Cultured Skin Autograft in Subtotal Pediatric Scalp Avulsion.

ABSTRACT: Pediatric scalp avulsions represent a reconstructive challenge because of the unique features of scalp tissue. When microsurgical reimplantation is not feasible, alternative approaches such as skin grafting, free flap transfer with latissimus flap, or tissue expansion are considered. Generally, there is no consensus regarding management of this trauma, and, oftentimes, multiple reconstructive techniques may be needed for definitive coverage. This case study describes the reconstruction of a pediatric subtotal scalp avulsion using a dermal regeneration template and novel autologous homologous skin construct. This case was complicated by the absence of original tissue for reimplantation, excessive size of the defect relative to body habitus, and family concerns for future hair-bearing function. The reconstruction successfully provided definitive coverage and significantly reduced the size of the donor site and associated compilations. However, the hair-bearing potential of the tissue has yet to be determined.

Ultra-Low-Dose Computed Tomography Protocol for Preoperative Evaluation in Children With Craniofacial Anomalies.

PURPOSE: Preoperative three-dimensional computed tomography is currently the gold standard imaging modality in patients with craniofacial anomalies. In these patients, bone structural evaluation is paramount for surgical planning and evaluation of brain parenchyma is often secondary. With the significant complexity of these patients, a majority of patients undergo multiple Computed Tomography (CT) studies from infancy into adulthood. This study presents an ultra-low-dose CT protocol that limits the radiation exposure per CT scan in patients with craniofacial anomalies. MATERIAL AND METHODS: A total of 200 consecutive patients who underwent head CT for preoperative evaluation of craniofacial anomalies at Tertiary Children's Hospital were included in the study. The kVp, (KiloVoltage Peak) mA (milliAnperage), CT dose index (CTDI), and dose-length product (DLP) were documented from the dose page. Patients were stratified based on age for determining age specific effective dose and for age matched comparison. The age specific effective dose was derived by using the established conversion factor as described in the paper. (1) Standard t test was performed to determine the statistical significance of radiation dose reduction. The Institutional Review Board approved the study and data was collected from 2012-2014. FINDINGS: Of the 200 patients assessed in our study, 90 patients had low-dose CT scans and 110 patients had ultra-low-dose CT scans of the head. All patients had diagnostic quality CT studies. The low-dose CT was performed at 120 kVp and 100 mA. The ultra-low-dose CT was performed at 80 kVp and fixed 80 mA. The minimum, maximum and mean effective dose before the introduction of the ultra-low-dose protocol was 0.8 mSv, 6.9 mSV and 2.82 mSv. The minimum, maximum and mean effective dose after the introduction of the ultra-low-dose protocol was 0.6 mSv, 3.8 mSV, and 1.37 mSv. The reduction in the effective radiation dose was statistically significant (standard t test; P = 0.0001). CONCLUSION: Compared to the regular low-dose protocol, the ultra-low-dose CT protocol provided appropriate diagnostic images with a significantly decreased radiation dose.

Serial Posterior Cranial Vault Distraction for the Treatment of Complex Craniosynostosis.

ABSTRACT: Posterior cranial vault distraction is an important modality in the management of craniosynostosis. This surgical technique increases intracranial volume and improves cranial aesthetics. A single procedure is often inadequate in patients with complex multisuture craniosynostosis, as some will go on to develop intracranial hypertension despite the operation. Considering the negative effects of intracranial hypertension, some patients may warrant 2 planned distractions to prevent this scenario from ever occurring. Three patients with complex multiple-suture synostosis and severe intracranial volume restriction (occipital frontal head circumferences [OFCs] <1st percentile) were treated with 2 planned serial posterior cranial vault distractions at the institution between 2013 and 2018. Demographics, intraoperative data, and postoperative distraction data were collected. The OFC was recorded pre- and postdistraction, at 3- and 6-month follow-up appointments. Patients had a corrected average age of 18 weeks at the time of their initial procedure. There was an average of 38 weeks between the end of consolidation and the time for their 2nd distraction procedure. There was an average age of 79 weeks at the time of the 2nd procedure. All patients had a substantial increase in OFC and improvement of the posterior calvarium shape. The average increase in OFC was 5.2 cm after first distraction and 4.3 cm after 2nd distraction. No postoperative complications were encountered. Planned serial posterior cranial vault distraction is a safe and effective strategy for increasing intracranial volume, improving aesthetic appearance, and preventing the consequences of intracranial hypertension in patients with multisuture craniosynostosis and severe intracranial volume restriction.

Modified Lefort Distraction Osteogenesis for the Treatment of Nager Syndrome-Associated Midface Hypoplasia: Technique and Review.

