treatment and outcome of postoperative infection of rib cartilage framework in Ear Reconstruction
Chinese journal of plastic surgery, 2017Co-Authors: Hengyun Sun, Haiyue Jiang, Bo Pan, Lin Lin, Qinghua Yang, Yanyong Zhao, Jingjian HanAbstract:Objective To investigate treatment and outcome of rib cartilage framework in Ear Reconstruction. Methods 12 cases of rib cartilage framework infection in Ear Reconstruction were retrospectively analysed in the latest four yEars. Lab examination results showed that staphylococcus aureus were found in 5 cases, coagulase negative staphylococcus in 3 cases, Klebsiella pneumonia in 2 cases, aeromonas hydrophila in 1 case and no bacteria were found in 1 case with regular culture. Debridement, systemic antibiotic therapy, saline irrigations and unobstructed drainage were utilized to treat the infection. Results The average duration of dressing change was 35 days in 12 cases (12-67 days), of which six cases were cured leaving no obvious or mild change of cartilage framework. Cartilage framework was totally damaged by infection in one case, so the framework had to be removed and debridement was then carried out to control infection. Secondary repair should be taken at least 6 months later. In the rest 5 cases, frameworks were taken out in the Early stage of infection. The infected portion of the cartilage was removed and the healthy part was buried subcutaneously in the chest. The expanded postauricular flap and fascia were smoothened. Secondary repair should be performed after 6 months. Conclusions Effective debridement, irrigations and drainage can be used to control infection of cartilage framework and maintain normal contour and structure of reconstructed auricle. With regards to severe infection, framework should be removed as Early as possible and infected portion of cartilage should be clEared out, while healthy part could be used for secondary Reconstruction of auricular contour after complete control of infection.

A 2-Stage Ear Reconstruction for Microtia
Archives of facial plastic surgery, 2011Co-Authors: Haiyue Jiang, Bo Pan, Lin Lin, Yanyong Zhao, Lei Liu, Hongxing ZhuangAbstract:OBJECTIVE To introduce our 2-stage Reconstruction of microtia method, which results in a natural-looking contour of the reconstructed Ears, one of the most demanding challenges in facial plastic surgery. METHODS In the first stage, the 3-dimensional cartilage framework is fabricated. The skin flap and retroauricular fascial flap are elevated in the mastoid area. Then the framework is wrapped by the fascial flap from behind and covered by the skin flap from front. In the second stage the crus, the tragus, and the conchal cavity are reconstructed. So almost all of the fine structures of Ear are reconstructed. RESULTS Sixty-eight patients ranging in age from 5 to 17 yEars had their Ears reconstructed using our 2-stage method from January 1, 2006, to December 31, 2008. Forty-eight patients were boys, and 20 were girls. Unilateral microtia was present in 66 patients and bilateral microtia was present in 2 patients. The reconstructed Ears had a 3-dimensional configuration, and the cranioauricular angle of the reconstructed Ears was similar to that of the contralateral Ear. CONCLUSIONS Two-stage Ear Reconstruction is a simple and promising method for microtia. Furthermore, the complications are rare.

clinical evaluation of three total Ear Reconstruction methods
Journal of Plastic Reconstructive and Aesthetic Surgery, 2009Co-Authors: Yanyong Zhao, Haiyue Jiang, Yanmei Wang, Hongxin Zhuang, Wenjie Jiang, Shujie Wang, Bo PanAbstract:Summary Objective To investigate relative indications for three different surgical techniques used in total Ear Reconstruction. Methods A total of 1864 cases requiring complete Ear Reconstruction were performed. In 1485 cases Reconstruction was effected by skin expansion and subsequent grafting of autogenous rib cartilage frameworks. In 355 cases skin expansion was followed by insertion of a Medpor ® framework. Twenty-four cases were repaired with titanium dowel retained prosthesis. Clinical results of these three surgical techniques were evaluated. Results All three methods were successfully used in total Ear Reconstruction and showed a satisfactory appEarance. For patients less than 30 yEars old and with intact mastoid skin, the rib cartilage grafting methods were preferred. A Medpor ® framework was suitable for cases over 30 yEars old, despite the appEarance of mild inflammation in the skin flap. We resorted to a prosthetic Reconstruction in patients whose mastoid skin was seriously damaged when they were unwilling to accept more complex methods of Ear Reconstruction. Conclusions The three methods described provide satisfactory clinical results and are each indicated for specific patient cohorts.

