The impact of presurgical orthopedics appliances (PSOAs) in bilateral cleft patients.
Masters thesis, Universiti Sains Malaysia.
Abstract
Introduction: Acceptable maxillary growth in bilateral cleft lip and palate (BCLP) is
difficult to achieve. Presurgical orthopaedic treatment aims at reduction of cleft size by
guiding growth and functional rehabilitation. The objectives of this study were to
evaluate the impact of Presurgical Orthopaedic Appliances (PSOA) on facial growth in
BCLP.
Methods: Subjects were patients who were treated in Hospital Universiti Sains,
Malaysia, and Hospital Raja Perempuan Zainab II. Ages ranged 7 – 21 years of age
with nonsyndromic cleft and no associated anomalies. A lateral cephalogram was taken
and analyzed from it.
Results: The study sample comprised of 52 BCLP patients (26 had PSOA and 26 did
not have PSOA). Among these patients, those who had PSOA had PNS-ANS (3.69 mm;
P = 0.04) and Co-A (8.38; P=0.04) compared to those who did not have PSOA.
Conclusion: The usage of PSOA gives a shorter maxillary length in the facial growth
of bilateral cleft patients.
