The Ram Graft: Using One Complete Piece of Conchal Cartilage for Nasal Tip Reconstruction in East Asians.

SUMMARY: Adequate nasal tip projection remains a challenge in aesthetic rhinoplasty for East Asians. Various surgical techniques have been developed to reshape the nasal tip using auricular cartilage. In this article, we introduce the new ram graft to increase nasal tip projection by using one complete piece of conchal cartilage. Between 2019 and 2021, 19 patients who underwent nasal tip reconstruction using ram grafts were reviewed in a single hospital. The complication rate, satisfaction rate, and changes in nasolabial angle and nasal proportion were recorded. Nineteen patients with a mean age (± SD) of 28.9 ± 6.1 years underwent nasal tip reconstruction. The mean follow-up time was 15.4 ± 6.6 months. Nasolabial angle increased from 87.4 ± 10.0 degrees to 91.2 ± 10.2 degrees ( P > 0.05). Sixteen of 19 patients (84.2%) were satisfied with their results. The nasal length-to-nasal tip projection-to-dorsal height-to-radix height ratio is 2:0.8:0.62:0.19 preoperatively and 2:0.92:0.77:0.35 postoperatively. Complications including alloplast-related infection (two of 19) and septal extension graft-related decrease of nasal tip projection (one of 19) were recorded. By using one complete piece of conchal cartilage, the ram graft is a simple and effective approach to increase nasal tip projection for East Asians. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Application of 3D printing in ear reconstruction with autogenous costal cartilage: A systematic review.

PURPOSE: In recent years, 3D printing technology has been employed as a production method that builds materials layer upon layer, providing notable advantages in terms of individual customization and production efficiency. Autologous costal cartilage ear reconstruction has seen substantial changes due to 3D printing technology. In this context, this research evaluated the prospects and applications of 3D printing in ear reconstruction education, preoperative planning and simulation, the production of intraoperative guide plates, and other related areas. METHODOLOGY: All articles eligible for consideration were sourced through a comprehensive search of PubMed, the Cochrane Library, EMBASE, and Web of Science from inception to May 22, 2023. Two reviewers extracted data on the manufacturing process and interventions. The Cochrane risk of bias tool and Newcastle-Ottawa scale were used to assess the quality of the research. Database searching yielded 283 records, of which 24 articles were selected for qualitative analysis. RESULTS: The utilization of 3D printing is becoming increasingly widespread in autogenous costal cartilage ear reconstruction, from education to the application of preoperative design and intraoperative guide plates production, possessing a substantial influence on surgical training, the enhancement of surgical effects, complications reduction, and so forth. CONCLUSION: This study sought to determine the application value and further development potential of 3D printing in autologous costal cartilage ear reconstruction. However, there is a lack of conclusive evidence on its effectiveness when compared to conventional strategies because of the limited number of cohort studies and randomized controlled trials. Simultaneously, the evaluation of the effect lacks objective and quantitative evaluation criteria, with most of them being emotional sentiments and ratings, making it difficult to execute a quantitative synthetic analysis. It is hoped that more large-scale comparative studies will be undertaken, and an objective and standard effect evaluation system will be implemented in the future.

Optimal surgical timing for ear reconstruction with autologous cartilage: Analysis of the computed tomography scan characteristics of the ribs.

BACKGROUND: The approach to constructing the cartilage framework for ear reconstruction is sufficiently established. However, there is still no consensus about the age of initiation of surgical treatment. This study aims to assess the development and growth of the costal cartilage to determine the best age to perform ear reconstruction surgery. METHODS: Out of 107 patients, we used presurgical treatment data for 40 patients and medical records for 67 patients aged 5-40. Computed tomography (CT) scans were performed, and average parameters were calculated (length, width, thickness, cartilage density, and standard deviation in Hounsfield units) of the cartilaginous part of the 6th, 7th, 8th, and 9th ribs. RESULTS: The required values were reached at 9-10 years old. CONCLUSION: The criteria for starting surgical treatment in the Russian population was determined by the width of the 6th-7th ribs synchondrosis, which must be equal to the width of a healthy auricle, and the length of the 8th rib should be longer than 9 cm. Therefore, the optimal age for ear reconstruction with autologous costal cartilage is 10 years and older. However, reconstruction can be made earlier in specific cases, according to height and weight and the preoperative CT scan.

