Lacrimal Obstruction in Craniosynostosis: Anatomical and Genetic Risk Factors.

PURPOSE: To investigate whether patients with craniosynostosis exhibit higher rates of nasolacrimal duct obstruction (NLDO) and to explore potential risk factors. METHODS: Retrospective review including all craniosynostosis patients treated at both the Divisions of Ophthalmology and Plastic, Reconstructive, and Oral Surgery at The Children's Hospital of Philadelphia between 2009 and 2020 was conducted. Synostosis characteristics, lacrimal disorders, and genetic data were collected. Main outcome measures were the rate of NLDO and associations with anatomical and syndromic/genetic risk factors. RESULTS: The total of 767 participants had a mean age of 2.8 ± 3.8 years, 465 (60.6%) were males, 485 (63.2%) had no syndromic association; 631 (82.3%) had one major suture involved, 128 (17%) had involvement of 2 to 4 major sutures, and 429 (55.9%) underwent craniofacial surgery. Forty-eight (6.2%) patients had NLDO, which more prevalent in the genetic/syndromic group (11.0% vs. 3.5%, respectively, p < 0.001), with the highest prevalence observed in patients with Apert syndrome (n = 4, 30.8%). The genetic variants most associated with NLDO were EFNB1 (n = 1, 100%) and FGFR2 (n = 6, 19.4%). There was no association between NLDO and the number or types of sutures involved or a history of craniofacial surgery. CONCLUSIONS: Nasolacrimal duct obstruction is more common in patients with craniosynostosis compared to the general population. Having a putative syndrome or a putative genetic variant and female sex were risk factors for NLDO. Ophthalmic evaluations for all craniosynostosis patients and careful assessments of any symptoms of tearing are recommended.

Timing of Autologous Tissue Breast Reconstruction Does Not Affect Free Flap Failure.

ABSTRACT: This study aimed to determine whether there is a difference in free flap failure based on the decision to undergo immediate versus delayed autologous tissue breast reconstruction after mastectomy. The National Surgical Quality Improvement Program database was queried for breast free flap procedures performed between 2015 and 2020. This study demonstrates that the decision to undergo immediate versus delayed autologous tissue breast reconstruction does not have a significant association with free flap failure. This remains true regardless of whether patients undergo unilateral mastectomy with reconstruction or whether patients choose to also undergo contralateral prophylactic mastectomy with reconstruction.

Surgical Complexity and Physician Workload in Craniofacial Surgery: Do RVUs Need to be Adjusted?

RVU valuations need to be revisited regularly as procedure complexity and patient care pathways continue to evolve. The NSQIP-P database was queried for craniofacial procedures performed in North America between 2012 and 2019. Multivariate regression was performed to determine correlation coefficients of perioperative variables deemed to reflect procedure severity, including procedure duration, blood transfusion, length of stay, serious adverse events, related readmission, and related reoperation. CPT 21159 Le Fort III with forehead advancement remains the craniofacial procedure with the highest RVUs using our model at 33.93 units. The most underestimated procedure is CPT 42235 Repair of anterior palate, including vomer flap, with a suggested change of +8.27 units, which is a 194% increase from current compensation. Adjusted RVUs based on quantitative and nationally representative perioperative variables that reflect procedure severity might be a better alternative for procedure valuation over current survey methods to determine appropriate insurance compensation.

Complete Extensive Heterotopic Ossification of the Entire Free Fibula Flap Vascular Pedicle in Maxillary Reconstruction.

INTRODUCTION: Heterotopic ossification is a pathologic extra-skeletal bone formation as a form of aberrant repair process with acquired or genetic etiologies. In plastic surgery, it has been well-described in the burn and trauma patients. Rarely, it can happen along the vascular pedicle of free tissue transfer, and when it happens, it is most commonly in head and neck reconstruction. CASE PRESENTATION: Here we present a case of complete extensive heterotopic ossification of the entire vascular pedicle from the anastomosis to the bone in an osteocutaneous free fibula flap (FFF). The fibula was used as a 2-segment reconstruction for a maxillary defect resulting from a self-inflicted gunshot wound. The skin paddle was used to reconstruct the anterior palatal defect. DISCUSSION: Heterotopic ossification of the FFF vascular pedicle is most reported in the head and neck reconstruction cases. It is rare, but when it happens, it occurs earlier, more commonly, and more extensively in cases of maxillary reconstruction than in cases of mandibular reconstruction. Flap loss due to this sequela has not been reported, and surgical debridement is indicated only when symptomatic. CONCLUSION: Heterotopic ossification of an FFF vascular pedicle is a rare but well-described entity. The periosteal bone formation capacity preservation after revascularization of the flap is thought to be one of the major etiologies of this phenomenon. Hence, some have suggested a modification in the harvesting technique of the FFF that could mitigate return to the operating room, especially when it is for maxillary reconstruction in the trauma patient. Keywords: Keywords: free fibula flap, heterotopic ossification, maxillary reconstruction, mandibular reconstruction.

