Résumé
The complete cleft lip and palate children, ranging from 6-14 years of age were studied to evaluate the effect of variation in the timing of palatal repair on craniofacial morphology and compared to the noncleft children. It was observed that all the groups early (8 to < or = 24 months), medium (> 24 to < or = 36 months) and late repair (> 36 to < or = 78 months) had significantly larger cranial base, retruded maxillomandibular relations, skeletodental and incisal relationships compared to the noncleft children. However, intercomparison among the cleft groups showed insignificant difference amongst them suggesting that the timing of palatal repairs does not effect the anterioposterior (sagittal) relationship.

Nasality is related to factors like velopharyngeal closure and acoustic factors pertaining to cavities. The present investigation is a retrospective study aimed at evaluating the effects of variation in the timing of palatal repair on nasality during speech development in complete cleft lip and palate cases. It has been observed that the delay in palatal repair is associated with increase in nasality. Also, from the operated complete cleft lip and palate cases, it has been observed that the early and medium repair groups had almost similar effects on nasality of speech. (if they were operated before 36 months of age).

Fifty repaired complete cleft lip and palate cases (38 UCLP and 12 BCLP) in the age of 6 to 14 years were evaluated for sagittal craniofacial morphology using lateral cephalograms. A total of twenty three measurements (19 angular and 4 linear) were used in the analysis to represent a comprehensive pattern of dento craniofacial morphology. The results of comparison between UCLP and BCLP revealed differences for only the skeletodental and interincisor sagittal relationship (greater retroclination in BCLP group).

Forty cleft cases in the age range of 5-12 years where the palatal repair had been performed at 16-24 months (17 cases), 24-36 months (15 cases) and 36-72 months (8 cases) were assessed retrospectively, for the status of maxillary arch and were segregated as acceptable and unacceptable. Plaster casts were prepared from alginate impressions and their graphical reproduction using Huddart's technique, were used to measure the alveolar arch. Anterior palatal measurement (C-C') and posterior palatal measurement (P-P') of the cleft subjects were compared with that in the non-cleft matched controls. The 16-24 month group showed 41.2% acceptable and 58.8% unacceptable arch cases. The 24-36 month group showed that 73.4% had acceptable arches and 26.6% had unacceptable arches. In the 36-72 months group the arch was acceptable in 62.5% cases and unacceptable in 37.5% cases. It was concluded that palatal repair performed before 24 months of age adversely affected the maxillary growth, whereas most favourable growth of maxillary arch occurred when the repair was done between 24-36 months.

Fifty repaired complete cleft lip and palate cases (38 UCLP and 12 BCLP) in the age range of 6 to 14 years were evaluated for transverse and vertical asymmetry using postero-anterior cephalograms. A total of nine bilateral landmarks, representing upper face, mid face and lower face were used. Results showed that asymmetry was not confined to any single plane of reference but manifested in both dimensions--transverse and vertical. The UCLP group had greater asymmetry of mid face than the BCLP group. Asymmetry was found to be extending to distant areas besides the contiguous structures.
