RESUMO
BACKGROUND: The concept of Distraction Osteogenesis is applied in Maxillofacial surgery extensively in the recent past, revolutionizing the concept of management of facial deformities specially the mandible. METHODS: This article describes intra oral mandibular distractors in managing mandibular deformities in 9 cases. CONCLUSION: Surgical intervention is possible in very young patients. Distraction Osteogenosis does not reduce the need for orthodontic intervention. A multifarious approach to the problem, should form the basis of treatment of mandibular deformities.
RESUMO
Transverse maxillary deficiencies are a common occurance, prevalent in both syndromic and non syndromic patients. Treatment usually combines a orthodontic-surgical intervention in adults. This article reviews the procedures along with the experience of the authors in the correction of maxillary transverse deficiency in adults.
RESUMO
A wide variety of disease processes produce alteration of midfacial skeletal growth, resulting in moderate-to-severe midface deficiency presenting as retrusion associated with Angle's class III malocclusion. Most cases of midface deficiency are seen in patients of cleft lip/palate. The surgical procedure to correct the clefts, undertaken over a long period of time from infancy to the teens tends to take its toll on the soft tissues over the midface. The scarring that is a feature in these conditions results in hampering of normal growth of the midface causing the deformity. Conventional procedures to correct the deformity by surgical advancement have been less than satisfactory in terms of success. This is where the concept of multidimensional growth using distraction proved useful. Today distraction has proved to be a versatile tool in the correction of midface deficiencies due to its various advantages. Six patients of cleft lip/palate were taken up for advancement of the hypoplastic midface using intra-oral distractors with successful and stable results.
