Abstract:
Type III frontal sinusotomy: surgical technique, indications, outcomes, a multi-university retrospective study of 120 cases. Draf type III is one of the advanced endonasal endoscopic surgeries for the frontal sinus. It was popularised by W. Draf in 1991. The procedure – which is also known as the modified endoscopic Lothrop procedure – aims to create the largest possible anteroposterior and lateral to lateral opening between both frontal sinuses and the nasal cavities. This requires the resection of the medial floor of both frontal sinuses, the intersinus septum and the superior nasal septum. The authors present a retrospective study including a cohort of 120 patients who underwent surgery in six Belgian university ENT departments. Mean follow-up was 24.6 months (range: 5-36 months). This paper describes the surgical procedure and reviews the indications, comorbidities, outcomes and complications of the type III frontal sinusotomy. Some correlations are also established with the data published in the worldwide literature. The authors conclude that the Draf III is a demanding procedure requiring considerable expertise in endoscopic sinus surgery. The procedure is effective with a success rate of 87.5%. Indeed, 12.5% of patients only experienced closure of the neoostium while 20% of all the patients had unchanged or worse symptomatology. The percentage of post-operative complications is 7.5%. All complications were managed successfully.
