The sinuses are cavities lined with mucus and occupied by air. They communicate to the nose through small holes. As long as they are working properly, we do not notice them, but when they are frequently involved in infectious or inflammatory processes, they produce symptoms. When this happens, we speak of sinusitis. Sinusitis is caused by a blocked, inflamed, or infected sinus.

What is endoscopic sinus surgery?

It is the name given to the surgery that helps us treat acute recurrent sinusitis, chronic sinusitis refractory to medical treatment, nasal polyposis, the refection of some tumors and the repair of neurological and orbital defects, among others. It is usually done through the nose and does not need incisions in the skin or mouth.

How is the surgery performed?

It is performed under general anesthesia and using the transnasal route using rigid endoscopes, a television camera, and projection on a television screen. This is the safest and least invasive method for the treatment of maxilloethmoid and frontal sinusitis.

What happens after surgery?

After surgery, your nose may feel a little blocked by a nasal packing. Nasal obstruction can last for several days even after the plugs are removed. The nose should not be blown for a while and it is preferable to apply drops of saline solution to allow the secretions that are produced to be cleaned.

When can you return to work?

It is usually performed on an outpatient basis, although the patient must rest at home for the first few days.

What are the possible complications?

  • Bleeding : it is a risk in the operation.
  • Eye problems : The sinuses are very close to the orbit, so sometimes there may be bruises on the eyelids.
  • Cerebrospinal fluid fistula : The sinuses for nasals are located very close to the base of the skull.

How often do complications occur? In general, major complications are very rare. Minor complications such as nosebleeds are more frequent.
