Abstract
OBJECTIVE To present the design and methodology for an actively enrolling comparative effectiveness study of revision palatoplasty versus pharyngoplasty for the treatment of velopharyngeal insufficiency (VPI). DESIGN Prospective observational multicenter study. SETTING Twelve hospitals across the United States and Canada. PARTICIPANTS Individuals who are 3-23 years of age with a history of repaired cleft palate and a diagnosis of VPI, with a total enrollment target of 528 participants. INTERVENTIONS Revision palatoplasty and pharyngoplasty (either pharyngeal flap or sphincter pharyngoplasty), as selected for each participant by their treatment team. MAIN OUTCOME MEASURE(S) The primary outcome is resolution of hypernasality, defined as the absence of consistent hypernasality as determined by blinded perceptual assessment of a standard speech sample recorded twelve months after surgery. The secondary outcome is incidence of new onset obstructive sleep apnea. Statistical analyses will use propensity score matching to control for demographics, medical history, preoperative severity of hypernasality, and preoperative imaging findings. RESULTS Study recruitment began February 2021. As of September 2022, 148 participants are enrolled, and 78 have undergone VPI surgery. Enrollment is projected to continue into 2025. Collection of postoperative evaluations should be completed by the end of 2026, with dissemination of results soon thereafter. CONCLUSIONS Patients with VPI following cleft palate repair are being actively enrolled at sites across the US and Canada into a prospective observational study evaluating surgical outcomes. This study will be the largest and most comprehensive study of VPI surgery outcomes to date.

Abstract
Traditional imaging modalities used to assess velopharyngeal insufficiency (VPI) do not allow for direct visualization of underlying velopharyngeal (VP) structures and musculature which could impact surgical planning. This limitation can be overcome via structural magnetic resonance imaging (MRI), the only current imaging tool that provides direct visualization of salient VP structures. MRI has been used extensively in research; however, it has had limited clinical use. Factors that restrict clinical use of VP MRI include limited access to optimized VP MRI protocols and uncertainty regarding how to interpret VP MRI findings. The purpose of this paper is to outline a framework for establishing a novel VP MRI scan protocol and to detail the process of interpreting scans of the velopharynx at rest and during speech tasks. Additionally, this paper includes common scan parameters needed to allow for visualization of velopharynx and techniques for the elicitation of speech during scans.

Abstract
The anatomic subunit approximation approach to unilateral cleft lip repair was developed over 20 years ago. While the underlying principles of the repair are unchanged, its description has been simplified, additional landmarks and creases have been added, and objective analysis of perioperative changes have provided better clarity regarding goals and desired alterations. We review recent insights regarding the deformity; describe the repair in a simplified manner; and link a stepwise approach to foundation-based primary rhinoplasty as a part of the avenue to creating nasolabial balance and harmony.

Selective nerve transfers to restore shoulder abduction and flexion in acute flaccid myelitis: A case report. Microsurgery 2024; 44:e31104. [PMID: 37646277 DOI: 10.1002/micr.31104] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2022] [Revised: 07/19/2023] [Accepted: 08/16/2023] [Indexed: 09/01/2023]
Abstract
Acute flaccid myelitis (AFM) is a polio-like condition predominantly affecting children that is characterized by acute-onset, asymmetric flaccid paralysis, often preceded by a prodromal fever or viral illness. With prompt diagnosis and early surgical referral, nerve transfers may be performed to improve function. Highly selective nerve transfers are ideal to preserve existing functions while targeting specific deficits. In this report, we present a case of a double fascicular nerve transfer of median and ulnar nerve fascicles to the axillary nerve, combined with selective transfer of the spinal accessory nerve to the supraspinatus branch of the suprascapular nerve, performed for a 5-year-old girl who developed AFM after an upper respiratory infection. Six months after the onset of the patient's symptoms, the patient had continued weakness of shoulder flexion and abduction, atrophy of the deltoid, and supraspinatus muscles, though needle electromyography revealed a functioning infraspinatus muscle. The patient had no post-operative complications and at 2 years of postoperative follow up achieved shoulder abduction and flexion Active Movement Scale scores of 7/7 compared to preoperative scores of 2/7, with no loss of function in the donor nerve domains. The patient showed active shoulder abduction against gravity to 90° from 30° preoperatively and shoulder flexion to 180° from 15° preoperatively. This case report shows that highly selective nerve transfers may preserve existing functions while targeting specific deficits. A double fascicular transfer from the median and ulnar nerves to axillary nerve may provide abundant axons for functional recovery.

