Sphenoorbital meningiomas are a challenge to access and reconstruct. Although there is much neurosurgical literature on resection of such tumors, there is little discussion on the best methods for the reconstruction of consequent defects, which are often extensive due to large areas of hyperostosis requiring resection. We performed a retrospective analysis of patients who underwent resection and reconstruction of a sphenoorbital meningioma by the senior authors (C.S. and D.A.S.) between 2010 and 2020. Surgical access in all cases included an orbitozygomatic osteotomy. The study cohort consisted of 23 patients (20 female, 3 male) with an average age of 50 (range: 37-72) years at the time of surgery. Most patients had progressive proptosis before the ablative operation. Orbital reconstruction was with a combined titanium-Medpor implant in 18 patients, split calvarial bone graft in 3 patients, and a Medpor implant in 2 patients. Calvarial reconstruction was performed with titanium mesh in 21 patients, split calvarial bone graft and titanium mesh in 1 patient, and craniotomy bone and titanium plate in 1 patient. Reoperation was required in 7 patients due to hypoglobus or enophthalmos (N=2), orbital implant malposition (N=1), abscess (N=1), pain (N=1), intracranial fat graft modification (N=1), and soft tissue deformities (N=2). Our experience demonstrates that sphenoorbital meningiomas can require broad areas of resection of the skull base and calvarium and necessitate comprehensive reconstruction of the anterior cranial fossa, orbital walls, and cranium. Collaboration between craniofacial surgeons and neurosurgeons can achieve optimal results.

BACKGROUND:Many cleft centers incorporate NasoAlveolar Molding (NAM) into their presurgical treatment protocols. However, there are limited data on eligible patients who do not receive or complete NAM. This study characterizes the demographics associated with non-utilization or completion of NAM. METHODS:A single-institution retrospective review was performed of all patients with cleft lip and alveolus undergoing primary unilateral and bilateral cleft lip repair from 2012-2020. Patients were grouped based on utilization or non-utilization of NAM. Demographic and treatment data were collected, including documented reasons for not pursuing or completing NAM. RESULTS: < .001). CONCLUSIONS:Common reasons for non-utilization of NAM include well-aligned cleft alveolus, medical complexity, and late presentation. Early presentation is an important modifiable factor affecting rates of NAM utilization.

OBJECTIVE:The aim of this study was to evaluate the outcomes of orthognathic surgery (OGS) in patients with craniofacial microsomia (CFM) who had previously undergone mandibular distraction osteogenesis (MDO). DESIGN/METHODS:A retrospective cohort study was performed including all patients with CFM who were treated with OGS at a single institution between 1996 and 2019. The clinical records, operative reports, and cone beam computed tomography (CBCT) scans were reviewed. CBCT data before OGS (T1), immediately after OGS (T2), and at long-term follow-up (T3) were analyzed using Dolphin three-dimensional software to measure the occlusal cant and chin point deviation. RESULTS:  =  .808). CONCLUSIONS:Within the limitations of this study, these findings suggest that OGS after MDO in patients with CFM can produce stable results.

Objective: Compare short term surgical outcomes and trends in cleft lip repair with or without gingivoperiosteoplasty (GPP). Design: Retrospective review of the ACS NSQIP-Pediatric database from 2014 to 2019. Patients: Patients between 2 and 18 months of age undergoing any initial cleft lip repair, with or without GPP, were selected via relevant CPT^® codes. Main Outcome Measures: Patient demographics, comorbidities, 30-day readmissions and post-operative complications are assessed. Results: From 2014 to 2019, a total of 6269 patients were identified, of which 6.67% underwent GPP (n = 418). Patients undergoing GPP were significantly older with an average age of 9 months compared to 5 months in the non-GPP group (P <.001). Co-morbidities were similar amongst both cohorts, although patients undergoing GPP were more likely to have a higher ASA class (P =.006), cardiac risk factors (P =.012) and syndromic diagnosis (P <.001). There were no differences in 30-day short term surgical outcomes. GPP was associated with increased operative time by ~25 minutes when compared to cleft lip repair alone (P <.001). Conclusion: GPP was not associated with increased 30-day postoperative complications, readmission, reoperation, or total length of hospital stay, and was associated with an increased operative time of 25 minutes. Children undergoing GPP were significantly older in age and were more likely to have a higher ASA class/cardiac risk factors.

