Generation of Cross-Specialty Consensus Statements on Soft Tissue Management via a Modified Delphi Method.

BACKGROUND: Soft tissue management (STM) training programs for surgeons are largely tradition based, and substantial differences exist among different surgical specialties. The lack of comprehensive and systematic clinical evidence on how surgical techniques and implants affect soft tissue healing makes it difficult to develop evidence-based curricula. As a curriculum development group (CDG), we set out to find common grounds in the form of a set of consensus statements to serve as the basis for surgical soft tissue education. METHODS: Following a backward planning process and Kern's six-step approach, the group selected 13 topics to build a cross-specialty STM curriculum. A set of statements based on the curriculum topics were generated by the CDG through discussions and a literature review of three topics. A modified Delphi process including one round of pilot voting through a face-to-face CDG meeting and two rounds of web-based survey involving 22 panelists were utilized for the generation of consensus statements. RESULTS: Seventy-one statements were evaluated, and 56 statements reached the 80% consensus for "can be taught as is." CONCLUSIONS: Using a modified Delphi method, a set of cross-specialty consensus statements on soft tissue management were generated. These consensus statements can be used as a foundation for multi-specialty surgical education. Similar methods that combine expert experience and clinical evidence can be used to develop specialty-specific consensus on soft tissue handling.

Transnasal tension suture of external nasal splints: A reliable, novel technique.

BACKGROUND: We routinely apply external nasal splints after closed nasal reduction or rhinoplasty and secure the splint by transnasal suturing. We seek to describe our technique and review our experience. METHODS: A retrospective chart review was performed to review patients who had an external nasal splint secured by transnasal suturing. The technique consists of steristrips applied across the dorsum and nasal bones. The Aquaplast is molded to the nose and a 2-0 polypropylene suture on a straightened tapered needle or a Keith needle is passed through the splint, the nasal sidewalls and septum, through the splint on the contralateral side, and back again in a horizontal mattress fashion. The suture is tied down to maintain the desired shape of the splint. The splint is removed in the first postoperative followup (10-14 days). RESULTS: Mean patient age was 31.5 years, 82 male and 18 female patients were reviewed, 67 % of splints were placed for closed reduction of acute nasal trauma, and 33 % placed after elective rhinoplasty for late correction of functional and cosmetic traumatic deformity. No splints were inadvertently removed by patients prior to followup. Splints were removed an average of 12 days postoperatively, and mean followup was 27 weeks. There were no complications related to transnasal suturing of the splint, such as skin ulceration, pressure necrosis, identifiable scarring related to the suture entry points or breathing difficulty attributable to internal nasal valve narrowing. CONCLUSION: Transnasal suturing is a safe and reliable method for fixation of an external nasal splint.

The Medial Femoral Condyle Free Flap for Reconstruction of Recalcitrant Defects in the Head and Neck.

BACKGROUND: Small recalcitrant defects of the mandible and maxilla may be secondary to tumor, trauma, infection, and congenital origin. Vascularized bone grafting has been shown to effectively manage these defects; however, donor sites are limited. The vascularized medial femoral condyle (MFC) provides adequate cortical cancellous bone with the option of a skin island, consistent anatomy, and minimal donor site morbidity. This article outlines the use of the MFC flap for maxillomandibular reconstruction. METHODS: A retrospective chart review of patients who required segmental maxillomandibular reconstruction with the MFC flap was conducted. A total of 9 patients (5 men and 5 women) with an average age of 45.3 years were identified. The etiology of the defects, flap sizes, and postoperative outcomes were recorded. RESULTS: Three patients had osteoradionecrosis of the neomandible after irradiation of the free fibula reconstruction, 3 patients had defects after cancer extirpation (1 mandible, 2 maxillary), 1 patient had a maxillary defect from trauma, and 2 patients had a residual cleft palate defect. All defects failed initial treatment with nonvascularized bone grafts. The average dimensions of the MFC flaps were 1.2 × 2.5 × 4 cm. Two of 9 flaps included a skin island. Eight flaps survived completely, but 1 patient suffered from flap failure requiring debridement and resulted in an oroantral fistula. Four patients received endosseous dental implants. Average time to union was 6.7 months, and average time to implant was 6.75 months. The average follow-up time was 24.9 months. CONCLUSIONS: The MFC flap is useful in the reconstruction of small segmental maxillomandibular defects and for the salvage of a neomandible after osteoradionecrosis. The MFC flap provides a reliable platform for endosseous dental implants and serves as an alternative source of vascularized bone reconstruction in the head and neck.

