[Cystostomia. Preliminary surgery for a voluminous cyst].

The Authors present a case of voluminous dentigerous mandible cysts, treated by cystostomy as described by Partsch and resected after eighteen months, when the radiographical tests showed a remarkable reduction of its dimension. The Authors, even if they prefer the radical technique of operation as their choice in the treatment of the cystic forming of the jaw, underline the importance of an accurate clinical and X-ray valuation in the choice of the surgical protocol to follow in the treatment of the cysts of great dimension.
