Ultrasonic Shears Decrease Postoperative Hematomas in Head and Neck Microvascular Reconstruction

OBJECTIVE

To evaluate postoperative hematoma and takeback rates in a large series of microvascular reconstructions. We sought to determine whether the use of ultrasonic shears reduced these rates.

STUDY DESIGN

Retrospective cohort study.

SETTING

Tertiary referral hospital.

METHODS

A total of 2288 patients undergoing free flap reconstruction for head and neck defects between 1995 and 2022 were reviewed. Patients undergoing dissection with and without ultrasonic shears were compared to determine postoperative hematoma and takeback rates.

RESULTS

The overall hematoma rate was 1.3% (29/2288) for the entire cohort. The postoperative hematoma rates with and without ultrasonic shears were 0.63% (9/1418) and 2.3% (20/870), relative risk = 0.28, P = .0015. Of 870 patients undergoing surgery without ultrasonic shears, 14 (1.61%) were taken back to the operating room for control of bleeding compared to 8 of 1418 (0.56%) in the ultrasonic shears cohort.

CONCLUSION

Our large series of patients undergoing microvascular reconstruction shows a decrease in postoperative hematoma rate and takeback for bleeding with the adoption of ultrasonic shears. Ultrasonic shears are an effective tool that can help decrease perioperative morbidity secondary to hematoma after head and neck tumor resection and microvascular reconstruction.

Postoperative inpatient surgical complications following head and neck microvascular free tissue transfer

BACKGROUND

Complications following head and neck microvascular free tissue transfer (MFTT) are common. Less is known about when they occur.

METHOD

Retrospective study of patients with primary or recurrent head and neck cancer undergoing MFTT reconstruction at a tertiary care institution. MFTT reconstructions with inpatient postoperative complications were included. The Kruskal-Wallis test was used to compare median postoperative day (POD) onset of complication by flap type.

RESULTS

Of 1090 patients undergoing MFTT reconstruction, 126 (11.6%) patients experienced inpatient complications including fibula (n = 35), anterolateral thigh (n = 60), or radial forearm (n = 31) MFTTs. POD onset was shortest for surgical site hematoma (median = 1 [IQR 1-5]), and longest for donor site infection (median = 11.5 [IQR 8-15]). There was no significant difference between flap types and POD onset of complications (p > 0.05).

CONCLUSION

Hematoma formation and flap failure occur earliest during hospitalization, while dehiscence, infection, and fistula occur later. There is no difference in complication timing between flap types.

The Impact of Venous Anastomosis Technique on Outcomes of Free Tissue Transfer to the Head and Neck

Objectives: To evaluate the impact of different techniques of microvascular venous anastomosis on the outcome of free tissue transfer to the head and neck. Methods: Retrospective case series of patients undergoing microvascular free tissue transfer (MFTT) from January 2006 to September 2021. Chi-square tests and t-tests were utilized to identify differences in flap outcomes by technique, and log-binomial regression analyses were utilized to identify differences in flap outcomes by technique. Results: A total of 1055 consecutive MFTTs were analyzed. One hundred four cases required a return to the operating room for any reason, and 19 were attributed to venous compromise (18.0%). Ultimately, there were 22 FTT failures requiring complete revision (2.1%). In total, 1055 MFTTs involved 1352 venous anastomoses, ranging from 1 to 3 anastomoses in each case. End-to-end (ETE) was used 1040 times (76.9%) and end-to-side (ETS) 204 times (15.0%). The calculated risk ratio for venous complication for ETS compared with ETE was 1.17 (0.34-3.98). A microvascular coupler was used in 355 cases (33.6%). The calculated risk ratio for coupler compared with suture anastomoses was 0.92 (0.35-2.39). Conclusions: There were no significant difference in regard to outcomes of MFTT when comparing ETE with ETS, nor when comparing coupler with suture anastomoses.

Systemic Therapy for Melanoma: ASCO Guideline Update Q and A

This Q&A answers questions regarding ASCO's recent Systemic Therapy for Melanoma guideline.

Increasing Pedicle Reach with Musculocutaneous Perforator Dissection in Anterolateral Thigh Free Flaps

OBJECTIVE

To measure the increase in effective pedicle reach with microdissection of musculocutaneous perforators during anterolateral thigh (ALT) free tissue harvest.

METHODS

A review of our institution's free flap database was performed to identify ALT free tissue transfers. The distance from pedicle vessel origin to its perforator's insertion at the fascia lata (effective pedicle length [EPL]) was measured prior to and following intramuscular dissection of musculocutaneous perforators. Pertinent clinicopathologic variables were abstracted from the electronic medical record.

RESULTS

A total of 314 ALT free flaps were performed between February 2017 and August 2022. Of these, 85 had documentation of EPL before and after musculocutaneous perforator dissection. ALT reconstruction was primarily performed for reconstruction of oncologic ablative defects (66, 78%). The mean EPL prior to perforator microdissection was 8.8 cm (standard deviation, SD 2.8 cm; range 3-15 cm). Following perforator dissection, mean EPL significantly increased to 14.0 cm (SD 3.0 cm; range 7-22 cm) with a mean net gain of 5.2 cm in distance (95% confidence interval 4.8-5.6 cm; p < 0.001). Nine patients (11%) required operating room take-back for anastomosis revision (3, 3.5%), recipient site hematoma evacuation (4, 4.7%), and wound dehiscence (2, 2.3%); one complete flap loss due to venous thrombosis was observed.

CONCLUSION

Dissection of musculocutaneous perforators during ALT free flap harvest can increase effective pedicle reach by 5.2 cm or nearly 60%. This harvest technique can facilitate the performance of tension-free anastomoses when substantial vascular pedicle length or vascular pedicle tunneling is required.

