The First Hybrid International Educational Comprehensive Cleft Care Workshop.

OBJECTIVE: Describe the first hybrid global simulation-based comprehensive cleft care workshop, evaluate impact on participants, and compare experiences based on in-person versus virtual attendance. DESIGN: Cross-sectional survey-based evaluation. SETTING: International comprehensive cleft care workshop. PARTICIPANTS: Total of 489 participants. INTERVENTIONS: Three-day simulation-based hybrid comprehensive cleft care workshop. MAIN OUTCOME MEASURES: Participant demographic data, perceived barriers and interventions needed for global comprehensive cleft care delivery, participant workshop satisfaction, and perceived short-term impact on practice stratified by in-person versus virtual attendance. RESULTS: The workshop included 489 participants from 5 continents. The response rate was 39.9%. Participants perceived financial factors (30.3%) the most significant barrier and improvement in training (39.8%) as the most important intervention to overcome barriers facing cleft care delivery in low to middle-income countries. All participants reported a high level of satisfaction with the workshop and a strong positive perceived short-term impact on their practice. Importantly, while this was true for both in-person and virtual attendees, in-person attendees reported a significantly higher satisfaction with the workshop (28.63 ± 3.08 vs 27.63 ± 3.93; P = .04) and perceived impact on their clinical practice (22.37 ± 3.42 vs 21.02 ± 3.45 P = .01). CONCLUSION: Hybrid simulation-based educational comprehensive cleft care workshops are overall well received by participants and have a positive perceived impact on their clinical practices. In-person attendance is associated with significantly higher satisfaction and perceived impact on practice. Considering that financial and health constraints may limit live meeting attendance, future efforts will focus on making in-person and virtual attendance more comparable.

The endocannabinoid system and retinoic acid signaling combine to influence bone growth.

Osteoporosis is an increasing burden on public health as the world-wide population ages and effective therapeutics are severely needed. Two pathways with high potential for osteoporosis treatment are the retinoic acid (RA) and endocannabinoid system (ECS) signaling pathways. We sought to elucidate the roles that these pathways play in bone development and maturation. Here, we use chemical treatments to modulate the RA and ECS pathways at distinct early, intermediate, and late times bone development in zebrafish. We further assessed osteoclast activity later in zebrafish and medaka. Finally, by combining sub-optimal doses of AR and ECS modulators, we show that enhancing RA signaling or reducing the ECS promote bone formation and decrease osteoclast abundance and activity. These data demonstrate that RA signaling and the ECS can be combined as sub-optimal doses to influence bone growth and may be key targets for potential therapeutics.

Simulation-Based Comprehensive Cleft Care Workshops: A Reproducible Model for Sustainable Education.

OBJECTIVE: Evaluate simulation-based comprehensive cleft care workshops as a reproducible model for education with sustained impact. DESIGN: Cross-sectional survey-based evaluation. SETTING: Simulation-based comprehensive cleft care workshop. PARTICIPANTS: Total of 180 participants. INTERVENTIONS: Three-day simulation-based comprehensive cleft care workshop. MAIN OUTCOME MEASURES: Number of workshop participants stratified by specialty, satisfaction with the workshop, satisfaction with simulation-based workshops as educational tools, impact on cleft surgery procedural confidence, short-term impact on clinical practice, medium-term impact on clinical practice. RESULTS: The workshop included 180 participants from 5 continents. The response rate was 54.5%, with participants reporting high satisfaction with all aspects of the workshop and with simulation-based workshops as educational tools. Participants reported a significant improvement in cleft lip (33.3 ± 5.7 vs 25.7 ± 7.6; P < .001) and palate (32.4 ± 7.1 vs 23.7 ± 6.6; P < .001) surgery procedural confidence following the simulation sessions. Participants also reported a positive short-term and medium-term impact on their clinical practices. CONCLUSION: Simulation-based comprehensive cleft care workshops are well received by participants, lead to improved cleft surgery procedural confidence, and have a sustained positive impact on participants' clinical practices. Future efforts should focus on evaluating and quantifying this perceived positive impact, as well reproducing these efforts in other areas of need.

Trends in Enteral Access Placement Among Patients With Oral Clefts: Evaluation of 46 617 Patient Admissions.

