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.
