Otologic complications following the use of a high-speed air-turbine handpiece

The use of high-speed instruments may result in subcutaneous air in the face and neck. Hearing loss and otalgia have been added to the previously reported sequelae. Careful use of air-driven high-speed handpieces around areas of weakened and disrupted oral tissues may help avoid subcutaneous emphysema. Awareness of this entity plays a significant role in appropriate diagnosis and treatment.
