Patients with unilateral cleft lip and palate (UCLP) often exhibit asymmetric paranasal flatness of soft tissues. Despite clinical recognition of this asymmetry, skeletal paranasal asymmetry remains poorly quantified. Measuring skeletal landmark asymmetries can aid in planning surgical maxillary yaw corrections that simultaneously enhance paranasal symmetry and maxillary dental midline position. This study aims to quantify skeletal paranasal asymmetry in patients with UCLP. Skeletally mature patients with complete UCLP who were orthodontically prepared for orthognathic surgery between 2014 and 2023 were included in this study. Presurgical CBCTs were analyzed using Dolphin 3D. Anterior-posterior discrepancies between affected and unaffected sides were measured at the most lateral point of piriform aperture (PA) and 15 mm lateral to PA (15PA). A one-sample t test was conducted. Analysis of 30 patients (mean age 18-8 y, 17 male, 13 female, 20 left-sided, 10 right-sided) was completed. On the affected side, PA and 15PA were positioned 3.8 mm (P<0.05) and 2.4 mm (P<0.05) more posteriorly, respectively. These results suggest that skeletal paranasal asymmetry should be assessed during the pretreatment stage, as presurgical orthodontics should maintain a maxillary midline deviation toward the affected side when yaw correction is indicated. This approach facilitates simultaneous correction of piriform projection and midline alignment during surgery and may reduce the need for secondary procedures, such as malar implants or fat injections, which add cost and morbidity. This study confirms skeletal paranasal asymmetry in patients with UCLP and establishes a standardized method for measuring these deficiencies using CBCT-based skeletal landmarks.

Tessier facial clefts are rare congenital abnormalities and among the most challenging deformities treated by craniofacial surgeons. Despite various surgical interventions, treatment outcomes remain limited, resulting in a higher burden of care and lower quality of life. PreSurgical Infant Orthopedics (PSIO) has shown benefits in cleft care, but its application to Tessier clefts is underreported. This report assesses the long-term surgical outcomes of 3 patients with Tessier clefts who underwent PSIO. The cleft width and premaxilla reduction were observed in all 3 patients.

ObjectiveTo evaluate learners' acceptance of multiuser virtual reality (VR) simulation platform while practicing the Furlow repair technique for cleft palate reconstruction.DesignNonrandomized with pre- and postsurveys.SettingTertiary care institution's Department of Surgery September 2023 through August 2024.ParticipantsTwenty plastic surgery residents from level PGY1 to PGY6 from a single institution.InterventionsMultiuser Meta Quest 2 VR simulation-based workshop with an expert surgeon demonstrating a Furlow cleft palate repair. Feedback included audio and visual.Main outcome measuresLearner confidence in using VR as a tool for surgical education, understanding of the Furlow technique, and opinion regarding the incorporation of VR into surgical and medical education. Satisfaction as measured by the Student Evaluation of Educational Quality questionnaire survey with a 5-point Likert scale (1 = strongly disagree to 5 = strongly agree).Results20 residents participated in this study, of which 65% had previously participated in a cleft palate repair and 40% had used VR. After the simulation, trainees' confidence in using VR as a tool for surgical education, understanding of the Furlow technique, and opinion regarding the incorporation of VR into surgical and medical education significantly increased (P < .05). Trainees found the simulation stimulating (4.85 ± 0.67), interesting (4.45 ± 0.83), clear (4.60 ± 0.82), an effective teaching tool (4.75 ± 0.44) and would recommend it to others (4.90 ± 0.31). Participants reported that they would feel somewhat comfortable repeating the simulation alone (3.95 ± 1.05).ConclusionMultiuser VR-based simulation workshops can significantly increase learners' confidence and skills in the Furlow technique and promote positive opinions regarding VR as an educational tool. Learners considered this platform effective and stimulating and would recommend it as an educational tool.

