Free Flap Donor-Site Complications and Management.

Free flap harvest will occasionally result in donor-site complications and morbidity. Most of these complications are managed simply without producing lingering effects on activities of daily living. However, some patients will sustain limb weakness, gait issues, chronic pain, and nonhealing wounds. Frank preoperative discussion between surgeon and patient is essential to maximize postoperative outcome and manage expectations. Fastidious surgical technique will help minimize the risks of hematoma, seroma, and infection, while newer techniques can help prevent some issues with wound healing, limb weakness, and sensory changes. In this article, we describe the rates of common and rare complications at free flap donor sites, as well as techniques to prevent and manage them.

Metastatic Prostate Cancer Involving the Sphenoid Sinus and Mandible.

Prostate cancer is the third most leading cause of cancer in men in the United States. Although expected metastatic spread to bone, liver, and lymph nodes are often monitored, there are other rare presentations that can occur. This case report demonstrates a rare presentation of prostate cancer spreading to the paranasal sinuses and orbit. Not only did this case have an atypical presentation mimicking infection, the diagnosis was also only achieved through pathological evaluation after an endoscopic examination and biopsy. This case demonstrates the importance of a low threshold for endoscopic examinations in uncertain sinonasal presentations, and consistent biopsies when performing endoscopic examinations.

Metastatic breast cancer masquerading as a pituitary macroadenoma: A case report.

The purpose of this manuscript is to report a case of symptomatic breast cancer metastasis to the pituitary gland, a described yet exceedingly rare phenomenon. A 52-year-old woman with a known history of stage-IV breast cancer treated 3 years prior with chemotherapy presented to the emergency department with 2 weeks of right-sided periorbital headache and 1 week of right-sided ptosis. Magnetic resonance imaging showed a 1.9 cm × 2.8 cm × 2.8 cm mass in the pituitary with mass effect on the right optic chiasm. Endocrine laboratory studies were largely normal, including prolactin, thyroid-stimulating hormone, insulin-like growth factor, and a minimally decreased cortisol. She underwent endoscopic transnasal transsphenoidal resection 4 days later to remove the mass without complication. Postoperative pathologic studies were positive for breast cancer metastasis, and she was subsequently started on adjuvant radiation and oral chemotherapy. While breast cancer metastases to the sella have been described in the literature before, symptomatic spread to the pituitary represents a small percentage of all breast cancer metastases, and we thus feel is worthy of further discussion.

A Guide to Facial Trauma Triage and Precautions in the COVID-19 Pandemic.

COVID-19 is an emerging viral illness that has rapidly transmitted throughout the world. Its impact on society and the health care system has compelled hospitals to quickly adapt and innovate as new information about the disease is uncovered. During this pandemic, essential medical and surgical services must be carried out while minimizing the risk of disease transmission to health care workers. There is an elevated risk of COVID-19 viral transmission to health care workers during surgical procedures of the head and neck due to potential aerosolization of viral particles from the oral cavity/naso-oropharynx mucosa. Thus, patients with facial fractures pose unique challenges to the variety of injuries and special considerations, including triaging injuries and protective measures against infection. The proximity to the oral cavity/naso-oropharyngeal mucosa, and potential for aerosolization of secretions containing viral particles during surgical procedures make most patients undergoing operative interventions for facial fractures high risk for COVID-19 transmission. Our proposed algorithm aims to balance patient care with patient/medical personnel protection as well as judicious health care utilization. It stratifies facial trauma procedures by urgency and assigns a recommended level of personal protective equipment, extreme or enhanced, incorporating current best practices and existing data on viral transmission. As this pandemic continues to evolve and more information is obtained, the protocol can be further refined and individualized to each institution.

Xanthogranulomatous Sialadenitis, an Uncommon Reactive Change is Often Associated with Warthin's Tumor.

