Tumors of the skull base : extra- and intracranial surgery of skull base tumors : [based on papers presented at the 2. internat. meeting of the Skull Base Study Group, June 21-23, 1984, in Mainz, Germany

tracranial remnants of tumor, which had to be left in order to preserve important intracranial structures. ## Results From 1972-1981 fourteen patients with an angiofibroma of the nasopharynx were treated surgically. All patients were male, the ages ranging from 10-19 years. Twelve patients had tumors of size type I and II, two patients type III and IV. Twelve patients had a transpalatal, transmaxillary or a lateral rhinotomy approach. Two patients were treated by a transcervical-transmandibular approach and were given 4000 rads to the non-resected intracranial tumor remnant. No recurrence or tumor growth has been seen in any case up to the present time. Preface Contents I.

In der 1968 gegründeten Reihe erscheinen Monographien aus den Gebieten der Griechischen und Lateinischen Philologie sowie der Alten Geschichte. Die Bände weisen eine große Vielzahl von Themen auf: neben sprachlichen, textkritischen oder gattungsgeschichtlichen philologischen Untersuchungen stehen sozial-, politik-, finanz- und kulturgeschichtliche Arbeiten aus der Klassischen Antike und der Spätantike. Entscheidend für die Aufnahme ist die Qualität einer Arbeit; besonderen Wert legen die Herausgeber auf eine umfassende Heranziehung der einschlägigen Texte und Quellen und deren sorgfältige kritische Auswertung.
