Surgical therapy in advanced sinonasal carcinomas - retrospective study.

Background And Aim: Sinonasal tumors are a rare and heterogeneous group of malignant tumors with different histopathological characteristics and clinical presentation. These tumors are usually treated through surgery. The aim of this study is to present our results of surgical therapy in patients with an advanced sinonasal tumor.

The use of an O-arm in endonasal endoscopic operations of the skull base.

Background: Endoscopic endonasal transsphenoidal approaches are broadly used nowadays for a vast spectrum of pathologies sited in the anterior and middle cranial fossa. The usage of neuronavigation systems (neuronavigation) in these surgeries is crucial for improving orientations deeply inside the skull and increasing patient safety.

Methods: The aim of this study was to assess the use of optical neuronavigation, together with an intraoperative O-arm O2 imaging system, in a group of patients with hypophyseal adenoma that underwent a transnasal transsphenoidal surgery, and correlate the accuracy and its deviation during the navigational process against the use of conventional neuronavigation that uses preoperative MRI and CT scans.

Pharyngeal perforation after blunt cervical trauma in child.

Pharyngeal perforation caused by non-penetrating cervical trauma is an extremely rare clinical entity both in adults and children. Data concerning management of this type of injury are quite rare in surgical and even scarcer in pediatric literature. Since delay in treatment may be associated with life-threatening complications, prompt diagnosis coupled with appropriate therapy is essential for achieving favorable clinical outcome.
