The antrochoanal polyp is a particular pathology of nasal fossae and sinuses. Since the first description made by Killian, several pathogenic mechanisms and surgical techniques have been reported. The polyp exeresis is classically made using the Caldwell-Luc approach The antrochoanal polyp is a rare, benign, nasal polyp found primarily in children. The risk factors leading to its etiology are unclear. Comprising nasal mucosa, it originates in the maxillary sinus and can cause symptoms of nasal obstruction. The polyp can be definitively diagnosed on CT Antrochoanal polyp is a benign polypoid lesion orginating from the maxillary sinus antrum and extending to the choana. Our aim was to assess the clinical presentation and associated rhinological findings of antrochoanal polyp patients and to evaluate results of 2 surgical treatments termed endoscopic sinus surgery (ESS) and ESS plus mini. The antrochoanal polyp, a benign solitary polypoid lesion, usually arises in a maxillary sinus, opacifying and enlarging the sinus cavity without bone destruction. It passes through the ostium of the sinus into the choana, and from there into the posterior nasopharynx. The soft tissue mass does not erode or destroy contiguous soft tissue or.

Ethmoidal polyps arise from the ethmoid sinuses and extend through the middle meatus into the nasal cavity. Antrochoanal polyps usually arise in the maxillary sinus and extend into the nasopharynx and represent only 4-6% of all nasal polyps Antrochoanal polyp, which is also known as Killian's polyp is a benign solitary lesion with a mucin density. It arises from the antrum of the maxillary sinus and passes through the sinus ostium into the nasal cavity, choana and goes downwards into the nasopharynx.

Our aim was to investigate the light microscopic and ultrastructural features of ACP and to compare these with nasal polyps originating from the middle meatus (MMP). Seven ACP and seven MMP specimens were evaluated by transmission.
  2. Antrochoanal polyps are the most common type of choanal polyp.
