RESUMO

Post-rhinoplasty pain control should use a multimodal regimen. Evidence suggests decreasing routine prescriptions of narcotics is reasonable for most individuals, and acetaminophen and nonsteroidal antiinflammatory drug combinations may be equivalent to as-needed opioids for postsurgical pain management. Preoperative pain counseling is important to set post-rhinoplasty pain expectations and reduce opioid use. A single intravenous dose of prophylactic antibiotics before incision is sufficient for most cases of functional rhinoplasty. Additional considerations are given to complex revision cases, use of allogenic grafts or implants, external osteotomies, or patients with immunosuppression or at risk of endocarditis.

RESUMO

Augmented reality (AR) technology has become widely established in otolaryngology-head and neck surgery. Over the past 20 years, numerous AR systems have been investigated and validated across the subspecialties, both in cadaveric and in live surgical studies. AR displays projected through head-mounted devices, microscopes, and endoscopes, most commonly, have demonstrated utility in preoperative planning, intraoperative guidance, and improvement of surgical decision-making. Specifically, they have demonstrated feasibility in guiding tumor margin resections, identifying critical structures intraoperatively, and displaying patient-specific virtual models derived from preoperative imaging, with millimetric accuracy. This review summarizes both established and emerging AR technologies, detailing how their systems work, what features they offer, and their clinical impact across otolaryngology subspecialties. As AR technology continues to advance, its integration holds promise for enhancing surgical precision, simulation training, and ultimately, improving patient outcomes.

RESUMO

OBJECTIVE: To evaluate the effect of prophylactic antibiotics on outcomes and complications following surgical reconstructions of nasal Mohs defects in the outpatient setting. STUDY DESIGN: Retrospective cohort study. SETTING: Single tertiary care center, July 2021 to June 2023. METHODS: All adult patients who underwent reconstruction of nasal Mohs defects in an outpatient office setting were examined. Patient demographics, surgical details, prophylactic postprocedural antibiotic use, and postprocedural complications (infection, flap or graft necrosis, wound dehiscence) were collected. Outcomes and complications were compared between patients who received and did not receive prophylactic antibiotics using χ2, Kruskal-Wallis, and multivariable logistic regression. RESULTS: A total of 211 patients met inclusion criteria. A majority of reconstructions utilized a local flap (70%), followed by a skin or composite graft (22%), then an interpolated flap (8%). Over half of patients (55%) were prescribed prophylactic antibiotics. Postprocedural complications were documented in 16 patients (7.6%), including infection (3.3%) and flap or graft loss or necrosis (1.4%). The rate of complications did not differ based on receipt of antibiotics. The only factors independently associated with the development of complications were history of chemoradiation and reconstruction with skin or composite grafts. CONCLUSION: Prophylactic antibiotics after nasal Mohs reconstructions performed in the office setting were not associated with any differences in the rate of postprocedural complications, including surgical site infections.

RESUMO

OBJECTIVE: Few studies have examined the impact of preoperative and surgical factors on the change in cosmetic survey scores after nasal Mohs reconstruction using a subset of the 10-item Standardized Cosmesis and Health Nasal Outcomes Survey-Cosmesis (SCHNOS-C). We aim to determine preoperative and surgical factors that impact cosmetic outcomes following Mohs nasal reconstruction. STUDY DESIGN: Retrospective analysis. SETTING: Nasal Mohs reconstruction patients at a tertiary medical center. METHODS: All patients receiving Mohs reconstruction of any nasal subunit at a tertiary medical center were analyzed. Variables collected included demographic and Mohs defect/reconstruction characteristics. Primary outcomes were changes in cosmetic (SCHNOS-C) scores and revision rates. Multivariable analysis was used to identify independent predictors of cosmetic scores/revision. RESULTS: We included 296 patients for analysis. On multivariable logistic regression, factors contributing to better final cosmetic scores were receiving a skin/composite graft (odds ratio [OR]: 0.22, 95% confidence interval: 0.06-0.68, P = .014) compared to a local flaps. Women were more likely to have worsening cosmetic scores (OR: 2.27, 1.06-4.99, P = .037). Only initial cosmetic scores independently predicted receiving any revision (OR: 1.11, 1.03-1.20, P = .006). CONCLUSION: Average SCHNOS-C scores after nasal reconstruction of Mohs defects are low. Only worse patient reported SCHNOS-C scores predicted revision. It is important to understand preoperative and surgical factors that affect cosmetic outcomes to optimize patient counseling and reconstructive planning. Patient perception is a key factor in predicting revisions.

