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

Three-dimensional analysis of presurgical nasoalveolar molding outcomes in patients with unilateral cleft lip and palate: A preliminary study using LED surface scanning technology

OBJECTIVES

Presurgical infant orthopedic appliances, such as presurgical nasoalveolar molding (PNAM) devices, are used to attain optimal conditions for primary repair of the lip and nose (PRoLN) in patients with cleft lip. We aimed to analyze the three-dimensional (3D) outcomes of PNAM using an LED surface scanner.

METHODS

Fifteen patients with unilateral cleft lip and palate (CLP) were included in this study and treated using a PNAM device. The patients' faces were digitized pre- and post-PNAM using an Artec Space Spider scanner, and the scanned data were analyzed using 3D software (Geomagic Control X and ANSYS SpaceClaim). The columellar angle (CA), nostril curvature (NC) on the affected (NC_A) and unaffected (NC_U) sides, gap of cleft lip (GCL), alar width (AW), and nasal tip angle (NTA) were measured.

RESULTS

CA increased significantly by 10.00° and NC_A by 0.030 mm-1 (p < 0.001). GCL decreased by 4.98 mm2 on average and NC_U by 0.015 mm-1 (p = 0.029 and 0.046, respectively). AW also decreased by approximately 1.22 mm pre- and post-treatment (p = 0.002), and NTA, which shows a lateral profile, decreased by approximately 3.32° (p = 0.002).

CONCLUSIONS

This study confirmed the orthopedic benefits of PNAMd treatment through 3D analysis using an LED surface scanner. Further studies involving a larger number of participants are warranted to study the effects of PNAM and analyze longitudinal changes in patients with CLP.

CLINICAL SIGNIFICANCE

This study shows that PNAM effectively corrects columellar deviation and nostril shape in patients with unilateral cleft lip, with 3D scanners enhancing primary lip and nose repair outcomes.

A cross-sectional analysis of the content and quality of presurgical infant orthopedics videos on YouTube

BACKGROUND

Caregivers seeking additional information about Presurgical Infant Orthopedics (PSIO) may turn to online sources, but the quality of information on platforms like YouTube is uncertain.

AIM

To investigate the content and quality of PSIO videos on YouTube.

DESIGN

YouTube videos were searched using keywords related to PSIO appliances. Videos that met the eligibility criteria (n = 52) were categorized as care provider or caregiver-based. Engagement metrics were analyzed and quality assessments were performed by two raters using the Global Quality Score (GQS), Video Information and Quality Index (VIQI), and Medical Quality Video Evaluation Tool (MQ-VET).

RESULTS

Inter-rater and intra-rater correlations were high (r ≥0.9; p < 0.01), indicating excellent reliability. Strong correlations were observed between the GQS, VIQI, and MQ-VET scores (r: 0.86-0.91; p < 0.01). Mean GQS (2.7 ± 1.1), VIQI (13.0 ± 4.1), and MQ-VET (42.6 ± 12.4) scores indicated poor to moderate video quality. Most videos (73.1%) were in the care provider category and rated significantly higher (p < 0.05) in quality than the caregiver category for all three indices, but not for video engagement metrics.

CONCLUSION

YouTube PSIO videos are not comprehensive and lack quality. Caregivers of infants undertaking PSIO should seek advice from care providers and not rely solely on YouTube videos.

Using an Active Screwed Nasoalveolar Molding Device for Defect Rehabilitation in Patients With Bilateral Cleft Lip and Palate

The present case series aimed to assess non-surgical elongation of the columella and reduction of cleft gaps in patients with bilateral cleft lip and palate using the active nasoalveolar molding (ANAM) device and tissue expansion principles. The study included six complete bilateral cleft patients aged one month: three males and three females. A nasoalveolar molding technique was applied using an active device (ANAM) with a 3D screw, worn by infants for two months. The activation protocol for screw closure is approximately 0.25 mm (quarter turn) on alternating days, resulting in almost 1 mm per week and 4 mm per month and reaching 8 mm after eight weeks. Evaluation involved measuring lip defect sizes and the nostril gap, columellar length and rotation of premaxilla before and two months after the ANAM period before surgical repair. The results show that the anterior rotation of the premaxilla and the lip and nostril gaps were significantly reduced (p < 0.05), with maximum reduction in the anterior rotation of the premaxilla (mean difference ± SD was 4.22 ± 0.4). Simultaneously, the columellar height was significantly increased with a mean difference ± SD of 2.0 ± 0.4 (p < 0.001). The current case series demonstrated that the ANAM device is a safe and effective technique for decreasing the lip and nostril gaps, repositioning the protruded premaxilla, and elevating the depressed columella. No side effects were recorded in current cases.

