Jjd. Vanotterloo et al., TMJ PERFORMANCE AND BEHAVIOR IN PATIENTS MORE THAN 6 YEARS AFTER LE-FORT-I OSTEOTOMY, British journal of oral & maxillofacial surgery, 31(2), 1993, pp. 83-86
Sixteen non cleft patients treated by one piece Le Fort I osteotomy we
re investigated for TMJ symptoms. Clinical examination and subjective
assessment by the patients was used over a 6-year period. No increase
in symptoms was recorded in the osteotomy group as compared to the gen
eral population, however, condylar atrophy was seen in two patients. B
oth of these patients were classified as high mandibular plane angle,
with absolute mandibular retrognathism. This suggests that this group
may be at greater risk of condylar atrophy.
