The authors reported on 10 cases of maxillary sinus cyst caused by radical sinusectomy (postoperative Wangenzyste: Kubo) encountered in 1961 and 34 other cases encountered during the two-year period of 1968 and 1969.
The greatest interval between the time of surgery and that of development of symptoms was 50 years.
The authors discussed and commented on grounds of the data upon problems in extranasal sinusectomy and reminded rhinologists of possible complications that might develop in a few decades after surgery.
