Prevention of antrochoanal polyp
recurrence was enabled by endoscopy of the nose and maxillary sinus.
Haziness of sinuses was found in 19 cases of antrochoanal polyp
and 16 cases of ethmoidal polyp.
1998) (16) and Bachert and Van Cawenberger (17) (1977) described that IL-5 has a chemotactic effect for eosinophils, and its synthesis is increased in nasal polyposis when compared to healthy mucosa or antrochoanal polyp
On left side, normal findings were observed in 49%, Antrochoanal polyp
was observed in 3(3%) and AC polyp with DNS in 1(1%), Adenoid in 1(1%), DNS again was the most common single pathology (16%), ethmoidal polyps in 3(3%), maxillary sinusitis in 9%, mass in nasal cavity in 1%, nasal polyposis in 1%, pan-sinusitis in 2%, polypoidal mass with DNS in 1%, Frontal sinusitis in 2% and sinusitis with DNS in 1%.
Case report of a mass that mimicked an antrochoanal polyp
Pre operative biopsy was not done since the clinical, endoscopic and radiological evaluation revealed features consistent with antrochoanal polyp
8,12) CT of the paranasal sinuses is necessary to identify the characteristic features of a sphenochoanal polyp so that it can be differentiated from an antrochoanal polyp
and to determine the anatomic landmarks for endoscopic sinus surgery.
However, combined approaches should be performed to avoid recurrences, unless removal of antral part of the antrochoanal polyp
completely by endoscopic resection is possible.
Patients with an antrochoanal polyp
often present with unilateral nasal obstruction, but if the polyp extends into the nasopharynx, bilateral obstruction may occur.
Surgical, radiologic, and histologic findings of the antrochoanal polyp
In some cases, a polyp may extend posteriorly into the choana or the nasopharynx and present as an antrochoanal polyp
The stalk of the antrochoanal polyp
was found to be protruding from the natural ostium of the left maxillary sinus.