The surgical management of midface hypoplasia in the setting of Nager syndrome remains a significant challenge for craniofacial surgeons. This study describes a novel technique using distraction osteogenesis and modified osteotomies for the treatment of midface bony defects in an 11-year-old child with Nager syndrome.Presurgical 3-dimensional planning was performed to design the osteotomies and placement of distractors. The surgical approach required upper buccal sulcus and extended transconjunctival incisions only. Osteotomies were performed from the pyriform aperture through the orbit to include the lateral orbital wall, with bilateral osteotomy of the zygomas through the anterior arch via the transconjunctival incision. Distraction of the en bloc midface segment was successfully performed using external distractors. Bone grafting was not required. There were no complications.External distraction was well tolerated and there were no intraoperative or postoperative complications. The distractors were removed uneventfully after consolidation. The midface was successfully advanced without the need for bone grafting or bicoronal incision. The occlusal plane was leveled and the aesthetic appearance of the child was improved.Symmetrical midface hypoplasia in the context of Nager syndrome can be successfully corrected with en bloc distraction osteogenesis of the maxilla and bilateral zygomas through modified osteotomies that exclude the upper nasal pyramid. The approach is simplified and the need for bicoronal incision and bone grafting is mitigated in this technique, which the authors have named Lefort 2.5.

Protection of the Temporomandibular Joint During Syndromic Mandibular Distraction With a Novel Condylar Offloading Device.

Mandibular distraction for severe micrognathia in syndromic patients often leads to temporomandibular joint (TMJ) ankylosis, which requires further interventions to regain joint motion. The increased incidence of postdistraction ankylosis is likely related to increased prevalence of preoperative joint pathology in syndromic micrognathic patients. Previous studies have demonstrated that offloading the pressure on the condyle during the distraction process can prevent such TMJ pathology. In this article, the authors describe a successful new method for offloading the condyle to prevent postdistraction ankylosis using an external TMJ offloading device.

Creation of an Aesthetic Male Nipple Areolar Complex in Female-to-Male Transgender Chest Reconstruction.

BACKGROUND: Female-to-male chest wall reconstruction is becoming more common, but while there is a growing body of the literature describing technique and algorithms, little detail is written on methods for creating a male appearing nipple areolar complex (NAC) from a female NAC utilizing free nipple graft techniques. Incorrect positioning of the NAC on the chest wall and suboptimal shaping and sizing of the NAC are common pitfalls in male NAC creation. METHODS: With this paper, we present techniques for nipple grafting to achieve improved male appearing NACs, as well as a simple, reproducible method for appropriate placement of the NAC relative to the borders of the pectoralis muscle. To validate our technique, we performed photographic analysis of 64 NACs in 32 volunteers with BMI of 25 or less. RESULTS: The anatomic study determined the cis-male nipple to be positioned on average 2.5 cm medial to the lateral border of the pectoralis muscle and 2.4 cm above the inferior pectoralis insertion. This supports our surgical technique of positioning the NAC in relation to the pectoralis borders rather than previously advocated anatomic landmarks. We also present reliable techniques for creating a round or horizontally oval final NAC shape as well as a composite grafting technique for cases of large papillae. CONCLUSIONS: Our anatomic study supports placement of the male NAC relative to lateral and inferior borders of the pectoralis muscle. Nipple grafting techniques presented allow for a simple and reproducible method of creating an aesthetic male NAC shape in female-to-male transgender chest reconstruction.

Serial head circumference and neurodevelopmental screening after surgical correction for single- and multiple-suture craniosynostosis.

OBJECTIVE: To evaluate serial head circumference (HC) measurements and neurodevelopmental (ND) screening before and after surgical revision for craniosynostosis. DESIGN: Retrospective assessment. SETTING: Tertiary institutional. PATIENTS, PARTICIPANTS: All children treated with single-stage frontal-orbital advancement or total calvarial expansion for single-suture (SS) or multiple-suture (MS) craniosynostosis over a 7-year period. MAIN OUTCOME MEASURES: Changes in ND and HC were measured over postoperative visits after the primary surgery. More importantly, ND and HC changes were measured prerevision and postrevision. RESULTS: Of 183 patients undergoing primary surgery, complete records and adequate follow-up were available for 112 patients. The overall revision rate was 21% (n  =  23). Postrevision follow-up was adequate for 18 of the 23 revisions. After primary surgery, but prior to revision, children demonstrated a larger decline in HC (z-score, median  =  -1) along with higher ND findings (median  =  2) from one postoperative visit to the next than those who did not go on revision (HC z-score median  =  0, ND median  =  0). After revision, patients demonstrated a significant improvement in ND screening findings (median ΔND findings  =  -2) compared with prerevision ND (p < .001). Head circumference also significantly increased by a z-score of +1 postrevision (p  =  .001). CONCLUSIONS: Patients chosen for revision surgery display not only a larger decline in HC but also more ND findings prior to revision. Furthermore, surgical revision has a significant association with both improved ND screening and HC.

Expected Impact of the Pass/Fail Scoring System for USMLE Step 1 on the Plastic Surgery Residency Selection Process: A National Survey of Plastics Program Directors.