OBJECTIVE: It is well known that patients with oral clefts have challenges with feeding. Enteral feeding access, in the form of gastrostomy, is often utilized to supplement or replace oral intake. Although commonly performed, these procedures have reported complication rates as high as 83%. We intend to discover rates of enteral access in patients with oral clefts and report-related outcomes. DESIGN: The Healthcare Cost Utilization Project Kids' Inpatient Database from 2000 to 2012 was analyzed using patients with oral clefts and enteral access procedures. The χ2 test was used for univariate analyses of proportions, and linear regression was used to analyze trends. Multivariate logistic regression was used to analyze odds ratios. RESULTS: Of the 46 617 patient admissions included, 14.6% had isolated cleft lip (CL), 51.7% cleft lip and palate (CLP), and 43.7% isolated cleft palate. The rates of enteral access in the oral cleft population increased from 3.7% in 2000 to 5.8% in 2012 ( P < .001). Increased rates were identified in patients with ( P = .019) and without ( P < .001) complex conditions. A significant increase in the rate of enteral access was seen in patients with CLP ( P < .001) and isolated cleft palate ( P < .001). No difference was seen in the isolated CL group ( P = .096). Patients with complex conditions were at a 4.4-fold increased risk and those admitted to urban, teaching hospitals were at a 4.7-fold risk of enteral access placement. CONCLUSIONS: The rates for enteral feeding access increased significantly from 2000 to 2012. The reasons for the increased incidence are unclear. Invasive enteral access procedures have been shown to have a multitude of complications. Careful patient selection should be done before placement of invasive enteral access.

A Novel Treatment of Nasal Stenosis Using Steel Gauging Earrings.

Nasal stenosis is an uncommon and challenging deformity. Most common etiologies for nasal stenosis include congenital, iatrogenic, trauma, and infection. Repair techniques typically include tissue replacement with grafts or flaps with subsequent stent placement. These procedures often require general anesthesia and carry high rates of restenosis. We describe a case of a 10-year-old girl with Teebi syndrome and iatrogenic nasal stenosis who underwent successful nasal dilation with inexpensive, minimally invasive steel gauge earrings.

The Directive Growth Approach for Nonsyndromic, Unicoronal Craniosynostosis: Patient and Clinical Outcomes.

Deformities of the cranium in patients with nonsyndromic single-suture synostosis occur because of growth restriction at fused sutures and growth over compensation at normal sutures. Traditional surgery includes ostectomies of the synostotic suture to release these restricted areas and osteotomies to enable immediate cranial remodeling. In the process of reshaping the cranium, traditional approaches usually involve obliteration of both the normal functioning suture and the pathologic suture. The directive growth approach (DGA) is a new, simpler, more natural way to repair deformities caused by single-suture cranial synostosis. The DGA works by reversing the original deforming forces by temporarily restricting growth in areas of over compensation and forcing growth in areas of previous synostotic restriction. Most importantly, it preserves a normal functioning suture to allow for improved future cranial growth. Eighteen consecutive nonsyndromic patients with unilateral coronal synostosis were used to illustrate the efficacy of the DGA. Ten patients who underwent DGA treatment were compared with a control group of 8 patients treated with traditional frontal orbital advancement. Postoperative three-dimensional computed tomography (CT) comparison measurements were taken, including bilateral vertical and transverse orbital dimensions, lateral orbital rim to external auditory canal, and forehead measurements from the superior aspect of the orbital rim to the pituitary fossa. The traditional treatment group showed absence of the coronal sutures bilaterally on long-term CT scans. The DGA group showed normal coronal sutures on the unaffected sides. Postoperative CT measurements showed no statistical difference between the 2 techniques (P < 0.05).

The Effects of Motorcycle Helmet Legislation on Craniomaxillofacial Injuries.

BACKGROUND: Motorcycle helmet legislation has been a contentious topic for over a half-century. Benefits of helmet use in motorcycle trauma patients are well documented. In 2012, Michigan repealed its universal motorcycle helmet law in favor of a partial helmet law. The authors describe the early clinical effects on facial injuries throughout Michigan. METHODS: Retrospective data from the Michigan Trauma Quality Improvement Program trauma database were evaluated. Included were 4643 motorcycle trauma patients presenting to 29 Level I and II trauma centers throughout Michigan 3 years before and after the law repeal (2009 to 2014). Demographics, external cause of injury codes, International Classification of Diseases, Ninth Revision diagnosis codes, and injury details were gathered. RESULTS: The proportion of unhelmeted trauma patients increased from 20 percent to 44 percent. Compared with helmeted trauma patients, unhelmeted patients were nearly twice as likely to sustain craniomaxillofacial injuries (relative risk, 1.90), including fractures (relative risk, 2.02) and soft-tissue injuries (relative risk, 1.94). Unhelmeted patients had a lower Glasgow Coma Scale score and higher Injury Severity Scores. Patients presenting after helmet law repeal were more likely to sustain craniomaxillofacial injuries (relative risk, 1.46), including fractures (relative risk, 1.28) and soft-tissue injuries (relative risk, 1.56). No significant differences were observed for age, sex, Injury Severity Score, or Glasgow Coma Scale score (p > 0.05). CONCLUSIONS: This study highlights the significant negative impact of relaxed motorcycle helmet laws leading to an increase in craniomaxillofacial injuries. The authors urge state and national legislators to reestablish universal motorcycle helmet laws.

