Abstract：Objective To investigate the efficacy of anterior disc displacement without reduction(ADDWoR)in elderly patients with superior temporomandibular joint lavage combined with occlusive plate.Methods Eighty patients with ADDWoR admitted to Bethune International Peace Hospital from January 2023 to December 2023 were selected,all of whom were treated with temporomandibular joint superior cavity lavage combined with occlusal plate.The maximum mouth opening,facial pain,articular disc morphology and exudation changes,mandibular function and quality of life were compared before and after treatment.Analyze the curative effect of patients after treatment.Results The maximal mouth opening(MMO)of the patients was higher at 3 and 6 months after treatment than before treatment,and the MMO was higher at 6 months after treatment than at 3 months after treatment(P＜0.05).The scores of gaping and masticating pain at 3 and 6 months after treatment were lower than those before treatment,and the scores of gaping and masticating pain at 6 months after treatment were lower than those at 3 months after treatment(P＜0.05).Six months after treatment,the proportion of deformed articular disc was higher than that before treatment(98.75％vs 91.25％,P＜0.05),and the detection rate of joint exudation was lower than that before treatment(2.50％vs 37.50％,P＜0.01).Six months after treatment,the scores of jaw functional limitation scale and oral health implant profile-14 were lower than those before treatment(P＜0.05,P＜0.01).Of the 80 patients,8 were cured,52 were markedly effective,17 were effective and 3 were ineffective.The total effective rate was 96.25％.Conclusion Temporomandibular joint upper cavity lavage combined with occlusal plate can effectively improve mouth opening,facial pain,joint disc shape and fluid seepage in elderly patients with ADDWoR,and improve mandibular function and quality of life.
