“…Most authors assessed patient satisfaction by means of the Global Aesthetic Improvement Scale (GAIS) or the Quality of Life Assessment (QoLA) score [10,11], and only very few attempted to evaluate treatment results in a more objective manner by using ultrasonographic measurements of facial tissues [9,23]. Due to its excellent soft tissue discrimination and the possibility to obtain quantitative data, magnetic resonance imaging (MRI) is increasingly used for the evaluation of injectable dermal fillers [25]. The purpose of the current study was to assess the morphology of facial tissues after subdermal HA injection as well as to describe temporal changes regarding in vivo distribution, effects on local vascularization and volumetric changes during the first 12 months by means of serial MRI examinations.…”

Objective: This prospective observational study evaluated magnetic resonance imaging (MRI) findings of hyaluronic acid (HA) injections used for the correction of HIV-associated facial lipoatrophy. Methods: Ten consecutive males underwent subdermal HA injection (mean 1.3 ± 0.6 ml per side) and MRI examinations prior to and then 1, 6 and 12 months after injection. Two radiologists blinded to the clinical data assessed morphologic and quantitative changes. Results: MRI revealed HA deposition in the subdermal and deep fat compartments. A significant HA volume increase was observed 1 month after injection (mean increase 331%, p < 0.0001) as compared to the injected amount. No volume reduction occurred at 12 months (p = 0.9961). The measured bound water content did not change (p > 0.9991), whereas skin thickness and tissue vascularization increased during the first 6 months (p = 0.01). Conclusion: Our data show that the cosmetic results of HA injections are caused by water binding in the deep facial fat and by a transient increase in vascularization and skin thickness.

SUMMARY:A wide variety of implants and grafts have been used for cosmetic facial surgery, including forehead, nose, cheek, lip, and chin augmentation. Some of the implant materials include silicone, expanded polytetrafluoroethylene (Gore-Tex), hydroxylapatite, and porous polyethylene (Medpor). Grafts include bone and cartilage, which can be prepared as "Turkish Delight" for rhinoplasty. Imaged facial implants and grafts can be encountered incidentally or purposely to evaluate complications. Many of these materials have distinct radiologic imaging features and should not be misinterpreted as pathology. Conversely, implant complications should be appropriately recognized by using a focused imaging approach. The purpose of this article was to review the different types of cosmetic facial implants and grafts with an emphasis on their expected and complicated radiologic imaging appearances.

“…27 Calcium hydroxylapatite displays high attenuation on CT (Fig 8). 28 Metallic Kirschner wires can be used for restoration of an impacted nasal pyramid, fixation of intraoperative nasal septum fractures, and stabilization of costal cartilage grafts. [29][30][31] K-wires can be implanted in the nasal dorsum, columella, or both because in an L-strut configuration, a wire is positioned along the dorsum (Fig 9).…”

SUMMARY:Cosmetic rhinoplasty encompasses a diverse group of procedures, including alteration of the radix, nasal dorsum, nasal tip, and nasal base; premaxillary augmentation; septoplasty; and combinations thereof. Similarly, many different types of grafts and alloplastic materials can be used in cosmetic rhinoplasty, such as cartilage, bone, silicone, porous polyethylene, expanded polytetrafluoroethylene, and calcium hydroxylapatite. Complications of rhinoplasty that can be observed on imaging include retained metallic surgical instrument fragments, infection, implant extrusion, nerve impingement by implants, nasal valve collapse, and implant deformity. Knowledge of the basic surgical procedures and potential complications of cosmetic rhinoplasty is important for adequately interpreting postoperative radiologic imaging studies.
