In vitro comparison of surgical techniques in times of the SARS-CoV-2 pandemic: electrocautery generates more droplets and aerosol than laser surgery or drilling.

INTRODUCTION: Based on current knowledge, the SARS-CoV-2 is transmitted via droplet, aerosols and smear infection. Due to a confirmed high virus load in the upper respiratory tract of COVID-19 patients, there is a potential risk of infection for health care professionals when performing surgical procedures in this area. The aim of this study was the semi-quantitative comparison of ENT-typical interventions in the head and neck area with regard to particle and aerosol generation. These data can potentially contribute to a better risk assessment of aerogenic SARS-CoV-2-transmission caused by medical procedures. MATERIALS AND METHODS: As a model, a test chamber was created to examine various typical surgical interventions on porcine soft and hard tissues. Simultaneously, particle and aerosol release were recorded and semi-quantitatively evaluated time-dependently. Five typical surgical intervention techniques (mechanical stress with a passive instrument with and without suction, CO2 laser treatment, drilling and bipolar electrocoagulation) were examined and compared regarding resulting particle release. RESULTS: Neither aerosols nor particles could be detected during mechanical manipulation with and without suction. The use of laser technique showed considerable formation of aerosol. During drilling, mainly solid tissue particles were scattered into the environment (18.2 ± 15.7 particles/cm2/min). The strongest particle release was determined during electrocoagulation (77.2 ± 30.4 particles/cm2/min). The difference in particle release between electrocoagulation and drilling was significant (p < 0.05), while particle diameter was comparable. In addition, relevant amounts of aerosol were released during electrocoagulation (79.6% of the maximum flue gas emission during laser treatment). DISCUSSION: Our results demonstrated clear differences comparing surgical model interventions. In contrast to sole mechanical stress with passive instruments, all active instruments (laser, drilling and electrocoagulation) released particles and aerosols. Assuming that particle and aerosol exposure is clinically correlated to the risk of SARS-CoV-2-transmission from the patient to the physician, a potential risk for health care professionals for infection cannot be excluded. Especially electrocautery is frequently used for emergency treatment, e.g., nose bleeding. The use of this technique may, therefore, be considered particularly critical in potentially infectious patients. Alternative methods may be given preference and personal protective equipment should be used consequently.

Reducing the risks of endoscopic sinonasal surgery in the Covid-19 era.

OBJECTIVES: Many routine sinonasal procedures utilising powered instruments are regarded as aerosol-generating. This study aimed to assess how different instrument settings affect detectable droplet spread and patterns of aerosolised droplet spread during simulated sinonasal surgery in order to identify mitigation strategies. DESIGN: Simulation series using three-dimensional (3-D) printed sinonasal model. Fluorescein droplet spread was assessed following microdebriding and drilling of fluorescein-soaked grapes and bones, respectively. SETTING: University dry lab. PARTICIPANTS: 3-D printed sinonasal model. MAIN OUTCOME MEASURES: Patterns of aerosolised droplet spread. RESULTS AND CONCLUSION: There were no observed fluorescein droplets or splatter in the measured surgical field after microdebridement of nasal polyps at aspecific irrigation rate and suction pressure. Activation of the microdebrider in the presence of excess fluid in the nasal cavity (reduced or blocked suction pressure, excessive irrigation fluid or bleeding) resulted in detectable droplet spread. Drilling with either coarse diamond or cutting burs resulted in detectable droplets and greater spread was observed when drilling within the anterior nasal cavity. High-speed drilling is a high-risk AGP but the addition of suction using a third hand technique reduces detectable droplet spread outside the nasal cavity. Using the instrument outside the nasal cavity inadvertently, or when unblocking, produces greater droplet spread and requires more caution.

COVID-19 in otolaryngologist practice: a review of current knowledge.

