Initial Manifestation of Acquired Hemophilia A After a Routine Tooth Extraction. A Case Report and Literature Review.

Although surgical treatment of patients on anticoagulation regimens is common practice among oral and maxillofacial surgeons, unexpected and unknown coagulopathies can have devastating and catastrophic consequences for the most routine of procedures. Acquired hemophilia A (AHA) is an extremely rare life-threatening bleeding disorder characterized by autoantibodies directed against circulating coagulation factor VIII. The effects of AHA can produce catastrophic bleeding and hematomas. The effect of this uncontrolled hemorrhage after dentoalveolar surgery can mimic severe head and neck infection by causing dysphagia, odynophagia, and acute airway complications. This report describes the case of a 64-year-old woman who was diagnosed with AHA after routine extraction of the mandibular left third molar.

Intracranial Approach for Retrieval of the Condylar Head After Avulsion into the Middle Cranial Fossa.

BACKGROUND: Dislocation of the mandibular condyle into the middle cranial fossa is a rare injury that can be seen after facial trauma. Early identification of condyle dislocation into the middle cranial fossa was difficult until the development of computed tomography, and diagnosis was often significantly delayed after the initial trauma. CASE DESCRIPTION: We present a rare case of a young woman who presents after a mechanical fall resulting in facial trauma with an avulsion condyle fracture with dislocation of the mandibular condyle into the middle cranial fossa. CONCLUSIONS: To our knowledge, this complete avulsion of the condyle into the middle cranial fossa requiring an intracranial approach for condylectomy is extremely rare. We discuss the surgical management options for reduction and fixation accomplished in a multidisciplinary approach involving neurosurgery and oral maxillofacial surgery.
