Frequency of recurrence of nasal polyposis post endoscopic polypectomy.

      Аннотация: Endoscopic sinus surgery (ESS) is a minimally invasive technique that uses an endoscope to improve ventilation and drainage in addition to polyp removal, The extent of surgery varies according to the extent of disease and surgeon's individual practice. Nasal polyps are round, soft, semi-translucent, pale or yellow glistening structures that originate from any part of the nasal mucosa or Paranasal sinuses (although most commonly from the ethmoid or middle meatus regions, may be growing in many large cases so that it fills most of the nasal cavity. microscopic examination shows that nasal polyps contain large amounts of fibrous connective tissue and inflammatory cells in addition to the presence of large numbers of capillaries and covered with thin layer of squamouscells applied. The objective of this study is to discover the frequency of recurrence of nasal polyposis after endoscopic sinus surgery (ESS) and associated factors that may predispose to recurrence.
