In a 5-year period, 30 titanium implants (Bowerman and Conroy 1969) were utilised for the reconstruction of mandibular defects following tumour operations. Of these, 20 implants were removed prematurely. Reasons for early removal were: 1. postoperative dehiscence of wound (5), 2. perforation through the skin or mucosa (5), 3. infection of graft bed (7), 4. breakage of the implant (1), 5. tumour recurrence (2). A total of 9 implants were retained for one or more years. The results are compared with those of Bowerman (1974). Reasons for the early loss as well as the clinical implications are discussed.

[Closing an anterior sinusal opening using lyophilized dura].

The systematic application of lyophilized dura for closing the anterior opening of the maxillary sinus after primary and revisional surgery at the maxillary antrum is reported. This method was applied in 32 primary maxillary sinus operations and in 6 revisional operations. The follow-ups showed a satisfactorily small number of postoperative complaints. This allows the conclusion that lyophilized dura is a suitable material for closing the anterior window in operations on the maxillary sinus.
