Bakri MM, Lee SH, Lee JH. Improvement of biohistological response of facial implant materials by tantalum surface treatment. Maxillofac Plast Reconstr Surg 2019; 41:52. [PMID: 31824890 PMCID: PMC6879676 DOI: 10.1186/s40902-019-0231-3] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2019] [Accepted: 09/24/2019] [Indexed: 01/24/2023] Open
Abstract
Background A compact passive oxide layer can grow on tantalum (Ta). It has been reported that this oxide layer can facilitate bone ingrowth in vivo though the development of bone-like apatite, which promotes hard and soft tissue adhesion. Thus, Ta surface treatment on facial implant materials may improve the tissue response, which could result in less fibrotic encapsulation and make the implant more stable on the bone surface. The purposes of this study were to verify whether surface treatment of facial implant materials using Ta can improve the biohistobiological response and to determine the possibility of potential clinical applications. Methods Two different and commonly used implant materials, silicone and expanded polytetrafluoroethylene (ePTFE), were treated via Ta ion implantation using a Ta sputtering gun. Ta-treated samples were compared with untreated samples using in vitro and in vivo evaluations. Osteoblast (MG-63) and fibroblast (NIH3T3) cell viability with the Ta-treated implant material was assessed, and the tissue response was observed by placing the implants over the rat calvarium (n = 48) for two different lengths of time. Foreign body and inflammatory reactions were observed, and soft tissue thickness between the calvarium and the implant as well as the bone response was measured. Results The treatment of facial implant materials using Ta showed a tendency toward increased fibroblast and osteoblast viability, although this result was not statistically significant. During the in vivo study, both Ta-treated and untreated implants showed similar foreign body reactions. However, the Ta-treated implant materials (silicone and ePTFE) showed a tendency toward better histological features: lower soft tissue thickness between the implant and the underlying calvarium as well as an increase in new bone activity. Conclusion Ta surface treatment using ion implantation on silicone and ePTFE facial implant materials showed the possibility of reducing soft tissue intervention between the calvarium and the implant to make the implant more stable on the bone surface. Although no statistically significant improvement was observed, Ta treatment revealed a tendency toward an improved biohistological response of silicone and ePTFE facial implants. Conclusively, tantalum treatment is beneficial and has the potential for clinical applications.

Permanent implants for lip augmentation: Results from a retrospective study and presentation of tips and tricks. J Plast Reconstr Aesthet Surg 2017; 70:699-704. [PMID: 28336448 DOI: 10.1016/j.bjps.2017.02.005] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2016] [Revised: 01/16/2017] [Accepted: 02/17/2017] [Indexed: 11/26/2022]
Abstract
BACKGROUND Requests for lip augmentation are increasing because of expanding media exposure and consumer needs. Temporary effects can be obtained by several techniques, but a recent procedure consisting of lip prosthesis implantation, offering a permanent result, is emerging. Accordingly, the implantation of solid lip prosthesis represents an innovation in the field of esthetic medicine and surgery. METHODS A total of 100 women with atrophic or hypoplastic lips were treated with lip implants. The treatment was performed in a single session, and controls were scheduled at fixed time intervals. A standard digital photo was used for measurement and analysis. Data concerning patient satisfaction and complications of the technique were collected and analyzed. Variations to the original technique were also discussed. RESULTS Patient evaluation revealed that a permanent and natural result without discomfort for the patient and/or the partner was reached with the implantation of silicone prosthesis in the upper and/or lower lip. Swelling, bruising, and malpositions were the most frequent adverse events. A case of severe edema was reported. Practical tricks acquired through experience were discussed to prevent complications. CONCLUSIONS One of the most widespreading methods for lip remodeling is hyaluronic acid injections. Nevertheless, hyaluronic acid has a variable duration, and it is not always the first choice. This context allowed for the development of other techniques such as the implantation of silicone prosthesis. The advantages of this prosthesis are as follows: safety, definitive result, and reversibility considering the possibility to remove the implanted prosthesis in the case of a request.