Through a New Lens: Skin-Grafted Free Flaps and Objective Facial Skin Color Matching

Background: Head and neck ablative surgery can impose aesthetic disfigurement, particularly when severe color mismatch exists between native and reconstructed facial skin. To date, the accuracy, objectivity, and modifiability of facial skin color matching remains poorly understood. Objective: To measure skin color match outcomes after head and neck reconstruction using handheld colorimetry. Methods: Patients undergoing complex head and neck reconstruction involving facial skin were included. A variety of skin paddle donor sites were studied, including split-thickness skin graft (STSG) placement over myocutaneous or adipofasciocutaneous free flaps after de-epithelization. Skin color match (deltaE) was measured during follow-up using a handheld colorimeter. Results: Forty-seven patients were included, with median age 69. The most common flap type was the anterolateral thigh (n = 31, 66%). Twenty patients underwent STSG to the skin paddle. DeltaE measurements among the patients with STSGs demonstrated better color match (lowest deltaE), compared with patients with unaltered skin paddles (3.4 ± 1.0 vs. 6.5 ± 2.5, p < 0.0001). Conclusion: We found the use of STSGs over de-epithelialized myogenous or adipofasciocutaneous flaps improves color match, as measured by handheld colorimetry.

Outcomes Associated with Multiple Free Tissue Transfers Performed in a Single Day

Background: Although microvascular free tissue transfer (MFTT) remains technically challenging, surgeons may need to perform >1 MFTT operations in a given day. Objective: To compare MFTT outcomes in cases where surgeons completed one versus two flaps per day by measuring flap viability and complication rates. Methods: A retrospective review was conducted of MFTT cases from January 2011 to February 2022 with >30-day follow-up. Outcomes, including flap survival and operating room takeback, were compared using multivariate logistic regression analysis. Results: Of 1096 patients meeting inclusion criteria (1105 flaps), there was a male predominance (n = 721, 66%). Mean age was 63.0 ± 14.4 years. Complications requiring takeback were identified in 108 flaps (9.8%) and were greatest for double flaps in the same patient (SP) (27.8%, p = 0.06). Flap failure occurred in 23 (2.1%) cases and was also greatest for double flaps in the SP (16.7%, p = 0.001). Takeback (p = 0.06) and failure (p = 0.70) rates were not different between days with one versus two unique patient flaps. Conclusions: Among patients undergoing MFTT, those treated on days in which surgeons perform two unique cases compared with single cases will demonstrate no difference in outcomes, as measured by flap survival and takeback, whereas patients with defects requiring multiple flaps will experience greater takeback and failure rates.

Systemic Therapy for Melanoma: ASCO Guideline Update

PURPOSE

To provide guidance to clinicians regarding the use of systemic therapy for melanoma.

METHODS

American Society of Clinical Oncology convened an Expert Panel and conducted an updated systematic review of the literature.

RESULTS

The updated review identified 21 additional randomized trials.

UPDATED RECOMMENDATIONS

Neoadjuvant pembrolizumab was newly recommended for patients with resectable stage IIIB to IV cutaneous melanoma. For patients with resected cutaneous melanoma, adjuvant nivolumab or pembrolizumab was newly recommended for stage IIB-C disease and adjuvant nivolumab plus ipilimumab was added as a potential option for stage IV disease. For patients with unresectable or metastatic cutaneous melanoma, nivolumab plus relatlimab was added as a potential option regardless of BRAF mutation status and nivolumab plus ipilimumab followed by nivolumab was preferred over BRAF/MEK inhibitor therapy. Talimogene laherparepvec is no longer recommended as an option for patients with BRAF wild-type disease who have progressed on anti-PD-1 therapy. Ipilimumab- and ipilimumab-containing regimens are no longer recommended for patients with BRAF-mutated disease after progression on other therapies.This full update incorporates the new recommendations for uveal melanoma published in the 2022 Rapid Recommendation Update.Additional information is available at www.asco.org/melanoma-guidelines.

Salivary Cortisol and Anxiety in Canadian Dentists over 1 Year of COVID-19

The dental profession has endured unprecedented disruption amid COVID-19. Novel stressors have included a high risk of occupational exposure to COVID-19, financial losses, and stricter infection prevention and control requirements. The present study investigated the longitudinal impact of COVID-19 on the stress and anxiety levels of a cohort of Canadian dentists (N = 222) between September 2020 and October 2021. Salivary cortisol was selected as a biomarker of mental stress, and 10 sets of monthly saliva samples (2,131 in total) were self-collected, sent to our laboratory in prepaid courier envelopes, and analyzed by enzyme-linked immunosorbent assay. To assess COVID-19 anxiety, 9 monthly online questionnaires were administered, comprising a general COVID-19 anxiety instrument and 3 items regarding the impact of dentistry-related factors. Bayesian log-normal mixed effect models were fitted to estimate the longitudinal trajectory of salivary cortisol levels and their association with the disease burden of COVID-19 in Canada. After accounting for age, sex, vaccination status, and the diurnal rhythm of cortisol secretion, a modest positive association was found between dentists' salivary cortisol levels and the count of COVID-19 cases in Canada (96% posterior probability). Similarly, the self-reported impact of dentistry-related factors, such as fear of getting COVID-19 from a patient or coworker, was greatest during peaks of COVID-19 waves in Canada; however, general COVID-19 anxiety decreased consistently throughout the study period. Interestingly, at all collection points, the majority of participants were not concerned about personal protective equipment. Overall, participants reported relatively low rates of psychological distress symptoms in relation to COVID-19, a result that should be reassuring for the dental community. Our findings strongly suggest a link between self-reported and biochemical measurements of stress and anxiety in Canadian dentists during the COVID-19 pandemic.

Opioid Overprescription and Underprescription to Patients After Otolaryngology-Head and Neck Surgery

This cohort study examines the extent of mismatched opioid prescribing between hospitalization and discharge after otolaryngology–head and neck surgery.

