“…The majority ( n = 11) of these studies reported on the use of antibiotics and biologic medications, with only two mentioning retinoids [ 47 , 62 ]. Of these, one study discussed post-surgical use of biologics [ 18 ], four studies detailed use of biologics and antibiotics in the weeks or months preceding surgery [ 37 , 39 , 56 , 63 ], three detailed antibiotic and/or biologic use both pre- and post-surgical intervention [ 41 , 46 , 64 ], one detailed intraoperative use of a gentamicin sponge [ 11 ], and two studies did not specify exact timing [ 47 , 54 ]. Prens et al [ 46 ] reported significantly longer healing times with the use of adalimumab (five patients) and infliximab (one patient) started several months before surgery, held for 1–2 weeks perioperatively, and then re-instated postoperatively within 1–2 weeks.…”
