Presurgical infant orthopedics has been employed since the 1950s as an adjunctive neonatal therapy for the correction of cleft lip and palate. In this paper, we present a paradigm shift from the traditional methods of presurgical infant orthopedics. Some of the problems that the traditional approach failed to address include the deformity of the nasal cartilages in unilateral as well as bilateral clefts of the lip and palate and the deficiency of columella tissue in infants with bilateral clefts. The nasoalveolar molding (NAM) technique we describe uses acrylic nasal stents attached to the vestibular shield of an oral molding plate to mold the nasal alar cartilages into normal form and position during the neonatal period. This technique takes advantage of the malleability of immature cartilage and its ability to maintain a permanent correction of its form. In addition, we demonstrate the ability to nonsurgically construct the columella through the application of tissue expansion principles. This construction is performed by gradual elongation of the nasal stents and the application of tissue-expanding elastic forces that are applied to the prolabium. Use of the NAM technique has eliminated surgical columella reconstruction and the resultant scar tissue from the standard of care in this cleft palate center.

Objective The purpose of this study was to evaluate if narrowing and approximation of the alveolar cleft through presurgical alveolar molding followed by gingivoperiosteoplasty (GPP) at the time of lip repair reduces the need for a bone-grafting procedure. Design This was a retrospective blind study of patients with unilateral or bilateral alveolar clefts who underwent presurgical infant alveolar molding and GPP by a single surgeon. Alveolar bone formation was assessed prior to the eruption of the maxillary lateral incisor or canine by clinical examination, panoramic and periapical radiographs, and/or a dental CT scan. The criterion for bone grafting was inadequate bone stock to permit the eruption and maintenance of the permanent dentition. Setting This study was performed at the Institute of Reconstructive Plastic Surgery by the members of the Cleft Palate Team. Patients All patients with unilateral (n = 16) or bilateral (n = 2) alveolar clefts who underwent presurgical infant alveolar molding and GPP by a single surgeon from 1985 to 1988 were studied. The control population consisted of all alveolar cleft patients (n = 14) who did not undergo alveolar modeling or GPP during the same time period. Interventions Presurgical alveolar modeling was performed with an intraoral acrylic molding plate. This plate was modified on a weekly basis to align the alveolar segments and close the alveolar gap. The surgical intervention consisted of a modified Millard GPP. Main outcome Measures The primary study outcome measure was the elimination of the need for a secondary bone graft in patients who underwent presurgical alveolar molding and GPP. Results Of the 20 sites in the 18 patients who underwent GPP, 12 sites did not require an alveolar bone graft. Of the 8 sites requiring a bone graft, 4 presented minimal bony defects. All 14 patients in the control group required bone grafts. Conclusions In this series of 20 alveolar cleft sites treated with presurgical orthopedics and GPP, 60% did not need a secondary alveolar bone graft in the mixed dentition.
We present a new combined approach to primary bilateral cleft lip, nose, and alveolus repair using presurgical nasoalveolar molding combined with a one-stage lip, nose, and alveolus repair. Presurgical alveolar molding is used to bring the protruding premaxilla back into proper alignment with the lateral segments in the maxillary arch. Presurgical nasal molding produces tissue expansion of the short columella and nasal lining. A coordinated surgical approach involves a one-stage repair of the lip, nose, and alveolus. The nasal repair uses a retrograde approach in which the prolabial flap and columella are reflected over the nasal dorsum by continuing the dissection behind the prolabium up the membranous septum and over the septal angle. Tissues are dissected out from between the tip cartilages, and the domes are sutured together in the midline. This method joins a new class of bilateral cleft repairs that place the primary emphasis on correction of the deformity of the nasal tip cartilages.
Although benefits outnumber the complications, it is important to address all complications in order to prevent any deleterious outcomes.