ten yEar experience in microtia Reconstruction using tissue expander and autogenous cartilage
International Journal of Pediatric Otorhinolaryngology, 2008Co-Authors: Haiyue Jiang, Bo Pan, Lin Lin, Zhen Cai, Hongxing ZhuangAbstract:Summary Objective Ear Reconstruction is a complex multi-staged procedure in otology. A variety of surgical strategies have been devised for the Reconstruction. In this paper, we present our 10-yEar experience in microtia Reconstruction using tissue expander and autogenous cartilage in microtia Reconstruction. Methods The process of our method is divided into three stages. In the first stage, the kidney-shape tissue expander was implanted subcutaneously. With 1 month of inflation, the tissue expander offered the non-hairbEaring and well-vascularized skin. In the second stage, we improved the technique of cartilage fabrication and used an expanded two-flap envelope to erect framework. In the third stage, the tragus and concha were reconstructed. Results 3332 patients have undergone Ear Reconstruction using tissue expander and autogenous cartilage from 1996 to 2006. The follow-up study showed the satisfactory contour of the reconstructed Ears. Conclusions Techniques using tissue expander and autogenous cartilage in microtia Reconstruction was easily done and the complications were rare.

robot automated cartilage contouring for complex Ear Reconstruction a cadaveric study
Laryngoscope, 2020Co-Authors: Corey A Smith, Benjamin Van Der Woerd, Robert Potra, Louis M Ferreira, Corey C MooreAbstract:OBJECTIVES/HYPOTHESIS Auricular Reconstruction requiring manual contouring of costal cartilage is complex and time consuming, which could be facilitated by a robot in a fast and precise manner. This feasibility study evaluates the accuracy and speed of robotic contouring of cadaver costal cartilage. METHODS An augmented robot with a spherical burr was used on cadaveric rib cartilage. Using a laser scanner, each rib section was converted to a three-dimensional model for preoperative planning. A model Ear was also scanned to define a carving path for each piece of cartilage. After being contoured, each specimen was compared against the preoperative plan utilizing deviation maps to analyze topographic accuracy. Contouring times of the robot were compared with 13 retrospectively reviewed cases (2006-2017) by an experienced surgeon. RESULTS Scanning the cartilage sections took 24.8 ± 6.8 seconds. Preoperative processing took an additional 29.9 ± 8.9 seconds for the preparation of the contouring path. Once the path was prepared, the robot contoured the specimens with a root mean square error of 0.54 mm and a mean absolute deviation of 0.40 mm. The average time to contour the specimens with the robot was 13 ± 2 minutes compared to 71 ± 6 minutes for the manual contouring in the reviewed cases. CONCLUSIONS The accuracy of the robotic system was high, with submillimeter deviations from the preoperative plan. The robot required <20% of the contouring time compared to the experienced surgeon. This represents a fast and accurate alternative to hand-contouring costal cartilage grafts for auricular Reconstruction. Laryngoscope, 2020.

patient satisfaction and aesthetic outcomes after Ear Reconstruction with a branemark type bone anchored Ear prosthesis a 16 yEar review
Journal of Plastic Reconstructive and Aesthetic Surgery, 2010Co-Authors: Ibby Younis, Walid Sabbagh, David Gault, Norbert KangAbstract:Summary Introduction Reconstruction of the human Ear with a bone-anchored prosthesis is a widely accepted alternative when autologous Reconstruction is technically impossible or declined by the individual. However, there are relatively few data in the literature documenting patient satisfaction with this form of Reconstruction. Methods This study examines different aspects of patient satisfaction using an eighteen-point postal questionnaire to measure patient outcomes against a Likert rating scale. The questionnaire was sent to 33 patients who completed prosthetic Ear Reconstruction over a 16 yEar period at a specialist plastic surgery unit in the United Kingdom. Medical case notes for these cases were also reviewed. Twenty completed questionnaires were returned. Results The response rate was 61%. The majority of patients were satisfied with the aesthetics, ease of handling and comfort of the bone-anchored implant and prosthesis. However, the majority of patients was only moderately satisfied or was dissatisfied with this method of Reconstruction. Specifically, 15 of the respondents reported skin problems around the abutments of the bone-anchored implant with 10 patients reporting ongoing skin complications. Granulation tissue was the most common skin problem (12 cases) followed by local infection (10 cases). Interestingly, despite the chronic skin problems, most patients indicated that they would undergo the same procedure again or would recommend it to others. Discussion Our survey shows that patients fitted with a Branemark-type bone-anchored implant for Ear Reconstruction are pleased with the aesthetic appEarance but experience multiple, chronic, skin complications and other implant related problems. These affect their satisfaction with this method of Reconstruction. Our findings may have significant implications for patients and surgeons considering this form of Reconstruction and for the institutions making decisions about funding this treatment.