Autologous Cranioplasty Using a Dental SafeScraper Device.

SUMMARY: Conventional methods to reconstruct cortical bone defects introduced by pediatric cranial vault remodeling (CVR) procedures have shortcomings. Use of bone burr shavings as graft material leads to variable ossification, and harvesting split-thickness cortical grafts is time-intensive and often not possible in thin infant calvaria. Since 2013, the authors' team has used the SafeScraper, originally developed as a dental instrument, to harvest cortical and cancellous bone grafts during CVR. The authors assessed the effectiveness of this technique by analyzing postoperative ossification using computed tomography scans of 52 patients, comparing cohorts treated with the SafeScraper versus those who received conventional methods of cranioplasty during fronto-orbital advancement. The SafeScraper cohort had a greater reduction in total surface area of all defects (-83.1% ± 14.9 versus -68.9% ± 29.8; P = 0.034), demonstrating a greater and more consistent degree of cranial defect ossification compared with conventional methods of cranioplasty, suggesting potential adaptability of this tool. This is the first study that describes the technique and efficacy of the SafeScraper in reducing cranial defects in CVR. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Bilateral Buccal Flap Revision Palatoplasty to Correct Velopharyngeal Dysfunction: Perceptual Speech, Acoustic, and Aerodynamic Outcomes.

BACKGROUND: The purpose of this study was to analyze perceptual, acoustic, and aerodynamic changes in speech and velopharyngeal function after bilateral buccal flap revision palatoplasty (BBFRP) in patients with repaired cleft palate. METHODS: Ten consecutive patients ages 4 to 18 years with velopharyngeal dysfunction treated with BBFRP by a single surgeon were evaluated. Using a visual analog scale, nine blinded speech-language pathologists independently rated hypernasality, hyponasality, audible nasal emission, and speech acceptability. Measurements of the acoustic speech signal were used to quantify changes in hypernasality and nasal emission. The pressure flow technique was used to determine changes in velopharyngeal gap size. RESULTS: Complete records were available for eight patients. After surgery, hypernasality decreased ( P < 0.001) and speech acceptability increased ( P < 0.001) significantly. Audible nasal emission was significantly reduced ( P < 0.001). Postoperative acoustic measures showed a reduction of nasal emission and nasalization. Velopharyngeal gap size significantly decreased after BBFRP ( P < 0.001), correlating with lower visual analog scale ratings of hypernasality ( P = 0.015). Hyponasality did not change significantly after surgery ( P = 0.964). No patient developed sleep-disordered breathing. CONCLUSION: BBFRP resulted in a measurable improvement in hypernasal speech, audible nasal emission, and speech acceptability without significant changes in hyponasality or risk of obstructive sleep apnea. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Pharyngeal Airway Changes Following Mandibular Distraction Osteogenesis as Evaluated with Laryngoscopy.

