    (Silverchair, 2019-10-10) Fancy, Tanya; Huang, Andrew T.; Kass, Jason I.; Lamarre, Eric D.; Tassone, Patrick; Mantravadi, Avinash V.; Alwani, Mohamedkazim M.; Subbarayan, Rahul S.; Bur, Andrés M.; Worley, Mitchell L.; Graboyes, Evan M.; McMullen, Caitlin P.; Azoulay, Ofer; Wax, Mark K.; Cave, Taylor B.; Al-khudari, Samer; Abello, Eric H.; Higgins, Kevin M.; Ryan, Jesse T.; Orzell, Susannah C.; Goldman, Richard A.; Vimawala, Swar; Fernandes, Rui P.; Abdelmalik, Michael; Rajasekaran, Karthik; L’Esperance, Heidi E.; Kallogjeri, Dorina; Rich, Jason T.; Otolaryngology -- Head and Neck Surgery, School of Medicine
    Importance Data regarding outcomes after major head and neck ablation and reconstruction in the growing geriatric population (specifically ≥80 years of age) are limited. Such information would be extremely valuable in preoperative discussions with elderly patients about their surgical risks and expected functional outcomes. Objectives To identify patient and surgical factors associated with 30-day postoperative complications, 90-day mortality, and 90-day functional decline; to explore whether an association exists between the type of reconstructive procedure and outcome; and to create a preoperative risk stratification system for these outcomes. Design, Setting, and Participants This retrospective, multi-institutional cohort study included patients 80 years or older undergoing pedicle or free-flap reconstruction after an ablative head and neck surgery from January 1, 2015, to December 31, 2017, at 17 academic centers. Data were analyzed from February 1 through April 20, 2019. Main Outcomes and Measures Thirty-day serious complication rate, 90-day mortality, and 90-day decline in functional status. Preoperative comorbidity and frailty were assessed using the American Society of Anesthesiologists classification, Adult Comorbidity Evaluation–27 score, and Modified Frailty Index. Multivariable clustered logistic regressions were performed. Conjunctive consolidation was used to create a risk stratification system. Results Among 376 patients included in the analysis (253 [67.3%] men), 281 (74.7%) underwent free-flap reconstruction. The median age was 83 years (range, 80-98 years). A total of 193 patients (51.3%) had 30-day serious complications, 30 (8.0%) died within 90 days, and 36 of those not dependent at baseline declined to dependent status (11.0%). Type of flap (free vs pedicle, bone vs no bone) was not associated with these outcomes. Variables associated with worse outcomes were age of at least 85 years (odds ratio [OR] for 90-day mortality, 1.19 [95% CI 1.14-1.26]), moderate or severe comorbidities (OR for 30-day complications, 1.80 [95% CI, 1.34-2.41]; OR for 90-day mortality, 3.33 [95% CI, 1.29-8.60]), body mass index (BMI) of less than 25 (OR for 30-day complications, 0.95 [95% CI, 0.91-0.99]), high frailty (OR for 30-day complications, 1.72 [95% CI, 1.10-2.67]), duration of surgery (OR for 90-day functional decline, 2.94 [95% CI, 1.81-4.79]), flap failure (OR for 90-day mortality, 3.56 [95% CI, 1.47-8.62]), additional operations (OR for 30-day complications, 5.40 [95% CI, 3.09-9.43]; OR for 90-day functional decline, 2.94 [95% CI, 1.81-4.79]), and surgery of the maxilla, oral cavity, or oropharynx (OR for 90-day functional decline, 2.51 [95% CI, 1.30-4.85]). Age, BMI, comorbidity, and frailty were consolidated into a novel 3-tier risk classification system. Conclusions and Relevance Important demographic, clinical, and surgical characteristics were found to be associated with postoperative complications, mortality, and functional decline in patients 80 years or older undergoing major head and neck surgery. Free flap and bony reconstruction were not independently associated with worse outcomes. A novel risk stratification system is presented.

