- Abstract
Background: Advancements in digital cameras and the advent of smartphones have magnified the importance of clinical photography in facial plastic surgery. Here, we aim to examine the effect of different camera types, focal lengths, and distances from subjects on facial distortion. Methods: Twelve subjects underwent a series of frontal photographs using a smartphone camera and a full‐frame digital single‐lens reflex camera. Photos were captured at six distances from the subject. Seven focal lengths were used at each distance for the full‐frame camera. Measurements of facial landmarks were made for each photo, with those made at 60 inches using the full‐frame camera considered the gold standard and used for comparison. Results: Distortion of facial features using the full‐frame camera occurred when photos were captured 8 inches away using short focal lengths. A 12%–19% increase in vertical stretching of the midface occurred when using focal lengths of 24, 35, and 50 mm (p < 0.05 for all). The same features were distorted when a smartphone camera was used at 8 inches (18% increase, p < 0.01) and 12 inches (12% increase, p < 0.03). Conclusions: Distortion of midfacial features using both smartphones and full‐frame cameras occurs with short, 'selfie' distances between the camera and subject.

- Abstract
Objectives/Hypothesis: Dermal filler (DF) is a widely used nonsurgical option for facial rejuvenation with a rapidly expanding market. Physician payments by DF industry leaders have yet to be characterized. We sought to investigate trends in physician‐industry payments by DF companies over 6 years. Differences in payments based on physician specialty and time were characterized. Study Design: Database review. Methods: The Open Payments Database was queried from 2013 to 2018. Payments made by the three largest DF companies by market share to otolaryngologists, plastic surgeons, and dermatologists were analyzed. Total dollars paid, number of payments made, type of payments made, and total number of specialists paid were recorded. One‐way ANOVA was used for statistical analysis. Results: Otolaryngologists, plastic surgeons, and dermatologists received average annual payments of $0.36 million, $6.3 million, and $6.6 million respectively (P <.001). An average of 330 otolaryngologists, 2,128 plastic surgeons, and 5,980 dermatologists were paid annually (P <.001). Accredited speaking arrangements, consulting fees, and royalty/licensing fees comprised the majority of dollars paid to physicians. Conclusions: Average physician payment by DF companies exceeds $12 million annually, with otolaryngologists receiving significantly less compared to plastic surgeons and dermatologists.

Objectives: To analyze characteristics, treatment outcomes, and prognostic factors of sarcomatoid squamous cell carcinoma of the head and neck. Study Design: Retrospective chart review. Setting: Tertiary care center. Subjects and Methods: Fifty-five patients were treated for sarcomatoid squamous cell carcinoma of the head and neck between 1996 and 2018. Data collection included clinical history, tumor characteristics, pathology, treatment modality, and outcomes. Mean follow up was 17.1 months. Cox univariate analysis was used to evaluate for associations with locoregional recurrence, distant metastasis, and overall survival. Results: Most patients were white males with a smoking history and median age 66 years (range 41-92) at diagnosis. Twenty-two percent had prior head and neck radiation. Tumor site was most frequently oral cavity (41.8%), followed by larynx (29.1%), and oropharynx (16.4%). Half presented with early T stage disease (15.5% T0, 12.7% T1, 30.9% T2) and the remainder with late stage disease (16.4% T3, 34.5% T4). Locoregional recurrence rate was 60.0%, metastatic recurrence was rate 21.8%, with median time to recurrence of 4 months and mean overall survival of 20 months. Presence of lymphovascular space invasion was statistically associated with locoregional recurrence (P =.018, HR 3.55 [95% CI 1.24, 10.14]) and poorer overall survival (P =.015, HR 2.92 [95% CI 1.23, 4.80]). Treatment with multimodality therapy was associated with decreased locoregional recurrence (P =.039, HR 0.39 [95% CI 0.16, 0.95]) but did not impact overall survival. Conclusion: Sarcomatoid squamous cell carcinoma remains a rare and aggressive disease variant with high recurrence rates and high mortality. High risk features such as lymphovascular space may indicate the need for more aggressive therapy. [ABSTRACT FROM AUTHOR]

