What is an choanal polyp?

Choanal polyps are defined as solitary soft tissue lesions mostly originating from sinuses and extending toward the choana by passing through the sinus ostia. Although chronic rhinosinusitis (CRS) and allergy have been implicated, the exact cause of CPs is not known.

Where does antrochoanal polyp arise from?

Antrochoanal polyps (ACP) are benign lesions that arise from the mucosa of the maxillary sinus, grow into the maxillary sinus and reach the choana, and nasal obstruction being their main symptom.

Why is it called antrochoanal polyp?

Discussion. 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.

How is antrochoanal polyp treated?

Surgery is the usual treatment for antrochoanal polyps. The primary aim of treatment for antrochoanal polyp is complete removal with total clearance of the maxillary sinus. Herein, we present 36 cases of children with antrochoanal polyps (ACPs). All patients underwent preoperative radiological assessment by CT scan.

Can nasal polyps be cancerous?

Nasal polyps are abnormal growths inside the nasal cavity or paranasal sinuses. Most nasal polyps are benign (not cancer) and are caused by some type of chronic (long-lasting) inflammation in the nose. Using exams and tests, doctors can often tell benign polyps from cancer.

How are antrochoanal polyps diagnosed?

The gold standard for diagnosing an antrochoanal polyp is a CT scan showing a hypodense mass arising from an enlarged, opacified maxillary sinus. The polyps do not cause bony destruction. However, when large, they can expand and enlarge the ostium.

How do you diagnose an antrochoanal polyp?

Does antrochoanal polyps bleed?

Introduction. The presence of a bleeding nasal mass is consistent with various malignant and benign lesions. Among the benign lesions are angiomatous antrochoanal polyps (AAP), juvenile nasopharyngeal angiofibroma (JNA) and nasal septal hemangioma or “bleeding polyps which was first reported by Ash and Old in 1950.

Is antrochoanal polyp common?

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.

What does antrochoanal mean?

(an″trō-kō′ă-năl) [ antro- + choanal] Pert. to both the maxillary antrum and the cavity that connects the nasopharynx and nasal cavity.

Symptoms: Symptoms are similar to findings of sinus disease: pain, pressure, drainage, headache, breathing disturbances.

Does antrochoanal polyp bleed on touch?

Clinical photography of sinonasal angiomatous polyp. Notes: Sinuscopy revealed a huge antrochoanal polyp which bled easily when touched (A) with some reddish, bluish, necrotic gray area (B).

Do antrochoanal polyps bleed?

Do nasal polyps need to be biopsied?

In general, no special preparation is necessary when the polyp is located in the nose or another open, easily accessible area of the body. However, you’ll need to prepare for a biopsy if the polyp is located in an organ inside your body, such as the colon or uterus.

Can a surgeon tell if a polyp is cancerous?

Most polyps are benign (not cancerous). Your doctor can tell if a colon polyp is cancerous during a colonoscopy by collecting tissue to biopsy. The results of the biopsy are typically sent to your doctor within a week. Only 5% to 10% of all polyps become cancerous.

Can nasal polyps cause blocked ears?

Sometimes overgrowth of tissues in the back of the nose (such as nasal polyps or the adenoids) can cause ear blockage by obstructing the eustachian tube opening.
