ESS had similar degrees of improvement in SNOT-22 score.
TABLE XII-14 Evidence for ostium size in sinus surgery Study Year LOE Study Design Study Groups Clinical Endpoint Conclusions Hathorn 1990 2015 2 RCT Patients with CRS and frontal sinus disease who were randomized to receive balloon dilation on 1 side vs Draf 2a frontal sinusotomy on the contralateral side Frontal sinus ostial patency Mean blood loss Balloon dilation was associated with similar ostial patency rate as Draf2a but with lower mean blood loss (58 mL vs 91mL). SNOT-22 score at 3 months

No statistically significant difference in outcomes between the 2 groups.

At 1 year after the intervention:
ostium patency by CTscan 3. RS episode frequency
4. Change in Work Productivity and
Activity Impairment survey scores
1. Change in SNOT-20 2. Maxillary sinus
Bizaki 1980 2014 2 RCT Patients with chronic or recurrent RS without severe findings on sinus CT were randomized to receive ESS or balloon sinus dilation.
Bikhazi 1800 2014 2 RCT Patients with chronic maxillary sinusitis (with or without chronic anterior ethmoid
sinusitis) that failed medical therapy received:
1. In-office maxillary sinus balloon dilation 2. Maxillary antrostomy with or
without anterior ethmoidectomy
