BACKGROUND: A pneumocele occurs when an aerated cranial cavity pathologically expands; a pneumatocele occurs when air extends from an aerated cavity into adjacent soft tissues forming a secondary cavity. Both pathologies are extremely rare with relation to the mastoid. This paper describes a case of a mastoid pneumocele that caused hypoglossal nerve palsy and an intracranial pneumatocele. CASE REPORT: A 46-year-old man presented, following minor head trauma, with hypoglossal nerve palsy secondary to a fracture through the hypoglossal canal...

Fibromuscular dysplasia (FMD) is a rare, segmental, nonatheromatous, and noninflammatory arterial disease of unknown etiology. It predominantly involves renal artery (60-75%) followed by extracranial part of the internal carotid artery and vertebral arteries (25-30%). The disease typically affects middle-aged women and involves intermediate-sized arteries throughout the body. There are rare case reports of extracranial FMD compounding a trauma case. A patient was brought to trauma center emergency with a history of fall from height...

Spontaneous epidural pneumocephalus is a rare condition. The authors reported a 35-year-old male patient with tinnutus, dull headache, and swelling on his head. Patient had a history of head trauma and skull fracture from when he was 5 years old. Cranial computed tomography revealed increase in pneumatization of right mastoid air cells and large epidural air in temporoparietal region. Inner table of right temporal bone got thinner, causing communication of mastoid air cells with epidural space. Epidural air had septations and exerted mass effect on the right parietal lobe with minimal midline shift...

A 36-year-old man was brought to the emergency department by emergency medical services after being found acting unusually at a gas station with blood on his head and clothing. He presented acutely psychotic and reported that he had a pen in his head. Medical evaluation was notable for a superficial puncture wound to the right temple, and he was medically cleared for psychiatric evaluation. After he developed nausea and headache later that evening, the CT scan revealed a temporal bone fracture, pneumocephalus, intraparenchymal haemorrhage and the presence of a metal pen tip lodged in the brain parenchyma...

We report a case of a 7-year-old child with a cranial deformity secondary to a craniotomy for an intracranial hematoma. He suffered from an acute epidural hematoma with a lineal fracture of the right temporal bone following a severe head injury. A large question mark-shaped skin flap with the periosteum and temporal muscle was created for a decompressive craniectomy; however, neither the acute epidural hematoma nor brain swelling was severe, and we performed a small craniotomy compared with the skin flap without a decompressive craniectomy...

Temporal bone fractures can occur as a result of various head trauma. The most common cause of the hemotympanum is traumatic temporal bone fracture. Facial paralysis and hearing loss can be seen associated with temporal bone fracture. The development of the internal carotid artery aneurysm after temporal bone fracture is extremely rare. In this article, the authors evaluated carotid artery aneurysm that developed after temporal fracture and aneurism compressed by coagulated blood mass which showed itself as a hemotympanum...

Cochlear implant (CI) is an artificial electronic device which can provide a sense of sound to a patient with severe or profound hearing loss. Pathological changes have been observed after CI surgery, which might influence the effectiveness of the CI procedure. In this review, we divided the postoperative pathological changes of the temporal bone into two categories according to different stages: immediate trauma and delayed side effects. Immediate trauma might arise from traumatic insertion of the electrode during CI surgery, which included trauma at cochleostomy site, lateral wall trauma, basilar membrane injury, osseous lamina fracture and modiolar injury...

Introduction. Labyrinthine concussion is a term used to describe a rare cause of sensorineural hearing loss with or without vestibular symptoms occurring after head trauma. Isolated damage to the inner ear without involving the vestibular organ would be designated as a cochlear labyrinthine concussion. Hearing loss is not a rare finding in head trauma that involves petrous bone fractures. Nevertheless it generally occurs ipsilateral to the side of the head injury and extraordinarily in the contralateral side and moreover without the presence of a fracture...

Body composition and muscle function have important implications for falls and fractures in older adults. We aimed to investigate longitudinal associations between sarcopenic obesity and its components with bone mineral density (BMD), and incident falls and fractures, in Australian community-dwelling older men. 1,486 men aged ≥70 years from the Concord Health and Ageing in Men Project (CHAMP) study were assessed at baseline (2005-2007), 2 year follow-up (2007-2009; N = 1,238), and 5 year follow-up (2010-2013; N = 861)...

Bone fracture healing is processed through multiple biological stages including the transition from cartilaginous callus to bony callus formation. Because of its specific, temporal and indispensable functions demonstrated by mouse genetic studies, Hedgehog (Hh) signaling is one of the most potent signaling pathways involved in these processes, but the effect of Hh-signaling activation by small compounds on the repair process had not yet been addressed. Here we examined therapeutic effects of local and one shot-administration of the Hh agonist known as smoothened agonist (SAG) on bone fracture healing in a mouse model...

INTRODUCTION: Although bilateral facial nerve palsy is a rare condition, its etiology is more detectable than the unilateral type. A temporal bone fracture is one cause of bilateral facial nerve palsy, contributing in 3% of the cases. CASE PRESENTATION: Here, we report the case of a 35-year-old man complaining of bilateral incomplete eye closure, two weeks after a closed head injury caused by a motor vehicle accident. CONCLUSIONS: The high resolution computed tomography findings revealed a bilateral temporal bone fracture line, which extended to the fallopian canal...

Because changes in the mechanical properties of bone are closely related to trabecular bone remodeling, methods that consider the temporal morphological changes induced by adaptive remodeling of trabecular bone are needed to estimate long-term fracture risk and bone quality in osteoporosis. We simulated bone remodeling using simplified and pig trabecular bone models and estimated the morphology of healthy and osteoporotic cases. We then displayed the fracture risk of the remodeled models based on a cumulative histogram from high stress...

REVIEW
Rodney C Diaz, Brian Cervenka, Hilary A Brodie
Traumatic injury to the temporal bone can lead to significant morbidity or mortality and knowledge of the pertinent anatomy, pathophysiology of injury, and appropriate management strategies is critical for successful recovery and rehabilitation of such injured patients. Most temporal bone fractures are caused by motor vehicle accidents. Temporal bone fractures are best classified as either otic capsule sparing or otic capsule disrupting-type fractures, as such classification correlates well with risk of concomitant functional complications...

BACKGROUND: Resection of cranial tumors involving both bone and scalp tissue may require the recruitment of soft tissue using a flap above the bone reconstruction. When a transposition flap has been chosen, the alopecia zone on the donor site may be difficult to treat afterward. Scalp expansion is the gold standard in these situations, but this has never been described above cranial implants. We report the first case of a patient who underwent a scalp tissue expansion above a custom-made hydroxyapatite cranial implant to correct sequelar alopecia...
