Perioperative position management of 46 cases with simultaneous bilateral auricle reconstruction: A summary of experience.

OBJECTIVES: The primary problem in simultaneous bilateral auricle reconstruction is the fragility of the reconstructed ear structure. Postoperative pressure is strictly prohibited to ensure the operation's effectiveness. The study aimed to summarize the experience of perioperative postural management in simultaneous bilateral auricular reconstruction. METHOD: This study summarizes the experience of perioperative postural management, providing preoperative sleeping posture adaptability training, neck movement training, standardization of the head position angles and the head suspension time in surgery, using protective headrests, paying attention to the transfer and handover procedures, and using specially designed pillows. RESULTS: The comprehensive nursing approach in simultaneous bilateral auricular reconstruction significantly reduced complications, improved patient comfort, and optimized postoperative adaptation. Preoperative posture training, standardized intraoperative head positions, and vigilant postoperative care played pivotal roles, demonstrating positive outcomes in 46 cases. DISCUSSION: Perioperative position management can reduce the risk of complications and pressure injuries, improving patients' postoperative comfort, emotional state, tolerance, and adaptability. CONCLUSION: All ears were viable and in good shape after long-term follow-up. The experiences discussed in this study can be broadly applied to technically mature ear reconstruction teams.

Tunnelised superiorly based preauricular flap and conchal cartilage graft for antihelix reconstruction.

Reconstruction of a full-thickness defect of the auricle's anterior surface represents a challenge for plastic surgeons. This report describes the case of a man in his 70s, who underwent radical excision of a squamous cell carcinoma involving his right antihelix. We adopted an innovative approach for the reconstruction of the antihelix, using a tunnelled preauricular flap reinforced with an ipsilateral concha cartilage graft. The flap's base was de-epithelialised, allowing a single-stage procedure. Three months postoperation, no complications arose, and the scars at the donor site were effectively concealed. The aesthetic result was excellent, thanks to the perfect colour match, symmetry, shape of the auricle and the long-lasting integrity of the antihelical structure.This technique allows for accurate reconstruction of the convoluted surface of the auricle in cases of full-thickness defects of the antihelix, without the need to harvest cartilage from other donor sites and in a single surgical procedure.

The Auricular Injection Technique: A New Treatment for Lying Ear.

SUMMARY: Lying-ear deformity refers to an auricle that bends backward excessively, is excessively folded against the head, and has a very prominent antihelix. It usually requires experienced surgeons to perform surgical treatment and a prolonged postoperative recovery process. This article proposes a simple and effective hyaluronic acid injection technique that significantly improves the shape of the outer ear and enhances perceived facial aesthetics. Twenty patients underwent treatment with multiple injections. Measure-related parameters were used to evaluate the postoperative effect, and the results were graded using a visual analog scale. Interrater reliability among graders was evaluated using intraclass correlation coefficients. After treatment, no serious complications, such as infection or embolism, occurred. Six months after the procedure, the average auriculocephalic angle increased from 25.11 ± 9.46 to 32.72 ± 8.29 degrees, the average conchoscaphal angle increased from 87.69 ± 9.06 to 95.94 ± 7.11 degrees, and patients' average visual analog scale score increased from 4.40 ± 1.14 to 8.57 ± 0.68. Interrater reliability was fair to good for visual analog scale before injection and 6 months after injection (intraclass correlation coefficients, 0.49 and 0.45, respectively; both P < 0.001). The patients were satisfied with the injection process and results. This injection protocol improved the shape of the outer ear, resulting in excellent postoperative outcomes.

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.

Partial Central Anterior Reconstruction of the Auricle with One-Stage Combined Retroauricular Flaps.

SUMMARY: Basal cell carcinomas of the central anterior area of the auricle limited to the antihelix and scapha without peripheral infiltration of the helix are not uncommon. Resection is rarely transfixing, but resection of the underlying cartilage is often required. The complex anatomy of the ear and the lack of local tissue available makes its reparation challenging. Defects of antihelix and scapha require special reconstructive techniques, taking into account skin structure and the three-dimensional architecture of the ear. The reconstruction usually consists of full-thickness skin grafting or anterior transposition flap, requiring an extended skin resection. The authors describe a one-stage technique that uses a pedicled retroauricular skin flap turned over the anterior defect, followed by immediate closure of the donor site with a transposition or a bilobed retroauricular skin flap. The one-stage combined retroauricular flap reparation optimizes cosmetic outcome and reduces the risk of successive surgical procedures.

