Primary Targeted Muscle Reinnervation in Above-Knee Amputations in Patients with Unsalvageable Limbs from Limb-Threatening Ischemia or Infection.

BACKGROUND: Amputees frequently suffer from chronic pain in both their residual limbs (RLP) and phantom limbs (PLP) following their amputation. Targeted muscle reinnervation (TMR) is a nerve transfer technique that has been demonstrated to improve pain secondarily and at time of amputation. The goal of this study is to report on the efficacy of primary TMR at time of above-knee level amputations in the setting of limb-threatening ischemia or infection. METHODS: This is a retrospective review of a single-surgeon experience with TMR in patients undergoing through- or above-knee level amputations from January 2018 to June 2021. Patient charts were reviewed for the comorbidities in the Charlson Comorbidity Index. Postoperative notes were assayed for presence and absence of RLP and PLP, overall pain severity, chronic narcotic use, ambulatory status, and complications. A control group of patients undergoing lower limb amputation who did not receive TMR from January 2014 to December 2017 was used for comparison. RESULTS: Forty-one patients with through- or above-knee level amputations and primary TMR were included in this study. The tibial and common peroneal nerves were transferred in all cases to motor branches to the gastrocnemius, semimembranosus, semitendinosus, and biceps femoris. Fifty-eight patients with through- or above-knee level amputations without TMR were included for comparison. The TMR group had significantly less overall pain (41.5 vs. 67.2%, p = 0.01), RLP (26.8 vs. 44.8%, p = 0.04), and PLP (19.5 vs. 43.1%, p = 0.02). There were no significant differences in complication rates. CONCLUSION: TMR can safely and effectively be performed at time of a through- and above-knee level amputation and improves pain outcomes.

Below-the-knee Amputation with Targeted Muscle Reinnervation: Operative Technique and Technical Pearls.

Postamputation pain from symptomatic neuromas and/or phantom limb pain can have a significant detrimental impact on patients' quality of life following a major lower extremity amputation. Various methods of physiologic nerve stabilization, such as targeted muscle reinnervation (TMR) and regenerative peripheral nerve interface, have been proposed as the best current techniques to prevent that pathologic neuropathic pain. Methods: This article details our institution's technique that has been performed safely and effectively on over 100 patients. Our approach and rationale for each of the major nerves of the lower extremity are presented. Results: In contrast to other described techniques for TMR for below-the-knee amputations, this current protocol does not involve performing transfers on all five major nerves, as one must balance rates of symptomatic neuroma formation and nerve-specific phantom limb pain with needed operative time and surgical morbidity from removing proximal sensory function and denervation of the donor motor nerve branches. This technique also differs significantly from others by performing a transposition of the superficial peroneal nerve to place the neurorrhaphy away from the weight-bearing stump. Conclusion: This article details our institution's approach to physiologic nerve stabilization via TMR at time of below-the-knee amputation.

Perioperative misgendering experiences in patients undergoing gender-affirming surgery: a call for a gender-inclusive healthcare environment.

Background: Transgender individuals have long experienced discrimination and exclusion from medicine. Misgendering occurs when an individual is referred to using a gender or address incongruent with their identity. We evaluated the incidence of misgendering throughout the perioperative experience for patients undergoing gender-affirming surgery (GAS). Methods: Patients diagnosed with gender dysphoria who previously received GAS by the senior author were contacted to complete an IRB-approved survey to evaluate instances of misgendering while in the hospital for GAS. Study results were summarized using descriptive statistics. Results: Of 471 patients contacted, 182 completed the survey (38.6%). The most cited gender identity was transfemale (28.0%). Most patients reported respect for their gender identity (60.4%) and name (76.8%) during their perioperative experience. Twenty-two percent cited triggering experiences, and 15.4% reported interactions with healthcare employees causing them to reach out to a support system. Misgendering most commonly included incorrect use of patients' preferred names and/or pronouns (n = 50, 86.2%), most commonly at surgical check-in (n = 10, 45.5%). Recommendations to improve feelings of gender congruence during patients' stay included updated names and gender identities in electronic medical records (80.8%), and names and pronouns listed on curtains and doors (52.3%) and name tags (51.5%). Conclusions: Until now, the exact incidence of misgendering among patients seeking GAS have not been well established. Despite high levels of satisfaction, a large proportion still reported serious instances of misgendering. Improvements must be made to the perioperative experience to reduce misgendering and provide support and comfort during the sensitive period surrounding patients' gender transition.Level of evidence: Not gradable.

