[Calcium phosphates in surgery of the middle ear. I. The concepts and definitions].
The techniques which pursue the closure of radical cavities include the use of local flaps as well as alloplastic material. Calcium phosphates are classified as "degradable" or "not degradable". The paper tries to offer an explanation why hydroxyapatite or tricalcium phosphate, mostly used calcium phosphates, may be include in both groups. The introduction in the use of alloplastic materials should serve as orientation for those who initiate and stimulate to revision of clinical results. The comparison of same calcium phosphates seems not to be possible as their preparation techniques may be completely different.