    Dynamic Reconstruction of Facial Paralysis in Craniofacial Microsomia
    (Wolters Kluwer, 2022-04) Zuo, Kevin J.; Heinelt, Martina; Ho, Emily S.; Forrest, Christopher R.; Zuker, Ronald M.; Borschel, Gregory H.; Medicine, School of Medicine
    BACKGROUND: Craniofacial microsomia is associated with maxillomandibular hypoplasia, microtia, soft-tissue deficiency, and variable severity of cranial nerve dysfunction, most often of the facial nerve. This study evaluated the incidence of facial paralysis in patients with craniofacial microsomia and outcomes after free functioning muscle transfer for dynamic smile reconstruction. METHODS: A single-center, retrospective, cross-sectional study was performed from 1985 to 2018 to identify pediatric patients with craniofacial microsomia and severe facial nerve dysfunction who underwent dynamic smile reconstruction with free functioning muscle transfer. Preoperative and postoperative facial symmetry and oral commissure excursion during maximal smile were measured using photogrammetric facial analysis software. RESULTS: This study included 186 patients with craniofacial microsomia; 41 patients (21 male patients, 20 female patients) had documented facial nerve dysfunction (22 percent) affecting all branches (51 percent) or the mandibular branch only (24 percent). Patients with severe facial paralysis (n = 8) underwent smile reconstruction with a free functioning muscle transfer neurotized either with a cross-face nerve graft (n = 7) or with the ipsilateral motor nerve to masseter (n =1). All patients achieved volitional muscle contraction with improvement in lip symmetry and oral commissure excursion (median, 8 mm; interquartile range, 3 to 10 mm). The timing of orthognathic surgery and facial paralysis reconstruction was an important consideration in optimizing patient outcomes. CONCLUSIONS: The authors' institution's incidence of facial nerve dysfunction in children with craniofacial microsomia is 22 percent. Free functioning muscle transfer is a reliable option for smile reconstruction in children with craniofacial microsomia. To optimize outcomes, a novel treatment algorithm is proposed for craniofacial microsomia patients likely to require both orthognathic surgery and facial paralysis reconstruction.

    Resection of a Catecholamine-Elaborating Retroperitoneal Paraganglioma Invading the Inferior Vena Cava
    (Hindawi Publishing Corporation, 2014-12-28) Mannina, E. M.; Xiong, Z.; Self, R.; Kandil, E.; Department of Radiation Oncology, IU School of Medicine
    Paragangliomas are rare tumors originating outside of the adrenal medulla which can be associated with catecholamine secretion or mass effect, one of which typically leads to their discovery. The differences between these tumors and traditional intra-adrenal pheochromocytomas are a subject of recent investigations. Standard of care therapy is medical management and surgical resection of the tumor. When tumors are biochemically active, medical optimization of the autonomic nervous system is a critical component to a safe, definitive resection. Tumors arising in the retroperitoneum present technical challenges for the surgeon as they are often large and difficult to access, making an oncologic resection much more difficult. Lastly, these tumors are mostly benign and rarely invade adjacent structures—an operative finding not always predicted by preoperative imaging—which, if present, adds significant complexity and risk to the resection. A case illustrating these challenges in the management of a biochemically active retroperitoneal paraganglioma invading the inferior vena cava follows.

    Using Big Data to Assess Legitimacy of Plastic Surgery Information on Social Media
    (Oxford Academic, 2022-01) Chartier, Christian; Lee, Justine C.; Borschel, Gregory; Chandawarkar, Akash; Surgery, School of Medicine
    Background The proliferation of social media in plastic surgery poses significant difficulties for the public in determining legitimacy of information. This work proposes a system based on social network analysis (SNA) to assess the legitimacy of information contributors within a plastic surgery community. Objectives The aim of this study was to quantify the centrality of individual or group accounts on plastic surgery social media by means of a model based on academic plastic surgery and a single social media outlet. Methods To develop the model, a high-fidelity, active, and legitimate source account in academic plastic surgery (@psrc1955, Plastic Surgery Research Council) appearing only on Instagram (Facebook, Menlo Park, CA) was chosen. All follower-followed relationships were then recorded, and Gephi (https://gephi.org/) was used to compute 5 different centrality metrics for each contributor within the network. Results In total, 64,737 unique users and 116,439 unique follower-followed relationships were identified within the academic plastic surgery community. Among the metrics assessed, the in-degree centrality metric is the gold standard for SNA, hence this metric was designated as the centrality factor. Stratification of 1000 accounts by centrality factor demonstrated that all of the top 40 accounts were affiliated with a plastic surgery residency program, a board-certified academic plastic surgeon, a professional society, or a peer-reviewed journal. None of the accounts in the top decile belonged to a non–plastic surgeon or non-physician; however, this increased significantly beyond the 50th percentile. Conclusions A data-driven approach was able to identify and successfully vet a core group of interconnected accounts within a single plastic surgery subcommunity for the purposes of determining legitimate sources of information.
