The profunda artery perforator flap for head and neck reconstruction.

INTRODUCTION: The profunda artery perforator (PAP) fasciocutaneous flap is underutilized in head and neck reconstruction, with advantages including ease of harvest and minimal donor site morbidity. METHODS: Cadaveric dissection of cutaneous perforators to origin at profunda femoris system to characterize vascular anatomy. RESULTS: 22 PAP flaps were studied. Each contained 1-6 cutaneous perforators originating from the profunda system, designated into A, B, or C vascular pedicle systems. Muscular perforators did not consistently extend to skin in systems A and C, but all dissections demonstrated myocutaneous perforator in system B. Average distance from groin crease to cutaneous perforators of A, B, and C respectively was 8 cm (range 3-15 cm), 11.4 cm (range 5-17 cm), and 17.5 cm (range 12.5-22 cm). Average pedicle length was 11.07 cm (range 7-16 cm), 11.78 cm (range 9-16 cm), and 11.23 cm (range 9-15 cm). Average vena comitans diameter at origin was 3.14 mm (range 1.27-4.46 mm). Average arterial diameter at origin was 2.07 mm (range 1.27-3.82 mm). Range of maximal primary closure was 6-11 cm. CONCLUSION: PAP free flap demonstrates reliable vascular anatomy in cadavers, with adequate pedicle length and vessel diameter. All specimens contained adequate myocutaneous perforator to support free tissue transfer.

The "bowtie" reconstruction flap: A unique solution to cervical esophageal discontinuity repair.

OBJECTIVES: Describe a novel technique for repair of cervical esophageal discontinuity. STUDY DESIGN: A 66-year-old female underwent hiatal hernia repair with a Nissen fundoplication. This was complicated by ischemic necrosis of the proximal stomach requiring urgent return to the operative suite for partial gastrectomy, esophageal diversion and subsequent esophagectomy repaired with a colonic interposition graft by Thoracic Surgery. This was further complicated by a cervical esophageal colonic anastomotic leak maturing to a cervical esophageal fistula and necessitating jejunostomy tube placement and consultation to Head and Neck Surgery. METHODS: Case report. RESULTS: In a team approach with Otolaryngology and Thoracic Surgery, she underwent a unique, multilevel repair with a salivary bypass stent bridging the gap between the proximal esophagus and distal colonic conduit. Bilateral local advancement flaps were elevated using the skin lateral to the fistula on each side with a random blood supply pedicled medially. Each flap was rotated medially over the stent and imbricated at midline. Next, a left myogenous pectoralis flap was raised and rotated over the site of imbrication. Lastly, a split thickness skin graft from the thigh was harvested and sutured over the pectoralis flap. Three months postoperatively, the salivary bypass stent was removed and by five months, the fistula was completely closed. With cervical esophageal dilations bimonthly, the patient has graduated to an oral diet without need of her jejunostomy tube for nearly four months. CONCLUSION: This case report describes a novel and efficacious solution to cervical esophageal discontinuity.

The practicality of a two-incision surgical approach for hypoglossal nerve stimulator implantation.

INTRODUCTION: Determine the feasibility of a two-incision surgical approach to hypoglossal nerve stimulator implantation based on anatomic considerations. METHODS: Upper airway stimulation (UAS) using the Inspire system uses three implanted devices-the implantable pulse generator (IPG), stimulation lead and sensing chest wall lead. The traditional surgical approach requires three skin incisions located on the submandibular neck, anterosuperior chest wall and inferolateral chest wall. Our surgical team sought to determine the anatomic considerations of combining the two chest wall incisions into one. In order to minimize morbidity and reduce operative time, the chest wall sensing lead was placed posterolateral to the IPG site via the same incision. RESULTS: Using an adult cadaver for anatomical analysis, access to the third and fourth intercostal spaces was made more difficult by the pectoralis major humeral head and upper arm. The intercostal space was narrower, the musculature along the anterior axillary line and anterior chest wall was devoid of the innermost intercostal muscle group found more laterally. Furthermore, there were much thinner external and internal intercostal muscle components as they transitioned to a membranous layer anteriorly in comparison to the inferolateral chest wall. CONCLUSION: Lack of the innermost intercostal muscle and thinning of the external and internal intercostal muscles lateral to the IPG site leaves little barrier between the thoracic musculature and parietal pleural increasing the risk of complications such as pleurisy and pneumothorax. Given the anatomical findings, a two-incision surgical approach for UAS therapy is at higher risk for complications.

