Histology of Condyles in Mandibular Growth Anomalies

  • Hugo L. Obwegeser


A survey of the presented cases discloses the marked variability of most types of mandibular growth anomalies, not only with respect to clinical appearance, but also regarding age at onset, duration and age at surgical intervention. Thus, in cases of condylar hyperactivity, i.e., H.H., H.E. and hybrid forms, growth can apparently turn abnormal during the regular growth period, continue beyond the age of regular growth cessation or resume activity during adulthood. Depending on the interval between the start of the disorder and condylectomy, some of the resected condyles may have been growing actively, while in others growth may have ceased. The questions we hoped would be answered by the histological examination were therefore:
  1. 1.

    Was condylar growth still going on at the time of surgery?

  2. 2.

    Did it proceed at a normal rate?

  3. 3.

    Was the mechanism of growth normal?

  4. 4.

    Is there any relationship between the structure of the condyle and the clinical picture of the growth disorder?
