Blutungen nach CO2-laserchirurgischer Tumorentfernung im HNO-Bereich

Background: There are different reports in the literature how often postoperative hemorrhage occurs after laser resection of head-and-neck tumours. This retrospective study investigates the frequency of postoperative hemorrhage after laser surgery of head and neck tumours. Time and extent of bleeding have been considered as well as the localization of the primary tumour and possible general risk factors. Methods and Patients: Between 1998 and 2001, microscopic laser surgery was performed in 223 patients with previously untreated squamous cell carcinomas of the oral cavity, oropharynx, supraglottic and glottic region and the hypopharynx. In case of ultrasonographic or palpable evidence of ce…

Ungewöhnlicher Verlauf von otobasalen Frakturen mit Liquorrhoe*

In the literature the persistence of cerebrospinal Liquorrhea after temporal bone fractures is a rare event. Between 1989 and 1992 four cases of temporal bone fractures with dural involvement were operated at the University ENT Department Mainz. These temporal bone fractures showed delayed or persistent symptoms of dural lacerations between three and sixty months after head injury. During operation we found larger bone-dura defects (1-1.5 cm in diameter) and brain herniations in all cases. Strohm stated that only in rare cases a temporal bone fracture produced a larger gap in the tegmen tympani or antri. Therefore, we assumed that in our cases such larger bone-dura defects were caused by a …

Arachnoidalzyste der Keilbeinhöhle

BACKGROUND Arachnoid cysts of the paranasal sinus are rare. They have not been described yet in the sphenoid sinus. PATIENT AND METHOD Microscopic-endoscopic endonasal surgery of the sphenoid sinus was performed on a 34-year-old female with a history of chronic headaches and a suspected mucocele of the sphenoid sinus in computed tomography (CT) and magnetic resonance imaging (MRI) studies. An extended arachnoid cyst was found in the enlarged sphenoid sinus, which was obliterated with collagen, fibrin glue, and abdominal fat. RESULTS There were no complications after the operation, and 12 months later the patient is still free of symptoms. CONCLUSION Arachnoidal cysts present in CT and MRI a…
