Abstract
A prospective study utilizing image analysis to assess nostril openings in post-operative patients with cleft lip and cleft lip nose deformities. This preliminary study seeks to employ two-dimensional (2D) images to fabricate a custom-made nostril retainer. This study was performed at Faculty of Medicine, Siriraj Hospital, Mahidol University, Thailand. This study included 30 healthy volunteers and 15 patients with cleft lip and cleft lip nose deformities. The nostril opening width and height for all participants were measured, and photographs were taken. An image analysis application was used to fabricate a three-dimensional (3D) custom-made nostril retainer. The mean differences between the direct measurements of the nostril aperture and the measurements obtained through the program did not exceed 2 mm in terms of nostril height, width, or columella. Two-dimensional photographs can be used to create a custom-made, three-dimensional nostril retainer. This retainer allows post-operative patients to maintain their nares without needing to visit the hospital, thereby reducing the cost of care.