Early discharge after free-tissue transfer does not increase adverse events.

INTRODUCTION: Demonstrate that carefully selected free flap patients may be discharged early after surgery without increasing the rates of postoperative complications or readmissions. METHODS: Based on a published article in Laryngoscope 2016 of 51 free-tissue transfers, a retrospective chart review was performed on an expanded cohort who underwent free-tissue transfer for head and neck reconstruction between February 2010 and May 2018 and discharged by postoperative day 3. RESULTS: 101 patients who underwent 104 free flaps with average age of 56 (3-84) years old were reviewed. Free flap indications included orbital and maxillary defects (n = 22), palatal defects (n = 16), nasal and septal defects (n = 16), cranioplasty and scalp defects (n = 16), mandibular defects due to osteoradionecrosis (n = 14), facial contouring and parotid defects (n = 12), and complex postsurgical and radiotherapy wounds or fistula closure (n = 8). Free flaps performed were anterolateral thigh (n = 97), radial forearm (n = 2), serratus (n = 2), latissimus (n = 1), fibula (n = 1) and supraclavicular (n = 1). The recipient vessels used via minimal access approaches were facial (n = 43), superficial temporal (n = 29), angular (n = 20) and others. There were 3 flap failures (2.9%) recognized in follow-up. No flap failures or perioperative complications were associated with early discharge. There were only 2 patients readmitted and 1 watched in observation within 30 days postoperatively. CONCLUSION: An updated review of our institutional experience with more than double the cohort size substantiates previous conclusions that early discharge after free-tissue transfer is a safe option in select patients. Moreover, earlier discharge is a critical management choice that reduces cost and decreases hospital-related adverse events.

Delayed laryngeal implant infection and laryngocutaneous fistula after medialization laryngoplasty.

BACKGROUND: Medialization laryngoplasty is a common procedure for voice rehabilitation in patients with unilateral vocal fold paralysis. Complications are uncommon and delayed infections involving implants are rare. We report a delayed infectious complication following an animal scratch resulting in a laryngocutaneous fistula. METHODS: Case report. RESULTS: A 73-year-old female underwent a successful and uneventful medialization laryngoplasty for idiopathic unilateral vocal fold paralysis using a silastic implant. More than one year after surgery, she presented with an anterior neck infection following an animal scratch with CT neck findings of a left strap muscle abscess. After incision and drainage, cultures grew methicillin-resistant Staphylococcus aureus. Despite culture-directed antibiotic therapy, the neck continued to drain persistently. Laryngoscopy with stroboscopy revealed a medialized vocal fold with no obvious granulation tissue and normal mucosal pliability. The patient underwent neck exploration revealing a laryngocutaneous fistula. Thus, both the fistulous tract and implant were removed. The wound was closed with a strap muscle advancement into the laryngoplasty window. One month after surgery and antibiotics, the patient had no signs of recurrent neck infection, with a well-healing wound and stroboscopic findings of complete glottic closure, symmetric vocal fold oscillation and acceptable phonation with mild supraglottic compression. CONCLUSIONS: Delayed complications of medialization laryngoplasty are rarely reported. This case demonstrates a delayed infection of a laryngeal implant after an animal scratch requiring implant removal, local tissue reconstruction, and culture-directed antibiotic therapy.

Spontaneous cervical chyle fistula: A case report.

BACKGROUND: Cervical chylous fistulae are rare complications usually occurring from iatrogenic injury to the thoracic duct. There have been no reported cases of spontaneous chyle leaks in surgical naïve necks. METHODS: Case report. RESULTS: A 50 year-old female presented with progressive left neck swelling without fever, dyspnea, or dysphagia. Imaging demonstrated extensive infiltrative changes of the left neck with retropharyngeal fluid extending into strap musculature and the mediastinum. Flexible laryngoscopy revealed posterior pharyngeal wall edema. Differential diagnosis included abscess versus necrotizing fasciitis. Broad-spectrum antibiotics were initiated and she was taken to the OR for neck exploration. Intra-operatively, milky fluid was present around the carotid sheath and in the retropharyngeal space. Fluid analysis demonstrated chylomicrons and triglycerides >2400 mg/dL. Repeat imaging of the neck, chest, and abdomen did not reveal malignancy or obstructive masses. A lymphangiogram showed dilated lymphatic vessels near the cervical thoracic duct. On post-operative day four, the patient was taken back to the OR for thoracic duct ligation and biopsy of nearby tissue. Pathology demonstrated benign lymph nodes with dilated sinusoids. A low-fat diet was started and she was discharged home on hospital day nine. She has followed up regularly with no signs of recurrence. CONCLUSION: A cervical chylous fistula usually results from iatrogenic injury to the thoracic duct. To our knowledge, this is the first reported case of a spontaneous cervical chyle leak.