Presurgical Orthopedic Nasoalveolar Molding in Cleft Lip and Cleft Palate: Case Report

Aim and objective

The present clinical report describes management of complete unilateral cleft lip and palate with presurgical nasoalveolar molding (NAM) therapy for infants.

Background

Orofacial clefts have a negative impact on the health and social integration of individuals affected. Patients undergo numerous procedures until they reach adolescence. The ultimate focus of surgical intervention is to improve the esthetic appearance of the lip and nose by improving the lip scar, nasal tip projection, and symmetry of the nasolabial complex.

Case description

This paper discusses a situation in which the parents of a three days old baby with the chief complaint of regurgitation of milk while feeding. On examination, baby had complete left-sided cleft lip and cleft palate (CL+CP).

Conclusion

Before surgery, nasoalveolar molding has been shown to be a useful adjunctive therapy for reducing hard and soft tissue cleft deformity.

Clinical significance

Passive preoperative intervention of the lip and alveolar segments helps to reduce tissue tension and is thought to improve surgical outcomes by minimizing wound healing disturbances and scarring.

Comparison of Microbial Activity Among Infants With or Without Using Presurgical Nasoalveolar Molding Appliance

PURPOSE

The aim of the current study is as follows: (1) to study whether wearing the presurgical nasoalveolar molding appliance (PNAM) had facilitated the establishment of Streptococcus mutans and Lactobacillus (LB) and to determine other factors including pH and caries susceptibility associated with wearing the PNAM.

METHODS

Saliva samples of 61 infants (4.5 ± 2.06 months old) were collected from the following 3 groups: PNAM (n = 23), healthy (n = 30), and cleft lip and palate (CLP) without any treatment (n = 8). Saliva samples were assessed using selective agar to enumerate total LB and S mutans and subjected to adenosine triphosphate (ATP)-driven bioluminescence determinations using a luciferin-based assay system, and pH level was evaluated. One-way analysis of variance with least significant difference post hoc test (P < .05) and Pearson correlation were used to evaluate S mutans, LB, pH, and ATP levels.

RESULTS

A total of 63 patients (30 healthy patients, 23 patients with cleft lip/palate who had PNAM appliance and 8 patients with cleft lip/palate who did not use the appliance) were seen in this study. There is a significant difference in pH (P = .012), LB Caries Risk Test (P < .001), LB colony count (P < .001), S mutans Caries Risk Test (P < .001), and S mutans colony count (P < .001) among the 3 groups (PNAM > CLP > healthy). The ATP level was not significantly different among the 3 groups.

CONCLUSION

Higher bacterial count and lower pH were found in the PNAM group. Cleft lip and/or palate patients wearing the PNAM appliance are at higher risk for dental caries.

Evaluation of a Digital Protocol for Pre-Surgical Orthopedic Treatment of Cleft Lip and Palate in Newborn Patients: A Pilot Study

The aim of this study was to evaluate the accuracy, invasiveness and impact on clinical results of a digital oral impression protocol in the pre-surgical orthopedic treatment (PSOT) of newborn cleft lip and palate (CLP) patients undergoing primary alveolar surgical repair. Six patients were divided, according to impression technique used, into a digital (intraoral scanner (IOS)) and a non-digital (tray and putty (T&P)) group. Parents considered IOS impressions to be less invasive, compared to T&P impressions. The clinician that took all the impressions considered the IOS to be less stressful compared to the T&P method. In two T&P patients, the impression was repeated because some important anatomical details were missing, in one case due to patient regurgitation during the first attempt. No impression was repeated, and any adverse event was reported in the IOS group. There were no significant differences between these two protocols in pre-surgical alveolar gap reduction and surgical challenge. The study results indicate that this digital protocol can accelerate the production process of the passive molding plate with an instantaneous transmission of the digital impression to the dental lab, maintaining the same accuracy level and clinical outcomes of classical techniques and reducing the invasiveness of impression taking, avoiding any risk of impression material ingestion or inhalation.

Presurgical nasoalveolar molding with 3D printing for a patient with unilateral cleft lip, alveolus, and palate

An 8-day-old male infant with unilateral cleft lip, alveolus, and palate had a wide alveolar defect, soft tissue deformity, and a markedly sunken nasal wing at the cleft side. The patient was treated with a series of 3D-printed molding plates and synchronously with a nasal hook. The cleft edges moved closer by 9 mm at the alveolar ridge and the nasal wing was lifted considerably. Split-type 3D printing of presurgical nasoalveolar molding helped to reduce the cleft gap, improve the arch form, approximate lip segments, and distinctly improve the morphology of the nose by correcting the flattened nasal wings.

