Nasal endoscopy

Nasal Endoscopy

 Nasal endoscopy allows the examination of the nasal cavity in a way that was not possible just a few years ago. The diagnostic procedure is also known by the name of DNE or diagnostic nasal endoscopy, which differentiates it from the surgical, therapeutic use of the very same instrument. The device used for this procedure is a miniature telescope with a flexible body attached to a screen that receives real time images from inside of the nose.

Nasal endoscopy is used to diagnose and in some cases treat a long list of nasal conditions, which procedures are commonly conducted in the otolaryngologist’s office. Nasal endoscopy cost ranges from $250 to $400, but this standard price does not include medical consultation and result interpretation.

Diagnostic nasal endoscopy:


  • Evaluates non-responsiveness to medication
  • Determines if surgical procedure is necessary
  • Examines the results of sinus surgery
  • Determines the effects of severe allergies, immune deficiencies and disorders affecting mucons membranes and cilia (mucociliary disorders)
  • Determines nasal obstructions in the nasal cavity such as polyps and tumors
  • Determines foreign bodies lodged in the nasal cavity
  • Removes nasal obstructions
  • Determines if infections have moved beyond sinuses
  • Diagnoses chronic sinusitis in asthmatic children
  • Diagnoses loss of smell (anosmia)
  • Evaluates discharges from nasal cavities
  • Diagnoses facial pain and headaches

Nasal Endoscopy Procedure

Mainly used for observing nasal mucosa, sinonasal anatomy and nasal pathology, DNE also involves the evaluation of the sinus and nasal passage with direct vision.

Before the nasal endoscopy is performed, topical anesthetic (4% xylocaine) is used to pack the nasal cavity, in the inferior, middle and superior meatus, and left in place for 5 minutes.

Depending on the patient, different types of nasal endoscopy may be used. Various angulations (0 degrees, 30 degrees, 45 degrees and 70 degrees), and different sizes (2.7 mm and 4 mm) are available for the convenience of adults and children alike.

The examination consists of three phases:

  1. The nasal endoscope is introduced along the floor of the nasal cavity, from the middle turbinate (both superior and inferior surfaces) to both eustachean tubes.
  2. The nasal septum and the sphenoid ostium are studied.
  3. The crucial middle turbinate is evaluated by its shape and size in relation with the nasal wall and the septum.

Nasal Endoscopy Surgery

Nasal endoscopy surgery, also known as sinus surgery, is an outpatient procedure performed under general anesthesia. The same scope used during the diagnostic endoscopy, is now used in the surgery, but its camera is complemented with special surgical instruments.

Nasal endoscopy surgery is most commonly conducted to remove sinus obstructions, cure sinusitis and nasal polyps.  As for complications, besides slight tissue damage and minimal pain afterwards, it is considered a very safe procedure.
