Multiple bioabsorbable corticosteroid-eluting stent placement with associated skull base injury.

Bioabsorbable corticosteroid-eluting sinus stents (BCES) are used to optimize healing after sinus surgery. We report a patient with BCES placed through a dural defect. A 70 year old underwent sinus surgery. Postoperatively, the patient developed mental status changes. The patient was taken to the operating room and eight BCES were identified, with one extending through the skull base. The stents were extracted and the defect was repaired. The patient recovered well. This is the first significant complication associated with BCES. Thorough review of preoperative imaging, understanding of skull base anatomy, and careful use of BCES are critical for safety. LEVEL OF EVIDENCE: NA Laryngoscope, 129:1494-1496, 2019.
