Nasoalveolar Bone Graft Integration Range in Patients with Cleft Lip and Palate Sequels

Alejandro Montaño López, Héctor Rincón Rodríguez, Carlos Landa Solís



Cleft lip and palate are  growth and development conditions accounting for 15% of congenital malformations, and are associated to external and internal factors. One of the most linked sequels to  this condition is  the nasoalveolar cleft (NAC). Treatment  for this condition is generally based on a periosteal surgery or a bone graft. These can be classified according to the age or time when they are administered, as well as to the type or nature of the material used.


To determine  bone integration extent in nasoalveolar secondary bone grafts, obtained from the iliac crest in patients with unilateral cleft  palate and lip sequels (CPLS) surgically treated following DrPhillipe Boyne`s technique, published in 1972. These patients were treated at the Maxillofacial Surgery Service of the Mexico s Children Hospial, Federico Gomez.


104 clinical and radiographic files of unilateral CPLS patients were examined. Patients age range was 7 to 14 years. Patients were  classified according to the  following criteria : gender, age, side of the cleft and development of complications. Grafts were radiographically  evaluated, height with respect to the nasal floor was determined, and grafts  were classified according to  publications by  Brusati and Garattin in 2000.


A dependence was established between the extent of bone integration and the development of complications. No other dependence was observed in any of the variables.


 In the sample of studied population, Dr Philippe Boynes technique for  reconstruction of NAC and CPLS with extirpation and application of the iliac crest was very effective since adequate amounts of bone integration were achieved.
