          Abstract

          BACKGROUND

          Filler materials are gaining popularity in nonsurgical rhinoplasty the major advantages are the ability to camouflage the surface deformities, and also the soft and malleable consistency; while the major drawback of the safe fillers such as hyaluronic acid is short durability. In this study, we evaluated the injectable cartilage shaving as an autologous filler material for correction of minor contour deformities in rhinoplasty.

          METHODS

          Injectable cartilage shaving was used for correction of surface irregularities in primary or secondary rhinoplasty, and long term results of 128 patients were evaluated. The source of cartilage was autologous septum, rib or less frequently, the ear concha. The material was injected with 14 to 18 gauge needles or blunted tip lipofilling cannulas with 1.3-1.7 mm internal diameters. It was performed whether during the septorhinoplasty or as a separate single procedure without elevation of the flap. Success was defined as the long term survival of the graft in the desired site and absence of recurrent deformity or complications such as extrusion, infection or displacement.

          RESULTS

          Twenty seven males and 101 females underwent the procedure from May 2008 to January 2014. Mean follow up period was 31 (13-58) months. Ninety five percent of patients were satisfied or very satisfied with the results at the last follow up visits and touch up procedure was performed for the unsatisfied patients.

          CONCLUSION

          Injectable cartilage shaving is a reliable filler to correct and camouflage the surface irregularities, and it is durable and predictable in long term follow ups.

            Diced cartilage grafts in rhinoplasty surgery.

            K Daniel, John Calvert (2004)
            The use of diced cartilage grafts in rhinoplasty surgery was recently revived by Erol with the publication of his technique for "Turkish delight" grafts (i.e., diced cartilage grafts wrapped in Surgicel). The present study details the authors' experience with 50 consecutive diced cartilage grafts used in three configurations during a prospective study of 50 primary and secondary aesthetic rhinoplasty procedures performed by the senior author (Daniel). Part I consists of 22 diced cartilage grafts wrapped in Surgicel and placed in the radix (n = 14), radix/upper dorsum (n = 4), and full-length dorsum (n = 4). All grafts were performed adhering meticulously to Erol's technique without modification. This portion of the study was halted abruptly at 4 months because of the unexpected absorption and clinical failure of all diced cartilage grafts wrapped in Surgicel. Subsequently, five patients had revision surgery, and biopsy specimens were taken at the prior grafting site and analyzed histologically. After this clinical failure, part II of the study began, consisting of 20 patients who had diced cartilage grafts wrapped in fascia. The range of applications was comparable: radix (n = 12), radix/dorsum (n = 3), and full-length dorsum (n = 5). Because of our prior practice of overcorrecting by 20 percent with diced cartilage grafts wrapped in Surgicel, we had excessive amounts of material in six of our initial diced cartilage wrapped in fascia radix grafts, but no subsequent grafts. The overcorrections were easily reduced at 6 weeks to 11 months postoperatively using a pituitary rongeur under local anesthesia, and the material was sent for histologic analysis. Minimum 1-year follow-up of all 20 cases has shown maintenance of the grafts without evidence of absorption. Part III of this study comprised eight patients who had diced cartilage grafts without a fascial covering placed throughout the nose, including on the sides of osseocartilaginous rib grafts to the dorsum. At 14 months, there was no evidence that any of these grafts had been absorbed. Histologic analysis of the biopsy specimens from the diced cartilage grafts wrapped in Surgicel showed evidence of fibrosis and lymphocytic infiltrates with small amounts of Surgicel visible on birefringent microscopy. Remnants of cartilage were present but were metabolically inactive on the basis of negative glial fibrillary acidic protein staining. Control specimens of fresh septal cartilage and banked septal cartilage were remarkably similar to each other and demonstrated normal cartilage architecture and cellular activity. The diced cartilage grafts wrapped in fascia showed coalescence of the diced cartilage into a single cartilage mass, with viable cartilage cells and normal metabolic activity on the basis of glial fibrillary acidic protein staining. All of the diced cartilage grafts wrapped in Surgicel absorbed and failed to correct the clinical problem for which they were performed. All of the diced cartilage grafts wrapped in fascia and pure diced cartilage grafts did correct the clinical deformities and appear to have survived completely. The diced cartilage grafts wrapped in fascia placed along the dorsum were distinctly palpable throughout the postoperative period, as was one prior case with a 6-year follow-up. The authors' clinical experience confirms the experimental studies of Yilmaz et al. that question the use of Surgicel for wrapping diced cartilage grafts in clinical rhinoplasty surgery.

              Injectable hyaluronic acid gel for soft tissue augmentation. A clinical and histological study.

              M Calandra, F Duranti, L Rosati … (1998)
              Several biomaterials are available for the purpose of soft tissue augmentation, but none of them has all the properties of the ideal filler material. The recent development of hyaluronic acid gels for dermal implantation give the physician new possibilities of effective treatment in this field. This study provides a clinical and histological evaluation of safety and efficacy of a cross-linked stabilized non-animal hyaluronic acid gel (Restylane, Q-Med, Uppsala, Sweden) to determine its characteristics, advantages, disadvantages, and side-effects. 158 patients were treated with facial intradermal implant of hyaluronic acid gel for augmentation therapy of wrinkles and folds, and for lip augmentation and/or recontouring. The results were evaluated in all patients by subjective judgement by the physician and the patient, and by photographic method at time 0 and after 1, 2, 4 and 8 months from the procedure. In addition, a smaller histological study was carried out in five volunteer patients for a term of 52 weeks to determine the interaction and duration of the material in human healthy skin. Clinically, both the physicians' and patients' evaluations revealed very satisfactory results, with a global 78.5% and 73.4% respectively of moderate or marked improvement after eight months, independent of the treated area. The photographic evaluation revealed even better results with a 80.4% of moderate or marked improvement after 8 months. The safety evaluation showed a 12.5% of postoperative immediate adverse events, that were localized and transient. There was no evidence of major systemic side effects. Histologically, the product was shown to be long-lasting and well tolerated as judged by histological techniques. Stabilized, non-animal, hyaluronic acid gel is well tolerated and effective in augmentation therapy of soft tissues of the face. This material presents several advantages in comparison to previously used injectable biomaterials and expands the arsenal of therapeutic tools in the field of soft tissue augmentation.