Pyogenic granuloma of the larynx: A rare cause of hemoptysis.

Pyogenic granuloma (PG) may involve gingival mucosa (granuloma gravidarum) in pregnancy but rarely involves the airway. This case report is perhaps the only reported presentation of PG in the larynx causing hemoptysis at a late stage of pregnancy. On laryngoscopic exam, a vascular, right false vocal fold neoplasm was identified with pathological characteristics consistent with PG. Conclusions: Pyogenic granuloma is a relatively common tumor of pregnancy but rarely involves the larynx. In the case of airway involvement during pregnancy, it is best managed in coordination with the high-risk obstetrical team and can be removed safely via standard microsurgical techniques.

Post-treatment sequelae and management of primary laryngeal NK/T-cell lymphoma: A case report.

OUTCOME OBJECTIVES: METHODS: Case Report, April 2016. RESULTS: A 27-year-old female presented with a three-week history of flu-like symptoms including sore throat, myalgia and insidious nasal congestion. Her hospital course was complicated by pancytopenia, extensive GI bleed of unknown origin and fever. Radiographic studies revealed multifocal centrilobular ground-glass lung nodules, splenomegaly, frontal and paranasal sinus opacification and mucosal thickening and inflammatory process of false and true vocal cords with concentric multi-level narrowing. Extensive rheumatologic, hematologic and infectious workup failed to demonstrate an etiology. Flexible laryngoscopic and bronchoscopic examinations with biopsies exhibited a diffuse supraglottic and glottic exophytic, "heaped-up" infiltration; limited vocal cord motion; and airway narrowing to 3 mm. Pathology yielded NK/T-Cell lymphoma with PET/CT confirming nasopharyngeal and laryngeal involvement sparing the brain and other distant structures. During treatment, the patient's airway became increasingly compromised requiring tracheostomy. Flexible laryngoscopic examination after four rounds of SMILE (dexamethasone, methotrexate, ifosfamide, l-asparaginase, and etoposide) chemotherapy and subsequent radiotherapy with 50 Gy in 25 fractions revealed complete glottic stenosis with alteration of the laryngeal anatomy and a pin-hole aperture seen posteriorly through the tracheostomy. Two dilation procedures performed one month apart, improved her airway considerably which allowed for successful decannulation. She continues to be disease-free post treatment but has persistent supraglottic and glottic scar and has developed tracheal stenosis at her tracheostomal site. CONCLUSIONS: NK/T-Cell lymphoma of the larynx has been rarely described. Herein, we describe the sequalae of treatment and the requisite airway management.

Rhabdomyosarcoma Arising in an Old Rhytidectomy Scar.

OBJECTIVE: The clinical evaluation and management of an adult with head and neck rhabdomyosarcoma is explored to delineate the diagnostic challenge posed by soft-tissue sarcomas bordering scar tissue. CASE REPORT: A 59 year old female presents with persistent, evolving paresthesia and burning in the right posterior neck, which was found to be in close proximity to a well-healed rhytidectomy scar. Serial biopsies were non-diagnostic. Six months after initial presentation, rhabdomyosarcoma was diagnosed subsequent to histopathological and immunohistochemistry analysis. A wide local excision with posterolateral neck dissection was performed. CONCLUSION: A high index of suspicion for soft-tissue sarcoma should be maintained for patients with persistent soft-tissue lesions, especially in areas of scarred tissue, who present with new-onset neurological symptoms in the context of nondiagnostic biopsies.

Evaluation of Anterolateral Thigh Fascia Lata Rescue Flap for Mandibular Osteoradionecrosis.

