Abstract

Hyperventilation syndrome is primary hyperventilation producing respiratory alkalosis associated with highly variable and impressive array of signs and symptoms. Typical features are tachypnea, paresthesia, carpopedal spasm, tetany, chest pain and dizziness. Rebreathing into a paper or vinyl bag will reverse the alkalosis-induced symptoms and help the patient calm down. We report hyperventilation syndrome associated with extraction of mandibular third molar and describe the physiology and treatment. Accidental displacement of mandibular third molars is rarely reported complication. Most common anatomic structures of dislodgement are submandibular space, lateral pharyngeal space and pterygomandibular space. This report describe an unusual case of two roots of mandibular third molar that were displaced into submandibular space.
