Extraoral nasal molding in a newborn with unilateral cleft lip and palate: a case report

Pre-surgical Nasal Molding of a Two-Day-Old Neonate With Complete Unilateral Cleft Lip and Palate Using Passive Nasoalveolar Molding Technique: A Case Report

The occurrence of congenital deformities like cleft lip and palate is not uncommon and is often a traumatizing experience for families. The entire rehabilitation process includes frequent hospital visits and the brunt of numerous procedures. Early intervention with pre-surgical infant orthopedics facilitates better surgical outcomes and additional psychosocial benefits to the infant's family. The present clinical report addresses the pre-surgical management of a non-syndromic two-day-old female baby whose parents presented with the chief complaint of deformed lips, nose, and difficulty while feeding. The neonate had a complete left-sided cleft lip, alveolus, and cleft palate on examination. Early management with pre-surgical passive nasoalveolar molding (PNAM) has favorable outcomes, including desired upper lip, alveolus, and nose shape. Non-invasive pre-surgical intervention with PNAM reduces the severity of the deformities before the primary surgical repair, thus decreasing the overall cost of cleft care and the number of secondary revisions, thus increasing the probability of favorable outcomes.

Recent Advances in Nasoalveolar Molding Therapy Using 3D Technology

Presurgical Nasoalveolar Molding (NAM) is an adjunctive treatment modality designed to reorient misaligned tissue structures and nasal cartilage in cleft lip and/or palate (CL/P) patients. Recent advances in NAM therapy focus on modifications to the intraoral molding plate or nasal stent intended to improve treatment outcomes, ease of use, compliance, and cost-effectiveness. Notably, 3D technological advancements have been employed to design NAM devices more efficiently and create objective, standardized means of measuring progressive morphological changes during therapy. These advances are designed to incorporate 3D technology in the treatment of cleft lip and/or palate to render it more precise, accurate, and time-efficient.

Primary care in early cleft lip and palate rehabilitation: A dental perspective

Oro-facial clefts are among the most commonly occurring congenital defects. Surgical interventions are commonly carried out to treat these deformities. Some inadequacies however, like scarring of the nasolabial complex and multiple interventions to achieve desired results still persist. Presurgical Nasoalveolar molding (PNAM) technique can be carried out before surgical repair, to facilitate a reduction in the severity of the cleft by actively molding and repositioning the clefted alveolar segments and the associated soft tissues. This case series describes the successful rehabilitation of two unilateral mid-facial cleft babies using the PNAM technique in a step wise manner with a two year follow up.

A modified presurgical alveolar molding technique for treatment of cleft in Down syndrome

Craniofacial clefts are extremely rare deformities. Tessier’s classification is a widely accepted system that is based on clinical, radiographical, and surgical observations. The Tessier No. 0 cleft most commonly affects the upper lip, nose, and palate. This case presentation aims to report the outcome of a modified presurgical alveolar molding (PAM) appliance used in the treatment of an infant with Tessier No. 0 cleft as an alternate approach to mold such defects before surgery. The modified PAM appliance consisted of reciprocal parts connected by a helix. The segments were approximated by stripping the appliance at the midline in a V-shaped manner and the force was exerted by the extraoral elastics. The procedure gave results in 8 weeks, which may be regarded as a reasonable duration. The anterior cleft gap, which was 13 mm before the treatment, was reduced to 3 mm after the treatment by using modified PAM appliance. On a 21-month follow-up period, oral reshaping was regarded successful due to stability of the improved oral mold.

Comparative evaluation of nasal and alveolar changes in complete unilateral cleft lip and palate patients using intraoral and extraoral nasoalveolar molding techniques: randomized controlled trial

Objectives

Cleft lip and palate is a common congenital anomaly that impairs the aesthetics, speech, hearing, and psychological and social life of an individual. To achieve good aesthetic outcomes, presurgical nasoalveolar molding (NAM) has become important. Currently, the intraoral NAM technique is widely practiced. Numerous modifications have been made to intraoral NAM techniques, but the original problem of compliance leading to discontinuation of treatment remains unsolved. Therefore, the present study compared an extraoral NAM technique with the intraoral NAM technique.

Materials and Methods

Twenty infants with complete unilateral cleft lip and palate were included and divided into two equal groups. Group A received the intraoral NAM technique, and Group B received the extraoral NAM technique. Pre- and postoperative extraoral and intraoral measurements were recorded.

Results

Groups A and B did not differ significantly in any extraoral or intraoral parameter.

Conclusion

The extraoral NAM technique is as effective as the intraoral NAM technique in achieving significant nasal and alveolar changes in com-plete unilateral cleft lip and palate patients. Additionally, it reduces the need for frequent hospital visits for activation and the stress associated with the insertion and removal of the intraoral NAM plate, thereby improving compliance.