Selecting a chest masculinization plastic surgeon: a survey of transgender patients.

Background: Chest masculinization is a commonly performed gender-affirming procedure in transmasculine and non-binary patients and has increased in prevalence in recent years despite continued barriers to surgical care. With the expansion of insurance coverage and trained surgeons, patients at times have the opportunity to be selective in choosing their gender-affirming surgeon. This study aimed to investigate factors that transmasculine individuals consider important when selecting their chest masculinization plastic surgeon. Methods: All patients who underwent chest masculinization with a single surgeon between January 2018 and December 2021 were surveyed via an online questionnaire to rate 21 factors associated with surgeon selection. Multiple-choice questions and free text space were included to further clarify patient preferences. Results were analyzed to rate factors in order of importance. Results: One hundred three individuals completed the survey, generating a response rate of 49.5%. Average patient age at time of surgery was 27.0 years, and 2.0% of patients had prior gender affirmation surgery (GAS). The top five most important factors were surgeon specialization in GAS, insurance coverage, board certification, number of times surgeon has performed procedure, and availability of Before and After photographs. The five least important factors were age of surgeon, medical publications, availability of YouTube videos, location of training, and surgeon presence on social media. Conclusions: Transmasculine patients employ distinct criteria when selecting a chest masculinization gender-affirming plastic surgeon. An improved understanding of these factors informs providers of ways to enhance patient access to information and gender-affirming care.Level of evidence: Not gradable.

A Pilot Investigation into Targeted Muscle Reinnervation for Complex Regional Pain Syndrome, Type II.

Complex regional pain syndrome (CRPS) is a debilitating condition, characterized by severe pain with vascular, motor, or trophic changes. Varied presentations make this a diagnostic and therapeutic challenge. There is a lack of high-quality evidence demonstrating efficacy for most existing therapies, particularly with surgical intervention for type II CRPS (CRPS-II). Targeted muscle reinnervation (TMR) is a surgical technique to transfer the terminal end of a divided nerve to a recipient motor nerve, shown to limit phantom limb pain, residual limb pain, and postamputation neuroma pain. Methods: Herein, we describe a series of 13 patients undergoing TMR for CRPS-II by a single surgeon from 2018 to 2021 in the upper (38%) and lower extremities (62%). All patients had a diagnosis of CRPS-II with either traumatic or postsurgical etiology, each seeking TMR with or without concomitant treatment to control their pain after previous therapies had failed. Three patients had previous lower extremity amputation, whereas three others received lower extremity amputation at the time of TMR, each indicated for control of CRPS pain. Results: Of the patients receiving TMR within 1 year of CRPS diagnosis, all three reported improved function, and two patients were able to tolerate a prosthetic for ambulation after previous pain prevented prosthetic use. Of the entire cohort, all but one patient reported reduced pain interference or improved function. Conclusions: These outcomes suggest that TMR may provide some benefit to reducing pain severity patients with CRPS, even after a more chronic disease course. Further prospective trials are warranted.

Prevalence of Comorbid Psychiatric Conditions and Chronic Pain in Patients Seeking Peripheral Nerve Surgery.