BACKGROUND:This study characterizes the potential loss of velar length in patients with a wide cleft and rescue of this loss of domain by local flap reconstruction, providing anatomic evidence in support of primary lengthening of the soft palate during palatoplasty. METHODS:A retrospective review was conducted of all patients with a cleft palate at least 10mm in width, who underwent primary palatoplasty with a buccal flap prior to 18 months of age over a 2-year period. All patients underwent primary palatoplasty with horizontal transection of the nasal mucosa, which was performed after nasal mucosa repair, but prior to muscular reconstruction. The resulting palatal lengthening was measured and the mucosal defect was reconstructed with a buccal flap. RESULTS:Of the 22 patients included, 3 (13.6%) had a history of Pierre Robin sequence, and 5 (22.7%) had an associated syndrome. No patients had a Veau I cleft, 7 (31.8%) had a Veau II, 12 (54.5%) had a Veau III, and 3 had (13.6%) a Veau IV cleft. All patients had a right buccal flap during primary palatoplasty. The mean cleft width at the posterior nasal spine was 10.6  ±  2.82mm, and mean lengthening of the velum after horizontal transection of the nasal mucosa closure was 10.5  ±  2.23mm. There were 2 (9.1%) fistulas, 1 (4.5%) wound dehiscence, 1 (4.5%) 30-day readmission, and no bleeding complications. CONCLUSIONS:Patients with a wide cleft palate have a potential loss of 1cm velar length. The buccal flap can rescue the loss of domain in palatal length, and potentially improve palatal excursion.

BACKGROUND:Vascularized composite allotransplantation (VCA) has redefined the frontiers of plastic and reconstructive surgery. At the cutting edge of this evolving paradigm, we present the first successful combined full face and bilateral hand transplant (FT-BHT). METHODS:A 21-year-old man with sequelae of an 80% total body surface area burn injury sustained following a motor vehicle accident presented for evaluation. The injury included full face and bilateral upper extremity composite tissue defects, resulting in reduced quality of life and loss of independence. Multidisciplinary evaluation confirmed eligibility for combined FT-BHT. The operative approach was validated through 11 cadaveric rehearsals utilizing computerized surgical planning. Institutional review board and organ procurement organization approvals were obtained. The recipient, his caregiver, and the donor family consented to the procedure. RESULTS:Combined full face (eyelids, ears, nose, lips, and skeletal subunits) and bilateral hand transplantation (forearm level) was performed over 23 hours on August 12-13th, 2020. Triple induction and maintenance immunosuppressive therapy and infection prophylaxis were administered. Plasmapheresis was necessary postoperatively. Minor revisions were performed over seven subsequent operations, including five left upper extremity, seven right upper extremity, and seven facial secondary procedures. At eight months, the patient is approaching functional independence and remains free of acute rejection. He has significantly improved range of motion, motor power, and sensation of the face and hand allografts. CONCLUSION/CONCLUSIONS:Combined FT-BHT is feasible. This is the most comprehensive VCA procedure successfully performed to date, marking a new milestone in plastic and reconstructive surgery for patients with otherwise irremediable injuries.

