To assess the applicability of the piezoelectric device in translabyrinthine-approach exposure of the internal auditory canal. In three cases with vestibular schwannoma, the bone around the internal auditory canal was completely removed by means of piezosurgery. Evaluation was performed by an experienced surgeon, and a second relatively inexperienced surgeon. Irrespective of surgical experience, piezosurgery proved to be a safe method for exposure of the internal auditory canal. Compared with the conventional procedure it provides an improved surgical view and more precise bone removal in a narrow operating field. This novel technique has the characteristics to reduce the corresponding risk of accidental slipping with consequent thermal and mechanical injury to the dura and neurovascular structures. The major disadvantage of piezosurgery is the longer time required for bone removal. The micro-oscillating piezoelectric device is a useful adjunct to the rotating burr during removal of the bone around the internal auditory canal in translabyrinthine approach. It could reduce the risk of injury to neurovascular structures at the bone-to-soft tissue interface.

D007758	Ear, Inner	The essential part of the hearing organ consists of two labyrinthine compartments: the bony labyrinthine and the membranous labyrinth. The bony labyrinth is a complex of three interconnecting cavities or spaces (COCHLEA; VESTIBULAR LABYRINTH; and SEMICIRCULAR CANALS) in the TEMPORAL BONE. Within the bony labyrinth lies the membranous labyrinth which is a complex of sacs and tubules (COCHLEAR DUCT; SACCULE AND UTRICLE; and SEMICIRCULAR DUCTS) forming a continuous space enclosed by EPITHELIUM and connective tissue. These spaces are filled with LABYRINTHINE FLUIDS of various compositions.

D009464	Neuroma, Acoustic	A benign SCHWANNOMA of the eighth cranial nerve (VESTIBULOCOCHLEAR NERVE), mostly arising from the vestibular branch (VESTIBULAR NERVE) during the fifth or sixth decade of life. Clinical manifestations include HEARING LOSS; HEADACHE; VERTIGO; TINNITUS; and FACIAL PAIN. Bilateral acoustic neuromas are associated with NEUROFIBROMATOSIS 2.