Background: In peripheral nerve surgery, the presence of psychiatric diagnoses and medications may affect outcomes and perioperative neuropathic pain management. The purpose of this study was to determine the prevalence of psychiatric diagnoses and chronic pain in patients referred to a peripheral nerve surgery clinic. Methods: This is a retrospective review of patients seen at a peripheral nerve clinic from July 1, 2017 to June 30, 2021. Medical records were reviewed for demographics; peripheral nerve diagnosis; psychiatric diagnoses; psychotropic prescriptions; use of nonneuroleptic/nonnarcotic, neuroleptic, and narcotic medications; and peripheral nerve surgical candidacy and outcome. Results: Six hundred twenty-two patients were included in this study. The most common reasons for referral were 24.8% lower extremity neuroma, 23.2% lower extremity compressive neuropathy, and 14.0% upper extremity compressive neuropathy. Of the included patients' 37.1% had a psychiatric diagnosis, and 36.3% were taking a psychotropic medication. The percentage of patients taking chronic nonneuroleptic/nonnarcotic pain medications was 34.3%' with 42.8% taking neuroleptic, and 24.9% narcotic medications. Patients with a psychiatric diagnosis were more likely to be taking neuroleptic (48.9% versus 38.9%, P < 0.001) and narcotic pain medications (27.3% versus 17.4%, P = 0.004) and less likely to have a positive surgical outcome (65.7% versus 83.0%, P = 0.001). Conclusions: Patients referred to a peripheral nerve surgery clinic frequently have psychiatric diagnoses and take chronic psychotropic and chronic pain medications. Knowledge of this will best help the peripheral nerve surgeon evaluate a patient for surgery, optimize perioperative care, and safely and effectively manage expectations.

Facial Feminization Surgery: A Systematic Review of Perioperative Surgical Planning and Outcomes.

Background: Facial feminization is a critical step in a transfeminine patient's surgical transition. However, the existing literature on the various types of feminization surgeries suffers from inadequate reporting on perioperative aspects of care, such as preoperative evaluation and postoperative outcomes. The aim of this study is to evaluate facial feminization surgery (FFS), preoperative planning, and patient reported outcomes after various types of procedures. Methods: An electronic database search of Ovid MEDLINE was completed according to PRISMA guidelines for articles pertaining to FFS. Study characteristics, operative information, and patient demographics were collected. Data concerning preoperative imaging, virtual simulation, postoperative complications, and patient-reported outcome measures (PROMs) were collected and analyzed for patterns. Results: A total of 22 papers representing 1302 patients were included for analysis. The most commonly discussed operations included upper face procedures, particularly of the forehead (17 studies, 77%). When discussed, preoperative planning for FFS included standard photography in 19 (86%) studies, advanced imaging, such as cephalometry or computed tomography, in 12 (55%) studies, and virtual simulation of surgical outcomes in four (18%) studies. Patient-centered outcomes, such as postoperative satisfaction, were described in 17 (77%) studies. Standardized PROMs were heterogenous across included studies with only 11 (50%) including at least one PROM. Conclusions: FFS is common, safe, and highly satisfying for transfeminine patients seeking surgical intervention for identity actualization. Future research concerning transgender care must evaluate advanced surgical planning and 3D simulation combined with more standardized assessment of PROMs to ensure high-quality analysis of patient satisfaction.

Incidence and Nerve Distribution of Symptomatic Neuromas and Phantom Limb Pain after Below-Knee Amputation.

BACKGROUND: Patients with major lower limb amputations suffer from symptomatic neuromas and phantom-limb pain due to their transected nerves. Peripheral nerve surgery techniques, such as targeted muscle reinnervation and regenerative peripheral nerve interface, aim to physiologically prevent this nerve-specific pain. No studies have specifically reported on which nerves most frequently cause chronic pain. The authors studied the nerve-specific incidence of symptomatic neuroma formation and phantom limb pain in patients undergoing a below-knee amputation, to better tailor use of targeted muscle reinnervation and regenerative peripheral nerve interface. METHODS: This was a retrospective review of all patients undergoing a below-knee amputation from January 1, 2013, to December 31, 2018, at MedStar Georgetown University Hospital. All below-knee amputations were performed with a posterior skin flap, myotenodesis, and traction neurectomies of all nerves. Postoperative notes were reviewed for the presence of a symptomatic neuroma, defined as localized pain and a Tinel sign over a known sensory nerve, and nerve-specific phantom limb pain, defined as pain of the missing limb corresponding to a known dermatome. RESULTS: One hundred ninety-eight patients were included in this study. The rate of symptomatic neuroma formation was 14.6 percent (29 of 198), with the superficial peroneal and saphenous nerves most often involved. Diabetes and obesity were protective against symptomatic neuroma formation. The rate of nerve-specific phantom limb pain was 12.6 percent (25 of 198) and highly correlated with the presence of a symptomatic neuroma. CONCLUSION: To optimize outcomes for amputees, it is critical that surgeons best understand what nerves are more likely to form symptomatic neuromas and lead to nerve-specific phantom limb pain, so that surgeons can best tailor primary or secondary management of the major sensory nerves. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

Targeted Muscle Reinnervation Improves Pain and Ambulation Outcomes in Highly Comorbid Amputees.

