Ergonomics in facial plastic and reconstructive surgery.

PURPOSE OF REVIEW: Understanding effective ergonomic interventions is crucial for enhancing occupational health and career longevity. There is a paucity of clear ergonomics guidelines in facial plastic and reconstructive surgery (FPRS), placing practitioners at high risk of work-related musculoskeletal disorders (WMSDs) and their consequences. RECENT FINDINGS: There is mounting evidence that FPRS specialists are at increased risk of WMSDs as compared with the public and other surgical specialties. Numerous studies have demonstrated that implementation of ergonomics principles in surgery decreases WMSDs. Furthermore, WMSDs are reported as early as the first year of surgical residency, marking the importance of early intervention. SUMMARY: Fatigue and physical injuries among surgeons occur more often than expected, particularly during complex, extended procedures that necessitate maintaining a constant posture. FPRS procedure often place surgeons into procrustean positions. Thus, integrating ergonomic practices into the practice of FPRS is essential for reducing WMSDs.

Wire Osteosynthesis in the Treatment of Mandible Fractures in Low Resource Settings: A Force Study.

Study Design: Cadaveric investigation. Objective: Rigid internal fixation (RIF) using plates and screws is often not feasible in low and middle-income countries due to limited resources. Interosseous wiring to achieve semi-rigid fixation is often used, but lacks biomechanical force data. Herein we aim to quantitatively compare interosseous wiring to RIF. Methods: Cadaveric mandibles were fractured at the parasymphysis and angle. Fixation was achieved using interosseous wiring in both single wire loop and figure-of-eight formations, as well as plate and screw fixation (n = 5 for each fixation type at each fracture site). A force gauge was used to measure the number of Newtons (N) required to achieve diastasis and complete failure at the fixation site. Results: For angle fractures, the mean force required for initial diastasis was 4.1, 5.9, and 10.9 N for single wire, figure-of-eight wiring, and plating respectively (P < .001). Complete failure was achieved with 152.9, 168.9, and 237.6 N of force for the three methods, respectively (P < .001). Complete failure was achieved for parasymphyseal fractures with 197.7, 263.0, and 262.8 N of force for single wire, figure-of-eight wiring, and plating respectively (P = .002). Forces to achieve initial diastasis for parasymphyseal fractures were not statistically significant among the three fixation methods (P = .29). Conclusions: Figure-of-eight interosseous wiring resists comparable forces across mandibular fractures compared to the gold standard of plating. In resource-limited settings when plates and screws are not available, this technique can be considered to achieve semi-rigid fixation of mandibular fractures.

Quantifying Facial Distortion in Modern Digital Photography.

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.

Facial Filler in Facial Paralysis: A Prospective Case Study and Multidimensional Assessment.

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.

Effect of Filler Therapy on Psychosocial Distress in Facial Paralysis: Patients with Major Asymmetry Derive Greater Benefit.

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.

Health Utility Measures Among Patients with Androgenetic Alopecia After Hair Transplant.

BACKGROUND: Hair loss causes significant psychosocial distress to patients. Health utility measurements offer an objective, quantitative assessment of health-related quality of life (QOL). METHODS: We performed a prospective cohort study on patients with hair loss between January 1, 2018 and December 31, 2020. Patient metrics were compared with layperson perception of alopecia, prospectively collected between August 1 and December 31, 2017. Health utility measures were quantified using the visual analog scale (VAS), standard gamble (SG), and time trade-off (TTO) in quality-adjusted life-years (QALYs) and relative to the minimal clinically important difference (MCID). Bonferroni correction to the significance threshold was performed. RESULTS: Thirty-one patients with alopecia were compared with 237 laypeople. Patient metrics for female hair loss were all significantly lower than laypeople measures (VAS QALYs 0.65 ± 0.21 vs. 0.83 ± 0.18, p = 0.0001). Mean SG QALYs were lower for patients in the male alopecia state (0.86 ± 0.23 vs. 0.96 ± 0.12, p = 0.0278). Post-hair transplant improvement in TTO was significantly greater for patients (+ 0.08 ± 0.12 vs. + 0.02 ± 0.09, p = 0.0070) and significantly more often exceeded the MCID (45.2% vs. 16.9%, p = 0.0006). CONCLUSIONS: Alopecia negatively impacts QOL, and the true patient experience is more taxing than what is perceived by laypeople. Hair transplantation improves QOL more for male patients than common perception. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.

Surgical Management of Facial Paralysis: Demographic and Socioeconomic Associations.

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.

Releasing the Smile: Depressor Anguli Oris Excision in the Context of Managing Nonflaccid Facial Palsy.

