To investigate whether keratinocytes proliferate in response to epiregulin produced by subepithelial fibroblasts derived from middle ear cholesteatoma. Tissue samples were obtained from patients undergoing tympanoplasty. The quantitative polymerase chain reaction and immunohistochemistry were performed to examine epiregulin expression and localization in cholesteatoma tissues and retroauricular...

INTRODUCTION  Keloids are benign tumors arising from abnormal healing of the skin, and there are several procedures available for their treatment. OBJECTIVE  The objective of this study was to evaluate the outcomes of patients undergoing treatment of keloids after ear, nose, and throat (ENT) surgeries at our service center. METHOD  We conducted thorough, retrospective and prospective analys...

BACKGROUND AND OBJECTIVES The aim of this study is to determine whether the hyperproliferative and hyperkeratotic characters of cholesteatoma are associated with differentiation of keratinocytes in cholesteatoma by examining the localization of marker proteins, such as involucrin, filaggrin, and cytokeratins. MATERIALS AND METHODS Immunohistochemical study was carried out in 30 cholesteatoma ...

A retroauricular approach is routinely used for treating chronic otitis media. The incidence of surgical site infections after ear surgery is around 10% in contaminated or dirty procedures. This observational prospective study describes surgical site infections after chronic otitis media surgery with the retroauricular approach and investigated their potential predictive factors. This observati...

The objectives of the study were to introduce and investigate the reliability of a new flap for postauricular defects using the retroauricular artery perforator.Twenty auricles from 10 Asian human cadavers were dissected to examine the retroauricular perforator distribution and diameter. Fourteen patients with postauricular defects underwent reconstruction using the retroauricular artery perfor...

BACKGROUND With the increasing use of hydroxyapatite orbital implants, the complication of exposure has become apparent to oculoplastic surgeons. Many kinds of patch grafts, such as sclera, dermis, and hard palate mucosa, have been used to cover exposed hydroxyapatite implants with inconsistent results. In this study, the authors use a newly developed technique, autogenous retroauricular myoper...

BACKGROUND The purpose of this study was to present our evaluation of the feasibility of using a retroauricular approach for excision of benign upper neck mass lesions without assistance of an endoscopic or robotic system. METHODS We enrolled 23 patients with benign neck mass lesions of the parotid gland, submandibular gland, and the level II/III region who underwent surgery via a retroauricu...

We are reporting a case of recurrent myoepithelioma of the parotid gland, that emerged as a cutaneous mass. She had a retroauricular subcutaneous mass with an underlying diagnosis of a cutaneous myoepithelioma, which was excised at a hospital's Dermatology Department 2 years earlier. The tumour was observed above the platysma and it was considered as a cutaneous myoepithelioma without the parot...

In the attempt to improve cosmetic and functional outcomes in head neck surgeries, robotic or video-assisted dissection using remote access has gained ground recent years. Retroauricular approach emerged as most versatile option, allowing proper at all levels. this technique, after retroauricular incision, a skin flap is elevated self-retaining retractor placed, creating working space for robot...
