Surgical Treatment of the Oroantral Fistula in a Patient with Myasthenia Gravis: Clinical Considerations and Anesthetical Management

Myasthenia gravis (MG) is an autoimmune neuromuscular disease characterized by muscle weakness and fatigue. MG affects neuromuscular junctions and is characterized by the development of antibodies immunoglobulin G against postsynaptic acetylcholine receptors cause disease. Definitive diagnosis is made by electromyogram. Women are more affected than men. Fluctuating weakness and easy fatigability of skeletal muscles are observed when the limbs are involved. The weakness may involve a single muscle group or may be generalized. The muscle group is the ocular muscles and often causes diplopia and ptosis. On this rare occasion, careful perioperative anesthetic management is required to avoid lifethreatening complications in both intraoperative and postoperative periods. In this case report, a 47 -year -old female patient with MG requiring oroantral fistula treatment is described. Anesthetic management was performed under local anesthesia using appropriate doses, and the postoperative patient follow-up was uneventful.