Derakhshan, Adeeb, Greene, Jacqueline J., Gadkaree, Shekhar K., Chen, Jenny X., Jowett, Nate, and Hadlock, Tessa A.
- Abstract
Objective: Microvascular decompression (MVD) may be employed in the management of hemifacial spasm (HFS), wherein a pledget of polytetrafluoroethylene (i.e., Teflon, Chemours, Wilmington DE) is sometimes introduced to separate an offending vessel from the cisternal segment of facial nerve. Rarely, Teflon may cause a granulomatous reaction resulting in nerve palsy. We here present the first case series of facial palsy thought to be secondary to Teflon granuloma following MVD for HFS.Methods: A data repository of 1,312 patients with facial palsy was reviewed to identify individuals who had previously undergone MVD for HFS. Data collected include age at time of MVD, age at onset of facial weakness and at presentation, House-Brackmann scores, clinician-graded facial function using the Electronic Facial Paralysis Assessment scale, imaging findings, and therapeutic interventions and outcomes.Results: Six patients meeting criteria were identified. Average time between MVD with Teflon placement and onset of facial weakness was 16.1 (±4.9) years (range 9.3-23.3 years). Initial House-Brackmann scores were as follows: four patients with V/VI and one each with III/VI and IV/VI. Interventions included eyelid weight placement (n = 3), chemodenervation (n = 2), static suspension with tensor fascia latae (n = 2), dynamic reanimation with cranial nerves V to VII transfer (n = 1), and temporalis muscle transfer (n = 1).Conclusion: Teflon granuloma should be considered in the differential diagnosis for patients presenting with new onset facial weakness with a previous history of MVD for HFS. It remains unknown whether early granuloma extirpation is effective. Prompt diagnosis allows consideration of time-sensitive nerve transfer procedures to reanimate facial function.Level Of Evidence: 4 Laryngoscope, 130:1422-1427, 2020.

- Abstract
Objective(s): To characterize procedural trends in facial plastic and reconstructive surgery procedures in relation to the United States economy.Methods: Retrospective cohort study examining annual procedure rates were determined from the American Society of Plastic Surgeons (ASPS) National Clearinghouse of Plastic Surgery Procedural Statistics from January 1 2007 to December 30, 2017. Procedures were compared to economic activity of the United States as measured by gross domestic product (GDP) were compared using Kolmogorov-Smirnov goodness of fit testing and piecewise multivariate regression modeling.Results: Annual trends in procedural rates showed an overall decrease in the rates of rhinoplasty (284,960 to 218,924), blepharoplasty (240,660 to 209,571), and otoplasty (28,571 to 23,433) from 2007 to 2017. Total cosmetic surgery remained fairly stable, while minimally invasive cosmetic surgery increased in frequency over the study period. On piecewise regression analysis, rhinoplasty (P = .02), rhytidectomy (P = .007), invasive cosmetic surgery (P < .001) were significantly associated with GDP, whereas otoplasty (P = .98) and reconstructive surgery (P = .11) were not associated with GDP.Conclusion: Cosmetic plastic surgery procedures show a greater correlation to GDP than reconstructive procedures. Trends in plastic surgery cases over the last decade show a decreasing number of rhinoplasty, otoplasty, and blepharoplasty, with stabilization in the last few years. An increasing number of reconstructive cases are found.Level Of Evidence: 4 Laryngoscope, 130:632-636, 2020. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Objectives: The Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) established a standardized, tiered reporting system for salivary gland fine-needle aspiration (FNA) that has gained international acceptance among cytologists. Our goal was to review the key features of the MSRSGC to familiarize the surgical community with this system and its application to the FNA evaluation of salivary gland masses.Methods: A comprehensive review of the MSRSGC and its application in clinical practice.Results: The MSRSGC consists of six major diagnostic categories: 1) nondiagnostic, 2) non-neoplastic, 3) atypia of undetermined significance, 4) neoplasm (benign or salivary gland neoplasm of uncertain malignant potential), 5) suspicious for malignancy, and 6) malignant. Each diagnostic category is associated with an implied risk of malignancy with implications for clinical management.Conclusions: The MSRSGC is similar to the system used for reporting thyroid FNA, which is familiar to most otolaryngologists and head and neck surgeons. As this reporting system continues to gain popularity among pathologists, widespread understanding by surgeons will be important to standardize communication and classification of salivary gland cytopathology to improve clinical care.

- Abstract
Background: Facial filler is emerging as a nonsurgical alternative for addressing static asymmetry in facial paralysis (FP). Objectives: To elucidate the patient experience for facial filler and to facilitate preprocedure counseling and education. Materials and Methods: Patients receiving hyaluronic acid filler for FP at a tertiary academic medical center were prospectively recruited. Primary outcomes included patient-reported pain, facial symmetry (on a visual analog scale), and the results of quality-of-life surveys (FACE-Q satisfaction with facial appearance [SFA], FACE-Q psychosocial distress [PSD], Patient Health Questionnaire-9 [PHQ-9], and Euro Quality of Life 5-Dimension [EQ5D]) preprocedure and at 1 and 14 days postprocedure. Results: Twenty patients (90% women, average age 55 ± 11) completed the study. Sites of filler included the cheek, lower lip, nasolabial fold, chin, and temple regions. Patients reported minimal pain at postprocedure days (PPDs) 1 and 14. Patient-perceived symmetry scores improved significantly ( p < 0.0001), as did FACE-Q SFA and FACE-Q PSD scores ( p < 0.0001, <0.0001) when comparing preprocedure with PPD 14. Depression, assessed by PHQ-9, and the anxiety/depression domain of EQ5D, decreased after treatment ( p = 0.016, 0.014) but no change was observed in the other domains of EQ5D. Conclusion: Facial filler for FP can be performed with minimal morbidity (pain, impact on daily routine, and complications) and leads to improvements across multiple psychosocial domains.

