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.

Narcotic Utilization After Cleft Lip Repair: Does Local Anesthetic Choice Matter?

To analyze whether the choice of intraoperative local anesthetic for cleft lip repair is associated with the amount of perioperative narcotic utilization.Retrospective cohort study.Hospitals participating in the Pediatric Health Information System.Primary cleft lip repairs performed in the United States from 2010 to 2020.Local anesthesia injected-treatment with lidocaine alone, bupivacaine alone, or treatment with both agents.Perioperative narcotic administration.During the study interval, 8954 patients underwent primary cleft lip repair. Narcotic utilization for unilateral (P < .001) and bilateral (P = .004) cleft lip repair has decreased over the last 5 years. Overall, 21.8% (n = 1950) of infants were administered perioperative narcotics for cleft lip repair, such that 14.3% (n = 1282) required narcotics on POD 0, and 7.2% (n = 647) required narcotics on POD 1.In this study, 36.5% (n = 3269) patients received lidocaine, 22.0% (n = 1966) patients received bupivacaine, and 19.7% (n = 1762) patients received both local anesthetics. Administration of any perioperative narcotic was significantly lower in patients receiving both lidocaine and bupivacaine than those receiving only lidocaine (P = .001, 17.5% vs 21.7%) or only bupivacaine (P < .001, 17.5% vs 22.9%). Narcotic utilization on the day of surgery was significantly lower in patients receiving both lidocaine and bupivacaine than those receiving only lidocaine (P < .001, 11.5% vs 15.1%) or only bupivacaine (P = .004, 11.5% vs 14.6%). Narcotic utilization on the first postoperative day was significantly lower in patients receiving both lidocaine and bupivacaine than those receiving only bupivacaine (P = .009, 5.9% vs 8.1%). CONCLUSIONS: In children undergoing cleft lip repair, local anesthetic combination of lidocaine and bupivacaine is associated with decreased perioperative narcotic use compared to lidocaine or bupivacaine alone.

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.

Multimodal Treatment of Robin Sequence Utilizing Mandibular Distraction Osteogenesis and Continuous Positive Airway Pressure.

Mandibular distraction osteogenesis (MDO) and continuous positive airway pressure (CPAP) may each have a role in effectively treating tongue-based airway obstruction (TBAO) in Robin sequence (RS). This study describes longitudinal outcomes after treatment of TBAO with CPAP and/or MDO.Retrospective cohort study.Tertiary Pediatric Hospital.A total of 129 patients with RS treated with CPAP and/or MDO from 2009 to 2019 were reviewed. Subjects receiving baseline and at least one follow-up polysomnogram were included. 55 who underwent MDO ± CPAP and 9 who received CPAP-only treatment were included.Patient characteristics, feeding, and polysomnographic data were compared and generalized linear mixed modeling performed.Baseline obstructive apnea-hypopnea index (OAHI) was greater in the MDO-treated group (median x˜ = 33.7 [interquartile range: 26.5-54.5] than the CPAP-treated group (x˜ = 20.3[13.3-36.7], P ≤ .033). There was significant reduction in OAHI following treatment with CPAP and MDO modalities, P ≤ .001. SpO2 nadir after MDO was lower in syndromic (x˜ = 85.0[81.0-87.9] compared to nonsyndromic patients (x˜ = 88.4[86.8-90.5], P ≤ .005.) CPAP was utilized following MDO in 2/24 (8.3%) of nonsyndromic and 16/31 (51.6%) of syndromic subjects (P ≤ .001,) for a median duration of 414 days. Three patients (5%) underwent tracheostomy, all had MDO. Nasogastric tube feeding at hospital discharge was more common following MDO (44, 80%) than CPAP-only (4, 44.4%, P ≤ .036), but did not differ at 6-month follow-up (P ≥ .376).CPAP appears to effectively reduce obstructive apnea in patients with RS and moderate TBAO and be a useful adjunct in syndromic patients following MDO with improved but persistent obstruction.

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.

Comprehensive Long-Term Outcomes Following Mandibular Distraction Osteogenesis.