RESUMO

Background: Little is known about how depression and appearance anxiety affect patient reporting of synkinesis severity. Learning/Study Objective: Measure prevalence of depression and appearance anxiety in facial synkinesis and correlations between subjective and surgeon-graded synkinesis severity. Design Type: Prospective cohort. Methods: Patients with synkinesis volunteered and completed: Synkinesis Assessment Questionnaire (SAQ), facial clinimetric evaluation (FaCE) scale, Center for Epidemiological Studies Depression Scale (CES-D), and Fear of Negative Appearance Evaluation Scale (FNAES). Standardized videos were scored by facial plastic surgeons using Sunnybrook Scale and eFaCE. Multivariate linear regression was used to compare patient- and surgeon-graded metrics. Results: One hundred patients participated, 91 were female. Mean age was 56.4 (12.3). Eight percent identified as Black and 87% White. The most common nerve injury etiology was idiopathic (47%). Mean synkinesis duration was 7.6 years (6.2). Twenty percent and 15% reported history of an anxiety or depressive disorder, respectively. Patient (SAQ, FaCE) and clinician (Sunnybrook, eFaCE) scores were correlated (Pearson's r 0.223-0.294, p < 0.05). Upon adjusting for CES-D/FNAES, correlations between most patient and clinician metrics became stronger. As CES-D and FNAES worsened, patient-clinician correlations weakened. Conclusions: Depression and appearance anxiety may affect patient reporting of synkinesis severity. Worse mental health scores may decorrelate patient and clinician synkinesis assessments.

RESUMO

OBJECTIVE: Surgical management of cleft lip/palate and cleft rhinoplasty have historically been performed by plastic surgeons. No study has addressed temporal trends in cleft-associated surgeries. This study assesses trends in cleft surgical management and complications in a national database. METHODS: Cross-sectional analysis of the National Surgical Quality Improvement Program Pediatric database from 2012 to 2021. Patients receiving cleft lip and/or palate repair were isolated using CPT codes. A subset receiving cleft rhinoplasty was also analyzed. The yearly proportion of otolaryngologists compared to general plastic surgeons performing surgeries was noted. Regression analysis was used to identify trends and predictors of management by OHNS. RESULTS: We identified 46,618 cases of cleft repair, of which 15.6% (N = 7,255) underwent repair with otolaryngology. On univariate Pearson correlation analysis, neither cleft rhinoplasties performed by OHNS over time (R = 0.371, 95% CI -0.337 to 0.811, p = 0.2907) nor all cases (R = -0.26, -0.76 to 0.44, p = 0.465) exhibited a significant change. On multivariable regression, the operative year was not associated with being treated by otolaryngology (p = 0.826) for all cleft cases but was associated with such in cleft rhinoplasties (OR 1.04, 1.01-1.08, p = 0.024). On multivariable analysis, the operative year was correlated with a higher rate of complications overall (OR 1.04, 1.01-1.07, p = 0.002). Surgeon specialty was not associated with complication rates. CONCLUSIONS: In the last 10 years, no change in the proportion of cleft lip/palate repair performed by OHNS was observed. Otolaryngologists are performing more cleft rhinoplasty but at a marginal rate. Otolaryngologists also manage more complex patients with multiple comorbidities compared to their colleagues. Complication rates have increased overall regardless of surgeon specialty, warranting further investigation. LEVEL OF EVIDENCE: 3 Laryngoscope, 134:671-677, 2024.

