Abstract

Dorsal preservation rhinoplasty in cases of a convex or overprojected noses has significant advantages over resection and reconstruction of the dorsum. Analysis of the subdorsal septum in relation to the radix osteotomy to achieve a drop or hinge of the natural dorsum is important in avoiding possible complications involving the skull base, frontal sinus, and subsequent radix position. In the majority of patients, simple cut release of the perpendicular plate rather than resection superiorly may be necessary where the quadrangular cartilage junction with the perpendicular plate is caudal to the radix osteotomy. Computed tomography is helpful in delineating this position as well as providing information on the frontal sinus and position of the cribriform plate prerhinoplasty.
