Osteoradionecrosis of the jaws.

In 431 patients treated for malignant tumors 21 osteoradionecroses (ORN) were diagnosed in 19 patients. The relation of ORN to radiotherapeutic factors and surgical as well as extraction schemes were studied. There was a clear relation to high dose, high CRE and superfraction.

[Radiotherapy of supraglottic cancers. Report on 84 patients].

Ten of 84 supraglottic carcinomas were treated by primary surgery, 32 by pre or post operative irradiation and 41 by primary irradiation and salvage surgery if recurrence developed. A comparison of the treatment results between these groups is not possible because of the lack of randomization. After follow up of 4.

[Radiotherapy of cancer of the vocal cords. Report on 287 patients].

Therapeutic results in 287 glottic and subglottic carcinomas stage I-IV are reported. After primary irradiation and salvage surgery of recurrences the actuarial 10 year-NED probability for tumours with normal mobility of the vocal cords was 78%, for those with impaired mobility it was 60% and for tumours with complete fixation in stage III it was only 27%. The relative actuarial 10 year-survival probability of the same groups were 96%, 82% and 35%.
