Implication of American Society of Anesthesiologists Physical Status (ASA-PS) on tonsillectomy with or without adenoidectomy outcomes.

BACKGROUND: The American Society of Anesthesiologists Physical status classification (ASA-PS) is a simple categorization of a patient's physiological status during the perioperative period. The role of ASA-PS in predicting operative risk and complications following tonsillectomy with or without adenoidectomy (T ± A) has not been studied. The objective of the study was to identify the association of the pre-operative ASA-PS with 30-day complication rates and adverse events following T ± A. STUDY DESIGN: A retrospective analysis was performed using data from the American College of Surgeons' National Surgical Quality Improvement Program database (ACS NSQIP) of patients aged 16 years or older who underwent T ± A between 2005 and 2016. Patients were stratified into ASA-PS Classes I/II and III/IV. Patient demographics, preoperative comorbidities, pre-operative laboratory values, operation-specific variables, and postoperative outcomes in the 30-day period following surgery were compared between the two subsets of ASA-PS groups. RESULTS: On multivariate analysis, patients with ASA class III and IV were more likely to experience an unplanned readmission (OR 1.39, 95 % CI 1.09-1.76; p = 0.007), overall complications (OR 1.49, 95 % CI 1.28-1.72; p < 0.001), major complications (OR 1.52, 95 % CI 1.31-1.77, p ≤ 0.001), reoperation (OR 1.33, 95 % CI 1.04-1.69; p = 0.022), and extended length of stay >1 day (OR 1.78, 95 % CI 1.41-2.25; p < 0.001) following a T ± A. CONCLUSION: Higher ASA-PS classification is an independent predictor of complications following T ± A. Surgeons should aim to optimize the systemic medical conditions of ASA-PS classes III and IV patients prior to T ± A and implement post-operative management protocols specific to these patients to decrease morbidity, complications, and overall health care cost.

Utility of telemedicine in tracheostomy-dependent children.

Objectives: Telemedicine can improve access to pediatric otolaryngology care by decreasing travel time and cost, and lowering the risk of viral transmission during the SARS-CoV-2 (COVID-19) pandemic. This study aims to identify the clinical role and outcomes of telemedicine for tracheostomy-dependent children before and during the COVID-19 pandemic. Methods: Retrospective chart review of 42 tracheostomy-dependent pediatric patients who utilized telemedicine between October 2013 and April 2020 (pre-COVID-19), and 111 patients who utilized telemedicine between May 2020 and July 2021 (during COVID-19) at a tertiary free-standing children's hospital outpatient clinic. Results: The majority of pre-COVID-19 telecommunication solely addressed tracheostomy stomal concerns as compared with during COVID-19 (99% vs. 3%, p < .001), while telecommunication during COVID-19 was mainly used for routine follow-up as compared with pre-COVID-19 (99% vs. 0%, p < .001). Telemedicine visits during COVID-19 were significantly less likely to result in the need for in-person office visits as compared with those pre-COVID-19 (4% vs. 22%; p < .001). There was no significant difference in urgent emergency department (ED) evaluation following telemedicine pre- and during COVID-19 (16% vs. 11%). The most common reasons for ED presentation both pre- and during COVID-19 following telemedicine visit included respiratory distress, dislodged tracheostomy tube, and tracheostomy bleeding. Conclusion: The clinical role of telemedicine has evolved from problem-based evaluation to routine follow-up during the COVID-19 pandemic. Although telemedicine can decrease the need for in-person office evaluation of routine tracheostomy concerns, respiratory complications and tracheostomy bleeding still require urgent in-person ED evaluation. Level of evidence: Level 4.

Ultrasound-guided ethanol sclerotherapy for multifocal unilateral Warthin's tumor after partial parotidectomy.

