title: Key and Keyhole Model for Dorsal Onlay Cartilage Grafts in Correcting Nasal Deformities.
abstract: BACKGROUND
  The shaping of the cartilage and keeping it in place is very significant for patients who need nasal reconstruction with costal grafts at traumatic or secondary rhinoplasties. In this study, a template is prepared during the surgery that shows the dorsal defect in a 3-dimensional manner and acts as a guide while shaping the cartilage.
  
  
  METHODS
  Seventeen patients who required secondary rhinoplasties because of trauma or previous operations were included in this study. The patients were operated on between the years 2009 and 2013. The mean age of the patients was 24 years (19-38 years). According to the surgical technique, bone wax was placed in a sheath prepared from the finger of a sterile nylon surgical glove before the dorsal reconstruction. It was placed to the nasal dorsum and shaped over the skin with digital maneuvers. Afterward, the bone wax was stripped off the nylon glove, and it was used as a template to shape the cartilage graft.
  
  
  RESULTS
  No need for revision rhinoplasties was seen in any of the patients during the mean follow-up period of 19 months. The patients stated that they were satisfied by both the functional and the aesthetic results.
  
  
  CONCLUSIONS
  The bone wax template and the defect fit in a key and keyhole fashion. It is supported by multiple points on the nasal bone and the septum. Thus, it does not slide and its warping is avoided. We think that it gives satisfactory results and it shortens the learning process.
