Endoscopic sinus surgery procedure using CO2 laser and/or microresector for paediatric and adult chronic sinusitis with antrochoanal polyp (ACP), with long-term follow-up, was examined. Twelve children and 13 adults underwent the surgical procedure.
The following two techniques were used to remove the antral portion of an ACP with a 70°endoscope:
(1) CO2 laser – The base of the ACP was vaporized and removed via an enlarged natural ostium with a pipe-guide handpiece with a deflective tip.
(2) Microresector – The ACP was resected via
an enlarged natural ostium and/or nasoantral window opened under the inferior turbinate with the curved and straight blade of a microresector.
In the endoscopic follow up for 10 to 57 months, no patient who underwent the primary surgery required reoperation for ACP recurrence. One out of
the seven patients who underwent secondary surgery required a revised operation with microresector and CO2 laser.