Assessing the Prevalence of Burnout Among Female Microvascular Head and Neck Surgeons

Background: Research has not explicitly explored differences between male and female microvascular head and neck (MHN) surgeon burnout, which should be identified and addressed to ensure career satisfaction and longevity. Objective: To measure and compare the prevalence of burnout among male versus female MHN surgeons. Methods: A prospective questionnaire based on the Maslach Burnout Inventory (MBI) was distributed through a web-based survey to the American Association of Facial Plastic and Reconstructive Surgeons and American Head and Neck Society in 2021 and 2022. Additional variables collected included demographics, relationship and parental status, academic rank, annual salary, and COVID-19-related questions. Results: One hundred thirteen surveys were collected. Twenty-nine (25.7%) were women and all completed MHN surgery fellowships. Women trended toward more emotional exhaustion than men (2.8 mean MBI vs. 2.3 mean MBI) but reported similar personal achievement (4.8 mean MBI vs. 4.9 mean MBI). Men experienced less workplace sexual harassment (p < 0.001). Women experienced more burnout (69% vs. 39%, p = 0.006) during the COVID-19 pandemic. Conclusion: Female MHN surgeons reported in this survey to experience more workplace sexual harassment and higher COVID-19-related burnout than their male counterparts.

Anterolateral Thigh Free Flap Versus Thigh Split Thickness Skin Graft: Comparison of Morbidity in the First 30 Days

Background: An anterior thigh split thickness skin graft (AT-STSG) is frequently needed to close the radial forearm free flap (RFFF) donor site, conferring morbidity to two extremities. The anterolateral thigh (ALT) free flap is virtually always closed primarily. Objective: To compare donor site pain, sensation, motor function, and cosmesis associated with the AT-STSG and the ALT. Methods: Patients undergoing an ALT or an RFFF with AT-STSG were enrolled in a prospective observational cohort study. Pain, tingling, numbness, lower extremity function, and subjective donor site cosmetic satisfaction were measured at 1 week and 1 month postoperation using validated instruments. Results: Forty-eight patients were included, with a mean age of 64.2 years (female 31.2%). There were no differences in age or medical comorbidities between the two groups. The average donor defect was 50 and 180 cm² for the AT-STSG and ALT cohorts, respectively. At 1 week and 1 month postoperatively, we did not detect a difference in donor site pain, pruritus, numbness or tingling, lower extremity function, or subjective cosmetic satisfaction between the two cohorts. Conclusion: ALT primary donor site morbidity, including pain, sensory function, motor function, and cosmesis, is equivalent to RFFF secondary donor site morbidity at 1 week and 1 month postoperatively.

Restarting Therapeutic Antibiotics Following Postoperative Prophylaxis in Head and Neck Microvascular Free Tissue Transfer

OBJECTIVE

To determine factors associated with restarting therapeutic antibiotics within 30 days of head and neck microvascular free tissue transfer (HN-MFTT).

STUDY DESIGN

Retrospective study of consecutive HN-MFTTs performed from January 2015 to July 2020.

SETTING

Tertiary academic medical center.

METHODS

Thirty-day postoperative antibiotic use and post-HN-MFTT surgical and medical complications were assessed. Univariable analyses and multivariable logistic regression were used to evaluate risk factors associated with restarting antibiotics.

RESULTS

overall 482 patients with 501 HN-MFTTs were stratified by duration of prophylaxis: ≤24 hours (n = 136, 27.1%), 25-72 hours (n = 54, 10.8%), and >72 hours (n = 311, 62.1%). Antibiotics were restarted in 199 patients (209 procedures, 42%). The most common indications for antibiotic reinitiation were flap recipient site infection (n = 59, 28%); hospital-acquired pneumonia (n = 44, 21%); and wound dehiscence, fluctuance, or change in quality of drain output (n = 44, 21%). Shorter antibiotic prophylaxis (≤24 hours) (odds ratio [OR], 1.95; 95% CI, 1.2-3.0; P = .003), osteocutaneous flaps (OR, 2.15; 95% CI, 1.3-3.4; P = .001), and prior immunotherapy/chemotherapy (OR, 2.29; 95% CI, 1.2-4.3; P = .01) were associated with reinitiation of antibiotics for surgical infections. Restarting antimicrobials for nosocomial infections was associated with aerodigestive defects (OR, 2.45; 95% CI, 1.1-5.2; P = .019), cardiovascular disease (OR, 3.00; 95% CI, 1.5-5.9; P = .001), and medical comorbidities approximated by American Society of Anesthesiologists class 3 or 4 (OR, 2.83; 95% CI, 1.5-5.4; P = .002).

CONCLUSION

Aerodigestive reconstruction, 24-hour postoperative antimicrobial prophylaxis, American Society of Anesthesiologists class 3 and 4, prior chemotherapy/immunotherapy, cardiovascular disease, and osteocutaneous flaps are associated with reinitiation of antibiotics within 30 days of HN-MFTT.

Objective Photoanalysis of Feminizing Frontal Cranioplasty Outcomes

Study Design

Retrospective analysis at a tertiary care center.

Objective

This study describes a method of analyzing postoperative results using lateral view clinical photographs to create normalized projection ratios of the glabella and radix.

Methods

We reviewed preoperative and postoperative photographs of 15 patients. All photographs were in the lateral view Frankfort horizontal plane. We calculated the distances between the (a) tragus and cornea, (b) cornea and radix, (c) cornea and glabella, and the (θ) nasofrontal angle.

Results

Fifteen sets of patient photographs were analyzed and found that there was a favorable 14% reduction at the radix and an even greater reduction (78.9%) at the glabella. The nasofrontal angle was improved to a more feminine range from 131.84° preoperatively to 145.86° postoperatively.