RESUMO

OBJECTIVES: Microtia and anotia repair require techniques that consider both aesthetics and function. The outcomes of different reconstructive frameworks such as costal cartilage or a porous polyethylene implant have not been evaluated on a national scale. We aim to understand differences in outcomes/complication rates and operative times between different reconstructive frameworks used in microtia/anotia reconstruction. METHODS: This was a retrospective review of the National Surgical Quality Improvement Program Pediatric database between 2012-2019. Patients with ICD-9/10 codes for microtia/anotia were isolated. Reconstruction methods were identified using CPT codes for rib graft, ear cartilage graft, and alloplastic implants (biocompatible implants, porous polyethylene, etc). Outcomes included operative-time, wound complications, and unplanned re-operations within 30 days of surgery. Multivariable logistic regression was performed to control for confounders. RESULTS: We included 593 patients for analysis. Reconstruction with rib grafts (N = 506, 85%) was the most common. In 58 patients (9.8%), an implant was used for the auricular framework, whereas in 47 (7.9%) ear cartilage grafts were used. The overall wound complication rate was 3.4%. On univariate analysis, alloplastic implants exhibited a higher rate of wound complications (8.6% vs. 2.8%, p = 0.037) and longer operative times (350 min vs. 235 min, p < 0.001). After controlling for demographics and comorbidities, implants conferred an independently increased risk of wound complications (OR 3.52, 1.10-9.54, p = 0.020). CONCLUSION: Although the use of alloplastic implants (e.g., porous polyethylene) may confer an increased risk of early complications, the long-term clinical implications of these findings are unclear relative to aesthetic benefits. Multi-institutional studies are needed to validate these findings using patient-specific and surgeon-specific data. LEVEL OF EVIDENCE: 3 Laryngoscope, 134:1214-1219, 2024.

RESUMO

BACKGROUND: Management of facial fractures is variable. Understanding how time to operative management impacts outcomes can help standardize practice. METHODS: Retrospective analysis of the ACS Trauma Quality Improvement Program (TQIP) database between 2016 and 2019. Adult patients with operative facial fractures were isolated by ICD-10 procedure codes, and further stratified by fracture location, including the mandible, orbit, maxilla, zygoma, and frontal bone. Multivariable logistic regression was conducted to predict in-hospital complications (both surgical and systemic complications) adjusting for time-to-operation, comorbidities, fracture location, AIS, and demographics. RESULTS: 1678 patients with operative facial fractures were identified. The median time-to-operation was 2 days (IQR 1.0-2.0 days). Most patients only had one operative fracture (95 %) and orbital fracture was the most common (44 %). The overall complication rate was higher for those operated after 2 days compared to those operated between 1 and 2 days and within 24 h (2.8 % vs 0.6 % vs 0.7 %; p < 0.001). Patients who were operated on after 48 h exhibited an increased risk of any complication (OR 4.72, 95 % CI 1.49-16.6, p = 0.010) on multivariable models. CONCLUSION: Delays in the management of facial fractures are associated with more in-hospital complications. However, the incidence of short-term postoperative complications remains low. Injury characteristics are the primary predictor of delays in operation, however Hispanic patients independently experienced delays in care.

RESUMO

Background: The paramedian forehead flap (PMFF) is a well-established technique utilized for reconstruction of complex nasal defects. Objective: To identify the different techniques and management of patients undergoing PMFF reconstruction and compare these with current literature. Methods: Members of the American Academy of Facial Plastic and Reconstructive Surgery were sent a practice survey highlighting various nuances in PMFF reconstruction. The survey included questions about flap design, operative techniques, and perioperative care. Results: In total, 172 responses were received (14% response rate). Mean years of practice after fellowship was 15.8 years with most respondents performing either 1-5 (33.1%) or 6-10 (27.3%) PMFFs per year. Common practices included the use of general anesthesia, elevation of PMFF in the subgaleal plane (59.6%), and pedicle division at 3 weeks (80%) (p < 0.001). Complication rates ranged between 1% and 5%. The nose was the most common site for revision (p < 0.001) and the average number of secondary procedures after forehead flap division was 1.1 (standard deviation 0.81). The most variability in responses was seen for methods of internal lining reconstruction. Conclusion: Reconstructive surgeons frequently divide the PMFF pedicle at 3 weeks or later and have variable approaches to reconstruction of the internal lining with low complication rates overall.

