Cleft Palate Repair in Robin Sequence following Mandibular Distraction Osteogenesis Compared to Tongue-Lip Adhesion

The Cleft Palate-Craniofacial Journal (2021)

Mychajlo S. Kosyk Anna R. Carlson Zachary D. Zapatero Christopher L. Kalmar Jordan W. Swanson

To evaluate the timing and safety of cleft palate (CP) repair in patients with Robin sequence (RS) treated with mandibular distraction osteogenesis (MDO) or tongue-lip adhesion (TLA) for airway obstruction.Retrospective cohort study.Tertiary Pediatric Hospital during 2004-2020.148 patients with RS underwent MDO, 66 met inclusion by having MDO and followed by palatoplasty. 26 patients with RS underwent TLA, 14 met inclusion by having TLA and followed by palatoplasty.Patient characteristics, hospital/operative details, postoperative complications, and polysomnographic (PSG) data were compared.Groups were well-matched except more patients with syndromes underwent MDO (N = 27, 41%, P ≤ .002). In the MDO and TLA cohorts, mean CP repair age was 12.8 ± 1.9 months and 14.6 ± 1.6 months, respectively (P ≤ .002). Despite the earlier CP repair in the MDO group, there were no differences in peri-operative complication rates after palatoplasty in either group. All sleep respiratory parameters improved after MDO/TLA prior to palatoplasty P ≤ .050. All PSG parameters remained significantly improved after palatoplasty compared to preoperative values, P ≤ .043. Obstructive apnea hypopnea index and Oxygen saturation nadir further improved after palatoplasty within the MDO group, P ≤ .050, while no changes in the TLA group, P ≥ .500.MDO was associated with earlier age at palatoplasty than TLA with a similar perioperative risk profile. In those patients with pre- and post-palatoplasty PSG data, palatoplasty was not associated with a deterioration in PSG parameters, and in fact in the MDO group, PSG data improved.

Influence of Monobloc/Le Fort III Surgery on the Developing Posterior Maxillary Dentition and Its Resultant Effect on Orthognathic Surgery

Plastic & Reconstructive Surgery (2020)

Robin Yang Pasha Shakoori Michael A. Lanni Hyun-Duck Nah Michelle Scott

Background: Timing of frontofacial surgery for the syndromic craniosynostosis as it relates to various surgical risks has not been adequately studied. The purpose of this study was to investigate posterior dental complications of midface advancement in patients with syndromic craniosynostosis undergoing surgery at different ages and the effects on subsequent orthognathic surgery. Methods: A retrospective chart review of patients with syndromic craniosynostosis treated with midface advancement (monobloc or Le Fort III) from 1999 to 2018 was carried out. Patient demographics, records, and imaging studies were reviewed. A subanalysis of those patients who were also treated with orthognathic surgery from 2014 to 2018 with imaging studies available for analysis was also performed. Results: Thirty-seven patients met the inclusion criteria. Sixty-four percent of the patients had radiographic evidence of maxillary molar dental abnormality. Older age at the time of surgery was significantly associated with a lower odds of sustaining dental injury (OR, 0.55; p = 0.034). The odds of damaging second or third maxillary molars was significantly higher with a younger age at the time of surgery ( p = 0.021 and p = 0.034). The odds of sustaining dental injury increased moving posteriorly, showing the risk of abnormal pattern of M3 greater than M2 greater than M1. Advanced age at the time of surgery was significantly associated with decreased odds of dental injury (OR, 0.55; p = 0.034). Conclusions: Damage to the developing permanent maxillary molars may affect orthodontic management, mastication, and potentially maxillary development. Delaying frontofacial surgery until development of the permanent maxillary dentition should be considered if other indications do not mandate earlier intervention.

Severity of Mandibular Dysmorphology in Treacher Collins Syndrome for Stratification of Perioperative Airway Risk

Journal of Craniofacial Surgery (2023)

Carlos E. Barrero Larissa E. Wietlisbach Matthew E. Pontell Lauren K. Salinero Connor S. Wagner