Conclusions

Normalized projection ratios of the glabella and radix, along with the nasofrontal angle, can be used to objectively measure outcomes of frontal feminizing cranioplasty.

Bilateral Superficial Trigeminal Nerve Blocks are not More Effective than a Placebo in Abolishing Post-operative Headache Pain in Pituitary Transsphenoidal Neurosurgery: A Prospective, Randomized, Doubleblinded Clinical Trial

BACKGROUND

Pituitary neurosurgery executed via the transsphenoidal endonasal approach is commonly performed for pituitary adenomas. Reasons for prolonged hospital stay include postoperative headache and protracted nausea with or without vomiting. Bilateral superficial trigeminal nerve blocks of the supra-orbital V1 and infra-orbital V2 (SION) nerves performed intra-operatively as a regional anesthetic adjunct to general anesthesia were hypothesized to decrease 6 hours postoperative morphine PCA (patient-controlled analgesia) use by patients.

METHODS

Forty-nine patients, following induction of general anesthesia for their transsphenoidal surgery, were prospectively randomized in a double-blinded fashion to receive additional regional anesthesia as either a block (0.5% ropivacaine with epi 1:200,000) or placebo/sham (0.9% normal saline). The primary endpoint of the study was systemic morphine PCA opioid consumption by the two groups in the first 6-hours postoperatively. The secondary endpoints included (1) pain exposure experienced postoperatively, (2) incidence of postoperative nausea and vomiting, and (3) time to eligibility for PACU discharge.

RESULTS

Of the 49 patients that were enrolled, 3 patients were excluded due to protocol violations. Ultimately, there was no statistically significant difference between morphine PCA use in the 6 hours postoperatively between the block and placebo/sham groups. There was, however, a slight visual tendency in the block group for higher pain scores, morphine use p=0.046, and delayed PACU discharge. False discovery rate corrected comparisons at each time point and then revealed no statistically significant difference between the two groups. There were no differences between the two groups for secondary endpoints.

CONCLUSION

It was found that a 6-hour postoperative headache after endoscopic trans-sphenoidal pituitary surgery likely has a more complicated mechanism involving more than the superficial trigeminovascular system and perhaps is neuro-modulated by other brain nuclei.

Objective Outcomes of Trichophytic Brow Lift and Hairline Advancement in Facial Feminization Surgery

Importance: The upper facial third is an important area to address in facial feminization surgery (FFS). Objective: This study seeks to quantify the changes in eyebrow, hairline, and forehead heights associated with brow lift and hairline advancement surgery in the transgender patient population. Design, Setting, and Participants: A cohort study performed at an academic medical center. Main Outcomes and Measures: Pre- and postoperative frontal view photographs underwent computer-aided photograph analysis. Brow position, hairline position, and forehead height were measured. Patient self-identified race, ethnicity, as well as other demographic factors were also collected. Results: Forty-six patients underwent FFS with brow lift and hairline advancement with photographs permitting measurement. Eyebrow analysis was performed in 33 patients. Hairline and forehead analyses were accomplished in 30 patients. The mean brow elevation was 4.6 mm across all locations. The forehead reduction achieved was 9.8-11.3 mm. Conclusion and Relevance: Trichophytic brow lifting with hairline advancement outcomes was able to be reliably quantified from standardized clinical photographs. On average, 4-5 mm of brow lift, 6-7 mm of hairline lowering, and 10-11 mm of forehead reduction were achieved, contributing to a more feminine appearance of the upper facial third.

Sex Differences in Adult Facial Three-Dimensional Morphology: Application to Gender-Affirming Facial Surgery

Background: Gender-affirming facial surgery (GFS) is pursued by transgender individuals who desire facial features that better reflect their gender identity. Currently, there are a few objective guidelines to justify and facilitate effective surgical decision making. Objective: To quantify the effect of sex on adult facial size and shape through an analysis of three-dimensional (3D) facial surface images. Materials and Methods: Facial measurements were obtained by registering an atlas facial surface to 3D surface scans of 545 males and 1028 females older than 20 years of age. The differences between male and female faces were analyzed and visualized for a set of predefined surgically relevant facial regions. Results: On average, male faces are 7.3% larger than female faces (Cohen's D = 2.17). Sex is associated with significant facial shape differences (p < 0.0001) in the entire face as well as in each sub-region considered in this study. The facial regions in which sex has the largest effect on shape are the brow, jaw, nose, and cheek. Conclusions: These findings provide biologic data-driven anatomic guidance and justification for GFS, particularly forehead contouring cranioplasty, mandible and chin alterations, rhinoplasty, and cheek modifications.

Outcomes of Vascularized Versus Nonvascularized Adipofascial Grafts for Parotidectomy Reconstruction

Objectives: Parotidectomy defects can leave patients with considerable functional and cosmetic deformities. We aim to compare the success rates and complications associated with vascularized versus nonvascularized adipofascial grafts for reconstruction, including flap failure, return to surgery, infection, and delay to adjuvant treatment. Methods: Retrospective case series of patients undergoing either adipofascial anterolateral thigh (AFALT) free tissue transfer or free fat transfer (FFT) after parotidectomy from January 2010 to January 2020. Group comparisons and logistic regression were used to determine predictors of outcome measures. Results: Seventy-six patients underwent AFALT reconstruction, and 73 patients underwent FFT reconstruction. Patients treated with AFALT reconstruction had more aggressive tumor characteristics and underwent more complex resections, most commonly radical parotidectomy (n = 55, 72.4%). Postoperative complications at both the donor and recipient sites were more common in the FFT group (N = 20, 27.4% in FFT vs. N = 11, 14.5% in AFALT, odds ratio = 0.45, 95% confidence interval = 0.20-1.02, p = 0.052). Conclusions: Although used in more advanced disease and in a more heavily treated wound bed, the AFALT free flap was safe and associated with fewer infectious complications than that offered by FFT.