RESUMO

OBJECTIVES: Evaluation of potential gender gaps among Head and Neck (H&N) surgeons can highlight areas for increased support of female H&N surgeons and improve gender diversity within the subspecialty. To evaluate gender trends in representation and career trajectory among recent H&N surgery fellowship graduates. METHODS: This cross-sectional analysis included graduates from Head and Neck Surgery fellowships accredited by the American Head and Neck Society (AHNS) from 2008 to 2018. Additional demographic data was collected via publicly available websites including gender, years in practice, practice location, type of practice, h-index, and academic rank. The primary outcomes were the proportion of female Head and Neck fellowship graduates and gender trends in career trajectory and academic productivity (via h-index). RESULTS: Between 2008 and 2018, 449 surgeons graduated from Head and Neck surgery fellowship with females comprising 99 of 449 graduates (22%). Female representation increased from 1 of 30 (3%) graduates in 2008 to 17 of 52 (33%) in 2018. A proportionally similar number of women graduating fellowship also practiced in an academic setting (23%). There were fewer female assistant, associate and full professors compared with their male counterparts. Women had lower h-indices compared with men even when controlling for years in practice (mean 11.4 vs. 8.2, p < 0.03). CONCLUSION: Despite the increase in women graduating from H&N surgery fellowships, gender disparities within academic rank and academic productivity as measured by h-index remain. While a proportional number of women completing fellowship are entering academic practice, additional investigation and support is needed to address the potential gender gaps identified within academic H&N surgery.

RESUMO

This review provides a comprehensive presentation of the evidence available in facial reconstruction post-Mohs micrographic surgery. Given the large diversity in post-Mohs reconstruction, there are limited guidelines in the management of defects. The aim of the present work is to provide a review of the best evidence as it pertains to several considerations in facial reconstruction. Data suggests that Mohs micrographic surgery and many reconstructive procedures can be performed as outpatient procedures under local anesthesia, with narcotic pain medication only given in certain patient populations following a minority of reconstructive procedures. Perioperative and topical antibiotics are generally not indicated. Aspirin and warfarin can generally be continued for most reconstructive procedures, but clopidogrel and novel anticoagulants may predispose to increased bleeding complications. Delayed reconstruction appears to be safe, although data are discordant on this topic. No specific wound closure technique or suture choice appears to be consistently superior. Given the lack of robust comparative studies, consistent methodology, and variable defect sizes/locations, no robust evidence-based guidelines can be generated for reconstruction techniques of facial subsites.

RESUMO

Background: The Nasal Obstruction Symptom Evaluation (NOSE) scale is widely used by clinicians in evaluation of nasal airway obstruction (NAO). Objective: To determine normative values for the NOSE scale among both symptomatic and asymptomatic members of the general U.S. population. Methods: A survey of NAO symptoms in adults of age 18 years and older was performed. The distribution of NOSE scores among the general population was estimated. Influence of features including age, gender, race, location, and symptomatology on NOSE scores was evaluated. Results: Surveys were completed by 2333 participants. Mean NOSE score was 11 (standard deviation [SD] 11) in the asymptomatic, and 28 (SD 22) in the symptomatic population (p < 0.0001). Increasing age was associated with an increase in scores until 45 years, after which it was associated with decreasing scores. No significant differences were found related to other investigated demographics. Conclusions: Normative ranges for the NOSE scale are established, and are largely consistent with values in the existing literature. NOSE scores do not appear to be influenced by gender, race, or geography, although age should be considered in their interpretation.

RESUMO

BACKGROUND: Social media is an important tool for networking, recruitment, and promoting clinical practice. No study has specifically assessed which FPRS practitioners have professional social media accounts, how they utilize them, and what barriers or resources exist to their use. OBJECTIVES: This study aims to examine differences in social media use based on provider demographics and practice setting, and identify resources and barriers to professional social media use. METHODS: This cross-sectional analysis was an anonymous survey sent to AAFPRS members. Data collected included demographics, practice setting, resources, and barriers encountered to use of professional social media. RESULTS: Most facial plastic surgeons (80%) use professional social media, notably Instagram and Facebook, and mostly post patient photos and stories (67.9%). Social media is more commonly utilized in private practice (56% vs 23%, P = .0016), where there are less institutional barriers (10% vs 40%, P = .02) and more resources available (82.5% vs 12.5%, P = .01). CONCLUSIONS: Social media is widely used in FPRS. Working in private practice is associated with increased availability of resources for support, and a reduction in institutional barriers to maintaining a social media presence. With this understanding, facial plastic surgeons can be better equipped for networking, marketing, and promoting the field of FPRS.

