Management of an open nasofrontal encephalocele during the first day of life.

Nasofrontal encephaloceles are extremely rare craniofacial defects that present with herniation of cerebral tissue through the junction of the frontal and nasal bones. They often have a cutaneous covering which allows management to be delayed until early infancy, decreasing the risks of anesthesia and acute blood loss. Further bone development also facilitates cranial remodeling. Encephaloceles with a compromised cutaneous envelope pose an imminent threat to life due to the risk of meningitis, necessitating surgical repair in the first days of life. This report presents a patient born with an open nasofrontal encephalocele that underwent encephalocele excision, dural repair, and cranial remodeling on the first day of life. Anterior encephaloceles represent a spectrum of uncommon craniofacial dysraphias. Given the rarity of these diseases, it is important to understand their many presentations and the treatment options that exist for each. When the cutaneous covering of the encephalocele is compromised, surgical correction must be undertaken urgently to mitigate the mortality associated with neonatal meningitis. This represents the first report of an open nasofrontal encephalocele managed in the first day of life. A multidisciplinary surgical approach involving the neurosurgical and craniofacial surgical teams is paramount to the treatment and survival of such complicated patients.

Characteristics of Lower Extremity Infection Rates Following Mohs Micrographic Surgery.

BACKGROUND: Surgical site infection (SSI) is the most common complication for Mohs micrographic surgery (MMS). Lower extremity surgical sites are at an increased risk for developing SSI. OBJECTIVE: This study aimed to evaluate lower extremity SSI rates post-MMS based on closure type and antibiotic usage. MATERIALS AND METHODS: A retrospective review was performed of all lower extremity MMS cases from 2011 to 2016 at Vanderbilt University Medical Center. Patient history, surgical details, and follow-up appointments were reviewed. RESULTS: Six hundred twenty MMS lower extremity surgeries were eligible. Review identified an overall lower extremity SSI rate of 7.4%. Infection rates were significantly increased in wound closed by flaps/grafts (p < .001). Although wound size and preoperative antibiotic prophylaxis were initially associated with increased infection rate (p = .03, p = .015), the associations were fully attenuated when adjusting for closure type. CONCLUSION: More complicated repair techniques (flap/graft) for larger wound sizes contribute to increased SSI risk among lower extremity MMS cases. Providers can use this information to guide antibiotic prophylaxis.

Resorbable Versus Titanium Hardware for Rigid Fixation of Pediatric Upper and Midfacial Fractures: Which Carries a Lower Risk Profile?

PURPOSE: Titanium associated risks have led to interest in resorbable hardware for open reduction and internal fixation (ORIF) of pediatric facial fractures. This study aims to systematically review and compare the outcomes of titanium/resorbable hardware used for ORIF of upper/midfacial fractures to determine which hardware carries a higher complication rate in the pediatric patient. METHODS: Studies published between 1990 and 2020 on the ORIF of pediatric upper/midfacial fractures were systematically reviewed. A retrospective institutional review was also conducted, and both arms were compiled for final analysis. The primary predictor value was the type of hardware used and the primary outcome was the presence of a complication. Fisher's exact test and 2-proportion 2-tailed z-test calculations were used to determine statistical significance, which was defined as a P value < .05. The low quality of published evidence precluded meta-analysis. RESULTS: Systematic review of 23 studies identified 659 patients, and 77 patients were identified in the institutional review. A total of 736 patients (299 resorbable, 437 titanium) were included in the final analysis. Total complication rate was 22.8%. The titanium group had a higher complication rate (27 vs 16.7%; P < .01), and more often underwent elective hardware removal (87.3 vs 0%, P < .01). In each hardware subgroup, the incidence of complications was analyzed by fracture site. In the titanium group, complication incidence was higher when treating maxillary fractures (32.8 vs 22.9%, P = .03). When comparing the 2 hardware groups by fracture site, maxillary fractures had a higher rate of complications when treated by titanium hardware compared with resorbable hardware (32.8 vs 18%, P < .01). CONCLUSIONS: Upper/midfacial pediatric fractures requiring ORIF, especially maxillary fractures, may be best treated with resorbable hardware. Additional hardware-specific outcomes data is encouraged.

Bannayan-Riley-Ruvalcaba syndrome with gingival hyperpigmentation and facial papules.

One of the distinctive cutaneous manifestations of Bannayan-Riley-Ruvalcaba syndrome (BRRS), a PTEN hamartoma tumor syndrome, is penile pigmented macules. We present a 13-year-old boy with gingival hyperpigmentation along with facial and ear angiofibromas in the context of a BRRS-concordant phenotype and PTEN hamartoma tumor syndrome genotype. To our knowledge, these two findings have not been previously reported with BRRS and may expand the known phenotype of this disorder.

The Paramedian Forehead Flap: A Retrospective Clinical Model for Understanding the Connection Between Supraorbital and Supratrochlear Nerve Pathology and Headaches.

