ABSTRACT
Background: Antrochoanal polyps (ACPs) are benign polypoidal mass originating from the maxillary sinus and they extend into the choana. The etiopathogenesis of ACP is not clear. These are found more commonly in children and young adults. ACP is almost always unilateral and common symptoms include nasal obstruction and nasal discharge. These lesions are extremely rare in the older adult age group. Materials and Methods: This is a retrospective study of 14 cases of ACPs managed between June 2017 and July 2022. Detailed clinical presentations, investigations, and treatment with surgical interventions for ACPs were studied. Results: Out of 14 cases of older adult patients with ACPs, there are 8 (57.14%) cases with a polyp on the left side and 6 (42.85%) cases on the right side of the nasal cavity. The most common symptom was constant and unilateral nasal obstruction in 12 (85.71%) patients, followed by purulent nasal discharge in 7 (50%) cases, clear rhinorrhea in 5 (35.71%) cases, facial pain in 4 (28.57%) cases, snoring in 3 (21.42%) cases, sneezing in 3 (21.42%) cases, and halitosis in 2 (14.28%) cases. Conclusion: ACPs are uncommon in the older adult age group. Diagnostic nasal endoscopy and computed tomography scans are important tools for the diagnosis of ACP. Functional endoscopic sinus surgery and power instrumentation are helpful for the complete removal of ACPs and are considered extremely safe procedures. Clinicians and otolaryngologists are often not aware of the prevalence of ACPs among the older adult age group.