BACKGROUND: Approximately 200,000 people undergo a lower extremity amputation each year. Following amputation, patients suffer from chronic pain, inability to ambulate, and high mortality rates. Targeted muscle reinnervation is a nerve transfer procedure that redirects transected sensory and mixed nerves into motor nerves to treat neuroma and phantom limb pain. This study evaluates outcomes with prophylactic targeted muscle reinnervation at the time of below-knee amputation. METHODS: This is a cohort study comparing 100 patients undergoing below-knee amputation with primary targeted muscle reinnervation and 100 patients undergoing below-knee amputation with standard traction neurectomy and muscle implantation. Outcome metrics included the presence of residual and phantom limb pain, pain severity, opioid use, ambulation ability, and mortality rates. RESULTS: The targeted muscle reinnervation group was on average 60 years old with a body mass index of 29 kg/m2. Eighty-four percent had diabetes, 55 percent had peripheral vascular disease, and 43 percent had end-stage renal disease. Average follow-up was 9.6 months for the targeted muscle reinnervation group and 18.5 months for the nontargeted muscle reinnervation group. Seventy-one percent of targeted muscle reinnervation patients were pain free, compared with 36 percent (p < 0.01). Fourteen percent of targeted muscle reinnervation patients had residual limb pain, compared with 57 percent (p < 0.01). Nineteen percent of targeted muscle reinnervation patients had phantom limb pain, compared with 47 percent (p < 0.01). Six percent of targeted muscle reinnervation patients were on opioids, compared with 26 percent (p < 0.01); and 90.9 percent of targeted muscle reinnervation patients were ambulatory, compared with 70.5 percent (p < 0.01). CONCLUSION: Targeted muscle reinnervation reduces pain and improves ambulation in patients undergoing below-knee amputation, which may be critical in improving morbidity and mortality rates in this comorbid patient population. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Retention Sutures and Negative Pressure Wound Therapy for Delayed Primary Closure of Fasciotomy Wounds.

Achieving primary closure of lower extremity fasciotomy wounds is difficult. Surgeons are faced with the option of waiting potentially long periods of time for edema to reside, in order to attempt delayed primary closure (DPC) versus closing at an earlier time with a split thickness skin graft. DPC offers superior aesthetic outcomes than split thickness skin grafts but traditionally cannot occur until later in the clinical course once excessive edema has subsided. We present a case of a young athlete with compartment syndrome, which was managed with an alternative technique for achieving DPC: serial partial closure under tension with retention sutures and negative pressure wound therapy. The successful outcome in this single case should prompt further studies investigating the objective benefits of this novel method to achieve DPC following fasciotomy.

Targeted Muscle Reinnervation to Expendable Motor Nerves for the Treatment of Refractory Symptomatic Neuromas in Nonamputees.

Symptomatic neuromas can cause debilitating pain, significantly impairing patients' quality of life. There are numerous medical and surgical options for management. Targeted muscle reinnervation (TMR) is a nerve transfer procedure that is now commonly used to prevent or treat symptomatic neuromas or phantom limb pain in amputees. There are a few reports in the current literature about performing TMR in the nonamputee, but no cohort studies to date that report pain outcomes. This study evaluates TMR to treat symptomatic neuromas in nonamputee patients. This is a retrospective cohort study of all patients with symptomatic neuromas treated with TMR over a 1-year period from January 1,2019, to January 1, 2020, at MedStar Georgetown University Hospital. The neuromas are excised to healthy nerve fascicles, and a redundant donor motor fascicle is selected for nerve transfer. Patients were asked in clinic or via telephone about their preoperative and postoperative pain, function, and quality of life, and postoperative clinic notes were reviewed for complications and motor deficits. Fifteen patients were included in this study. Patients had symptomatic neuromas involving the upper extremity, lower extremity, and trunk. Pain frequency decreased from 6.7 times per week to 3.9 (P < 0.01) and from 9.1 times per day to 5.1 (P < 0.01). Pain severity decreased from an average of 7.9/10 to 4.3/10 (P < 0.01). Overall physical function increased from 3.7/10 to 5.8/10 (P = 0.01), and overall quality of life increased from 4.9/10 to 7.0/10 (P < 0.01). No patients had demonstrable weakness of the motor function of the donor nerve. Targeted muscle reinnervation is a viable surgical option for the treatment of symptomatic neuromas, particularly in those patients who have previously failed prior neuroma excisions.