Xanthogranulomatous sialadenitis (XGS) is rare in salivary glands and only reported in the literature as single cases. Here we report a cohort of four cases with XGS and summarize the clinicopathologic features of these cases. All four patients had persistent mass lesions concerning for neoplasm. In two patients (patient 1 and 3), the initial fine needle aspirations (FNAs) contained oncocytic cells consistent with or suspicious for Warthin's tumor, but follow-up FNAs showed only inflammation and/or debris indicating tumor infarction after FNA. All patients eventually had surgical resection. Histologically, all cases contained abundant macrophages with necrosis and fibroblastic proliferation. Warthin's tumor with a grossly identifiable tumor nodule (0.7 cm) was noted in patient 1 and a microscopic focus (0.2 cm) of Warthin's tumor was identified in patient 3. No identifiable tumor was observed in patient 2 and 4. There are a total of 10 XGS cases in the literature (including four from this series) and Warthin tumor was identified in 50% of reported cases of XGS, suggesting that XGS is an uncommon reactive process to spontaneous or procedure-induced infarction of Warthin tumor. As a diagnostic mimicker for malignancy, a thorough examination and generous sampling of surgical resection specimen is warranted, although a benign salivary gland neoplasm, commonly Warthin's tumor, is often identified.

Intraoperative Imaging Changes Management in Orbital Fracture Repair.

PURPOSE: Intraoperative imaging is gaining widespread use in the management of facial fracture repair. The aim of this study was to determine whether intraoperative imaging changes the management of orbital fracture repair. MATERIALS AND METHODS: A retrospective case series was performed of all cases of orbital fracture repair from 2008 to 2015 in which the intraoperative O-arm was used at Regions Hospital (St Paul, MN), a level I trauma center. The primary outcome variable was a change in management, ranging from orbital plate repositioning to proceeding with orbital floor exploration. RESULTS: The study sample was composed of 101 patients with a mean age of 40 ± 15 years. Approximately 75% (76 of 101) of patients were male and 25% (25 of 101) were female. All cases were secondary to assault, motor vehicle accident, fall, or gunshot wounds. Use of the O-arm resulted in a change in management in 44% (44 of 101) of cases. In 48% (21 of 44) of these cases in which intraoperative imaging resulted in a change in management, the orbital plate was repositioned to optimize repair. In 16% (7 of 44) of these cases, the orbital plate was exchanged for a different size or type of plate. In 7% (3 of 44) of these cases, the orbital plate was reshaped by bending to improve contour for the repair. In another 7% (3 of 44) of these cases, the orbital plate was reshaped by trimming the plate to optimize the length or width of the plate for repair. In 7% of these cases, the orbital floor required exploration based on intraoperative imaging. In 5% of these cases, the orbital floor was found to be adequately reduced after zygoma reduction based on intraoperative imaging and did not require exploration. CONCLUSIONS: Use of intraoperative imaging allows the surgeon to make real-time changes in operative management ranging from orbital plate repositioning to deciding whether to proceed with orbital floor exploration. This not only allows for immediate optimization of repair but also could decrease the need for revision procedures, thus decreasing patient morbidity and improving patient outcomes.

Genioglossal Advancement, Hyoid Suspension, Tongue Base Radiofrequency, and Endoscopic Partial Midline Glossectomy for Obstructive Sleep Apnea.

Surgical intervention for obstructive sleep apnea (OSA) is a complex topic. The discussion involves intricate procedures targeting specific areas of the upper airway. Because of the wide variety of physiologic and anatomic causes of this disorder it is important to tailor the treatment to offer the patient the best possible outcome. Genioglossus, hyoid, and tongue base procedures should be considered among theses treatment options.

Computer-aided stereolithography for presurgical planning in fibula free tissue reconstruction of the mandible.

