What is Endoscopic Sinus Surgery?

14:35 - 9 April , 2021

Medical procedure



It is a minimally invasive surgical procedure whose objective is to open the drainage holes of the sinuses to sanitize them if there are recurrent infections or inflammatory processes such as sinusitis. It is also used for the extraction of tumors or malformations in said area. 

It is also frequently used to treat ophthalmic conditions and chronic nosebleeds. 


General anesthesia is given to you and the doctor inserts an optical fiber through your nose that will allow it to obtain a detailed view of the sinuses and using endoscopic surgery instruments, unblocks the obstructed orifices, removing the damaged or inflamed tissue. 

Depending on how complicated and lengthy the procedure was, you may go home that day or have to stay in the hospital for up to three days.

Potential complications:

The sinus cavities are located in an area where there are different nearby structures, both vascular and the eye socket, the skull cavity, and the tear duct, among others, so it is possible that some of them may suffer some damage during the process. 

Minor complications include:

  • Slight bleeding.
  • Temporary loss of smell.
  • Headache, facial, or tooth pain.
  • Bruises.

More serious complications can also occur, but are rare:

  • Profuse bleeding.
  • Permanent loss of smell.
  • Severe damage to the tear duct.
  • Injury to the carotid artery.
  • Double vision and visual loss.
  • Cerebrospinal fluid leakage.
  • Meningitis.
  • Accumulation of air in the cranial cavity.