Virtual surgical planning (VSP) has revolutionized orthognathic and craniomaxillofacial surgeries by enabling precise 3-dimensional analysis, detailed osteotomy planning, and custom fabrication of surgical guides and fixation hardware. However, the visualization of registration holes-critical for accurate plate fixation-remains challenging, especially in a blood-filled surgical field. This paper presents a novel technique to enhance the visibility of registration holes using Bonney's blue dye. The technique involves injecting micro-aliquots of Bonney's blue dye (a mixture of crystal violet and brilliant green) into the registration holes before performing osteotomies. This approach ensures that the holes remain clearly marked despite potential visual contamination in the surgical field. The dye helps to identify screw placements and align patient-specific fixation plates more accurately. The proposed method addresses common difficulties in aligning registration holes with patient-specific plates during surgery. Bonney's blue dye provides a clear contrast against the bone, making the registration holes more visible and easier to locate. This improvement is particularly advantageous in a bloody surgical field and benefits less experienced surgeons by offering a straightforward solution to enhance accuracy and efficiency. The technique can also reduce overall operative time by minimizing the time spent locating and aligning the registration holes. Utilizing Bonney's blue dye in virtual surgical planning significantly improves the visibility and alignment of registration holes in orthognathic surgeries. This simple, cost-effective method enhances surgical precision and efficiency and can be applied to other computer-assisted surgical procedures in craniofacial surgery.

OBJECTIVES/OBJECTIVE:To examine the feasibility of outpatient alveolar bone grafting (ABG) using Exparel (bupivacaine liposome injectable suspension) for donor site analgesia. DESIGN/METHODS:Retrospective, observational study. SETTING/METHODS:Single institution, 39-month retrospective review. PATIENTS/PARTICIPANTS/METHODS:In total, 21 patients with cleft alveolus were included in this study. INTERVENTION/METHODS:In autologous outpatient ABG procedures using a mixed open harvest and Acumed trephine method to retrieve corticocancellous bone from the iliac crest, Exparel was injected in the donor site fascia. MAIN OUTCOME MEASUREMENTS/METHODS:Postoperative data including length of stay, post anesthesia care unit narcotics delivered, and maximum pain scores were recorded. Successful outcomes were assessed by exploring 30-day complications, 30-day emergency department visits, 30-day readmissions, and ambulation at follow-up. RESULTS:The average hospital length of stay was 360.8 min. Four patients required overnight stay secondary to pain. The average doses of pain medications administered postoperatively were 198.4 mg acetaminophen, 9.3 mg ketorolac, 3.0 µg fentanyl, and 1.5 mg oxycodone. No patient reported 30-day complications secondary to donor site pain, 30-day emergency department visits, or 30-day readmissions, and there was only one case of wound dehiscence. All patients exhibited proper ambulation at follow-up and healed well from ABG. CONCLUSIONS:The use of Exparel for donor site analgesia in outpatient ABG procedures using corticocancellous grafts can result in adequate pain management and ambulation without an increased risk of complications and readmissions.

MAIN OBJECTIVE/OBJECTIVE:To analyze postoperative palatoplasty outcomes before and after systemic protocol changes to preferred bottle and arm immobilizer use after surgery. DESIGN/METHODS:Retrospective, cohort study. SETTING/METHODS:Urban, academic, tertiary medical center in New York City, NY. PARTICIPANTS/METHODS:= 39). INTERVENTIONS/METHODS:Protocols were amended over the 2018 calendar year to allow for utilization of the baby's preferred bottle (vs alternative feeding methods) and hand socks (vs arm immobilizers) in the immediate postoperative period. Data was extrapolated from electronic medical records to compare surgical outcomes. MAIN OUTCOME MEASURES/METHODS:Postoperative wound complications (fistula and dehiscence) that did not resolve within 1 month, length of stay (hours), and 30-day re-admission. Nonparametric Mann-Whitney U tests and Fisher's Exact test were utilized for statistical analysis. RESULTS: = .366). CONCLUSIONS:The findings from this study suggest relaxing postoperative protocols following palatoplasty to allow immediate bottle feedings and unrestricted arm use may be safe without compromise to surgical outcomes.

STUDY DESIGN/UNASSIGNED:Retrospective observational study. OBJECTIVE/UNASSIGNED:This study analyzes the epidemiology of pediatric Le Fort fractures and assesses the incidence of concomitant injuries and acute-level hospital course using the largest, national pediatric trauma database to date. METHODS/UNASSIGNED:Pediatric midface and Le Fort fractures from 2016-2019 were identified in the National Trauma Data Bank. Descriptive analyses of Le Fort compared to non-Le Fort midface fractures were performed. Multivariable regression assessed whether Le Fort fractures were risk factors for ICU admission, intracranial injury, cervical spine (C-spine) fracture, tracheostomy, and mortality. RESULTS/UNASSIGNED:< 0.001). Incidence of all the above increased with higher-grade Le Fort fractures. Le Fort III fractures had higher rates of mortality than non-Le Fort midface fractures (7.6% vs 3.2%). Multivariable regression showed that all Le Fort patterns were independent risk factors for tracheostomy and ICU admission, but only Le Fort I for C-spine fractures. CONCLUSIONS/UNASSIGNED:The incidence of Le Fort fractures appears to increase with age. Higher category Le Fort fractures are associated with greater morbidity.

