Abstract
INTRODUCTION: Saddle nose deformities are typically reconstructed with cartilage grafts; however, conchal cartilage grafts are and associated with a risk of damage to the posterior auricular ligament and insufficient amounts, and costal cartilage grafts require invasive surgery under general anesthesia. We proposed a double-layer dermofat graft as an alternative to these methods. PATIENT CONCERNS: Two patients with type IV saddle nose deformity underwent reconstruction with nasal augmentation with a double-layer dermofat graft harvested from the gluteal sulcus. DIAGNOSIS: After operation, photogrammetric analysis demonstrated an improvement in the dorsal depression area, which corresponded to the angle between the sellion, most depressed point, and pronasale. Rhinoplasty Outcome Evaluation questionnaire was assessed. INTERVENTIONS: The graft was divided into 2 sections; the first section was implanted transversely into the depressed nasal framework, and the second section was inserted vertically from the nasion to the supratip break for augmentation. OUTCOMES: Both patients reported high satisfaction with the Rhinoplasty Outcome Evaluation questionnaire. The mean preoperative angle between the sellion, most depressed point, and pronasale was 157.8°, and the mean postoperative angle at 6 months was 176.9°. CONCLUSION: The simple method double-layer dermofat graft technique demonstrated excellent outcomes in saddle nose deformity correction, did not require cartilage, and was easily performed under local anesthesia.
