Bioabsorbable steroid-releasing sinus implants in the frontal and maxillary sinuses: 2-year follow-up.

BACKGROUND

Mometasone furoate-releasing implants have been approved for use in the ethmoid sinuses following endoscopic sinus surgery (ESS) to reduce the need for medical and surgical intervention postoperatively. Outcomes have not yet been studied when these implants are utilized in other paranasal sinuses after ESS.

OBJECTIVE

To present a case in which bioabsorbable steroid-eluting implants were used to maintain patency and to decrease inflammation in the frontal and maxillary sinuses after revision ESS.

METHODS

52-year-old male with lifelong allergic rhinitis, chronic allergic fungal rhinosinusitis, and inflammatory bowel disease had previously undergone four endoscopic sinus surgeries, subcutaneous injection immunotherapy, and topical therapy with budesonide and amphotericin sinus irrigations. In July, 2012, during revision left frontal sinusotomy and right maxillary antrostomy (the fifth ESS), two bioabsorbable steroid-releasing implants were placed in the left frontal recess and the right maxillary sinus respectively and followed clinically, endoscopically, and radiographically for two years.

RESULTS

Two year followup demonstrated near complete clinical, endoscopic, and radiographic resolution of the patient's signs and symptoms of chronic rhinosinusitis.

CONCLUSIONS

The steroid-releasing implants during the critical phase of wound-healing appear to have allowed the patient, now over two years postoperatively, to achieve a healthier state and to allow more successful management than the preceding 15-20 years.