OBJECTIVE: To describe long-term outcomes and complications following mandibular distraction osteogenesis (MDO) in a diverse patient cohort. DESIGN: Cross-sectional study. SETTING: Single tertiary-care pediatric center. PATIENTS: Forty-eight patients previously undergoing MDO with minimum 4-year follow-up. MAIN OUTCOME MEASURES: Respiratory outcomes, feeding patterns, dental development, motor/sensory nerve function, temporo-mandibular joint function, and postsurgical scarring. RESULTS: Forty-six patients with a median age of 7 years were evaluated. Of 20 nonsyndromic patients, none required additional airway procedures, none required continuous positive airway pressure (CPAP) during sleep, and 19 (95%) fed exclusively by mouth. Among 26 syndromic patients, 7 (27%) required CPAP and 8 (31%) were tube fed. Permanent first molar differences were seen in the majority of subjects; patterns of damage interfering with function were more common in syndromic (13/28, 46%) compared to nonsyndromic (5/24, 21%; P = .014) subjects. MDO prior to age two was associated with more frequent and worse dental damage (P = .001). Inferior alveolar nerve and marginal mandibular nerve function were fully intact in 37 (80%) and 39 (85%) of patients, respectively. Three patients (6%), all with associated genetic syndromes, demonstrated severe nerve impairment. By the Vancouver scar scale, ≥ 80% of surgical scars were rated in the most favorable category for each quality assessed. Temporomandibular joint dysfunction was rare. CONCLUSIONS: MDO shows highly favorable long-term respiratory, feeding, nerve, and scar outcomes in nonsyndromic patients, although permanent molar changes not precluding tooth viability are commonly seen. Patients with associated syndromes demonstrate respiratory and feeding benefits, but higher rates of dental and nerve abnormalities.

Mandibular Distraction Osteogenesis for Tongue-Based Airway Obstruction Without Micrognathia.

PURPOSE: Mandibular distraction osteogenesis (MDO) effectively treats tongue-based airway obstruction (TBAO) in micrognathic patients with Robin Sequence. Mandibular distraction osteogenesis may also address TBAO in certain nonmicrognathic patients who have severe obstructive apnea, although there is no current literature to guide MDO use in these atypical patients. This study describes outcomes of MDO in a series of patients with TBAO without micrognathia. METHODS: Patients who underwent MDO for TBAO from 2013-20 were reviewed, and patients with micrognathia were excluded. Study subjects received baseline/follow up polysomnography. Polysomnography variables, including Obstructive Apnea Hypopnea Index, oxyhemoglobin saturation nadir (SpO2 nadir), percent sleep time end tidal CO2 greater than 50 mm Hg (%ETCO2 > 50), and respiratory-related arousals were compared before and after MDO. Demographics, syndromic/cleft palate status, airway anomalies, respiratory support, and feeding outcomes were collected. RESULTS: One hundred and twenty-four patients underwent MDO during this study period; 5 were nonmicrognathic and included in analysis. Sixty percent (n = 3) of the cohort was syndromic: 1 patient each had Trisomy 9, Beckwith Wiedemann syndrome, and duplicated pituitary gland plus syndrome. Forty percent (n = 2) of patients had a cleft palate, 60% (n = 3) had laryngomalacia, and 40% had tracheomalacia. Median (range) age at MDO was 53 days (47-167 days), and median length of distraction was 16 mm (14-20 mm). After MDO, median Obstructive Apnea Hypopnea Index decreased from x̃ = 60.7/h (11.6-109.4) to x̃ = 5.3/h (3.5-19.3) (P = 0.034). SpO2 nadir increased (69% [58-74] to 85% [80-88], P = 0.011), and median %ETCO2 > 50 mm Hg decreased (5.8% [5.2-30.1] to 0.0% [0.0-1.3], P ≤ 0.043). Continuous positive airway pressure was used by all patients immediately after MDO, and at 6 months postoperatively, 1 patient remained on continuous positive airway pressure and 1 patient required supplemental oxygen. At last follow up, no patients had significant residual airway obstruction or required a tracheostomy. CONCLUSIONS: Mandibular distraction osteogenesis can effectively treat severe TBAO in some patients without micrognathia that would otherwise be candidates for tracheostomy. When used in select patients, MDO significantly improves obstructive sleep apnea and reduces need for ventilatory support, although feeding support is still needed in most patients at 6 months. Further study in a larger cohort will help identify appropriate candidates for MDO and characterize outcomes of unique patient populations.

Geographic Financial Analysis of Craniosynostosis Surgery in the United States.