Sex-Related Characteristics of the Face

The face is central to individual identity and gender presentation. Sex-based differences are seen at nearly every component of the face, from craniofacial structure to skin and soft tissue distribution. This article provides a framework for identification and analysis of sex-based differences in facial anatomy. This can then be used to guide individualized approaches to surgical planning to create greater congruence between patients' existing physical features and goals for gender expression.

Effect of microporous polysaccharide hemospheres on anterolateral thigh free flap donor site complications

Background

Postoperative seroma is the most common donor site complication following anterolateral thigh (ALT) free flap harvest for head and neck reconstruction. The utility of novel microporous polysaccharide hemospheres (MPH) has not been studied as a hemostatic agent in this setting.

Methods

Prospective, single‐blind, randomized controlled trial of patients undergoing fasciocutaneous ALT harvest for head and neck reconstruction at a tertiary academic medical center between April 2018 and February 2020. The intervention (MPH) group received 3 g of topical MPH to the ALT donor site prior to closure whereas the control group did not receive application of MPH. Outcomes included total drain output (ml), drain output during postoperative days (POD) 1–3 alone, drain duration (days), and incidence of donor site hematoma, seroma, or infection.

Results

Twenty‐nine patients were randomized to the MPH group and 26 to the control group. For MPH and control groups, mean total drain output was 284.7 ± 153.0 ml versus 317.9 ± 177.6 ml (p = .527), mean POD 1–3 drain output alone was 169.3 ± 88.8 ml versus 157.9 ± 78.7 ml (p = .749), and drain duration was 5.9 ± 1.5 days versus 6.5 ± 1.6 days (p = .144), respectively. There was no significant difference in seroma (p = .733), hematoma (p = .492), or infection (p = 1.000). Drain output was not significantly influenced by gender, age, body weight, or smoking habits.

Conclusion

MPH administration to ALT free flap donor sites did not significantly improve drain output, hematoma formation, or seroma formation.

Level of Evidence 2

Skin Color Match in Head and Neck Reconstructive Surgery

OBJECTIVES/HYPOTHESIS

To quantify the degree of color match achieved during microvascular facial reconstruction, and to describe a novel technique for improving reconstructive skin color match. We hypothesize that split-thickness skin grafts (STSG) placed atop de-epithelialized free tissue produces better facial skin color match than free tissue with intact epithelium.

STUDY DESIGN

Cross sectional photographic study of reconstructed facial skin color match.

METHODS

Sixty-eight adults, who underwent head and neck reconstructive surgery, were divided into six categories based on cutaneous reconstructive technique: cervicofacial flap, radial forearm free flap (RFFF), fibula free flap, anterolateral thigh free flap (ALT), STSG over adiopofascial flap (STAFF), and STSG over myogenous flap (STMF). Averaged color samplings of the reconstructed defect and adjacent normal skin were taken from digital photographs. The color difference was calculated using the delta-E calculation. Blinded expert observers also rated the degree of color match. Nonparametric cohort contrast and correlation statistical analyses were performed.

RESULTS

The mean delta-E's and 10-point Likert ratings for the ALT, fibula, RFFF, STAFF, STMF, and cervicofacial flaps were 11.6, 10.0, 7.7, 6.3, 8.8, and 4.7, and 5.1, 6.4, 2.4, 3.2, 2.7, and 1.1, respectively. Likert scale inter-rater correlation was strong, with coefficient = 0.80.

CONCLUSIONS

On average, STSG over de-epithelialized myogenous and adipofascial free tissue transfers produced a better color match than the skin paddles of donor sites, with the exception of the radial forearm donor site. Delta-E values obtained from photos correlated well with expert ratings of color match. This reliable technique for quantifying color match may be used in future studies.

Subcutaneous Soft Tissue Metastases in Lung Adenocarcinoma: A Surprising Initial Presentation on Bone Scintigraphy

ABSTRACT

Initial disease presentations are often surprising compared with expected clinical trajectories. We present a case of metastatic lung adenocarcinoma where the initial presentation was masquerading as a musculoskeletal soft tissue mass. Initial concern was for a hematoma after light trauma, but due to a pacemaker, MRI was contraindicated. Workup included a 99mTc-MDP bone scan where the lesion demonstrated activity. Further workup imaging was serendipitous, revealing a left upper lobe mass. Biopsy demonstrated poorly differentiated adenocarcinoma of lung origin. Soft tissue metastasis can occur with lung adenocarcinoma, and although it constitutes a less frequent metastatic route, it is nevertheless clinically important.

Gender-Affirming Facial Surgery: Experiences and Outcomes at an Academic Center

Background: Gender-affirming facial surgery (GFS) is becoming more widely available for transgender individuals, but data on surgical approaches and outcomes remain limited. Methods: Retrospective analysis of surgical outcomes among consecutive GFS cases performed at a tertiary care academic center between March 2016 and August 2020. Results: Seventy-seven patients underwent 109 surgeries, including 478 individual procedures. The median age was 42 years. Ninety-five percent of patients had public health insurance. Two-stage GFS was often used in older patients (p = 0.001), with the first stage involving bone and cartilaginous alterations, and the second stage involving soft tissue procedures. Mean hospital stay after first-stage GFS was 1.2 days, with 70% discharged on postoperative day 1. Mean follow-up was 11.3 months. Among 66 patients with at least 1 month of follow-up, all complications were minor and included surgical site infection (5%), dehiscence (3.0%), seroma (3%), and medical complications (6%). Thirty-day hospital readmission rate was 1.5%. Conclusions: There are unique surgical approaches for GFS, which demonstrate low complication and readmission rates. Understanding these approaches and outcomes may help guide preoperative patient consultations and clinical decision making.

