OBJECTIVE: Since the 1950s, microscopic myringoplasty has been the standard surgery for repairing a perforated tympanic membrane. In addition to conventional microscopic myringoplasty, endoscopic myringoplasty has been an emerging technique since the late 1990s. This study evaluated the efficacy of endoscopic transcanal myringoplasty for repairing tympanic perforations and examined the minimally invasive feature of this technique (no postauricular incision, no canalplasty). METHODS: We retrospectively reviewed the medical records of patients who underwent endoscopic transcanal myringoplasty for perforations of the tympanic membrane...

Periauricular paresthesia may afflict patients for a significant amount of time after facelift surgery. When performing face and neck lift surgery, temple and posterior auricular flap dissection is undertaken directly over the auriculotemporal, great auricular, and lesser occipital nerve territory, leading to potential damage to the nerve. The auriculotemporal nerve remains under the thin outer superficial fascia just below the subfollicular level in the prehelical area. To prevent damage to the auriculotemporal nerve and to protect the temporal hair follicle, the dissection plane should be kept just above the thin fascia covering the auriculotemporal nerve...

BACKGROUND AND OBJECTIVES: Epidermoid and dermoid cysts are benign cystic lesions, lined by ectodermal squamous epithelium. They are not common in the head and neck areas, which constitute ~7% of all cases of epidermoid and dermoid cysts. The aim of this study was to investigate the clinical characteristics of epidermoid and dermoid cysts that developed around the ear. SUBJECTS AND METHODS: The clinical records were retrospectively reviewed for patients confirmed histologically as idiopathic epidermoid and dermoid cysts of the ear from January 2011 to December 2015...

OBJECTIVE: We have recently proposed a hypothesis that acid leakage through the cholesteatoma epithelium mediates bone resorption in middle ear cholesteatoma. In the present study, we investigated the expressions of transient receptor potential vanilloid (TRPV) channels, which have been shown to play roles in the regulation of epidermal barrier function, in the cholesteatoma epithelium in comparison with the normal skin. METHODS: Cholesteatoma epithelium and postauricular skin were collected from 17 patients with primary acquired middle ear cholesteatoma who underwent tympanomastoidectomy...

Bone wax is an effective hemostatic agent that generally is considered safe. However, because it is nonabsorbable, significant complications can occur. We present the first two reported cases of delayed migration and extrusion of bone wax through postauricular wounds due to foreign body reaction and granuloma formation following mastoid surgery. We also present a literature review of complications associated with intraoperative bone wax use and discuss alternative hemostatic agents. Laryngoscope, 2017.

The human hip bone is generally accepted as the most reliable bone for sex estimation in forensic and bioarchaeological disciplines. However, it is seldom completely preserved. The best preserved region is typically around the sacroiliac joint and its auricular surface; it is therefore surprising that this surface has not been involved in standard sexing methods. The aim of this study was to explore the shape and size sexual dimorphism of the auricular surface in detail and to compare its sex estimation accuracy using the geometric morphometric (GM) and traditional methodological approach...

AIM: The purpose of this study was to evaluate skin permeation and penetration of nonivamide which has been formulated in novel film-forming formulations (FFFs). These formulations aim to prolong the availability of capsaicinoids which are used in long-term treatment of chronic pruritus. METHODS: An oily solution of nonivamide was loaded into porous silica particles which then were suspended in an aqueous dispersion of a sustained release polymer. Permeation and penetration experiments were performed ex vivo with postauricular porcine skin using modified Franz diffusion cells...

CONCLUSIONS: The heparin-binding epidermal growth factor-like growth factor (HB-EGF) plays an essential role in the development and invasiveness of cholesteatoma. This study may help to realize the molecular mechanisms underlying the pathogenesis of cholesteatoma and make HB-EGF a promising target for drug intervention of cholesteatoma. OBJECTIVE: To detect HB-EGF expression in human surgical specimens of acquired middle ear cholesteatoma and analyze its functional role as a regulator of epithelial keratinocytes hyperproliferation...

Langerhansmporal histiocytosis (LCH) refers to a group of diseases that are characterized by the primary pathogenesis of an abnormal polyclonal proliferation of Langerhans cells that affect different structures of the human body, including the temporal bone. Thus far, the etiology of LCH remains unclear. Diagnosis of LCH is based on a synthetic analysis of the clinical presentations, as well as on features of imaging and histopathology. The clinical features, diagnosis, treatment and prognosis of LCH remain obscure, and temporal LCH is often confused with ear inflammatory lesions and malignant tumors...

INTRODUCTION: The lenticular process of the incus succumbs to necrosis in chronic otitis media. Few researchers have addressed the issue of autograft incus preservation in the soft tissue of the tragus or mastoid cavity. Nonetheless, preservation of the incus in this method during the second stage of ossiculoplasty is a subject that is still up for debate. This study was carried out to demonstrate the hearing outcome after a modification of the incus interposition technique, which involved preserving it in the periauricular soft tissue...

OBJECTIVES: Endoscopic transcanal myringoplasty is a newly-introduced technique for reconstruction of tympanic membrane perforation that offers the advantage to obviate postauricular incision. The objective of this study was to evaluate the feasibility of a double-handed endoscope holder transcanal myringoplasty in children. This technique permits bimanual execution of the procedure and allows the surgeon to overcome the two significant issues of single-handed endoscope surgery, i.e. easy domination of a bloody field and smooth introduction of the graft...

Introduction Benign paroxysmal positional vertigo is a generally benign condition that responds to repositioning maneuvers and frequently resolves spontaneously. However, for some patients it can become a disabling condition in which surgery must be considered. Two different surgical techniques exist, singular neurectomy and posterior semicircular canal occlusion. Objective The objective of this study is to review the current status of singular nerve section and posterior semicircular canal occlusion as treatments for intractable benign paroxysmal positional vertigo, and to determine if there are published data available that favors one over the other...

BACKGROUND: This article presents a new microtia reconstruction method using a delayed postauricular skin flap. METHODS: The surgery is scheduled in three stages, the first of which delays the postauricular skin flap and deals with the remnant auricle. Three weeks later, the second stage is carried out. An erect, three-dimensional ear framework fabricated from autogenous rib cartilage is inserted between two flaps. The anterior auricular surface of the framework is draped with the delayed skin flap, and the postauricular surface is draped with postauricular fascia and overlying grafted skin...