PURPOSE: Mandibular distraction osteogenesis (MDO) may improve airway grade in patients with Robin Sequence (RS), but little is known about the response of the oropharyngeal airway to the distraction process in cases of tongue base obstruction (TBAO). This study used drug-induced sleep endoscopy (DISE) to evaluate the impact of MDO on the oropharynx. METHODS: RS patients with severe obstructive sleep apnea (OSA) were prospectively enrolled, and underwent DISE prior to MDO, and at the time of distractor removal. Laryngoscopy views, glossoptosis degree, polysomnography (PSG) results, oxygen saturations and airway measurements were compared pre- and post-MDO. RESULTS: Twenty patients met inclusion criteria. At the time of distractor placement, a grade II laryngoscopic view was most frequently observed (63%), and one patient (5%) had a grade I view. Median obstructive apnea hypopnea index (OAHI) improved after MDO (49.1 [30.2-74.0] to 9.1, [3.9-18.0], p ≤ .001). Median oxygen saturation nadir also improved (preoperative 69% [60-76] to 85% [82-91], p ≤ .001). At distractor removal, mean laryngoscopic view improved (p ≤ .002) with no views that were grade 3 or higher. Median intraoperative oropharyngeal width improved, (3.1 mm [2.8-4.4] to 6.0 mm [4.4-6.8], p ≤ .021), as did median cephalometric anteroposterior oropharyngeal width (3.5 mm [2.7-4.1] to 6.3 mm [5.6-8.2], p ≤ .002). CONCLUSION: Following MDO, RS patients with TBAO have an approximate doubling of oropharyngeal width and an improvement in laryngoscopic grade. These findings likely contribute to improved oxygenation, OAHI and ease of intubation.

Trigeminal Schwannoma: A Retrospective Analysis of Endoscopic Endonasal Management, Treatment Outcomes, and Neuropathic Sequelae.

Introduction Trigeminal schwannomas (TS) are rare skull base tumors that have been associated with significant neuropathic sequalae for patients. The authors aim to evaluate the clinical features, treatment outcomes, and neuropathic sequelae following endoscopic endonasal approach (EEA) for TS. Methods The study involves a retrospective review of patients who underwent EEA for resection of TS at a single academic institution between 2004 and 2020. Radiographic and clinical data were recorded and analyzed. Results A total of 16 patients were abstracted, with a mean age at the time of surgery of 44 years with a slight female (1.83:1) predominance. Primary preoperative symptomatology included facial pain/neuralgia ( n = 5, 31.3%), facial hypoesthesia ( n = 4, 25.0%), and headache ( n = 4, 25.0%). Following TS resection, patients were found to have facial hypoesthesia ( n = 11, 68.8%), neuropathic keratopathy ( n = 4, 25.0%), and mastication musculature atrophy ( n = 3, 18.8%). Patients with preoperative facial pain/neuralgia ( n = 5, 31.3%) were significantly more likely to try adjunctive pain therapies ( p = 0.018) as well as seek pain consultation ( p = 0.018). Patients with preoperative migraines ( n = 2, 12.5%) were significantly more likely to trial adjunctive pain therapies ( p = 0.025) and undergo evaluation with pain specialists ( p = 0.025). Finally, patients with preoperative pharmacologic agent utilization were significantly more likely to trial adjunctive pain therapies ( p = 0.036) and pursue pain consultation ( p = 0.036). Conclusion Some degree of trigeminal dysfunction may be more common than previously reported following EEA for TS resection. Factors that appear to play a role in the development of trigeminal dysfunction include pre-existing pain syndromes such as facial pain/neuralgia or headache and preoperative medication utilization.

Intracranial Pressure Patterns in Children with Sagittal Craniosynostosis.

BACKGROUND: Elevated intracranial pressure (ICP) in sagittal craniosynostosis has a wide spectrum of reported incidence, and patterns are not well understood across infancy and childhood. Characterizing the natural history of ICP in this population may clarify risks for neurocognitive delay and inform treatment decisions. METHODS: Infants and children with sagittal craniosynostosis and unaffected control subjects were prospectively evaluated with spectral-domain optical coherence tomography (OCT) from 2014-2021. Elevated ICP was determined based on previously validated algorithms utilizing retinal OCT parameters. RESULTS: Seventy-two patients with isolated sagittal craniosynostosis, and 25 control subjects were evaluated. Overall, 31.9% (n=23) of patients with sagittal craniosynostosis had evidence of ICP ≥15 mmHg, and 27.8% (n=20) of patients had ICP ≥20 mmHg.Children with sagittal craniosynostosis younger than 6 months of age were more likely to have normal intracranial pressure (88.6% <15 mmHg, 91.4% <20 mmHg) than those between 6-12 months of age (54.5%, p=.013; 54.5%, p=.005) and than those older than 12 months of age (46.2%, p<.001; 53.8%, p=.001). Intracranial pressure was directly correlated with severity of scaphocephaly (p=.009). No unaffected control subjects at any age exhibited retinal thickening suggestive of elevated ICP. CONCLUSIONS: Elevated ICP is rare in isolated sagittal craniosynostosis below 6 months of age, but becomes significantly more common after 6 months of age, and may correlate with severity of scaphocephaly.