BACKGROUND: The purpose of this study was to investigate the financial implications of demographic and socioeconomic factors upon the cost of surgical procedures for craniosynostosis. METHODS: A retrospective cohort study was conducted of admissions for craniosynostosis surgery in the United States from 2015 through 2020 using the Pediatric Health Information System. Patient demographics, case volume, and surgical approach were analyzed in context of hospital charges. RESULTS: During the study interval, 3869 patients were admitted for surgery for craniosynostosis. In multivariate regression accounting for demographic and socioeconomic factors, hospital admission charges were significantly higher in patients with longer hospital length of stay ( P < 0.001), longer ICU length of stay ( P < 0.001), living in an underserved area ( P = 0.046), preoperative risk factors ( P = 0.016), and those undergoing open procedures ( P < 0.001); hospital admission charges were significantly lower in patients with White race ( P = 0.020) and those treated at high-volume centers ( P < 0.001). In multivariate regression, ICU length of stay was significantly higher in patients with preoperative risk factors ( P < 0.001), undergoing open procedures ( P < 0.001), government insurance ( P = 0.018), and not treated at high-volume centers ( P = 0.005). There were significant differences in admission charges ( P < 0.001), charge-to-cost ratios ( P < 0.001), and likelihood of being treated at high-volume craniofacial centers ( P < 0.001) across geographic regions of the country. CONCLUSIONS: In the United States, there is significant sociodemographic variability in charges for craniosynostosis care, with increased hospital charges independently associated with non-White race, preoperative risk factors, and living in an underserved area.

What is the Role of Midfacial Sutures in the Development of Maxillary Hypoplasia in Children With Cleft Palate?

ABSTRACT: Maxillary hypoplasia is common in patients with cleft lip and palate (CL/P), and its etiology is incompletely understood. The purpose of this study is to evaluate facial suture patency in patients with CL/P and maxillary hypoplasia. The authors hypothesize that patients with CL/P will demonstrate higher rates of premature midfacial suture fusion in comparison to unaffected controls. Skeletally mature patients with CL/P and midface hypoplasia were identified, along with a cohort of unaffected age- and sex-matched controls. High-resolution facial computed tomography scans were evaluated for the presence of facial suture fusion. Utilizing a previously published suture fusion grading scale, the facial sutures were classified as open, partially open, closed, or pathologically absent. Thirty-one CL/P patients with midface hypoplasia were identified, with age and sex-matched controls. The frequency of intermaxillary suture fusion did not differ between patients with CL/P and unaffected controls (P  > 0.05.) Pathologic absence of the midpalatal suture was more commonly present in patients with CL/ P and midface hypoplasia in comparison to unaffected controls (P < 0.05.) The role of midfacial sutures in the development of midfacial hypoplasia seen in CLP has not previously been studied or described. Our data show that the midpalatal suture is frequently pathologically absent in patients with CL/P and maxillary hypoplasia. The authors did not identify statistically significant differences in other midfacial sutures between patients with CL/P and controls, leading us to conclude that midfacial sutures may not play a key role in the development of midfacial hypoplasia.

Nasal Obstruction Evaluation After LeFort I Osteotomy: A Pilot Study.

ABSTRACT: Previous literature has documented changes in nasal obstruction after acute LeFort I osteotomy. However, there is a paucity of studies that evaluate distraction-mediated LeFort I (DO-LFI) without concomitant intranasal interventions using the nasal obstruction symptom evaluation (NOSE) scale in Class III patients. The purpose of this study is to objectively evaluate nasal obstruction quality of life through the NOSE scale in patients undergoing DO-LFI. Inclusion into the study required both a preoperative (1 year ≤ date of service) and postoperative (≥6 months and ≤2 years) NOSE scale administration. Nasal obstruction symptom evaluation scales were compared using Wilcoxon signed rank test. There was a significant difference in composite NOSE scales, x̃ = 8.0 (interquartile range: 4.0-11.0), x̃ = 1.0 (interquartile range: 1.0-3.0), P < 0.017, preoperatively and postoperatively respectfully. Additionally, when looking at individual components of the NOSE scale, nasal congestion or stuffiness, and trouble breathing through nose were significantly improved after DO-LFI (P < 0.017). Nasal blockage or obstruction (P > 0.084) and trouble breathing when exercising (P > 0.076) trended towards significant improvement, as well. Trouble sleeping did not differ, P > 0.611. We elucidate, in this pilot study, that there is an association between DO-LFI and patient reported nasal obstructive symptoms. Future prospective studies utilizing the NOSE scale are needed to determine causality.

