The primary gingivoperiosteoplasty by Millard consists of presurgical active orthognathic treatment ('Latham device') of the alveolar margins at the age of 3 months and of surgical closure of the @entity2419 with @entity2631 at the age of 5 months. The aim of this investigation was to analyse the facial growth following this treatment. The following material was studied: lateral head X-rays and plaster casts from 146 @entity1 with unilateral (UCLP) and bilateral ( @entity25346 ) clefts of lip and palate from birth to 16 years of age. Ninety-one of these @entity1 formed the control group, who received neither gingivoperiosteoplasty nor pre-surgical active orthognathic treatment. The same surgeon and orthodontist treated all 146 @entity1 . A three-dimensional growth disturbance after gingivoperiosteoplasty was observed: 42% @entity1 with UCLP and 40% @entity1 with @entity25346 had an 'open bite' following closure of the @entity2419 (control group 5%/10%). The length of the upper jaw in @entity1 who underwent gingivoperiosteoplasty was shorter than in the control group. The frequency of posterior cross bite was also higher in the gingivoperiosteoplasty group. These results demonstrate that treatment with a 'Latham device' disturbs facial growth. Therefore, this treatment should be abandoned.
