Nasal dorsum grafts are carefully stitched, filled, and fixed to maximize predictability. | An extension of the septal cartilage dorsum border is fixed to the septal cartilage graft to increase nasal dorsum height. Surgical outcomes and operative courses were analyzed for patients the senior author treated with this operative technique. Case examples illustrate the indications and outcomes of the procedure. | Patients with under-projected noses can benefit from this grafting technique by improving functionality, defining dorsal aesthetic lines, and achieving a more balanced profile. | [4]/2023 |
A rabbit model was used to investigate using a HA matrix as an allograft. | Eight rabbits were osteotomized. Four animals underwent a sham operation as a control group, while four received a saline-gelled HA matrix and cartilage slices. | DA rhinoplasty may be improved with the HA matrix. Membranous ossification was accompanied by collagen development; however, complete ossification requires more time. | [35]/2023 |
Using this improved method, the authors assessed the safety and efficacy of augmentation rhinoplasty in these patients. | During the study, 52 thin-skinned Asian noses with modified perichondrium on dorsal onlay grafts underwent open augmentation rhinoplasty. Evaluation of aesthetic outcomes was performed using the ROE scale. | In long-term follow-up, ROE scores were statistically different before and after surgery. Approximately 97% of patient satisfaction was reported during and after surgery on the ROE scale, while 20.65% were reported as satisfied postoperatively. A high satisfaction rate was reported by patients for the nasal dorsal improvement using the VAS questionnaire. Fat liquefaction and warping occurred at the donor site, but no other serious complications occurred. The best method to conceal the nasal dorsum of thin-skinned patients is to perform an onlay DA rhinoplasty with perichondrium covering both edges of the graft. | [36]/2023 |
This study examines and illustrates his experience and outcomes in performing primary and revision rhinoplasty with PAFG. | Several prospective bicentric studies were conducted on patients with slight dorsal deficiencies undergoing rhinoplasty following hump resections, trauma, or previous rhinoplasty. After surgery, MRIs were used to measure graft resorption objectively. ROE scores were compared preoperatively and 1-year postoperatively to investigate patient satisfaction. Pair-wise t-tests were used to compare scores following normal distributions. | Rhinoplasty done with PAFG is reliable for minor augmentation and camouflaging of the dorsal aspect. Only a small amount of learning is required for the procedure. | [7]/2023 |
This study investigated how buried thread nasal augmentation affects the dorsal soft tissue of the nose and the result of revision rhinoplasties. | Patients requested revision rhinoplasty after buried thread nasal augmentation. A polytetrafluoroethylene expansion was used for revision rhinoplasty in the rest of the patients; autologous rib cartilage and alar cartilage were used to reshape the tip of the nose in 16 cases, and autologous septal cartilage and alar cartilage in 10 other cases. | The subcutaneous tissue of the nasal dorsum is impacted by soft tissue compliance after implantation of the absorbable thread. Absorption and degradation of the thread stimulate inflammatory cells and fibroblasts to move into the surrounding tissue and cause scarring, which can affect revision rhinoplasty design and outcome. | [37]/2023 |
Secondary rhinoplasty with cross-linked ADM was investigated for surgical outcomes and complications. | Between 2015 and 2018, the authors prospectively examined 56 patients who underwent secondary rhinoplasty in their clinic. Silicone implants, capsules, scar tissue removal, ADM dorsal augmentation, and autogenous cartilage tip plasty were performed in all cases. Preoperatively, 6 months postoperatively, and over one year postoperatively, the Modified Rhinoplasty Outcome Evaluation was used to assess outcomes. | After primary rhinoplasty, ADM cross-linked human DA and autogenous cartilage nasal tip work can resolve various problems caused by silicone implants. The surgical outcome was favorable, with a low infection rate, firm implant attachment, good skin texture/thickness, and gain of desired height and dorsal line. | [38]/2023 |
Clinical and 3D morphometric analyses were conducted to determine if septal extension grafts improved nasal and tip deformity and achieved a standard profile. | An analysis of 194 consecutive cases of unilateral cleft was performed. The septal extension graft was used in all secondary open rhinoplasty procedures between 2013 and 2021. A 3D morphometric measurement and clinical data were collected. | In this study, researchers found a significant improvement in deformities of the under-projected, up-rotated, deviated, and poorly defined nasal tips and nose bridges. Patients with cleft lip nasal deformities could benefit from the technique by having a nose more like a normative nose. | [39]/2023 |
