Comparative survey of osteotomized and nonosteotomized BCLP patients.
OBJECTIVE
At Hannover Medical School, treatment of BCLP patients was revised and updated in 1980. The objective of the present study was to evaluate the differences in treatment outcome between BCLP patients treated after the revised concept including infant orthopedics, and BCLP patients who received osteotomy in addition to surgical and orthodontic treatment during childhood.


METHODS
Nine of 48 BCLP patients born between 1980 and 1983 received surgical and orthodontic treatment according to the Hannover concept. They were compared to 9 of 68 adolescent and adult patients from Hannover without this protocol, who underwent maxillary osteotomy and consecutive orthodontic treatment.


METHODS
Comparison of the two groups was made at the end of active orthodontic treatment by cast analysis and lateral cephalometrics to evaluate sagittal, transverse, and vertical changes.


CONCLUSIONS
No patient treated using the revised protocol showed characteristics of skeletal angle class III at any stage of investigation. No indication for osteotomy was found in this group. All patients with osteotomy had skeletal angle class III resulting from insufficient midfacial growth. Sagittal and vertical skeletal relations were successfully improved by osteotomy.
