effect on the forward growth of the maxilla. This timing affects the forward displacement of the basal maxilla and the anteroposterior development of the maxillary dentoalveolus.

Objective: To investigate whether timing of hard palate repair had a significant effect on facial growth in patients with unilateral cleft lip and palate (UCLP). Design: Retrospective longitudinal study. Setting: Sri Lankan Cleft Lip and Palate Project. Patients: A total of 104 patients with nonsyndromic UCLP who had hard palate repair by age 13 years, with their 290 cephalometric radiographs taken after lip and palate repair. Main Outcome Measures: Clinical notes were used to record surgical treatment histories. Cephalometry was used to determine facial morphology and growth rate. Results: Timing of hard palate repair had a significant effect on the length and protrusion of the alveolar maxilla (PMP-A and SNA, respectively) and the anteroposterior alveolar jaw relation (ANB) at age 20 years but not on their growth rates. Conclusion: Timing of hard palate repair significantly affects the growth of the maxilla in patients with UCLP. Late hard palate repair has a smaller adverse effect than does early hard palate repair on the growth of the maxilla. This timing effect primarily affects the anteroposterior development of the maxillary dentoalveolus and is attributed to the development being undisturbed before closure of the hard palate.

Velopharyngeal Function

Aim: To examine the association of cleft severity at infancy and velopharyngeal competence in preschool children with unilateral cleft lip and palate operated with early or delayed hard palate repair. Design: Subgroup analysis within a multicenter randomized controlled trial of primary surgery (Scandcleft). Setting: Tertiary health care. One surgical center. Patients and Methods: One hundred twenty-five infants received cheilo-rhinoplasty and soft palate repair at age 3 to 4 months and were randomized to hard palate closure at age 12 or 36 months. Cleft size and cleft morphology were measured 3 dimensionally on digital models, obtained by laser surface scanning of preoperative plaster models (mean age: 1.8 months). Main outcome measurements: Velopharyngeal competence (VPC) and hypernasality assessed from a naming test (VPC-Sum) and connected speech (VPC-Rate). In both scales, higher scores indicated a more severe velopharyngeal insufficiency. Results: No difference between surgical groups was shown. A low positive correlation was found between posterior cleft width and VPC-Rate (Spearman = .23; P = .025). The role of the covariate “cleft size at tuberosity level” was confirmed in an ordinal logistic regression model (odds ratio [OR] = 1.17; 95% confidence interval [CI]:1.01-1.35). A low negative correlation was shown between anteroposterior palatal length and VPC-Sum (Spearman = −.27; P = .004) and confirmed by the pooled scores VPC-Pooled (OR = 0.82; 95% CI: 0.69-0.98) and VPC-Dichotomic (OR = 0.82; 95% CI: 0.68-0.99). Conclusions: Posterior cleft dimensions can be a modest indicator for the prognosis of velopharyngeal function at age 5 years, when the soft palate is closed first, independently on the timing of hard palate repair. Antero-posterior palatal length seems to protect from velopharyngeal insufficiency and hypernasality. However, the association found was significant but low.

Objective To compare growth, speech, and nasal symmetry outcomes of three methods of hard palate repair. Patients Consecutive available records of children born with unilateral bony complete cleft lip and palate over the period 1972 to 1992. Interventions Identical management of lip, nose, alveolus, and soft palate. Hard palate repair by Cuthbert Veau (CV) from 1972 to 1981, von Langenbeck (vL) from 1982 to 1989, or medial Langenbeck (ML) from 1989 to 1991. Outcome Measures For growth: GOSLON yardstick or 5-year model index. For speech: articulation test. Nasal anemometry. For nasal symmetry: Coghlan computer-based assessment. All these measures were developed during the period of data collection but not for this project. Results There was a strong trend toward more favorable anteroposterior maxillary growth with the change from CV to vL to ML techniques. This fell short of statistical significance because of the small sample size. There was a significant reduction in cleft-related articulation faults (p = .01) considered to be related to improved arch form. In the absence of improved rates of velopharyngeal insufficiency or nasal symmetry, increased surgical experience was discounted as a significant contribution to improved growth and articulation outcomes. Conclusions Reduced periosteal undermining and residual exposed palatal shelf from CV to vL to ML improved incisor relationships and articulation.

Objective: To evaluate the effect of timing of hard palate repair on facial growth in patients with cleft lip and palate, with special reference to cranial base, maxilla, mandible, jaw relation, and incisor relation. Design: A systematic review. Methods: The search strategy was based on the key words “facial growth,” “cleft lip palate,” and “timing of (hard) palate repair.” Case reports, case-series, and studies with no control or comparison group in the sample were excluded. Results: Fifteen studies met the selection criteria. All the studies were retrospective and nonrandomized. Five studies used cephalometry and casts, seven used cephalometry, and three used casts. Methodological deficiencies and heterogeneity of the studies prevented major conclusions. Conclusion: The review highlights the importance of further research. Prospective well-designed, controlled studies, especially targeting long-term results, are required to elucidate the effect of timing of hard palate repair on facial growth in patients with cleft lip and palate.
