Changing trends in otorhinolaryngological diseases at a non-government clinic in Jaipur

Abstract

Background

Otorhinolaryngological (ENT) diseases are major health problem in India but the trends in occurrence of various disorders in clinical practice have not been well studied. To assess the types of such diseases and to determine changing trends in their incidence we performed this study.

Methods

The study was done at a non-government ENT center at Jaipur. From 1975 to 2005, >125000 patients of different diseases were evaluated here. The study includes randomly selected patients (n = 11454) from years 1980 to 2000 at an interval of 5 years to evaluate disease trends. Significance of trends was evaluated using least squares regression.

Results

In the years 1980, 1985, 1990, 1995 and 2000 mean age of patients was 26.60 ± 17.81 (range 0.16 to 85), 27.07 ± 16.91 (0.08 to 90), 28.30 ± 17.73 (0.25 to 90), 28.79 ± 17.8 (0.25 to 90) and 28.74 ± 17.81 (0.25 to 85) years respectively. 51 types of ENT diseases were observed of which 19 contributed to 76.8% (8807) patients and analysis was restricted to them. Chronic suppurative otitis media (2203, 19.2%), otitis externa (859, 7.5%), deviated nasal septum with nasal obstruction (717, 6.3%) and chronic tonsillitis (695, 6.1%) were the most common, followed by ear wax (569, 4.9%), sensorineural hearing loss (545, 4.7%), chronic rhinosinusitis (428, 3.7%) and epistaxis (320, 2.8%). There was increasing trend for stomatitis (b = 0.0014), deviated nasal septum (b = 0.0290), allergic rhinitis (b = 0.0023), epistaxis (b = 0.0002), acute tonsillitis (b = 0.0003), hoarseness (b = 0.0017), deaf mutism (b = 0.0005), sensorineural hearing loss (b = 0.0038), tinnitus (b = 0.0006) and ear wax (b = 0.0050). Declining trend was observed for chronic rhinosinusitis (b = −0.0155), otitis externa (b = −0.0063), chronic suppurative otitis media (b = −0.0001), acute otitis media ( = −0.0007), secretory otitis media (b = −0.0013), otosclerosis (b = −0.0007), vertigo (b = −0.0007), neck swelling (b = −0.0005) and chronic tonsillitis (b = −0.0194).

Conclusion

This study from an Indian urban ENT center shows a significantly increasing trend in chronic and degenerative ear diseases and decline in infection related diseases.
