Production of custom-made bungs using computed tomography and rapid prototyping: a novel method to correct nasoseptal defects

摘要

Nonsurgical closure of septal perforations with septal buttons or obturators is reported as an effective alternative to operation,1'2 but inaccuracies at each stage of a traditional construction process can lead to ill-fitting prostheses and persistent distressing symptoms for the patient. We describe a new technique for accurate construction of a custom-made nasal bung with the collaboration of rapid prototyping bureaus, prosthetists, and clinicians.
