Surgical treatment and outcomes of fibrous dysplasia (FD) in pediatric patients are areas that have not been fully studied. The authors completed a retrospective review of 20 patients who had at least one surgery for craniofacial fibrous dysplasia before 18 years of age. Surgeries were categorized into 3 groups: bone contouring only; removal of the involved bone, contouring, and replacement of the contoured bone; or en bloc resection of the involved bone and reconstruction with an alloplastic material, bone allograft, or bone autograft obtained from non-involved sites. A total of 36 distinct surgical procedures were performed in 20 patients, with a mean number of 1.9 surgeries/patient (range 1–5). The maxilla was both the bone that was most commonly affected and most commonly operated on. The most common surgical indication was visible or palpable growth in 63.9% of cases. Bone contouring only was the initial surgery in 15 patients, of whom 9 patients (55.6%) had continued bone growth requiring subsequent surgeries. Removal, contouring, and replacement wasthe initial surgery in 1 patient, who required a secondary surgery. Four patients, all with monostotic calvarial disease, initially had an en bloc resection and reconstruction; none had recurrence. Patients with subsequent surgeries had a mean time to operation of 3.7 years (range 0.24–9.8). The recurrence rate and need for secondary surgical procedures were relatively high in patients who had bone contouring only. These patients tended to be patients with facial bone involvement more than calvarial involvement.

Background The management and use of antibiotics in pediatric ear lacerations lacks standardization. This study sought to provide a comprehensive review of these injuries and assess the impact of administering perioperative antibiotics on the incidence of infections after repair. Methods Retrospective review of all pediatric ear lacerations treated at our institution's emergency department (ED) between 1998 and 2024. Results A total of 246 patients (177 boys) were included. Patients aged 0–6 years were most affected (n = 117, 47.6%), with the peak between 2–5 years old (n = 78, 31.7%). Most lacerations were superficial (n = 145, 58.9%), followed by intermediate (n = 62, 25.2%), full thickness (n = 34, 13.9%), and split earlobe defects (n = 5, 2%). Most of the patients (n = 110, 54.7%) were managed by emergency medicine providers. Plastic and reconstructive surgery (n = 34, 16.9%) and otorhinolaryngology (n = 32, 15.9%) consultations were obtained when the lacerations affected cartilage (P < 0.001). Surgical repair included primary closure in 203 (82.5%), with 179 (88.2%) performed under local/topical anesthesia in the ED. Of patients with cartilage lacerations (n = 61), 48 had cartilage repair. Eight patients had preoperative intravenous antibiotics, while 105 (42.7%) received postoperative prophylactic oral antibiotics. Among those with intermediate and full-thickness injuries (n = 96), 67.7% were discharged on prophylactic oral antibiotics. Only 1 case of surgical site infection occurred in a patient with a superficial laceration. Conclusions Pediatric ear lacerations mostly affect boys aged 2–5 years and are usually repaired under local anesthesia in the ED. The incidence of infection is low, and the routine prescription of prophylactic oral antibiotics appears to have a limited impact on the overall incidence of surgical site infection. Further studies are needed to validate these findings.

Background: Despite increased adoption of virtual surgical planning (VSP) in various craniofacial indications, the incorporation of VSP/3DP into facial trauma care remains limited. Therefore, Expedited Preoperative Point of Care for Fracture Reduction to Normalized Anatomy and 3DP to Improve Surgical Outcomes (EPPOCRATIS) was introduced in 2021. This study evaluates our experience with EPPORATIS in craniomaxillofacial trauma over 10 years. Methods: A retrospective review of patients who underwent facial trauma repair between September 2014 and September 2024 was conducted. For each VSP/3DP case, a patient with similar facial trauma patterns, who was treated without VSP, was selected. Evaluation metrics included operative time, blood loss, length of stay, complication rates, and fracture reduction accuracy through 3D heatmap analyses. Operative metrics were normalized by implant (i.e., fracture plates and screws) count to account for fracture complexity. A value of p < 0.05 was deemed statistically significant. Results: The VSP group presented with more complex injuries and higher involvement of various surgical specialties (p < 0.5) and demonstrated longer operative times (p < 0.03). Although the difference was not statistically significant (p = 0.4), when adjusted for implant count, the VSP group had shorter operative times (median: 15.4 vs. 19.3 min/implant) and reduced blood loss compared to non-VSP cases (median: 3.4 mL/implant vs. 4.2 mL/implant). Complications, revision rates, and length of stay showed no significant differences. Conclusions: The use of VSP/3DP (EPPOCRATIS) in craniomaxillofacial trauma reconstruction demonstrated operative efficiency and accurate fracture reduction in complex cases. Further studies are needed to examine the feasibility and cost-effectiveness of point-of-care VSP/3DP in trauma centers.

