title: Changing the convexity and concavity of nasal cartilages and cartilage grafts with horizontal mattress sutures: part II. Clinical results.
abstract: Horizontal mattress sutures have previously been shown to remove unwanted bulbosity and convexity of nasal tip cartilages. The purpose of this study was to extend that concept by investigating the universal applicability of the horizontal mattress suture to change and control the curvature (e.g., convexity or concavity) of a wide variety of nasal cartilages and warped cartilage grafts. The horizontal mattress suture was applied to a variety of clinical situations, including nasal tip bulbosity caused by convex lateral crura, collapsed external nasal valves, warped grafts and struts, crooked L-shaped septal struts, and collapsed internal nasal valves. Twenty-nine cases were studied over a period of 10 to 23 months. The horizontal mattress suture proved to be a simple, effective means of achieving satisfactory control of the curvature of various cartilages of the nose (including external valves, internal valves, and septum) and warped cartilage grafts. Curvature control was obtained in all cases where the cartilage was supple. Moreover, the resultant strength was increased above normal. Partial recurrence of the curvature was seen in only two cases. Clinical results indicated that the horizontal mattress suture is universally applicable to a variety of situations in which the curvature of nasal cartilage and cartilage grafts needs to be removed or modified. The mattress suture drastically reduces the need for scoring (with its inherent problems of weakness) and the need for cartilage grafting.
