After I first joined at 1996 AAO-HNSF Annual Meeting in Washington, DC as residency, I became interested in high resolution nasal endoscopy and I planned study design for allergic rhinitis patients. Research diagram of DANYOUNG classification consist of the study design, with the three periods at 20 years strategic plan. Using digital HD 3chip endoscopy, digital HD Flexible videoendoscopy and 3chip endoscopy, DANYOUNG classification 2015 update is achieved by better objective visual data files.
From Jun 2001 to Apr 2015, nasoendoscopic video data files were collected from allergic rhinitis patients.
Nasoendoscopic video system is consist of stryker digital HD 3chip video camera system 1488 model, kay pentax digital HD Flexible videoendoscopy VNL-1190STK model and stryker 3chip video camera system 888, 988, 1088 model. Video data storage system is consist of stryker SDC-pro, SDC-HD, SDC3 recording system and NAS-LG system.
DANYOUNG classification hypothesis based on surface change of allergic rhinitis patient’s inferior turbinate mucosa.
This classification consist of 3 stages. Stage 1 is hypertrophy state. Stage 2 is dimple state. Stage 3 is wrinkle state. A clear definition of stage is more characterized under digital HD endoscopic evaluation. Especially, irreversible change of nasal mucosa such as dimple and wrinkle shape is confirmed again.
DANYOUNG classification has very simple, objective advantage and useful on early diagnosis of allergic rhinitis. When OMU-CT is using together for allergic rhinitis patient, this staging is clear more than.
DANYOUNG classification 2015 update can related on ARIA 2010 update, can be one in the future.