Repair of Oropharyngeal Stenosis With Bilateral Buccal Myomucosal Flaps.

Oropharyngeal stenosis (OPS) is a rare postoperative complication of adenotonsillectomy that can be a source of considerable patient distress and morbidity. Circumferential scarring of the soft palate and tonsillar pillars leads to narrowing of the oropharyngeal aperture. This case report describes the novel use of bilateral buccal myomucosal flaps for the repair of postoperative OPS in a 20-year-old woman presenting with dysphagia, odynophagia, dyspnea, and intermittent hypernasal speech. Postoperatively, the patient noted immediate improvement of her symptoms. At 1-month follow-up, she noted complete resolution of her symptoms with no dysphagia, nasal regurgitation, speaking difficulty, dyspnea, or gagging. The buccal flaps were well healed and completely intact, maintaining appropriate height of the tonsillar pillars. The buccal myomucosal flap is an effective tool for numerous palatal and oropharyngeal abnormalities and, as described in this case study, is a reliable, safe, and effective technique that can be considered for the reconstruction of postsurgical OPS.

The Double Opposing Z-Plasty Plus or Minus Buccal Flap Approach for Repair of Cleft Palate: A Review of 505 Consecutive Cases.

BACKGROUND: Standard methods of cleft palate repair rely on existing palatal tissue to achieve closure. These procedures often require relaxing incisions, causing scars and growth restriction, and may result in insufficient palatal length and suboptimal positioning of the velar musculature. The Furlow double opposing Z-plasty improves palatal length and repositions the velar musculature; however, relaxing incisions may still be needed. The addition of buccal flaps to the Furlow repair obviates the need for relaxing incisions and allows the Furlow repair to be used in wide clefts. METHODS: A retrospective review was performed on 505 patients; all patients were treated with the double opposing Z-plasty plus or minus buccal flap approach. Outcomes included nasal resonance, secondary speech surgery, and postoperative complications. A comparison was made between patients treated with double opposing Z-plasty alone and those treated with double opposing Z-plasty plus buccal flaps. RESULTS: The average nasal resonance score was 1.38 and was equivalent in both the double opposing Z-plasty alone and with buccal flap groups, despite significantly more wide clefts in the buccal flap group (56 percent versus 8 percent). The secondary surgery rate for velopharyngeal insufficiency was 6.6 percent and the fistula rate was 6.1 percent. The large fistula rate (>2 mm) was 2.7 percent. CONCLUSIONS: The double opposing Z-plasty plus or minus buccal flap approach is a useful alternative to standard palate repairs. Speech outcomes were excellent, even in wider clefts, and postoperative complications were minimal. Buccal flaps allow the benefits of the Furlow repair to be applied to any size cleft, without the need for relaxing incisions. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Reduction of post-surgical scarring with the use of ablative fractional CO2 lasers: A pilot study using a porcine model.

BACKGROUND AND OBJECTIVE: Wound healing inevitably leads to scarring, which leads to functional and cosmetic defects. It is the goal of this study to investigate the immediate use of ablative fractional CO2 lasers to reduce post-operative scarring secondary to surgical wounds. STUDY DESIGN/MATERIALS AND METHODS: In this prospective controlled study, 20 surgical incisions were created on each of three pigs. Fifteen of the incisions were treated with an ablative fractional CO2 laser at one of three laser settings. The remaining five incisions served as a control. Punch biopsies were taken post-operatively over time. Digital photographs were taken of each incisional scar at each time period. Blinded evaluators used a previously verified scoring system to score photographs of the incisional scars taken at the 6 month time period. RESULTS: With regards to the comparison between the three individual laser treatment groups and the control, there were no statistically significant effects for treatment (P = 0.40), time (P = 0.48), or for the interaction of time and treatment (P = 0.57). With regards to the visual assessment tool, there were no statistically significant differences between treatments for Overall Appearance (P = 0.21) or for Total Score (P = 0.24). CONCLUSIONS: In the limited setting of this pilot study, treatment of surgical incisions with ablative fractional CO2 lasers does not significantly lessen scar formation. In addition, photographic analysis was not able to demonstrate a significant difference. Future studies on this topic will need a larger sample size to better answer whether a statistically significant difference may exist. Lasers Surg.

Treatment of cranial synostosis: the directive growth approach.

Reconstruction for single sutural synostosis typically involves cranial reshaping to correct for compensatory growth changes. Current remodeling techniques involve obliteration of both pathologic and normal sutures. Presented here is a case report describing a new approach to the treatment of single cranial synostosis. The concept involves excision of the offending suture and transient plating of the remaining functional sutures. Compensatory sutures are then allowed to direct the growth forces to the area of the synostosis, leading to the reversal of the compensatory shape deformity. This more natural approach leaves functioning sutures intact and allows for their active participation in the reshaping process.

