Applications of autologous vein graft in the field of oral and maxillofacial surgery

We analysed the clinical datas obtained from 10 patients who underwent reconstructive microsurgery using venous autografts(male, 9 : female, 1 : range of age, 18-70 years old). The autologous veins were used to lengthen the pedicle in 6 cases. In the rest 4 cases, we used the autologous veins to reconstruct the defect of radial artery, lacrimal canaliculi, Wharton s duct and to guide the nerve regeneration, respectively. A length of long(7 cases) or small(3 cases) saphenous veins were harvested. Various types of venous graft with long saphenous vein and its branches(Medial femoral vein and external pudendal vein) were designed, including Y-, Loop- and interpositioning-type. These designs were very helpful when there were inadequate pedicle length, unsuitable recipient vessels. We could observe the patency in the repaired Wharton s duct and lacrimal canaliculi with good salivation and lacrimal drainage. Sensory was restored with the venous tubular guide. In conlusion, venous autografting was most reliable(success rate 90%) and useful technique that might be used in the field of oral and maxillofacial surgery.