Implantable, Bioresorbable Radio Frequency Resonant Circuits for Magnetic Resonance Imaging.

Magnetic resonance imaging (MRI) is widely used in clinical care and medical research. The signal-to-noise ratio (SNR) in the measurement affects parameters that determine the diagnostic value of the image, such as the spatial resolution, contrast, and scan time. Surgically implanted radiofrequency coils can increase SNR of subsequent MRI studies of adjacent tissues. The resulting benefits in SNR are, however, balanced by significant risks associated with surgically removing these coils or with leaving them in place permanently. As an alternative, here the authors report classes of implantable inductor-capacitor circuits made entirely of bioresorbable organic and inorganic materials. Engineering choices for the designs of an inductor and a capacitor provide the ability to select the resonant frequency of the devices to meet MRI specifications (e.g., 200 MHz at 4.7 T MRI). Such devices enhance the SNR and improve the associated imaging capabilities. These simple, small bioelectronic systems function over clinically relevant time frames (up to 1 month) at physiological conditions and then disappear completely by natural mechanisms of bioresorption, thereby eliminating the need for surgical extraction. Imaging demonstrations in a nerve phantom and a human cadaver suggest that this technology has broad potential for post-surgical monitoring/evaluation of recovery processes.

Frontal sinus hypoplasia in unoperated older patients with craniosynostosis: a pilot study.

PURPOSE: The purpose of this study is to determine whether patients with unoperated craniosynostosis have different frontal sinus pneumatization than unaffected controls. METHODS: Retrospective review was performed between 2009 and 2020 of previously unoperated patients with craniosynostosis older than 5 years old at first presentation to our institution. Total frontal sinus volume (FSV) was calculated using 3D volume rendering tool in Sectra IDS7 PACS system. Age-matched normative FSV data was collected from 100 normal CT scans for the control group. The two groups were statistically compared using Fisher's exact test and T-test. RESULTS: Study group included nine patients, 5-39 years old, median age 7 years. Frontal sinus pneumatization was absent in 12% of the normal 7-year-old controls, while frontal sinus pneumatization was absent in 89% of the studied craniosynostosis patients (p < .001). Mean FSV of the study group (113 ± 340 mm3) was significantly different from that of age matched control mean FSV (2016 ± 2529 mm3) (p = .027). CONCLUSIONS: Frontal sinus pneumatization is suppressed in unreleased craniosynostosis and may be an intracranial space conservation phenomenon. This absent frontal sinus can have implications in future frontal region trauma and frontal osteotomies.

Double-Reversed Costal Cartilage Graft for Nasal Reconstruction.

SUMMARY: Costal cartilage provides the ideal graft for reconstruction of the nasal dorsum and tip given its abundant supply and flexural strength. Nevertheless, autologous costal cartilage grafts can be plagued by warping. Several techniques have been devised to offset the intrinsic warping effects of cartilage, but current techniques have several disadvantages. Herein, we present a multimedia demonstration of the double-reversed technique for costal cartilage reconstruction. This strategy is unique in its dual axis of rotation to offset warp in all dimensions. This technique can be performed with conventional instruments, does not introduce foreign material, and provides robust support to counteract the often scarred and contracted soft tissue envelope.

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

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.

Examination of Outcome Disparities in Reports of Prepectoral and Subpectoral Direct-to-Implant Reconstruction: A Systematic Review and Meta-analysis.