Locoregional Options for Acute Volar Pulp Fingertip Defects.

The volar fingertip is a unique anatomic structure, delicate yet durable, that allows us to navigate the world, acquire information from our surroundings, and express ourselves. Injuries to the volar finger can cause permanent dysfunction and should be taken seriously. In treating injuries of the volar fingertip, the surgeon has an opportunity to choose from a host of reconstructive options and provide the patient with an outcome suitable to their needs. In doing so, the hand surgeon is well-positioned to aim for the reconstructive ideal of restoring both structure and function.

The Reducing Opioid Use in Children with Clefts Protocol: A Multidisciplinary Quality Improvement Effort to Reduce Perioperative Opioid Use in Patients Undergoing Cleft Surgery.

BACKGROUND: Cleft repair requires multiple operations from infancy through adolescence, with repeated exposure to opioids and their associated risks. The authors implemented a quality improvement project to reduce perioperative opioid exposure in their cleft lip/palate population. METHODS: After identifying key drivers of perioperative opioid administration, quality improvement interventions were developed to address these key drivers and reduce postoperative opioid administration from 0.30 mg/kg of morphine equivalents to 0.20 mg/kg of morphine equivalents. Data were retrospectively collected from January 1, 2015, until initiation of the quality improvement project (May 1, 2017), tracked over the 6-month quality improvement study period, and the subsequent 14 months. Metrics included morphine equivalents of opioids received during admission, administration of intraoperative nerve blocks, adherence to revised electronic medical record order sets, length of stay, and pain scores. RESULTS: The final sample included 624 patients. Before implementation (n =354), children received an average of 0.30 mg/kg of morphine equivalents postoperatively. After implementation (n = 270), children received an average of 0.14 mg/kg of morphine equivalents postoperatively (p < 0.001) without increased length of stay (28.3 versus 28.7 hours; p = 0.719) or pain at less than 6 hours (1.78 versus 1.74; p = 0.626) or more than 6 hours postoperatively (1.50 versus 1.49; p = 0.924). CONCLUSIONS: Perioperative opioid administration after cleft repair can be reduced in a relatively short period by identifying key drivers and addressing perioperative education, standardization of intraoperative pain control, and postoperative prioritization of nonopioid medications and nonpharmacologic pain control. The authors' quality improvement framework has promise for adaptation in future efforts to reduce opioid use in other surgical patient populations. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Defining Risk of Postoperative Obstructive Sleep Apnea in Patients With 22q11.2DS Undergoing Pharyngeal Flap Surgery for Velopharyngeal Dysfunction Using Polysomnographic Evaluation.

OBJECTIVE: To determine pre- and postoperative prevalence of obstructive sleep apnea (OSA) in patients with 22q11.2 deletion syndrome (DS) undergoing wide posterior pharyngeal flap (PPF) surgery for velopharyngeal dysfunction (VPD). DESIGN: Retrospective study using pre- and postoperative polysomnography (PSG) to determine prevalence of OSA. Medical records were reviewed for patients' medical comorbidities. Parents were surveyed about snoring. SETTING: Academic tertiary care pediatric hospital. PATIENTS: Forty patients with laboratory confirmed 22q11.2DS followed over a 6-year period. INTERVENTIONS: Pre- and postoperative PSG, speech evaluation, and parent surveys. MAIN OUTCOME MEASURE: Severity and prevalence of OSA, defined by obstructive apnea hypopnea index (OAHI), before and after PPF surgery to determine whether PPF is associated with increased risk of OSA. RESULTS: Mean OAHI did not change significantly after PPF surgery (1.1/h vs 2.1/h, P = .330). Prevalence of clinically significant OSA (OAHI ≥ 5) was identical pre- and postoperatively (2 of 40), with both cases having severe-range OSA requiring positive airway pressure therapy. All other patients had mild-range OSA. Nasal resonance was graded as severe preoperatively in 85% of patients. None were graded as severe postoperatively. No single patient factor or parent-reported concern predicted risk of OSA (OAHI ≥ 1.5). CONCLUSIONS: Patients with 22q11.2DS are medically complex and are at increased risk of OSA at baseline. Wide PPF surgery for severe VPD does not significantly increase risk of OSA. Careful perioperative planning is essential to optimize both speech and sleep outcomes.