PURPOSE: Otorhinolaryngological manifestations are common symptoms of COVID-19. This study provides a brief and precise review of the current knowledge regarding COVID-19, including disease transmission, clinical characteristics, diagnosis, and potential treatment. The article focused on COVID-19-related information useful in otolaryngologist practice. METHODS: The Medline and Web of Science databases were searched without a time limit using terms "COVID-19", "SARS-CoV-2" in conjunction with "otorhinolaryngological manifestation", "ENT", and "olfaction". RESULTS: The most common otolaryngological dysfunctions of COVID-19 were cough, sore throat, and dyspnea. Rhinorrhea, nasal congestion and dizziness were also present. COVID-19 could manifest as an isolated sudden hyposmia/anosmia. Upper respiratory tract (URT) symptoms were commonly observed in younger patients and usually appeared initially. They could be present even before the molecular confirmation of SARS-CoV-2. Otolaryngologists are of great risk of becoming infected with SARS-CoV-2 as they cope with URT. ENT surgeons could be easily infected by SARS-CoV-2 during performing surgery in COVID-19 patients. CONCLUSION: Ear, nose and throat (ENT) symptoms may precede the development of severe COVID-19. During COVID-19 pandemic, patients with cough, sore throat, dyspnea, hyposmia/anosmia and a history of travel to the region with confirmed COVID-19 patients, should be considered as potential COVID-19 cases. An otolaryngologist should wear FFP3/N95 mask, glasses, disposable and fluid resistant gloves and gown while examining such individuals. Not urgent ENT surgeries should be postponed. Additional studies analyzing why some patients develop ENT symptoms during COVID-19 and others do not are needed. Further research is needed to determine the mechanism leading to anosmia.

Functional sparing surgery policy for giant vestibular schwannomas.

OBJECTIVE: The objective of this study was to compare the tumour control and facial nerve outcome according to the therapeutic strategy, that is extent of resection and post-operative radiotherapy. DESIGN: Retrospective study of patients with a giant vestibular schwannoma surgically treated from 4 academic skull base centres. SETTING: Extent of resection, neurological complications, facial nerve function, MRI follow-up and occurrence of complementary treatment were reviewed. PARTICIPANTS: Sixty patients were included from 2000 to 2018. MAIN OUTCOME MEASURES: Primary end points were comparison the tumour control rate and the post-operative House-Brackmann grade at last follow-up according to the extent of tumour removal (ie total or subtotal removal). Secondary end points were assessment risk factors of poor facial nerve function and comparison complication rate according to extent of tumour removal. RESULTS: Sixty patients had initial surgery at diagnosis. A total resection was realised in 21 cases and a subtotal resection in 39 cases. Thirteen patients needed further treatment. One patient had a recurrence and needed a second surgery 108 months after the initial total resection surgery. Twelve patients underwent post-operative radiotherapy, for an evolutive residual tumour. Tumour control was more successful in the total resection group (log-rank test, P = .015). There was no tumour recurrence after post-operative radiotherapy. The facial nerve outcome was significantly better in the subtotal resection group (Mean House-Brackmann grade at last follow-up: 2.2 ± 1.9) than in the total resection group (House-Brackmann grade: 3.5 ± 2.2) (P = .033). Vestibular schwannoma with a cystic component had better facial nerve outcome (P = .0082). Other than facial paralysis, neurological complications were observed in six patients (10% of patients): lower cranial nerves dysfunction in five cases and hemiparesis in one case. CONCLUSIONS: Subtotal resection of giant vestibular schwannomas leads to favourable tumour control and facial nerve function and therefore seems to be a valuable strategy.

COVID-19: An otolaryngological perspective.

Otolaryngologists around the world are amongst the front-line fighters against the pandemic coronavirus disease (COVID-19). As knowledge about the disease epidemiology and clinical profile is rapidly evolving, we are still not sure about many different aspects of the disease transmission and presentation. Otolaryngologists regularly deal with the upper aerodigestive tract, which is the portal of transmission and site of multiplication of the virus. There is a substantial risk of getting infected and transmitting the disease further. We discuss the various recommendations pertaining to the emergency and elective procedures in otolaryngology, and head and neck surgeries in these difficult times, so as to sensitise the clinicians while dealing with such cases, till the pandemic is under control and things get back to normal.

[S2e-guideline: "ENT-specific therapy of obstructive sleep apnea in adults" short version : Sleep Medicine Task Force of the German Society for Otorhinolaryngology, Head and Neck Surgery]. / Leitlinie: "HNO-spezifische Therapie der obstruktiven Schlafapnoe bei Erwachsenen" Kurzfassung : ArGe Schlafmedizin der Deutschen Gesellschaft für Hals-Nasen-Ohren-Heilkunde, Kopf- und Hals-Chirurgie.

[Intraoperative quality management modalities in head and neck surgery]. / Intraoperative Modalitäten zur Qualitätssicherung in der Kopf­Hals­Chirurgie.

