Endoscopic Endonasal Approach to the Third Ventricle Using the Surgical Corridor of the Reverse Third Ventriculostomy: Anatomo-Surgical Nuances.

INTRODUCTION AND

OBJECTIVE

Alveolar cleft is present in 75% of cleft patients. Alveolar bone grafting can be divided according to time of the procedure into primary, early secondary, secondary and tertiary.

MATERIAL AND

METHODS

A retrospective analysis of 41 children with early secondary alveolar bone grafting was performed. Qualification for autologous bone grafting (ABG) was performed during orthodontic consultation. The presence of a symptomatic oronasal fistula and/or a bone defect within the alveolar process that could hinder orthodontic treatment and prosthetic rehabilitation in the cleft area was also assessed. Prior to the procedure, a dental examination was required, and, if necessary, treatment of carious lesions or inflammatory conditions within the oral cavity completed. In children over the age of 5, qualification for surgery was based on an orthodontic assessment of Cone Beam Computed Tomography (CBCT) imaging of the cleft area.

RESULTS

Early secondary autologous bone grafting (eSABG) was carried out in 7 children with cleft lip (3 with left-sided cleft lip, 2 with right-sided cleft lip, and 2 with bilateral cleft lip) and in 34 children with cleft lip and palate (20 with left- sided cleft lip and palate, 8 with right-sided cleft lip and palate, and 6 with bilateral cleft lip and palate). In 1 case, loss of bone graft was observed. No other serious complications were reported.

CONCLUSIONS

The results suggest that early secondary alveolar bone grafting using iliac crest bone in alveolar cleft associated with cleft lip or cleft palate, is a safe procedure with a low rate of serious complications.