Pediatric Mandibular Central Giant Cell Granuloma: Neoadjuvant Immunotherapy to Minimize Surgical Resection.

ABSTRACT: Central giant cell granuloma (CGCG) is a relatively uncommon benign bony lesion accounting for approximately 7% of all non-neoplastic lesions of the jaw. The clinical behavior of CGCG can vary from a slow-growing, painless lesion to fast-growing and locally destructive. When such a lesion involves the mandible, this can be quite debilitating for the patient, inhibiting oral intake and requiring an extensive resection and bone graft reconstruction. The authors present a case of effectively decreasing the surgical morbidity associated with a large and rapidly growing CGCG of the mandible in a pediatric patient. Neoadjuvant immunotherapy with denosumab (human monoclonal antibody) facilitated treatment of the tumor without the need for a large resection which would have otherwise necessitated a vascularized bony mandibular reconstruction. Consideration of neoadjuvant medical management of CGCG as the primary treatment is advocated.

Medial approach to the peroneal vessels as recipients for free flap reconstruction of the leg.

The anatomic variation in the branching pattern of the popliteal vessel has been well-established. Little has been written in the literature regarding recipient vessel selection for microvascular reconstruction in the lower extremity as it pertains to aberrant vascular anatomy. We present the case of a 57-year-old male patient who sustained a closed right lower extremity pilon fracture in a motor vehicle accident. The patient was initially treated with external fixation, which was followed by definitive open reduction and internal fixation 3 weeks later. Over the next 2 weeks, the patient developed skin ischemia of the anterior ankle. A free-tissue transfer was planned. A digital subtraction angiogram revealed absence of the posterior tibial (PT) vessels and an aberrant course of the peroneal (PR) artery. In the operating room, the medial distal leg was explored for the PT vessels, which were severely hypoplastic. Given the close proximity of the PR vessels, the dissection was extended proximally to assess these vessels for microvascular anastomosis. They were found to be suitable. A parascapular flap was harvested and transferred to the right leg wound without any significant stretch on the vessels for soft tissue coverage. The flap demonstrated excellent inflow and outflow, and the leg and foot remained well perfused. The patient's postoperative course was uncomplicated. The technique of exposing the peroneal vessels for microvascular anastomosis via a medial approach is described. This technique is an excellent option to have available when aberrant anatomy precludes the use more commonly utilized vessels.

Traumatic Cranio-Orbital Injury: Reconstruction Using Extraocular Muscles.

Cranio-orbital trauma is an uncommon yet devastating injury, especially one in the setting of a high-energy gunshot wound. Such injuries were historically reported in the setting of military conflict, and are associated with vision-threatening complications, often resulting in anophthalmos. The authors report a case of a self-inflicted gunshot wound to the eye, which requires orbital enucleation with exposed frontal lobe dura. To address the exposed dura, the extraocular muscles were utilized from the enucleation procedure to cover the defect in the acute setting prior to final staged reconstruction.

Lower-limb reconstruction with chimeric flaps: The quad flap.

Early soft-tissue coverage is critical for treating traumatic open lower-extremity wounds. As free-flap reconstruction evolves, injuries once thought to be nonreconstructable are being salvaged. Free-tissue transfer is imperative when there is extensive dead space or exposure of vital structures such as bone, tendon, nerves, or blood vessels. We describe 2 cases of lower-extremity crush injuries salvaged with the quad flap. This novel flap consists of parascapular, scapular, serratus, and latissimus dorsi free flaps in combination on one pedicle. This flap provides the large amount of soft-tissue coverage necessary to cover substantial defects from skin degloving, tibia and fibula fractures, and soft-tissue loss. In case 1, a 51-year-old woman was struck by an automobile and sustained bilateral tibia and fibula fractures, a crush degloving injury of the left leg, and a right forefoot traumatic amputation. She underwent reconstruction with a contralateral quad free flap. In case 2, a 53-year-old man sustained a right tibia plateau fracture with large soft-tissue defects from a motorcycle accident. He had a crush degloving injury of the entire anterolateral compartment over the distal and lower third of the right leg. The large soft-tissue defect was reconstructed with a contralateral quad flap. In both cases, the donor site was closed primarily and without early flap failures. There was one surgical complication, an abscess in case 2; the patient was taken back to the operating room for débridement of necrotic tissue. There have been no long-term complications in either case. Both patients achieved adequate soft-tissue coverage, avoided amputation, and had satisfactory aesthetic and functional outcomes. With appropriate surgical technique and patient selection, the quad-flap technique is promising for reconstructing the lower extremity.

