Objective: To compare the average mouth opening reduction caused by autologous blood injection in the superior joint space with and without pericapsular tissue in the management of chronic recurrent TMJ dislocation.
Methodology: The study was conducted in Oral and Maxillofacial Surgery Department / Dental Section, Aziz Fatima Hospital (AFMDC) Faisalabad, from April 2021 to April 2022. In total 152 patients were randomly split into two equal groups. The auriculotemporal nerve was numbed with local anesthetic. An 18-gauge needle was placed into SJS at this point utilizing a single needle method. After instructing the patients to open their mouths as wide as possible, the width in between incisal borders of the lower and the upper incisors was determined. In addition, 3cc of blood were taken from the antecubital fossa of the patients and injected in a syringe. Group B got autologous blood injections to the SJS and the pericapsular tissues, while Group A received ABI into the superior joint space only.
Results: The mean age of group A was 32.24 ± 8.94 years and group B was 31.38 ± 8.34 years. The gender distribution was also similar in both groups (P-value > 0.05) with female dominance having (55.26%) females in group A and (59.21%) in group B. Post injection comparison of mouth opening showed that group B patients had a significantly (P-value < 0.05) less mean value (44.53 ± 2.46 mm) of mouth opening as compared to (46.04 ± 2.27 mm) among patients in group A. The decrease in mouth opening showed that group B patients had significantly (P-value < 0.05) higher decrease in mouth opening with a mean value of (5.35 ± 1.46 mm) as compared to (3.40 ± 1.01 mm) in group A.
Conclusions: The use of autologous blood injection as a treatment for TMJ dislocation in individuals with persistent recurrent dislocation was discovered to be a convenient, safe, and economical method. The ABI in TMJ with PT demonstrated a considerably greater rate of success in terms of the reduction in jaw opening.
