N2 - Acoustic otoscopy detects middle ear pathology by measuring the ability of the tympanic membrane to reflect sound. Fluid or thickening of the tympanic membrane increases sound reflection. We conducted a study to compare acoustic otoscopy with pneumatic otoscopy in identifying middle ear pathology in 80 children (160 ears) presenting to the emergency department with ear or upper respiratory complaints. We then evaluated the use of acoustic otoscopy in 34 adults (68 ears) with and without ear complaints. Using a reflectivity of 5 or more units to signify acute pathology in children, the sensitivity was 82%, and the specificity was 100%. Using a reflectivity of 6 or more units to indicate acute suppurative pathology in adults, the sensitivity was 83%, and the specificity was 95%. We found acoustic otoscopy to be objective, practical, and reproducible. We conclude that acoustic otoscopy is a valuable adjunct in the diagnosis of otitis media in children and adults.