Abstract
OBJECTIVE Objective measurement of pre-operative severity is important to optimize evidence-based practices given that the wide spectrum of presentation likely influences outcomes. The purpose of this study was to determine the correlation of objective measures of form with a subjective standard of cleft severity. DESIGN 3D images were ranked according to severity of nasal deformity by 7 cleft surgeons so that the mean rank could be used as the severity standard. PATIENTS 45 patients with unilateral cleft lip and 5 normal control subjects. INTERVENTIONS Each image was assessed using traditional anthropometric analysis, 3D landmark displacements, and shape-based analysis to produce 81 indices for each subject. MAIN OUTCOME The correlation of objective measurements with the clinical severity standard. RESULTS Lateral deviation of subnasale from midline was the best predictor of severity (0.86). Other strongly-correlated anthropometric measurements included columellar angle, nostril width ratio, and lateral lip height ratio (0.72, 0.80, 0.79). Almost all shape-based measurements had tight correlation with the severity standard, however, dorsum deviation and point difference nasolabial symmetry were the most predictive (0.84, 0.82). CONCLUSIONS Quantitative measures of severity transcend cleft type and can be used to grade clinical severity. Lateral deviation of subnasale was the best measure of severity and may be used as a surrogate of uncoupled premaxillary growth; it should be recorded as an index of pre-operative severity with every cleft lip repair. The correlation of other measures evaluated clarify treatment priorities and could potentially be used to grade outcomes.

Abstract
OBJECTIVE Surgical treatment of velopharyngeal insufficiency (VPI) includes a wide array of procedures. The purpose of this study was to develop a classification for VPI procedures and to describe variations in how they are performed.Design/participants/setting/outcomes: We completed an in-depth review of the literature to develop a preliminary schema that encompassed existing VPI procedures. Forty-one cleft surgeons from twelve hospitals across the USA and Canada reviewed the schema and either confirmed that it encompassed all VPI procedures they performed or requested additions. Two surgeons then observed the conduct of the procedures by surgeons at each hospital. Standardized reports were completed with each visit to further explore the literature, refine the schema, and delineate the common and unique aspects of each surgeon's technique. RESULTS Procedures were divided into three groups: palate-based surgery; pharynx-based surgery; and augmentation. Palate-based operations included straight line mucosal incision with intravelar veloplasty, double-opposing Z-plasty, and palate lengthening with buccal myomucosal flaps. Many surgeons blended maneuvers from these three techniques, so a more descriptive schema was developed classifying the maneuvers employed on the oral mucosa, nasal mucosa, and muscle. Pharynx-based surgery included pharyngeal flap and sphincter pharyngoplasty, with variations in design for each. Augmentation procedures included palate and posterior wall augmentation. CONCLUSIONS A comprehensive schema for VPI procedures was developed incorporating intentional adaptations in technique. There was substantial variation amongst surgeons in how each procedure was performed. The schema may enable more specific evaluations of surgical outcomes and exploration of the mechanisms through which these procedures improve speech.

Abstract
Neonatal brachial plexus palsies (NBPP) occur in 1.74 per 1000 live births with 20% to 30% having persistent deficits. Dysfunction can range from mild to severe and is correlated with the number of nerves involved and the degree of injury. In addition, there are several comorbidities and musculoskeletal sequelae that directly impact the overall functional development. This review addresses the nonsurgical and surgical management options and provides guidance for pediatricians on monitoring and when to refer for specialty care.