Introduction: Warthin's tumor, also known as papillary cystadenoma lymphomatosum, is one of the most common benign salivary gland neoplasms. The current first-line treatment for Warthin's tumor is parotidectomy. However, surgical resection has the risk of complications including facial nerve weakness and Frey's syndrome. Recently, ultrasound-guided ethanol sclerotherapy (UGES) has been found to be efficacious in the treatment of a variety of head and neck lesions. Case report: We present a patient with multifocal Warthin's tumor who was managed with partial parotidectomy and two cycles of ultrasound-guided ethanol sclerotherapy. Discussion: Ethanol sclerotherapy has been used as a minimally invasive alternative to surgical excision or observation alone for a variety of head and neck masses. To our knowledge, this is the first case presented in the literature where sclerotherapy was used in conjunction with a partial parotidectomy. Minimizing the extent of surgical resection can reduce the risk of facial nerve weakness and Frey's syndrome and negate the need for fat grafting for defect reconstruction. Conclusion: UGES may serve as a safe and reliable procedure that can be performed in conjunction with partial parotidectomy for patients who wish to achieve definitive diagnosis while also minimizing the risk of complications associated with extensive parotidectomy.

Efficacy of ethanol ablation as a treatment of benign head and neck cystic lesions.

OBJECTIVE: To evaluate the efficacy and safety of ethanol ablation in the treatment of benign head and neck cystic lesions. METHODS: A total of 25 patients who received ethanol ablation (EA) of head and neck cystic lesions by an otolaryngologist at a single institution between October 2017 and October 2020 were identified. Patient demographics, clinical characteristics, treatment details, and treatment outcomes at follow up visits were obtained by retrospective review of electronic medical records. RESULTS: 25 patients who underwent ethanol ablation of head and neck cystic lesions were included, with a mean age of 49.1 years old (Interquartile range (IQR),32.5-65.5 years) and 12 males (47.0%). The most common cysts treated with EA were thyroglossal duct cysts (n = 8, 32.0%) and lymphoepithelial parotid cysts (n = 7, 28.0%). The mean volume prior to treatment was 10.57 mL (IQR, 1.58-8.81 mL). Mean volume following EA was 1.30 mL (range, 0.10-0.97 mL) with 74.40% cyst reduction by volume (IQR, 48.56-96.29%) (p = 0.002). The mean time to the last follow-up was 5 months (range, 3-6 months). One patient received surgery despite treatment success to obtain a definitive diagnosis of the mass. No other patients received further surgical management. The treatment success of EA, as defined by >70% volume reduction or the resolution of symptoms, was 92.0%. All patients were satisfied with the outcome and had no reported complications. CONCLUSION: EA is an effective and safe alternative to surgery for the treatment of head and neck cystic lesions that can be performed in an outpatient setting by an otolaryngologist.

Optimization of COVID-19 testing accuracy with nasal anatomy education.

IMPORTANCE: Adequate sampling of the nasopharynx is crucial to performing accurate SARS-CoV-2 (COVID) testing. Formalized education of nasal anatomy may improve provider testing technique and reduce false-negative test results. OBJECTIVE: To assess the effect of nasal anatomy education on medical providers' comfort level and knowledge base in performing accurate SARS-CoV-2 (COVID) testing. STUDY DESIGN: Pre-post survey. SETTINGS: Tertiary care academic hospital. PARTICIPANTS: 17 nurses performing COVID testing were enrolled. INTERVENTION: An educational session on COVID nasopharyngeal testing technique and nasal anatomy was presented by an otolaryngologist. MAIN OUTCOMES AND MEASURES: A pre-session survey assessed providers' prior nasal testing training and COVID testing challenges. Provider comfort level with COVID testing was surveyed pre-and post-session. A 6-question nasal anatomy test was administered pre- and post-session. RESULTS: 16 out of 17 nurses performed fewer than 10 COVID tests prior to the educational session (94%). Reported challenges with COVID testing included patient discomfort (79.6%), inability to pass the test swab (23.5%) and nasal bleeding (11.8%). The number of providers comfortable with independently performing COVID testing increased from pre- to post-session (5 and 14, p = 0.013). The average number of correct responses to the 6-question nasal anatomy test increased following the session (3.2 ± 1.2 to 5.1 ± 1.1, p = 0.003). Specifically, the number of providers able to localize the nasopharynx increased from 8 providers pre-session to 14 providers post-session (p = 0.04). CONCLUSION: Early implementation of nasal anatomy and nasopharyngeal swab technique education can help improve provider comfort and knowledge in performing accurate COVID testing.

Impact of Diabetes Mellitus Following Tonsillectomy in Adults: A National Surgical Quality Improvement Program Analysis.