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.

Nasal Obstruction in Children With Cleft Lip and Palate: Results of a Cross-Sectional Study Utilizing the NOSE Scale

OBJECTIVE

To characterize the epidemiology and risk factors for nasal obstruction among subjects with cleft lip and/or cleft palate (CL/P) utilizing the well-validated Nasal Obstruction Symptom Evaluation (NOSE) survey.

DESIGN

Retrospective cross-sectional study.

SETTING

Cleft Lip and Palate Program, Children's Hospital of Philadelphia.

PATIENTS, SUBJECTS

One thousand twenty-eight surveys obtained from 456 subjects (mean age: 10.10 (4.48) years) with CL/P evaluated between January 2015 and August 2017 with at least 1 completed NOSE survey.

INTERVENTIONS

Nasal Obstruction Symptom Evaluation surveys completed at each annual visit.

MAIN OUTCOME MEASURES

Composite NOSE and individual symptom scores.

RESULTS

Sixty-seven percent of subjects had nasal obstruction at some point during the study period, with 49% reporting nasal obstruction at latest follow-up. subjects aged 14 years and older reported the most severe symptoms ( P = .002). Subjects with cleft lip and alveolus (CL+A) and unilateral cleft lip and palate (CLP) reported more severe nasal blockage than other phenotypes ( P = .021). subjects with a history of either posterior pharyngeal flap (PPF) or sphincter pharyngoplasty (SP) had significantly higher NOSE scores than subjects with no history of speech surgery ( P = .006). There was no significant difference ( P > .050) in NOSE scores with regard to history of primary tip rhinoplasty, nasal stent use, or nasoalveolar molding.

CONCLUSIONS

There are more severe nasal obstructive symptoms among subjects older than 14 years of age, with CL+A or unilateral CLP, and with a history of PPF or SP. Future studies utilizing the NOSE are needed to evaluate and address this prevalent morbidity in the CLP population.

Initial experiences with NAM-assisted primary repair of the BCLP deformity

BACKGROUND

Primary surgical repair of the bilateral cleft lip and palate (BCLP) deformity is challenging. Infant Orthopedic (IO) procedures are often used to assist surgical reconstruction of normal anatomy. Nasoalveolar molding (NAM) is a presurgical infant orthopedic procedure that attempts to reduce the cleft nasal deformity, in addition to the lip and alveolus, leading to an esthetic primary surgical repair.

OBJECTIVE

NAM provides 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

Infant nasal cartilages are amenable to correction with NAM in the first few weeks of infancy when they retain their plasticity. NAM-assisted surgical repair of a complete BCLP infant is discussed. Postoperatively nasal stents were used to retain results and minimize relapse.

RESULTS

NAM helped correct premaxillary deviation and protrusion, reduce alveolar cleft width and improve the nasal morphology prior to surgery in the BCLP infant.

CONCLUSIONS

NAM helped reduce the severity of the cleft deformity in the BCLP infant and facilitated an easier and esthetic single stage primary surgical repair.

Parental experience caring for cleft lip and palate infants with nasoalveolar moulding

AIM

The aim of this study was to explore the experience of parents caring for an infant with a cleft lip and palate receiving nasoalveolar moulding.

BACKGROUND

Nasoalveoral moulding is a pre-surgical orthopedic appliance used to approximate an infant's cleft lip and palate, mould the nose and reduce surgical correction. Use of nasoalveolar moulding can be intensive, costly and lengthy requiring parental commitment to the process since it involves several months of weekly visits for appliance adjustment. Although extensive research has been conducted on surgical outcomes after use, little evidence exists pertaining to parental experiences caring for an infant undergoing the nasoalveolar moulding treatment process.

DESIGN

The qualitative design phenomenology was used to best capture parents' lived experiences.

METHODS

Eight mothers and four fathers participated in informal, semi-structured interviews during the months of April-May 2010.

RESULTS

Four themes were identified: (1) You do what you have to do; (2) We weren't left alone in the dark; (3) It's just amazing to see the difference; and (4) It's like nothing ever happened. Findings indicated that despite some difficulties, parents' were dedicated to the treatment process and expressed the benefits exceeded any additional work nasoalveolar moulding required.

CONCLUSION

Multiple recommendations to assist parents with the nasoalveolar moulding treatment process were identified. Improving nasoalveolar moulding education and providing support can substantially improve challenges that are experienced by parents throughout this process - strengthening the importance of their role for successful nasoalveolar moulding outcomes.