Brent Technique of Repair Versus Nagata Auricular Reconstruction for Microtia Reconstruction: A Systematic Review and Meta-Analysis.

BACKGROUND: Up to 17.4 in every 10,000 births are affected by microtia, but no consensus exists on a gold standard technique for autogenous repair. In this study, the authors compare 2 common methods-the Brent and Nagata autogenous costal cartilage ear reconstruction techniques. A systematic review of the literature and a quantitative meta-analysis to compare the outcomes of these 2 approaches were performed. The outcomes analyzed included rates of infection, necrosis, cartilage exposure, cartilage resorption, hematoma, wire extrusion, and hypertrophic scar. METHODS: A MEDLINE database systematic review with the following keywords: microtia, Brent, and Nagata was performed. Case reports and articles without original data or patient outcomes were excluded. Inclusion methods for study selection are outlined in Supplemental Digital Content 1, http://links.lww.com/SCS/F461 , below. The prevalence of outcomes for each study was analyzed through meta-analysis of proportions using Stata. RESULTS: A total of 536 potential studies were retrieved for review. Twelve of these studies met inclusion criteria. Four studies utilized the Brent method of repair with the inclusion of 563 ear reconstructions. Nine studies implemented the Nagata technique in 2304 reconstructions. Two studies directly compared the Brent (327 ears) and Nagata (471 ears) techniques. The calculated rate and 95% confidence intervals are summarized in Supplemental Digital Content 2, http://links.lww.com/SCS/F461 . There were no statistically significant differences in complication rates between the Brent and Nagata microtic reconstruction techniques identified in this study. CONCLUSIONS: The Brent and Nagata microtia reconstruction techniques have no difference in the risk of infection, necrosis, cartilage exposure, cartilage resorption, hematoma, wire extrusion, or hypertrophic scars.

Comparison of Polypropylene and Polydioxanone in the Hemitransdomal Suture: A Novel Rabbit Ear Cartilage Model.

BACKGROUND: Lower lateral cartilage reshaping is one of the basic steps in rhinoplasty. Hemitransdomal suture is frequently used for dome narrowing. Different suture materials can be used for hemitransdomal suture. In this study, we investigated the effectiveness of polypropylene and polydioxanone in hemitransdomal suture by designing a new experimental model in the rabbit ear cartilage. METHODS: Twelve young adult male New Zealand White rabbits were used. The bipedicled inverted-U-shaped cartilage was elevated in each ear of the rabbits. Two hemitransdomal sutures were applied using 5-0 polypropylene on one ear and 5-0 polydioxanone on the other ear randomly. A 5 mm high cartilage mound was created with two hemitransdomal sutures on each side. The sample size was twelve both in the polypropylene group and the polydioxanone group (n = 12). All animals were sacrificed after three months. Cartilage mound heights were measured. The samples were examined histologically regarding fibroadipose tissue, inflammation, foreign body granuloma, cartilage degeneration, and the presence of inclusion cyst. RESULTS: Cartilage mound height was significantly higher in the polypropylene group than in the polydioxanone group at the end of the third month [3.75 mm (± 0.68) vs. 3.03 mm (± 0.69); p < 0.05]. There was no significant difference between the two groups in histological analysis (p > 0.05). CONCLUSIONS: Polypropylene suture may be more effective in maintaining the shape given to the dome by hemitransdomal sutures in rhinoplasty.

Combining bioengineered human skin with bioprinted cartilage for ear reconstruction.

Microtia is a congenital disorder that manifests as a malformation of the external ear leading to psychosocial problems in affected children. Here, we present a tissue-engineered treatment approach based on a bioprinted autologous auricular cartilage construct (EarCartilage) combined with a bioengineered human pigmented and prevascularized dermo-epidermal skin substitute (EarSkin) tested in immunocompromised rats. We confirmed that human-engineered blood capillaries of EarSkin connected to the recipient's vasculature within 1 week, enabling rapid blood perfusion and epidermal maturation. Bioengineered EarSkin displayed a stratified epidermis containing mature keratinocytes and melanocytes. The latter resided within the basal layer of the epidermis and efficiently restored the skin color. Further, in vivo tests demonstrated favorable mechanical stability of EarCartilage along with enhanced extracellular matrix deposition. In conclusion, EarCartilage combined with EarSkin represents a novel approach for the treatment of microtia with the potential to circumvent existing limitations and improve the aesthetic outcome of microtia reconstruction.