Reconstruction of Concha-Type Microtia Using a Delayed Postauricular Skin Flap.

SUMMARY: Understanding how to remove and retain the relatively large residual auricle is important in concha-type microtia reconstruction. The authors present a method for concha-type microtia reconstruction using a delayed postauricular skin flap. A total of 40 patients with concha-type microtia who underwent ear reconstruction using a delayed postauricular skin flap were retrospectively examined. Reconstruction was performed in three stages. The first stage consisted of preparing a delayed postauricular skin flap and dealing with the residual auricle including removal of the upper residual auricular cartilage. In the second stage, an autogenous rib cartilage framework was placed and covered with a delayed postauricular skin flap, postauricular fascia flap, and autologous medium-thickness skin graft. The ear framework was carefully articulated and secured with the retained residual auricular cartilage to achieve a smooth junction between the two. The third stage involved modification of the reconstructed ear. Patients were followed up for 12 months after ear reconstruction. All reconstructed auricles had a good appearance, and there was a smooth connection between the reconstructed auricle and the residual ear, with similar color as well as a flat and thin scar. All patients were satisfied with the results. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Question Mark Ear: An Unusual Anomaly and a Novel Surgical Technique for Reconstruction.

The question mark ear is a rare abnormality characterized by a cleft between the helix and the earlobe, resulting in a protrusion of the upper part of the ear. The severity of this ear malformation can range from a minor notch in the helix to a complete separation of the helix and the earlobe. In this study, we present a case of a patient with a moderately severe right-sided unilateral question mark deformity. To address this issue, we utilized a novel technique that involves a combination of a Y-V flap with double opposing Z-plasty. Our clinical study demonstrates that using this technique for reconstructing the deformity yields excellent results in terms of the helical rim and fold contour, utilizing solely the local tissues.

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.

Treatment of auricular pseudocysts using enhanced negative drainage: a prospective study of 21 cases.

OBJECTIVE: Auricular pseudocysts are rare, painless, benign intracartilaginous cysts of the auricle that are not lined by epithelium and have no known aetiology. METHOD: This was a prospective study conducted in an ENT department from January 2020 to June 2022. In 21 patients, complete aspiration of the pseudocyst with enhanced negative drainage was performed. They were followed for a minimum of six months. RESULTS: All patients completely responded to the negative drainage treatment. No cases of recurrence or obvious deformities were observed. CONCLUSION: Aspiration with intensified negative drainage was associated with a positive response in patients with auricular pseudocysts. Complete resolution of the swelling can be achieved without any serious complications. Thus, it appears to be a simple and effective method for managing the condition.

[3D printing in plastic surgery, an accessible tool: Technical note around a case of otopoiesis assisted by 3D model]. / L'impression 3D en chirurgie plastique, un outil accessible : note technique autour d'un cas d'otopoïèse assistée par modèle 3D.

3D printing has been used in the medical field since the beginning of the 21st century. Over the years, it has been democratized and has become an accessible tool at almost no cost, provided that a 3D printer is available. The surgeon can thus easily integrate it into his practice and techniques in the operating room, provided that he learns to use 3D image processing software. In order to illustrate the whole process, from the genesis and processing of the 3D image to its application in the operating room, we describe the case of a patient with a left auricle amputation, whose reconstruction was guided by a 3D model printed from his right ear.

Reconstruction of Upper Third Defect of the Auricle by Conchal Cartilage Graft and Coverage by Postauricular Flap.