Palatal Measurements Pre- and Post-Furlow Cleft Palate Repair: Analysis of Palatal Lengthening and Comparison Within Cleft Types.

OBJECTIVE: The purpose of this study was to characterize intraoperative palatal lengthening with the modified Furlow cleft palatal repair and to determine whether lengthening correlated with preoperative cleft width, cleft type, or operating surgeon. DESIGN: Retrospective study. SETTING: Academic tertiary care pediatric hospital. PATIENTS: One hundred eighty pediatric patients undergoing primary or secondary palatoplasty using the Furlow technique. INTERVENTIONS: Cleft and palatal lengths and widths were measured pre- and post-Furlow cleft palatal repair. MAIN OUTCOME MEASURES: Immediate postoperative percentage change in surface palate length, straight palate length, and soft palate length. RESULTS: The average cleft widest width and width at the hard-soft palate junction were 10.2 and 9.5 mm, respectively, and varied with Veau cleft type. Following Furlow palatoplasty, lengths of the curved, straight, and soft palate increased by 7.5%, 15.8%, and 30.6%, respectively. Degree of palatal lengthening varied among surgeons and Veau cleft type but was not related to cleft width. Seven (4.0%) patients developed postoperative oronasal fistulas. Patients with a Veau IV cleft and larger cleft widths were at an increased risk for fistula formation. CONCLUSIONS: This study demonstrates that overall palatal lengthening occurs with the modified Furlow technique. Long-term follow-up studies are needed to determine the clinical relevance of these findings.

Variations in Cardiac Arrest Regionalization in California.

INTRODUCTION: The development of cardiac arrest centers and regionalization of systems of care may improve survival of patients with out-of-hospital cardiac arrest (OHCA). This survey of the local EMS agencies (LEMSA) in California was intended to determine current practices regarding the treatment and routing of OHCA patients and the extent to which EMS systems have regionalized OHCA care across California. METHODS: We surveyed all of the 33 LEMSA in California regarding the treatment and routing of OHCA patients according to the current recommendations for OHCA management. RESULTS: Two counties, representing 29% of the California population, have formally regionalized cardiac arrest care. Twenty of the remaining LEMSA have specific regionalization protocols to direct all OHCA patients with return of spontaneous circulation to designated percutaneous coronary intervention (PCI)-capable hospitals, representing another 36% of the population. There is large variation in LEMSA ability to influence inhospital care. Only 14 agencies (36%), representing 44% of the population, have access to hospital outcome data, including survival to hospital discharge and cerebral performance category scores. CONCLUSION: Regionalized care of OHCA is established in two of 33 California LEMSA, providing access to approximately one-third of California residents. Many other LEMSA direct OHCA patients to PCI-capable hospitals for primary PCI and targeted temperature management, but there is limited regional coordination and system quality improvement. Only one-third of LEMSA have access to hospital data for patient outcomes.

Perioral Rejuvenation: A Prospective, Quantitative Dynamic Three-Dimensional Analysis of a Dual Modality Treatment.

