Even though these firearms are categorized as toys, injuries with these are quite common in children and adolescents. The most common reason for these types of injuries is accidents and negligence. In this case report we present a 17-year-old male, admitted to the emergency department with a 5 mm incision below his left eye. In the CT imaging a pellet was seen lodged in the cribriform plate. It pierced through the ethmoid sinus. The patient was admitted to the inpatient clinic and managed conservatively with antibiotherapy. A review of literature was performed to find out the best strategy to reach an optimized outcome and evaluate probable complications.展开更多

Congenital forms develop from the remnants of the epithelium or ectodermal membranous bone growth line. We report here a case of a congenital frontal dermoid cyst that should be considered in the differential diagnosis of lipoma and neurofibroma. Dermoid cysts should be considered in the differential diagnosis of all nodular cyst-like lesions in the head and neck region. Early recognition and accurate diagnosis by means of Computerized Tomography scan or Magnetic Resonance Imaging facilitate successful treatment.展开更多

Methods: 141 cases having done transsphenoidal pituitary surgery are evaluated from 2005 to 2014. Fluoroscopy was used in 69 cases and vascular micro-doppler with neuronavigation were used in 72 cases. Results: Transsphenoidal surgery has a lot of risks due to sella’s deep location, and position of the carotid artery and the optic nerve. Clasically the fluoroscopy and microscopic anatomical markers were used in order to minimize the risk of carotid artery and optic nerve damage. Additional devices such as neuronavigation and vascular micro-doppler are needed to decrease the morbidity and mortality arising from these injuries. Conclusion: Neurovascular complications such as carotid artery and optic nerve injuries owing to disorientation in transsphenoidal surgery will reduce the use of neuronavigation with vascular micro-doppler.展开更多
