Abstract:
Modified condylotomi
The modified condylotomi is an ekstra-articular surgical procedure used to manage patients with
temporomandibular joint dysfunction. I will go through the procedure and tell you about the patients we
have been treated in Aalborg.

Abstract
Long-term follow-up on total reconstruction of the temporomandibular joint - functional,
psychosocial and radiological assessments in a case-series study.

This case-series included seven subjects who had total joint reconstruction with Biomet® Total
Temporomandibular Joint (TMJ) Replacement System at Department of Oral and Maxillofacial
Surgery, Aarhus University Hospital. The follow-up examination included a functional, psychosocial
and radiological examination. The functional assessment was conducted according to the Research
Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). The radiological assessment
involved a cone beam computed tomography (CBCT) (NewTom, USA). Oral health impact on quality
of life was assessed by the Danish version of the Oral Health Impact Profile questionnaire (OHIP).
Results: The prostheses were placed in average six years before the follow-up examination (range 4-9
years). The range of mandibular movement was low in all directions. According to the RDC-TMD
algorithm four subjects had myofacial pain. Two patients had a high chronic pain disability and three
patients had a low disability. Patients with TMD disability had a high impact of oral health on quality of
life for the sub-domains functional limitation, physical pain and physical disability. Heterotopic bone
formation on the medial aspect of the reconstruction was observed in 8 out of 12 TMJ-reconstructions.
Conclusion: This case-series study showed a 100 per cent survival rate of Biomet® Total
Temporomandibular Joint (TMJ) Replacement System after six years of observation. A high occurrence
of heterotopic bone formation on the medial aspect of the prostheses was observed. Furthermore, some
patients had a chronic pain disability, low range of mandibular movement and impact of oral health on
quality of life. Further studies are needed.
