Nasal reconstruction with full-thickness cranial bone grafts and rigid internal skeleton fixation through a coronal incision.

The use of iliac and rib bone as onlay grafts to the nasal dorsum often fails because endochondral grafts resorb unpredictably. Membranous cranial bone grafts are less likely to resorb, especially when used with rigid internal fixation techniques. However, when split, they are often too thin and can be difficult to contour. Full-thickness cranial bone grafts were used to achieve nasal augmentation in 26 patients with end-stage nasal skeleton deficiency. All procedures were carried out using only a coronal incision. Grafts were harvested through a craniotomy, carved meticulously, and secured rigidly with miniplates or bicortical screws. Donor sites were reconstructed with split cranial grafts, leaving an intact cranial vault. No graft was lost to infection, and there was no significant donor-site morbidity. In carefully selected patients this method of full-thickness cranial bone graft reconstruction yields good results.