Immediate intraoperative control via suitable imaging techniques is necessary to achieve the best possible surgical outcome. Intraoperative imaging increases patient safety, offers the surgeon direct support in challenging anatomic regions, and affords the possibility of direct correction with a reduced rate of corrective surgery. The procedures are based on cone beam computed tomography (CBCT), endoscopy, or navigation-assisted surgery. This article describes available intraoperative quality management modalities for fracture management and tumor treatment in the field of head and neck surgery.

A prospective study of blood splatter in ENT.

Surgeons face an occupational risk of daily exposure to blood and body fluids. Potential sources of infection include sharps injuries and mucocutaneous contact. The transmission of blood-borne viruses, in particular human immunodeficiency virus (HIV), Hepatitis B and Hepatitis C from the patient to healthcare workers is well documented in the literature. We studied the incidence and degree of blood splash in all otolaryngology (ENT) procedures undertaken in a single unit over a 12 week period. In addition, we investigated which intraoperative factors might predict the degree of splash. We undertook a prospective, non-blinded study of 102 patients undergoing a range of 'routine' elective ENT within one department over 12 weeks. A surgical mask with visor attached was worn in all procedures. Following each procedure, all splatter masks were collected and examined macroscopically and microscopically for blood splash. In addition, the procedure performed, technique used, total blood loss, operating time and grade of surgeon was noted. 54% of procedures resulted in splash mask contamination. The median number of splash spots per mask was 4.7 (range 0-63). Tonsillectomy was the most commonly performed procedure, accounting for over one-third of total procedures investigated. Each mask had an average of 8.2 splash marks. Tonsillectomy had a splash rate of 76.9%. Although the risk of developing HIV is low the operating surgeon has a duty to take all precautions to protect themselves during a procedure and therefore a protective mask and visor or suitable goggles must be worn.

[Perioperative antibiotic prophylaxis during standard interventions in ear, nose and throat medicine]. / Perioperative Antibiotikaprophylaxe bei Standardeingriffen in der HNO-Heilkunde.

BACKGROUND: The majority of standard interventions in otorhinolaryngology are classified as "clean contaminated" according to international classifications; correspondingly, no generally accepted recommendations regarding perioperative antibiotic prophylaxis (pAP) exist. The value of such pAP for these interventions remains unclear. Aim of the study was to assess the effects of pAP in selected standard otorhinolaryngologic procedures. MATERIALS AND METHODS: In August 2012 a standard operating procedure (SOP) was implemented, which lead to termination of routine pAP for the majority of standard operations. All patients included in this retrospective study had undergone a standard procedure (tonsil, septum or paranasal sinus surgery) during a period either 6 months before or 6 months after the inauguration of the SOP. The charts were reviewed for demographic factors, postoperative complications and length of hospital stay. RESULTS: The group before the inauguration of the SOP consisted of 316 patients (132 female, 184 male), aged 30±20 years. The group after the inauguration comprised 308 patients (128 female, 180 male), aged 31±19 years. For the entire patient collective, the termination of pAP led to a statistically significant increase in postoperative antibiotic treatment for all types of interventions tested. A statistically significant change in noninflammatory complications or the length of hospital stay was not detected. DISCUSSION: The termination of pAP during standard procedures in otorhinolaryngology is associated with an increase in postoperative antibiotic treatment but has no effect on other postoperative complications tested or the length of hospital stay.

[The modern strategy for the treatment of the patients presenting with odontogenic maxillary sinusitis and the oroantral fistula].

The objective of the present study was the comparative analysis of various methods for the plastic correction of the oroantral fistula with the use of the mucosal flap and the osteoplastic materials based on the data from the literature and on-line publkations. The characteristics of an ideal material for the plastic correction ot the oroantral fistula and the conditions for carrying out this surgery are discussed.

Venous thromboembolism in ENT surgery: a review of the literature and completed audit cycle of adherence to national guidance.