OBJECTIVES: To identify 30-day complication rates specific to patients with diabetes mellitus following tonsillectomy. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was used to identify patients undergoing tonsillectomy between 2005 and 2018. Patients were stratified into 3 cohorts: insulin-dependent diabetes mellitus (IDDM), non-insulin-dependent diabetes mellitus (NIDDM), and non-diabetes mellitus (NODM). Coarsened-exact-matching was utilized to account for baseline differences between cohorts. Outcomes studied included post-operate complications, prolonged hospitalization, and unplanned readmissions. RESULTS: A total of 986 DM and 26 774 NODM patients were included, and the mean age of patients undergoing tonsillectomy was 29.5 ± 11.6 and 28.7 ± 11.0 years, respectively. The majority of patients were female (70.5% for both DM and NODM cohorts) and White/Caucasian (89.2% vs 89.3%). Among patients undergoing tonsillectomy, a greater proportion of DM patients experienced an operative time greater than or equal to the 75th percentile (35 minutes; 25.9% vs 22.8%, P = .024), overall morbidity (12.6% vs 5.4%, P < .001), pneumonia (0.6% vs 0.2%, P = .036), and reoperation (10.2% vs 3.5% P < .001) in comparison to NODM patients. In an analysis between IDDM (n = 379) and NIDDM (n = 211) patients, IDDM patients were at an increased risk for prolonged hospitalization (1.4% vs 0.0%, P = .045), pneumonia (5.2% vs 0.5%, P < .001), urinary tract infections (3.3% vs 0.3% P = .004), major complications (15.6% vs 7.7%, P = .002), minor complications (19.9% vs 8.2%, P < .001), and overall complications (10.0% vs 1.3%, P < .001). CONCLUSION: DM patients are at a heightened risk for complications following tonsillectomy. Standardized protocols, careful pre-operative planning, and stringent glycemic management may help optimize patient outcomes.

Decrease in Respiratory Related Hospitalizations in Tracheostomy-Dependent Children Who Tolerate Passy-Muir Valve Use.

OBJECTIVE: To assess the effect of Passy-Muir® Valve (PMV) tolerance on respiratory illness and respiratory related hospital admissions in tracheostomy-dependent children. METHODS: Retrospective cohort study of 262 patients who underwent tracheostomy placement between 2012 and 2018 at a tertiary free-standing children's hospital. Outcome measures studied were number of reported upper respiratory infections and respiratory related hospitalizations per year (RRH/year). RESULTS: About 135 (51.5%) tracheostomy-dependent children underwent PMV trials, and 106 (78.5%) of these children were able to tolerate PMV for at least 1 hour daily. When comparing children who tolerated PMV versus those who did not, the latter group had significantly higher rates of subglottic stenosis but no significant differences in RRH/year or average age. In those children who tolerated PMV and achieved routine use of PMV > 1 hour/day, an average of 1.14 RRH/year occurred prior to PMV tolerance, as compared with 0.57 RRH/year after PMV tolerance (P = .003). Multivariate analysis shows that in patients <2 years, there is a significant decrease in RRH/year after PMV tolerance is attained (1.53 vs 0.76, P = .001), independent of indication for tracheostomy. CONCLUSION: In tracheostomy-dependent children who tolerate PMV use routinely >1 hour/day there are decreased rates of respiratory related hospitalizations (RRH). Children <2 years of age have the most impact of RRH, with rates that are significantly lower with routine use of the PMV.

Ultrasound-guided ethanol sclerotherapy for non-surgical treatment of Warthin's tumor.

BACKGROUND: Currently, the first line treatment for Warthin's tumor (WT) is parotidectomy. There is a paucity of data evaluating the safety and efficacy of non-surgical treatments for patients not amenable to surgery. Ultrasound guided ethanol sclerotherapy (UGES) has been successfully used for the management of lymphangiomans of the head and neck, thyroid nodules, and thyroid cysts. This is the first study to implement and assess the success of UGES for management of WT. METHODS: We report two patients with WT, with a total of 3 masses, who underwent UGES. All procedures were performed in the clinic. The primary outcome measured was the tumor volume reduction rate (VRR), patient satisfaction, and complications observed at follow-up. RESULTS: Both patients experienced a significant reduction in tumor size upon follow up. VRR for the three treated tumors were 67.30%, 98.32%, and 55.73%. Patient were very satisfied with the results and noted significant cosmetic improvement. No complications were observed at follow-up. CONCLUSIONS: Ultrasound guided ethanol sclerotherapy may be a viable option for conservative treatment of Warthin's tumor in patients unsuitable or unwilling to undergo surgical resection.

