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: Venous thromboembolism (VTE) poses a major risk after abdominal contouring surgery, impacting morbidity and mortality. Despite various preventative strategies, surgeons are cautious about using enoxaparin for extended postoperative periods. This study aims to determine if a 7-day postoperative course of enoxaparin increases bleeding risks compared with a single dose of intraoperative unfractionated heparin in patients undergoing abdominal contouring surgery. Methods: A retrospective cohort analysis was performed on patients who underwent abdominoplasty or panniculectomy from August 2017 to October 2023. Patients were split into 2 groups: Group 1 received 5000 units of intraoperative unfractionated heparin in addition to 7 days of postoperative enoxaparin (40 mg daily); group 2 received only the intraoperative heparin dose. Primary outcomes included bleeding events and VTE incidence. Secondary outcomes were seroma, infection, surgical site dehiscence, necrosis, drain duration, and reoperation rates. Results: The study included 121 patients (111 women, 10 men), with 61 patients in group 1 and 60 in group 2. The average age was 49 ± 12 years, and the average body mass index was 29.8 ± 5 kg/m². No cases of VTE were reported. Postoperative bleeding occurred in 3 patients (4.9%) in group I and 2 patients (3.3%) in group 2, showing no statistically significant difference (P = 0.66). Secondary outcomes also showed no significant differences between the groups. Conclusions: Our study of 121 patients undergoing either abdominoplasty or panniculectomy demonstrated that administering enoxaparin for 7 days postoperatively is safe and does not increase the risk of bleeding.

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.

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.

Background: With neck, aging the cervicomental angle becomes obtuse and may be influenced by hyoid bone aging. An understanding of hyoid position changes with aging will further our understanding of its role in neck contour changes. Methods: A 3D volumetric reconstruction of 282 neck computed tomography scans was performed. The cohort was categorized into three groups based on age: 20 years or older and younger than 40 years, 40 years or older and younger than 60 years, and 60 years or older and younger than 80 years. The vertical and horizontal hyoid distances in relation to the mandible were calculated for each patient. Results: A total of 282 patients (153 women, 129 men) were included in the cohort. The age groups were evenly distributed in men and women. Mean hyoid vertical and horizontal distances differed between women and men in all age groups. There was a significant difference in the hyoid vertical distance between 20–39 years old to 40–59 years old in men (P < 0.01), and 20–39 years old to 60–79 years old in both genders (women P = 0.005, men P < 0.01). Hyoid horizontal distance was not affected by age and sex (age and sex: P > 0.05), but rather by body mass index (BMI). Every 5 BMI points corresponded to a forward movement of 2 mm. Conclusions: As individuals age, the hyoid bone descends in both sexes, and an increase in BMI is associated with forward movement. Additional studies are needed to assess the correlation of the hyoid position between upright and supine positions.
