Posttraumatic Temporal Bone Meningocele Presenting as a Cystic Mass in the External Auditory Canal.

Introduction: Temporal bone meningoencephalic herniation may occur in head trauma. It is a rare condition with potentially dangerous complications. Several different routes for temporal bone meningoencephalocele have been proposed.

Cutaneous Metaplastic Synovial Cyst: A Case Report and Literature Review.

Introduction: Cutaneous metaplastic synovial cyst (CMSC) is a rare cutaneous lesion characterized by a tender subcutaneous nodule, which usually occurs at the site of previous surgical or local trauma. Histologically, the lesion includes a cystic structure with villous-like projections and a lining mimicking hyperplastic synovium.

Case Presentation: We reported the first case of CMSC which developed at the surgical incision site of treatment of a maxillofacial fracture.

Comprehensive treatment and rehabilitation of a patient with maxillary arteriovenous malformation.

Arteriovenous malformations (AVMs) of the maxilla are rare and potentially life-threatening conditions that can pose a therapeutic dilemma. We reported the first case of maxillary AVM in a 15-year-old girl who was treated by marginal hemimaxillectomy including overlying palatal mucosa and immediate replantation of the segment after removing the AVM tissues and teeth and covering by a full-thickness pedicled temporal muscle flap rotated into the mouth. Then, this preserved bone underwent distraction osteogenesis and dental implant rehabilitation successfully.

Intracranial meningioma at the site of a previous cranial penetrating trauma due to shrapnel.

Meningiomas are common and mostly benign intracranial tumors, which originate from arachnoid cells of the meninges, and account for approximately 25% of all primary intracranial tumors. Many external etiological factors have been described as etiology of meningioma in the literature, one of which is head trauma. However, trauma as a cause of meningioma remains a controversial subject.

Pseudoaneurysm of the superficial temporal artery following penetrating trauma.

Pseudoaneurysm of superficial temporal artery (STA) is an uncommon complication of blunt and penetrating trauma. It accounts for only 1% of all traumatic aneurysms. Most pseudoaneurysms of STA present as a painless pulsating mass, and its diagnosis can be made with physical examination and ultrasound or computed tomography angiogram.