Patient-specific polyetheretherketone implants for repair of craniofacial defects.

BACKGROUND: Large cranial defects represent reconstructive challenges. Polyetheretherketone (PEEK) implants are preoperatively tailored to the exact size of the defect and exhibit an excellent combination of strength, durability, and environmental resistance. This study presents our experience with patient-specific PEEK implants with computer modeling. METHODS: A retrospective chart review was conducted on all patients who underwent cranioplasty treated by a PEEK implant between 2007 and 2012. Analysis of the preoperative and perioperative data as well as outcome analysis was performed. RESULTS: A total of 11 patients were included. Mean age was 46 years. The indication for cranioplasty was bone flap infection and subsequent removal in 8 patients, traumatic bone loss in 2 patients, and acquired defect due to cancer resection in 1 patient. The mean time to PEEK cranioplasty since the patient's last operation was 16 months. The mean defect size was 74 cm(2). The mean surgical blood loss was 124 mL. The mean length of stay was 3 days. Complications included 1 postoperative bleeding that required reoperation, but the PEEK implant was successfully salvaged. The mean time to follow-up was 6 months. CONCLUSIONS: Use of patient-specific PEEK implants is a good alternative for alloplastic cranioplasty. It is associated with low morbidity as reported in our series, with additional advantages including strength, stiffness, durability, and inertness. It would be beneficial to assess the longer-term outcomes; however, it appears at first glance that PEEK implants show great promise in calvarial reconstruction.

Airway risk associated with patients in halo fixation.

Background: The halo fixation device introduces a significant obstacle for clinicians attempting to secure a definitive airway in trauma patients with cervical spine injuries. The authors sought to determine the airway-related mortality rate of adult trauma patients in halo fixation requiring endotracheal intubation. Methods: This study was a retrospective chart review of patients identified between 2007 and 2012. Only adult trauma patients who were intubated while in halo fixation were included in the study. Results: A total of 46 patients underwent 60 intubations while in halo. On five occasions, (8.3%) patients were unable to be intubated and required an emergent surgical airway. Two (4.4%) of the patients out of our study population died specifically due to airway complications. Elective intubations had a failure rate of 5.8% but had no related permanent morbidity or mortality. In contrast to that, 25% of non-elective intubations failed and resulted in the deaths of two patients. The association between mortality and non-elective intubations was statistically highly significant (P = 0.0003). Conclusion: The failed intubation and airway-related mortality rates of patients in halo fixation were substantial in this study. This finding suggests that the halo device itself may present a major obstacle in airway management. Therefore, heightened vigilance is appropriate for intubations of patients in halo fixation.

Laminectomy for acute transverse sacral fractures with compression of the cauda equina: A neurosurgical perspective.

Introduction: Optimal management of transverse sacral fractures (TSF) remains inconclusive. These injuries may present with neurological deficits including cauda equina syndrome. We present our series of laminectomy for acute TSF with cauda equina compression. Methods: This was a retrospective chart review of all patients that underwent sacral laminectomy for treatment of cauda equina compression in acute TSF at our institution between 2007 through 2023. Results: A total of 9 patients (5 male and 4 female) underwent sacral laminectomy to decompress the cauda equina in the setting of acute high impact trauma. Surgeries were done early within a mean time of 5.9 days. All but one patient had symptomatic cauda equina syndrome. In one instance surgery was applied due to significant canal stenosis present on imaging in a patient with diminished mental status not allowing proper neurological examination. Torn sacral nerve roots were repaired directly when possible. All patients regained their neurological function related to the sacral cauda equina on follow up. The rate of surgical site infection (SSI) was 33%. Conclusion: Acute early sacral laminectomy and nerve root repair as needed was effective in recovering bowel and bladder function in patients after high impact trauma and TSF with cauda equina compression. A high SSI rate may be reduced by delaying surgery past 1 week from trauma, but little data exists at this time for clear recommendations.