BACKGROUND: There are mixed results in surgical complications regarding the usage of prepectoral versus subpectoral implant placement in direct-to-implant breast reconstruction. This study aimed to provide a comprehensive synthesis of surgical complications between the subpectoral and prepectoral reconstructive method. METHODS: PubMed, Embase, and Cochrane were searched for literature published up until December 2022. Studies that compared subpectoral and prepectoral breast reconstruction and reported at least one postoperative complication were included. The following 8 major outcomes were included: revision and reoperation, capsular contracture, explantation, seroma, hematoma, infection, skin necrosis, and animation deformity. Systematic review and meta-analysis were performed to compare outcomes of the 2 techniques. Subgroup analysis was performed to compare whether practice differences in different countries may have an impact on outcomes. RESULTS: A total of 18 studies were identified in our literature search. Two thousand three hundred sixty patients were included, representing a total of 3135 breasts. Our analysis demonstrated that prepectoral reconstruction had significantly lower odds of developing postoperative hematoma [odds ratio (OR), 0.62; P = 0.05], seroma (OR, 0.67; P = 0.01), infection (OR, 0.64; P = 0.03), revision and reoperation (OR, 0.44; P < 0.00001), and animation deformity (OR, 0.01; P < 0.00001), compared with the subpectoral method. Subgroup analysis showed that differences between 3 countries (United States, Korea, Italy) are low (all subgroup heterogeneity test P > 0.1). CONCLUSIONS: While both subpectoral and prepectoral are safe methods for breast reconstruction, the prepectoral technique may lead to lower odds of developing multiple major postoperative complications.

National Trends in Orthognathic Surgery: A Multi-Institutional Analysis of 6640 Patients.

BACKGROUND: LeFort I osteotomy (LF1) and bilateral sagittal split osteotomy (BSSO) have unique operative challenges and inherent anatomic considerations that predispose to certain adverse outcomes, yet their respective complication profiles continue to be debated given conflicting results from single-center investigations. The purpose of this study is to perform a multi-institutional analysis of complications, socioeconomic trends, and financial charges associated with orthognathic surgery. METHODS: A retrospective cohort study was conducted of orthognathic procedures performed in the United States from 2010 through 2020 using the Pediatric Health Information System. Patients younger than 12 years of age were excluded. Medical complications, surgical complications, and admission costs were compared across procedures. Socioeconomic determinants and trends across regions of the country were also analyzed. RESULTS: During the study interval, 6640 patients underwent orthognathic surgery, including LF1 (59.2%, n=3928), BSSO (14.4%, n=959), and double-jaw surgery (26.4%, n = 1753). Patients undergoing LF1 were more likely to experience overall complications ( P <0.001), infections ( P <0.001), and blood transfusions ( P <0.001) than those undergoing BSSO. High-volume hospitals were more likely to perform double-jaw procedures than other hospitals ( P <0.001), yet high-volume hospitals were less likely to have surgical complications ( P =0.014). Patient admission charges related to orthognathic operations at high-volume hospitals were less than other hospitals ( P <0.001). Household income was higher for orthognathic procedures performed at high-volume hospitals ( P <0.001). White patients were 1.5 times more likely to choose a farther, higher volume hospital for orthognathic surgery than the one locally available ( P =0.041). CONCLUSIONS: LeFort I osteotomy procedures had higher infection and transfusion rates than BSSO procedures. High-volume hospitals were more likely to perform double-jaw procedures, yet high-volume hospitals had fewer complications and decreased admission charges. Future study will be needed to further elucidate case-mix index details and socioeconomic determinants of health contributing to these disparities.

A Longitudinal Study of Improvement in Nasal Airway Obstruction after Secondary Cleft Rhinoplasty.

BACKGROUND: Nasal airway obstruction is an increasingly recognized phenomenon in patients with cleft lip and/or palate and has the potential to significantly affect quality of life in this patient population. To date, the effect of secondary cleft rhinoplasty on cleft-related nasal airway obstruction has not been studied. METHODS: Patients undergoing secondary cleft rhinoplasty at the Children's Hospital of Philadelphia from 2015 to 2021 were identified. Preoperative and postoperative Nasal Obstruction Symptom Evaluation scores were recorded. Alterations in scores were evaluated for variation depending on patient characteristics, operative maneuvers, and postoperative nasal stenting. RESULTS: Nasal airway obstruction was present in mild to moderate severity in patients before secondary cleft rhinoplasty. Postoperatively, obstruction improved or resolved in the domains of nasal blockage/obstruction, trouble breathing through the nose, and ability to get enough air through the nose during exertion (P < 0.05). Overall composite Nasal Obstruction Symptom Evaluation scores improved (P < 0.05). Lateral crural strut grafting was associated with improvement in nasal blockage, whereas alar revision and tip sutures were associated with worsening in specific nasal symptoms. Patients who underwent nasal stenting were found to report less trouble breathing after surgery than patients who did not (P < 0.05). CONCLUSIONS: Nasal airway obstruction is present in mild to moderate severity in patients with cleft lip and/or palate, and the subjective severity of obstruction is decreased by secondary cleft rhinoplasty. Specific operative maneuvers are associated with alterations in nasal airway obstructive symptoms, and nasal stenting is associated with an improvement in trouble breathing after secondary cleft rhinoplasty. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Speech Outcomes following Mandibular Distraction Osteogenesis for Robin Sequence: Midchildhood Results.

