Sagittal split advancement osteotomy: comparison of the tendency to relapse after two different methods of rigid fixation.

Mandibular advancement was studied in 32 patients with mandibular retrognathia in whom the only intervention was in the mandible. Fifteen patients were treated with fixation by lag screws and 17 with monocortical miniplates. Lateral radiographs were taken preoperatively, postoperatively, 2 months postoperatively, and 1.

Unrepaired clefts in the hard palate: speech deficits at the ages of 5 and 7 years and their relationship to size of the cleft.

The purpose of the study was to investigate the relationship between the size of oronasal openings in the hard palate and speech deficits. Audiotape recordings and plaster casts were taken according to standard procedures at 5 and 7 years of age from 22 consecutive children born with complete unilateral cleft lip and palate treated at Sahlgrenska University Hospital, Göteborg, Sweden. The soft palate had been repaired before the age of 12 months, whereas the cleft in the hard palate was left unrepaired, to be closed later.
