Application of a Novel 3D-Printed Nasal Plug as a Conservative Treatment for Empty Nose Syndrome.

Objective: Empty nose syndrome (ENS) is commonly treated by surgery, albeit with limited success. Herein, we introduce our experience of applying a newly developed "3D-printed nasal plug" as an alternative conservative treatment modality.

Methods: This retrospective study included 20 patients (14 males, 6 females; mean age 46.

Efficacy and feasibility of a forehead flap surgical guide for nasal reconstruction.

For successful nasal reconstruction using a forehead flap, three-dimensional (3D) nasal defects need to be translated into a two-dimensional (2D) forehead surface. For this study, a patient-specific 3D-printed forehead flap guide that could precisely translate a virtually simulated nasal shape into a 2D flap template was developed. The study aimed to evaluate the feasibility and efficacy of a 3D-printed forehead flap guide for nasal reconstructions.

Dorsal Augmentation Using a Glued Diced Cartilage Graft Fashioned with a Newly Developed Mold in Asian Rhinoplasty.

Background: In dorsal augmentation, costal cartilage can be used in a number of different ways: monobloc, fascia wrapped, or glued diced cartilage grafting (GDCG). The authors developed a mold to make the use of GDCG more convenient. This report describes their experience with GDCG using a novel mold for dorsal augmentation.

The mechanical characteristics and performance evaluation of a newly developed silicone airway stent (GINA stent).

Central airway obstruction (CAO) can be attributed to several benign or malignant conditions. Although surgery is the preferred therapeutic option for the management of CAO, bronchoscopic treatment can be performed in scenarios where the surgical procedure is not possible. Recent years have witnessed several improvements in the field of bronchoscopic treatment, especially with regard to airway stents.

Clinical Application of a Patient-Specific, Three-Dimensional Printing Guide Based on Computer Simulation for Rhinoplasty.

Background: A practical application of three-dimensional printing technology has been considered a difficult area in rhinoplasty. However, the patient-specific three-dimensionally printed rhinoplasty guide based on the simulation program the authors developed could be a solution for minimizing the gap between simulation and actual surgical results. The aims of this study were to determine how a three-dimensional rhinoplasty guide based on three-dimensional simulation would link the patient to the surgeon to investigate its effectiveness.

Comprehensive Three-Dimensional Technology Strategies for Autologous Free Fat Graft in Parry-Romberg Syndrome.

Autologous free fat graft is a widely accepted method of facial contour restoration in Parry-Romberg syndrome (PRS); however, complex and unpredictable facial anatomy can render this surgery extremely challenging. The integration of 3-dimensional (3D) technology strategies as a method to enhance surgical aesthetic outcomes has been demonstrated.A retrospective chart review was performed for PRS with autologous, free fat graft between 2016 and 2017.
