Facial fat grafts if hyaluronic filler is contraindicated? (Photos)

I have atrophic dents in my upper cheek/tear trough after Kenalog 5 injections to treat a foreign-body granuloma (histologic diagnosis) caused by Juvederm Voluma. The Kenalog was injected 12 mnths ago. Some of the surgeons and derms I have seen warmly recommended fat grafts and stated that complications are rare & largely technique-dependent, while others vehemently discouraged me by listing horrible complications. What is your experience? Or should I try a less cross-linked HA filler instead?
