Functional Endoscopic Sinus Surgery (FESS)

What Is Functional Endoscopic Sinus Surgery? 

Medical treatment is administered for chronic sinusitis in which sinusitis continue for at least 3 months. However, in the cases which do not respond to the medical treatment, surgical treatment is administered. 

One of the surgical intervention methods is Functional Endoscopic Sinus Surgery (FESS). Functional Endoscopic Sinus Surgery (FESS) is a minimally invasive surgical treatment which is administered by opening or expanding the flow paths between nasal cavity and sinuses near the nasal cavity by using nasal endoscopes in order to regulate the impaired ventilation of sinuses. Since it aims to normalize the functions of sinuses, it is called as “functional”.

Since endoscopes are practical and small enough to pass through the nasal cavity, a surgical intervention can be performed without the need for incisions in the outer area of face. Although intervention is mostly performed under general anesthesia, local or sedation anesthesia is also possible.

At the end of the operation, tampon, silicon splits with air holes enabling patients to breathe, or any liquid-absorbent materials can be placed inside nose; however, there are also cases where nothing is placed inside nose. Furthermore, together with sinusitis surgery, if necessary, concha resection/reduction, nasal cartilage/bone deviation surgeries can be performed, as well.  

Under Which Conditions is Functional Endoscopic Sinus Surgery Performed? 

Functional Endoscopic Sinus Surgery is performed in chronic sinusitis cases where sinusitis continue for at least 3 months, and in situations where no recovery is achieved or complaints repeat upon a short-term recovery after the medical treatments administered with antibiotics, antihistamines, decongestants, painkillers, and nasal sprays.

Since many factors cause sinusitis symptoms, a surgical intervention should be decided after confirming diagnosis of chronic sinusitis by means of endoscopic imaging and computed tomography.

Are There Any Complications of Functional Endoscopic Sinus Surgery?

Generally, patients can back to their normal daily lives generally within 1-2 weeks after being discharged on the operation day or the following day. Bloody discharge may occur during this period, but nose is not washed out; mostly nasal sprays, antibiotics, or painkillers are used. Under the doctor's supervision, any scar or sclerosis occurring in the inner part of the nose can be cleaned. In each period of the recovery process, face area should be protected from impacts and occurrence of trauma should be prevented.

How Long Does Functional Endoscopic Sinus Surgery Take?

Functional Endoscopic Sinus Surgery usually takes 2 to 4 hours depending on the condition of each patient and problem. 

What Are Risks of Functional Endoscopic Sinus Surgery?

     As with other surgeries, Functional Endoscopic Sinus Surgery has some risks. 

The risk of infection that may be encountered in all surgical interventions also applies to the functional endoscopic sinus surgery. The same is also valid for risk of anesthesia.

           During or after the operation, severe bleeding can occur due to the high sensitivity of the intranasal and sinus areas. Hospitalization or transfusion because of excessive blood loss is rarely seen. 

           In the case of damaging the cerebral cortex during the intervention, there is a risk of penetrating cerebral spinal fluid (CSF) into the nasal cavity. In such case, infection from the nose and sinuses to the brain can be seen. 

           There may be decrease in sense of smell after sinus and nose surgeries.

           Short- or long-term temporary visual impairment and double vision cases can arise after the operation. Rarely unilateral visual loss can occur. 

           Temporary numbness on the areas of lip and teeth; and swelling or bruising on the area of eye and mouth can happen. 

How Much Does Functional Endoscopic Sinus Surgery Cost?

Since each case and condition requires a separate diagnosis and treatment, it is not possible to give general information about Functional Endoscopic Sinus Surgery. The cost varies depending on the level of sinus problem, and whether there is a need for an intervention for intranasal bone and cartilage structure.
