Evaluation and Comparison of the Maxillary Palatal Volume of the Unilateral Cleft Lip and Palate Cases Treated with and without Presurgical Naso-Alveolar Molding as Compared to the Non-Cleft Children – A 3D DVT Study

BACKGROUND Cleft individuals have a significant altered growth of the craniofacial structures since birth. The treatments available for infants are mostly associated with controversies regarding timing of initiation, types & timing in surgery, grafting etc. Maxilla is affected in all three dimensions; due to surgery alone or in conjugation with the infant orthopaedics, intrinsic growth retardation or combination of all. Considering the current conflict over the use of pre-surgical nasoalveolar molding (PNAM) and to evaluate the efficacy of PNAM technique, this postdoctoral research was done to compare the maxillary palatal volume in unilateral cleft lip and palate (UCLP) cases treated with and without PNAM as compared to non-cleft individuals. METHODS This is an observational cross-sectional study. The palate alveolar volume was assessed and analysed using 3D-DVT angiography machine. RESULTS There was significant difference between cleft group and non-cleft individuals. The cases treated with PNAM had lesser palatal volume. CONCLUSIONS Restrictive effect on maxilla was evident in PNAM cases, but this altered growth could also be an amalgamation of numerous factors like surgery, infant orthopaedics, and intrinsic growth. Therefore, judicious use, current concepts, and biomechanics of PNAM is the need of an hour. KEY WORDS Maxillary Palatal Volume, Unilateral Cleft Cases, Presurgical Naso-Alveolar Molding, 3D-DVT