Correction of nasal deformity in infants with unilateral cleft lip and palate using multiple digital techniques

Presurgical correction of severe nasal deformities before cheiloplasty is often recommended for infants with cleft lip and palate. This article describes an approach for the computer-aided design and fabrication of a nasal molding stent. A 3-dimensional photogrammetric system was used to obtain the shape information of the nosewing that was then built as the nostril support for the nasal molding stent. The stent was fabricated automatically with a rapid prototyping machine. This technique may be an alternative approach to presurgical nasal molding in the clinic. Moreover, the patient's nasal morphology can be saved as clinical data for future study.

Operative and Immediate Postoperative Outcomes of Using a Latham-Type Dentomaxillary Appliance in Patients with Unilateral Complete Cleft Lip and Palate

Objective

The objective of this study is to examine the operative and immediate postoperative effects of the use of a dentomaxillary appliance (DMA).

Design

Retrospective chart review of 40 treated patients with unilateral complete cleft lip and palate who had a comprehensive set of pre-, peri-, and postoperative records.

Setting

Boston Children's Hospital.

Patients

Forty treated patients with unilateral complete cleft lip and palate.

Interventions

Use of DMA.

Main Outcome Measures

Outcome variables of interest included cleft lip width reduction following use of DMA and odds of having primary gingivoperiostetoplasty (GPP).

Results

The study sample included 40 subjects (31 boys and 9 girls). The average age at the time of DMA insertion was 11 weeks. The average width of the alveolar cleft prior to DMA insertion was 10.77 mm. The mean cleft width reduction was 8.66 mm. Each 1-mm increase in pre-DMA cleft width was associated with a 0.631-mm reduction in cleft width ( P < .001). Thirty-three patients (82.5%) had a GPP procedure. Each 1-mm increase in post-DMA width was associated with a lower odds of having a GPP (odds ratio = 0.32, 95% confidence interval = 0.14–0.77, P = .01).

Conclusions

Post-DMA width was the significant factor associated with the performance of GPP. The use of DMA is associated with a significant reduction in the width of the cleft, and outcomes are predictable without any major adverse events or complications.

Assessment of morbidity following insertion of fixed preoperative orthopedic appliance in infants with complete cleft lip and palate

OBJECTIVE

To examine physiologic and behavioral indicators of pain within the first 24 hours following insertion of the fixed presurgical orthopedic appliance (FPOA) under general anesthesia in infants with unilateral and bilateral complete cleft lip and palate.

METHODS

The study sample included 109 infants who had either a dentomaxillary appliance (DMA) or an elastomeric chain premaxillary retraction (ECPR) appliance. Vital signs and FLACC (Face, Legs, Activity, Cry, Consolability) scores were used to measure the outcomes.

RESULTS

There was an initial postoperative increase in the median heart rate. Heart rate returned to the median baseline level by 8 hours. The median systolic blood pressure increased postoperatively and remained elevated throughout the time of evaluation. The median respiratory rate remained below that at baseline throughout the study period. The highest mean change in FLACC measurements was observed approximately 2 hours postoperatively. By 3 hours postoperatively, the scores decreased.

CONCLUSIONS

Although there was a large individual variability, the FLACC scores became reduced after 3 hours following surgical insertion of the DMA and the ECPR appliance.

CAD presurgical nasoalveolar molding effects on the maxillary morphology in infants with UCLP

OBJECTIVE

This study evaluated the effectiveness of computer-aided design-nasoalveolar molding (CAD-NAM) on maxillary alveolar morphology in infants with unilateral cleft lip and palate (UCLP).

METHODS

15 infants with UCLP treated by CAD-NAM therapy composed the treatment group, and the control group consisted of 15 infants with non-presurgically treated UCLP. The maxillary morphology was analyzed by Rapidform XOR3 software. Differences in all variables pre- and post-CAD-NAM were discussed.

RESULTS

Significant difference was found in arch length, cleft gap, labial frenum deviation, A-X, A'-X, and alveolus height on both sides pre- and post-CAD-NAM.

CONCLUSIONS

This study suggests a trend toward morphological improvement in maxillary alveoli of infants with UCLP treated with CAD-NAM. The CAD-NAM effectively reduced the cleft gap, corrected the maxilla midline, and improved the sagittal length of the maxilla. The alveolar height decreased significantly after the treatment, which indicated that the traction force of the appliance may have obstructive effects on the vertical growth of the alveolar bone.
