Functional Endoscopic Sinus Surgery (FESS)

The use of endoscopes for endonasal interventions in the paranasal sinuses are essential tools which allow functional use in anatomical structures related to nasal mucus membranes.

Functional Endoscopic Sinus Surgery (FESS) involves opening and clearing of the paranasal sinus system. Contrary to earlier operating methods, which were frequently carried out using open interventions, endoscopic methods preserve anatomical landmarks. Radical clearances of the nasal and paranasal mucosa are avoided using the endoscopic technique.

Indications for Functional Endoscopic Sinus Surgery (FESS) are as follows:

  • Complete prevention of nasal breathing as a result of advanced nasal polyps, or in cystic fibrosis or by medialization of the lateral nasal wall
  • Orbital complication
  • Intracranial complication
  • Antrochoanal polyp
  • Mucocele or mucopyocele
  • Rhinosinusitis caused by fungal allergy