Revisiting the unrepaired unilateral cleft lip and nasal deformity using 3D surface image analysis: A data-driven model and its implications. J Plast Reconstr Aesthet Surg 2021; 74:2694-2704. [PMID: 33941472 DOI: 10.1016/j.bjps.2021.03.026] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2019] [Revised: 02/04/2021] [Accepted: 03/11/2021] [Indexed: 11/18/2022]
Abstract
BACKGROUND Current descriptions of the unilateral cleft lip and nasal deformity (uCLND) are based upon limited sample sets and subjective observations. While those descriptions are inconsistent and contradictory, theoretical models, including Hogan's "tilted tripod" and Fisher's "nasal arch forms", have never been tested. Given that favorable outcomes of treatment remain elusive, detailed study of the deformity is critical in devising better treatments. The purpose of this study was to develop a data-driven three-dimensional (3D) model of uCLND that spans the spectrum of presentation and involves a pervasive underlying mechanism. METHODS We studied 3D images of 100 infants with unrepaired cleft lip at 6 months of age. Objective assessment included the landmark positions, anthropometric dimensions, and shape-based measures. Cleft severity was stratified by the lateral displacement of subnasale, so that a model could be developed using linear regression. RESULTS With progressive deviation of subnasale, the non-cleft alar base moved lateral, the cleft alar base was left posterior, and the nasal dorsum followed the caudal septum (deviating towards the non-cleft side). The "twist" resulted in opposing cleft alar dome collapse, non-cleft alar ring constriction (the non-cleft nasal sill narrowed, lateral genu rose, and alar-cheek junction became more acute), and displacement of the philtrum from midline. CONCLUSIONS Our study not only supports theoretical models of uCLND but also clarifies vectors of change and reveals significant non-cleft side alterations. On the basis of our findings, the objectives of treatment should involve centralization of the columella and philtrum and rebalancing the nose by untwisting the orthogonal displacement of the alar bases.

Partial tibial nerve transfer for foot drop from deep peroneal palsy: Lessons from three pediatric cases. Microsurgery 2020; 42:71-75.

Abstract
Peroneal nerve palsy with resultant foot drop has significant impacts on gait and quality of life. Traditional management includes ankle-foot-orthosis, tendon transfer, and arthrodesis-each with certain disadvantages. While nerve transfers for peroneal nerve injury have been reported in adults, with variable results, they have not been described in the pediatric population. We report the use of partial tibial nerve transfer for foot drop from deep peroneal nerve palsy in three pediatric patients. The first sustained a partial common peroneal nerve laceration and underwent transfer of a single tibial nerve branch to deep peroneal nerve 7 months after injury. Robust extensor hallucis longus and extensor digitorum longus reinnervation was obtained without satisfactory tibialis anterior function. The next patient sustained a thigh laceration with partial sciatic nerve injury and underwent transfer of two tibial nerve branches directly to the tibialis anterior component of deep peroneal nerve 9 months after injury. The final patient sustained a blast injury to the posterior knee and similarly underwent a double fascicular transfer directly to tibialis anterior 4 months after injury. The latter two patients obtained sufficient strength (MRC 4-5) at 1 year to discontinue orthosis. In all patients, we used flexor hallucis longus and/or flexor digitorum longus branches as donors without postoperative loss of toe flexion. Overall, our experience suggests that early double fascicular transfer to an isolated tibialis anterior target, combined with decompression, could produce robust innervation. Further study and collaboration are needed to devise new ways to treat lower extremity nerve palsies.

