Patient safety considerations regarding dermal filler injections

Foreign body reactions related to orofacial esthetic fillers: A systematic review

The aim of this study was to systematically review the clinicopathological data regarding foreign body reactions (FBR) related to esthetic procedures in the orofacial region. Electronic searches were performed in six databases and in gray literature using PEO acronym for the review question. Case series and case reports describing FBR related to esthetic procedures in the orofacial region were included. The JBI Critical Appraisal Checklist-University of Adelaide tool was used for measuring the risk of bias. Eighty-six studies reporting 139 cases of FBR were identified. The mean age at diagnosis was 54.12 years (14-85 years), with most of the cases reported in America, North America (n = 42/30.70%) and Latin America (n = 33/23.60%), mainly occurring in women (n = 131/94.40%). Asymptomatic (n = 60/43.40%) nodules (n = 71/50.60%) were the main clinical characteristics. The lower lip represented the most affected anatomical location (n = 28/22.20%), followed by the upper lip (n = 27/21.60%). Surgical removal was the treatment of choice (n = 53/35.70%). Twelve different dermal fillers were reported in the study, and the microscopic characteristics of the cases varied according to the material used. The results based on case series and case reports showed that nodule and swelling were the main clinical characteristics of FBR related to orofacial esthetic fillers. The histological characteristics depended on the type of the filler material used.

Injectable calcium hydroxylapatite for correction of nasal bridge deformities

BACKGROUND

Minimally invasive procedures for aesthetic surgery have become widely popular, and facial soft tissue augmentation is one of the most common procedures. Various kinds of fillers have been used, and recently the use of calcium hydroxylapatite was extended to cosmetic facial procedures. This article presents the authors' experience with primary and secondary nasal bridge correction using calcium hydroxylapatite (Radiesse).

METHODS

This preliminary prospective study investigated the use of commercially available calcium hydroxylapatite (Radiesse) for correction of nasal bridge deformities. Calcium hydroxylapatite was injected on the plane of the periosteum in a retrograde fashion using a linear, threading, fanning, or crosshatching technique. The patients were followed for several months, with the outcome and side effects assessed both subjectively and objectively.

RESULTS

Patients showed a persistence of benefit up to 1 year during the follow-up period, with pleasing long-term results.

CONCLUSION

Calcium hydroxylapatite (Radiesse) is a useful injectable filler for correction of nasal bridge deformities. Further efficacy studies seem justified.