Venous thromboembolism (VTE) risk assessment of elective ENT patients is essential to minimize the risk of mortality and morbidity. The study is standard-based audit of VTE risk assessment against the ENT UK guidelines and intervention includes instructional poster and departmental presentation. 23 patients on eight operating lists were audited in the first cycle (C1). A total of 27 patients on ten operating lists were re-audited in the second cycle (C2). There were marked improvements in the number of VTE risk assessments completed (C1 = 3/23; C2 = 26/27; p < 0.0001), the number of patients encouraged to mobilize (C1 = 0/23; C2 = 26/27; p < 0.0001), and the number of VTE leaflets provided upon discharge (C1 = 1/23; C2 = 27/27; p < 0.0001) following the intervention. The introduction of a poster and a departmental presentation proved to be simple, cheap, and effective measures to improve adherence of national VTE guidelines.

ENT one day surgery: critical analysis with the HFMEA method.

OBJECTIVES: Research shows that 51.4% of adverse events in hospitals occur in surgery and that 3-22% of surgical patients experience adverse events. The risk may be even higher when turnover is high and when patients are children, as is often the case in ear, nose and throat surgery. This quality project therefore started in response to requests from physicians in two hospitals in the Flemish part of Belgium. The aim of this study is to use the Healthcare Failure Mode & Effect Analysis method to evaluate the process flow for ear, nose and throat patients, and to redesign the process to enhance patient safety. METHODOLOGY: In two One Day Clinics, processes were prospectively analysed using the Healthcare Failure Mode & Effect Analysis method. RESULTS: Similar potential failures were reported in both hospitals. The major failure mode was linked to the absence of an active identity check throughout the process. The process was therefore redesigned by implementing a surgical safety checklist and an active identity check protocol. Although the Healthcare Failure Mode & Effect Analysis is a time-consuming method, this systematic approach by a multidisciplinary team has been found to be useful in detecting failure modes that need immediate safety responses. The involvement of all disciplines and an open safety culture during the procedure were the most important conditions. CONCLUSIONS: The Healthcare Failure Mode & Effect Analysis is a useful instrument for detecting the failure modes in this care process.

Critical Review and Consensus Statement for Neural Monitoring in Otolaryngologic Head, Neck, and Endocrine Surgery.

BACKGROUND: Enhancing patient outcomes in an array of surgical procedures in the head and neck requires the maintenance of complex regional functions through the protection of cranial nerve integrity. This review and consensus statement cover the scope of cranial nerve monitoring of all cranial nerves that are of practical importance in head, neck, and endocrine surgery except for cranial nerves VII and VIII within the temporal bone. Complete and applied understanding of neurophysiologic principles facilitates the surgeon's ability to monitor the at-risk nerve. METHODS: The American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) identified the need for a consensus statement on cranial nerve monitoring. An AAO-HNS task force was created through soliciting experts on the subject. Relevant domains were identified, including residency education, neurophysiology, application, and various techniques for monitoring pertinent cranial nerves. A document was generated to incorporate and consolidate these domains. The panel used a modified Delphi method for consensus generation. RESULTS: Consensus was achieved in the domains of education needs and anesthesia considerations, as well as setup, troubleshooting, and documentation. Specific cranial nerve monitoring was evaluated and reached consensus for all cranial nerves in statement 4 with the exception of the spinal accessory nerve. Although the spinal accessory nerve's value can never be marginalized, the task force did not feel that the existing literature was as robust to support a recommendation of routine monitoring of this nerve. In contrast, there is robust supporting literature cited and consensus for routine monitoring in certain procedures, such as thyroid surgery, to optimize patient outcomes. CONCLUSIONS: The AAO-HNS Cranial Nerve Monitoring Task Force has provided a state-of-the-art review in neural monitoring in otolaryngologic head, neck, and endocrine surgery. The evidence-based review was complemented by consensus statements utilizing a modified Delphi method to prioritize key statements to enhance patient outcomes in an array of surgical procedures in the head and neck. A precise definition of what actually constitutes intraoperative nerve monitoring and its benefits have been provided.

Benchmarks for the durations of ambulatory surgical procedures in otolaryngology.

