Orbital Fat Injection: Technique and 5-Year Follow-Up
Abstract
Orbital volume loss, early or late, is common after placement of an orbital implant or dermis fat graft, and there is currently no satisfactory long-lasting solution. Hyaluronic fillers are relatively easy to administer but are prone to migration and are temporary. Cannula-based orbital fat grafting has not gained the status of standard of care because of perceived low likelihood of success in the near term. This paper describes a technique for fat volume augmentation, its rationale, long-term follow-up, and a description of a complication unique to fat grafting in the orbit. Ten consecutive subjects with acquired anophthalmic enophthalmos were enrolled in two IRB (institutional review board)-approved protocols (10.27 and 12.01) undergoing a single session of autologous fat grafting to the orbit using a closed blunt cannula technique. Preoperative photography and non-contrast MRIs (magnetic resonance imaging) were obtained prior, immediately after, and at 1 year after injection. Yearly postoperative photography was performed on subjects with successful results. Three of five subjects in IRB 10.27 clearly showed a clinically apparent increase in orbital volume at 1 year. One subject who failed to show improvement also sustained ...Continue Reading

Cell Migration
Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.
