Background Temporomandibular joint (TMJ) internal derangement is multifactorial, and many studies show that the patient’s age influences internal derangement and its response to treatment. Objectives This study proposed to investigate the relation of age with the stage of internal derangement and its improvement after nano-fat injection. Materials and Methods Thirty-eight temporomandibular joints for twenty patients were included. All involved patients were previously diagnosed with internal derangement (ID) depending on Wilkes classification clinically and radiographically, ID stages II, III, IV, and V were included. Nano-fat was used as an injection in superior joint space. The evaluation was done depending on pain assessment using a visual analogue scale and measuring maximum mouth opening in the pre-injection phase, one month, three months, and six months after injection. Paired T-Test were used to compare the continuous variables and Pearson Correlation to show age and stage relation. P–value less than 0.05 was considered significant. Results Patients’ mean age was 29.75 years. The most frequent stage of TMJs was stage III (n=23 joints), followed by stage II (n=9 joints), stage IV (n=5 joints), and stage V in one joint. The (r = .324*) between patient age and stage of ID. All age groups show significant improvement after injection, unlike stage IV, and V groups. They showed insignificant improvement in mouth opening in all follow-up appointments. Conclusion Internal derangement can affect persons of any age. The severity of ID increases with age. According to the study results, the nano-fat injection is safe, reduces the TMJ pain, and is free from noticeable complications MMO in different age groups and stages II, III, IV, and V of ID in varying degrees.