A novel technique for performing a tongue-lip adhesion-the tongue suspension technique.

BACKGROUND: The tongue-lip adhesion has undergone several modifications in an attempt to reduce surgical complications and failure rates. Current techniques rely on the use of a button at the tongue base for suspension, which raises concerns about possible aspiration and interference with oral motor function and bottle-feeding. A new technique for tongue-lip adhesion is proposed that adds a tongue suspension to the standard surgical adhesion. METHODS: A total of 22 patients with Pierre Robin sequence who received a tongue-lip adhesion via a tongue suspension technique were reviewed. The surgical technique differs from the standard surgical approach by the use of a suture weave across the base of the tongue instead of a standard button to suspend the tongue anteriorly. RESULTS: Average age at the time of tongue-lip adhesion was 13.9 days, with a mean operative time of 88.8 minutes. A marked improvement in postoperative oxygenation was seen in the majority of patients. One dehiscence occurred secondary to a traumatic postoperative extubation, eventually requiring a tracheostomy for subglottic stenosis. CONCLUSION: A technical innovation for performing a tongue-lip adhesion using a tongue suspension in conjunction with a standard transverse adhesion of the lip is described. The advantage of the tongue-lip adhesion with suspension includes immediate postoperative extubation, as well as removal of concerns regarding button aspiration and possible interference in early developmental oral motor function and bottle-feeding. This technique is reproducible, expanding the craniofacial surgeon's armamentarium for the management of difficult airways in Pierre Robin sequence.

Mimix hydroxyapatite cement use in the reconstruction of the craniofacial skeleton.

Reconstruction of the craniofacial skeleton has undergone a significant evolution during the past century. Initially, the use of autogenous bone grafts from various sites was the criterion standard. However, owing to donor site morbidity and lack of sufficient bone for large defects, surgeons have relied on various bone substitutes. Hydroxyapatite (HA) has served as an alternative to autogenous grafts, but questions regarding biocompatibility, risk of infection, and slow set times have hampered its acceptance. This article serves as a review of a single surgeon's experience using HA in the craniofacial skeleton. Eighteen patients receiving HA between March 2000 and November 2006 were observed. Sixteen underwent recontouring of skull-based bone defects, and 2 underwent recontouring for nasal and alveolar defects. The mean amount of HA used in each patient was 30.2 g. For large contour irregularities, the maximum thickness of HA used was 8 mm. The size of bone defects ameliorated averaged 4.8 cm(2). Complications occurred in 3 (16.7%) of 18 patients and included scalp hematoma and superficial cellulitis. In addition, 1 patient developed a facial abscess after placement along the alveolar floor, which necessitated removal. Hydroxyapatite represents a viable alternative to autogenous bone grafts when used in the correct manner. Hydroxyapatite should be used only for smaller defects or used in conjunction with absorbable plates when attempting to fill larger defects. Use of HA for nasal piriform augmentation or alveolar bone grafting should not be considered owing to problems with late infections.

The double-opposing buccal flap procedure for palatal lengthening.

BACKGROUND: Velopharyngeal dysfunction has been treated with either a pharyngeal flap or sphincteroplasty with varying degrees of success. Both of these entities have their own series of problems, with sleep apnea and nasal mucous flow disruptions at the forefront. The purpose of this study was to review the senior author's (R.J.M.) experience performing the double-opposing buccal flap for palatal lengthening. METHODS: All patients who were treated with double-opposing buccal flaps between October of 1994 and July of 2007 were reviewed. These patients presented with varying degrees of velopharyngeal dysfunction showing some degree of velar movement at the time of surgery. Preoperative and postoperative speech results were reviewed for comparison. RESULTS: Twenty-seven patients underwent palatal lengthening, with an average length of follow-up of 58 months. Distal flap necrosis occurred in two patients. The level of intelligibility (65.4 percent versus 95.5 percent) and resonance (moderately hypernasal versus normal resonance) improved significantly postoperatively (p < 0.0001). Only one patient required the addition of a pharyngeal flap for persistent velopharyngeal dysfunction, and there were no postoperative issues with sleep apnea. CONCLUSIONS: The double-opposing buccal flap is an effective technique for lengthening the palate, improving speech, and decreasing the risks of postoperative sleep apnea. All patients experienced a dramatic improvement in their resonance and intelligibility. This technique appears most effective in patients with intact velar movement who demonstrate a small to moderate posterior velar gap. The double-opposing buccal flap is a useful means of treating velopharyngeal dysfunction, thus serving as an adjunct when improving pharyngeal closure.