Total rebuilding of the ear after unsatisfactory initial microtia reconstruction: 30-year experience using autogenous costal cartilage framework.

BACKGROUND: This study describes the author's experience with long-term follow-up analysis of secondary procedures in patients with unsatisfactory initial microtia reconstruction. METHODS: A total of 134 patients who underwent secondary operations between 1992 and 2021 were reviewed by examining medical records and photographic data. A total of 110 patients followed between 6 months and 26 years (average 33.2 months) were included for evaluation of aesthetic outcomes. RESULTS: Primary reconstruction was performed with costal cartilage in 113 patients, porous polyethylene implant in 7 patients, silicone implant in 6 patients, and others in 8 patients. The major external features at the time of the secondary reconstruction were lump (91 cases), deficient convolution (19 cases), and no framework with scarred mastoid skin (22 cases). All secondary reconstructions were performed with an autogenous costal cartilage framework. The framework was covered using temporoparietal fascia flap techniques in 118 patients, mastoid skin coverage technique in 12 patients, and others in 4 patients. One major complication (exposure of cartilage framework due to partial necrosis of fascial flap) and three minor complications (loss of moderate-sized full-thickness skin, grafted on the fascia) were recorded. The average score given for aesthetic outcomes, rated on a four-point Likert scale (i.e., 1 = poor, 2 = fair, 3 = good, and 4 = excellent) was 3.17 (median 3.00). A total of 42% of the patients were rated excellent and 36% were rated good.

Application of Auricular Cartilage-Skin Graft in the Reconstruction of Unilateral Cleft Lip Nasal Deformity.

BACKGROUND: Autologous cartilage grafts are increasingly used in the treatment of cleft lip nasal deformity, but nasal alar retraction caused by lining defects often occurs after surgery. We designed a new graft to treat unilateral cleft lip nasal deformity while avoiding nasal alar retraction. METHODS: Nineteen patients in our hospital underwent unilateral cleft lip nasal deformity repair surgery with an auricular cartilage-skin graft. The effect of surgery was evaluated in four aspects: satisfaction with postoperative appearance, nasal aesthetic subunit indices, position of the nasal alar rim and three-dimensional spatial difference. RESULTS: Overall satisfaction with each index was above 90%. The nasal tip angle and nasolabial angle of patients were significantly smaller after surgery than before surgery (P < 0.01). The height of the nostril on the affected side and the length of the nasal columella were greater after surgery than before surgery (P < 0.01). The spatial differences in soft tissue between the unaffected side and the affected side after surgery were significantly smaller than before surgery (P < 0.01). According to the follow-up results of 1-2 years, there were no significant retraction of the nasal alar rim (P > 0.05) and no obvious auricular deformity. All patients had a noticeable improvement in their nasal appearance. CONCLUSION: The auricular cartilage-skin graft, which can not only improve the appearance of the nose but also avoid nasal alar retraction, is an ideal graft to cure unilateral cleft lip nasal deformity.

A Scarless Method for Correcting Tanzer Group IIB-Constricted Ear Without Cartilage Grafting.

Tanzer group IIB-constricted ear is described as a deformity of the helix, antihelix, or scapha. Deficiency of the auricular skin and cartilage is a key point in the reconstruction of the cartilaginous framework. Traditionally, the treatment of a constricted ear mainly includes 2 aspects: correction of cartilage deformity and restoration of skin volume deficiency. By mimicking the suspension principle of a cable bridge, our technique only requires adjustment of the spatial directions and mechanical forces between the 2 flaps to achieve an aesthetic effect. The authors were able to avoid harvesting the costal cartilage. The desired ear shape was obtained immediately postoperatively. Therefore, Vaseline gauze was not applied and was modeled along the scapha and antihelix. Expansion of the ear was remarkable in both horizontal and vertical lengths. Our technique causes less damage, less scarring, shorter operation time, fewer complications, faster rehabilitation, and no delays.

An Innovative Stent Consisting of Expanded Polytetrafluoroethylene and Ear Cartilage in Rhinoplasty For Asians: Application I of Dai's Exogenous Extension Stent Concept.

