Draf III is an effective salvage procedure for recalcitrant chronic frontal sinusitis.

Ethmoidectomy without frontal sinusotomy may achieve

similar QoL improvement for

those with less severe sinusitis.

TABLE XII-17 Evidence for extent of frontal sinus surgery Study Year LOE Study Design Study Groups Clinical Endpoint Conclusions Zhang 2020 2020 2 Randomized trial Patients with CRSwNP requiring revision surgery randomized into 3 groups: ESS, “Radical ESS (RadESS)” and RadESS with DrafIII. Follow-up for minimum 5 years, assessing polyp recurrence, symptom scores, endoscopic scores, revision surgery rates, and clinical control of asthma. Radical ESS (surgery addressing all sinuses, and performing partial middle turbinate resection), and RadESS with Draf III yielded similar

outcomes, both superior than ESS (addressing all sinuses

including frontal sinusotomy).

Comparable long term outcome between the 2 groups, but with patients achieving this sooner in the Draf IIb group.
