Sandwich technique in nasal dorsal augmentation.

Tutoplast fascia lata (TFL) has been used as an onlay graft for nasal dorsal augmentation in open approach rhinoplasty; however, insertion of layers of moist TFL in the closed approach is technically challenging. We have presented a "sandwich" technique which facilitates graft insertion in a closed approach rhinoplasty. The available autologous graft (cartilage or perpendicular plate of ethmoid) is sandwiched and secured between layers of TFL (sandwich technique) prior to insertion of the graft for nasal dorsal augmentation in a closed rhinoplasty approach. All our cases of nasal dorsal augmentation were reviewed in a 2 year period. Eight cases of nasal dorsal augmentation in secondary rhinoplasty through a closed approach were reviewed. The ease of insertion and the subsequent manipulation of the graft were noted in all the cases. Good aesthetic results have been noticed in all the cases after an average of 14 months follow-up. The sandwich technique ensures ease of the graft insertion and the subsequent manipulation in a closed approach secondary rhinoplasty for dorsal augmentation.
