Navigation Assisted Frontal Sinus Osteoplastic Flap Surgeries - A Case Series.

Osteoplastic flap surgery of the frontal sinus is still a relevant surgical technique for frontal sinus pathologies despite advancements in endoscopic techniques due to the complex anatomy of frontal sinus and limitations of endoscopic techniques for certain pathologies. The most crucial step in this surgery is accurate delineation of the frontal sinus pneumatisation which guides the osteotomies and this is conventionally done with radiographs which is not without errors. Here we present three cases where we have utilized image guidance technology for osteoplastic flap surgery of the frontal sinus with superior results.