An evaluation of arytenoid prolapse following laryngotracheal reconstruction.

OBJECTIVES/HYPOTHESIS: Laryngotracheal reconstruction (LTR) is a collection of procedures used to treat pediatric laryngotracheal stenosis. Arytenoid prolapse is a potential postoperative complication that may lead to upper airway obstruction. This study investigates the incidence, risk factors, and need for surgical intervention for post-LTR arytenoid prolapse. STUDY DESIGN: Retrospective chart review. METHODS: The charts of 107 patients who underwent a total of 119 LTR procedures between 2005 and 2018 at a tertiary free-standing children's hospital were reviewed. RESULTS: The incidence of post-LTR arytenoid prolapse was 7.6%. Age, glottic involvement, tracheostomy status, vocal cord paralysis, and balloon dilation had no effect on arytenoid prolapse development. Sixteen percent of procedures performed in children <8 kg resulted in arytenoid prolapse, versus 4.5% of procedures performed in children >8 kg (P = .036). One hundred percent 100% of patients with post-LTR arytenoid prolapse had placement of a posterior graft. Multivariate analysis confirmed both weight <8 kg and posterior graft use to be significantly associated with arytenoid prolapse (P = .027 and .039, respectively). Three of the nine patients with arytenoid prolapse were symptomatic and weighed <8 kg at time of surgery. One required voice therapy; two required surgical intervention. CONCLUSIONS: The incidence of arytenoid prolapse is 7.6% following LTR. Patients undergoing posterior graft LTR or weigh <8 kg at time of surgery are more likely to develop arytenoid prolapse. Children <8 kg at time of surgery who develop arytenoid prolapse are more likely to be symptomatic and require further intervention. These findings are valuable for preoperative risk assessment of pediatric laryngotracheal stenosis management. LEVEL OF EVIDENCE: 4 Laryngoscope, 130:247-251, 2020.

Trigeminocardiac reflex in pediatric adenotonsillectomy: A report of two cases with literature review.

Trigeminocardiac reflex (TCR) is a physiological response that occurs due to stimulation of the trigeminal nerve, resulting in vagus nerve activation, parasympathetic dysrhythmia, and sympathetic hypotension. The pediatric population is vulnerable to TCR due to higher resting vagal tone, which can result in ischemia and death. This study reports two cases of TCR during adenotonsillectomy. Placement and rapid opening of a Crowe-Davis retractor led to immediate bradycardia and hypotension in two children undergoing adenotonsillectomy, which resolved upon release of the retractor. Early intraoperative recognition of TCR with removal of mechanical stimulation can resolve vital instability without need for chemical intervention. Laryngoscope, 130:803-805, 2020.

Sedation withdrawal following single stage laryngotracheal reconstruction: Does dexmedetomidine help?

OBJECTIVES: Single-stage laryngotracheal reconstruction (SS-LTR) requires a period of post-operative intubation, during which time adequate sedation is needed to ensure graft healing. Commonly used agents include benzodiazepines, opioids, and more recently, dexmedetomidine, a centrally-acting α2 adrenoreceptor. This study aims to compare withdrawal outcomes between various sedation regimens following SS-LTR. METHODS: Retrospective chart review of 56 patients who underwent SS-LTR between 2008 and 2018 at a tertiary free-standing children's hospital was performed. Of 47 patients with complete records, 18 patients received dexmedetomidine for >75% of their intubation period with midazolam (DexWM), 9 received dexmedetomidine for >75% without midazolam (DexWOM), and 20 received dexmedetomidine for <75% with midazolam (noDex). RESULTS: There was no significant difference in length of PICU or hospital stay between the groups. The noDex group trended toward a higher re-intubation rate of 25%, as compared with 11% of DexWOM and 5.6% of DexWM (p = 0.21). There was no significant difference in days of oral sedation taper required or Withdrawal Assessment Tool (WAT-1) score for post-extubation days 1 and 3. By post-extubation day 5, 100% of the DexWM group had WAT-1 scores <3 as compared with 71.4% of the noDex group (p = 0.037). Notably, lower average daily doses of dexmedetomidine and midazolam were used in the DexWM group, as compared with the DexWOM and noDex groups, respectively. CONCLUSION: Dexmedetomidine as a primary sedation agent with midazolam allows for adequate sedation following SS-LTR. The combination of the two drugs in the DexWM group not only reduced the dosage of each drug needed, but also significantly improved WAT-1 scores by post-extubation day 5, as compared with the alternative sedation regimens.