Utility of Microporous Polysaccharide Hemosphere on Anterolateral Thigh Free Flap Donor Site Complications

Background: Anterolateral thigh (ALT) microvascular free tissue transfer is an integral part of head and neck reconstructive surgery, but it can be complicated by postoperative donor site fluid collections. Objective: To measure the rate of hematoma and seroma formation in the ALT donor site in those treated with microporous polysaccharide hemosphere (MPH) and those without. Methods: This was a retrospective cohort study examining patients undergoing ALT free tissue transfer for head and neck reconstruction at a single academic center between 2014 and 2017. Primary outcomes were interventional hematomas and seromas and drain duration. Results: In total, 118 patients underwent ALT free flap reconstruction for head and neck defects. Of these, 57 patients received MPH at the donor site and 61 did not. Eleven patients had a clinically significant seroma in the non-MPH group compared with three in the MPH group (p = 0.045). Drain duration for the MPH group compared with that for the non-MPH group was 6.9 versus 8.2 days (p = 0.020), and drains were removed when output was <60 mL over 24 h. Conclusion: This study supports the use of MPH in ALT free flap donor sites for reduction of clinically significant postoperative seromas. Further investigation with larger prospective randomized clinical trials is warranted.

Hepatitis C as a Potential Risk Factor for Adverse Surgical Outcomes in Head and Neck Free Tissue Transfer Reconstruction

Background: Infection with hepatitis C virus (HCV) is associated with an increased risk of developing head and neck cancer (HNC), and negatively impacts cancer-specific survival. Objective: To measure the impact of HCV status on free tissue transfer failure, flap takeback, and length of stay in HNC patients undergoing reconstruction. Methods: We retrospectively reviewed patients who underwent head and neck free tissue transfer reconstruction at a single academic institution between August 2011 and June 2020. Results: In the HCV-infected group, total flap failure rate was 2.9% versus 1.3% in the control group and the takeback rate was 11.1% versus 9.6%. On multivariate analysis, HCV status was not associated with flap failure, flap takeback, or total length of hospital stay >7 days. Conclusion: In this study, HCV status was not associated with differences in postoperative complications or length of stay. Future research with greater numbers of HCV-positive study subjects is required to elucidate the effect of HCV infection in this patient population.

Fibrolamellar Variant of Hepatocellular Carcinoma in a Young Female

Fibrolamellar variant of hepatocellular carcinoma (FLHCC) is a rare malignancy. Our patient presented to the hospital with increasing weight loss, decreased appetite, and night sweats. Imaging revealed a large liver mass and multiple pulmonary nodules concerning for metastasis. The patient eventually underwent interventional radiology (IR)-guided biopsy of the liver which revealed pathology consistent with FLHCC. The patient was discharged from the hospital and was scheduled for a follow up at an outpatient cancer center close to her family.

Facial Reanimation and Reconstruction of the Radical Parotidectomy

Radical parotidectomy may result from treating advanced parotid malignancies invading the facial nerve. Survival is often enhanced with multimodality treatment protocols, including postoperative radiation therapy. In addition to the reconstructive challenge of restoring facial nerve function, patients may be left with a significant cervicofacial concavity and inadequate skin coverage. This should be addressed with stable vascularized tissue that is resistant to radiation-induced atrophy. This article describes a comprehensive strategy, includes the use of the anterolateral thigh free flap, the temporalis regional muscle transfer, motor nerve to vastus lateralis grafts, nerve to masseter transfer, and fascia lata grafts for static suspension.

Patient-Reported Aesthetic and Psychosocial Outcomes After Microvascular Reconstruction for Head and Neck Cancer

Importance

Aesthetic outcomes are key determinants of psychosocial functioning among surgically treated patients with head and neck cancer (HNC); however, long-term aesthetic outcomes after microvascular free tissue transfer (MFTT) are not well described.

Objective

To examine risk factors for impaired long-term aesthetic satisfaction and appearance-related psychosocial functioning after HNC ablation with MFTT.

Design, Setting, and Participants

A cross-sectional, web-based survey was conducted at an academic tertiary care center. A total of 228 individuals who underwent MFTT between January 1, 2015, and December 31, 2019, for treatment of HNC were included. The study was conducted from November 1, 2020, through January 15, 2021.

Exposures

Head and neck cancer ablation with MFTT.

Main Outcomes and Measures

Patient-reported outcomes were assessed via Aesthetic FACE-Q scales. The primary objective was aesthetic satisfaction determined by the Satisfaction With Facial Appearance scale. Secondarily, the Appearance-Related Psychosocial Distress, Psychological Function, and Social Function scales were used to assess appearance-related psychosocial functioning. Patients were stratified by demographic, disease, surgical, and postoperative characteristics. Survey scores on a 100-point scale were compared and subjected to univariable and multivariable linear regression.

Results

A total of 124 of 228 patients (54.4%) completed surveys a median of 34.4 months after MFTT (interquartile range, 22.6-48.8). Most responders (79 [63.7%]) were men with advanced cancer of the oral cavity or skin, reconstructed with anterolateral thigh or osteocutaneous fibula free flaps. Nonresponders had no significant differences in baseline characteristics. The Satisfaction With Facial Appearance score was independently lower among patients who received osteocutaneous flaps (regression coefficient, -10.6 points, 95% CI, -20.4 to -0.8 points) and/or adjuvant (chemo)radiotherapy (regression coefficient, -6.9 points; 95% CI, -13.8 to -0.1 points). Impaired appearance-related psychosocial functioning was independently associated with female sex, a history of anxiety or depression, osteocutaneous flaps, prolonged tube feeding requirements, and any recurrent or persistent disease. After adjustment for covariates, each 1-point increase in the Satisfaction With Facial Appearance score independently estimated improved appearance-related psychosocial functioning as determined by the Appearance-Related Psychosocial Distress scale (regression coefficient, -0.5 points; 95% CI, -0.7 to -0.4 points), Psychological Function scale (regression coefficient, 0.4 points; 95% CI, 0.3 to 0.5 points), and Social Function scale (regression coefficient, 0.4 points; 95% CI, 0.3 to 0.6 points).