Background: Patients with Treacher Collins syndrome (TCS) and attendant airway dysmorphology may be predisposed to airway complications in the perioperative period. However, limited data correlates severity of mandibular hypoplasia and airway status. This study aims to improve risk stratification for perioperative airway insufficiency in TCS by using a previously proposed mandibular severity index. Methods: Patient demographics, perioperative airway status, difficulty of intubation, and Cormack Lehane grade were collected and compared using a TCS mandibular hypoplasia severity grading scale in patients with TCS treated between 2000 and 2022. Results: Twenty-six patients underwent 222 procedures with institutional mandibular severity gradings as follows: 23% Grade I, 31% Grade II, 39% Grade III, 8% Grade IV. Our severity index was associated with intubation difficulty ( P <0.001) and difficult airway status ( P <0.001), with 72% of difficult airways found in grade III and grade IV patients. Mandibular retrusion and ramal hypoplasia subscores were positively correlated with measures of airway severity ( P <0.001), whereas the gonial angle was negatively correlated ( P <0.001). Age was negatively correlated with difficult visualization for endotracheal intubation ( P =0.02) but had no association with difficult airway status ( P =0.2). Conclusions: This study found a positive correlation between severity of maxillomandibular dysmorphology and perioperative airway difficulty in TCS patients. Our findings suggest that severely affected patients require heightened vigilance throughout life, as difficult airways may not completely resolve with aging. Given the risk of morbidity and mortality associated with airway complications, proper identification and preparation for challenging airways is critical for TCS patients.

Upper thoracic shape in children with pectus excavatum: Impact on lung function

Pediatric Pulmonology (2012)

Gregory J. Redding Wieying Kuo Jonathan O. Swanson Grace S. Phillips Julia Emerson

Pectus excavatum (PE) can present with respiratory complaints in childhood. However severity of the PE, measured by the Pectus Severity Index (PSI), correlates only modestly with reduced vital capacity (VC). We hypothesized that another upper thoracic feature, a pectus gracilis (PG) or slender chest, co-exists with PE, and impacts lung function.We developed the Pectus Gracilis Index (PGI) based on the chest width to depth ratio at the gladiolar-manubrial sternal junction on computerized tomographic (CT) scans, and measured PGI among 316 control children 10-20 years old. PG was defined by PGI values >2 z-scores above the mean normal value. We determined the prevalence of PG in 97 children with PE and correlated PGI and PSI with VC among the 86 that performed spirometry.The mean and upper limit of normal for PGI averaged 2.73 and 3.55, respectively for control children. The prevalences of a PG among controls and children with PEs were 3.2% and 59%, respectively (OR = 45, P < 0.00001). Among the children with PEs, the PGI, and PSI correlated with one another (r = 0.77, P < 0.001). Both PSI and PGI significantly correlated inversely with VC. (r = -0.34, P < 0.001 and r = -0.38, P < 0.001, respectively). Importantly, PGI correlated with VC after adjusting for PSI among children with PE. (r = 0.20, P < 0.03).The upper thoracic feature of a PG is common among children with PE and contributes to reductions in VC. Assessment of the thorax, using the PGI, may improve the structure-function correlations previously described for children with PE.

Correlation between degree of sagittal suture fusion and surrogates of elevated intracranial pressure in sagittal craniosynostosis

Journal of Neurosurgery Pediatrics (2023)

Dillan F. Villavisanis Jessica D. Blum Carlos E. Barrero Christopher L. Kalmar Natalie M. Plana

OBJECTIVE Sagittal craniosynostosis constricts transverse skull growth, with possible neurocognitive sequelae. While the degree of sagittal suture fusion has been shown to influence the degree of dysmorphology, it is unknown if it impacts functional findings, including elevated intracranial pressure (ICP). The purpose of this study was to determine associations between the degree of sagittal suture fusion and optical coherence tomography (OCT) surrogates suggestive of increased ICP in patients with nonsyndromic sagittal craniosynostosis. METHODS Three-dimensional CT head images of patients with sagittal craniosynostosis were analyzed in Materialise Mimics and parietal bones were manually isolated to determine the percentage fusion of the sagittal suture. Retinal OCT was performed prior to the cranial vault procedure with analysis for thresholds that correlate with elevated ICP. The degree of sagittal suture fusion was compared with OCT retinal parameter measurements using Mann-Whitney U-tests, Spearman’s correlations, and multivariate logistic regression models controlled for age. RESULTS Forty patients (31 males) with nonsyndromic sagittal craniosynostosis at a mean (± SD) age of 3.4 ± 0.4 months were included in this study. OCT surrogates of elevated ICP (maximal retinal nerve fiber layer [RNFL] thickness and maximal anterior projection [MAP]) were not associated with total sagittal suture fusion (p > 0.05). Maximal RNFL thickness was positively associated with increased percentage of posterior one-half (rho = 0.410, p = 0.022) and posterior one-third (rho = 0.417, p = 0.020) sagittal suture fusion. MAP was also positively associated with increased percentage of posterior one-half (rho = 0.596, p < 0.001) and posterior one-third (rho = 0.599, p < 0.001) sagittal suture fusion. Multivariate logistic regression models revealed increased percentage of posterior one-half (p = 0.048) and posterior one-third (p = 0.039) sagittal suture fusion predicted ICP > 20 mm Hg. CONCLUSIONS Increased percentage fusion of the posterior sagittal suture, but not total suture, was positively associated with retinal changes indicative of increased ICP. These findings suggest suture fusion leading to increased ICP may be region specific.