OBJECTIVES: I undertook to determine benchmarks and variability for the surgical times associated with ambulatory otolaryngological procedures in the United States. METHODS: I examined the 2006 release of the National Survey of Ambulatory Surgery and extracted all cases of otolaryngological surgery in which one, and only one, otolaryngological procedure was performed. The mean surgical times and operating room times were determined for each procedure that met reliability criteria for their estimates. A secondary analysis was computed for tonsillectomy and for tonsillectomy plus adenoidectomy according to a patient age of greater than 12 years. RESULTS: An estimated 1.68 +/- 0.23 million otolaryngological procedures were analyzed as solitary procedures, including 507,000 cases of myringotomy with ventilation tube placement, 136,000 cases of tonsillectomy, and 429,000 cases of tonsillectomy plus adenoidectomy. The mean (+/- SE) surgical times were 8.0 +/- 0.5, 23.9 +/- 1.8, and 20.3 +/- 0.8 minutes, respectively. The total operating room times were 17.6 +/- 0.9, 48.2 +/- 2.0, and 40.7 +/- 1.1 minutes, respectively. Septoplasty with turbinectomy was the most common rhinologic procedure performed (48,000 cases analyzed) and had surgical and operating room times of 49.6 +/- 4.78 and 79.8 +/- 5.8 minutes, respectively. The surgical times for tonsillectomy and tonsillectomy plus adenoidectomy did not differ significantly in magnitude according to standard age cutoffs, although the operating room time was slightly (11.7 minutes) longer for tonsillectomy in patients more than 12 years of age (p = 0.034). CONCLUSIONS: The surgical times for the performance of the most common otolaryngological ambulatory procedures are remarkably consistent in the United States. Given the volume and consistency of these surgical procedures, they are ideal candidates for studies of cost and efficiency.

Achieving consensus in follow-up practice for routine ENT procedures: a Delphi exercise.

OBJECTIVES: To generate consensus amongst faculty members regarding follow-up practice for well-defined clinical scenarios using a Delphi exercise and to identify whether disseminating the consensus guidelines changed follow-up practice. STUDY DESIGN: Generation of consensus using a Delphi exercise and an audit of follow-up practice before and after dissemination of the resultant guidelines. SETTING: The department of Otorhinolaryngology-Head and Neck Surgery at the Freeman Hospital, Newcastle upon Tyne, UK. PARTICIPANTS AND METHODS: Panel members for this exercise included 11 consultants and two associate specialists and one co-ordinator. We identified clinical scenarios where ≥ 80% agreement existed that routine follow-up appointments should not be made and subsequently disseminated guidelines widely to all medical staff. The follow-up rates for the scenarios where consensus existed regarding follow-up practice were audited from clinic letters before and after the guidelines were disseminated. MAIN OUTCOME MEASURES: Agreement on scenarios where routine follow-up appointments should not be made was assessed using a Likert scale (1-5). RESULTS: Of 13 faculty members, 12 responded to rounds one and two, and 11 responded to round three. The Delphi exercise identified 18 clinical scenarios where there was ≥ 80% agreement on patients not routinely being followed up. Comparison of the follow-up practice prior to and after the Delphi exercise identified a reduction in follow-up for all 18 scenarios of 48%. CONCLUSION: Consensus regarding routine follow-up can be reached by using the Delphi process in ENT practice. This can translate into a real change in clinical practice. Furthermore, this process could be applied for consensus building in other related areas.

Towards better patient safety: WHO Surgical Safety Checklist in otorhinolaryngology.

OBJECTIVES: The World Health Organisation has developed a Surgical Safety Checklist to improve patient safety during surgery. This checklist has reduced postoperative morbidity and mortality. Prior to checklist implementation, we wanted to evaluate how it would fit into the process of otorhinolaryngology-head and neck surgery and whether it would have an impact on the awareness of safety-related issues. DESIGN: A structured questionnaire was addressed to the operating room team after consecutive operations during a 1-month period before and after checklist implementation. SETTING AND PARTICIPANTS: This study was conducted at the Department of Otorhinolaryngology at the Helsinki University Central Hospital as a part of a multicentre study. Responses were received regarding 288 operations before and 412 after checklist implementation. MAIN OUTCOME MEASURES: The questions concerned patient-related safety checks, teamwork and communication. RESULTS: The checklist improved verification of the patient's identity (P<0.001). Awareness of the patient's medical history, medication and allergies increased (P<0.001). Knowledge of the names and roles among the team members improved. The otolaryngologists and anaesthesiologists discussed possible critical events more often (P<0.001), and postoperative instructions were better recorded after use of the checklist. In addition, the checklist enhanced communication between operation team members. CONCLUSIONS: Our study confirms that the Surgical Safety Checklist fits well into the surgical working process in otorhinolaryngology-head and neck surgery improving the sharing of patient-related medical information between team members. Development of a specific checklist for otolaryngology calls for further study.