BACKGROUND: Restricted ventilation is common after rhinoplasty with an endogenous extension stent. The authors proposed an exogenous extension stent concept for Asian rhinoplasty patients to avoid this problem. Herein, we introduce an innovative stent in rhinoplasty for Asians, which is an application of this concept. METHODS: An L-shaped expanded polytetrafluoroethylene is hand-carved, and the long arm is placed at the nose back to improve the flatness of the nose, while the short arm supports the nasal column to raise the nose tip. The prosthesis does not occupy nasal volume and therefore theoretically does not affect nasal ventilation. The fan-shaped ear cartilage was placed at the nasal tip to prevent visualization of the nasal tip. The safety and effectiveness of this method were verified through 20 years of clinical practice. The difficulty of learning and popularizing the method was tested through the course of rhinoplasty among 22 plastic surgeons. RESULTS: After 20 years of clinical practice, it was found that this stent could not only effectively improve the nasal dorsum and tip morphology, but also did not actually affect the nasal volume and thus did not affect the nasal ventilation of patients. Among the trainees in plastic surgery, we found that it was not difficult to learn this method of rhinoplasty and the trainees could complete the prosthesis carving well after standardized training. CONCLUSION: This stent consisting of expanded polytetrafluoroethylene and ear cartilage is suitable in rhinoplasty for Asians with significant advantages, one of which is that it has no risk of resulting in restricted nasal ventilation. LEVEL OF EVIDENCE: Level IV.

The Promise of Regenerative Medicine in the Reconstruction of Auricular Cartilage Deformities.

There are many physiologic and psychologic challenges associated with ear cartilage deformities which are incredibly distasteful to patients, particularly children. The development of regenerative medicine (RM) sciences has opened up a new window for the reconstruction of auricular cartilage because it allows the creation of a structure similar to the auricular in appearance and function. As part of this review, we discuss the role that each RM tool, including tissue engineering, cells, and biomolecules, plays in developing engineered auricular tissue. In previous studies, it was shown that the simultaneous use of natural and synthetic biomaterials as well as three-dimensional printing techniques could improve the biological and mechanical properties of this tissue. Another critical issue is using stem cells and differentiated cartilage cells to produce tissue-specific cellular structures and extracellular matrix. Also, the importance of choosing a suitable animal model in terms of handling and care facilities, physiologic similarities to humans, and breed uniformity in the preclinical assessments have been highlighted. Then, the clinical trials registered on the clinicaltrials.gov website, and the commercialized product, called AuriNovo, have been comprehensively explained. Overall, it is important to provide engineered auricular cartilage structures with acceptable safety and efficacy compared with standard methods, autologous cartilage transplantation, and prosthetic reconstruction in RM.

Bioengineered human tissue regeneration and repair using endogenous stem cells.

We describe a general approach to produce bone and cartilaginous structures utilizing the self-regenerative capacity of the intercostal rib space to treat a deformed metacarpophalangeal joint and microtia. Anatomically precise 3D molds were positioned on the perichondro-periosteal or perichondral flap of the intercostal rib without any other exogenous elements. We find anatomically precise metacarpal head and auricle constructs within the implanted molds after 6 months. The regenerated metacarpal head was used successfully to surgically repair the deformed metacarpophalangeal joint. Auricle reconstructive surgery in five unilateral microtia patients yielded good aesthetic and functional results. Long-term follow-up revealed the auricle constructs were safe and stable. Single-cell RNA sequencing analysis reveal early infiltration of a cell population consistent with mesenchymal stem cells, followed by IL-8-stimulated differentiation into chondrocytes. Our results demonstrate the repair and regeneration of tissues using only endogenous factors and a viable treatment strategy for bone and tissue structural defects.

A reinforced framework construction technique using unilateral auricular cartilage in Asian rhinoplasty to prevent long-term nasal tip drooping.