The Effectiveness of Preoperative Correction Techniques in Improving Nasal Deformity in Children With Unilateral Complete Cleft Lip and Palate

OBJECTIVE

Unilateral complete cleft lip and palate (UCCLP) is associated with apparent nasal deformities before the cheilorrhaphy. The aim of this study was to determine whether preoperative correction techniques are effective in the treatment of nasal deformities in infant with unilateral UCCLP used by the systematic review and meta-analysis.

METHODS

We searched Medline, Cochrane Library, EMBASE, PubMed, and Chinese BioMedical Literature Database (CBM) until January 31, 2019, to identify studies that compared the effectiveness of preoperative correction techniques in the treatment of nasal deformities in infant with UCCLP. Two authors individually extracted the data and performed the quality assessments. The height of nasal columella, the width of the affected side nasal ala and the inclination of the nasal columella were evaluated.

RESULTS

Seven articles were incorporated into the systematic review, and 5 (274 participants) in the meta-analysis according to the inclusion criteria. The preoperative correction could increase the height of nasal columella in children with UCCLP [SMD: 2.64 mm; 95% confidence intervals (CI); (1.35 mm, 3.94 mm); P < 0.0001]. Moreover, the preoperative correction resulted in reduced width of the affected side nasal ala [SMD: -5.14 mm; 95% CI; (-8.96 mm, -1.31 mm); P = 0.008]; However, the evidence was insufficient to determine a significant effect on the inclination of the nasal columella [SMD: -3.48 degrees; 95% CI; (-7.56 degrees, 0.59 degrees); P = 0.09].

CONCLUSIONS

Preoperative correction for children with UCCLP can increase the height of nasal columella, reduce the width of the affected side nasal ala, improve the nasal symmetry, and reduce nasal deformity, however, no significant effect could be observed for the inclination of the nasal columella.

A New Approach to Presurgical Nasoalveolar Molding in Patients With Unilateral Cleft Lip and Palate and Severe Cleft Width

The aim of this study was to describe a new approach to the presurgical orthopedic treatment of unilateral cleft lip and palate patients with severe cleft width. Modified nostril retainers manufactured from soft acrylic were used for the nasal molding. This technique enables the separation of the nasal molding without having to reduce the cleft width to 5 mm. Nasal molding with the modified nostril retainer resulted in the patient and the physician experiencing a more comfortable treatment period.

Presurgical Preparation of Infants With Unilateral Cleft Lip and Palate: The SAC-PP-MR Innovative Technique

In this article, we demonstrate an effective, cheap, and fast way to shape the nasal alar cartilage in patients with unilateral cleft lip and palate. This technique straightens the vomer and brings the philtrum, columella, premaxilla, and the maxillary frenum to the midsagittal plane, while the alveolar ridges are shaped and positioned. This reduces the lip and palatal cleft to zero even in a 4-week period.

Presurgical Dentofacial Orthopedic Management of the Cleft Patient

Over the last decade, presurgical orthopedic molding for the patient with cleft lip and palate has become much more common; it is even reasonable to assume it may be the standard of care for those wide unilateral and bilateral clefts with substantial dentofacial deformities. In 2013, there was a comparative study of nasoalveolar molding methods, comparing the Grayson-NAM device and DynaCleft. The results showed the 2 to be equivocal with both methods significantly reducing the cleft width and improving the nasal asymmetry.

Simplifying cleft surgery by presurgical nasoalveolar molding (PNAM) for infant born with unilateral cleft lip, alveolus, and palate: a clinical report

PATIENT

A 2-day-old female infant with complete unilateral cleft lip, alveolus, and palate (left side) was presented to the Department of Prosthodontics, Government Dental College and Hospital, Nagpur for evaluation and treatment with presurgical nasoalveolar molding (PNAM) prior to surgical intervention.

DISCUSSION

The alignment of the alveolar segments creates the foundation upon which excellent results of primary lip and nasal surgery are dependent in the repair of the cleft lip, alveolus, and palate patient. Presurgical infant orthopedics has been employed since the 1950s as an adjunctive neonatal therapy for the correction of cleft lip and palate. One of the problems that the traditional approach failed to address was the deformity of the nasal cartilages and the deficiency of columella tissue in infants with unilateral and bilateral cleft lip and palate. The purpose of this article is to illustrate the step-by-step fabrication process of the PNAM prosthesis used to direct growth of the alveolar segments, lips, and nose in the presurgical treatment of cleft lip and palate.

CONCLUSION

As a result, the primary surgical repair of the lip and nose heals under minimal tension, thereby reducing scar formation and improving the esthetic result. Frequent surgical intervention to achieve the desired esthetic results can be avoided by PNAM.