Abstract
Expanded polytetrafluoroethylene (ePTFE) has been extensively used for facial soft tissue augmentation procedures, and is regarded as safe and reliable and suitable as a permanent implant. This implant is generally used in the lower third of the face for lips filling, nasal augmentation, nasolabial folds and chin augmentation, and rarely for congenital or acquired depressed deformities of the face. The aim of the present study was to assess the effects of ePTFE in congenital or acquired depressed deformities of the face. From September, 2008 to January, 2014, 26 patients were implanted with the material ePTFE to correct depressed deformities of the face. The average age at operation was 23.2 years, with a range of 17-45 years. The depressed deformities were lateralized. The follow-up period was 6-18 months (average 9 months). The etiologies of the depressed deformities included stable hemifacial atrophy (3 cases), craniofacial microsomia (13 cases), bony depression after trauma (8 cases), and other unclear reasons (2 cases). The operations were performed under local anesthesia. ePTFE was inserted in different tissue planes that varied among the different subanatomical areas in the face: beneath the superficial temporal fascia in the temporal area, and on the surface of the superficial musculoaponeurotic system in the zygomatic area, cheek and mandibular area. All of the patients were followed up. Most of the patients [25 of 26 patients (96.2%)] were satisfied with the results, while 1 patient (3.8%) was not satisfied for incomplete correction of the depressed deformity. In conclusion, aside from lipofilling and a free flap transfer, the results showed that ePTFE was an alternative treatment for facial depressed deformity.

Systematic review of "filling" procedures for lip augmentation regarding types of material, outcomes and complications. J Craniomaxillofac Surg 2015; 43:883-906. [PMID: 25957105 DOI: 10.1016/j.jcms.2015.03.032] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2015] [Revised: 03/25/2015] [Accepted: 03/26/2015] [Indexed: 11/20/2022] Open
Abstract
BACKGROUND The ideal lip augmentation technique provides the longest period of efficacy, lowest complication rate, and best aesthetic results. A myriad of techniques have been described for lip augmentation, but the optimal approach has not yet been established. This systematic review with meta-regression will focus on the various filling procedures for lip augmentation (FPLA), with the goal of determining the optimal approach. METHODS A systematic search for all English, French, Spanish, German, Italian, Portuguese and Dutch language studies involving FPLA was performed using these databases: Elsevier Science Direct, PubMed, Highwire Press, Springer Standard Collection, SAGE, DOAJ, Sweetswise, Free E-Journals, Ovid Lippincott Williams & Wilkins, Willey Online Library Journals, and Cochrane Plus. The reference section of every study selected through this database search was subsequently examined to identify additional relevant studies. RESULTS The database search yielded 29 studies. Nine more studies were retrieved from the reference sections of these 29 studies. The level of evidence ratings of these 38 studies were as follows: level Ib, four studies; level IIb, four studies; level IIIb, one study; and level IV, 29 studies. Ten studies were prospective. CONCLUSIONS This systematic review sought to highlight all the quality data currently available regarding FPLA. Because of the considerable diversity of procedures, no definitive comparisons or conclusions were possible. Additional prospective studies and clinical trials are required to more conclusively determine the most appropriate approach for this procedure. LEVEL OF EVIDENCE IV.

Abstract
BACKGROUND Expanded polytetrafluoroethylene implants have been used successfully for augmentation of thinning lips, deep nasolabial folds, and marionette lines without the risk, recovery time, and expense of major surgery. OBJECTIVE The objective was to assess long-term results and patient satisfaction with expanded polytetrafluoroethylene implants. MATERIALS AND METHODS A retrospective chart review was performed on all patients treated with expanded polytetrafluoroethylene implants from January 1, 2001, to July 1, 2002. RESULTS Eighty-five implants were placed in 33 patients. Forty-six percent of implants were placed in the nasolabial folds, 34% in the lips, 16.5% in the marionette lines, 2% in the oral commisures, and 1% in the glabella. Eighty-seven percent of implants remain in place with excellent correction. Eleven implants in 6 patients were removed. Four of the 11 implants removed were considered too small by the patient and were replaced with larger implants without difficulty. The other reasons for implant removal included malposition, localized swelling, and an unnatural feel. Patient and physician satisfaction with the treatment was high. CONCLUSION Expanded polytetrafluoroethylene implants are a safe, effective, and permanent option for facial volume augmentation. Patients who have had their implants in place for 5 years or more continue to report high satisfaction with the treatment. The authors have indicated no significant interest with commercial supporters.
