A Decade Retrospective Study Of Light/Laser Devices In Treating Nasal Rosacea

Background:Large-scale retrospective studies of light/laser in treating nasal rosacea were lacking.Objective:The study was aimed to perform a decade retrospection of the patients with nasal rosacea who were treated with light/laser devices.Methods:Methods:A study between 2008 and 2017 was performed retrospectively.Categorization of rosacea type（erythema/telangiectasia,ET;papules/pustules,PP;rhinophyma,RP）was made according to the photographs.Device settings,treatment regimens and treatment sessions of light/laser facilities were summarized.Efficacy was evaluated using a grading scale.Results:In all,807 patients received light/laser treatments.The subtypes of nasal rosacea were ET（n=196）,PP（n=95）,RP（n=42）,ET+PP（n=334）,ET+RP（n=15）,PP+RP（n=88）,and ET+PP+RP（n=37）.The lesions of ET or PP were mainly treated with non-invasive devices（Intense pulsed light,IPL;Dye pulse light,DPL;Dual wavelength laser system,DW）and those of RP were treated with the Fractional carbon dioxide（FCO₂）laser.For the mixed subtypes,the general disposal orders of lesions were ET,PP and later RP.And the fundamental orders of devices application were IPL,DPL,DW and FCO₂ laser.For all types of rosacea except for RP（2-4 sessions）,most of the patients received 4-6sessions of treatments.Of all subtypes of ET,PP,RP,ET+PP,ET+RP,PP+RP,ET+PP+RP,the patients who achieved more than 50%improvement accounted for74.5%,58.3%,83.3%,69.2%,73.3%,61.4%,51.4%,respectively.Conclusion:The multiple,sequential light/laser devices can be safely used in nasal rosacea with various degrees efficacies based on different types.
