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...

Ear protrusion is the primary indication for otoplasty. Many methods have been developed for addressing this defect, based on cartilage-scoring/excision and suture-fixation techniques. However, disadvantages include either irreversible distortion of the anatomy, irregularities, or overcorrection; or forward bulging of the conchal bowl. One of the most common long-term sequelae of otoplasty is an unsatisfactory result. A novel, cartilage-sparing, suture-based technique has been developed that aims to minimize the risk of complications and provide a natural-appearing aesthetic result...

Nonsurgical correction of congenital auricular deformity is known to be effective in newborns. In this study, the authors investigated factors influencing the outcome of nonsurgical or surgical correction of the auriculocephalic sulcus, an important auricular structure and one that is necessary for wearing glasses or a mask. A total of 80 ears (63 children) were splinted using a metallic paper clip and thermoplastic resin in our outpatient clinic between October 2010 and September 2019. The ears were divided into a group, in which the auriculocephalic sulcus was formed nonsurgically (n =5 6) and a group, in which surgery was needed (n = 24)...

UNLABELLED: Approximately 5% of the population has protruding ears. An antihelix deficiency or absence is a common cause of ear protrusion. Although there are over 200 techniques to manage prominent ears, there is no evidence to support using dermabraders in this situation. To the author's knowledge, this is one of the first articles to assess the clinical outcome of dermabrader use on patients with prominent ear deformities. METHODS: An analysis of retrospective medical records was conducted by the senior author on patients with prominent ears treated with our novel dermabrasion technique between 2018 and 2021...

BACKGROUND: Despite a number of surgical procedures for the reconstruction of moderate to severe constricted ears described in the literature, a most cost-effective method remains to be explored. It is still a challenge to maximize the full use of the ear cartilage and surrounding skin while achieving the best results. METHODS: From 2011 to 2016, seven constricted ear patients were enrolled in this study. Five of them were moderate (type IIB Tanzer classification) deformities, and two were severe (type III Tanzer classification)...

The auricle is a complex anatomic structure with a three-dimensional configuration proper reinstating that poses a substantial reconstructive challenge. The postauricular pull-through flap is perfectly suitable method for the reconstruction of helical and antihelical auricle defects; however, due to its difficult harvest technique, it is not commonly used in a practice. Here we describe a case of a patient with an antihelix defect following basal cell carcinoma (BCC). In our case, the reconstruction was performed via postauricular pull-through pedicle flap, and a satisfactory result was achieved...

INTRODUCTION: Prominent ear is 1 of the most common congenital deformities of the ear. Incidence is reported as approximately 5%. This deformity can classically be the result of antihelix insufficiency, overprojection of concha or combination of both. Less frequently, folded or overprojectile ear lobule can aggravate the deformity. Surgical techniques can be aimed at concha, antihelix formation, lobule positioning. In our study, postoperative results for the combination of suture otoplasty and perichondrioadipodermal flap techniques in prominent ear surgery is discussed in light of the recent literature...

One of the most common complications of total auricular reconstruction is exposure of the ear framework. Various reconstruction methods have been reported depending on the location and size of exposed cartilage. This report describes a safe reconstruction method for each exposed part of the grafted ear framework. From January 2019 to August 2021, 2 cases (4 areas) of framework exposure were observed following autologous microtia reconstruction. The first case developed 2 small areas of skin necrosis on the anterior helix and lower antihelix to concha...

Convolutional neural networks are increasingly used in the medical field for the automatic segmentation of several anatomical regions on diagnostic and non-diagnostic images. Such automatic algorithms allow to speed up time-consuming processes and to avoid the presence of expert personnel, reducing time and costs. The present work proposes the use of a convolutional neural network, the U-net architecture, for the segmentation of ear elements. The auricular elements segmentation process is a crucial step of a wider procedure, already automated by the authors, that has as final goal the realization of surgical guides designed to assist surgeons in the reconstruction of the external ear...

Keloids are skin lesions which result from an aberration in the physiological healing process marked with overgrowth of collagen fibers. Keloid of the ear is cosmetically challenging and has an increased chance of re-growth. To minimize recurrence, pressure therapy in combination with other treatment forms has been used. Various techniques have been used to fabricate a passive or active stent. This report presents a fully digital workflow to fabricate an ear stent after intralesional excision and skin autografting of an extensive recurrence of a keloid lesion of the left ear involving the helix, antihelix, scapha, and conchal bowl...
