Nasal And Laryngeal Endoscopy
A nasal and laryngeal endoscopy is a diagnostic procedure that allows for quick evaluation of the nasal passages and the larynx in a safe, minimally invasive manner. An endoscopy is a medical procedure that inserts an instrument called an endoscope, a thin, flexible tube, into the body to provide a detailed view and images that may be projected onto a computer screen.
Often referred to as a laryngoscopy, the procedure involves the use of an endoscope called a laryngoscope. The laryngoscope, which usually has tiny a light or video camera attached, is passed through each nostril, providing a detailed view of the larynx and nasal cavity.
REASONS FOR A NASAL AND LARYNGEAL ENDOSCOPY
A laryngoscopy may be performed by a doctor to find out the causes of various nose and throat problems that may include:
- Difficulty swallowing
- Voice problems
- Ear or throat pain
- A lump or mass in the throat
THE LARYNGOSCOPY PROCEDURE
Patients are commonly sedated with general anesthesia. Additional medication and an anesthetic may be applied to the nose and throat to open the nasal and throat passages and keep the areas numb. The doctor inserts the laryngoscope into the nose and gently guides it down the throat. The doctor can view the nasal passages, larynx and vocal cords. In some cases, a biopsy may be performed to collect a tissue sample. The examination takes about 20 to 30 minutes. After the procedure, the patient’s throat may be sore and they may not be able to eat anything for several hours.
RISKS OF NASAL AND LARYNGEAL ENDOSCOPY
Although it is considered a routine and safe procedure, there are risks associated with a laryngoscopy that may include:
- Blocking of the airways
- Bleeding if a biopsy was performed
After the laryngoscopy, the doctor will discuss the results with the patient and develop a customized treatment plan based on the patient’s individual condition.
