Myasthenia gravis
Myasthenia gravis (MG) is an autoimmune disorder of the neuromuscular junction causing fluctuating, fatigable muscle weakness (ocular, bulbar, limb, and sometimes respiratory muscles). Dental relevance: (1) risk of bulbar weakness affecting swallowing/airway during procedures, (2) myasthenic crisis risk (respiratory failure), (3) MULTIPLE antibiotics can worsen MG (fluoroquinolones, telithromycin, macrolides, aminoglycosides), (4) extreme sensitivity to sedatives/opioids due to limited respiratory reserve, and (5) stress/infection can precipitate exacerbation.