UDCWF graft resorption rate and thin rib cartilage graft stability were measured. | The number of patients who underwent septal extension grafting and nasal dorsum augmentation between 2017 and 2020 was 53. Before, immediately after, and after surgery, three-dimensional photogrammetry was used to measure nasal tip height, sellion height, and nasolabial angle. | Instability and rotation were both maintained by thin rib cartilage. For Asians with thick skin and short noses, it is an effective alternative to rhinoplasty. The UDCWF graft also showed a resorption rate of approximately 7.5%, meaning a lower probability of stepping and dorsal irregularities. | [15]/2023 |
Primary and secondary cases aimed to achieve ideal dorsal aesthetic lines rather than adding volume with fascia and DC-F. | Four configurations of DC-F grafts were used in this study: double layer, single layer, partially filled DC-F, and full-length DC-F grafts. To prevent graft displacement, dimensions were carefully determined and sutured to the dorsum at 10 points. | It was possible to conceal irregularities in the nasal dorsum, highlight aesthetic lines, and enhance the look of nasal parts using autogenous deep temporal fascia, rectus abdominis fascia, and DC-F. Nasal dorsum grafts are carefully stitched, filled, and fixed to maximize predictability. | [40]/2022 |
Rhinoplasty can be camouflaged and augmented using cartilage chips, reveals this study. | The study analyzed 64 cases of rhinoplasty that were performed from 2014 to 2019. A total of 49 rhinoplasties were performed, with 15 revisions. Cartilage chips were cut into smaller pieces from 2 to 10 mm thick. They were used to fill deep radix depressions around the grafts and prevent them from being visible at the tip. The fascia was also augmented with them. Forty-six cartilage chips, 16 rib chips, and 1 ear chip were sculpted from septal cartilage. | Using cartilage chips as a camouflage and augmentation method is proving very effective. | [41]/2022 |
This study used ADM to compare the effectiveness of DA rhinoplasties performed as a primary procedure versus a revision procedure. | A retrospective cohort study design was used to recruit DAR patients operated on by a single surgeon over 65 months. Postoperative changes in dorsal and radix heights compared to nasal length were the primary outcomes, as well as patients’ and surgeons’ satisfaction with results on both aesthetics and function. Demographic, surgical, and pathological variables were grouped into three categories. | Although patients in this study differed significantly in age, the number of osteotomies and tipplasties, and hump reduction surgeries, ADM was found to be a safe and effective option for primary and revision DAR. | [42]/2022 |
Alloplastic dorsum augmentation surgery is the subject of these meta-analyses. | Duplications were removed, and 491 titles and abstracts remained. Observational studies, retrospective studies, and case series were included. The systematic review and meta-analysis included 3803 cases. | PTFE, HDE, and silicone were the most widely used alloplasts. Using a random effects model, the revision rate was 6.40% with 95%CI. | [23]/2022 |
Analyzing long-term complications after diced cartilage grafting for DA rhinoplasty | Infection, overcorrection, visible irregularities, absorption, and revision rates were pooled in a meta-analysis. | DA rhinoplasty complications are presented for the first time in this meta-analysis. A common complication was infection. A diced cartilage packing method did not correlate with irregularity and revision surgery. | [43]/2022 |
This study examined an autologous material that doesn't disperse for use in dorsal nasal augmentation. Resorption, warping, and wrapping membrane resistance are significant for this material. | An ear concha cartilage and perichondrium with fascia were removed from 30 patients. A posterior soft tissue attachment was used to say the concha cartilage. DA material was being developed. | This technique uses diced cartilage attached to the perichondrium for onlay nasal augmentation. A shell cartilage with a peculiar shape can make a flexible, versatile, and durable material. | [44]/2022 |
An investigation will be made into the indications, sites, techniques, complications, and patient satisfaction with temporalis fascia grafts in rhinoplasty. | From 2015 to 2020, the King Abdulaziz University Hospital in Saudi Arabia conducted this retrospective cohort study. Different forms of temporalis fascia were predictor variables. In addition to satisfaction, irregularities in the dorsal nasal region and contour definitions were reported. The reason for surgery, the surgical type, graft size, and surgery site were also considered. DA findings have been evaluated by a doctor other than a surgeon. | As a preferred nasal reconstruction material for rhinoplasty, the temporalis fascia is superficial to harvest and can be shaped in various ways. | [45]/2022 |