- Abstract
Background: Facial filler is an effective nonsurgical treatment option for improving facial symmetry in patients with facial paralysis (FP). Objective: To compare the effects of filler among patients with FP that is self-perceived as major or minor asymmetry, by measuring psychosocial distress. Methods: In this prospective cohort study of patients with FP undergoing filler at a tertiary academic center, patients were classified as having minor or major self-perceived asymmetry using a visual analog scale (VAS). FACE-Q Appearance-Related Psychosocial Distress was administered before and after filler. Descriptive statistics and a random-effects generalized linear model assessed the relationship between perceived facial asymmetry and change in psychosocial distress. Results: A total of 28 patients participated. Twenty-five (89%) patients were female with median age of 54 (interquartile range [IQR]: 49-66). Median VAS score was 2 (IQR: 1-3.5, 0 = completely asymmetric, 10 = no asymmetry). Psychosocial distress improved in all patients after filler. In multivariable modeling, patients with major asymmetry experienced 2.45 (confidence interval: 0.46-4.44, p = 0.016) points more improvement in psychosocial distress than patients with minor asymmetry. Age, gender, and FP duration were not associated with change in psychosocial distress. Conclusion: Facial filler treatment was seen to improve psychosocial distress in patients with FP, especially by those with more self-perceived deficit.

- Abstract
Objective: To determine demographic and socioeconomic variables associated with whether surgery is performed for patients with facial paralysis (FP). Background: Management of FP may include elective surgery dependent on patient goals of care and physician experience. Methods: The 2016 State Inpatient Database and State Ambulatory Surgery Services Database for six states were queried to identify patients with FP. These patients were then stratified based on receiving surgery for FP. Demographic and socioeconomic information was collected. Multivariable logistic regression modeling was used to identify predictors of undergoing FP surgery, as well as the hospital setting in which surgery was performed. Results: Of 20,218 patients with FP, 515 underwent surgery. Black patients were significantly less likely to undergo surgery ( p < 0.001), as were patients with Medicaid or self-pay insurance ( p < 0.001). Those living in rural areas were also less likely to receive surgery ( p = 0.001). Individuals receiving surgery in the inpatient setting were more likely to have private insurance, whereas those in the ambulatory setting were more likely to have Medicare ( p < 0.001). Conclusion: Several variables are correlated with whether FP is managed surgically, including insurance status, race, and type of residential area.

- Abstract
Background: Gender-affirming surgery may be pursued by individuals experiencing gender dysphoria. Although genital and chest procedures are classified as medically necessary, facial feminization surgeries (FFSs) are often considered cosmetic. Insurance companies may limit coverage of these procedures, especially in states less supportive of transgender individuals. Objectives: To determine insurance coverage and ease of finding policy information for FFSs, and to analyze differences based on state advocacy. Methods: Insurance policies for the top three commercial health plans per state were reviewed. Coverage status was determined by web-based search and telephone interviews. Ease of gathering policy information was assessed using a post-task questionnaire graded on a 7-point Likert scale, with higher numbers (e.g., 7) representing relative ease. State advocacy was determined by the number of state laws and policies affecting the transgender community. Results: Of the 150 insurance policies, only 27 (18%) held favorable policies for FFS. Most favorable companies covered chondrolaryngoplasty, with 78% ( n = 21) offering preauthorization. Mean ease of use was rated 6, with 12 companies requiring a telephone interview. Insurance policies in states with laws driving transgender equity covered more FFS procedures ( p = 0.043), whereas those in restrictive states offered less overall coverage ( p = 0.023). Conclusions: FFS is rarely covered by commercial insurance companies, especially in states with less legal support for transgender individuals. Policy information remains difficult to obtain, with variable coverage by employer and no standardized medical necessity criteria. Limited coverage, lack of easily accessible information, and absence of universal criteria may act as barriers to FFS.

