Paranasal sinuses

The use of endoscopes means that endonasal interventions in the paranasal sinuses are today a surgical method which allows functional and anatomical structures related to the mucus membrane to be taken into account.

Functional Endoscopic Sinus Surgery (FESS) involves openings and clearances 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
