The true choanal polyp-a case report

Area of Science:

• Otolaryngology
• Rhinology
• Pathology

Background:

• Large polyps in the nasal pharynx can originate from various sinonasal sites, including the maxillary antrum, ethmoids, or choanae.
• The precise origin of these polyps is often unclear, and existing literature provides limited definitive guidance.
• Choanal polyps are histologically similar to common nasal mucous polyps, despite their distinct location.

Observation:

• A 65-year-old male presented with a long-standing sensation of nasal fullness.
• Clinical examination revealed a polypoid mass protruding below the soft palate into the nasopharynx.
• Radiographic imaging (roentgenograms) did not provide contributory diagnostic information.

Findings:

• A rare choanal polyp was successfully removed using a minimally invasive technique involving a nasal snare and a soft wire.
• The polyp was threaded into a wire loop passed through the anterior nares into the pharynx.
• Complete polyp removal was achieved without any intraoperative bleeding.

Implications:

• This case highlights a practical and effective method for the endoscopic removal of choanal polyps.
• The described technique offers a bloodless and efficient approach for managing such rare sinonasal masses.
• Accurate preoperative differentiation of polyp origin may remain difficult, emphasizing the importance of surgical expertise and technique.
