Abstract

Background: We conducted a pilot study comparing estimated blood loss (EBL) using coblation-assisted endoscopic sinus surgery (CAESS) where coblation is used to debulk nasal polyps before microdebridement with a traditional microdebrider technique in chronic rhinosinusitis (CRS) patients with sinonasal polyps undergoing endoscopic sinus surgery (ESS). Methods: A retrospective analysis was performed at a tertiary care center on patients with nasal polyposis undergoing ESS between January 2008 and July 2008. The University of Miami CT staging system was used preoperatively to evaluate the extent of sinonasal disease. The duration of surgery, blood loss per minute, total EBL, and demographic data were collected. Results: Twenty-one patients underwent nasal polypectomy/ESS using CAESS and 16 patients underwent nasal polypectomy/ESS using microdebridement. The two groups had comparable University of Miami CT staging scores (p > 0.05). The average EBL was 307.1 ± 169.8 mL using coblation compared with 627.8 ± 424.2 mL using microdebridement (p < 0.05). The average duration of surgery using coblation was 116.2 ± 41.7 minutes, compared with 125.3 ± 48.4 minutes using microdebridement (p > 0.05). The average blood loss per minute was 2.8 ± 1.7 mL in the coblation group compared with 4.8 ± 2.1 mL in the microdebridement group (p < 0.05). Subgroup analyses showed a significant decrease in average EBL and EBL/minute to be only significant for revision cases (p < 0.05) and not for primary cases (p > 0.05). Conclusion: Coblation-assisted nasal polypectomy/ESS is associated with a statistically significant lower EBL and blood loss per minute when compared with traditional microdebridement technique. Coblation represents a new device that can reduce blood loss in patients with nasal polyposis undergoing traditional revision ESS. Further prospective randomized trials are needed to validate these findings.
