Comparison between Wrapping Dice Cartilage with Temporal Fascia and Wrapping in Alloderm for Dorsal Nasal Augmentation

BACKGROUND: Dorsal augmentation of the nose for aesthetic and reconstructive purposes is an important issue in rhinoplasty surgery. This study aimed to compare the two methods of dice cartilage wrapping for dorsal augmentation of the nose including temporalis fascia and alloderm. METHODS: In a clinical trial study, 50 patients who needed to augment the nasal dorsum, were enrolled and randomly allocated to two equal groups. In the first group, diced cartilage graft of the patient was wrapped in temporalis fascia and in the second group, a thin sheet of alloderm was used for this purpose. After one year follow up, satisfaction of patients and the expert panel were compared in two groups. Also mean increase in dorsal height was measured and compared in two groups. RESULTS: The mean increase of dorsal nasal height one year after surgery in the alloderm and temporalis fascia was 3.13±0.49 and 3.42±0.33, respectively and in the fascia group was significantly higher (p=0.02). The mean of patients’ satisfaction in the two groups of alloderm and temporal fascia groups was 7.48±0.92 and 8.04±0.89, respectively (p=0.03). The mean satisfaction of expert panel in the two methods was 7.56±0.81 and 7.7±0.63, respectively (p=0.5). CONCLUSION: The use of temporal fascia for covering the diced cartilage in augmentation of nasal dorsum had better results than the alloderm. Patients satisfaction and mean dorsal height was higher in temporal fascia group.