BACKGROUND: Enhancing nasal tip projection is an important objective in Asian rhinoplasty. Nasal tip enhancement using auricular cartilage is simple and suitable for Asian patients. However, the long-term retraction problem of the auricular framework still needs to be solved for optimal results. OBJECTIVES: The authors propose a modified auricular cartilage framework construction technique that provides stronger long-term support to the nasal tip and columellar base. METHODS: Eighty-one patients underwent augmentation rhinoplasty between January 2016 and December 2019. The cymba and cavum conchae were harvested from one ear in all cases. The cymba concha was carved and folded to form a caudal septal extension graft (CSEG). The cavum concha was divided into an integrated cap/shield graft and a columella base graft. The columella base graft was diced into particles in size of 1 mm3, and inserted into the gap between CSEG, anterior nasal spine, and the medial crus to strengthen the foundation. The nasal profile was analyzed before the operation and at least 12 months after the operation. The patient satisfaction score was assessed 12 months after surgery. RESULTS: Patients were followed up for 12-36 months. The nasal tip projection from both the lateral and basal views was significantly improved. The columella-labial angle was increased from 83.15° (6.20°) to 96.50° (7.40°) (p < 0.05). The nostril tip proportion increased from 0.83 (0.14) to 1.17(0.16) (p < 0.01). A stable long-term outcome was achieved. CONCLUSIONS: With the modified framework construction technique, long-term nasal tip drooping can be prevented. This method can be a practical choice for Asian patients seeking augmentation rhinoplasty.

Application of Auricular Cartilage Scaffold Combined With L-Shaped Prosthesis in Asian Rhinoplasty.

Rhinoplasty is a common surgical procedure in medical cosmetology. From patients with saddle nose deformity to beauty seekers with low and short noses, this surgery is mainly sought to improve the nose's appearance. To investigate the effect of modified auricular cartilage scaffold combined with L-shaped prosthesis in rhinoplasty. This retrospective study included 54 patients who underwent auricular cartilage augmentation rhinoplasty with L-shaped implants in our hospital from July 2018 to July 2021. The function of nasal ventilation and olfaction was inspected. As a result, the degree of nasal tip protrusion and the changes in the superior lip angle of columella were improved. The patients' satisfaction was measured a year after the surgery. Patients who underwent auricular cartilage augmentation rhinoplasty with L-shaped prosthesis were satisfied with the surgery outcomes. Using a protective auricular cartilage scaffold combined with an L-shaped implant for augmentation rhinoplasty reduced the shortage of the application and reinforced the stability of the auricular cartilage augmentation rhinoplasty. At >12 months follow-up, there were no serious adverse effects on nasal ventilation and olfactory function in any of the patients. The presented method made full use of auricular cartilage so that it reduced the harvest of the cartilage. Besides, it achieved the remarkable lift of the nose tip, thus simulating the appearance of costal cartilage rhinoplasty. Furthermore, the risk of implant exposure was efficiently reduced, making it worthy of clinical application.

Short-Term Outcomes of Modified Boston Type-II Keratoprosthesis Implantation With Autologous Auricular Cartilage Reinforcement.

PURPOSE: To report the short-term visual outcomes and complications of a modified Boston Type-II keratoprosthesis (Kpro) procedure. DESIGN: Retrospective case series. METHODS: Thirty-seven eyes of 37 patients who had an implantation of autologous auricular cartilage-reinforced (AACR) Boston Type-II Kpro (BK2) were included in the current study. Preoperative and postoperative data were recorded and analyzed for each eye. Main outcome measures included best-corrected visual acuity, symptoms as assessed by questionnaires, complications associated with implantation, and retention of the implanted BK2 device. RESULTS: A total of 37 eyes, consisting of 19 with severe autoimmune dry eye (ADE) and 18 with burn injury, completed ≥12 months of follow-up. The median (interquartile range) best-corrected visual acuity at baseline, 1 month, 3 months, 6 months, 1 year, and 2 years of follow-up was hand motion (HM) 20/60 (20/100-20/40), 20/60 (20/200-20/40), 20/60 (20/200-20/40), 20/100 (20/200-20/40), and 20/100 (20/400-20/40), respectively. All eyes retained the initial device (37/37, 100%). Common postoperative complications included retroprosthetic membrane (n = 21), de novo glaucoma (n = 7), endophthalmitis (n = 1), and conjunctival erosion (n = 4). No ear complications were discovered during follow-up assessments. The ocular surface disease index score improved from baseline to a 2-year follow-up (median 57.5 vs 21.43). CONCLUSION: The modified AACR-BK2 procedure could be considered to restore vision in patients with end-stage corneal blindness.

An Optimizing Surgical Procedures for Correcting Severe Constricted Ears: Helix Costal Cartilage Scaffold Combined With V-Y Advanced Flap.

