ABSTRACT
The role of buccal fat pad (BFP) as interpositional material in the temporomandibular joint ankylosis (TMJA) have been well documented. The purpose of the present systematic review is to reinforce the role of buccal fat pad as interpositional material in preventing re-ankylosis. A systematic search was conducted in PubMed, Google Scholar, Semantic scholar and Cochrane library database from 1980 to 2022 following the PRISMA guidelines. The studies using BFP as interpositional material in TMJA with more than 10 patients with atleast a follow-up of 6-months were included. All the human studies {prospective, retrospective, case reports/series (with more than 10 subjects), randomized or non-randomized trial) reporting the outcome of BFP as interpositional material were included. The present systematic review included 11 studies (prospective=7, Retrospective=3 and ambispective=1) using BFP as interpositional material. The total number of patients were 205. The number of unilateral TMJA and bilateral TMJA were 153 and 52 respectively, making a number of joint to 257. The distribution of gender was almost equal (few studies did not report the gender distribution). The minimum follow-up was 6-months and extended up to 5.3 years. Out of 205 patients, no re-ankylosis was reported in patients. The authors concluded that the BFP is nearly ideal and a preferred interpositional material to prevent re-ankylosis in temporomandibular joint ankylosis. Its vicinity to TMJ, ease of harvesting through the same surgical site and avoiding other scar makes it a preferred interpositional material in TMJA cases.