OBJECTIVES/OBJECTIVE:To assess surgical instrument usage in cleft lip (CL) and cleft palate (CP) surgery and create an optimized surgical tray with an associated cost-savings analysis. DESIGN/METHODS:Prospective, observational study. SETTING/METHODS:Single institution, 6-month prospective review. PATIENTS/PARTICIPANTS/METHODS:A total of 10 primary CL surgeries and 10 primary CP surgeries were included in this study. INTERVENTION/METHODS:Complete lists of surgical instruments utilized in CL and CP surgeries were collected. UNLABELLED:Utilization fractions (UFs) were calculated as the percentages of average used instruments to averaged opened instruments per case. New optimized CL and CP surgical trays were idealized by removing instruments not used in at least 20% of cases, and a cost analysis was performed to identify potential savings. Calculation of annual potential savings was also conducted based on institutional caseload. RESULTS:The average instrument UFs were 26.0% for CL and 22.6% for CP. The estimated costs were $33.15 to $290.29 for the original CL surgical tray and $10.20 to $63.80 for the optimized tray. For CP, the original tray's cost was estimated at $38.25 to $319.00, and the optimized tray at $9.18 to $57.42. This demonstrates a cost reduction of $22.95 to $226.49 for CL and $29.07 to 261.58 for CP. CONCLUSIONS:The idealized surgical instrument tray could contribute to reducing healthcare expenditures and promoting operating room efficiency, patient safety, and environmentally friendlier operating theaters.

Nasoalveolar molding (NAM) is an early presurgical intervention to facilitate primary cleft lip repair by reducing cleft severity and improving labial and nasal form. However, it continues to be associated with the burden of care that influences access and completion of therapy. The authors, therefore, aim to determine the burden of care of NAM therapy for families seeking treatment at a high-volume urban cleft center. A retrospective study of all patients undergoing primary cleft repair between 2012 and 2020 was performed. Patients were grouped based on whether or not NAM therapy was offered. Variables including physical, psychosocial, and financial factors were assessed. Two hundred and thirty patients underwent primary cleft repair between 2012 and 2020. Of these, 176 patients were indicated for NAM, with 4% discontinuing, and 54 patients did not undergo NAM. The 169 patients who completed NAM had a mean duration of treatment of 13.6±8.8 wks consisting of 15±6 scheduled NAM adjustment visits and 1±1 unscheduled visit made urgently to assess caregiver concerns. The mean travel distance was 28.6±37.1 miles. Eighty-four percent of caregivers were married, and 16% did not have English as a primary language. Though 57% had private insurance, 43% of patients received charity support for their treatment. NAM is a finite presurgical intervention that requires caregivers to participate in patient care for approximately three months of their early life. The decision to pursue NAM should be considered alongside the burden of care for caregivers to complete treatment.

INTRODUCTION/BACKGROUND:The Abbe flap is a standard intervention to treat upper lip deformities in patients with bilateral cleft lip. This two-stage procedure requires a 2 to 3-week period in which the superior and inferior lips remain connected. This study evaluates the safety of Abbe flap division and inset prior to 14 days' time. MATERIALS AND METHODS/METHODS:A single institution, 8-year review of all patients with a bilateral cleft lip who underwent Abbe flap reconstruction was performed. Patients were classified into two groups: those whom division was performed 14 days or later and those with division earlier than 14 days. RESULTS:A total of 26 patients were identified. Patients who underwent Abbe flap division in less than 14 days (n = 10) demonstrated an average time to division of 9.7 days (range 7-13 days) with no evidence of flap loss, wound breakdown or infection. Patients who underwent Abbe flap division within 14 days or more (n = 16) demonstrated an average time to division of 15 days with four minor complications and no flap loss. CONCLUSION/CONCLUSIONS:Dividing the Abbe flap after the first postoperative week appears to be safe and without additional risk to flap loss or wound breakdown. A shorter time to Abbe flap division may decrease the burden of care on patients and their caregivers.