Researchers present here a new comma-shaped columellar strut graft design. Grafts serve multiple functions, including supporting the tip, modifying angles, and influencing the columella-tip relationship. | In total, 78 patients had primary cases; the rest had secondary cases. Comma strut and spreaders were used to reconstruct the cartilaginous framework. | Providing reliable support for the nasal tip, the comma strut defines the lobular-columellar angle and modifies the supratip break. | [46]/2021 |
Researchers present a unique technique for reconstructing Mohs defects using diced cartilage grafts and folded paramedian forehead flaps. | Recurrent basal cell carcinoma of the nose presented in a 54-year-old female who had been previously resected three times. A through-and-through nasal defect was achieved with Mohs surgery. An underlying paramedian flap was folded and staged. To enhance the dorsal area, diced cartilage, and fibrin glue were used with temporalis fascia to reconstruct the supratip break. | A paramedian forehead flap was used for nasal reconstruction using a diced cartilage graft. Rebuilding and defining the nasal dorsum can be accomplished with this technique. | [47]/2021 |
Bilateral septal extension struts are a new graft design. Two cartilage grafts are bilaterally fixed to the septum in a fan shape. An extension graft and a columellar strut are combined to form a “sandwich” structure. | Augmentation rhinoplasty using bilateral septal extension struts was performed on 52 female patients, ages 18 to 37. | Overall, patient satisfaction with the nose improvement was high based on their evaluations. Graft extrusion or infection was not reported. Long-term follow-up revealed severe asymmetry in two revision cases due to columellar deviation and warped dorsal onlay grafts. Strut graft warping can be mitigated with bilateral septal extension struts, making it easier to manage. Long-term support is provided to the lateral cartilages at the tip and lower end. | [48]/2021 |
Researchers compared outcomes for septorhinoplasty patients receiving autologous cartilage, IHCC, and Tutoplast grafts. | Consensus resolved conflicts after a dual review of abstracts and full texts. Ensure homogeneity of the study sample by including only patients undergoing en bloc dorsal onlay grafts. Five hundred seventy-six unique citations remain after removing duplicates. | In rhinoplasty patients undergoing dorsal augmentation, no differences in outcomes were observed in warping, infection, contour irregularity, resorption, or revisions between homologous and autologous costal cartilage grafts. In augmentation rhinoplasty, dorsal onlay grafts provide the nasal dorsum with structure and contour. | [49]/2020 |
Using objective and subjective assessment criteria, researchers compared aesthetic outcomes and complications of MCG with those of OCGs. | The DA of 82 consecutive patients was performed by a single surgeon using OCG or MCG. An anthropometric analysis and a consensus decision were used to determine the aesthetic outcomes. Additionally, postoperative complications and patient satisfaction were examined. | When MCG is used for dorsal augmentation, the aesthetic results are similar, but there is a lower rate of warping than when OCG is used. For Asian rhinoplasty, MCG might be an effective alternative to graft warping in nasal dorsal augmentation. | [27]/2020 |
A septal extension graft combined with mild rasping could be an alternative approach. | From March 2012 to July 2015, patients who had hump nose correction with rhinoplasty were recruited for this retrospective study. In limited cases, researchers used smooth dorsal contouring instead of conventional DA after humpectomy. A three-dimensional photogrammetric analysis was performed on 15 patients. | It is, therefore, more meaningful to balance the nasal tip and nasal dorsum after hump resection in Asians than to augment the dorsum. | [14]/2020 |
Comparing dice cartilage wrapping with temporalis fascia and alloderm for DA of the nose was the purpose of this study. | They randomly assigned 50 patients who needed nasal augmentation to two equal groups in a clinical trial. Diced cartilage was wrapped using temporalis fascia in the first group and a thin sheet of alloderm in the second. Two groups of patients and experts were surveyed after one year. Two groups were also compared on mean dorsal height increase. | In augmentation of the nasal dorsum, temporal fascia was more effective than alloderm in covering diced cartilage. A temporal fascia group had higher patient satisfaction and mean dorsal height. | [50]/2020 |
