[New method and instrument for maxillary surgery as an alternative to Caldwell-Luc operation]

A trocar of a novel design for maxillary surgery reduces to minimum operative injury of the cheek soft tissue and bone wall of the sinus providing an effective approach to sinus lesions. It enables widening of the sinus anastomosis by means of the diamond drill and forceps under microscope and endoscope control. The design of the instrument allows the surgeon to operate without the assistant's help. The duration of the operation is reduced, postoperative period runs uneventfully, with minimal negative responses of the cheek soft tissue and sublabial wound. Postoperative complications (subcutaneous emphysema and blood accumulation in the sinus) are corrected by irrigation or disappear spontaneously. The experience gained in operations on 180 patients and 248 sinuses provided the efficacy of the trocar in the removal of the polyps, foreign bodies, fungal masses and cysts both in children and adults.
