Wenming Wang, Hua Liu, Jian Yang, Yafang Shen
Disseminated intravascular coagulation (DIC) developing after cranioplasty, a skull reconstructive surgical procedure, is very rare. The presently reported patient underwent cranioplasty for cranial trauma under general anaesthesia using titanium prostheses. Her laboratory data was unremarkable. She underwent three operations, each complicated by excessive postoperative bleeding. Although the patient received massive blood transfusions, but no cryoprecipitate coagulum was given during the first two re-operations, and excessive bleeding was evident...

BACKGROUND: Cranial and oral-maxillofacial injuries accounted for 33% of military visits to in-theater (Level III) military treatment facilities for battle injuries during Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF). Even after years of conflict, the size and scope of oral-maxillofacial injuries in military armed conflict is still not fully understood. This study reports U.S. Department of Defense (DoD) rates of oral-maxillofacial injuries that can be used for further surveillance and research...

Isolated third nerve palsy develops in numerous intracranial pathologies such as closed head trauma, tumor, and aneurysm. This report describes a 61 years old female with an abrasion on the left forehead and ptosis of the left eye. Initial computed tomography did not reveal any causative cerebral and vascular lesions or orbital and cranial fractures. High-resolution and multi-axial enhanced Magnetic resonance imaging (MRI) can be helpful in diagnosis and monitoring of patients with this rare phenomenon.

BACKGROUND: Spontaneous intracranial hypotension is a rarely diagnosed cause of headache, especially in children and adolescents. It is due to cerebrospinal fluid (CSF) leakage via spinal fistulae occurring without major trauma. CASE PRESENTATION: An adolescent patient presented with a 3-month history of strictly postural headache. Cranial magnetic resonance imaging (MRI) showed pronounced Chiari-like prolapse of the cerebellar tonsils, narrow ventricles and enlarged cerebral veins...

Linear skull fracture, following head trauma, may reach major blood vessels, such as the middle meningeal artery or sinus venosus, and may cause epidural hematoma. However, hematoma is likely to be missed in the initial interpretation because it spreads only gradually. In addition, the fracture lines that run along the scan slice plane are often missed during initial interpretation. In this study, we develop a novel method for automated detection of the linear skull fracture using head computed tomography (CT) images and conduct a basic evaluation using digital phantom and head phantom that enclose genuine human bones...

Large skeletal defects caused by trauma, congenital malformations, and post-oncologic resections of the calvarium present major challenges to the reconstructive surgeon. We previously identified BMP-9 as the most osteogenic BMP in vitro and in vivo. Here we sought to investigate the bone regenerative capacity of murine-derived calvarial mesenchymal progenitor cells (iCALs) transduced by BMP-9 in the context of healing critical-sized calvarial defects. To accomplish this, the transduced cells were delivered to the defect site within a thermoresponsive biodegradable scaffold consisting of poly(polyethylene glycol citrate-co-N-isopropylacrylamide mixed with gelatin (PPCN-g)...

Isolated unilateral abducens nerve palsy is usually due to ischemia, trauma or neoplasm. Dorello's canal is the space between the petrous apex and superolateral portion of the clivus, bound superiorly by Gruber's ligament. The abducens nerve travels with inferior petrosal sinus (IPS) though the Dorello's canal before entering the cavernous sinus. A 31-year-old man presented with neck pain, and binocular horizontal diplopia, worse looking towards left and at distance. He had a history of intravenous drug abuse but no history of hypertension or diabetes...

Biparietal thinning resulting in bilateral and symmetrical resorption and loss of thickness of the parietal bones is an uncommon to rare condition in the anthropological and clinical literature. This enigmatic condition of unknown etiology was first reported in the 18th century and has been variously described as a nonmetric trait, anatomical variant, anomaly, and pathology. Biparietal thinning presents grossly and radiographically as oval-shaped depressions in 0.25-0.8% and 0.4-0.5% of individuals and with a higher frequency in females over the age of 60 years...

