Facial paralysis following mastoid disease and operation.

An operation, performed by master facial surgeons Gillies and McIndoe, to correct a facial paralysis in a young man. The surgery is shown in detail and explained step by step through intertitles. Immediately after the operation, over-correction is noted in the patient. Later results show the patient's face with increased mobility and little scarring. A further patient, a young boy, with the same condition, is shown smiling and eating a biscuit.
