Introduction:
The saddle nose deformity is easily recognized by the loss of septal support and nasal dorsal height with adverse functional and aesthetic consequences.
Technique:
We treated a 50-year-old woman and a 54-year old man that presented with a moderate saddle nose deformity following a previous septorhinoplasty (female patient) and a posttraumatic severe saddle nose deformity (male patient). The patients were treated by open approach rhinoplasty under general anesthesia, and the saddle nose deformity was reconstructed with a semilunar conchal cartilage graft. A semilunar part of the conchal cartilage is excised, lending its name to the graft. A smaller leaf shaped cartilage part is excised and sutured upside-down with PDS 5-0 sutures on the opposite of the cartilage, so that the concave surfaces are facing each other. The newly formed graft is then sutured in its place on the nasal dorsum in the supratip saddle area over the triangular cartilages to widen the inner nasal valve angle. The lateral tips of the semilunar graft are placed below the lateral alar crura to improve external nasal valve functionality.
Discussion:
This modified conchal cartilage graft presents itself as an excellent reconstructive option, especially considering its low morbidity, availability and ability to retrieve an adequate amount of cartilage in the vast majority of patients. These modifications of the conchal cartilage are previously unreported, and provide the needed height and elasticity in saddle nose reconstruction without the need for additional grafting. It is important to stress that when positioned properly, a beneficial effect in peak nasal inspiratory flow may be observed, adding to its usefulness in repairing both function and aesthetics.