BACKGROUND: The defects of the upper third of the auricle are considered significant reconstructive challenges, as they require frequent operations with a high risk of morbidity at the donor site and result in unacceptable cosmetic abnormalities. OBJECTIVE: Is to perform the reconstruction of a full-thickness auricular defect located in the upper third of the ear using a conchal cartilage graft with postauricular flap coverage, aiming to minimize both donor and recipient morbidity. PATIENTS AND METHODS: The current study included 20 patients with unilateral upper-third auricular defects. The repair involved 2 components: a cartilage graft from the concha to provide structural support and a flap for coverage. Follow-up was conducted for 6 months after the operation. RESULTS: Successful outcomes were achieved in both subjective and doctors' assessments. Regarding subjective outcomes, 85% of the patients reported high satisfaction (P < .001). In terms of doctors' subjective assessment, 90% of the patients had excellent results (P < .001). Mild early and postoperative complications, if encountered, resolved spontaneously. CONCLUSION: The use of a combined conchal cartilage graft and postauricular flap in treating a full-thickness upper third auricular defect is safe and effective, with no major complications. The technique preserves the cosmetic and functional outcomes of the auricle, providing an excellent color match and minimal donor-site morbidity.

Reconstruction of Full-Thickness Helical Defects Using a Superior Auricular Artery-Based Postauricular Chondrocutaneous Flap.

BACKGROUND: The helix is the most common localization of auricular defects. Various techniques have been successfully used for the reconstruction of helical defects. However, redistributing the remaining auricular tissue to supply an ideal reconstruction base provides the best possible esthetic outcomes. The aim of this study is to present a new design for a postauricular chondrocutaneous flap to reconstruct the 3-dimensional curve and the folded structures in full-thickness helical defects. METHODS: Nineteen patients with full-thickness helical defects were treated with the superior pedicle chondrocutaneous flap based on the superior auricular artery. The flap was designed on the postauricular area and comprised 3 sections, namely, deepithelialized, chondrocutaneous, and cutaneous sections (proximal to distal). Levels of patient's satisfaction on the final shape and auricular symmetry, and tissue compatibility between the flap and surrounding tissues were evaluated by the patients and objective observers. RESULTS: The overall dimensions, projections, and curved structures of the defective helix maintained a smooth and contiguous appearance without asymmetry, notching, or trap-door deformities. The color, texture, and thickness of the flaps matched well with the adjacent auricles, and there was a moderate positive correlation between patient (9.47 ± 0.51) and observer (8.68 ± 0.63) correlation scores (r = 0.7485). The vast majority of the patients were very satisfied with the surgical outcome, and there was a statistically significant improvement in patient satisfaction (mean preoperative score, 1.26 ± 0.45; mean 12-month score, 4.79 ± 0.42; P < 0.00001). CONCLUSIONS: Reconstruction of full-thickness helical defects requires "like tissue" characteristics and 3-dimensional cartilage support to avoid depression and notch deformities. The postauricular chondrocutaneous flap based on the superior auricular artery was shown to preserve the helical curve and folded sulcus, retain the size and subunits of the auricle, and ensure a color, texture, and thickness match between the flap and the adjacent tissues.

BACKGROUND: It is the challenging clinical issue of combining debridement of infected lesions and retaining the blood skin flap for auricle reconstruction in patients of Congenital Malformation of the Middle and Outer Ear with Infection (CMMOEI). AIMS/OBJECTIVES: To innovate and introduce an surgery incision to solve the challenging clinical issue of a combined debridement of infection yet retaining a well vascularized skin flap for auricle reconstruction in patients with CMMOEI. MATERIAL AND METHODS: A combined innovated incision of ear sulcus and prefabricated earlobe was used for 23 cases (23 ears) with CMMOEI, The success in the management of the encountered infections, and the short and moderate-term outcome of the innovated incision to preserve a well-vascularized skin flap for subsequent auricle reconstruction were reviewed. The 23 cases include 10 males and 13 females, aged 4-14 years (mean 8.4 years), 7 left ears and 16 right ears. 14 ears stenosis and 9 ears atresia of the outer ear canals. RESULTS: In all 23 cases, the infections were successfully cleared without recurrence or complication with 2-year follow-up. The local skin flap and its blood supply were well preserved for subsequent auricle reconstruction. CONCLUSIONS AND SIGNIFICANCE: The new incision can facilitate clearance of infection in CMOMEI patients, and preserve the retroauricular tissues for subsequent harvesting of a well-vascularized skin flap for subsequent auricle reconstruction.

Secondary ear reconstruction based on the Nagata method after unsatisfactory microtia surgery outcomes.

