Inferior Turbinate Bone Graft for Dorsal Augmentation in Rhinoplasty

The most serious form of nasal dorsum pathologies is saddle nose deformity. Vary of nasal dorsal augmentation grafts were reported in the literature but inferior bone graft (ITBG) alone has not attracted attention. The ITBG has advantages such as easy and fast harvesting, easy to shape due to cancellous bone tissue. The graft technique is similar to the inferior turbinoplasty with the medial mucosal flap technique and can be performed without bioabsorbable hemostatic material (e.g. Turkish Delight), suture fixation, or without tissue adhesives. Major complications of the ITBG technique are injury of the posterior lateral nasal branch of the sphenopalatine artery and subdermal mucous cyst that developing on nasal dorsum. Since easy application, fast harvesting, and similar permanence to cartilage grafts as augmentation material, ITBG can also been used successfully in minor dorsal deficits in addition to saddle nose deformities.
