Abstract
Glanzmanns thrombasthenia is a rare congenital platelet disorder characterized by prolonged bleeding time, qualitative platelet defect and severe hemorrhagic episods. we experienced 4 wisdom teeth extraction of the patient with Glanzmanns thrombasthenia. The patient was a 25-year-old female complained of pain at the lower left third molar region. The upper third molars were fully erupted but were inclined to the buccal side. The lower third molars were horizontally impacted. We first extracted the left lower and upper third molars simultaneously after platelet transfusion, and we observed no bleedings after the extraction. Next we extracted the right lower and upper third molars under the same conditions. Some authers reported that because platelet transfusion may have risks of causing hepatitis, HLA antigen products and graft versus host disease, platelet transfusion should be omitted for tooth extraction. However, in the cases expecting some surgical stress, enough pre-and post-operative platelet transfusion must be necessary to avoid post operative bleedings completely.
