title: Antrochoanal polyp - Validating its origin and management by endonasal endoscopic sinus surgery (eess).
abstract: OBJECTIVE
  20 fresh cases of Antrochoanal Polyps were subjected to EESS for studying the site of origin and to validate its efficacy.
  
  
  METHODS
  This was a prospective study in which the cases were subjected to surgery and were followed; up for evaluation of results.
  
  
  METHODS
  The surgery performed was an endoscopic endonasal sinus surgery preceded and followed by transcanne sinuscopy. Results/Findigs: The age at the time of presentation ranged from 7-35 years. Male to female ratio was 1:1:5. Occurrence Antrochoanal Polyp was 1.5 times more common on the left side. The mean duration of symptoms was 3 years. The main presenting symptom was unilateral nasal obstruction in 100% of cases. Allergic symtomps.were noticed in 10%. Vasmotor symptom were present in 15% of the patients. Antroscopy revealed the antral part.to be cytic in 100% of the cases. The site of origin of the polyp could be ascertained in only 12 out of 20 cases; in 7 of them it acrose from the infrolateral wall of maxillary sinus, in 2 from the infromedial wall und in 2 it appeared to arise from the supromedial wall while in 1 from margin of the ostium. Post-surgery intra-natral remnants were found in 3 out of 20 cases i.e. in 15% of them. In two cases it was removed through maxillary ostia but in one case removed through transcanine route.
  
  
  CONCLUSIONS
  Endoscopic Sinus Surgery is the best modality of treating Antrochoanal Polyps. We report a success rate of 95% in our series.