- Abstract
Background: COVID-19 poses a potentially significant infectious risk during procedures of the head and neck due to high viral loads in the nasal cavity and nasopharynx. Facial plastic surgery has significant exposure to these areas during craniomaxillofacial trauma procedures and rhinoplasty. Methods: Airborne particulate generation in the 1-10 μm range was quantified with an optical particle sizer in real time during cadaveric-simulated rhinoplasty and facial trauma conditions. Procedures tested included mandibular plate screw drilling, calvarial drilling, nasal bone osteotomy, nasal dorsal rasping, and piezoelectric saw use. Particulate generation was measured both adjacent to the surgical site and at surgeon mouth level (SML). Results: Mandibular plate screw drilling without irrigation generated significant particulate both adjacent to the surgical site and at SML ( p < 0.01). Irrigation mitigated particulate generation at SML to nonsignificant levels. Calvarial drilling additionally produced substantial particulate above baseline adjacent to the surgical site ( p < 0.01). Standard nasal osteotomies and dorsal rasping did not generate detectable airborne particulate, whereas piezoelectric saw use was associated with significant particulate generation both adjacent to the surgical site ( p < 0.001) and at SML ( p < 0.01). At SML, smaller particulate represented a significantly higher proportion of total particulate detected. Conclusions: The majority of craniomaxillofacial trauma procedures involve particle generation that may be limited in spread by the use of local irrigation. Most bony work involved in rhinoplasty can be safely performed without a high degree of particle formation. The use of piezoelectric instruments in rhinoplasty should be avoided when concerned for particulate generation.

- Abstract
Background: In the care of the facial paralysis (FP) patient, outcomes have historically focused on facial function rather than the psychosocial burden of the disease state. Yet, FP patients often describe the impact of their disease on domains of psychosocial health. These patient concerns have motivated clinicians to formally recognize and treat nonfunctional sequelae of the disease. Dermal filler therapy (DFT) is a minimally invasive reversible procedure that can be used to treat facial asymmetry and improve psychosocial well-being in FP patients. However, there are no data describing outcomes of DFT in FP-related facial asymmetry. Therefore, we sought to formally characterize FP patients' facial symmetry and psychosocial well-being before and after DFT. Methods: FP patients presenting for DFT at a tertiary academic medical center were prospectively interviewed. Patients completed the validated FACE-Q for Appearance-Related Psychosocial Distress instrument. Self-reported facial symmetry scores were recorded. Patients were evaluated before and 2 weeks after DFT. Statistical analysis was performed on R software using paired sample t -tests. Results: Twenty FP patients completed DFT treatment and two surveys. The cohort was predominantly female ( n = 19, 95%) with an average age of 54 years. After a single treatment of DFT averaging 2.3 mL, patients had significant improvement in facial symmetry and psychosocial well-being. Patients felt particular improvement in self-confidence and emotional expression ( p < 0.0001 for all stated comparisons). Conclusion: FP of varying etiologies is associated with significant functional, psychosocial, and quality-of-life impairments. This is the first prospective study to demonstrate statistically significant improvements in facial symmetry and psychosocial well-being after a single office-based treatment of dermal filler. In addition, our study's emphasis on psychosocial health instruments reflects an increased awareness of this important domain in the care of the FP patient.

- Abstract
Background: Understanding the multidimensional postoperative patient experience after rhinoplasty is critical for preoperative counseling and postoperative management. Methods: A prospective clinical study was conducted from June to December 2019 for 60 patients undergoing cosmetic and/or functional rhinoplasty by two facial plastic surgeons. All patients were administered the brief pain inventory, a clinically validated pain instrument, including multiple quality of life (QOL) domains, survey at postoperative days (PODs) 1, 2, 3, and 8. Nasal Obstruction Symptom Evaluation (NOSE) scores were used to predict patients having greatest QOL disturbance. Primary outcomes were postoperative QOL domains, pain scores, and oxycodone usage. Statistical analysis was performed using STATA 14.0 (STATA Corp., College Station, TX). Preoperative NOSE and postoperative Euro Quality of Life 5-Dimension scores were also recorded. Results: Patients showed greatest disruption to QOL in the first 3 PODs and essentially returned to normal levels by POD8, which mirrored trends in pain and opioid usage. All tested QOL domains (general activity, sleep, work, mood, enjoyment, and relationships) were strongly correlated with overall pain. NOSE scores were not significantly associated with pain or QOL impairment. Conclusions: This is the first study to prospectively evaluate the rhinoplasty patient's postoperative experience using a pain instrument, including multiple QOL domains. Utilizing a validated clinical instrument allows for standardized comparison of postrhinoplasty pain and QOL disruption with other surgical procedures and disease processes. These data may help guide preoperative counseling and set accurate patient expectations for the postoperative period.

