Background Data And Objective:
Surgery for recurrent sinusitis with diffuse polyposis is challenging since tortuous sinus anatomy and bleeding tendency can make revision surgery particularly difficult. We report the efficacy in using KTP laser under the assistance of endoscope to perform sinus clear-out procedure for patients with recurrent ethmoid polyposis.
Materials And Methods:
Thirteen patients with recurrent ethmoid polyposis underwent this procedure between November 1996 and July 2000. All were available for follow-up. Patients all had a KTP sinus clear-out procedure (15-20 W continuous mode, spot size 0.4-0.8 mm, contact or near-contact approaches) assisted by endoscope. Sinus endoscopic findings, CAT scan data, operation records and perioperative courses were retrospectively reviewed. The mean follow-up period was 24.7 +/- 11 months.
Results:
Surgeries all went smoothly with minimal bleeding incurred. All patients demonstrated significant improvement in their sinonasal symptoms. Two cases (15.4%) had localized recurrent polyps.
Conclusion:
With its excellent capabilities in hemostasis, great intra-nasal maneuverability, and flexible operation modes, KTP laser is an ideal alternative to manage recurrent ethmoid polyposis for selected cases.
