Initial clinical experience with balloon dilation in revision frontal sinus surgery.
OBJECTIVE
The purpose of this study was to determine whether balloon dilation is effective in revision frontal sinus surgery.


METHODS
We retrospectively reviewed all patients who had previously undergone endoscopic frontal sinus surgery and had persistent sinusitis. All patients then underwent balloon dilation of the frontal ostium. Outcome measurements included endoscopic patency of the frontal ostium, Lund-Mackay scores, culture-positive postoperative infections, and subjective persistence of symptoms.


RESULTS
Twenty-four frontal ostia and recesses were dilated in 13 patients. The mean follow-up was 13 months (range, 7 to 19 months). During follow-up, 21 of 24 ostia (86%) remained patent and 3 required additional procedures. Postoperative computed tomography scans were performed an average of 12 months after dilation (range, 6 to 18 months) in 9 patients (17 sinuses). The average Lund-Mackay score was 1.35 before dilation and 0.87 at follow-up (p = 0.0076), with 41% of sinuses (7 of 17) displaying radiographic improvement. The average number of postoperative infections was 2.07 (range, 0 to 7). Frontal headaches persisted in 38% of patients (5 of 13) at follow-up.


CONCLUSIONS
Balloon dilation of the frontal ostia has a posttreatment patency rate comparable to those of other endoscopic revision techniques. Although it may not fully address the frontal sinus disease of all patients, it is a less invasive technique that may be helpful for some patients.
