2. © EDP Srl, 2004 http://www.edpsrl.com Ear, Nose and Throat Diseases In ENT diseases infrared thermography may be applied for: - primary diagnostics of acute inflammation processes in the nose and nasal sinuses, throat, larynx; - dynamic thermographic examinations during the treatment to control the effectiveness of the performing therapy. Infrared thermography is a very suitable method, because it’s fast, reliable, non-contact and absolutely safe for patient and doctor. Infrared thermography has no limitations and it can be successfully applied in babies, children and pregnant women.

Forehead has a symmetrical thermal image. Front neck area has a symmetrical thermal image, too. In some cases little warm lines along the carotid vessels may be found. Usually in men with a big laryngeal prominence, this part of the neck appears as a cold area. Normal thermogram

4. In the case of rhinitis the nose appears warm. The temperature gradient between the affected area and sides of the nose can be from 0,8-1,2°C (allergic rhinitis) up to 2,5°C (diphtheritic rhinitis). © EDP Srl, 2004 http://www.edpsrl.com Rhinitis Allergic rhinitis. Nose temperature is equal to forehead temperature. Acute both sides rhinitis.Chronic rhinitis, acute condition in the right side.

5. © EDP Srl, 2004 http://www.edpsrl.com Nasal septum deviation Nasal septum deviation to the right side. Often chronic inflammation process into the nose is kept by the deviation of the nasal septum. In these cases in thermograms the nose is non- symmetric with a clear deviation.

The temperature gradient depends on the individual specificity of the patient and stage of inflammation, so it’s possible to perform an objective control during the treatment. Acute frontitis. Acute right side sinusitis. Acute right side sinusitis, associated with frontitis.

Pharyngitis has a similar thermographic picture, but the hyperthermic area is located a bit further down, and a severe reaction of the local lymphatic nodes takes place. Acute laryngitis. Acute pharyngitis. Severe inflammatory reaction of the sub- mandibular lymphatic nodes.

The possibility of infrared thermography to diagnose acute otitis is especially actual in babies. Left side acute otitis.Right side acute otitis.Left side acute otitis.
