Endoscopic transnasal surgery in antrochoanal polyp

Area of Science:

• Otolaryngology
• Surgical Innovation
• Nasal Endoscopy

Background:

• Antrochoanal polyps often require surgical removal of both nasal and antral components.
• Current methods for antral part removal include Caldwell-Luc or various meatal antrostomies.
• Endoscopic techniques offer potential for less invasive antral polyp management.

Purpose of the Study:

• To evaluate the efficacy and safety of endoscopic surgery for antrochoanal polyps.
• To assess the removal of the antral polyp component through the middle meatus.
• To introduce and evaluate novel endoscopic instruments for polyp removal.

Main Methods:

• Endoscopic surgery was performed on 22 patients with antrochoanal polyps.
• The antral component was accessed and removed via the middle meatus.
• Two new instruments were designed to facilitate complete antral part removal through the maxillary ostium.
• Diagnostic and therapeutic endoscopic findings were used to discuss controversial aspects of antrochoanal polyps.

Main Results:

• Complete endoscopic removal of the antral part of the polyp was achieved in all cases.
• Endoscopic follow-up ranging from 6 to 30 months (average 20 months) showed no recurrence.
• The procedure was successfully performed as an outpatient treatment.

Conclusions:

• Endoscopic surgery through the middle meatus is a safe and reliable treatment for antrochoanal polyps.
• This minimally invasive approach can be conducted effectively as an outpatient procedure.
• Novel instruments may enhance the completeness of antral polyp removal via endoscopic means.
