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 46.5 ± 13.5 years) with ENS who underwent the application of the 3D‐printed nasal plug at Asan Medical Center between June 2022 and May 2023. Symptom improvement was assessed by Empty Nose Syndrome 6‐Item Questionnaire (ENS6Q) before and after applying the nasal plug. Clinical results, such as duration and frequency of plug use, discomfort, and level of satisfaction, were investigated.
Results
The mean follow‐up duration was 40.3 ± 24.2 weeks. The average duration of nasal plug usage was 10.8 h per day and 5.3 days a week. The ENS6Q scores improved from 19.6 ± 4.6 to 6.8 ± 5.1 (mean reduction 12.8 ± 5.9) after 30 minutes of wearing. Symptom “nose feelings too open” was improved most by a score of 3.0 ± 1.5 (p < 0.001). Thirteen patients (65.0%) reported that the effectiveness of the plug, initially confirmed at the first wearing, was well maintained during the entire follow‐up. Four patients (20.0%) wore the nasal plug uninterruptedly throughout the week, whereas nine patients (45.0%) wore it intermittently as needed. Frequently reported complaints with plug usage were ‘displacement of the plug’ and ‘cosmetic concerns’ about the visible hook portion.
Conclusion
A 3D‐designed nasal plug can be a useful conservative treatment option for ENS patients.
