Virtual Surgical Planning in Condyle Reconstruction of Posterior Mandibulectomy Defects.

Background: Ameloblastoma is a rare odontogenic tumor most commonly located within the mandible. These tumors can grow to massive proportions and result in malocclusion. Segmental mandibulectomy and reconstruction with an osteocutaneous free flap are frequently required. Virtual surgical planning (VSP) aids the surgeon in creating precise anatomic reconstruction when there is preoperative malocclusion due to tumor size. In this study we seek to further examine reconstruction of posterior mandibulectomy defects inclusive of condylar resection. Methods: Retrospective review of patients treated for giant ameloblastoma (tumor >4 cm) was examined; 3 patients with posterior tumors requiring ramus and condylar resection were included. Reconstruction in all patients was performed using fibula free flaps and VSP custom-made mandibular reconstruction plates. In these patients the reconstructed ramus was shortened and precise contouring done with a burr to recreate the native condylar surface. Intermaxillary fixation was used to maintain occlusion for 1 month postoperatively. Inferior alveolar nerve repair with allograft and nerve connectors was performed for all 3 patients. Results: All patients underwent successful mandibular reconstruction with preservation of mandibular function and improved occlusion postoperatively. Inferior alveolar nerve repair using nerve allograft allowed for neurosensory recovery in the mandibular division of trigeminal nerve distribution in 2 of the 3 patients. Conclusions: Giant ameloblastoma involving the mandibular condyle can be successfully treated with the fibula free flap utilizing mandible reconstruction plates and VSP. This technique allows for excellent restoration of occlusion and neurosensory recovery when paired with reconstruction of the inferior alveolar nerve at time of reconstruction.

"Travel Burden to ACPA Approved Cleft and Craniofacial Teams: A Geospatial Analysis".

BACKGROUND: Despite the existence of American Cleft Palate and Craniofacial Association (ACPA)-approved Cleft and Craniofacial Teams, access to multidisciplinary team-based care remains challenging for patients from rural areas, leading to disparities in care. We investigated the geospatial relationship between U.S. counties and ACPA-approved centers. METHODS: The geographic location of all ACPA-approved cleft and craniofacial centers in the U.S. was identified. Distance between individual U.S. counties (n=3,142) and their closest ACPA-approved team was determined. Counties were mapped based on distance to nearest cleft or craniofacial team. Distance calculations were combined with U.S Census data to model the number of children served by each team and economic characteristics of families served. These relationships were analyzed using independent t-tests and ANOVA. RESULTS: Over 40% of U.S. counties did not have access to an ACPA-approved craniofacial team within a 100-mile radius (n=1,267) versus 29% for cleft teams (n=909). Over 90% of counties greater than 100 miles to a craniofacial team had a population <7,500 (n=1,150). Of the counties >100 miles from a cleft team, 64% had a child poverty rate greater than national average (n=579). Counties with the highest birth rate and >100 miles to travel to an ACPA team are in the Mountain West. CONCLUSIONS: Given the time-sensitive nature of operative intervention and access to multidisciplinary care, the lack of equitable distribution in certified cleft and craniofacial teams is concerning. Centers may better serve families from distant areas by establishing satellite clinics, telehealth visits, and training local primary care providers in referral practices.

Oncoplastic Breast Reduction: A Systematic Review of Postoperative Complications.

Background: Breast-conserving therapy with oncoplastic reduction is a useful strategy for partial mastectomy defect reconstruction. The most recently published systematic review of oncoplastic breast reduction outcomes from 2015 showed wound dehiscence in 4.3%, hematoma in 0.9%, infection in 2.8%, and nipple necrosis in 0.9% of patients. We performed a systematic review of oncoplastic breast reduction literature, comparing outcomes and complication rates reported over the past 8 years. Methods: Studies describing the use of oncoplastic breast reduction and discussion of postoperative complications were included. The primary outcome assessed was the postoperative complication rate; secondary outcomes analyzed were rates of margin expansion, completion mastectomy, and delays in adjuvant therapy due to complications. Results: Nine articles met inclusion criteria, resulting in 1715 oncoplastic breast reduction patients. The mean rate of hematoma was 3%, nipple necrosis was 2%, dehiscence was 4%, infection was 3%, and seroma was 2%. The need for re-excision of margins occurred in 8% of patients, and completion mastectomy in 2%. Finally, delay in adjuvant treatment due to a postoperative complication occurred in 4% of patients. Conclusions: Oncoplastic breast reduction is an excellent option for many patients undergoing breast-conserving therapy; however, postoperative complications can delay adjuvant radiation therapy. Results of this systematic literature review over the past 8 years showed a slight increase in complication rate compared to the most recent systematic review from 2015. With increased popularity and surgeon familiarity, oncoplastic breast reduction remains a viable option for reconstruction of partial mastectomy defects despite a slight increase in complication rate.