OBJECTIVE:Primary cleft nasal repair can include septal reconstruction. We hypothesize that primary cleft septoplasty and adult septoplasty have fundamental differences that render these procedures as distinct surgical entities. DESIGN/METHODS:Systematic review of the PubMed, Cochrane, and Embase databases performed on pediatric cleft and general adult septoplasty techniques through December 2021. (PROSPERO ID CRD42022295763). MAIN OUTCOME MEASURES/METHODS:Collected data included information on septal dissection, septal detachment, and management of the bony and cartilaginous septum. RESULTS:Twenty-eight pediatric cleft septoplasty and 229 adult septoplasty studies were included. Dissection in primary cleft septoplasty was limited to the anterocaudal septum, while secondary cleft septoplasty and adult septoplasty techniques entailed wide exposures of the cartilaginous septum with or without exposure of the perpendicular plate of the ethmoid. In primary cleft septoplasty, detachment of the septum was mostly limited to the nasal spine and anterior base of the cartilaginous septum, while secondary cleft septoplasty and adult septoplasty included detachment from the vomer, and ethmoid. In the few reports of cartilage excision during primary cleft septoplasty, removal was limited to the anterior inferior border of the septum, while secondary cleft septoplasty and adult septoplasty included excision of the cartilaginous and bony septum. CONCLUSION/CONCLUSIONS:Primary cleft septoplasty is distinct from septoplasty performed on facially mature patients. More specifically, septal dissection and detachment are limited to the anterior caudal area during primary lip repair, with rare removal of cartilage or bone. Given these differences, the authors suggest the term "septal reset" to describe septoplasty performed during primary cleft nasal repair.

The current standard of care for an alveolar cleft defect is an autogenous bone graft, typically from the iliac crest. Given the limitations of alveolar bone graft surgery, such as limited supply, donor site morbidity, graft failure, and need for secondary surgery, there has been growing interest in regenerative medicine strategies to supplement and replace traditional alveolar bone grafts. Though there have been preliminary clinical studies investigating bone tissue engineering methods in human subjects, lack of consistent results as well as limitations in study design make it difficult to determine the efficacy of these interventions. As the field of bone tissue engineering is rapidly advancing, reconstructive surgeons should be aware of the preclinical studies informing these regenerative strategies. We review preclinical studies investigating bone tissue engineering strategies in large animal maxillary or mandibular defects and provide an overview of scaffolds, stem cells, and osteogenic agents applicable to tissue engineering of the alveolar cleft. An electronic search conducted in the PubMed database up to December 2021 resulted in 35 studies for inclusion in our review. Most studies showed increased bone growth with a tissue engineering construct compared to negative control. However, heterogeneity in the length of follow up, method of bone growth analysis, and inconsistent use of positive control groups make comparisons across studies difficult. Future studies should incorporate a pediatric study model specific to alveolar cleft with long-term follow up to fully characterize volumetric defect filling, cellular ingrowth, bone strength, tooth movement, and implant support.

This case presents a facially mature patient with Beckwith-Wiedemann Syndrome (BWS) who presented with severe class III malocclusion. Computed tomography imaging revealed an anterior crossbite of 19 mm and a narrow pharyngeal airway at the level of the tongue base precluding mandibular setback surgery. The patient was indicated for a LeFort III combined with a LeFort I advancement, each of 10 mm, for a 20 mm combined advancement. Stable, functional occlusion was achieved without airway compromise. This novel use of the combined LeFort III/I can restore stable class I occlusion in patients with BWS at risk for tongue base airway compromise.

OBJECTIVE:Describe the first hybrid global simulation-based comprehensive cleft care workshop, evaluate impact on participants, and compare experiences based on in-person versus virtual attendance. DESIGN/METHODS:Cross-sectional survey-based evaluation. SETTING/METHODS:International comprehensive cleft care workshop. PARTICIPANTS/METHODS:Total of 489 participants. INTERVENTIONS/METHODS:Three-day simulation-based hybrid comprehensive cleft care workshop. MAIN OUTCOME MEASURES/METHODS:Participant demographic data, perceived barriers and interventions needed for global comprehensive cleft care delivery, participant workshop satisfaction, and perceived short-term impact on practice stratified by in-person versus virtual attendance. RESULTS: = .01). CONCLUSION/CONCLUSIONS:Hybrid simulation-based educational comprehensive cleft care workshops are overall well received by participants and have a positive perceived impact on their clinical practices. In-person attendance is associated with significantly higher satisfaction and perceived impact on practice. Considering that financial and health constraints may limit live meeting attendance, future efforts will focus on making in-person and virtual attendance more comparable.