- Abstract
Purpose: Human papillomavirus-negative (HPV
- ) head and neck squamous cell carcinomas (HNSCC) harbor frequent genomic amplification of Fas-associated death domain, with or without concurrent amplification of Baculovirus inhibitor of apoptosis repeat containing (BIRC2/3) genes encoding cellular inhibitor of apoptosis proteins 1/2 (cIAP1/2). Antagonists targeting cIAP1 have been reported to enhance sensitivity of HPV- , but not HPV+ tumors, to TNF family death ligands (TNF and TRAIL) and radiation. Experimental Design: We tested a novel dual cIAP/XIAP antagonist ASTX660 in HPV+ and HPV- cell lines in combination with death ligands TNFα and TRAIL, and in preclinical xenograft models with radiation, an inducer of death ligands. The dependence of activity on TNF was examined by antibody depletion., Results: ASTX660 sensitized subsets of HPV- and HPV+ HNSCC cell lines to TNFα and TRAIL. These antitumor effects of ASTX660 are the result of both apoptosis and/or necroptosis among HPV- cells, and primarily by apoptosis (caspase 3 and caspase 8 cleavage) in HPV+ cells. ASTX660 enhanced restoration of protein expression and inhibitory activity of proapoptotic tumor suppressor TP53 in HPV+ HNSCC. Furthermore, ASTX660 combined with radiotherapy, an inducer of death ligands, significantly delayed growth of both HPV- and HPV+ human tumor xenografts, an effect attenuated by anti-TNFα pretreatment blockade., Conclusions: IAP1/XIAP antagonist, ASTX660, sensitizes HPV+ HNSCC to TNFα via a mechanism involving restoration of TP53. These findings serve to motivate further studies of dual cIAP/XIAP antagonists and future clinical trials combining these antagonists with radiotherapy to treat both HPV+ and HPV- HNSCC., (©2019 American Association for Cancer Research.)- Published

- Abstract
Importance: By measuring health utility values (HUVs) for patients with nasal obstruction after septorhinoplasty, the association of nasal congestion with overall health can be measured and the functional outcomes of septorhinoplasty can be determined., Objective: To use the EuroQol 5-Dimension (EQ-5D) questionnaire to evaluate nasal obstruction outcomes after septorhinoplasty and to determine HUVs., Design, Setting, and Participants: This prospective cohort study included patients who underwent septorhinoplasty for nasal obstruction at a single institution by a single surgeon from January 1, 2013, through December 31, 2017. Participants completed the EQ-5D questionnaire immediately before surgery and postoperatively at 2, 4, 6, and 12 months. The EQ-5D scores were converted to HUVs using population-based data for individuals with chronic diseases. Data were analyzed from May 1 through December 31, 2018., Exposure: Functional septorhinoplasty., Main Outcomes and Measures: Preoperative and postoperative EQ-5D scores were compared to evaluate improvement in overall health after septorhinoplasty., Results: A total of 463 patients (53.8% women; mean [SD] age, 36.8 [15.7] years) who underwent septorhinoplasty and completed EQ-5D surveys at baseline and postoperatively were included in the study population. Overall mean (SD) preoperative HUV was 0.872 (0.01), compared with 1.00 for those with a perfect state of health. On univariate analysis, female sex (mean [SD] HUV, 0.853 [0.01]; P = .004), previous nasal surgery (mean [SD] HUV, 0.85 [0.16]; P = .02), previous septoplasty (mean [SD] HUV, 0.88 [0.15]; P = .02), and previous sinus surgery (mean [SD] HUV, 0.79 [0.20]; P = .009) were associated with significantly lower baseline HUVs. On multivariate regression including these variables, only previous septoplasty was significantly associated with a positive change in mean (SD) HUV (0.88 [0.15] vs 0.85 [0.16]; P = .02). Mean (SD) HUV was significantly improved at 2 months postoperatively to 0.91 (0.14; P = .001) and remained significantly improved from baseline at 12 months, at 0.93 (0.13; P < .001)., Conclusions and Relevance: Nasal obstruction is associated with significant detriment to overall health, in line with other chronic conditions affecting the US population. Functional septorhinoplasty appears to substantially improve overall health, as measured by HUV, in an immediate and sustained fashion., Level of Evidence: 3.