Lower branches of the facial nerve.

Various aesthetic procedures have been developed over the past several decades for facial rejuvenation. One of the parallel goals is protection of vital structures such as the facial nerve. In this study, 10 cadaveric hemifacial dissections were performed, and the course of the lower portion of the facial nerve was studied with specific attention addressed toward the three-dimensional location of the nerve as it relates to the usual superficial tissue planes that are dissected during the course of an open facial rejuvenation procedure. The locations of the nerve as it runs within the different planes in addition to some suggestions to avoid injury to the lower branches of the facial nerve are discussed.

Brown-Sequard syndrome associated with hangman fracture after blunt trauma: A case report.

Background: The association of Brown-Sequard syndrome (BSS) and hangman fracture (HF) is rarely reported. Case Description: We present a case of a 28-year-old female with a HF sustained after a motor vehicle accident and BSS. Diagnosis was established based on typical loass of motor function ipsilaterally and loss of pain and temperature sensation contralaterally. Furthermore, magnetic resonance imaging delineated the location of the injury to the right side of the spinal cord at cervical level 2. Near-complete neurological recovery was achieved after anterior fusion and fixation at cervical level 2-3 after 8 months of follow-up. Conclusion: HF from blunt trauma can be directly associated with BSS. Surgery was effective and associated with a near-complete resolution of symptoms.

Blunt traumatic posterior cord syndrome.

INTRODUCTION: Posterior cord syndrome (PCS) is rare and insufficiently assessed in the International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI). CASE PRESENTATION: A 39-year-old male was involved in a motorcycle collision and presented with paresthesia of the entire body, neck pain, subjective right arm weakness, and loss of position sense in all extremities. Imaging of the cervical spine revealed fractures of the upper cervical spine including a teardrop fracture and hangman fracture. Patient underwent anterior cervical interbody fusion and plating and halo orthosis. He ultimately regained near full function. Follow-up imaging clearly depicted the traumatic lesion to the level of the posterior spinal cord. DISCUSSION: PCS is uncommon, but may be underdiagnosed. We would like to emphasize the importance of a full neurological exam in order to properly diagnose and manage patients with PCS. Our case is unique since we were able to anatomically delineate the focus of spinal cord injury to the posterior column on follow up MRI at 10 months. Therefore, a delayed MRI obtained sub-acutely may facilitate the anatomical diagnosis of PCS.

Location of Traumatic Cranial Epidural Hematoma Correlates with the Source of Hemorrhage: A 12-Year Surgical Review.

BACKGROUND: Epidural hematoma (EDH) can result in a catastrophic outcome of traumatic brain injury. Current management guidelines do not consider the source of hemorrhage in decision making. The purpose of this study was to examine the relationship between EDH location and the source of hemorrhage. METHODS: We report retrospectively reviewed, prospectively obtained surgical data of patients with acute traumatic cranial EDH treated between 2007 and 2018. Computed tomography (CT) scans were used to categorize EDH location as lateral or medial. The source of hemorrhage was identified intraoperatively by a single surgeon. RESULTS: Overall, of 92 evacuated EDHs (in 87 patients), 71 (77.2%) were in the lateral location. Arterial bleeding was the cause of EDH in 63.4% of the lateral EDHs and 9.2% of the medial EDHs (P < 0.0001). In the cases where surgery was done primarily to treat EDH, 65.3% had an arterial bleed source (P < 0.0001). In those treated for primary reasons other than EDH evacuation, 75% had a venous bleed source (P = 0.002). CONCLUSIONS: The location of EDH correlates with the source of hemorrhage. The decision to operate on EDH may be influenced by this factor.

Pyoderma gangrenosum confined to the irradiated chest wall of the reconstructed breast.

Pyoderma gangrenosum (PG) is a diagnosis of exclusion worsened by surgical debridement. This report presents two atypical manifestations of PG in the reconstructed breast, whereby the disease is only confined to the irradiated chest wall tissue bed, sparing the abdominal donor sites and the contralateral reconstructed breast.

The Utility of 5-Aminolevulinic Acid for Microsurgical Resection of Meningiomas.

