Although most patients with frontal rhinosinusitis improve with medical therapy, those with persistent symptoms resulting from anatomic obstruction of the frontal sinus drainage pathways may be candidates for surgery. Over the past decade, traditional external approaches to the frontal sinus have been largely replaced by endoscopic procedures.1 These are performed with a small-diameter rigid endoscope that is passed through the nostril, avoiding the need for facial incisions. Instruments passed alongside the endoscope are used to remove obstructing tissue and drain the infected sinus.