Importance: Mandibular osteoradionecrosis (ORN) is a progressive disease that can be difficult to treat. Conservative measures often fail, while conventional definitive management requires a morbid segmental resection with osteocutaneous reconstruction. Evidence of the anterolateral thigh fascia lata (ALTFL) rescue flap technique's safety, effectiveness, and long-term outcomes is needed. Objective: To determine the long-term outcomes of the ALTFL rescue flap procedure for treating patients with mandibular ORN. Design, Settings, and Participants: This was a retrospective medical record review performed at a single tertiary-level academic health care institution with patients who were appropriate candidates for the ALTFL procedure to treat mandibular ORN from March 3, 2011, to December 31, 2022. Data analyses were performed from January 1 to March 26, 2023. Main Outcomes and Measures: Patient characteristics, preoperative radiographic Notani staging, intraoperative defect size, length of stay, complication rates, and clinical and radiographic findings of progression-free intervals. Results: The study population of 43 patients (mean [SD] age, 66.1 [47-80] years; 24 [55.8%] male individuals) included 52 cases of mandibular ORN. The preoperative Notani staging of the study population was known for 46 of the 52 total cases: 11 cases (23.9%) were stage I; 21 (45.7%), stage II; and 14 (30.4%), stage III. The mean defect area was 20.9 cm2. Successful arrest of ORN disease progression was noted in the clinical and radiographic findings of 50 of the 52 (96.2%) cases, with only 2 (3.8%) cases subsequently requiring fibular free flap reconstruction. The major complication rate was 1.9% (1 case). Clinical and radiographic progression-free intervals were assessed, and no statistically significant differences were noted between Notani staging groups (log-rank P = .43 and P = .43, respectively); ie, patients with stage III disease had no significant difference in risk of clinical (HR, 0.866; 95% CI, 0.054-13.853) or radiographic (HR, 0.959; 95% CI, 0.059-15.474) progression vs those with stage I disease. Weibull profiling revealed 96.9%, 94.6%, and 93.1% successful mandibular ORN arrest at 1, 3, and 5 years, respectively. The major complication rate was 1.9%. Mean (SD) length of stay was 2.7 (0.0-7.0) days. Mean (SD) radiographic follow-up was 29.3 (30.7) months. Conclusions and Relevance: The findings of this large retrospective patient case series support the continued success of the ALTFL rescue flap technique, a safe and highly effective long-term treatment for mandibular ORN in carefully selected patients.

Cost-Effectiveness of Open vs. Endoscopic Repair of Zenker's Diverticulum.

OBJECTIVE: To evaluate the cost-effectiveness of open versus endoscopic surgical repair of Zenker's diverticulum. METHODS: In this study, an economic decision tree was utilized to compare the cost-effectiveness of open surgery compared to endoscopic surgery. The primary outcome in this analysis was the incremental cost-effectiveness ratio (ICER) that was calculated based on the economic decision tree. The probability of post-operative esophageal perforation complications, revision rates, and effectiveness of each procedure along with associated costs were extracted to construct the decision tree. Univariate sensitivity analysis was then utilized to determine how changes in esophageal perforation rate affect the cost-effectiveness of each surgical approach. RESULTS: The ICER of open surgery for Zenker's diverticulum was $67 877, above most acceptable willingness to pay (WTP) thresholds. Additionally, if the probability of esophageal perforation with endoscopic surgery is above 5%, then open surgery becomes a more cost-effective option. Probabilistic sensitivity analysis using Monte Carlo simulations also showed that at the WTP thresholds of $30 000 and $50 000, endoscopic surgery is the most cost-effective method with 83.9% and 67.6% certainty, respectively. CONCLUSION: Open surgery and endoscopic surgery are 2 treatment strategies for Zenker's diverticulum that each have their own advantages and disadvantages that can complicate the decision-making process. With no previous cost-effectiveness analysis of open versus endoscopic surgery for Zenker's diverticulum, our results support the endoscopic approach at most common WTP thresholds. Particularly with the current focus on rising healthcare costs, our results can serve as an important adjunct to medical decision-making for patients undergoing treatment for Zenker's diverticulum.

Anterolateral Thigh Fascia Lata Rescue Flap: A New Weapon in the Battle Against Osteoradionecrosis.

