Infant Orthopedics

Presurgical infant orthopedics (PSIO) is done to reduce the size of the cleft defect along with improving the arch alignment and nasolabial aesthetics in patients with cleft lip and palate, leading to an improvement of nasolabial aesthetics allowing for a tidier and more aesthetic reparative procedure and postsurgical scar. Since the 2000s, clear aligners have slowly and steadily treaded their way as an acceptable orthodontic modality, with their usage and acceptability increasing considerably over the past decade. Thus, from the knowledge gathered in its 10 years working with 3-dimensional (3-D) diagnosis, treatment planning, and 3-D Printing services, Compass 3D (Belo Horizonte, Brazil) developed the OrthoAligner NAM system. This case series highlights one of the world’s first documented cases of PSIO treated with a series of clear aligners.

Objective: This study aimed to observe and analyze the effects of nasoalveolar molding (NAM) on maxillary arch dimensions in patients with bilateral complete cleft lip and palate (BCLP) using 3-dimensional analyses. Design: Retrospective case series. Materials and Methods: Seventeen infants were treated using modified Khon Kaen University presurgical nasoalveolar molding devices (KKU-NAM). Dental casts were evaluated 3 dimensionally at 3 time points: pretreatment (T1), after using modified KKU-NAM for 2 weeks (T2), and before cheiloplasty (T3). Repeated-measures analysis of variance and Friedman test were used to compare the maxillary arch dimensions between time points. Results: Both sides of the cleft width, premaxilla deviation, and premaxilla protrusion had significantly reduced with the use of KKU-NAM. Premaxillary rotation had significantly improved, whereas the arch depth did not change significantly. Premaxilla width, posterior arch width, alveolar length, and height had significantly increased. The anterior arch width, intercanine width, and lateral sulcus width showed no significant changes. The intraclass correlation coefficient used to test the measurements indicated substantial reliability. Conclusion: The modified KKU-NAM is an effective device for reducing the severity of bilateral cleft deformities, especially in the premaxilla area.

Objective: To determine the current applications of 3-dimensional (3D) printing in the care of patients with cleft lip and palate. We also reviewed 3D printing limitations, financial analysis, and future implications. Design: Retrospective systematic review. Methods: Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines were used by 3 independent reviewers. Articles were identified from Cochrane library, Ovid Medline, and Embase. Search terms included 3D printing, 3 dimensional printing, additive manufacturing, rapid prototyping, cleft lip, and cleft palate. Exclusion criteria included articles not in English, animal studies, reviews without original data, oral presentations, abstracts, opinion pieces, and articles without relevance to 3D printing or cleft lip and palate. Main Outcome Measures: Primary outcome measure was the purpose of 3D printing in the care of patients with cleft lip and palate. Secondary outcome measures were cost analysis and clinical outcomes. Results: Eight-four articles were identified, and 39 met inclusion/exclusion criteria. Eleven studies used 3D printing models for nasoalveolar molding. Patient-specific implants were developed via 3D printing in 6 articles. Surgical planning was conducted via 3D printing in 8 studies. Eight articles utilized 3D printing for anatomic models/educational purposes. 3-Dimensional printed models were used for surgical simulation/training in 6 articles. Bioprinting was utilized in 4 studies. Secondary outcome of cost was addressed in 8 articles. Conclusion: 3-Dimensional printing for the care of patients with cleft lip and palate has several applications. Potential advantages of utilizing this technology are demonstrated; however, literature is largely descriptive in nature with few clinical outcome measures. Future direction should be aimed at standardized reporting to include clinical outcomes, cost, material, printing method, and results.

AbstractCleft lip and palate patients are born with a challenging deformity that requires multiple surgical interventions in order to reach functional and esthetic harmony. Mid face deficiency in cleft patients is a challenging clinical problem very often encountered in the management of this congenital defect. Cleft maxillary hypoplasia can be attributed to the inherited traits, acquired traits and Induced traits. CLP patients usually present with symptoms varying from malocclusion, retrusion of midface, and a narrow hard palate. A detailed evaluation and individualized treatment planning is of utmost importance in dealing with these patients. Treatment involves the contribution from both the orthodontist and the craniofacial team. The goals for the treatment for cleft maxillary hypoplasia are improvement of aesthetic deficits as well as correction of malocclusion.

Epignathus is a rare congenital orofacial teratoma that arises from the sphenoid region of the palate or the pharynx. It occurs in approximately 1:35,000 to 1:200,000 live births representing 2% to 9% of all teratomas. We present the case of a newborn of 39.4 weeks of gestation with a tumor that occupied the entire oral cavity. The patient was delivered by cesarean section. Oral resection was managed by pediatric surgery. Plastic surgery used virtual 3-dimensional models to establish the extension, and depth of the tumor. Bloc resection and reconstruction of the epignathus were performed. The mass was diagnosed as a mature teratoma associated with cleft lip and palate, nasoethmoidal meningocele that conditions hypertelorism, and a pseudomacrostoma. Tridimensional technology was applied to plan the surgical intervention. It contributed to a better understanding of the relationships between the tumor and the adjacent structures. This optimized the surgical approach and outcome.

Infant Orthopedics

ABSTRACTPresurgical infant orthopedics has been employed since 1950 as an adjunctive neonatal therapy for the correction of cleft lip and palate. Most of these therapies did not address deformity of the nasal cartilage in unilateral and bilateral cleft lip and palate as well as the deficiency of the columella tissue in infants with bilateral cleft. The nasolaveolar molding (NAM) technique a new approach to presurgical infant orthopedics developed by Grayson reduces the severity of the initial cleft alveolar and nasal deformity. This enables the surgeon and the patient to enjoy the benefits associated with repair of a cleft deformity that is minimal in severity. This paper will discuss the appliance design, clinical management and biomechanical principles of nasolaveolar molding therapy. Long term studies on NAM therapy indicate better lip and nasal form, reduced oronasal fistula and labial deformities, 60 % reduction in the need for secondary alveolar bone grafting. No effect on growth of midface in sagittal and vertical plane has been recorded up to the age of 18 yrs. With proper training and clinical skills NAM has demonstrated tremendous benefit to the cleft patients as well as to the surgeon performing the repair.

Objectives: The aim of this study is to know the prevalence, type of congenital heart diseases (CHDs), and its association with cleft lip and/or palate and to know the impact of CHDs on surgical treatment planning of cleft lip and palate from a craniofacial hospital specializing in orofacial clefts, head and neck cancer, and trauma management. Design: A total of 1381 patients with nonsyndromic cleft lip and palate were included in the study. This is a hospital-based retro–prospective case record analysis. The data were collected from clinical records of the patients which included clinical, chest radiographic and 2D echocardiographic findings. Total incidence of CHDs and its impact on treatment planning was evaluated using κ statistics and χ2 test. Results: There were 32 (2.32%) cleft lip and palate patients with CHDs. In 2 patients, cleft surgery was delayed by 6 to 9 months to allow the defect to decrease in size. Subacute bacterial endocarditis prophylaxis was administered in 7 patients before cleft surgery. Cardiac surgery was advised prior to cleft surgery in 3 patients. Sixteen patients with CHDs were not taken for cleft surgery considering the potential risk to the patient’s life as they had multiple cardiac anomalies. There were no intraoperative and postoperative complications in these patients. Conclusion: The results emphasize the association between clefting and CHD. The collected data suggest that there should be careful examination of children with cleft lip and palate for signs of heart disease. This could significantly reduce the morbidity/mortality of cleft lip and palate surgery making it more predictable and safer.