Metastases in the paranasal sinuses are rare; renal cell carcinoma is the most common cancer that metastasizes to this region. We present the case of a patient with a 4-month history of a rapidly growing mass of the nasal pyramid following a nasal trauma, associated with spontaneous epistaxis and multiple episodes of hematuria. Cranial CT scan and MRI showed an ethmoid mass extending to the choanal region, the right orbit, and the right frontal sinus with an initial intracranial extension. Patient underwent surgery with a trans-sinusal frontal approach using a bicoronal incision combined with an anterior midfacial degloving; histological exam was compatible with a metastasis of clear cell renal cell carcinoma...

BACKGROUND: The causes of craniovertebral junction (CVJ) instabilities include trauma, rheumatological diseases, tumors, infections, congenital malformations, and degenerative disease processes; these complex pathologies often require CVJ instrumentation. Hardware complications were analyzed in a personal series of 48 treated patients. In light of the analysis of very unusual radiological and clinical findings, the authors tried to better investigate the related mechanisms and to reach possible useful conclusions...

Reconstruction of a midfacial defect can represent a difficult challenge for the plastic surgeon. Although many midfacial deformities have traumatic or congenital origins, the vast majority of head and neck defects occur after resection of malignant head and neck neoplasms. Autogenous reconstruction is now routinely performed for larger, complex defects resulting from surgical resection or trauma. In this study, the authors present 27 patients with midfacial defects reconstructed with free flaps. Twenty-two of the defects were created by surgical ablation of cancer (maxillectomy) and the others were traumatic...

Hirschsprung disease is a congenital disease characterized by intestinal aganglionosis of various extents. Most patients are younger than 1 year of age. Though, a minority of cases can be older or even adult. Older the patient the more difficult and prolonged is the endorectal dissection required for the pull-through procedure. Longer surgery leads to longer anal dilatation and trauma with subsequent higher likelihood of continence impairment. The article aims at describing the first case series of robot-assisted Soave procedure, which was adopted as an alternative minimally invasive approach to older patients with Hirschsprung disease...

Identifying the site of vascular bleeding in fatal cases of traumatic basal subarachnoid hemorrhage (TBSAH) is important, but can be very difficult to achieve when there is extensive blood clot in the posterior cranial fossa. Post mortem angiography in these circumstances has been reported previously but with mixed results, and is rarely used in current practice within the United Kingdom. We have developed a simple and effective post mortem angiography method, using fluoroscopy and clear modern contrast medium, suitable for use in the autopsy room...

During bronchoscopically guided percutaneous dilatational tracheostomy, a 71-year-old woman suffered a long-stretched tear to the posterior tracheal wall. The injury was suspected to be caused by blunt trauma during dilation or cannula insertion, possibly aggravated by vigorous cuff inflation. Since the defect ended just 0.5 cm proximal to the main carina, placing a cuffed endotracheal tube beyond the injury was not an option. However, we decided for a conservative treatment approach by placing a cuffed endotracheal tube under bronchoscopic visualization in direct proximity to the cranial end of the laceration...

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...

BACKGROUND: The objective of this study was to assess and compare ventricle diameters in patients after decompressive craniectomy by using cranial computed tomography (CCT) versus sonographic duplex technique (SDT). METHODS: A total of 102 consecutive patients after decompressive craniectomy following brain infarct, bleeding and trauma were examined by CCT and SDT. SDT was performed within 24 h after repeated postinterventional control CCT and the correlation between both methods was assessed via measurement of dimensions of all four ventricles...

Correction of orbito-frontal defects involves a multitude of surgical challenges, and requires careful and detailed planning. In the trauma setting, one must be prepared to deal with injuries to adjacent structures and be able to incorporate their repair into the surgical plan to maximize the functional and esthetic reconstruction for the benefit of the patient. Victims who have sustained trauma of the cranial complex in combination with mid-facial trauma, particularly involving the orbit, present a difficult scenario, especially when future ocular prosthetic rehabilitation is a concern...