BACKGROUND: The perioral region is the most dynamic anatomic area of the face and subject to complex and dramatic changes during aging. Successful treatment for perioral rejuvenation has yet to be identified, and prior studies have reported only subjective outcomes. OBJECTIVES: The purpose of this study was to utilize our validated dynamic 3-dimensional imaging technology to determine whether conservative neuromodulation combined with hyaluronic acid filler volumization can decrease perioral strain and increase volume with significant patient satisfaction. METHODS: An IRB-approved prospective study of a dual modality treatment for perioral rhytids was performed on females with perioral aging who had not had prior facial treatment within the past year. Eighteen (18) units of Dysport were injected into the upper and lower orbicularis oris and 1 cc of Restylane Silk was injected in volume-depleted perioral regions in each patient. Each patient underwent imaging with digital image correlation (DIC) and completed the FACE-Q survey prior to injection and at 14 days and 90 days postinjection. RESULTS: Thirty-two female patients were recruited. A significant reduction in perioral strain was observed at both day 14 and day 90. This was concomitant with a significant increase in perioral volume at day 14 that at 90 days was significantly retained in the marionette lines. Further, there was a significant improvement in patient satisfaction with overall facial appearance at day 14 that was maintained at 90 days. CONCLUSIONS: Conservative neuromodulation and hyaluronic acid filler volumization of the perioral region produces a significant reduction in strain correlating with high patient satisfaction, even at 90 days. This dual modality treatment is effective in rejuvenating the perioral region, and its future optimization will provide greater therapeutic options for this anatomically complex area.

Gender-Affirming Surgery in Persons with Gender Dysphoria.

The landscape of gender dysphoria has changed dramatically in recent years secondary to increased societal acceptance, legislative changes, and medical providers' increased awareness of the associated psychosocial burden associated with the diagnosis. National and global advocacy efforts, in conjunction with expanded third-party insurance coverage, have resulted in new health care opportunities for patients suffering from gender dysphoria. Delivering quality, streamlined health care to these patients requires a complex multidisciplinary approach, involving multiple medical and mental health disciplines, including plastic surgeons. To accommodate the expanding demand for gender-affirmation surgery, academic medical centers specializing in these procedures are gradually emerging. Advancing surgical techniques in the setting of rising patient demand encourage plastic surgeons to increasingly provide high-quality health care to this diverse patient population in an effort to optimize psychosocial functioning and minimize the burden of gender dysphoria. Although the current literature is replete with the evolving surgical and technical approaches to gender-affirming surgery, there remain critical gaps in the plastic surgery literature describing the delivery of comprehensive care to these patients. To address these gaps, the authors establish a framework that plastic surgeons can use to guide their management of patients with gender dysphoria to optimize surgical and psychosocial outcomes. First, the authors describe a timeline of events that have shaped present-day transgender medicine and characterize the current role of the plastic surgeon in the management of gender dysphoria. Subsequently, the authors discuss psychosocial and ethical considerations surrounding gender dysphoria. Finally, the authors discuss the future scope of transgender medicine.

Quantifying Pediatric Facial Palsy: : Using Digital Image Correlation to Objectively Characterize Pediatric Facial Symmetry.

OBJECTIVE: This study introduces digital image correlation (DIC) as a novel technology to objectively quantify pediatric facial symmetry. DESIGN: Descriptive cohort study of patients' facial symmetry as measured by DIC. SETTING: Academic tertiary care hospital. PATIENTS: 9 of 12 identified facial palsy and 13 of 26 identified control subjects participated. INTERVENTIONS: DIC was used to quantify facial strain and symmetry as patients made the 5 standard Sunnybrook facial expressions. Each subject was evaluated according to the Sunnybrook scale by 4 evaluators, 3 plastic surgeons, and 1 occupational therapist. MAIN OUTCOME MEASURE: The percentage asymmetry values were calculated and compared between the facial palsy and control groups using both DIC and Sunnybrook. RESULTS: Using DIC, facial palsy subjects had 32.99% asymmetry compared with 14.84% in controls (P < .01). Using Sunnybrook, facial palsy subjects had 24.11% asymmetry compared to 3.87% in controls (P < .01). The 2 metrics were positively correlated (P < .01). There was significant variability among the Sunnybrook evaluators (P = .02). CONCLUSIONS: DIC is a novel technique of objectively quantifying facial motion of the animated face. As surgical and medical approaches toward facial palsy expand, it is essential to have a means to compare results and improve patient outcomes.
