Evaluation of Nasal Changes after Using Modified Nasoalveolar Molding in Complete Unilateral Cleft Lip and Palate Patients
Keywords:Complete unilateral cleft lip and cleft palate, Nasoalveolar molding, Denture adhesives
Background: Nasoalveolar molding (NAM) is a pre-surgical treatment that is used to reduce the severity of the cleft deformity in order to facilitate primary surgical repair. Denture adhesive has been used to secure and improve retention of the NAM appliance however it could contribute to harmful effects including cytotoxicity, irritation, and infection.
Objectives:To evaluate the nasal outcomes of modified NAM therapy in patients with complete unilateral cleft lip and palate (UCLP) without denture adhesive.
Methods: A prospective cohort study was conducted. Eight UCLP patients who received modified NAM at Queen Sirikit national institute of child health were included in this study. Standard basilar view photographs were taken. Measurements of nostrils height, nostril width, columella angle, nasal base angle were performed. Statistical analyses were used to compare the differences between pre and post therapy measurements.
Results: After modified NAM therapy, there was a statistically significant increase in nostril height and columella angle with the differences of 2.38 mm. and 36.30 degree (p < 0.05) respectively. There was also a statistically significant decrease in nostril width with the differences of 3.27 mm. (p < 0.05).
Conclusions: A favorable outcomes of modified NAM therapy were achieved. It is promising that modified NAM can be used as effective as other conventional NAM appliances without denture adhesive required.
