Diagnosis And Treatment of Antro Choanal Polyp
Antrochoanal polyp is a benign solitary polypoidal lesion arising from the maxillary sinus antrum causing opacification and enlargement of antrum radiologically without any evidence of bone destruction. It exits the antrum through the accessory ostium reaches the nasal cavity, expands posteriorly to exit through the choana into the post nasal space.
It commonly affects children and young adults. The antrochoanal polyp is dumb bell shaped with three components i.e. antral, nasal and nasopharyngeal.
Its etiology is still unknown.
How to Make Diagnosis?
Nasal Endoscopy, CT /MRI Scan are the main diagnostic techniques.
How it is treated?
Surgery is the indicated treatment for ACP, with endoscopic resection the most recommended. Simple avulsion of the polyp has a high rate of recurrence, whereas the Caldwell-Luc procedure combined with FESS gives better result.
