Cephalometric radiographs and dental study casts were analyzed in a group of 23 seven-year-old cleft lip and palate patients, 16 with unilateral and 7 with bilateral cleft. The patients' primary surgical procedures had been completed except for closure of the cleft in the hard palate. For comparison, similar records from another group of patients, 18 with(More)
The development of the face and jaws in cleft patients, treated with a three-stage surgical procedure including a single layer vomer flap, was studied by analysing cephalometric radiographs and dental casts. The material consisted of 13 patients with complete bilateral cleft lip and palate and 50 cases with complete unilateral cleft lip and palate, operated(More)
Our results of bone grafting to the alveolar process during the mixed dentition were investigated in 55 consecutively treated patients (66 clefts). The amount of remaining bone and gingival retraction at the tooth mesial to the cleft after 3 and 12 months was measured and correlated with the following anatomical conditions present during surgery: width of(More)
A new routine for the surgical treatment of cleft lip and palate patients is presented. Beside the regular lip-nose surgery it includes delayed closure of the cleft in the hard palate and soft palate closure without push-back technique. The effect on early facial growth was evaluated by comparing eight of these patients, three years of age, with a matched(More)
A new method was developed to evaluate more objectively the morphology of the soft tissue lip and nose after treatment of the unilateral cleft lip and palate deformity. Plaster casts of the mid-face of the patients were analysed by use of angular, linear and surface measurements. Thirty cases were studied 4--10 years after the primary surgery of the lip,(More)
The oblique sliding osteotomy has been used for surgical correction of mandibular prognathism, sometimes in combination with open bite, in 112 patients treated from 1969 to 1978. The method has proved to be connected with few surgical complications and minimal relapse tendency. No correlation was found between the degree of posterior positioning or closure(More)
During a ten-year period 17 patients with total congenital absence of the vagina were treated by a split-skin inlay grafting technique. The average age at the time of operation was 21 years. Associated malformations, mostly afflicting the urinary tract, were found in 9 patients. The skin graft was applied on a perforated hollow acrylic mould, 12 cm long and(More)