Conclusions and Relevance

The findings of this cross-sectional, web-based survey study suggest that osteocutaneous reconstruction and adjuvant therapy independently increase the risk of poor patient-reported long-term aesthetic satisfaction, which correlated with impaired appearance-related psychosocial functioning. Aesthetic outcomes appear to be a priority to address in patients with HNC undergoing MFTT.

Smile Outcomes of an Externally Scarless, Intraoral Orthodromic Temporalis Tendon Transfer

Background: Temporalis tendon transfer (TTT) often relies on external incisions in the nasolabial fold, temporal region, or both. Herein, we studied smile outcomes of a TTT technique via a single intraoral incision without external skin incisions. Objective: To measure the difference in static perioral positions before and after intraoral TTT. Methods: Five patients underwent an externally scarless TTT technique via an intraoral approach. Iris measurements were used to estimate pixel-to-millimeter conversion for facial analysis of vertical and horizontal oral commissure excursion vectors using the JAVA-based program Facegram version 1.0 (Massachusetts Eye & Ear Infirmary). Results: After surgery, mean vertical height on the affected side significantly increased from 3.4 mm to a postoperative value of 20.6 mm, p = 0.016. There was no difference in horizontal smile excursion after surgery (35.7 mm vs. 32.2 mm, p = 0.37). Smile angle difference between affected and healthy smile (Δα) reduced from 27.0° preoperative to 3.5°, representing a decrease in facial asymmetry (p = 0.002). Conclusion: Intraoral, externally scarless TTT is an effective option for dynamic facial reanimation, obviating external incisions in select patients.

Surveillance Imaging Following Head and Neck Cancer Treatment and Microvascular Reconstruction

OBJECTIVES/HYPOTHESIS

To assess the accuracy and utility of positron emission tomography/computed tomography (PET/CT) compared with magnetic resonance imaging (MRI) for detecting head and neck cancer (HNC) recurrence after microvascular reconstructive surgery.

STUDY DESIGN

Retrospective cohort study.

METHODS

Analysis of HNC patients who underwent microvascular reconstruction at a single, tertiary academic center following ablative surgery from 1998 to 2015. Forty-six patients aged 61.4 ± 15.8 years with both PET/CT and MRI examinations were identified. Two radiologists were blinded and interpreted each imaging study. Recurrence certainty scores were determined via continuous (0-100) and Likert ("Likely" to "Unlikely") scales, with larger values indicating a higher likelihood of recurrence. Pathologic confirmation of recurrence was confirmed in 23 patients (50%).

RESULTS

Among those with primary site recurrences, mean recurrence certainty was significantly higher with PET/CT versus MRI on the continuous scale (63.9 vs. 44.4, P = .006). A receiver operating characteristic analysis for predicting primary site recurrence demonstrated a significantly larger area under the curve of 0.79 for PET/CT compared to 0.64 for MRI (P = .044). Categorization of "Likely" primary site recurrence on PET/CT, versus MRI, had higher sensitivity (0.63 vs. 0.40), but lower specificity (0.90 vs. 1.0). MRI demonstrated higher sensitivity (1.0 vs. 0.78) at detecting regional site recurrences.

CONCLUSION

PET/CT demonstrates greater sensitivity than MRI as a surveillance tool for primary site recurrence following microvascular reconstruction where clinical evaluation is hindered by anatomical distortion. Therefore, PET/CT should be pursued as first-line imaging, with MRI utilized for confirmation of positive imaging findings at the primary site.

Modelling rheumatic heart disease progression in australia using disease register data linked to administrative records

Funding Acknowledgements

Type of funding sources: Public grant(s) – National budget only. Main funding source(s): Australian Government National Health and Medical Research Council

OnBehalf

ERASE project

Background

Rheumatic Heart Disease (RHD) is a major contributor to morbidity and mortality globally, and is endemic among Indigenous Australians. The RHD Endgame strategy was recently launched, outlining comprehensive methods for eliminating RHD in Australia by 2031. However, there is currently limited information on national rates of RHD and progression to severe or complicated RHD.

Purpose

This study provides current estimates of RHD progression prior to RHD Endgame Strategy implementation. We estimate the probability and predictors of progressing from RHD diagnosis to cardiovascular complications, death, or need for surgical intervention in the Australian population from expanded data sources, addressing methodological shortcomings in existing evidence by using cross-jurisdictional administrative datasets and a competing risks approach.

Methods

This retrospective cohort study used linked RHD register, hospital and death data from five Australian jurisdictions (&gt;70% Australians). Progression from RHD diagnosis to all-cause mortality, non-fatal cardiovascular complications (heart failure, stroke, endocarditis, atrial fibrillation), or need for surgical intervention were estimated for people aged &lt;35years diagnosed with first-ever RHD between 2010 and 2018. A minimum 8.5-year look-back excluded prevalent cases; maximum follow-up was 8 years. Proportional cause-specific hazard regression modelling investigated independent predictors of outcomes, with death treated as a competing risk.  Sensitivity analyses compared results between all-sources and register-only cohorts.

Results

We identified 1714 first-ever RHD cases aged &lt;35years in the all-sources cohort (84% Indigenous, 11% migrant, 63% women, 40% age 5-14years, 85% non-metropolitan). Six months after diagnosis, 8.1% (95%CI:6.9-9.5%) had experienced heart failure, other cardiovascular complications or surgical intervention and 23.6% (95%CI:20.2-27.5%) progressed to these outcomes within 8 years. The register-only cohort experienced less disease progression with estimated composite event rates of 5.6% (95%CI:4.7-6.6%) and 18.4% (95%CI:16.6-20.5%) at 6 month and 8 years respectively. Death rate in the all-sources cohort was 0.5% at 6 months and 3.2% at 8 years. Older age, Metropolitan residence, and history of acute rheumatic fever, but not sex or Indigenous status, were independent predictors of major cardiovascular outcomes.