INTRODUCTION: Computer-aided imaging has facilitated presurgical modeling for free tissue mandibular reconstruction. The purpose of this study is to illustrate the utility of preoperative virtual surgical planning in fibula reconstruction of the mandible. METHODS: Eight patients, age 17 to 72 years, treated between November 2009 and January 2011 were reviewed. Each required segmental resection and reconstruction of the mandible and were managed with presurgical virtual planning. RESULTS: Our series includes five cases of squamous cell carcinoma (SCCA), one case of osteoradionecrosis (ORN), one leiomyosarcoma, and one odontogenic myxoma. All patients underwent a segmental resection of the mandible 5 to 14 cm in size (average 8 cm). In each case, prefabricated guides for segmental mandibulectomy and fibula osteotomy were employed and resulted in simplification of bony inset and reduced need for "fine tuning" of fibula segments. CONCLUSIONS: Virtual surgical planning fosters multidisciplinary communication and provides accurate presurgical planning. This allows seamless reconstruction in patients requiring mandibular reconstruction via fibula free tissue transfer. The combination of mandibular and fibular cutting guides and templates allows for a precise and efficient surgical reconstruction. In our experience, this technology is most useful in the reconstruction of large mandibular defects requiring large reconstruction plates and multiple fibular osteotomies.

A comparison of anterior vs posterior isolated mandible fractures treated with intermaxillary fixation screws.

OBJECTIVE: To compare complication rates after use of intermaxillary fixation (IMF) bone screws for anterior (ie, symphyseal/parasymphyseal) and posterior (ie, body and angle) mandible fractures. METHODS: A retrospective analysis of isolated mandible fractures treated with intraoperative IMF bone screws at 2 major level 1 trauma centers within the Department of Otolaryngology-Head and Neck Surgery at the University of Minnesota. From January 1, 2003, through January 31, 2006, we accrued 53 patients with 67 isolated mandible fractures treated with intraoperative IMF bone screws. These patients had at least 6 weeks of follow-up. RESULTS: Twenty-one patients had anterior mandible fractures and 32 had posterior mandible fractures. In the anterior group, there was 1 incident of wound dehiscence, resulting in a total complication rate of 5%. In the posterior fracture group, there was 1 infection (3%), 4 malunions/malocclusions (12%), and 1 nonunion (3%), for an overall complication rate of 19%. The difference between groups for malocclusion rates (12% vs 0%) was significant (P < .001). CONCLUSIONS: The IMF bone screw system has a superior speed and safety profile. It produces better occlusion results in anterior mandible fractures and might have a lower overall complication rate compared with arch bars. Given this, IMF bone screws are the preferred modality of intermaxillary fixation in properly selected mandible fractures.

The versatility of distraction osteogenesis in craniofacial surgery.

OBJECTIVES: To review our preliminary results using distraction osteogenesis for the correction of craniofacial deformities and to determine its role in treating anatomic deformities and functional deficits relative to conventional craniofacial surgery. DESIGN AND SETTING: Retrospective clinical review; tertiary care center. METHODS: Twenty-four consecutive patients were treated with distraction osteogenesis during a 34-month period. Outcomes were compared with preexisting anatomic deformities and functional deficits using records of clinical assessments, photodocumentation, diagnostic imaging, and treatment planning aids. MAIN OUTCOME MEASURES: Distraction achieved vs planned distraction based on clinical and radiographic assessment, clinical status of functional deficits before and after treatment, and objective rating of aesthetic improvement. CONCLUSIONS: Preliminary results demonstrated good-to-excellent outcome in correcting facial skeletal deformity in 80% of patients. Functional outcomes included resolution or significant improvement of upper airway obstruction in 13 of 14 patients and correction of corneal exposure for all 5 patients with preexisting exorbitism. Correction of malocclusion was less reliable. Problems related to the distraction devices, including failure of the advancement mechanism and fixation, were the most prevalent complications. Distraction osteogenesis represents an exciting new development in craniofacial surgery with several potential benefits, including less invasive surgery, the ability for earlier intervention, and the potential for correction of more severe deformities with improved posttreatment stability. The exact role of distraction osteogenesis relative to conventional techniques requires ongoing assessment.
