Microscopy means carrying out a detailed examination of the external canal and ear drum using an operating microscope for magnification. The normal eardrum is only about 1 cm in diameter, so enlarging this by x4 or higher results in more accurate diagnostic information.
Typically the examination chair is reclined so that the patient’s head can be stablised on the headrest to prevent even minor movements, which could cause discomfort. A single-use sterile plastic speculum is introduced into the earhole and the overhead microscope swung into position. It is a painless short procedure.
