Nasal reconstruction using split calvarial grafts.

Abstract

The reconstruction of nasal deformities after trauma or surgical procedures presents an arduous task for the reconstructive surgeon. The anatomic alteration of supporting cartilage and nasal bones, as well as scar formation, compound the difficult nature of this type of reconstruction. In the past, multiple autogenous and alloplastic implants have been used in nasal reconstruction. Autogenous implants include auricular and septal cartilage as well as rib and iliac crest bone grafts. Alloplastic materials include acrylic, supramid mesh, Gortex, and silicone rubber. Autogenous grafts have been shown to provide excellent long-term reliable results in nasal reconstruction. In our study, autogenous split calvarial bone grafts were used in the nasal reconstruction of 17 patients. Among the corrective procedures were dorsal augmentation for saddle-nose deformities, insertion of columella struts for nasal tip ptosis, and insertion of nasal battens for nasal valve collapse. Patient followup has been from 1 to 5 years, with no significant resorption noted during that time. Complications were limited to one seroma at the donor site before wound drains were routinely used. No major complications, including hematoma formation, CSF leak, or infection, have been observed.