BACKGROUND: Follow-up studies on auricular reconstruction procedures have reported postoperative complications; some of which can only be reversed with revision surgery. This study aims to provide a feasible surgical strategy based on the Nagata method for patients requiring secondary revision and verify mid-term aesthetic outcomes. METHODS: Secondary auricular reconstructions based on the Nagata method were performed on seven patients seeking secondary revision between 2017 and 2021. Scores of a five-point Likert scale and artificial intelligence ratings based on convolutional nerve networks were used as outcome measures. RESULTS: Five patients underwent complete two-stage ear reconstruction, and the other two patients underwent the first-stage microtia procedure only. Few complications were observed, except in Case 4; this patient required an additional minor surgery after frame exposure 6 weeks after the first-stage procedure. All revised ears showed clear anatomical structures, and all patients were satisfied with the aesthetic results. Statistical analysis showed a significant increase in postoperative versus preoperative scores by convolutional neural network models (p < 0.05). Cases 5 and 6, which involved projection surgeries only, had decreased artificial intelligence appearance scores postoperatively. CONCLUSION: After adequate preoperative evaluation, secondary auricle reconstruction based on the Nagata method can achieve reliable aesthetic outcomes with few complications.

[Clinical application of retrosigmoid approach for BONEBRIDGE implantation after auricle reconstruction using expanded postauricular flap].

Objective: To explore the safety and reliability of retrosigmoid approach BONEBRIDGE implantation in patients with auricle reconstruction using skin expansion flap. Methods: A retrospective analysis was conducted on 43 congenital aural atresia cases (43 ears) who underwent BONEBRIDGE implantation from September 2019 to January 2023 in Beijing Tongren Hospital. 30 males and 13 females were included in this work. The implantation age was 9-36 years old (median age=10 y/o). All cases underwent auricle reconstruction surgery using the posterior ear flap expansion method, with 36 cases using the single expanded postauricular flap method and 7 cases using two-flap method. BONEBRIDGE implant surgery was performed during the third stage of auricle reconstruction or after all stages. The hearing improvements were evaluated by comparing the changes in pure tone hearing threshold and speech recognition rate of patients before and after BONEBRIDGE implantation. Routine follow-up was conducted to observe the hearing results and complications. SPSS 14.0 software was applied for data statistical analysis. Results: All 43 patients healed well and had no surgical complications when discharge. The average bone conduction hearing threshold after surgery was (8.2±6.6) dBHL, and there was no statistically significant difference compared to the preoperative [(8.1±5.7) dBHL] (P=0.95). After surgery, the threshold of hearing assistance with power on was significantly lower than that without hearing assistance [(32.8±4.6) dBHL vs (60.5±5.5) dBHL], and the difference was statistically significant (P<0.001). The speech recognition rate of monosyllable words, disyllabic words and short sentences in quiet environment increased to 72%, 84%, and 98% respectively. The differences were statistically significant (P<0.001). The speech recognition rate of monosyllabic words, disyllabic words, and short sentences in noise environment was significantly increased by 70%, 80%, and 92% respectively (P<0.001). After a follow-up of 4 to 47 months (median=24 months), the hearing results were stable and the aesthetic outcomes were satisfying. One patient had delayed hematoma around coil of the implant. After aspiration and compressed dressing for one week, hematoma was not recurrent. Conclusion: For patients after auricle reconstruction using expanded postauricular flap, the preference of retrosigmoid approach is a good choice in terms of safety and reliability of operation, as well as aesthetic appearance.

A novel design for prosthetic ear guiding device: A technical note.

This article describes a newly designed Prosthetic Auricular Guide (PAG) that allows for accurate planning and positioning of both the auricular implants and the prosthetic auricle. The design aims to provide a cost-effective guiding device for more esthetic ear prostheses which is the patient's main concern. Along with determining the best clinically accepted position of the ear, the device can be used while taking CBCT which allows for the integration of the clinically approved position with the remaining bone for accurate planning of implant positions. Furthermore, the device can be fixed during surgery for accurate transmission of the planned position. The device is also adjustable making it suitable for all patterns of auricular defects, different ages, and even for patients with asymmetric faces.
