[Conservative surgical treatment for large maxillary cysts. Some comments on technique (author's transl)]

Conservative surgical treatment for large maxillary cysts consists of releasing the cystic wall of the bony cavity without destroying the pulp of the teeth which have apices close to the operated cavity (unless the tooth is already dead). The vestibular approach is through one or two orifices and is as small in size as possible. This technique generally allows conservation of the vitality of the largest number of teeth and avoids postoperative collapse.
