Abstract

The aim of the study is to evaluate the effectiveness of TMJ arthrocentesis procedure in patients with internal derangement of TMJ. This retrospective study analysed the data of 86000 patients,record of 22 patients who have underwent arthrocentesis procedure were obtained,7 patients were filtered out as the study population based on the strict exclusion and inclusion criteria. Parameters such as Pre Op & Post OP VAS(Visual Analogue Scale) score,technique used were included.Data was recorded in Microsoft Excel 2007 software and then exported to IBM SPSS 20 Statistics Software.

The Post Op VAS score ranged from 0-2 and the mean of the Post OP VAS score mean=0.29 +.756. Two types of techniques were used;Single injection technique n=4 and Double injection technique n=3. Statistical analysis for correlation was done using Pearson’s correlation method and it was found that the positive correlation was seen between Pre op VAS Score and Post op VAS Score (P
