Succinylcholine induced Masseter spasm in a young male with frontal sinus abscess

We report a case of frontal sinus abscess posted for FESS, a chronic ghutka chewer with MPC IV and restricted mouth opening. Following induction with propofol and succinylcholine we noticed lockjaw when intubation was attempted, he was ventilated and anesthesia was deepened using propofol and dexmedetomidine, after a few minutes the masseter spasm had improved and miller’s blade was used for endo tracheal intubation & the procedure was uneventful.