Background: Controversy exists around the optimal timing of resection of nevus sebaceous (NS). The authors aim to determine optimal timing of NS resection and identify predictors of surgical outcomes and secondary intralesional neoplasms. Methods: Retrospective chart review of all patients with biopsy-proven NS diagnosis treated at the authors' institution between 1987 and 2024. Results: A total of 632 patients (317 females) underwent biopsy at a median age of 17 (interquartile range 11.7–36.9) years. Benign secondary intralesional neoplasms were found in 67 (10.6%) patients, with syringocystadenoma papilliferum being the most common. Malignant secondary intralesional neoplasms were diagnosed in 62 (9.8%) patients, with basal cell carcinoma being the most common. The incidence of secondary intralesional neoplasms was 3.9%, 24.4%, 36.05%, and 54%, in patients aged 0 to 20, 20 to 40, 40 to 60, and 60 to 80 years, respectively (P<0.001). Age and NS area were associated with an increased risk of developing benign and malignant intralesional neoplasms (P=0.01). Younger patients were more likely to need general anesthesia for excision (median age 10.42 versus 17 years, P<0.001). Surgical complications occurred in 10 cases, and 6 patients required unanticipated revision surgery. The risk of developing secondary intralesional neoplasms was similar across different NS anatomic regions (log-rank, P=0.09). Conclusion: Surgical excision of NS is safe and has an acceptable risk profile. The findings of this study support our historic practice of NS excision before puberty (before the accelerated growth phase) to reduce the risk of developing secondary intralesional neoplasms.

Objective: The pattern, rate, and natural history of bone flap resorption following cranioplasty with frozen, autologous bone flap has not been fully defined. The authors sought to quantify the progression and natural history of bone flap resorption. Methods: Patients who had craniectomy and delayed cranioplasty with stored, frozen bone flap between 2012 and 2022 were included in this study. Results: Ninety patients (63% male) were included, with a median age of 44.8 years (range: 4.2–84.4 y) at the time of autologous bone flap cranioplasty. Delayed, autologous cranioplasty occurred at a median time of 29.5 days (range: 2 d–10 y) from the index craniectomy. The median follow-up was 16.6 months (range: 3.4–85.4 mo). Radiographically quantifiable bone flap resorption occurred in 50 patients (56%). During the follow-up, the average percentage volume loss was 17%, with a nonlinear pattern of resorption. Following delayed, autologous cranioplasty, 11 patients had clinically significant bone flap resorption requiring secondary alloplastic cranioplasty at a median time of 13.8 months (range: 5.9–57.2 mo), with a mean percentage volume loss of 61%. Younger age was a risk factor for bone flap resorption (P < 0.05), whereas active smoking, presence of comorbidities, and number of days of bone flap storage were not risk factors for bone flap resorption. Penalized B-spline regression analysis showed that bone flap resorption followed a nonlinear pattern. Conclusion: Radiographically quantifiable bone flap resorption occurred in about 56% of patients following delayed autologous cranioplasty. Resorption followed a non-linear pattern. Young age is a risk factor for bone flap resorption.

Purpose: To review cases of lateral brow dermoid cysts and gain insight into the utility of preoperative imaging, incidence of intraorbital extension, and recurrence rate. Methods: This is a retrospective study of all patients who underwent excision of lateral brow dermoid cysts at the authors' academic center over a 37-year period. Results: A total of 136 patients were included. The median age at presentation was 5.6 months [interquartile range (IQR) 3–16.5], and the median age at removal was 1.5 years (IQR 0.9–3.4). Preoperative imaging was performed in 44 patients. Intraorbital communication was predicted in 4 patients who underwent imaging and confirmed in 6 patients (4.4%) intraoperatively. Superficial dermoids were the most common depth (n=79, 58.1%), followed by periosteal (n=37, 27.2%) and intraosseous (n=14, 10.3%). Two patients (1.4%) presented with postoperative hematoma that required surgical evacuation. Recurrence was seen in 2 patients (1.4%). Among those who completed a follow-up, the median follow-up time was 1 month (IQR 0.44–5.8 months). Conclusion: The authors' study revealed that the majority of lateral brow dermoid cysts are either superficial or involve the periosteum, with orbital involvement being rare. None of our patients demonstrated intracranial communication. Imaging did not seem to add clinical value in patients for whom there was no clinical suspicion for the involvement of the deeper tissues, so careful consideration of ordering preoperative imaging would help decrease health care costs and avoid radiation exposure, which is particularly concerning for pediatric patients. The recurrence rate of lateral brow dermoid cyst seems to be low but studies with longer follow-ups are needed.