Conclusions

This study provides the most definitive and contemporary estimates of RHD disease progression in young Australians. Despite Australia"s excellent healthcare system infrastructure, RHD complication rates remain high.  Improvements in healthcare systems for diagnosis, monitoring, and management of RHD cases will need to be implemented in both Metropolitan and remote settings as Australia implements its Endgame strategy against RHD. However, primordial and primary prevention provides the best potential to reduce the burden of RHD in Australia and beyond.

Appearance-Related Distress and Social Functioning after Head and Neck Microvascular Reconstruction

OBJECTIVES/HYPOTHESIS

To better understand aesthetic patient-reported outcomes and psychosocial quality of life (QOL) after head and neck microvascular reconstruction for benign or malignant tumors.

STUDY DESIGN

Single-center prospectively obtained in-office validated questionnaire-based study.

METHODS

Analysis of prospectively collected surveys at a tertiary care academic center from June 2018 to February 2021. Patients completed two FACE-Q scales: Appearance-Related Psychosocial Distress (ARPD) and Social Function (SF). Survey scores, demographics, operative course, and adjuvant therapy data underwent univariate and multivariable analyses.

RESULTS

One hundred and three patients completed surveys at a median of 13.5 months postoperatively (interquartile range: 5.2-30.8). Mean ARPD from 0 (no distress) to 100 (maximum distress) was 32.4 (standard error of the mean [SEM]: 2.7). Mean SF from 0 (worst functioning) to 100 (best functioning) was 55.5 (SEM: 2.7). Postoperative adjuvant radiation was associated with 13.9% higher ARPD (95% CI: 3.4-24.4, P = .019) and 10.4% lower SF (95% CI: -20.7 to -0.1, P = .047). Each appearance-related question on the ARPD scale independently predicted impaired SF (P < .001 for all questions). Upon multivariable logistic regression, osteocutaneous reconstruction, compared to soft tissue alone (P = .043), and postoperative adjuvant radiation (P = .014) were associated with higher levels of ARPD. Age, sex, relationship status, anxiety or depression history, defect location, and hospital stay were not significantly associated with ARPD or SF scores.

CONCLUSIONS

Aesthetic outcomes are important determinants of psychosocial QOL following head and neck microvascular reconstruction: an effect that is worsened by adjuvant radiation. Reconstructive surgeons should prioritize aesthetic outcomes, in addition to functional restoration, to optimize social functioning in patients with head and neck tumors.

Patient tracking during treatment of children with cancer in India - An exploratory study

BACKGROUND

Abandonment of treatment, a major cause of treatment failure in low- and middle-income countries like India, is particularly high during the diagnostic and initial phase of treatment. Tracking of patients during this risk period may reduce treatment abandonment rates and increase quality of care.

AIM

The primary aim was to pilot the use and check the acceptability of a tool for tracking children with cancer in New Delhi during the initial part of their treatment. Secondary aim was to estimate abandonment rates among these patients.

METHODS

This prospective study was carried out in two centers of North India in New Delhi and enrolled children less than 18 years diagnosed with cancer at these centers and who had registered with Cankids for social support. Parent support group (PSG) workers maintained contact with the child's family at least once a week for the first 12 weeks. Details of each contact and subsequent action were recorded in a customized book (called "You are not alone" or YANA Book). Descriptive analysis of these contacts was done in Microsoft Excel and presented in frequencies and percentages. The five-point Likert scale was used to check the acceptability of the tool among the PSG workers.

RESULTS

Seven PSG workers enrolled and tracked 81 patients (73% male with a median age of 6 years). During the 12-week study period, 986 contacts were attempted and three (3.7%) patients had abandoned their treatment. All PSG workers strongly agreed that the YANA book was simple to understand and use, decreased their workload, and helped provide better assistance to patients.

CONCLUSION

The tool for patient tracking was well accepted by the PSG workers and considered easy to use. We now plan to implement our model as a routine service at all the partnering hospitals in India.

Risk Factors for and Cost Implications of Free Flap Take-backs: A Single Institution Review

OBJECTIVE/HYPOTHESIS

For patients undergoing microvascular free tissue transfer (MFTT), we evaluated risk factors and financial implications of operating room (OR) take-back procedures.

STUDY DESIGN

Retrospective review at a tertiary care center.

METHODS

Patients who underwent MFTT for head and neck reconstruction from 2011 to 2018 were identified. We compared hospital length of stay and overall costs associated with OR take-back procedures. Multivariable regression analysis evaluated factors associated with OR take-backs during the same hospitalization.

RESULTS

A total of 727 free flaps were reviewed, and 70 OR take-backs (9.6%) were identified. Mean total length of stay (LOS) in the ICU was 3.4 days versus 6.7 days for non-take-back and take-back flaps, respectively (P < .001). Mean total LOS on the regular floor was 6.3 days versus 13.1 days, respectively (P < .001). This resulted in a cost differential of $33,507 (94.3% increase relative to non-take-back flaps). The total cost associated with an OR take-back was $39,786. Hematomas were the most common cause of take-backs and wound dehiscence was associated with the highest costs. On multivariable analysis, higher ASA class (OR, 2.06; 95% CI, 1.11-3.99; P = .026) and shorter ischemia times (OR, 0.52; 95% CI, 0.29-0.95; P = .030) were independently associated with increased risk of take-backs.

CONCLUSIONS

OR take-backs infrequently occur but are associated with a significant increase in financial burden when compared to free flap cases not requiring OR take-back. The large majority of the cost differential lies in a substantial increase of ICU and floor LOS for take-back flaps when compared to non-take-back flaps.
