Utilization of sinus stents as a novel approach for benign cystic lesions of the sella

Steroid-releasing sinus stents have emerged as a safe and effective tool in endoscopic sinus surgery. In this case report, we present two patients with recurrent cystic sellar masses. Transsphenoidal approach was used to access the sella. Following resection and drainage of the cystic pathology, a Propel (Menlo Park, CA) stent was placed through the corridor of the resection site to stent the cavity open. This is the first report where a steroid-releasing sinus stent was used in the treatment of a sellar lesion. It supports that this technology is safe and effective for use in skull base surgery.
