Autogenous control augmentation system - A refinement in diced cartilage glue graft for augmentation of dorsum of nose.

[BACKGROUND] In the context of different grafts being used for dorsal augmentation, diced cartilage with glue has gained worldwide acceptance.

[AIMS] To develop a system of tools to objectively evaluate the desired dimensions of the required graft for dorsal augmentation and to prepare a corresponding customized-glued-diced cartilage construct.

[MATERIALS AND METHODS] A modification of the diced cartilage glue technique called Autogenous control augmentation system (ACAS) was used in ten patients.

[RESULTS] Of the ten patients, in which this technique was used, eight underwent primary rhinoplasties and two underwent secondary rhinoplasties between July 2017 and December 2017 with a follow-up ranging from 3 to 8 months. In all the cases, the dorsum is straight, and height is maintained.

[CONCLUSION] The technique has all the advantages of the diced cartilage glue. The shape resembles alloplastic implant with height and width varying from radix to tip. There is tapering of the cephalic and caudal ends for more natural results. The brow tip aesthetic lines are better defined. The limitation of this study is short follow up.