Abstract
OBJECTIVE To provide an inventory of oronasal fistula repair techniques alongside expert commentary on which techniques are appropriate for each fistula type. DESIGN A 4-stage approach was used to develop a consensus on surgical techniques available for fistula repair: (1) in-person discussion of oronasal fistula cases among cleft surgeons, (2) development of a schema for fistula management using transcripts of the in-person case discussion, (3) evaluation of the preliminary schema via a web-based survey of additional cleft surgeons, and (4) revision of the management schema using survey responses. PARTICIPANTS Six cleft surgeons participated in the in-person case discussion. Eleven additional surgeons participated in the web-based survey. Participants had diverse training experiences, having completed residency and fellowship at 20 different hospitals. RESULTS A schema for fistula management was developed, organized by fistula location. The schema catalogues all viable approaches for each location. For fistulae involving the soft palate, the schema stresses the importance of evaluating for velopharyngeal insufficiency (VPI) and incorporating VPI management into fistula repair. For fistulae involving the hard palate, the schema separately enumerates the techniques available for nasal lining repair and for oral lining repair in each region. The schema also catalogues the diversity of approaches to lingual- and labioalveolar fistula, including variation in timing, orthodontic preparation, and simultaneous alveolar bone grafting. CONCLUSIONS This study employed consensus methods to create a comprehensive inventory of available fistula repair techniques and to identify preferential techniques among a diverse group of surgeons.

Abstract
BACKGROUND Shoulder release and tendon transfer is frequently performed to address persistent weakness from neonatal brachial plexus palsy. Although postoperative improvements in motion are well described, associated deficits are poorly documented, and functional assessments are lacking. Loss of ability to reach midline can occur with surgery and may result in impairment. The purpose of this study was to comprehensively assess the gains, losses, functional changes, and patient-reported outcome associated with the authors' surgical approach. METHODS Consecutive patients undergoing surgery with 2-year follow-up were included (n = 30). Prospectively recorded assessments by therapists were reviewed. Changes were assessed by t test and Wilcoxon rank sum (p < 0.05). RESULTS Active external rotation and abduction improved and internal rotation diminished. Aggregate modified Mallet score increased with improvements in all subscales, except that hand to spine was unchanged and hand to belly decreased. Functional assessment using the Brachial Plexus Outcome Measure revealed an increase of aggregate score, with no decline in any subscales. Improvements were in hand to back of head, forward overhead reach, holds plate with palm up, opening large container, and strings bead. Aggregate patient self-report of appearance and function increased (from 18 to 23). Loss of ability to reach midline occurred in three patients (10 percent) who had extended Erb or total palsy and preoperative limitations of internal rotation. CONCLUSIONS Secondary reconstruction rebalances shoulder motion by increasing external rotation and abduction and reducing internal rotation. In this study, a conservative surgical approach results in overall improvement in task-based abilities and self-reported outcomes and preservation of internal rotation within a functional range. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, IV.

Abstract
Transverse clefts of the oral cavity have significant impacts on both appearance and function. Many methods of repair have been described, but there is no consensus on optimal approach. In addition, dissatisfaction with scars, distortion of appearance, and recurrent deformity have led to complex surgical designs that are difficult to understand and reproduce. We describe a simple approach to repair that is based upon anatomic approximation of lip components and accurate repair of the muscle. Twenty patients underwent repair by the senior author, who devised the approach, and the corresponding author, who adopted it. Eight (62%) patients had right-sided clefts, three (23%) patients had left-sided clefts, and two (15%) patients had bilateral clefts. One patient had an associated branchial cleft remnant, two patients had multiple branchial cleft remnants and tragus deformities, one patient had craniofacial microsomia with microtia, and one patient had a contralateral Tessier 1 cleft. Mean age of the patients at repair was 23 months. All patients achieved normal oral competence, have favorable scars and commissure appearance, and have had no recurrent deformity. None of the patients have required revision. The described surgical approach is reproducible, easy to understand, and can produce favorable outcomes.

