FESS Treatment in Miyapur, Mathrusreenagar

What is FESS?

Functional endoscopic sinus surgery is the modern approach to surgery on the sinuses. In the past operations were designed to maximize drainage by gravity. As such large holes were fashioned into the sinuses and most of the lining tissue was removed. It is now known that this lining tissue plays a critical role in keeping sinuses healthy. As such the old-style surgery not infrequently worsened the problem.

Functional endoscopic sinus surgery places an emphasis on function. Given that we now know how important the normal anatomy and lining of the sinuses are to sinus health, the surgery is all about establishing ventilation and drainage along the normal pathways with maximum preservation of normal structures and in particular the sinus linings. The surgery is now a minimal rather than an extensive destructive procedure.

The availability of high definition cameras and very fine endoscopes allows for much greater control during the surgery and hence significantly better results.

Indications for FESS

Functional endoscopic sinus surgery may be indicated in the following common conditions;

  • Recurrent acute sinusitis
  • Chronic sinusitis
  • Nasal polyps
  • Allergic rhinosinusitis

The operation

Functional endoscopic sinus surgery is performed in hospital, usually under a general anaesthetic but can be performed with local anaesthesia and intravenous sedation.

Using fine endoscopes and high-definition cameras it is possible to obtain an excellent view. The area that most frequently needs to be dealt with is called the ostiomeatal unit.

It is an area on the sidewall of the nose where many of the sinuses drain. By removing a small amount of bone in this area improved ventilation and drainage can usually be achieved. Not infrequently there are anatomical variations in this area that make people prone to sinus disease. These can be readily corrected at the surgery. In more extensive sinus disease there may be a need to operate on other sinuses such as the sphenoid and frontal sinuses.