Endoscopic-Assisted Fronto-Orbital Distraction Osteogenesis: Initial Patient Report.

BACKGROUND: The purpose of this manuscript is to introduce a novel endoscopic-assisted approach for creation of osteotomies and distractor hardware placement for unicoronal craniosynostosis. METHODS: Only three small incisions are performed, one at the anterior fontanelle, pterional region, and upper lateral blepharoplasty location. Unicoronal strip craniectomy and osteotomies in temporal bone, nasofrontal junction, lateral orbital rim, sphenoid wing, orbital roof, and contralateral frontal bone are performed through these incisions with the assistance of a 30° 5-mm endoscope. One linear cranial distractor is inserted through the pterional incision and fixated across the unicoronal suturectomy. RESULTS: Endoscopic-assisted fronto-orbital distraction osteogenesis has been performed on 3 patients with unicoronal craniosynostosis. Median age at surgery was 5.4 months (95%CI 5.0-6.1). Median operative duration was 98 minutes (95%CI 91-112), and estimated blood loss was 25 mL (95%CI 15-150). Median length of distraction achieved was 25.7 mm (95%CI 21.9-28.0), based on lateral skull x-rays obtained on the last day of activation. Distractors were removed 2.3 months postoperatively (95%CI 2.1-3.1), and operative duration of distractor removal was 20 minutes (95%CI 19-29). There was 1 complication, a transient cerebrospinal fluid leak thought to have been caused by a pinpoint injury to the dura at the nasofrontal junction, which was managed expectantly and resolved spontaneously by the fourth postoperative day. CONCLUSIONS: Endoscopic-assisted fronto-orbital distraction osteogenesis is a promising treatment modality for children with unicoronal craniosynostosis combining the benefits of distraction osteogenesis with a minimally invasive approach. Additional experience and follow-up are needed to determine its utility, safety, and longevity.

Utility of Preoperative Helmet Molding Therapy in Patients With Isolated Sagittal Craniosynostosis.

ABSTRACT: The purpose of this study was to review our institution's experience using helmet molding therapy in children with isolated non-syndromic sagittal craniosynostosis before placement of cranial springs and provide objective measurements of craniometric changes to help determine its role in treatment.Patients who underwent preoperative helmet molding therapy for sagittal craniosynostosis were retrospectively reviewed. Three-dimensional surface tomography scans were used to measure head circumference, cranial width, cranial length, cranial index (CI), and cranial vault asymmetry.Seventeen patients underwent orthotic helmeting therapy before spring mediated cranial vault expansion. Patients spent a median of 48 days (interquartile range [IQR] 32, 57) in preoperative orthotic helmeting therapy. There were increases in both cranial width and length post-helmeting (median: 107.5 mm [IQR 104.8, 110.4] versus 115.6 mm [IQR 114.5, 119.3]; P < 0.001) (median: 152.8 mm [IQR 149.2, 154.9] versus 156.8 mm [IQR 155.0, 161.5]; P < 0.001), respectively. There was a greater increase in cranial width (P = 0.015). Consequently, patients' CI improved after preoperative helmeting (median: 0.702 [IQR 0.693, 0.717] versus 0.739 [0.711, 0.752]; P < 0.001). There was no evidence of growth restriction from helmeting (pre-helmeting Head circumference [HC]: median 96.8 percentile [IQR 90.6, 99.9] versus post-helmeting HC: 98.7 percentile [IQR 94.7, 99.8]; P = 0.109).Preoperative helmeting in patients with non-syndromic isolated sagittal craniosynostosis can be used to improve CI before surgical correction. Significant benefits can be achieved in shorter preoperative helmeting durations than previously reported with no evidence of cranial growth restriction, which supports its feasibility and utility in children undergoing spring mediated cranial vault expansion.

Does the Geographical Distribution of Facial Trauma Surgeons Correspond to Facial Trauma Burden? A Nationwide Population-Level Analysis.

