What Patients Need to Know Before an Ear, Nose, and Throat Endoscopy

1. Nasal and Sinus Endoscopy

Step 1: Five minutes before the endoscopy, the nurse places two cotton swabs soaked with a topical vasoconstrictor and local anesthetic into the patient’s nasal cavities.

Step 2: The patient lies on their back on the examination bed with both arms resting alongside the body and breathes through the mouth.

Step 3: The physician removes the two cotton swabs and sequentially inserts the endoscope into each nostril to examine and assess pathological findings.

2. Ear Endoscopy

Step 1: The patient lies on their back on the examination bed with both arms resting alongside the body.

Step 2: The physician sequentially inserts the endoscope into each ear to examine and assess pathological findings.

3. Pharyngeal and Laryngeal Endoscopy

Step 1: Five minutes before the endoscopy, the nurse sprays a local anesthetic into the patient’s throat.

Step 2: The patient sits with both hands resting on the thighs, leans forward, opens their mouth, and sticks out their tongue while the physician inserts the endoscope into the throat to examine and assess pathological findings.

Step 3: The patient continuously says “ee...ee...ee...” until instructed by the physician to stop and breathes through the nose.

4. Endoscopy Procedure

4.1. Receive the Endoscopy Order

After examination, the physician may order nasal and sinus, ear, or pharyngeal and laryngeal endoscopy.

4.2. Wait for Your Number to Be Called

Take a queue number at the patient reception counter.

Wait for your number to be called before entering the Endoscopy Room.

4.3. At the Endoscopy Room

Patients should inform the physician of any history of diabetes, hypertension, or medication allergies.

Patients enter the endoscopy room when their number is called.

Patients undergoing throat endoscopy will receive a local anesthetic spray in the throat.

Patients undergoing nasal endoscopy will have anesthetic-soaked cotton swabs placed in the nose.

Patients should maintain the position instructed by the physician during the procedure.

Ear, nose, and throat endoscopy is an essential method that supports accurate diagnosis of ear, nose, and throat conditions.

Patients do not need to fast before the endoscopy.

Results are provided immediately in the Endoscopy Room.

When necessary, the physician will provide consultation and, with the patient’s consent, perform a biopsy to obtain a sample of suspicious tissue for pathological examination.

After the biopsy, the patient will receive treatment to control bleeding at the biopsy site and will be scheduled for a follow-up appointment to receive the pathology results.