BACKGROUND:  Traditionally, the United States Medical Licensing Examination (USMLE) Step 1 3-digit score has been used as a metric to stratify plastic surgery residency candidates. The transition to a pass/fail exam may impact the manner in which integrated plastic surgery residency program directors (PS-RPD) evaluate candidates. It may also limit opportunities for applicants to differentiate themselves from their counterparts. METHODS: A 14-question survey was distributed via email to 76 PS-RPDs collected from the American Medical Association (AMA) residency program site, FRIEDA. It was sent three times from March 3 - March 14, 2020. McNemar tests were performed on the current metrics of evaluation in comparison to metrics expected to be used in the absence of a 3-digit Step 1 score, assuming a P < 0.05 level for statistical significance.  Results: Of the 76 integrated plastics programs surveyed, 24 PS-RPDs responded (31.6% response rate); 91.3% of PS-RPDs strongly disagree or disagree that Step 1 should be pass/fail; 78.3% of PS-RPDs strongly disagree or disagree that diversity will increase. The top five evaluation metrics PS-RPDs expect to utilize following the transition to pass/fail are: letters of recommendation (87.0%; CI 72% - 100%; p=0.500), Step 2 score (78.3%; CI 60% - 96%; p=0.001), research (56.5%; CI 35% - 78%; p=0.125), elective rotation (56.5%; CI 35% - 78%; p=1.000), and personal knowledge of the applicant (52.2%; CI 30% - 74%; p=0.500).  Conclusions: In the absence of a Step 1 score, PS-RPDs may require more holistic metric(s) to evaluate the best fit for their program. This study found that PS-RPDs expect their candidate evaluation process to remain highly similar with the only statistically significant change being an increased emphasis on the candidate's Step 2 score.

Will Residency Program Directors Look at My United States Medical Licensing Examination (USMLE) Step 1 Score During the 2022-2023 Application Cycle? A National Survey of Program Directors.

Background The 2022-2023 residency match cycle will be the first cycle that program directors will have to consider some applicants with a numerical United States Medical Licensing Examination (USMLE) Step 1 score while other applicants will only report pass/fail for USMLE Step 1. Previous studies have explored how USMLE Step 1 becoming pass/fail will alter the residency selection process, but it is not yet known when program directors from each specialty expect those changes to be implemented. Methods Residency program director's contact information was extracted from the American Medical Association (AMA) residency program site, Fellowship and Residency Electronic Interactive Database (FREIDA). Of the 5190 programs, 4877 were determined eligible for this study of which 1274 (26.8%) responded. Results Of the 1274 US residency program directors included in this survey, 77.0% do not intend to adjust their usage of USMLE Step 1 as a metric in candidate evaluation until the score is no longer reported. Conclusion Residency candidates applying during the upcoming cycle can expect the majority of residency programs will not significantly alter their previous utilization of an applicant's USMLE Step 1 score during the current 2022-2023 residency match cycle.

Management of Large Pediatric Wound Defects Using a Continuous External Tissue Expander.

Both internal and external tissue expanders take advantage of the innate adaptive mechanisms the skin exerts in response to mechanical tension, known as the stress-relaxation phenomenon. Internal tissue expander use is time-consuming and can be complicated by infection and extrusion. In this case series, continuous external tissue expanders used to manage large pediatric wounds were assessed. Fourteen patients (ages: 4 days to 17 years) with large wounds underwent continuous external tissue expansion intraoperatively. The success of wound closure was assessed. In addition, the size of the patient's wounds, duration of device application, and postoperative complications were evaluated. The continuous external tissue expander was applied to wound sizes ranging from 14.7 to 560 cm2 for 5 to 10 days until the wound was amenable for direct closure. In 11 of the 14 patients, delayed primary closure was achieved. The device significantly reduced the wound sizes of the remaining three cases (average 80% size reduction). There was no incidence of wound dehiscence or infection. This case series demonstrates the benefit of the continuous external tissue expansion in managing pediatric wounds that would not otherwise be amenable to primary closure. The method allows for timely closure with limited risk of infection or extrusion, and should be in the armamentarium of reconstructive plastic surgeons.

The Benefit of a Formal Plastic Surgery In-Service Conference.

INTRODUCTION: Annually, residents are expected to take an in-service examination to gauge their understanding of plastic surgery knowledge and prepare them for the American Board of Plastic Surgery written examination. In addition, in-service score are now being used as an assessment tool for fellowship applicants. Because of the breadth of Plastic Surgery material, it is difficult to prepare a resident for such a comprehensive examination. At the University of Utah, a weekly conference was instituted to help prepare residents for the in-service and board examination with the goal of improving scores. MATERIALS AND METHODS: A weekly 90min review conference was initiated at the University of Utah in an effort to improve in-service scores. Residents along with a member of the faculty reviewed old in-service examination questions and discussed the selected topics in depth. The residents' examination score averages per PGY level were compared from years before and after initiation of the conference. In addition, examination scores for each individual were compared before and after initiation of the conference. Paired t-test comparisons were performed to analyze the results. RESULTS: Statistically significant improvement in residents examination scores averages were observed from years before and after initiation of the conference after the second year of training (42% vs 62%, p = 0.03). Furthermore, examination scores for each individual obtained the years before and the year after initiation of the conference significantly improved (31% vs 71%, p = 0.01). When comparing individuals in years prior to implementation of the conference there was no statistically significant improvement from year to year. CONCLUSION: Implementation of a formal weekly in-service conference significantly improved performance on the in-service examination. Improvement was found when comparing between PGY training level after the second year of training and individually for residents. These results advocate for a focused educational conference for preparation for the in-service examination.