OBJECTIVES: To demonstrate that the anterolateral thigh fascia lata (ALTFL) rescue flap may be effectively used for management of osteoradionecrosis (ORN) in selected patients. STUDY DESIGN: Retrospective case review. METHODS: Retrospective chart review was performed on patients who underwent ALTFL free flap repair to various sites of ORN in the head and neck between 2011 and 2018. Inclusion criteria were patients with radiographic and clinical evidence of head and neck ORN who either failed previous hyperbaric oxygen (HBO) therapy or with extensive disease, which was unlikely to respond to conservative management. RESULTS: Twenty-three patients with average age of 63 years (40-78) who underwent 24 ALTFL free flap procedures were reviewed. ORN sites were the mandible (n = 16), palatomaxilla (n = 4), skull base and cervical spine (n = 3), and calvarium (n = 2). Recipient vessels used were superficial temporal (n = 11), common facial (n = 10), and angular (n = 3). Average hospital stay was 3.0 (1-10) days. Prior HBO therapy was performed in 13 (57%) patients. There were four major complications: flap failure, recurrent mandibular infection resolved with IV antibiotic course, mandibular fracture with malunion requiring occlusal adjustment, and unresolved sequelae of ORN requiring fibular free flap. There were four minor complications: thigh hematoma, thigh seroma, and intraoral scar formation causing trismus (n = 2). The procedure was successful in 22 of 23 (95.7%) patients with radiographic arrest of ORN, resolution of symptoms, and elimination of antibiotic requirements. CONCLUSION: The ALTFL rescue flap merits strong consideration in ORN management and appears to prevent progression to more extensive disease, which would require full segmental bone resection and reconstruction.

Reconfiguration of Upper Airway Stimulation Devices Utilizing Awake Endoscopy.

OBJECTIVES: Determine the rates of, reasons for, and effectiveness of device reprogramming utilizing in-office awake endoscopy (AE) in subjects who underwent upper airway stimulation (UAS) surgery. STUDY DESIGN: Retrospective chart review. METHODS: Retrospective chart review at a tertiary care center on patients implanted with UAS devices from November 2015 to July 2018. RESULTS: Sixty patients were implanted with UAS devices. Average pre- and postsurgical total apnea-hypopnea index (AHI) was 40.6 and 4.2 with a 36.4 total AHI reduction. Treatment success based on Sher criteria was observed in 88% of patients. Postoperative titration polysomnography revealed an average functional threshold (FT) and minimum therapeutic amplitude (MTA) of 1.6 and 2.1 V, respectively. A total of 24 AEs were performed in 19 (32%) patients. The most common complaints and reasons for AE were perceived stimulus discomfort (42%), frequent awakenings (32%), and persistent fatigue or non-normalized AHI (21%). After first AE, there was a 0.87 (53%) and 0.93 (45%) V reduction in FT and MTA, respectively. CONCLUSION: Patients with obstructive sleep apnea continue to succeed with UAS. Fewer than one-third of patients had postsurgical complaints requiring device reconfiguration utilizing AE to assess the pharyngeal airway and optimize device settings. Reduction in the FT and MTA after AE may improve compliance by reducing discomfort and frequent awakenings. Periodic monitoring of patients with implanted UAS devices is necessary to optimize efficacy and maintain patient compliance. LEVEL OF EVIDENCE: 4 Laryngoscope, 130:2494-2498, 2020.

Outcomes of audiometric testing in children with auditory neuropathy spectrum disorder.

INTRODUCTION: Auditory Neuropathy Spectrum Disorder (ANSD) is characterized by hearing loss ranging from normal to profound. Additionally, results are confounded by commonly fluctuating hearing thresholds in ANSD. As such, we sought to evaluate results of audiometric testing on children with ANSD and the impact of age and time on testing results. METHODS: Retrospective chart review on children <18 years of age diagnosed with ANSD at two tertiary care academic institutions. Data analyzed included initial audiogram with speech detection thresholds (SDT) and pure tone averages (PTA) as well as most recent unaided audiogram SDT and PTA. RESULTS: 75 ANSD patients were analyzed, of which 32 (42.7%) were female. Bilateral and unilateral ANSD was seen in 55 (73.3%) and 20 (26.7%), respectively. A total of 130 ears with ANSD were assessed with 80 (61.5%) meeting inclusion criteria. Of these patients, the median age in years at first audiogram and most recent audiogram were 1.94 (0.45-13.68) and 4.22 (0.97-14.61), respectively. The median ages at which an SDT and PTA could first be acquired on the audiogram in ANSD patients were 1.94 (0.50-13.68) and 2.86 (0.45-13.68), respectively. The average SDT/PTA at the initial and most recent audiogram were 47.5/45.7 and 49.4/53.0 dB, respectively. SDT to PTA within the same audiogram exhibited strong correlation (r = 0.82, p < 0.001). Similarly, comparison of initial SDT to SDT at a later time interval showed strong correlation (r = 0.73, p < 0.001). SDT and PTA at initial audiogram and PTA at later time demonstrated lower correlation but was still statistically significant (r = 0.49, p < 0.009 and r = 0.51, p < 0.044, respectively). Individual PTA was associated with age (r = -0.56, p < 0.001). CONCLUSIONS: SDT and PTA within the same audiogram and initial SDT to SDT acquired at a later time correlate strongly in audiometric testing in children with ANSD. Although not as strong, initial SDT and PTA still correlate with PTA at a later time interval. These findings suggest that audiometric results yielding a reliable SDT and frequency specific information necessary to calculate the PTA is not typically obtained until 2-3 years old. However, once this information is obtained, the child's hearing is fairly stable but may fluctuate over time.