Objective Dermoid cyst (DC) is a congenital cyst with the potential to have intracranial extension (ICE). This study aims to evaluate the imaging yield and surgical outcomes of nasal, medial brow, forehead, and scalp DCs. Design Retrospective review of craniofacial DCs treated at our institution between 1992 and 2024. Results A total of 117 patients (57 females) were included. The median age at cyst detection and removal were 4.8 months (IQR 3.6-9.6) and 1.8 years (IQR 0.9-5.3), respectively. In 42 patients, parents have noticed the presence of the cyst immediately after birth. Cyst wall rupture during surgical removal was reported in 15.4%. The median follow-up time was 1.3 months (IQR 0.5-12.2). Three patients experienced recurrence. No postoperative complication was reported. The regions with the highest prevalence of ICE were the forehead, frontotemporal scalp, and nasal region. The lateral frontal/temporal scalp had a 33.3% rate of ICE. Midline forehead/scalp lesions demonstrated a higher risk of ICE compared to their lateral equivalents (54.5% vs 17.5%, P = .03). The sensitivity and specificity of magnetic resonance imaging (MRI) were 100% and 95.7%, while for computed tomography (CT scans) were 72.7% and 96.5%. The Area Under the Curve for MRI was 0.978, and for CT was 0.846. The sensitivity and specificity of ultrasound were 50% and 100%. Conclusions Midline forehead/scalp DCs are more prone to extend intracranially than lateral DCs. MRI had a higher sensitivity and specificity than CT scans in detecting ICE. Routine screening imaging should be considered in midline forehead/scalp, lateral frontal/temporal, and nasal DCs.

Objective Our goal is to address the health literacy gap concerning cleft lip and palate using artificial intelligence (AI), specifically OpenAI's ChatGPT-4, to enhance the readability of patient educational materials (PEMs). Additionally, we aim to explore the integration of interactive educational materials into these resources. Design A cross-sectional study. Setting Websites of craniofacial teams approved by the American Cleft Palate-Craniofacial Association (ACPA). Patients/Participants PEMs collected from these websites. Interventions First, we examined the PEMs for interactive educational content such as videos, photos, case examples, and audio clips. Subsequently, we used the WebFX online readability calculator and Grammarly to evaluate the texts’ readability and clarity. After that, we used ChatGPT-4 to simplify the PEM texts to a 6th-grade reading level and re-evaluated their readability and clarity. Main Outcome Measure(s) Readability levels (grade level) and clarity scores of PEMs before and after AI modification, and the presence of interactive educational content. Results Initial evaluations using the Flesch-Kincaid Grade Level formula showed that the texts were written at a median 9th-grade reading level. Modifications using ChatGPT-4 significantly improved readability, achieving a median 6th-grade level and enhanced clarity. Only 27% of the websites featured interactive educational content, indicating a gap in utilizing educational enhancements. Conclusion The use of AI improved the readability and clarity of patient educational materials, aligning with recommended standards. However, the underutilization of interactive tools suggests a need for broader integration of these resources to optimize patient education and engagement.

Objective Recalcitrant palatal fistulas in patients with cleft palate history sometimes require free flap reconstruction. This study reviews the literature on described flaps and outcomes. Design A systematic review was conducted per the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Setting All study designs were included. Non-English articles were excluded. Patients and Participants Patients with a history of cleft palate who underwent free flap reconstruction for a oronasal fistula. Interventions Free tissue transfer for a palatal fistula repair. Main outcomee measures Information regarding defect and flap characteristics were reviewed. Surgical outcomes such as flap loss rates, rates of recurrent fistula formation, and speech outcomes were also obtained. Results Our search returned 894 articles, of which 23 were included. All studies were retrospective case series and reports. A total of 65 patients were described with an average age of 19.3 (range 3–55) years and a median fistula size of 8.00 cm 2 (range 2.54 cm 2 – 24 cm 2 ). The most common flap was the radial forearm flap (n = 37). Nine patients (13.8%) had recurrent fistula formation with surgical revision successful in all cases in which the patient returned to the operating room. There were two partial flap losses and no total flap losses. Speech outcomes showed improvement in 27 patients across 10 studies. Conclusions Palatal fistula repair with free tissue transfer is safe with an acceptable risk profile and low flap loss rate. Early recurrence due to partial flap necrosis and dehiscence are successfully managed with flap readvancement.