- Abstract
Importance: Using health utility values (HUVs) as an outcome measure for surgical procedures, including rhinoplasty, allows for a standardized measurement of the qualitative and financial benefit of that procedure on overall health., Objective: To use Euroqol 5-Dimension (EQ-5D)-derived HUVs to evaluate nasal obstruction outcomes following surgery between primary rhinoplasty (PSRP) and rhinoplasty with previous nasal surgery (RNS) in a prospective cohort study., Design, Setting, and Participants: A single-institution prospective cohort study between 2013 and 2017 was carried out including 185 patients who underwent RNS before functional rhinoplasty and 278 patients who underwent PSRP for nasal obstruction. The analysis was carried out between December 2018 and February 2019., Main Outcomes and Measures: Patients in the RNS cohort and PSRP cohort who completed the EQ-5D questionnaire immediately prior to surgery and postoperatively at 2, 4, 6, and 12 months were included in the study. The EQ-5D scores were converted to HUV scores and compared to evaluate for improvement in health status following surgery., Results: Of the 185 patients in the RNS cohort, 97 (52%) were women and the mean (SD) age was 42.6 (13.4) years. Of the 278 in the PSRP cohort, 156 (55%) were women and the mean (SD) age was 36.0 (15.8) years. Both cohorts experienced significant improvement in HUV postoperatively. The mean (SD) HUV values were decreased in the RNS cohort versus the PSRP cohort both preoperatively (0.85 [0.16] versus 0.89 [0.14]) and postoperatively at 1 year (0.92 [0.14] versus 0.94 [0.11]); however, the difference in HUV was not statistically significant after 6 months postoperatively. Patients in the RNS cohort were typically older (76 [41%] older than 40 years vs 84 [31%], P = .02) and more likely to have sleep apnea (31 [19%] vs 24 [10%], P = .01) than in the PSRP cohort. On multivariable analysis, the use of spreader grafts and alar rim grafts in the PSRP cohort was significantly associated with improved HUV at 12 months. (r = -0.06; 95% CI, -0.11 to -0.01, P = .03)., Conclusions and Relevance: Patients with a history of prior nasal surgery may represent a unique cohort when assessing health utility outcomes. Euroqol 5-dimension questionnaire-derived HUVs are a valid predictor of outcomes in all patients who undergo septorhinoplasty. Although outcomes were significantly improved for both cohorts, previous surgical history should be considered when performing cost utility analysis on the benefits of functional rhinoplasty., Level of Evidence: 3.

- Abstract
Objectives: Facelifts are among the most common facial plastic procedures performed. Given the existence of a variety of surgical approaches and the proximity of key anatomical structures, the development of proper surgical skills and knowledge is necessary to ensure positive outcomes. Many surgical learners utilize YouTube videos as supplemental tools in their education. Our aim was to gauge the quality and quantity of available YouTube videos describing the surgical approach to rhytidectomy., Methods: The YouTube video platform was searched using predefined keywords. Videos meeting inclusion criteria were reviewed and scored by 3 practicing facial plastic and reconstructive surgeons. Thirteen different intraoperative, pre/postoperative, and video quality characteristics were scored on a binary scale by each grader. Descriptive statistics were obtained and interrater reliability was assessed using Kappa's coefficient., Results: Thirteen videos met criteria for analysis. A high degree of interrater reliability was confirmed using Kappa's coefficient, with κ values = 0.73, 0.75, and 0.59 for each combination of scorers. In general, YouTube videos were found to be deficient in discussing key criteria of rhytidectomy, particularly with regards to pre/postoperative points such as indications, patient selection, and possible complications. Intraoperative benchmarks were also lacking, with 8/13 videos not discussing the facial nerve and 8/13 failing to demonstrate an appropriate facelift incision., Conclusions: YouTube instructional videos depicting rhytidectomy lack discussion of key tenets of successful facelift surgery. Until improvement in the educational quality of such material occurs, surgical trainees should implement discretion when choosing YouTube videos to complement their learning., Level of Evidence: Not Applicable., (Copyright © 2019 Elsevier Inc.

- Abstract
Study Design: Retrospective multicenter case series study., Objective: Because cervical dural tears are rare, most surgeons have limited experience with this complication. A multicenter study was performed to better understand the presentation, treatment, and outcomes following cervical dural tears., Methods: Multiple surgeons from 23 institutions retrospectively identified 21 rare complications that occurred between 2005 and 2011, including unintentional cervical dural tears. Demographic data and surgical history were obtained. Clinical outcomes following surgery were assessed, and any reoperations were recorded. Neck Disability Index (NDI), modified Japanese Orthopaedic Association (mJOA), Nurick classification (NuC), and Short-Form 36 (SF36) scores were recorded at baseline and final follow-up at certain centers. All data were collected, collated, and analyzed by a private research organization., Results: There were 109 cases of cervical dural tears among 18 463 surgeries performed. In 101 cases (93%) there was no clinical sequelae following successful dural tear repair. There were statistical improvements ( P < .05) in mJOA and NuC scores, but not NDI or SF36 scores. No specific baseline or operative factors were found to be associated with the occurrence of dural tears. In most cases, no further postoperative treatments of the dural tear were required, while there were 13 patients (12%) that required subsequent treatment of cerebrospinal fluid drainage. Analysis of those requiring further treatments did not identify an optimum treatment strategy for cervical dural tears., Conclusions: In this multicenter study, we report our findings on the largest reported series (n = 109) of cervical dural tears. In a vast majority of cases, no subsequent interventions were required and no clinical sequelae were observed., Competing Interests: Declaration of Conflicting Interests: The author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: Kevin R.

