ABSTRACT

OBJECTIVE: To analyze patients' return to normal activity, pain scores, narcotic use, and adverse events after undergoing tonsillectomy or adenotonsillectomy with monopolar electrocautery or radiofrequency ablation. STUDY DESIGN: Randomized double-blinded clinical trial based on prospective parallel design. SETTING: Academic medical center and tertiary children's hospital between March 2018 and July 2019. METHODS: Inclusion criteria included patients aged ≥3 years with surgical indication of recurrent tonsillitis or airway obstruction/sleep-disordered breathing. Patients were randomly assigned to monopolar electrocautery or radiofrequency ablation. Patients were blinded to treatment assignment. Survey questions answered via text or email were collected daily until postoperative day 15. The primary outcome was the patient's return to normal activity. Secondary outcomes included daily pain score, total amount of postoperative narcotic use, and adverse events. RESULTS: Of the 236 patients who met inclusion criteria and were randomly assigned to radiofrequency ablation or monopolar electrocautery, 230 completed the study (radiofrequency ablation, n = 112; monopolar electrocautery, n = 118). There was no statistically significant difference between the groups in the number of days for return to normal activity (P = .89), daily pain scores over 15 postoperative days (P = .46), postoperative narcotic use (P = .61), or return to hospital for any reason (P = .60), including bleeding as an adverse event (P = .13). CONCLUSIONS: As one of the largest randomized controlled trials examining instrumentation in tonsillectomy, our data do not show a difference between monopolar electrocautery and radiofrequency ablation with regard to return to normal activity, daily pain scores, total postoperative narcotic use, or adverse events.

ABSTRACT

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has highlighted safety concerns surrounding possible aerosol-generating procedures, but comparative data on the smallest particles capable of transmitting this virus remain limited. We evaluated the effect of nasal endoscopy on aerosol concentration and the role of a high-efficiency particulate air (HEPA) filter in reducing aerosol concentration. METHODS: Otolaryngology patients were prospectively enrolled in an outpatient, cross-sectional study. Demographic information and clinic room characteristics were recorded. A scanning mobility particle sizer and GRIMM aerosol monitor measured aerosols 14.3 nm to 34 µm in diameter (i.e., particles smaller than those currently examined in the literature) during (1) nasal endoscopy (± debridement) and (2) no nasal endoscopy encounters. One-way analysis of variance (ANOVA) and Student's t test were performed to compare aerosol concentrations and impact of HEPA filtration. RESULTS: Sixty-two patients met inclusion criteria (25 nasal endoscopy without debridement; 18 nasal endoscopy with debridement; 19 no nasal endoscopy). There was no significant difference in age or gender across cohorts. Aerosol concentration in the nasal endoscopy cohort (± debridement) was not greater than the no nasal endoscopy cohort (p = 0.36; confidence interval [95% CI], -1.76 to 0.17 µg/m3 ; and p = 0.12; 95% CI, -0.11 to 2.14 µg/m3 , respectively). Aerosol concentrations returned to baseline after 8.76 min without a HEPA filter versus 4.75 min with a HEPA filter (p = 0.001; 95% CI, 1.73-6.3 min). CONCLUSION: Using advanced instrumentation and a comparative study design, aerosol concentration was shown to be no greater during nasal endoscopy versus no endoscopy encounters. HEPA filter utilization reduced aerosol concentrations significantly faster than no HEPA filter.