Abstract
OBJECTIVE Oronasal fistula is an important complication of cleft palate repair that is frequently used to evaluate surgical quality, yet reliability of fistula classification has never been examined. The objective of this study was to determine the reliability of oronasal fistula classification both within individual surgeons and between multiple surgeons. DESIGN Using intraoral photographs of children with repaired cleft palate, surgeons rated the location of palatal fistulae using the Pittsburgh Fistula Classification System. Intrarater and interrater reliability scores were calculated for each region of the palate. PARTICIPANTS Eight cleft surgeons rated photographs obtained from 29 children. RESULTS Within individual surgeons reliability for each region of the Pittsburgh classification ranged from moderate to almost perfect (κ = .60-.96). By contrast, reliability between surgeons was lower, ranging from fair to substantial (κ = .23-.70). Between-surgeon reliability was lowest for the junction of the soft and hard palates (κ = .23). Within-surgeon and between-surgeon reliability were almost perfect for the more general classification of fistula in the secondary palate (κ = .95 and κ = .83, respectively). CONCLUSIONS This is the first reliability study of fistula classification. We show that the Pittsburgh Fistula Classification System is reliable when used by an individual surgeon, but less reliable when used among multiple surgeons. Comparisons of fistula occurrence among surgeons may be subject to less bias if they use the more general classification of "presence or absence of fistula of the secondary palate" rather than the Pittsburgh Fistula Classification System.

Abstract
OBJECTIVE This study compares speech and surgical outcomes in internationally adopted and nonadopted patients undergoing cleft palate repair, and examines the influence of age at initial palatoplasty. DESIGN Retrospective cohort study setting: Tertiary Care Children's Hospital. PATIENTS 70 international adoptees and 211 nonadoptees with Veau type III and IV clefts (without associated syndrome) repaired at our institution. OUTCOME MEASURES Outcomes included VPI, compensatory misarticulations, intelligibility, nasal air emission, oronasal fistula, and secondary speech surgery. Speech evaluations completed near 5 years of age were gathered from a prospectively collected database. RESULTS Adoptees underwent palatoplasty 5.2 months after arrival, a mean of 10.4 months later than nonadoptees. Adoptees were significantly more likely to develop moderate/severe VPI and trended toward more frequent need for secondary speech surgery. Oronasal fistula occurred at similar rates. Increased age at initial palatoplasty was a significant predictor of moderate to severe VPI, and need for secondary speech surgery. CONCLUSIONS International adoptees undergo palatoplasty 10.4 months later than nonadoptees and are significantly more likely to develop moderate/severe VPI, with a trend toward increased secondary speech surgery. An association between treatment delay and moderate/severe VPI and secondary speech surgery has been demonstrated. While a causal relationship between delayed repair and inferior outcomes in international adoptees has not been proven, this data suggests that surgical intervention upon unrepaired cleft palates soon after adoption may be beneficial. The opportunity for a change in practice exists, as half of the 10.4-month relative delay in palate repair occurs postadoption.

Abstract
BACKGROUND Optimization of treatment of the unilateral cleft lip nasal deformity (uCLND) is hampered by lack of objective means to assess initial severity and changes produced by treatment and growth. The purpose of this study was to develop automated 3D image analysis specific to the uCLND; assess the correlation of these measures to esthetic appraisal; measure changes that occur with treatment and differences amongst cleft types. METHODS Dorsum Deviation, Tip-Alar Volume Ratio, Alar-Cheek Definition, and Columellar Angle were assessed using computer-vision techniques. Subjects included infants before and after primary cleft lip repair (N = 50) and children aged 8-10 years with previous cleft lip (N = 50). Two expert surgeons ranked subjects according to esthetic nose appearance. RESULTS Computer-based measurements strongly correlated with rankings of infants pre-repair (r = 0.8, 0.75, 0.41 and 0.54 for Dorsum Deviation, Tip-Alar Volume Ratio, Alar-Cheek Definition, and Columellar Angle, p < 0.01) while all measurements except Alar-Cheek Definition correlated moderately with rankings of older children post-repair (r ∼ 0.35, p < 0.01). Measurements were worse with greater severity of cleft type but improved following initial repair. Abnormal Dorsum Deviation and Columellar Angle persisted after surgery and were more severe with greater cleft type. CONCLUSIONS Four fully-automated measures were developed that are clinically relevant, agree with expert evaluations and can be followed through initial surgery and in older children. Computer vision analysis techniques can quantify the nasal deformity at different stages, offering efficient and standardized tools for large studies and data-driven conclusions.

