Balloon Sinuplasty and Stenting in the Management of Complex Frontal Sinus Outflow Tract Fractures.

Objective: Classical management of complex fractures involving the frontal sinus outflow tract (FSOT) favors obliteration or cranialization to avoid delayed complications. We aim to exhibit success with a novel application of balloon sinuplasty and frontal stenting in the management of complex injuries disrupting the FSOT, which might have otherwise required more invasive interventions.

Study Design: Retrospective review.

Setting: Single institution, level 1 trauma center.

Methods: Retrospective review of patients presenting to a level 1 trauma center with fractures involving the FSOT. Outcomes include patency of the FSOT on imaging and endoscopy, rate of complications, degree of residual tabular displacement, and need for revision surgery.

Results: Twenty-five patients met inclusion criteria, with complete FSOT obstruction seen in all cases on computed tomography. All patients underwent balloon sinuplasty with frontal sinus stenting; 48% underwent concurrent anterior table repair, and 36% open repair of nasoorbitoethmoid complex fractures. The mean follow-up length was 13.9 months, at which time 91.3% of patients demonstrated radiographic and endoscopic FSOT patency. No residual sinus opacification or pneumocephalus was observed.

Conclusion: Balloon sinuplasty with frontal sinus stenting is a straightforward and minimally invasive technique that can create a safe sinus in complex fractures disrupting the FSOT while avoiding the need for more invasive procedures.