- Abstract
Study Design: A multicenter, retrospective review of C5 palsy after cervical spine surgery., Objective: Postoperative C5 palsy is a known complication of cervical decompressive spinal surgery. The goal of this study was to review the incidence, patient characteristics, and outcome of C5 palsy in patients undergoing cervical spine surgery., Methods: We conducted a multicenter, retrospective review of 13 946 patients across 21 centers who received cervical spine surgery (levels C2 to C7) between January 1, 2005, and December 31, 2011, inclusive. P values were calculated using 2-sample t test for continuous variables and χ
2 tests or Fisher exact tests for categorical variables., Results: Of the 13 946 cases reviewed, 59 patients experienced a postoperative C5 palsy. The incidence rate across the 21 sites ranged from 0% to 2.5%. At most recent follow-up, 32 patients reported complete resolution of symptoms (54.2%), 15 had symptoms resolve with residual effects (25.4%), 10 patients did not recover (17.0%), and 2 were lost to follow-up (3.4%)., Conclusion: C5 palsy occurred in all surgical approaches and across a variety of diagnoses. The majority of patients had full recovery or recovery with residual effects.

- Abstract
The Cancer Genome Atlas (TCGA) has unveiled genomic deregulation of various components of the extrinsic and intrinsic apoptotic pathways in different types of cancers. Such alterations are particularly common in head and neck squamous cell carcinomas (HNSCC), which frequently display amplification and overexpression of the Fas-associated via death domain (FADD) and inhibitor of apoptosis proteins (IAP) that complex with members of the TNF receptor family. Second mitochondria-derived activator of caspases (SMAC) mimetics, modeled after the endogenous IAP antagonist SMAC, and IAP inhibitors represent important classes of novel small molecules currently in phase I/II clinical trials. Here we review the physiologic roles of IAPs, FADD, and other components involved in cell death, cell survival, and NF-κB signaling pathways in cancers, including HNSCC. We summarize the results of targeting IAPs in preclinical models of HNSCC using SMAC mimetics. Synergistic activity of SMAC mimetics together with death agonists TNFα or TRAIL occurred in vitro , whereas their antitumor effects were augmented when combined with radiation and chemotherapeutic agents that induce TNFα in vivo In addition, clinical trials testing SMAC mimetics as single agents or together with chemo- or radiation therapies in patients with HNSCC and solid tumors are summarized. As we achieve a deeper understanding of the genomic alterations and molecular mechanisms underlying deregulated death and survival pathways in different cancers, the role of SMAC mimetics and IAP inhibitors in cancer treatment will be elucidated. Such developments could enhance precision therapeutics and improve outcomes for cancer patients. Clin Cancer Res; 23(6); 1379-87. ©2016 AACR ., (©2016 American Association for Cancer Research.)

- Abstract
Comparison of tumors from The Cancer Genome Atlas (TCGA) reveals that head and neck squamous cell carcinomas (HNSCC) harbor the most frequent genomic amplifications of Fas-associated death domain (FADD), with or without Baculovirus inhibitor of apoptosis repeat containing BIRC2 (cIAP1), affecting about 30% of patients in association with worse prognosis. Here, we identified HNSCC cell lines harboring FADD/BIRC2 amplifications and overexpression by exome sequencing, RT-PCR, and Western blotting. In vitro, FADD or BIRC2 siRNA knockdown inhibited HNSCC displaying amplification and increased expression of these genes, supporting their functional importance in promoting proliferation. Birinapant, a novel SMAC mimetic, sensitized multiple HNSCC lines to cell death by agonists TNFα or TRAIL and inhibited cIAP1>XIAP>IAP2. Combination of birinapant and TNFα induced sub-G0 DNA fragmentation in sensitive lines and birinapant alone also induced significant G2-M cell-cycle arrest and cell death in UM-SCC-46 cells. Gene transfer and expression of FADD sensitized resistant UM-SCC-38 cells lacking FADD amplification to birinapant and TNFα, supporting a role for FADD in sensitization to IAP inhibitor and death ligands. HNSCC varied in mechanisms of cell death, as indicated by reversal by inhibitors or protein markers of caspase-dependent apoptosis and/or RIPK1/MLKL-mediated necroptosis. In vivo, birinapant inhibited tumor growth and enhanced radiation-induced TNFα, tumor responses, and host survival in UM-SCC-46 and -11B xenograft models displaying amplification and overexpression of FADD+/- BIRC2 These findings suggest that combination of SMAC mimetics such as birinapant plus radiation may be particularly active in HNSCC, which harbor frequent FADD/BIRC2 genomic alterations.

