Computational technology for nasal cartilage-related clinical research and application.

ABSTRACT: Surgeons need to understand the effects of the nasal cartilage on facial morphology, the function of both soft tissues and hard tissues and nasal function when performing nasal surgery. In nasal cartilage-related surgery, the main goals for clinical research should include clarification of surgical goals, rationalization of surgical methods, precision and personalization of surgical design and preparation and improved convenience of doctor-patient communication. Computational technology has become an effective way to achieve these goals. Advances in three-dimensional (3D) imaging technology will promote nasal cartilage-related applications, including research on computational modelling technology, computational simulation technology, virtual surgery planning and 3D printing technology. These technologies are destined to revolutionize nasal surgery further. In this review, we summarize the advantages, latest findings and application progress of various computational technologies used in clinical nasal cartilage-related work and research. The application prospects of each technique are also discussed.

Project description:ImportanceStudies have shown the controllability and porosity of polycaprolactone as well as the use of 3-dimensional (3-D) printing for nasal reconstruction in animal models. The utility of polycaprolactone with 3-D technology in nasal cartilaginous framework reconstruction in humans remains unknown.ObjectiveTo investigate the safety and efficacy of 3-D printed, bioresorbable polycaprolactone nasal implants.Design, setting, and participantsThis multicenter clinical trial comprised 20 patients with caudal septal deviations who underwent septoplasty, which used a 3-D printed polycaprolactone mesh, at 2 centers in South Korea. Patients were included if they were aged 18 to 74 years and had nasal septal deviations, Nasal Obstruction Symptom Evaluation scores greater than 20, and persistent nasal obstructions. Twenty-two patients met the inclusion criteria, but 2 patients were excluded before the operation. The study was conducted from July 1, 2016, to June 30, 2017.Main outcomes and measuresThe change in total Nasal Obstruction Symptom Evaluation score between the preoperative examination and the week 12 postoperative examination was the primary outcome. Changes in bilateral nasal cavity minimum cross-sectional area and volume on acoustic rhinometry at weeks 4 and 12 after the operation as well as changes in the nasal cavity cross-sectional area at the osteomeatal unit and nasal septum angle in the paranasal sinus on computed tomography after week 12 were among the secondary outcomes.ResultsOf the 20 patients included in the study, 4 (20%) were female, 16 (80%) were male, with a mean (SD) age of 34.95 (11.96) years. The preoperative and week 12 postoperative results revealed significant changes in the minimal cross-sectional areas on acoustic rhinometry (0.41 [SD, 0.39] vs -0.11 [SD, 0.18]; difference, 0.42; 95% CI, 0.23-0.61), nasal septum angles on computed tomography (11.22 [SD, 6.57] vs 2.89 [SD, 3.12]; difference, 8.33; 95% CI, 5.08-11.58), and Nasal Obstruction Symptom Evaluation scores (73.50 [SD, 19.88] vs 3.75 [SD, 6.26]; difference, 69.75; 95% CI, 59.22-80.28). The surgeons' convenience level with the procedure was favorable (visual analog scale score [SD], 90.90 [9.45]), and so were the patients' symptom improvements and satisfaction after 12 weeks (visual analog scale score [SD], 88.30 [9.87]).Conclusions and relevanceThe 3-D printed, homogeneous, composite, microporous polycaprolactone nasal implant demonstrated proper mechanical support and thinness with excellent biocompatibility and surgical manipulability. Polycaprolactone may be a clinically biocompatible material for use in various craniofacial reconstructions in the future.
