The success of repair in cleft lip and palate depends on the extent of disfigurement and the size of disfigurement which guides the surgical repair. With the popularization of nasoalveolar molding (NAM), the results of primary surgery in such patients have greatly improved due to the presurgical correction of the deformities leading to a better approximation of the tissues and hence reduced scarring. Thus, today, the knowledge of pre-surgical nasoalveolar molding should be a part of any orthodontist's armamentarium to enhance the results of surgical lip repair and reduce the extent of nasal deformity minimizing the need for revision surgeries. The current report describes the use of NAM in a newborn with unilateral cleft lip and palate and demonstrates the excellent results thus achieved after surgical repair.

| Introduction|| |
Orofacial clefts are the second most common birth anomaly. Incidence of cleft lip/palate in India-27,000–33,000/year, i.e., 78 infants/day or 3/h., With the popularization of nasoalveolar molding (NAM), the orthodontist today plays a pivotal role in managing cleft patients as early as immediately after birth. The first pre-surgical NAM (PNAM) appliance was given by Grayson et al. in 1999. The principles of PNAM therapy are based on Matsuo's research that the nasal cartilage continues to develop and is subject to repositioning till the first 6 weeks of life. This is due to the presence of maternal estrogen in the infant till 6 weeks which increases the cartilage content of hyaluronan, a component of the proteoglycan extracellular matrix, thus increasing the moldability of the nasal cartilage.
The present case demonstrates the success of NAM in the management of a newborn with unilateral cleft lip and palate and stability of results 2 years postsurgery.
| Case Report|| |
A male child, 1 months 18-day-old, was referred to the outpatient department for presurgical orthopedics to facilitate the surgical repair of the cleft of lip and palate [Figure 1]. The patient had a unilateral cleft lip and palate on the right side with simonart's band traversing through the cleft. The right alar dome was depressed and the nose was flattened on the right side. The nasal septum was deviated, and right nostril was elongated. Thus, NAM was planned for the patient to reduce the distance between the cleft alveolar segments, bring lips in closer approximation for ease of surgical repair, upright the deviated septum and improve the right nasal contour.
An impression was made with putty in the Pediatric Intensive Care Unit as a precaution to manage any airway emergency. The patient was held in mother's lap with the face at a lower level than the rest of the body. The impression was made after waiting for 1½ hours of feeding to avoid emesis of milk. An alveolar molding appliance was fabricated with cold cure acrylic resin and instructions were given for appliance wear [Figure 2]. The appliance was retained in place with bilateral elastics taped onto the cheeks. To save the patient's skin from any ulceration due to repeated placement and removal of the surgical tapes, a protective layer of Tegaderm (3M) was placed on the cheeks over which retentive tapes were placed [Figure 3]. The parents were instructed to increase the time of wear of the appliance gradually from 4 to 6 h to full-time wear for easy adaptation by the infant in 3 days. The patient was recalled after 3 days to assess for any ulceration or resolve any difficulty in the use of the appliance. This was followed by weekly appointments in which sequential addition of the silicone based relining material was done along with trimming of the acrylic of the appliance where the alveolus had to be molded [Figure 4]. Furthermore, expansion of the arches was done simultaneously in the same way. After 3 weeks, the larger segment was molded into proximity to the lesser segment and at this stage, nasal stent was planned to be added to the appliance. However, the molding appliance was refabricated due to loss of the layer of silicone material in part and a nasal stent was added to this new appliance [Figure 5]. The nasal stent lifted the right nasal dome with horizontal taping to allow for stretching of the columella and uprighting of the nasal tip. The presurgical approximation of oral tissues demonstrating the success of NAM therapy are given in [Figure 6] after which the surgical repair of the lip was done [Figure 7] The results of the lip repair were excellent with good stability 2 years after surgery [Figure 8].

| Discussion|| |
The main objectives of the NAM technique involve repositioning of the deformed nasal cartilage and alveolar segments. Thus, segments can come in closer approximation resulting in reduction in the volume of which facilitates surgical repair and lesser resultant scarring. In the case of the bilateral cleft, columellar elongation is another important aim of the NAM. Hence, the benefits of PNAM or similar orthopedic appliances include to be the improvement in arch form, ease of surgical repair, better aesthetic outcome, facilitation of feeding, and improvement of speech.,, The long-term benefits of NAM include better arch form, improved chances of tooth eruption with good periodontal support, reduced need for revision surgeries and most importantly better psychosocial status of the patient.
The timing for initiation of NAM therapy has been advocated to be within the 1st week of birth. However, in this case, NAM was carried out successfully in a 1½-month-old infant. This is supported by a study by Mishra et al. who have reported good results of carrying out NAM in infants from 10 to 360-day-old though the amount of changes brought about reduce with increasing age. Thus, the child was not denied the presurgical NAM the beneficial results of which are evident even 2 years after the surgical repair.
| Conclusion|| |
The current case describes in detail the steps for presurgical NAM for a case of unilateral cleft lip and palate in a newborn male patient with excellent postsurgical results. Hence, it helps the orthodontists in practicing this technique for attaining better postsurgical results of cleft lip repair in their patients.
