AB  - BACKGROUND: Nasal septum perforations (NSP) have many uncomfortable symptoms for 
      the patient and a highly negative impact on quality of life. NSPs are closed 
      using patient-specific implants or surgery. Implants are created either under 
      anesthesia using silicone impressions or using 3D models from CT data. 
      Disadvantages for patient safety are the increased risk of morbidity or radiation 
      exposure. MATERIALS AND METHODS: In the context of otorhinolaryngologic surgery, 
      we present a gentle approach to treating NSP with a new image-based, contactless, 
      and radiation-free measurement method using a 3D endoscope. The method relies on 
      image information only and makes use of real-time capable computer vision 
      algorithms to compute 3D information. This endoscopic method can be repeated as 
      often as desired in the clinical course and has already proven its accuracy and 
      robustness for robotic-assisted surgery (RAS) and surgical microscopy. We expand 
      our method for nasal surgery, as there are additional spatial and 
      stereoperspective challenges. RESULTS: After measuring 3 relevant parameters (NSP 
      extension: axial, coronal, and NSP circumference) of 6 patients and comparing the 
      results of 2 stereoendoscopes with CT data, it was shown that the image-based 
      measurements can achieve comparable accuracies to CT data. One patient could be 
      only partially evaluated because the NSP was larger than the endoscopic field of 
      view. CONCLUSION: Based on the very good measurements, we outline a therapeutic 
      procedure which should enable the production of patient-specific NSP implants 
      based on endoscopic data only.