Comparison of inferior gluteal artery perforator flaps versus vertical rectus abdominis musculocutaneous flaps in the reconstruction of perineal wounds.

BACKGROUND: Achieving a healed perineal wound following chemoradiotherapy and abdominoperineal resection (APR) is challenging for surgeons and patients. Prior studies have shown trunk-based flaps, including vertical rectus abdominis myocutaneous (VRAM) flaps, are superior to both primary closure and thigh-based flaps; however, there has been no direct comparison with gluteal fasciocutaneous flaps. This study evaluates postoperative complications after various methods of perineal flap closure of APR and pelvic exenteration defects. METHODS: Retrospective review of patients who underwent APR or pelvic exenteration from April 2008 through September 2020 was analyzed for postoperative complications. Flap closure techniques, including VRAM, unilateral (IGAP), and bilateral (BIGAP) inferior gluteal artery perforator fasciocutaneous flaps, were compared. RESULTS: Of 116 patients included, the majority underwent fasciocutaneous (BIGAP/IGAP) flap reconstruction (n = 69, 59.6%), followed by VRAM (n = 47, 40.5%). There were no significant differences between group patient demographics, comorbidities, body mass index, or cancer stage. There were no significant differences between BIGAP/IGAP and VRAM groups in minor complications (57% versus 49%, p = 0.426) or major complications (45% versus 36%, p = 0.351), including major/minor perineal wounds. CONCLUSIONS: Prior studies have shown flap closure is preferable to primary closure after APR and neoadjuvant radiation but lack consensus on which flap offers superior postoperative morbidity. This study comparing outcomes of perineal flap closure showed no significant difference in postoperative complications. Fasciocutaneous flaps are a viable choice for the reconstruction of these challenging defects.

Gaining the Upper Hand: Understanding the Causes and Repercussions of Delayed Presentation of Congenital Hand Anomalies.

Congenital upper extremity anomalies are common, with an incidence of 27.2 per 10,000 births.1 This case series highlights patients with delayed presentation of congenital hand anomalies due to breakdowns in referral to pediatric hand surgery. A retrospective review of patients with congenital hand anomalies with delayed presentation to the University of Mississippi Medical Center Congenital Hand Center was performed, and 3 patients were included. Delays in care result from a variety of missteps for patients and parents navigating the health system. In our case series, we observed fear of surgical correction, lack of expected impact to quality of life, and paucity of knowledge of available surgical options by the patient's pediatrician. While all patients underwent successful reconstruction of their congenital hand anomalies, these delays in care resulted in more demanding surgeries and prolonged return to normal hand use. Early referral to pediatric hand surgery for congenital hand anomalies is critical to avoid delays in care and unfavorable post-operative outcomes. Educating primary care physicians of regional surgeon availability, surgical options, ideal reconstruction timelines, and methods to encourage parents to pursue surgical options early for correctable deformities can improve patient outcomes and lessen resultant social consequences in patients with congenital hand anomalies.

Bipedicled Palatoplasty for Closure of Wide Veau Class II Anterior Palatal Defect: A Case Series.

Background: Wide palatal defects remain a challenge to the plastic surgeon. The authors present a new method for closure of a wide Veau class II cleft palate in which anterior palatal closure was achieved by use of a bipedicled mucoperiosteal anterior palatal flap. Methods: Two patients with wide Veau class II cleft palatal defects underwent palatoplasty with difficulty in closing the anterior palate. A novel technique was employed for tension-free closure. Results: A tension-free closure in the midline was achieved with a bipedicled mucoperiosteal anterior palatal flap. Conclusions: This novel technique can assist with closure of the anterior-most portion of hard palatal defects.

Tissue Expander for Pediatric Scalp Reconstruction Complicated by Fungal Infection With Aspergillus terreus.

Background: Tissue expansion is an effective option for soft tissue reconstruction of the scalp in the pediatric population. Unfortunately, this approach carries a high risk of such complications as infection and expander exposure. While bacterial infection of alloplastic materials is most frequent, when fungal infections occur, the outcomes can be devastating. Purpose: To inform the management of fungal tissue expander infections, this report describes a case of expander-based scalp reconstruction complicated by Aspergillus terreus infection in a pediatric patient. Methods: A patient who had blunt-force head trauma presented with soft tissue injury and depressed skull fracture requiring emergent craniectomy. After stabilization, a paucity of soft tissue coverage required further surgical intervention before reconstructive cranioplasty. Six months after her injury, two remote port subgaleal tissue expanders were placed. Subsequently, purulent drainage developed from the surgical incision. Results: Infection resulted in expander exposure requiring device removal and treatment with clindamycin and ceftazidime while awaiting culture results. Intraoperative cultures were positive for Aspergillus terreus and methicillin-sensitive Staphylococcus aureus, for which she received systemic voriconazole for 23 days and cephalexin for 10 days. Conclusions: Though tissue expansion remains a viable reconstructive option, fungal infection can be disastrous, requiring systemic antifungal therapy, surgical debridement, and expander removal.

