Infants with bilateral cleft lip and palate have an esthetic and functional involvement of the face. To obtain esthetic results, such as reducing the cleft gap and mediating premaxilla, various treatments are performed, such as presurgical orthopedics with extraoral traction headgear and nasoalveolar molding. Nasoalveolar molding (NAM) therapy has proven to be an effective method for reducing the cleft, improving the anatomy of the nose and remodeling the alveolar and nasal segments before surgical repair. This article presents two clinical cases with bilateral cleft lip and palate; case 1 treated with presurgical orthopedics with extraoral traction headgear and case 2 treated with NAM therapy.

| Introduction|| |
The cleft lip and palate is one of the most frequent alterations of head and neck. The alterations in the nasal, labial, and dental area produce serious functional problems.
Grayson and Cutting were among the first to combine the concepts of presurgical orthopedics and preoperative treatment of cleft lip nose deformity.
They developed the concept of nasoalveolar molding, which combined a nasal molding stent with a passive preoperative molding apparatus in the treatment of patients with cleft palate.
Nasoalveolar molding (NAM) therapy is a presurgical infant orthopedic technique that reduces the severity of the cleft nasal and deformity before lip and palate surgery.
The principle of NAM is based on the breakdown of the intercellular matrix of nasal cartilage due to the abundance of hyaluronic acid during the first 6–8 weeks of the infant. During this period, there are high levels of maternal estrogen in fetal circulation, which triggers an increase in hyaluronic acid.
- Approximation of lip segments before surgery
- Medialization and retrusion of the premaxilla in the midsagittal plane
- Reduction of severity of cleft of alveolar segments.
| Case Reports|| |
Patients with bilateral cleft lip and palate, nonsyndromic, and collaborating parents.
A 6-day-old female infant was treated at the National Institute of Child Health (Instituto Nacional de Salud del Niño: INSN) in February 2014. In the first visit, after the clinical evaluation, a headgear was made. Parents were given directions. During the second visit, after 4 days, the correct use of the headgear was evaluated. On the third visit, another new headgear was made due to the growth of the infant. A headgear of unilateral traction was used for 1 month, till medialization of premaxilla at the same level of the midsagittal plane then the headgear of bilateral traction was used until a lip surgery.
The results found were approximation of the lip segments, the premaxilla medialized and slightly retruded [Figure 1]a,[Figure 1]b,[Figure 1]c.

A 19-day-old male infant was treated at INSN in March 2015. At the first visit, after the clinical evaluation, the palate was imprinted with heavy silicone, cast in Type IV plaster, and the NAM plaque was made. The acrylic of the plate is 2 mm thick. In the second visit, the patient with 21 days, the plaque was installed without nasal stent. On the third visit, a resilient acrylic was added. On the fourth and fifth check-ups, the wear was performed in areas to promote the bone's growth then acrylic was added in areas where alveolar processes will be redirected. On the sixth check-up, a nasal stent, made of 0.32 steel wire, was placed. Five more controls were performed before surgery, with 7 day interval [Figure 2]c.

The results were approximation of the lip segments, the premaxilla was medialized in the sagittal and retruded in the median plane, transverse growth of the alveolar processes, and the prolabium elongation [Figure 2]a,[Figure 2]b,[Figure 2]c,[Figure 2]d,[Figure 2]e.
| Discussion|| |
Grayson et al. described the first presurgical NAM device. The use of the presurgical apparatus helps in providing a more coalescing slit and a ideally alveolar arch shape. This in turn reduces stress during primary surgery, reducing scar formation. This alignment of the alveolar segments provides the basis for a good lip symmetry that produces more favorable bone formation by reducing the cleft gap.
In this case, when a reduction of 2–3 mm of the alveolar fissure is observed, we placed the nasal stent, with weekly activations.
We observed reduction of the protrusion and deviation of the premaxilla similar to Spengler et al.
Positive effects are observed in infants with bilateral cleft palate alveolus, also described by other authors, Rau et al., Gandedkar et al.
| Conclusion|| |
The NAM therapy is a method which approximates the labial and alveolar segments by the redirection of natural growth forces, offers preoperative reduction of the alveolar cleft, approximation of the lip segments before surgery, which reduces lip tension. It is observed medialization and retrusion of the premaxilla unlike the headgear of traction that only medialized the premaxilla and obtained a slight retrusion.
