Temporomandibular disorders (TMD) are highly prevalent and frequently associated with chronic pain and functional impairment, forming part of the diagnostic spectrum in cranio-maxillofacial surgery. Scalable, self-managed interventions - including home-exercise programs, psychoeducational strategies, and digitally supported approaches - are increasingly used, yet their pooled effectiveness has not been systematically quantified. A systematic search of PubMed, Scopus, and Cochrane CENTRAL identified randomized controlled trials evaluating predominantly self-managed or remotely delivered interventions for TMD. Eligible studies were qualitatively synthesized, and trials providing sufficient numerical data were meta-analyzed. Standardized mean differences (Hedges' g) were calculated using random-effects models; heterogeneity, prediction intervals, robustness, and publication bias were assessed. Self-managed interventions produced a statistically significant and clinically meaningful reduction in pain (SMD = -0.78; 95% CI -1.33 to -0.24; p = 0.005; I2 = 84%), with robust findings in sensitivity analyses. For maximal mouth opening, the pooled estimate showed a nonsignificant trend toward improved mandibular mobility (SMD = 0.63; 95% CI -0.11 to 1.37; I2 = 91%). These findings support structured self-management strategies as effective components of contemporary TMD care pathways, with direct relevance for evidence-based indication setting and patient counseling in cranio-maxillofacial practice.
