[Value of scaphal graft in secondary rhinoplasties].
The scaphal cartilaginous area is a most suitable anatomic site for cartilaginous graft harvesting. These grafts allow reconstruction of a flat dorsum, or a rounded dome, or alar cartilages or can be used for an extended tip graft. In some cases, both scaphes may be harvested. Raising of the grafts does not leave any sequelae when performed correctly. We have an experience of 20 cases. The main advantage of this graft is its flatness, which makes it ideal for the nasal dorsum. It has to be tailored, moderately crushed and included in a collagen "surgicel" in order to break the shape memory, slightly curved at its borders. We have used scaphal autografts in 15 cases of secondary rhinoplasties, 2 cases of cleft lip repair and in 3 cases of tertiary rhinoplasties. They solved most problems of missing cartilage, when minor defects had to be treated. These grafts will not solve major tissue defects which must be repaired by bone autografts, mostly iliac bone harvesting in our experience. The results of scaphal autografts are stable after 5 years. Resorption is moderate when the graft is correctly inserted, in an extramucosal pocket. The aesthetic result is maintained with a mean follow up of 2 years for 15 cases. The scaphal area of the ear therefore appears to be a favorable donor site for secondary, nose repair; it is easy to harvest, with inconspicuous morbidity and allows the raising of a good, flat and sculpturable material for cartilaginous nose replacement. Achieves the objectives of ore informed patients asking for artistic perfection.