Background: In the later stages of a paramedian forehead flap (PMFF) surgery, the supratrochlear (STN) and branches of the supraorbital nerve (SON) are transected during flap inset above the supraorbital rim. This can lead to either a nerve release if the compression point was previously distal to the transection point or a new nerve compression through neuroma or scar tissue formation. We inferred that PMFF could be a model for understanding the correlation between STN/SON pathology and migraines headaches (MH). We hypothesized that patients undergoing PMFF would experience either a change in severity or an onset of a new headache (HA) or MH. Methods: One hundred ninety-nine patients who underwent a PMFF at a tertiary medical centre were identified and contacted by phone. Patients were asked about the presence of MH or HA before and after the procedure. If a patient reported a perioperative history of MH/HA, their pre- and postoperative MH/HA characteristics were recorded. Results: Of the 199 patients contacted, 74 reported no perioperative HA/MH history and 14 reported a perioperative history of HA/MH. Of these 14 patients, 5 had stable HA/MH pre- and post-surgery, and 9 reported a change in HA/MH post-surgery. In this subset of 9 patients, 3 reported change in HA/MH quality post-surgery, 1 reported HA/MH resolution post-surgery, and 5 reported new onset HA/MH post-surgery. Conclusion: Sixty-four percent of patients with perioperative HA/MH experienced a change in headache quality following surgery. These results suggest a potential connection between SON and STN pathology and HA/MH pathophysiology; further work is warranted.

Historique: Dans les dernières phases de l'opération du lambeau frontal paramédian (LFPM), le nerf supratrochléaire (NST) et les rameaux du nerf supraorbital (NSO) sont sectionnés pour installer le lambeau au-dessus de l'arcade sourcilière. Cette intervention peut libérer le nerf si le point de compression se trouvait auparavant dans la partie distale de l'incision ou provoquer une nouvelle compression nerveuse par la formation d'un névrome ou de tissu cicatriciel. Les chercheurs ont présumé que le LFPM pouvait servir de modèle pour comprendre la corrélation entre la pathologie du NST ou du NSO et les migraines. Les chercheurs ont postulé que les patients qui se font greffer un LFPM présenteraient soit un changement de la gravité de leurs migraines ou de leurs céphalées ou de nouvelles migraines ou céphalées. Méthodologie: Les chercheurs ont communiqué par téléphone avec 191 patients qui se sont fait greffer un LFPM dans un centre de soins tertiaires. Ils leur ont demandé s'ils souffraient de migraines ou de céphalées avant et après l'intervention. Si le patient déclarait des antécédents périopératoires de migraines ou de céphalées, les chercheurs en consignaient les caractéristiques. Résultats: Des 199 patients, 74 n'ont déclaré aucun antécédent de migraines ou de céphalées, mais 14 ont signalé une histoire périopératoire de ces symptômes. De ces 14 patients, cinq présentaient une migraine ou une céphalée avant et après l'opération et neuf, un changement à ces manifestations. Dans ce sous-groupe de neuf patients, trois ont déclaré un changement de la qualité des migraines et des céphalées après l'opération, un en a signalé la résolution après l'opération et cinq, l'apparition après l'opération. Conclusion: Au total, 64% des patients ayant des migraines et des céphalées ont ressenti un changement à la qualité de leurs symptômes après l'opération. Ces résultats laissent croire à un lien potentiel entre la pathologie du NSO et du NST et la physiopathologie des migraines et des céphalées. D'autres travaux s'imposent sur le sujet.

Resorbable Versus Titanium Rigid Fixation for Pediatric Mandibular Fractures: A Systematic Review, Institutional Experience and Comparative Analysis.

Study Design: Pediatric mandible fractures mandate special consideration because of unerupted teeth, mixed dentition, facial growth and the inability to tolerate maxillomandibular fixation. No consensus exists as to whether resorbable or titanium plating systems are superior with regards to clinical outcomes. Objective: This study aims to systematically review and compare the outcomes of both material types in the treatment of pediatric mandible fractures. Methods: After PROSPERO registration, studies from 1990-2020 publishing on outcomes of ORIF of pediatric mandible fractures were systematically reviewed according to PRISMA guidelines. An additional retrospective review was conducted at a pediatric level 1 trauma center. Results: 1,144 patients met inclusion criteria (30.5% resorbable vs. 69.5% titanium). Total complication rate was 13%, and 10% required a second, unplanned operation. Complication rates in the titanium and resorbable groups were not significantly different (14% vs. 10%; P = 0.07), and titanium hardware was more frequently removed on an elective basis (P < 0.001). Condylar/sub-condylar fractures were more often treated with resorbable hardware (P = 0.01); whereas angle fractures were more often treated with titanium hardware (P < 0.001). Within both cohorts, fracture type did not increase the risk of complications, and comparison between groups by anatomic level did not demonstrate any significant difference in complications. Conclusions: Pediatric mandible fractures requiring ORIF are rare, and hardware-specific outcomes data is scarce. This study suggests that titanium and resorbable plating systems are equally safe, but titanium hardware often requires surgical removal. Surgical approach should be tailored by fracture anatomy, age-related concerns and surgeon preference.
