Aim
To identify the optimal depth of penetration required to access the superior joint space (SJS) for arthroscopic procedures of the temporomandibular joint (TMJ) among the study population.
Materials and Methods
The study included all patients with internal derangement (ID) of the TMJ, managed by TMJ arthroscopy in our institution. The study was conducted with data retrieved from the hospital records over five years (January 2018–April 2022). Demographic factors and depth of penetration (mms) were the variables included in our study. For all the statistical interpretations, p < 0.05 was considered statistically significant.
Results
The study included 66 patients (males, n = 25; females, n = 41) who underwent arthroscopic procedures of the TMJ (right = 29, left = 37). The mean duration between the development of symptoms and the point of intervention (TMJ arthroscopy) in our study was 3.94 months. The mean depth of penetration of the arthroscope as measured from the skin to the point of entry into the SJS was 20.60 ± 1.85 mms in males and 19.56 ± 1.38 mms in females (p value < 0.05). Variables such as age, duration of symptoms, side involved and stage of ID did not have any influence on the optimal depth of penetration required to access the joint space among our study population.
Conclusion
The optimal depth of penetration (mean) required to access the SJS was less than 25 mms in our study population.