- Abstract
Study Design: A retrospective 1-year cost-utility analysis., Objective: To determine the cost-effectiveness of using recombinant human bone morphogenic protein (rhBMP-2) in addition to autograft for 1- and 2-level lumbar fusions., Summary of Background Data: rhBMP-2 has been studied extensively to identify its benefits, risks, patient outcomes, and costs relative to autograft [local bone or iliac crest bone graft (ICBG)]. This study seeks to analyze the cost-effectiveness of adding rhBMP-2 to autograft versus without rhBMP-2 in lumbar fusions., Methods: Thirty-three patients receiving rhBMP-2 in addition to either local bone autograft or ICBG (rhBMP-2 cohort) and 42 patients receiving only local bone autograft or ICBG (control cohort) for 1- or 2-level dorsal lumbar fusion were analyzed. This included posterolateral fusion, posterior lumbar interbody fusion, and transforaminal lumbar interbody fusion. One-year postoperative health outcomes were assessed based on Visual Analogue Scale, Pain Disability Questionnaire, Patient Health Questionnaire, and EuroQol-5 Dimensions questionnaires. Direct medical costs were estimated using Medicare national payment amounts and indirect costs were based on patient missed work days and patient income. Postoperative 1-year cost-utility ratios and the incremental cost-effectiveness ratio (ICER) were calculated to assess for cost-effectiveness using a threshold of $100,000/QALY gained., Results: The 1-year cost-utility ratio (total cost/ΔQALY) for the control cohort was significantly lower ($143,251/QALY gained) than that of the rhBMP-2 cohort ($272,414/QALY gained) (P<0.01). At 1-year follow-up, the control group dominated the ICER compared with the rhBMP-2 group., Conclusions: Statistically significant and clinically relevant improvements (through minimum clinically important differences) were seen for both cohorts. In the ICER analysis, the control cohort dominated the rhBMP-2 group. Assuming durable per year gains in QALY, by 2 years fusion with autograft but without rhBMP-2 would be considered cost-effective ($71,625/QALY gained), whereas fusion with both autograft and rhBMP-2 would not be cost-effective ($136,207/QALY gained).

- Abstract
Circulating tumor cells have emerged as prognostic biomarkers in the treatment of metastatic cancers of epithelial origins viz., breast, colorectal and prostate. These tumors express Epithelial Cell Adhesion Molecule (EpCAM) on their cell surface which is used as an antigen for immunoaffinity capture. However, EpCAM capture technologies are of limited utility for non-epithelial cancers such as melanoma. We report a method to enrich Circulating Melanoma Cells (CMCs) that does not presuppose malignant cell characteristics. CMCs were enriched by centrifugation of blood samples from healthy (N = 10) and patient (N = 11) donors, followed by RBC lysis and immunomagnetic depletion of CD45-positive leukocytes in a specialized magnetic separator. CMCs were identified by immunocytochemistry using Melan-A or S100B as melanoma markers and enumerated using automated microscopy image analyses. Separation was optimized for maximum sensitivity and recovery of CMCs. Our results indicate large number of CMCs in Stage IV melanoma patients. Analysis of survival suggested a trend toward decreased survival with increased number of CMCs. Moreover, melanoma-associated miRs were found to be higher in CMC-enriched fractions in two patients when compared with the unseparated samples, validating this method as applicable for molecular analyses. Negative selection is a promising approach for isolation of CMCs and other EpCAM -negative CTCs, and is amenable to molecular analysis of CMCs. Further studies are required to validate its efficacy at capturing specific circulating cells for genomic analysis, and xenograft studies.

- Abstract
The reaction of the methylidyne radical (CH) with acetone ((CH(3))(2)C[double bond, length as m-dash]O) is studied at room temperature and at a pressure of 4 Torr (533.3 Pa) using a multiplexed photoionization mass spectrometer coupled to the tunable vacuum ultraviolet synchrotron radiation of the Advanced Light Source at Lawrence Berkeley National Laboratory. The CH radicals are generated by 248 nm multiphoton photolysis of bromoform and react with acetone in an excess of helium and nitrogen gas flow. The main observed reaction exit channel is elimination of a hydrogen atom to form C(4)H(6)O isomers. Analysis of photoionization spectra identifies dimethylketene and methacrolein as the only H-elimination products. The best fit to the data gives branching ratios of 0.68 ± 0.14 for methacrolein and 0.32 ± 0.07 for dimethylketene. A methylketene spectrum measured here is used to reanalyze the photoionization spectrum obtained at m/z = 56 for the CH + acetaldehyde reaction, (Goulay et al., J. Phys. Chem. A, 2012, 116, 6091) yielding new H-loss branching ratios of 0.61 ± 0.12 for acrolein and 0.39 ± 0.08 for methylketene. The contribution from methyleneoxirane to the reaction product distribution is revised to be negligible. Coupled with additional product detection for the CD + acetone reaction, these observations pave the way for development of general set of reaction mechanisms for the addition of CH to compounds containing an acetyl subgroup.