Reducing the need for general anesthesia in the repair of choanal atresia with steroid-eluting stents: A case series.

INTRODUCTION: Choanal atresia (CA) is a rare pediatric congenital disorder resulting in upper airway obstruction and respiratory distress in the setting of obligate nasal breathing in infants. In 2016, a novel technique was reported in the literature utilizing drug-eluting stents to correct CA. However, 2 out of 3 patients in the study required a second operation under general anesthesia. The repeated visits to the operating room for evaluations and debridement under general anesthesia continues to be a concern for increased morbidity and mortality in infants undergoing repair of CA. METHODS: A case series of three (3) patients who underwent repair of CA. Outcomes were measured by post-operative, in-office flexible nasoendoscopy. RESULTS: Each patient was implanted with mometasone furoate drug-eluting stents at the conclusion of the operation. Post-operatively, patients were instructed to perform nasal saline rinses 3-4 times daily. Outpatient follow-up between 6 and 17 months showed patent nasal passages on nasal endoscopy. There were no post-operative complications. Moreover, patients only underwent a single episode of general anesthesia at time of initial repair. CONCLUSIONS: In our study, we report successful outcomes using drugeluting stents for one-stage surgical correction of CA, therefore negating the need for children to undergo multiple subjections to general anesthetics.

Natural history of silent aspiration on modified barium swallow studies in the pediatric population.

OBJECTIVES: To investigate the natural history of silent aspiration in the pediatric population. METHODS: Retrospective chart review of patients (age < 3 years) who underwent modified barium swallow studies (MBSS), between January 1, 2007, to December 31, 2017, were studied to compare comorbidities and determine course of resolution in those with silent aspiration. RESULTS: A total of 148 charts were reviewed. Patients that underwent surgical intervention for laryngeal anomalies causing silent aspiration and those with overt aspiration or oral aversion were excluded. Of the 56 patients in the study, 25 had silent aspiration and 31 demonstrated no silent aspiration on MBSS. There was a higher rate of overall comorbidities amongst silent aspirators (96.0% vs. 48.4%, p=0.003) in comparison to patients with no silent aspiration on MBSS. Silent aspirators had higher rates of cerebral palsy (16.0% vs. 0%, p=0.034), and seizures (36.0% vs. 3.2%, p=0.003). Of the 20 patients with silent aspiration with an MBSS completed beyond the initial one, 13 (65.0%) experienced resolution, 5 (20.0%) did not experience resolution by age 5, and 2 (10.0%) had unknown resolution due to being lost to follow up or not yet reaching age 5. No statistically significant associations were found between comorbidities, gender, presence of a gastrostomy tube and resolution. CONCLUSIONS: Silent aspiration in children is associated with neurological comorbidities, particularly cerebral palsy and seizures. More than half of the patients with silent aspiration spontaneously resolve over time. Expectant management, close surveillance, and clinical assessments can be considered in these patients on an individual basis.

Metastasis of Ewing's sarcoma to the thyroid gland: A case report.

Ewing's sarcoma (ES) is an aggressive pediatric malignancy. We present a case of ES with thyroid metastasis. The patient was diagnosed with ES at age 8. Despite aggressive treatment, she suffered disease progression. Surveillance demonstrated a left thyroid lesion. This grew rapidly within 2 months, causing tracheal compression. She underwent hemi-thyroidectomy to prevent airway compromise. Due to her refractory ES, she was enrolled in the Vigil immunotherapy vaccine trial; thus, the specimen was used for vaccine development. This is the first reported case of skeletal ES with metastasis to the thyroid, requiring hemithyroidectomy to prevent airway compromise.