Presurgical nasoalveolar molding assisted primary reconstruction in complete unilateral cleft lip palate infants

BACKGROUND

Various methods have been described for the primary surgical reconstruction of the unilateral cleft lip and palate deformity (UCLP) in infants. There have been several attempts at restoring the normal anatomy of the nose at the time of lip repair in the affected individuals with varying degrees of success. Presurgical nasoalveolar molding (PNAM) is a presurgical infant orthopedic procedure that attempts to target the nasal deformity leading to a more esthetic surgical repair.

OBJECTIVE

At our center we aimed to use PNAM to help in providing the surgical team with a better foundation for an easier and more esthetic single stage repair at the level of nose in addition to the lip and alveolus.

METHOD

The infant nasal cartilages are amenable to correction in the first few weeks of life when they retain their plasticity. Three infants with complete unilateral cleft lip palate (CUCLP) were operated upon after a course of PNAM. No nasal stents were use after repair to retain the results.

RESULTS

PNAM reduced the extent of the cleft deformity and improved the anatomic relationship between the affected structures. Postoperative recovery was uneventful. Subjective evaluation immediate post surgery and at the time of palate repair reveals adequate nasolabial esthetics. Long-term results of PNAM assisted repair are to be ascertained.

CONCLUSIONS

The use of PNAM enables in reducing the severity of the deformity the surgical team has to tackle thereby enabling in a better and esthetic primary repair.

Design features and simple methods of incorporating nasal stents in presurgical nasoalveolar molding appliances

Presurgical nasoalveolar molding (NAM) in the orofacial orthopedic treatment of unilateral clefts of the lip and palate aims to align and approximate the maxillary hemialveolar segments and simultaneously support and mold the deformed nasal cartilages, correct and center nasal tip projection, and lengthen the deficient cleft-side columella in early infancy, before the primary reparative lip surgery. A number of techniques of achieving these objectives have been described in the literature and are increasingly being practiced by cleft care teams around the world. However, a detailed description of the nasal stent is lacking in the literature and needs to be elucidated to facilitate greater usage of presurgical NAM in contemporary practice. This report fills this void by providing an analytical description of the different parts of the nasal stent; clarifies their desirable design features, anatomic correlations, and clinical importance; and illustrates in a step-by-step manner simple direct and indirect methods of incorporating a nasal stent, improvised by the author in his practice, that can be used with any of the contemporary NAM appliances and techniques. From the simple methods described, clinicians will be enabled to select one that may be most easily adaptable to their preferred appliance and clinical setting.

Complications and solutions in presurgical nasoalveolar molding therapy

OBJECTIVE

To outline three main categories of nasoalveolar molding complications, describe their etiologies and manifestations, and prescribe preventive and palliative therapy for their proper management. Estimates of the incidence of each complication also are provided.

MATERIALS AND METHODS

Data were collected retrospectively from the charts of 27 patients with complete unilateral cleft lip and palate treated by the first author (D.L.-B.) at the University of Puerto Rico (n = 12) and the Medical College of Georgia (n = 15). Confidence intervals for the true incidence of each complication were calculated using exact methods based on the binomial distribution. A significance level of .05 was used for all statistical tests.

RESULTS

Of the soft and hard tissue complications considered, only one (tissue irritation) had an estimated incidence greater than 10%. Compliance issues were of greater concern, with an estimated incidence of 30% for broken appointments and an estimated incidence of 26% for removal of the nasoalveolar molding appliance by the tongue.

CONCLUSIONS

Although benefits outnumber the complications, it is important to address all complications in order to prevent any deleterious outcomes.

Presurgical nasoalveolar molding in patients with unilateral clefts of lip, alveolus and palate. Case study and review of the literature

INTRODUCTION

The case of a newborn female patient with unilateral cleft lip, alveolus and palate is presented with a markedly sunken nasal wing at the cleft side. This finding may lead to a very unsatisfactory aesthetic result after primary cheiloplasty and nasoplasty.

PATIENT AND METHOD

Five months prior to surgery, the patient was treated with a palatal plate and additionally with a nasoalveolar conformer for 4 months thereof. The device consisted of an acrylic pelotte (attached to the maxillary plate with a wire) which lifted the nasal dome and was activated regularly. Under this presurgical treatment, the cleft edges moved closer to each other by 1.8 mm at the alveolar ridge and by 4.5 mm in the palatal area. The nasal wing was lifted by 5 mm. This was enabling elevation of the nasal wing during primary surgery in the case described. Questions are raised as to the remaining effects on nasal symmetry until completion of growth and, on the other hand, as to the chances to reduce postsurgical alar relapse by continued nasal molding beyond primary surgery.

CONCLUSION

Presurgical nasal molding seems to improve aesthetics of the nose in patients with unilateral clefts of lip, alveolus and palate and distinctly flattend nasal wings.