BACKGROUND: The aim of this study was to compare midchildhood speech outcomes in patients with nonsyndromic Robin sequence with cleft palate (RSCP) treated with mandibular distraction osteogenesis (MDO) to patients with nonsyndromic Veau class I and Veau class II cleft palate (CP). METHODS: The authors performed a retrospective review of patients with nonsyndromic Robin sequence from 2000 to 2017, comparing those who underwent MDO to patients with nonsyndromic CP. Demographics, operative details, length of hospital stay, complications, and Pittsburgh Weighted Speech Scale scores were collected. RESULTS: Thirty-three patients met inclusion criteria in the MDO group with 127 patients as controls. Despite similar median age (RSCP, 4.5 years; CP only, 4.6 years) and Veau cleft type at early evaluation, there was a significant increase in composite Pittsburgh Weighted Speech Scale score within the MDO cohort ( P ≤ 0.002); specifically, with worse visible nasal emission ( P ≤ 0.007), hypernasality ( P ≤ 0.001), and compensatory articulation ( P ≤ 0.015). However, these differences were not present at age-matched midchildhood evaluation (median, RSCP, 6.5; CP only, 7.1; P ≥ 0.092). Median age-matched follow-up was 6.4 years in the MDO group and 7.1 years in the control group ( P ≥ 0.136). There was also no difference in the rate of secondary speech surgery at midchildhood evaluation ( P ≥ 0.688). CONCLUSIONS: The authors' retrospective comparison of speech outcomes in RSCP versus CP only demonstrates no difference in midchildhood speech, conflicting with recent reports. Although patients with Robin sequence treated with MDO had worse visible nasal emission, hypernasality, and compensatory articulation in early childhood, this appears to have resolved in the interim without additional intervention. Longitudinal follow-up is needed to fully understand the speech ramifications of RSCP. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, II.

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

OBJECTIVE: 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. DESIGN: Retrospective cohort study. SETTING: Tertiary Pediatric Hospital during 2004-2020. PATIENTS: 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. MAIN OUTCOME MEASURES: Patient characteristics, hospital/operative details, postoperative complications, and polysomnographic (PSG) data were compared. RESULTS: 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. CONCLUSIONS: 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.

Socioeconomic Disparities in Cleft Lip Care.

OBJECTIVE: The purpose of this study was to utilize a multicenter dataset to elucidate whether socioeconomic factors were associated with access to cleft lip surgery, treatment by higher-volume providers, and family choice for higher-volume centers. DESIGN: Retrospective cohort study. SETTING: Hospitals participating in the Pediatric Health Information System. PATIENTS: Primary cleft lip repair performed in the United States between 2010 and 2020. OUTCOMES: Travel distance, hospital volume, hospital choice. RESULTS: During the study interval, 8954 patients underwent unilateral (78.4%, n = 7021) or bilateral (21.6%, n = 1933) primary cleft lip repair. Patients with unilateral cleft lip were repaired significantly earlier if they were White (P < .001) and significantly later if they lived in an urban community (P = .043). Similarly, patients with bilateral cleft lip were repaired significantly earlier if they were White (P < .001). Patients from above-median income households (P = .011) and living in urban communities (P < .001) were significantly more likely to be treated at high-volume hospitals, whereas those living in underserved communities (P < .001) were significantly less likely to be treated at high-volume hospitals. White patients were significantly more likely to be treated by high-volume surgeons (P < .001). Patients with White race were significantly more likely to choose a higher-volume hospital than the one most locally available (P < .001). CONCLUSIONS: Patients with White race are more likely to travel farther and be treated by high-volume surgeons although at smaller hospitals. Patients from underserved areas travel significantly farther for cleft care and are treated at lower-volume hospitals. Patients in urban communities have shorter travel distances and are treated at higher-volume hospitals.