Quality of life outcomes following velopharyngeal insufficiency surgery.

OBJECTIVES: Velopharyngeal insufficiency (VPI) may be due to functional or anatomic causes, and can lead to speech deficits, communication difficulty, and emotional strain on patients and their caregivers. The VPI Effects on Life Outcomes (VELO) instrument quantifies quality of life outcomes in VPI patients both before and after VPI surgery. This study aims to identify pre-operative patient characteristics associated with better post-operative quality of life. METHODS: This study is a retrospective chart review of 51 patients who underwent VPI surgery between 2009 and 2018 at a tertiary free-standing children's hospital. A 26-item parent-proxy VELO questionnaire was administered by telephone to parents to assess their child's quality of life post-VPI surgery. RESULTS: Twenty-seven parents responded to the VELO questionnaire. Average post-operative VELO score was significantly higher in non-syndromic patients as compared with syndromic patients. Average post-operative VELO score was not significantly different between patients with and without submucous cleft (SMC) or those with mild to moderate versus severe pre-operative hypernasality. On multivariate analysis, absence of genetic syndrome, lack of submucous cleft, and presence of severe-pre-operative hypernasality were significantly and positively associated with increased post-operative VELO scores. CONCLUSION: Children who undergo VPI surgery are more likely to have better post-operative quality of life outcomes if their VPI was not associated with a genetic syndrome or submucous cleft. Non-syndromic and non-SMC patients with severe pre-operative hypernasality may benefit significantly from VPI surgery and have improved post-operative quality of life.

Safety and Perioperative Adverse Events in Pediatric Endoscopic Sinus Surgery: An ACS-NSQIP-P Analysis.

INTRODUCTION: This study describes safety outcomes of pediatric endoscopic sinus surgery (ESS) to identify risk factors for 30-day postoperative adverse events using the National Surgical Quality Improvement Program-Pediatric (NSQIP-P) database. METHODS: We performed a retrospective cohort study involving patients in the 2012-2015 NSQIP-P database who underwent ESS. Predictors included demographics, comorbidities and surgical acuity. Outcomes included 30-day complications, reoperations, and readmissions. RESULTS: Among 2,061 ESS cases identified, 1,829 (88.7%) were elective and 232 (11.3%) were urgent/emergent. There were 92 (4.5%) readmissions, 54 (2.6%) unplanned reoperations, and 61 (3.0%) complications. On multivariate analysis, readmission was associated with urgent/emergent procedures (OR 2.31, CI 1.36-3.93, p<0.01) and history of bleeding disorder (OR 2.24, CI 1.12-4.44, p = 0.02), reoperation was associated with urgent/emergent procedures (OR 5.78, CI 3.24-10.34, p<0.01), and complications were associated with urgent/emergent procedures (OR 3.81, CI 2.13-6.82, p<0.01) and history of bleeding disorder (OR 5.30, CI 2.74-10.20, p<0.01). Bleeding requiring transfusion was associated with urgent/emergent procedures (OR 9.61, CI 2.90-31.80, p<0.01), history of bleeding disorder (OR 14.16, CI 4.41-45.45, p<0.01), and age <3 years (OR 3.92, CI 0.99-15.61, p = 0.05). Black children were significantly more likely to undergo urgent/emergent surgery than white children (19.7% vs. 9.6%, p<0.01). CONCLUSIONS: This multi-institutional study confirms that while pediatric ESS is largely safe, urgent/emergent procedures carry the greatest risk of postoperative adverse events, and black children are significantly more likely to undergo higher acuity surgery than white children. Regardless of procedure acuity, young age and bleeding disorder are associated with higher risk of 30-day adverse events.