BACKGROUND: Nonflaccid facial palsy is a debilitating entity characterized by hypertonicity, synkinesis, and hypomobility. Patients with nonflaccid facial palsy often have smile asymmetry and restriction because of disruption of normal vector forces on the modiolus. Excision of the depressor anguli oris can lead to improved oral commissure excursion, smile angle, dental show, and symmetry. METHODS: All depressor anguli oris resection cases between January 8, 2018, and December 26, 2019, were reviewed. Patients with postoperative photographs were included in this cohort study. Preoperative and postoperative photographs were analyzed using the Emotrics software program, and changes in oral commissure excursion, smile angle, and dental show were tracked. Clinician-graded facial palsy assessments and patient-reported outcome measures were compared preoperatively and postoperatively using the Electronic Facial Paralysis Assessment and Facial Clinimetric Evaluation Scale, respectively. RESULTS: Forty-three patients were included in this study; 79 percent of patients underwent isolated depressor anguli oris resection. Depressor anguli oris resection led to a statistically significant increase in oral commissure median excursion, smile angle, and dental show [3.02 mm (p = 0.015), 1.70 degrees (p = 0.002), and 2.36 mm (p < 0.001), respectively]. Median Electronic Facial Paralysis Assessment and Facial Clinimetric Evaluation Scale instrument scores also improved [6.0 (p = 0.001) and 7.5 (p = 0.013), respectively]. Depressor anguli oris resection also led to more symmetric smiles. No correlation was seen between duration of follow-up and change in metrics. CONCLUSION: Depressor anguli oris resection is a minimal-risk procedure that frequently results in improved smile dynamics, smile symmetry, and quality of life in patients with nonflaccid facial palsy. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Otolaryngologists Trail Other Specialties in Industry Payments From Dermal Filler Companies.

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.

Death agonist antibody against TRAILR2/DR5/TNFRSF10B enhances birinapant anti-tumor activity in HPV-positive head and neck squamous cell carcinomas.

Head and neck squamous cell carcinomas (HNSCC) induced by human papillomavirus (HPV) have increased recently in the US. However, the distinct alterations of molecules involved in the death pathways and drug effects targeting inhibitor of apoptosis proteins (IAPs) have not been extensively characterized in HPV(+) HNSCC cells. In this study, we observed the distinct genomic and expression alterations of nine genes involved in cell death in 55% HNSCC tissues, which were associated with HPV status, tumor staging, and anatomic locations. Expression of four genes was statistically correlated with copy number variation. A panel of HPV(+) HNSCC lines showed abundant TRAILR2 and IAP1 protein expression, but were not sensitive to IAP inhibitor birinapant alone, while combinatory treatment with TNFα or especially TRAIL enhanced this drug sensitivity. The death agonistic TRAILR2 antibody alone showed no cell inhibitory effects, whereas its combination with birinapant and/or TRAIL protein demonstrated additive or synergistic effects. We observed predominantly late apoptosis mode of cell death after combinatorial treatments, and pan-caspase (ZVAD) and caspase-8 (ZIETD) inhibitors attenuated treatment-induced cell death. Our genomic and expression data-driven study provides a framework for identifying relevant combinatorial therapies targeting death pathways in HPV(+) HNSCC and other squamous cancer types.

The Effect of Age on Fat Distribution in the Neck Using Volumetric Computed Tomography.

BACKGROUND: Neck fat distribution plays an important role in aging, yet how fat distribution changes with age is largely unknown. This study used volumetric computed tomography in live patients to characterize neck fat volume and distribution in young and elderly women. METHODS: A retrospective analysis was conducted of head and neck computed tomographic angiographs of 20 young (aged 20 to 35 years) and 20 old (aged 65 to 89 years) women. Fat volume in the supraplatysmal and subplatysmal planes was quantified. Distribution of fat volume was assessed by dividing each supraplatysmal and subplatysmal compartment into upper, middle, and lower thirds. RESULTS: Total supraplatysmal fat volume was greater than subplatysmal in all patients. Young patients had more total supraplatysmal fat than old patients (p < 0.0001). No difference was found between age groups in subplatysmal fat (p > 0.05). No difference was found between upper/middle/lower third supraplatysmal fat volumes in young patients. When comparing supraplatysmal thirds within the elderly population, the middle third fat volume (28.58 ± 20.01 cm3) was greater than both upper (18.93 ± 10.35 cm3) and lower thirds (15.46 ± 11.57 cm3) (p < 0.01). CONCLUSIONS: This study suggests that total supraplatysmal fat volume decreases with age. Older patients had more fat volume in the upper and middle thirds compared with the lower third of the supraplatysmal fat compartment, whereas young patients had more evenly distributed fat. These results suggest that fat deposition and redistribution in the neck occur with age and may be a contributing factor to the obtuse cervicomandibular angle of the elderly.

National Variation of Insurance Coverage for Gender-Affirming Facial Feminization Surgery.

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.

Characteristics and Outcomes in Head and Neck Sarcomatoid Squamous Cell Carcinoma: The Cleveland Clinic Experience.

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.

Quantifying Aerosolization of Facial Plastic Surgery Procedures in the COVID-19 Era: Safety and Particle Generation in Craniomaxillofacial Trauma and Rhinoplasty.

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.

Dermal Filler Treatment Improves Psychosocial Well-Being in Facial Paralysis Patients.

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.

Platelet-Rich Plasma for Hair Restoration.

Platelet-rich plasma (PRP) is a promising treatment for hair restoration in patients with androgenic alopecia. Created from a platelet concentrate from an autologous blood draw, PRP is a safe therapeutic option for patients with hair loss. It is used alone or in conjunction with topical and oral therapies. Most studies of hair restoration with PRP report positive outcomes. Further research to optimize PRP preparation/administration procedures and identify patient populations that benefit most from this treatment are needed, as is long-term follow-up of objective hair loss outcomes. PRP appears to be a safe technology with excellent potential for promoting hair restoration.

Prospective Qualitative Multidimensional Assessment of the Postoperative Rhinoplasty Experience.

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.

Associations between national financial trends and facial plastic surgery procedural volume.

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.

Polytetrafluoroethylene granuloma-associated facial palsy following microvascular decompression.

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.

A Call for Universal Acceptance of the Milan System for Reporting Salivary Gland Cytopathology.

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.
