Health condition(s) or Problem(s) studied | cleft lip and palate |
Date of first enrollment | 24/11/2022 |
Target sample size | 10 |

Study type | Interventional |
Intervention(s) | Attaching the nasal device to the nostrils |
Outcome(s)

---|---|
Secondary Outcome | Validity evaluation The following items of nasal morphology will be measured using a non-contact scanner. Length of the base of the nasal wings, height of the nostril margin, width of the nostril margin, angle of the nasal column, height of the nostrils, and width of the nostrils on the affected and healthy sides. Differences between the left and right sides of the nose and changes before, 4 weeks, at the end of, and 4 weeks after the postoperative observation period. Efficacy is judged to be present if any of the following are met. a The height of the affected nostril is greater than 80% of the height of the healthy nostril after the device is installed. b The width of the nostril margin on the healthy side after the device is placed is greater than 80% of the width of the nostril margin on the affected side. c The base length of the nasal wing after the device is more than 90% of the base length of the nasal wing before the device. The rate of home use should be checked in the patient diary. |