Clinical Excellence in Otolaryngology-Head and Neck Surgery: Examples from the Published Literature.

OBJECTIVE/HYPOTHESIS: To apply the domains of clinical excellence, as published by the Miller-Coulson Academy of Clinical Excellence, to the field of otolaryngology-head and neck surgery (OHNS) as a framework for evaluating and improving clinical excellence. METHODS: A search of PubMed, Scopus, the Cochrane Library, and the National Institute for Health and Care Excellence (NICE) databases was performed and 229 publications were reviewed. RESULTS: Case reports and other articles were selected that exemplify each of the distinct domains of clinical excellence within our specialty. CONCLUSIONS: The Miller-Coulson Academy's domains of clinical excellence are relevant to OHNS and can provide a framework for fostering clinical excellence in otolaryngologists. The many examples of excellent care by otolaryngologists found in the published literature can inspire otolaryngologists to provide outstanding care to all patients consistently and to advance our specialty.

YO-IFOS Guidelines for Pediatric ENT Surgery during COVID-19: An Overview of Recommendations.

OBJECTIVE/HYPOTHESIS: To review the literature on pediatric ENT COVID-19 guidelines worldwide, in particular, surgical practice during the pandemic, and to establish a comprehensive set of recommendations. STUDY DESIGN: Review. METHODS: A comprehensive literature review through an independent electronic search of the COVID-19 pandemic in PubMed, Medline, Google, and Google Scholar was performed on April 26-30, 2020. Resources identified comprised of published papers, national and international pediatric ENT society guidelines. RESULTS: Fourteen guidelines fit the inclusion criteria. Key statements were formulated and graded: 1) Strong recommendation (reported by 9 or more/14); 2) Fair recommendation (7-8/14); 3) Weak recommendation (5-6/14); and 4) Expert opinion (2-4/14). Any single source suggestion was included as a comment. Highly scored recommendations included definition of urgent/emergent cases that required surgery; surgery for acute airway obstruction; prompt diagnosis of suspected cancer; and surgical intervention for sepsis following initial first-line medical management. Other well scored recommendations included senior faculty to perform the surgery; the use of open approaches rather than endoscopic ones; and avoidance of powered instruments that would aerosolize virus-loaded tissue. A tracheostomy should be performed on a case by case basis where key technical modifications become necessary. CONCLUSIONS: The COVID-19 pandemic will have a profound short and long-term impact on pediatric ENT practice. During this rapidly evolving climate, guidelines have been based on local practice and expert opinion. Until evidence-based practice in the COVID era is established, a comprehensive set of recommendations for pediatric ENT surgical practice based on a review of currently available literature and guidelines, is therefore, appropriate.

Postoperative Disposition Following Pediatric Sistrunk Procedures: A National Database Query.

OBJECTIVE/HYPOTHESIS: Variability exists in the postoperative disposition of children following Sistrunk procedures. Management options include discharge home versus overnight observation, with the latter allowing monitoring for immediate postoperative complications, presumably reducing the need for subsequent readmission. This study investigates the association between overnight observation and ambulatory management of children undergoing Sistrunk procedures and relevant postoperative complication and revisit rates to clarify best practice for these patients. METHODS: This was a retrospective database review using the Pediatric Health Information System database from 2007 to 2016. RESULTS: The cited dataset identified 6,434 qualifying patients, categorized into ambulatory versus overnight observation cohorts. The overall 30-day revisit rate was 4.9%; the revisit rate with overnight observation (6.1%) was higher than for ambulatory patients (3.8%, adjusted odds ratio (OR) 1.60; 95% confidence interval (CI): 1.21, 2.12). Revisit rates were significantly higher in patients 2 years of age or younger compared to older patients (6.7% vs. 4.3%). The rates of return to the operating room for the observation versus ambulatory groups were 1.8% and 0.5%, respectively. Cervical fluid collection and neck swelling were among the most common revisit indications in both groups, with a mean time to presentation of 9 days. CONCLUSIONS: This study demonstrates that ambulatory management following a Sistrunk procedure is not associated with increased rates of common postoperative complications, readmission, or need for secondary surgical intervention. A Sistrunk procedure may be safely performed on an ambulatory basis in select cases. LEVEL OF EVIDENCE: IV Laryngoscope, 131:E2352-E2355, 2021.