ABSTRACT: It is unknown if craniofacial trauma services are inequitably distributed throughout the US. The authors aimed to describe the geographical distribution of craniofacial trauma, surgeons, and training positions nationwide. State-level data were obtained on craniofacial trauma admissions, surgeons, training positions, population, and income for 2016 to 2017. Normalized densities (per million population [PMP]) were ascertained. State/ regional-level densities were compared between highest/lowest. Risk-adjusted generalized linear models were used to determine independent associations. There were 790,415 craniofacial trauma admissions (x? = 2330.6 PMP), 28,004 surgeons (x? = 83.5 PMP), and 746 training positions (x? = 1.9 PMP) nationwide. There was significant state-level variation in the density PMP of trauma (median 1999.5 versus 2983.5, P   <  0.01), surgeon (70.8 versus 98.8, P  < 0.01), training positions (0 versus 3.4, P  < 0.01) between lowest/highest quartiles. Surgeon distribution was positively associated with income and training positions density ( P  < 0.01). Subanalysis revealed that there was an increase of 6.7 plastic and reconstructive surgeons/PMP for every increase of 1000 trauma admissions/PMP ( P  < 0.01). There is an uneven state-level distribution of facial trauma surgeons across the US associated with income. Plastic surgeon distribution corresponded closer to craniofacial trauma care need than that of ENT and OMF surgeons. Further work to close the gap between workforce availability and clinical need is necessary.

Risk Factors for Occipital Step-Off Deformities in Posterior Vault Distraction Osteogenesis.

PURPOSE: The goal of this study was to investigate patient specific factors and surgical techniques that affect occipital step-off deformity in children undergoing posterior vault distraction osteogenesis (PVDO). METHODS: Patients who underwent PVDO were retrospectively reviewed and included if a high resolution three-dimensional computed tomography scan was available 1-year post-distractor removal. Two craniofacial surgeons were blinded to individual subjects and presented with 3 still images of three-dimensional bone reconstructions and asked to rate the degree of step off: none, mild, moderate, or severe. The data were analyzed with multinomial logistic regressions and other appropriate statistics. RESULTS: Forty-one patients met inclusion criteria. All patients had multisuture or bicoronal craniosynostosis. Multinomial logistic regression identified age at PVDO (Cox and Snell = 0.487, P < 0.001) as a predisposing factor and one potentially protective factor, height of osteotomy (Cox and Snell = 0.394, P = 0.004) in univariate models. Post-hoc pairwise Mann-Whitney U test revealed there was decreased step-off rating when comparing osteotomy below torcula (median 0, [IQR 0, 3]) and above torcula (median 3 [IQR 1, 4]; P = 0.036) as well as a decreased step-off when below inion (median 0 [IQR 0, 1]; P = 0.001) was compared to above the torcula. CONCLUSIONS: Older age at PVDO predict increased risk of developing an occipital step-off deformity after PVDO, while design of the occipital osteotomy below the inion is protective. Barrel staves with greenstick outfracture did not lower the risk of occipital step-off in this sample, the reasons for which are unclear.

Cleft Rhinoplasty: Does Timing and Utilization of Cartilage Grafts Affect Perioperative Outcomes?

BACKGROUND: The purpose of this study was to evaluate the epidemiology and perioperative complications of different reconstructive strategies to correct cleft nasal deformity, with particular attention paid to type and timing of cartilage grafting. METHODS: Retrospective cohort study was conducted of cleft rhinoplasty performed between 2012 and 2017 in North America utilizing the American College of Surgeons National Surgical Quality Improvement Program- Pediatric hospital network. Medical/surgical complications, reoperations, and readmissions within 30 days postoperatively were analyzed with appropriate statistics. RESULTS: During the study interval, 3317 pediatric patients underwent cleft rhinoplasty, with 8.0% involving the use of cartilage grafts. Ear cartilage was significantly more commonly used for intermediate repair, whereas rib cartilage was more commonly used for late repair (P=0.006). Overall, rhinoplasties with ear cartilage grafts had shorter procedure durations than those without cartilage grafts (P=0.005), whereas those with rib cartilage grafts had increased procedure duration (P<0.001). The use of cartilage grafts was not associated with increased complications in either intermediate or late cleft rhinoplasty. Patients with bilateral clefts were more likely to undergo rhinoplasty with cartilage grafts overall (P=0.047) and with cartilage grafts for late reconstruction (P=0.039). CONCLUSIONS: Ear cartilage is most frequently utilized for intermediate repair, whereas rib cartilage is most frequently utilized for late repair during cleft rhinoplasty. Ear cartilage grafts are associated with significantly decreased procedure duration, whereas rib cartilage grafts are associated with significantly increased procedure duration. Not surprisingly, cleft rhinoplasty is relatively safe, with a 2% overall short-term complication rate.

