Role of Thermography in the Diagnosis of Chronic Sinusitis

Sumario: | Introduction Thermography is a form of radiography that images the skin surface temperature. Thermograms are pictorial representations of thermal maps of the entire body’s outer surface. Thermography was applied as an attempt to evaluate its usefulness in the diagnosis of chronic sinusitis (CS). Hence, this study was done to determine the diagnostic value of thermography for patients suffering from CS. Methodology Patients attending the Department of Otorhinolaryngology and Head and Neck Surgery over a two years' duration with symptoms suggestive of CS were included in this diagnostic evaluation study. X-ray paranasal sinuses (PNS) and nose, thermography of head and neck, and computed tomography (CT) of PNS and nose (axial and coronal sections) were performed on them. The thermograms and X-ray sinuses obtained were compared with the computed tomography of PNS findings. Results The study population consisted of 167 patients (75 males and 92 females) and the mean age of the study population was 38.6 years. The sensitivity and specificity of thermography of the head and neck in diagnosing frontal, ethmoidal, maxillary, and sphenoidal sinusitis were 92.59% and 68.58%, 100% and 66.32%, 70.06% and 85.88%, 99.18% and 0%, respectively. Whereas the sensitivity and specificity of the X-ray PNS and nose in diagnosing frontal, ethmoidal, maxillary, and sphenoidal sinusitis were 92.59% and 77.88%, 73.61% and 81.05%, 89.19% and 98.92%, 74.44% and 99.18%, respectively. Conclusion Thermography is better than X-rays in diagnosing frontal and ethmoidal sinusitis and as good as X-ray PNS and nose in diagnosing maxillary sinusitis. Thermography failed to pick up sphenoidal sinusitis. The advantages of thermography are that it is a radiation-free, non-invasive, and cost-effective method for diagnosing CS. |