PURPOSE: A constricted ear is a deformity that is distinguished by curling of the upper portion of the ear, which includes the helix, scapha, and antihelix. The treatment for severely constricted ears seems to be quite invasive. To reduce invasiveness and fully utilize the folded cartilage, the authors used a helix costal cartilage scaffold combined with a single V-Y advanced flap in the correction of Tanzer type IIB constricted ear deformity to investigate the clinical effect. MATERIALS AND METHODS: From 2020 to 2021, autologous costal cartilage helix stent combined with local V-Y advanced flap was applied to correct the constricted ear malformation in 18 patients admitted to the Plastic Surgery Hospital of the Chinese Academy of Medical Sciences. RESULTS: All patients were followed for a duration of 6 to 12 months (average 7 months). Reconstructed auricles were cosmetically satisfying, with a natural-looking helix and enlarged cavum conchae cavity, as well as auricle sizes that were close to normal and near symmetry between both ears. CONCLUSIONS: With satisfactory clinical results, our technique can be used to repair types IIB cup ear deformities. It has a broad range of practical applications.

Primary Ear Reconstruction Using Cadaveric Costal Cartilage.

OBJECTIVE: Allogeneic cadaveric costal cartilage is commonly used for grafts in nasal reconstruction surgery; however, limited information exists on its use in total ear reconstruction for microtia. In this case series, we describe the novel use of cadaveric cartilage for auricular framework construction in ear reconstruction and review preliminary histologic findings. METHODS: Patients requiring primary complete reconstruction of the auricle from August 2020 to December 2021 were eligible and underwent ear reconstruction using cadaveric costal cartilage. Patients were evaluated for surgical site infection, skin necrosis, cartilage resorption, and cartilage exposure during regular follow-up visits. Two cartilage samples were taken after 2 separate second-stage surgeries done 52 weeks after first-stage reconstruction. These samples were stained with hematoxylin and eosin as well as safranin-O and examined under light microscopy. RESULTS: A total of 12 ear reconstruction procedures using cadaveric costal cartilage were performed across 11 patients; 10 of 12 ears had type III microtia and 2 of 12 ears had type IV microtia. Patients ranged from 4 to 25 years old at the time of surgery, with an average age of 10.7 years. Follow-up time ranged from 1.6 to 25.4 months, with a mean follow-up time of 11.2 months. No patients experienced any visibly significant cartilage warping. Two patients experienced minor construct exposure, which were successfully salvaged. Two patients experienced surgical site infections, one lead to resorption requiring framework replacement. Preliminary histologic analysis of the 2 samples taken 1 year after implantation showed viable chondrocytes with no evidence of immunologic rejection or any local inflammation or host foreign body response. CONCLUSIONS: Cadaveric costal cartilage serves as a viable alternative to autologous cartilage and other alloplastic biomaterials for construction of auricular frameworks in primary microtia reconstruction. Resorption secondary to infection and construct exposure remain potential risks. Longer follow-up times and a larger sample size are needed for assessment of long-term efficacy.

Vertical mattress suture applied as "tension band fixation" for the antihelix creation and prominent ear treatment: 104 case reports.

BACKGROUND: Prominent ears were the most common auricular deformity. Different surgical techniques, such as cartilage-cutting techniques and suturing techniques, are available for treatment. The horizontal mattress suture technique, represented by the Mustard technique, is widely accepted, while the vertical mattress suture technique is rarely discussed in otoplasty. METHOD: A total of 104 cases of prominent ear deformities were treated from January 2017 to December 2020. Several hypothetical "tension bands" perpendicular to the natural curvature of the antihelix were introduced for the surgical design and determination of the position of the antihelix fixation, and vertical mattress sutures were placed accordingly for the auricular cartilage fixation. RESULT: Follow-up ranged from 3 months to 2 years. No complications, such as hematoma, infection, or poor wound healing, were observed. Three patients had recurrence within two months post operation, and one complained about the overfolded antihelix. Three cases had suture exposure, but the shape of the auricle was not affected after suture removal. The surgical result was evaluated according to the overall shape of the auricle, including the shape of the antihelix, the improvement of the prominent, the surgical marks, and the bilateral symmetry. A total of 98 patients (94.23%) rated the results as "very satisfactory" or "satisfactory". CONCLUSION: The vertical mattress suture applied as "tension band fixation" could provide stable cartilage fixation with the natural appearance of the antihelix formation. In addition, the technique could fit a wide range of indications with a low risk of complication and reoccurrence.
