Correction of major saddle nose deformities with nasomaxillary depression using an intraoral and external open rhinoplasty approach.

摘要

Nasomaxillary depression, which may be seen with major saddle nose deformities, especially as a sequel to childhood nasal trauma, generally is overlooked during management of the saddle nose. To handle both the saddle nose deformity and nasomaxillary depression, the authors used a one-stage intraoral and external open rhinoplasty approach for 12 patients. Lateral nasal osteotomies and correction of midface retrusion with crescent-shaped autogenous rib cartilage grafts were performed through two bilateral intraoral gingivobuccal incisions. The external open rhinoplasty approach was used for the correction of the saddle nose deformities. The mean follow-up period after the surgery was 2 years (range, 1-3.5 years). The correction of nasal tip depression resulting from midface retrusion was evaluated by lateral cephalometric radiographs. The mean movement of the nasal tip anteriorly in the sagittal plane 1 year after the operation was 5.5 mm (range, 4-7 mm). The functional and aesthetic results were satisfactory for all the patients. As the findings show, the intraoral part of the approach provides a route for the placement of cartilage grafts to correct the depressed nasal tip, augment the paranasal area, and provide support to the lateral alar bases and the controlled low-to-low lateral osteotomies. The external part of the approach provides correction of the saddle nose deformity.