Advances in nano-based inner ear delivery systems for the treatment of sensorineural hearing loss.

Sensorineural hearing loss (SNHL) is one of the most common diseases, accounting for about 90% of all hearing loss. Leading causes of SNHL include advanced age, ototoxic medications, noise exposure, inherited and autoimmune disorders. Most of SNHL is irreversible and managed with hearing aids or cochlear implants. Although there is increased understanding of the molecular pathophysiology of SNHL, biologic treatment options are limited due to lack of noninvasive targeted delivery systems. Obstacles of targeted inner ear delivery include anatomic inaccessibility, biotherapeutic instability, and nonspecific delivery. Advances in nanotechnology may provide a solution to these barriers. Nanoparticles can stabilize and carry biomaterials across the round window membrane into the inner ear, and ligand bioconjugation onto nanoparticle surfaces allows for specific targeting. A newer technology, nanohydrogel, may offer noninvasive and sustained biotherapeutic delivery into specific inner ear cells. Nanohydrogel may be used for inner ear dialysis, a potential treatment for ototoxicity-induced SNHL.

IgG4-Related Disease of Bilateral Temporal Bones.

OBJECTIVE: IgG4-related disease (IgG4-RD) is an idiopathic inflammatory condition that causes pseudotumor formation in single or multiple organs, including those of the head and neck. Temporal bone involvement is rare, with only 3 cases of unilateral temporal bone IgG4-RD described in the literature. We report the first known case of IgG4-RD of bilateral temporal bones and describe its clinical presentation, diagnosis, and treatment. METHODS: The patient was a 52-year-old man with latent tuberculosis (TB) who presented with a 10-year history of bilateral profound hearing loss and vestibular dysfunction. Computed tomography and magnetic resonance imaging demonstrated bilateral labyrinthine destruction with invasion of the posterior fossa. RESULTS: Immunoglobulin level testing showed elevated total serum IgG levels with normal IgG4 levels. Bilateral mastoidectomies were performed, with biopsy samples demonstrating IgG4 staining with IgG4-positive plasma cells up to 40/HPF (high power field) on the right and 20/HPF on the left, consistent with bilateral IgG4-RD. CONCLUSION: IgG4-RD of bilateral temporal bones presents with chronic and progressive bilateral hearing loss and vestibular dysfunction. Clinical presentation and radiologic findings are nonspecific, and definitive diagnosis must be made with histopathology and immunostaining. Corticosteroids are therapeutic, but surgical resection may be necessary for temporal bone IgG4-RD to improve long-term remission.

Ankle-Brachial Index Testing at the Time of Stress Testing in Patients Without Known Atherosclerosis.

BACKGROUND: Individuals referred for stress testing to identify coronary artery disease may have nonobstructive atherosclerosis, which is not detected by stress tests. Identification of increased risk despite a negative stress test could inform prevention efforts. Abnormal ankle-brachial index (ABI) is associated with increased cardiovascular risk. HYPOTHESIS: Routine ABI testing in the stress laboratory will identify unrecognized peripheral arterial disease in some patients. METHODS: Participants referred for stress testing without known history of atherosclerotic disease underwent ABI testing (n = 451). Ankle-brachial index was assessed via simultaneous arm and leg pressure using standard measurement, automated blood-pressure cuffs at rest. Ankle-brachial index was measured after exercise in 296 patients and 30 healthy controls. Abnormal postexercise ABI was defined as a >20% drop in ABI or fall in ankle pressure by >30 mm Hg. RESULTS: Overall, 2.0% of participants had resting ABI ≤0.90, 3.1% had ABI ≥1.40, and 5.5% had borderline ABI. No patient with abnormal or borderline ABI had an abnormal stress test. Participants who met peripheral arterial disease screening criteria (age ≥65 or 50-64 with diabetes or smoking) tended toward greater frequency of low ABI (2.9% vs 1.0%; P = 0.06) and were more likely to have borderline ABI (0.91 to 0.99; 7.8% vs 2.9%; P = 0.006). Postexercise ABI was abnormal in 29.4% of patients and 30.0% of controls (P not significant). CONCLUSIONS: Ankle-brachial index screening at rest just before stress testing detected low ABI in 2.0% of participants, all of whom had negative stress tests.