Surgical reconstruction of pilonidal sinus disease with concomitant extracellular matrix graft placement: a case series.

BACKGROUND: Pilonidal sinus disease (PSD) is a chronic inflammatory disease affecting the soft tissue of the sacrococcygeal region and remains a challenging disease for clinicians to treat. The optimal treatment for PSD remains controversial and recent reports describe several different surgical approaches offering different benefits. Approximately 40% of initial incision and drainage cases require subsequent surgery. Due to high recurrence rates and postoperative complications, a more complex revision surgery involving a flap reconstruction may be required. We hypothesised that the combination of an extracellular matrix (ECM) graft with tissue flap reconstruction may decrease the postoperative complications and recurrence rates for PSD. METHOD: We report a retrospective case series using a surgical flap reconstruction with concomitant implantation of an ovine forestomach ECM graft under a fasciocutaneous flap with an off-midline closure for recurrent PSD, where previously surgical intervention had failed due to wound dehiscence and/or recurrent disease. RESULTS: The case series included six patients. After three weeks, all patients except one were fully healed, and the sixth was fully healed by week 4; all wounds remained fully healed at 12 weeks. All patients achieved good cosmesis and were able to return to normal function without any residual symptoms. CONCLUSION: This pilot case series explored augmenting a flap reconstruction for complex PSD with advanced ECM graft materials, demonstrating that it may improve outcomes and minimise typical complications seen in flap closure, such as inflammation, infection, haematoma/seroma and hypoperfusion. Although the study had a limited number of participants, long-term outcomes were promising and suggest that further studies are warranted.

Craniometric and Volumetric Analysis of Posterior Vault Distraction Osteogenesis: 10 Year Update.

PURPOSE: The purpose of this study is to quantitatively establish the volumetric changes observed with posterior vault distraction osteogenesis in the anterior, middle, and posterior thirds of the cranial vault; characterize change in cranial length, width, and height, correlating these changes to demographic variables that may help identify why younger kids gain more volume; and describe the short-term position of the transport segment. METHODS: Multisuture craniosynostosis patients who underwent posterior vault distraction osteogenesis were retrospectively reviewed. Pediatric, dose-reduced, thin cut helically acquired head computed tomography scans were analyzed on Materialise Mimics v22 (Materialise, Ghent, Belgium). Pre and post-PVDO and "old" and "young" cohort were compared. RESULTS: Twenty-one patients met inclusion criteria. The change in cranial length was significantly less at a median of 14.9 mm [Interquartile range (IQR) 11.8, 31.6] compared to the X-ray measured AP distraction distance (30 mm [IQR 24, 33]; P < 0.001) and significantly less than the theoretically calculated distance (23 mm [IQR 19, 31]; P = 0.012). Median anterior cranial height was shorter post PVDO (82.9 mm, [IQR 64.8, 92.6] versus 78.7 mm [IQR 57.0, 88.7]; P = 0.030). The younger cohort saw a greater increase in total intracranial volume (median 335.1 mL [IQR 163.2, 452.3, median 37.1%] versus 144.6 mL [IQR 119.0, 184.8, median 12.0%]; P = 0.011). CONCLUSIONS: This is the first study to quantify volumetric changes to the anterior, middle, and posterior cranial vaults and demonstrates benefits of preforming PVDO at a younger age to help control turricephaly and produce greater percentage volumetric increases.

Submandibular Gland Excision in Pediatric Patients.

INTRODUCTION: Children who require submandibular gland excision for ptyalism often have multiple associated comorbidities, including neurodevelopmental disorders and respiratory risk factors. The purpose of this study is to utilize a large multicenter database to elucidate the perioperative profile of submandibular gland excision in children, with particular focus on children who require submandibular gland excision for ptyalism. METHODS: The American College of Surgeons National Surgical Quality Improvement Program Pediatric dataset was queried for submandibular gland excision performed from 2012 through 2018. Indications were subclassified based on International Classification of Disease (ICD)-9 and ICD-10 codes. Complications, readmissions, and reoperations were analyzed with appropriate statistics. RESULTS: During the study interval, 304 pediatric patients underwent submandibular gland excision, which was mostly performed for ptyalism (56.9%), followed by inflammatory conditions (20.7%). Patients requiring submandibular gland excision for ptyalism were significantly younger (P < 0.001) and underwent significantly longer procedures (P < 0.001). Ptyalism was associated with significantly higher related adverse events (P = 0.010), related readmission (P = 0.013), and medical complications (P = 0.013), which included a significantly higher risk of pneumonia (P = 0.050). Children with ptyalism had significantly higher rates of overall respiratory comorbidities (P < 0.001), including chronic lung disease (P < 0.001), supplemental oxygen support (P < 0.001), tracheostomy (P < 0.001), and ventilator dependence (P < 0.001). Patients undergoing submandibular gland excision for benign (P all ≥ 0.082) and malignant (P all ≥ 0.565) neoplasms did not have significantly higher rates of any indexed postoperative adverse event. CONCLUSIONS: Children requiring submandibular gland excision for ptyalism represent a unique cohort than those requiring excision for other indications, with significantly higher burden of preoperative risk factors, intraoperative durations, and postoperative adverse events.