In a novel method of dorsal augmentation, the researcher combined autologous costal grafts with septal extension grafts. | This study retrospectively reviewed 28 records of augmentation rhinoplasty performed using their novel technique. In addition, researchers have shown the use of septal extension grafts to augment bony dorsums and cartilaginous dorsums. To evaluate surgical outcomes, 15 facial photographs were analyzed for anthropometric parameters. | All nasal parameters were successfully augmented. All patients had a mobile and comfortable nasal tip. Twelve patients were delighted, ten were satisfied, and six needed revision surgery. Due to visible or warped solid septal extension grafts, ten patients had caudal deviations. In Asian patients, it is possible to maximize DA by using autologous costal grafts combined with septal extension grafts in augmentation rhinoplasty. | [51]/2019 |
Patients with a history of rhinoplasty were evaluated for the effectiveness of closed reduction versus conservative treatment of nasal bone fractures. | Among 17 patients who underwent rhinoplasty for nasal bone fractures, five underwent a closed reduction, and 12 underwent a conservative procedure. The esthetic improvement of three of 12 conservatively treated patients was achieved with secondary rhinoplasty. Based on the modified Murray classification, all patients were classified based on fracture site and presence of a nasal septal fracture, and their disease course was analyzed. | The risk of traumatic capsular rupture is minimal, and closed reductions are recommended only when visible deviations exist. | [28]/2019 |
The researchers described their primary and secondary experiences with diced conchal cartilage wrapped in retroauricular fascia. | Nineteen patients with this technique had their clinical records reviewed. The entire shell was harvested and diced using the same incision, then wrapped in retroauricular fascia. The mastoid dead space was closed with quilting resorbable sutures. Researchers have used the graft in all cases using a closed approach. | Dorsal augmenting with diced cartilage has become one of the most popular procedures. With posterior auricular fascial graft, diced conchal cartilage can be wrapped and reattached to the ear without a secondary donor site, which speeds up the process and conceals the scar. Even when bilaterally harvested, costal diced cartilage wrapped in rectus abdominis fascia has several disadvantages, including a smaller amount of cartilage and a more prolonged postoperative swelling than temporal fascia. | [25]/2019 |
The researchers used soft tissue filler to examine the dorsal nasal artery course in patients undergoing nasal enhancement. They proposed a nasal augmentation method that minimizes vessel damage by confirming blood vessel distribution patterns through ultrasound before injecting soft tissue filler. | Patients had augmentation rhinoplasty using soft tissue filler. Injections of filler were performed under ultrasound examination. | There is a possibility of vascular compromise when injecting the filler through a needle or cannula into the pre-periosteal layer. The safest approach may be injecting the filler into the preperiosteal layer using a large cannula. | [52]/2019 |
Patients with nasal bone fractures who received rhinoplasty and fracture reduction concomitantly were examined for surgical techniques and outcomes. | Three major types of nasal bone fractures can be distinguished based on computed tomography and preoperative facial images. Two otolaryngologists evaluated The surgical outcomes independently after a telephone survey was conducted to assess patients' satisfaction. | In acute nasal bone fracture cases, concomitant rhinoplasty with fracture reduction may result in better aesthetic results. | [53]/2018 |
In this study, the authors sought to determine if osteotomy was available and safe for East Asian patients undergoing esthetic rhinoplasty. | The retrospective chart review was done for 227 patients who had undergone nasal osteotomies and silicone implants. Rhinoplasty Outcome Evaluation tested patient satisfaction after surgery. A cadaveric study also involved an osteotomy on each side of the nose on 5 fresh cadavers. | Percutaneous lateral osteotomies and paramedian oblique osteotomies effectively reduce broad nasal bones, thus allowing for reliable augmentation with silicone. | [54]/2018 |
The objective is to develop tools that can be used to objectively evaluate the necessary dimensions for a customized-glue-diced cartilage construct for dorsal augmentation. | Researchers used the ACAS to modify diced cartilage glue. | Compared to diced cartilage glue, this technique is superior. Alloplastic implants look similar to the shape with varying heights and widths. For a more natural look, the cephalic and caudal ends taper. Improved aesthetic lines at the brow tip. | [55]/2018 |