Abstract
PURPOSE To evaluate the presence and degree of glenohumeral dysplasia (GHD) in infants undergoing surgical exploration for neonatal brachial plexus palsy (NBPP) and to identify potential predictive factors of early maladaptive shoulder morphology. METHODS We included all consecutive patients with NBPP who underwent surgical exploration of their brachial plexus and who had a preoperative magnetic resonance imaging scan at our institution over a 3-year period. Demographic, therapy, and surgical data were collected. Imaging was reviewed for glenoid morphology, glenoid version, percent humeral head anterior to the scapula, and alpha angle. RESULTS Of 116 infants who presented to our institution during this 3-year period, 19 (16%) underwent surgical exploration and were included in the study. Median age at the time of the scan was 16 weeks (interquartile range, 14-46 weeks). Fourteen of 19 (74%) had GHD of Waters class 2 or increased malformation. Babies who had more severe palsies underwent earlier surgery and had less severe GHD at the time of surgery than did those with less severe palsies who had surgery later. Less severe GHD was associated with more severe palsies, as indicated by Narakas classification and number of root avulsions. Active external rotation was almost universally absent whereas other shoulder movements were present to varying degrees. More severe GHD was associated with greater total shoulder active range of motion and greater pectoralis major muscle mass. CONCLUSIONS Glenohumeral dysplasia occurs often and early in NBPP and may occur in the absence of restricted range of motion. Predictors include increasing age and factors related to muscular imbalance. As such, GHD likely affects the functional outcome that may be achieved with reinnervation, and early screening may improve outcomes. TYPE OF STUDY/LEVEL OF EVIDENCE Prognostic IV.

Abstract
Although the early benefits of endoscopic carpal tunnel release have been demonstrated, there is great controversy regarding the risks and safety of the technique. The present study reports early major complications in a series of 1278 consecutive cases performed by a single surgeon over a seven-year period. All procedures were performed under local anaesthesia on an outpatient basis using the Agee single portal technique. Mean follow-up was three months. No vascular, tendon or permanent nerve injuries were documented. Recurrent or persistent symptoms occurred in 7% of patients for which 20 of 89 underwent subsequent open carpal tunnel release. No nerve injuries were found on re-exploration. Other complications were consistent with previously reported incidences. This is the largest reported case series by a single surgeon and represents an accumulation of surgical experience at the upper end of the learning curve. Endoscopic carpal tunnel release is a safe procedure in this experienced single surgeon series.

Abstract
Orofacial clefting is a common birth defect with wide phenotypic variability. Many systems have been developed to classify cleft patterns to facilitate diagnosis, management, surgical treatment, and research. In this review, we examine the rationale for different existing classification schemes and determine their inter-relationships, as well as strengths and deficiencies for subclassification of clefts of the lip. The various systems differ in how they describe and define attributes of cleft lip (CL) phenotypes. Application and analysis of the CL classifications reveal discrepancies that may result in errors when comparing studies that use different systems. These inconsistencies in terminology, variable levels of subclassification, and ambiguity in some descriptions may confound analyses and impede further research aimed at understanding the genetics and etiology of clefts, development of effective treatment options for patients, as well as cross-institutional comparisons of outcome measures. Identification and reconciliation of discrepancies among existing systems is the first step toward creating a common standard to allow for a more explicit interpretation that will ultimately lead to a better understanding of the causes and manifestations of phenotypic variations in clefting.

Abstract
Dynamic left ventricular outflow obstruction is associated with structural findings of asymmetric septal hypertrophy (less commonly concentric left ventricular hypertrophy) and systolic anterior motion of the anterior mitral valve leaflet. A patient who did not have this usual substrate for outflow obstruction presented with an acute anterior wall myocardial infarction complicated by congestive heart failure and cardiogenic shock. When an intra-aortic balloon pump was placed, the patient rapidly deteriorated and a dynamic outflow gradient was detected.
