Choanal Polyp Originating From Uncinate Process of Nasal Cavity

Area of Science:

• Otolaryngology
• Rhinology
• Pathology

Background:

• Choanal polyps are benign, solitary soft tissue lesions originating from nasal or paranasal sinus mucosa.
• They typically progress through sinus ostia into the nasopharynx, with antrochoanal polyps being the most common type.
• Ectopic origins include the nasal septum, sphenoid sinus, ethmoid sinus, turbinates, and meatus.

Purpose of the Study:

• To report a rare case of choanal polyps originating from the uncinate process of the nasal cavity.
• To review the existing literature on ectopic origins of choanal polyps.

Main Methods:

• Case presentation of a 52-year-old woman with choanal polyps.
• Literature review of reported ectopic origins of choanal polyps.

Main Results:

• A rare case of choanal polyps originating from the uncinate process was identified.
• The uncinate process has not been previously reported as an ectopic origin for choanal polyps.

Conclusions:

• The uncinate process represents a novel ectopic origin for choanal polyps.
• This case expands the understanding of the anatomical origins of choanal polyps.