Pediatric Orthognathic Surgery: National Analysis of Perioperative Complications.

BACKGROUND: Orthognathic surgery has traditionally been performed after skeletal maturity. Although these procedures are also being performed in children, the implications of earlier intervention and specific risk factors in this younger population remain unknown. METHODS: The American College of Surgeons National Surgical Quality Improvement Program Pediatric dataset was queried for orthognathic procedures performed in 2018. Complications, readmissions, and reoperations were analyzed with appropriate statistics. RESULTS: Overall adverse event rate after orthognathic surgery in pediatric patients was 7.8% (n = 22 of 281), which were associated with having any comorbidity (P < 0.001), overall respiratory comorbidities (P = 0.004), structural pulmonary abnormality (P < 0.001), developmental delay (P = 0.035), structural central nervous system abnormality (P < 0.001), and neuromuscular disorder (P = 0.035). Most common complications were excessive bleeding (2.5%), surgical site infection (1.1%), and pneumonia (0.7%). Orthognathic surgery in children below 6 years of age is associated with significantly increased adverse events (P < 0.001), including surgical site infection (P < 0.001), pneumonia (P = 0.022), readmission (P < 0.001), and reoperation (P < 0.001). Le Fort I osteotomies (P < 0.001) and bilateral sagittal split osteotomies (P = 0.009) took significantly longer for older patients in the years of permanent dentition than younger patients in the years of deciduous dentition. Single- and double-jaw procedures in pediatric patients have similarly low adverse events (P all ≥0.130). Interestingly, bilateral sagittal split osteotomies performed before 13.5 years of age were associated with a higher risk of adverse events (P = 0.012), such that these younger patients were 7.1 times more likely to experience adverse events if their procedure was performed earlier. CONCLUSIONS: Orthognathic surgery is relatively safe, but children in the years of deciduous dentition under 6 years of age have significantly increased risk of adverse events.

Unicoronal Craniosynostosis: Is There a Lateral Difference in Retinal Morphology?

BACKGROUND: Craniosynostosis is the premature fusion of cranial sutures in pediatric patients, which may lead to elevated intracranial pressure due to cerebro-cephalic disproportion between a growing brain and constricted skull. It is unknown whether this increased pressure is distributed equally throughout the cranial vault, or whether certain areas of the brain experience greater pressure at these regions of premature osseous fusion. METHODS: Optical coherence tomography (OCT) is a noninvasive modality for detecting elevated intracranial pressure. Optical coherence tomography was utilized to measure the peripapillary retinal nerve fiber layer (RNFL) thickness in patients undergoing surgical correction of craniosynostosis. Retinal nerve fiber layer in the eye ipsilateral to the unicoronal suture fusion was compared to the RNFL in the eye contralateral to the unicoronal suture fusion. RESULTS: During the study interval, 21 patients met inclusion criteria. Median age at operative intervention was 8.0 months, and 28.6% patients presented with left-sided unicoronal craniosynostosis, whereas 71.4% of patients presented with right-sided unicoronal craniosynostosis. Rather than universal increase on the affected side of coronal suture fusion, retinal nerve fiber layer thickness parameters showed a rotation phenomenon, such that the patterns of elevation had a 45° circumferential rotation in the direction of intorsion. CONCLUSIONS: The explanation for these results remains elusive, but they likely indicate either intracranial changes transmitted differentially to the peripapillary retina, or differing retinal morphology, between the ipsilateral and contralateral eyes in unicoronal craniosynostosis.