The Essential Anatomical Subunit Approximation Unilateral Cleft Lip Repair

Plastic & Reconstructive Surgery (2016)

David K. Chong Jordan W. Swanson

The anatomical subunit approximation cleft lip repair advantageously achieves a balanced lip contour, with the line of repair hidden along seams of aesthetic subunits. Dr. David Fisher's original description of the repair reflects the considerable thought that went into the evolution of his design. As his technique has gained acceptance in the intervening 10 years, the authors note several key principles embodied in it that represent a shift in the cleft lip repair paradigm. The authors believe understanding these principles is important to mastery of the anatomical subunit technique, and facilitate its teaching. First, design a plan that adheres to anatomical subunits and perform measurements precisely. Second, identify and adequately release each cleft tissue layer from the lip and nose to enable restoration of balance. Third, drive surgical approximation through inset of the lateral muscle into the superiorly backcut medial orbicularis muscle, followed by skin closure with inferior triangle interposition above the white roll. In this article, the authors present essential components of the technique, and identify several principles that enable its successful execution.

A Sustainable Model for Patient follow-up following an International Cleft Mission

The Cleft Palate-Craniofacial Journal (2017)

Ari M. Wes Nadine Paul Patrick A. Gerety Nancy Folsom Jordan W. Swanson

Patient follow-up after cleft missions is imperative if we are to critically assess the quality of care provided in these settings. The adoption of mobile telephones among disadvantaged families abroad may enable such an undertaking in a cost-effective manner. This project aimed to assess the efficacy of cellular phone-based follow-up in a developing country following a cleft mission to Thailand.Changing Children's Lives Inc. performed a cleft surgical mission to Udon Thani, Thailand, in January 2013. Telephone numbers collected at that time were used to survey the patients or their parents 1.5 years postoperatively.Of the 56 patients who underwent cleft lip and/or palate surgery during the mission, more than 50% ( n = 30, 54%) were reachable by telephone; all chose to participate in the study. The cost for families was U.S. $124.92 (56.15); 26 families (87%) believed their money was well spent. Follow-up care was received by 22 (73%) patients, and all but one family ( n = 29, 97%) felt that their child received all of the medical care and support required. All families ( N = 30) would recommend similar cleft care to a friend. Of the patients younger than 18 years of age ( n = 24, 80%), 20 (80%) families found their child more comfortable interacting with peers, more comfortable interacting with adults, and more confident postoperatively.In one month, a survey response rate of more than 50% was obtained by leveraging the increased adoption of mobile phones in rural settings. Nearly all patients/families treated during the cleft mission were satisfied with the care that they received.

Characterizing Interventions and Family Assistance of a Nurse Navigation Program in Orofacial Cleft Care

The Cleft Palate-Craniofacial Journal (2023)

Connor S. Wagner Carlos E. Barrero Satvika L Kumar Matthew E. Pontell Lauren K. Salinero

Objective Characterize the interventions and assistance employed by a cleft nurse navigator (CNN) which have mediated improvement in care equity at our institution. Design Retrospective study. Setting Academic tertiary care center. Patients, Participants Patients presenting with cleft lip and/or cleft palate presenting between August 2020 and August 2021 with exclusions for syndromic diagnosis, Pierre-Robin sequence, late (> 6 months) presentation, and prior cleft surgery at outside institutions. Interventions Multidisciplinary cleft nurse navigator program Main Outcome Measure(s) Family interactions with the CNN by phone, text, and email across the first year of life including feeding support, nasoalveolar molding (NAM) assistance, appointment scheduling, financial assistance, addressing perioperative concerns, and facilitating physician consults. Patient weight and surgical timing were also recorded. Results Sixty-nine patients were included with a total of 639 interactions between the CNN and families. Scheduling support (30%), addressing perioperative concerns (22%), and feeding support (20%) were the most common interactions. Feeding support and NAM assistance were heavily distributed in the first 3 months of life compared to after 3 months ( P < .001). Median age at first contact was 1 week (range: 22 weeks gestation-14 weeks). There was no difference in the proportion of families receiving feeding support, NAM assistance, or scheduling assistance based on insurance status or race ( P > .05 for all). Conclusions Scheduling assistance, addressing perioperative concerns, and feeding support are the predominant methods by which the CNN interacts with and assists families of patients with cleft conditions. CNN service distribution is largely equitable between demographic groups.
