[The influence of Millard-lip-repair on maxillary growth: an experiment study in rabbits].
OBJECTIVE
To study the effects of the cheiloplasty(Millard rotation-advancement lip-repair) on the maxillary growth.


METHODS
Thirty Japanese white rabbits were randomly divided into three groups, Group I (unoperated control group), Group II (unrepaired control group) and Group III (repaired with Millard-lip-repair). All the animals were sacrificed and measured on the clean slulls directly at 26 weeks postoperatively (30 weeks old).


RESULTS
It was found that Group III (Millard repair group) had the anterioposterior growth disturbance of maxilla than Group I and II, while the height of maxilla and width of posterior dental arch were larger than that of the two control groups for compensation, and the nasal septum of Group III deviated to the cleft side.


CONCLUSIONS
Millard-rotation-advancement lip-repair operation has inhibitory effects on maxillary growth.
