Abstract:
Objective:To discuss the efficacy of temporomandibular joint disc anchoring(TMJDA)in the treatment of anterior disc displacement without reduction(ADDWoR)from clinical and imaging perspectives,in order to improve the clinicians'understanding of this surgical approach.Methods:Twenty-one ADDWoR patients who underwent TMJDA were retrospectively collected,involving a total of 25 temporomandibular joints(TMJs).The maximum mouth opening,visual analogue scale(VAS)score for pain,and Helkimo index were measured preoperatively,1 month postoperatively,and 6 months postoperatively in all the patients.Postoperative complications and satisfaction questionnaires were designed for the patients to self-evaluate the efficacy,and their magnetic resonance imaging(MRI)findings were assessed.Results:Compared with preoperative period,the maximum mouth opening at 1 month and 6 months postoperatively was significantly increased(P<0.05);compared with 1 month postoperatively,the maximum mouth opening at 6 months postoperatively was significantly increased(P<0.05).Compared with preoperative period,the VAS scores at 1 month and 6 months postoperatively were significantly decreased(P<0.05);compared with 1 month postoperatively,the VAS score at 6 months postoperatively was significantly decreased(P<0.05).Compared with preoperative period,the percentages of the patients with Di 0 and DiⅠ scores were significantly increased(P<0.05),while those with DiⅡand DiⅢ scores were significantly decreased(P<0.05),indicating significant improvement in TMJ function after surgery.Among the 21 ADDWoR patients,14(66.67%)were satisfied and 7(33.33%)were basically satisfied.Compared with preoperative period,the disc length was significantly increased postoperatively(P<0.01),while no significant difference was observed in condylar height(P>0.05);all displaced discs were repositioned postoperatively;among the 25 joints,23(92.00%)were evaluated as"excellent"and 2(8.00%)were evaluated as"good".No patients experienced postoperative facial nerve injury,local alopecia,surgical area depression,salivary fistula,or Frey syndrome;3 patients(3 joints)developed numbness in the preauricular area within 24 hours postoperatively,which resolved by the 6-month follow-up.Conclusion:TMJDA for the treatment of ADDWoR can stably reposition the disc,significantly improve mouth opening and pain levels,with a low incidence of postoperative complications.
