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...

A 6-year-old boy presented to the pediatric emergency department with a unilateral 5 × 3-cm superficial mass on the postauricular region growing for 1 month. Point-of-care ultrasound was used to evaluate the mass, which revealed a complex cystic mass penetrating the temporal bone. After confirmatory magnetic resonance imaging, the patient was transferred for neurosurgical evaluation, and the tumor was excised. Pathology revealed Langerhans cell histiocytosis.

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...

Our objectives in reporting this case series are to familiarize readers with the rare occurrence of paragangliomas originating along the facial nerve and to provide a literature review. We describe 3 such cases that occurred at our tertiary care academic medical center. Two women and 1 man presented with a tumor adjacent to the vertical segment of the facial nerve. The first patient, a 48-year-old woman, presented with what appeared to be a parotid tumor at the stylomastoid foramen; she underwent a parotidectomy, transmastoid facial nerve decompression, and a shave biopsy of the tumor...

Multiple models of aberrant emotional processing in depression have been advanced. However, it is unclear which of these models best applies to emotional disturbances in subclinical depressive symptoms. The current study employed a battery of psychophysiological measures and emotional ratings in a picture-viewing paradigm to examine whether the underarousal, low positive emotion, heightened negative emotion, or emotion context insensitivity model of emotional dysfunction in subclinical depressive symptoms received greatest support...

Staged retroauricular flap is a great option for full-thickness defects along the helical rim and antihelix. Donor site consists of the posterior ear, postauricular sulcus and mastoid area. The advantages of this flap include hidden donor scar, donor tissue similarity and rich vascularity. We present a case of collision tumor on the left helix treated with Mohs micrographic surgery and the resulting full-thickness defect repaired with a staged retroauricular flap. This flap is an effective technique for full-thickness helical defect repair with relatively little operative morbidity...

OBJECTIVE: To describe the clinical manifestations of external auditory canal (EAC) cholesteatoma and evaluate the surgical outcomes of reconstruction using an inferior pedicled soft-tissue periosteum flap. MATERIALS AND METHODS: A total of 28 patients were enrolled in this retrospective study conducted at Kaohsiung Medical University Hospital in Taiwan between January 2004 and December 2013. EAC cholesteatoma was classified according to the disease extent. The surgery was performed to reconstruct a smooth contour of EAC...

We evaluated the aesthetic outcomes in 11 young patients (mean (range) age 21.7 (16-28) years) who had endoscopically assisted extracapsular dissection of benign pleomorphic adenomas of the parotid gland through a postauricular sulcus approach. The tumours varied in size from 1.5×1.0cm to 2.5×2.0cm, and all were removed completely without rupture. The cosmetic result was excellent in 10 patients and good in one. Patients were followed up for eight to 40 months, and there was no recurrence. The technique is simple and feasible, and it achieves excellent aesthetic results in young patients...

Neoplasms located in the parotid region, temporal bone, infratemporal fossa, and lateral skull base represent a challenge due to their difficult anatomic location and surrounding neurovascular structures. A variety of surgical approaches are appropriate to access this area, although several of them can place the auricular blood supply in danger. If the auricular blood supply is compromised, ischemia and, eventually, avascular necrosis of the auricle can occur. Auricular necrosis often can cause patients a delay in adjuvant radiation therapy and result in the need for additional reconstructive procedures...

If the postauricular reflex (PAR) is to be used effectively in studies of emotion and attention, its sensitivity to basic modulatory effects such as prepulse inhibition and facilitation must be determined. Two experiments were carried out with healthy young adults to assess the effects of transient and sustained visual prestimuli on the pinna-flexion response to trains of startle probes. In the first experiment, participants passively viewed a small white square. It was displayed from 1,000 ms prior to onset of a train of noise bursts until the end of that train...