Fluorescence-guided resection of brain tumors using 5-aminolevulinic acid (5-ALA) has been established for high-grade gliomas. Recently, its application for the resection of low grade tumors and benign lesions including meningioma has been suggested in the literature.1 Achieving a Simpson grade I resection in meningioma surgery is associated with a lower rate of recurrence.2,3 Although meningiomas are mostly benign and well-circumscribed lesions, they can be locally aggressive, invading brain parenchyma and other critical structures. In these cases, 5-ALA-guided resection may help maximize the extent of tumor resection and limit disruption of normal structures. In this video, we present 3 cases demonstrating the use of 5-ALA-induced fluorescence to alleviate 3 specific challenges in meningioma resection: 1) to aid visualization with a minimally invasive approach, 2) to distinguish recurrent tumor from scar tissue from prior treatments, and 3) to ensure that no viable tumor cells remain on the surface of a critical artery. The first patient is a 60-year-old woman who was found to have an incidental left sphenoid wing meningioma on magnetic resonance imaging. We elected for an extended lateral orbital craniotomy through a transpalpebral approach. The second patient is a 72-year-old man with recurrent left occipital parietal meningioma who underwent a parietal craniotomy. The third case was a 62-year-old woman with a foramen magnum meningioma encircling the left vertebral artery. These cases demonstrate the utility of 5-ALA in a variety of challenges associated with resection of meningiomas (Video 1).

Natural History of a Patient with Sacral Chordoma: Case Report and Literature Review.

BACKGROUND: Chordomas are rare, slow-growing, locally aggressive, malignant tumors of the spine. Chordomas are conventionally treated with surgical resection with or without radiation. There is an absence of literature documenting the natural history of a primary sacral chordoma. CASE DESCRIPTION: A 65-year-old man presented with rectal pain, constipation, urinary and fecal incontinence, S1 radiculopathy, and a palpable rectal mass. A needle biopsy confirmed the pathologic diagnosis of sacral chordoma. The patient declined to have surgery because of the surgical risks involved. He was managed conservatively with supportive care only. The patient was routinely followed in clinic and had a subjective and objective excellent quality of life with adequate pain management. Meanwhile, his neurologic status did not deteriorate. During follow-up, some posterolateral aspects of the chordoma regressed. However, the bulk of the lesion continued to slowly progress. The patient survived for 7.5 years. He eventually succumbed to urosepsis and new-onset peritoneal metastasis. CONCLUSIONS: To our knowledge, the patient is the only documented case in the literature of an untreated biopsy-proven sacral chordoma. The patient's tumor was intended for resection, and therefore comparable with data from treated chordomas. The patient's survival is similar to the median survival in treated chordomas. The patient's survival was despite negative prognosticators, such as advanced age of the patient and high sacral location above S2.

Atlanto-Occipital Transarticular Screw Fixation for the Treatment of Traumatic Occipitocervical Instability in the Pediatric Population.

BACKGROUND: Atlanto-occipital transarticular screw fixation (AOTSF) has rarely been reported for fixation of the craniovertebral junction (CVJ). METHODS: A retrospective chart review of all pediatric patients (less than 18 years of age) with an attempt of AOTSF for fixation of traumatic CVJ instability was conducted. RESULTS: A total of 4 patients (2 boys and 2 girls; ages 2, 3, 5, and 8 years) who suffered from acute traumatic CVJ instability managed during 2007-2018 underwent an attempted AOTSF. In 2 patients, this method was technically successful. In the other 2 instances, we were not able to engage the screw into the occipital condyle. These were converted to standard occipital plate, rod, and screw fixation. All were placed in a halo subsequently for a minimum of 3 months. Three patients were fused at last follow-up (range, 17-48 months). One patient after successful AOTSF did not fuse. There were no surgical complications or revision procedures. CONCLUSIONS: AOTSF was feasible in half of pediatric patients suffering from traumatic CVJ instability. Therefore, intraoperative salvage options and strategies should be on hand readily. In the pediatric population, where bony anatomy may pose challenges to fixation, this technique may offer a viable first-line option in selected cases, despite the overall modest success rate.

Proposed classification for the transbasal approach and its modifications.

The transbasal approach offers extradural exposure of the anterior midline skull base transcranially. It can be used to treat a variety of conditions, including trauma, craniofacial deformity, and tumors. This approach has been modified to enhance basal access. This article reviews the principle differences among modifications to the transbasal approach and introduces a new classification scheme. The rationale is to offer a uniform nomenclature to facilitate discussion of these approaches, their indications, and related issues.
