Antrochoanal Polyp Management
I need to clarify that antrochoanal polyps (ACPs) are benign sinonasal lesions arising from the maxillary sinus that extend into the nasal choana—these are NOT colonic polyps 1. The term "coloanal" appears to be a misspelling or confusion with either "antrochoanal" (sinus polyps) or "colonic/colorectal" polyps.
If This is an Antrochoanal (Sinus) Polyp:
Surgical removal via functional endoscopic sinus surgery (FESS) is the definitive treatment for antrochoanal polyps 1.
Clinical Presentation
- ACPs occur predominantly in children and young adults and are almost always unilateral 1
- The most common presenting symptoms are nasal obstruction and nasal drainage 1
Diagnostic Evaluation
- Nasal endoscopy is the primary diagnostic technique for visualizing the polyp 1
- Computed tomography (CT) scan is essential to determine the exact origin and full extent of the polyp 1
- The differential diagnosis must include all causes of unilateral nasal obstruction 1
Treatment Approach
- FESS with powered instrumentation for complete polyp removal is the standard of care and is extremely safe and effective 1
- Complete removal of the polyp including its origin point in the maxillary antrum is critical to prevent recurrence 1
- The etiopathogenesis remains unclear, but these are benign lesions with no malignant potential 1
Key Clinical Pitfall
- Failure to identify and remove the exact origin of the polyp in the maxillary sinus is the primary cause of recurrence 1
If This is a Colonic/Colorectal Polyp:
Please refer to the detailed colorectal polyp management guidelines, which involve colonoscopic evaluation, size-based resection strategies, and histologic assessment for malignancy risk 2, 3, 4.