Use of Rectus Femoris Muscle Flap in Patients With Absent Profunda Femoris Vascular Flow.

Background: The rectus femoris (RF) muscle flap is an excellent choice for soft tissue coverage of complex wounds of the groin because of its reliable vascular anatomy and sufficient bulk allowing coverage of vascular anastomoses. The muscle receives its blood supply from the descending branch of the lateral femoral circumflex artery (dLFCA), which originates from the profunda femoris artery (PFA) in the proximal thigh. This case series reports 3 patients on whom pedicled RF muscle flaps were performed successfully despite known occlusion of the PFA preoperatively. Methods: All 3 patients had a history of peripheral vascular disease (PVD) and underwent femoral-popliteal bypass. This was complicated by pseudoaneurysm in 2 patients and exposure of the polytetrafluorethylene graft in the third patient. Computed tomography angiography (CTA) or traditional angiography was obtained for each patient, showing occlusion of the PFA. After adequate debridement and confirming flow through the pedicle, vascular graft coverage at the groin was performed using a pedicled RF muscle flap, followed by split thickness skin grafting (n = 2) or primary skin closure (n = 1). Results: The 3 patients included in this report had successful coverage of exposed vascular bypass grafts in the groin utilizing pedicled RF muscle flaps despite known occlusion of the PFA preoperatively. Follow-up at 3 months postoperatively showed healthy flaps with well-healed overlying skin graft or closure for all patients. Conclusions: The pedicled RF muscle flap may be successfully used for coverage of complex groin wounds in patients with occlusion of the PFA. This flap is useful in complex groin wounds related to vascular interventions, particularly when other local options have been exhausted. This case report presents 3 successful cases of groin wound coverage using pedicled RF muscle flap despite known preoperative occlusion of the PFA.

Knee Reconstruction following Sarcoma Resection Utilizing Pedicled Anterolateral Thigh Propeller Flap: A Case Series.

Coverage of knee wounds with exposure or violation of the joint capsule has long been a challenge to plastic surgeons. Wide resection and radiation treatment for soft-tissue sarcomas further this difficulty due to resultant diminished vascularity and soft tissue fibrosis. Traditional muscle flaps such as the gastrocnemius may be within the radiated field, limiting their arc of rotation to the knee. We present a series of exposed knee joint reconstructions using pedicled propeller flaps after sarcoma resection. Three patients diagnosed with soft tissue sarcomas underwent neoadjuvant radiation followed by wide local resection by orthopedic oncology. All patients had underlying knee joint exposure and underwent successful soft tissue reconstruction utilizing pedicled anterolateral thigh (ALT) propeller flaps. The ALT flap is widely used in plastic surgery for reconstruction of soft tissue defects due to its reliable vascularity, long pedicle, versatility, low donor-site morbidity, and large size. As a propeller flap, we demonstrate this is a viable alternative for reconstruction when the vascular plexus around the knee is unreliable after neoadjuvant radiation. Extending the ALT propeller flap with a large proximal skin paddle provides a nonmicrosurgical alternative to traditional muscle flaps at this location. The ALT propeller flap is an excellent option for reconstruction of large defects of the knee, especially in the setting of a radiated wound bed with unpredictable vascularity. In our case series, all three patients underwent successful reconstruction of exposed knee joints after resection of soft tissue sarcoma utilizing ALT propeller flaps.

Intraoperative Frozen Section Analysis for the Excision of Nonmelanoma Skin Cancer: A Single-Center Experience.

Surgical resection of nonmelanoma skin cancer (NMSC) may be performed via Mohs micrographic surgery (MMS) or standard surgical excision with complete margin analysis. Whereas MMS may necessitate delayed reconstruction surgery, intraoperative frozen section analysis (IFSA) may be used to ensure clear surgical margins before proceeding with reconstruction. To achieve curative resection while optimizing aesthetic outcomes, surgeons may use surgical excision guided by IFSA to forego extensive or delayed reconstruction. Patients undergoing wide local excision for NMSC using IFSA from October 2008 to November 2016 were evaluated. Analysis included IFSA versus permanent section outcomes, the number of required excisions, and the recurrence rate. Our analysis contained 145 patients involving 162 lesions. IFSA demonstrated that 73.4 per cent of margins were negative after one excision and 26.5 per cent were re-excised until achieving negative margins. Analysis revealed one false-positive case (0.62%) and four false-negative cases (2.47%). Nine patients had local recurrence (5.56%). Frozen section sensitivity was 88.99 per cent and specificity 99.20 per cent. The positive predictive value was 96.97 per cent, and negative predictive value was 96.90 per cent. Mean follow-up time was 39 months. Both resection and recurrence data of excised NMSC lesions at our institution suggest that surgical excision using IFSA is a safe and effective alternative to MMS.