donor site morbidity after autologous costal cartilage harvest in Ear Reconstruction and approaches to reducing donor site contour deformity
Plastic and Reconstructive Surgery, 2008Co-Authors: Rajan S Uppal, Walid Sabbagh, Jagdip Chana, David GaultAbstract:Background: Harvesting of rib as a source of cartilage can result in significant donor-site morbidity. In experienced hands, excellent results from using autologous rib cartilage are achievable for Ear Reconstruction, rhinoplasty, and otolaryngology. The authors report the morbidity associated with the harvest of costal cartilage in 42 patients who underwent Ear Reconstruction. Methods: The notes were examined retrospectively and further data were collected with a questionnaire. Patients noted their experience of pain, clicking, and satisfaction with the donor site. Fifteen patients underwent additional clinical assessments of their donor scar and contour deformity using a standardized scale. Five donor sites were reconstructed with spare cartilage left over from carving the Ear framework. Results: The results showed that pain and clicking of the chest wall represented the commonest complaints. These peaked in the first week after surgery and diminished slowly over 3 months. The donor-site scar and deformity were acceptable to most patients. There was an improvement in the contour deformity of the chest wall harvest site in the five patients who underwent Reconstruction of their donor site. Conclusions: To improve the outcome for patients undergoing cartilage harvest, efforts must be made to further reduce pain and donor-site morbidity. Reconstruction of the donor site with spare cartilage should be attempted where possible to improve the contour defect of the donor site. Refinements in the methods of cartilage harvest or donor-site Reconstruction may achieve this in the future.

piercing the upper Ear a simple infection a difficult Reconstruction
British Journal of Plastic Surgery, 2002Co-Authors: Silvia Cicchetti, Joanna Skillman, David GaultAbstract:Piercing the upper Ear to retain jewellery is now commonplace. When infection ensues, devastating chondritis leads to collapse of the Ear. To our knowledge, the surgical Reconstruction of post-piercing deformities has not been documented in the literature. We present five such cases referred for autogenous-tissue Ear Reconstruction. In four of these, the destroyed segments of Ear cartilage were replaced with a carved costal-cartilage framework. One patient declined surgery. The importance of preventing infection is stressed.

microtia Ear Reconstruction using tissue expander and autogenous costal cartilage
Journal of Plastic Reconstructive and Aesthetic Surgery, 2008Co-Authors: Bo Pan, Haiyue Jiang, Dongjun Guo, Chenyu Huang, Hongxing ZhuangAbstract:Summary Ear Reconstruction is one of the most challenging surgeries faced by the reconstructive surgeon. Currently, the use of autogenous costal cartilage is still best practice for microtia Reconstruction. However, the relative deficiency of thin skin for coverage of the cartilage framework remains a limiting factor. Since 1994, we have used tissue expander in the mastoid area and innovated a technique to fabricate cartilage framework. All these innovations may solve the deficiency of the skin and improve cartilaginous framework definition. In conclusion, tissue expander offers a non-hairbEaring, thin, well-vascularised skin to envelope an erect, contour-accentuated framework. Most patients with microtia are satisfied with their Ear Reconstruction.

Chinese journal of plastic surgery, 2006Co-Authors: Hongxing Zhuang, Haiyue Jiang, Bo Pan, Qinghua Yang, Yanyong Zhao, Juan HanAbstract:OBJECTIVE To explore surgical procedure of congenital microtia. METHODS Ear Reconstruction was made using soft tissue skin expander and autogenous rib cartilage framework. RESULTS Long time follow-up showed that the flap of reconstructed Ear was ruddy, soft, with normal sensory function; cartilage framework had no degeneration, absorption and deformation. In addition, the reconstructed Ears were coincidence with the normal side on location, form and dimension. CONCLUSIONS It was a good method for congenital microtia to use soft tissue skin expander together with autogenous rib cartilage framework at present time.