RESUMO

Background: Patients with facial synkinesis may have jaw tightness and swallow discomfort despite chemodenervation of facial mimetic musculature, and the posterior belly of the digastric (PBD) muscle is a logical target to treat these symptoms. Learning/Study Objective: To compare patient-reported outcomes of botulinum toxin (BT) chemodenervation of the posterior belly of digastric muscle in patients with postparalytic facial synkinesis. Design Type: Retrospective review. Methods: Patients with facial synkinesis who underwent electromyography (EMG)-guided PBD BT chemodenervation in addition to their baseline therapeutic regimen were included. Pre- and post-treatment Synkinesis Assessment Questionnaires (SAQ) and a two-question survey regarding jaw tightness and swallow discomfort were administered. Results: Twenty-nine patients were included. An average of 5 U of BT-A was injected into the PBD, and 46.5 U across all facial muscles. From pre- to post-injection, patients demonstrated improvement in jaw tightness at rest (3.02 vs. 1.98/5.0, p < 0.001), with swallow (2.78 vs. 1.94/5.0, p < 0.001), and total SAQ (64.3 vs. 51.2/100, p < 0.001). Patients rated subjective benefit from PBD injection compared with prior treatments without PBD injection as 4.5/5.0. Conclusion: Synkinesis patients with jaw tightness or swallow discomfort may benefit from the addition of PBD injections to the therapeutic regimen.

RESUMO

OBJECTIVES/HYPOTHESIS: Despite increasing the numbers of women entering the field, underrepresentation of women in otolaryngology has been reported. In the subspecialty of facial plastic and reconstructive surgery (FPRS), female representation and academic leadership have not been formally characterized. Our study aims to identify female representation and academic leadership roles in FPRS. STUDY DESIGN: Cross sectional analysis. METHODS: Analysis was performed using the 2020 American Academy of Facial Plastic and Reconstructive Surgery (AAFPRS) membership directory. Board-eligible and board-certified FPRS surgeons were included. Data regarding academic rank, leadership position, academic productivity, and years in practice were collected from publicly available departmental websites. Academic productivity was measured using h-index. RESULTS: Of 1,421 members queried in the 2020 AAFPRS membership directory, 13.0% were female and 86.9% were male. Most practitioners (87.0%) work in a private practice setting, but of the 13.0% of academic FPRS surgeons, 25.9% were female. Most female facial plastic surgeons in academic practice were Assistant Professors (72.9%), whereas ranks were evenly distributed among male FPRS surgeons. Three (4.3%) of 69 AAFPRS fellowship directors were women, and 1 (1.8%) of 56 present or past AAFPRS presidents was female. Female FPRS surgeons had fewer years in practice and lower h-indices compared with male surgeons. CONCLUSIONS: Female FPRS surgeons hold fewer academic leadership positions and have lower academic productivity in comparison to male FPRS surgeons. Future studies are needed to elucidate the etiology of these gender differences. LEVEL OF EVIDENCE: NA Laryngoscope, 132:781-785, 2022.

RESUMO

Developing immunosuppressive therapies for autoimmune diseases comes with a caveat that immunosuppression may promote the risk of developing other conditions or diseases. We have previously shown that biolistic delivery of an expression construct encoding inducible HSP70 (HSP70i) with one amino acid modification in the dendritic cell (DC) activating moiety 435-445 (HSP70iQ435A) to mouse skin resulted in significant immunosuppressive activity of autoimmune vitiligo, associated with fewer tissue infiltrating T cells. To prepare HSP70iQ435A as a potential therapeutic for autoimmune vitiligo, in this study we evaluated whether and how biolistic delivery of HSP70iQ435A in mice affects anti-tumor responses. We found that HSP70iQ435A in fact supports anti-tumor responses in melanoma-challenged C57BL/6 mice. Biolistic delivery of the HSP70iQ435A-encoding construct to mice elicited significant anti-HSP70 titers, and anti-HSP70 IgG and IgM antibodies recognize surface-expressed and cytoplasmic HSP70i in human and mouse melanoma cells. A peptide scan revealed that the anti-HSP70 antibodies recognize a specific C-terminal motif within the HSP70i protein. The antibodies elicited surface CD107A expression among mouse NK cells, representative of antibody-mediated cellular cytotoxicity (ADCC), supporting the concept, that HSP70iQ435A-encoding DNA elicits a humoral response to the stress protein expressed selectively on the surface of melanoma cells. Thus, besides limiting autoimmunity and inflammation, HSP70iQ435A elicits humoral responses that limit tumor growth and may be used in conjunction with immune checkpoint inhibitors to not only control tumor but to also limit adverse events following tumor immunotherapy.
