conclusions primary scec is a rare and highly aggressive tumor. however, prognosis is poor and long-term survival is exceptional. crt could be an appropriate alternative to operation. patients and methods this brief report was carried out by reviewing the medical records of 22 patients with newly histologically proven scec that were treated between 2000 and 2010 at 2 tertiary academic hospitals...

acute left atrial thrombosis at the site of the resection of the primary cribriform septum is an exceedingly rare and important complication after atrial septal defect (asd) closure with a pericardial or synthetic patch. this case report presents a mobile thrombus noted on the left atrium at the raw surface site of a resected cribriform primary septum that was not caught in the suture line with...

OBJECTIVES Middle ear surgery can affect gustatory function because of the course of the chorda tympani nerve (CTN) close to the tympanic membrane. The aim of the study was to evaluate the sense of taste before and after middle ear surgery with a test suitable for clinical routine. Moreover, subjective complaints were assessed over a relatively long period of time. METHODS Forty-seven patient...

Image-guided robots have been widely used for bone shaping and percutaneous access to interventional sites. However, due to high-accuracy requirements and proximity to sensitive nerves and brain tissues, the adoption of robots in inner-ear surgery has been slower. In this paper the authors present their recent work towards developing two image-guided industrial robot systems for accessing chall...

We studied the efficacy of granisetron, a selective 5-hydroxytryptamine type-3 receptor antagonist, in preventing postoperative nausea and vomiting (PONV) after middle ear surgery. In a randomized, double-blind, placebo-controlled study, 60 ASA I patients received placebo (saline) or granisetron 40 micrograms kg-1 i.v. immediately before induction of anaesthesia (n = 30 in each group). A standa...

A 19-yr-old female, 48 kg, was admitted to a hospital for left middle-ear surgery. Her medical history, physical examination and laboratory evaluation were normal. Anesthesia was induced with fentanyl 1 μg/kg, thiopental 5 mg/kg and rocuronium 0.5 mg/kg to produce neuromuscular blockade. Anesthesia was initially maintained with oxygen, nitrous oxide and sevoflurane. Mastoid surgery was complete...

The purpose of this investigation was to examine the effects of prolonged monaural amplification on the suprathreshold speech-recognition scores in the unaided ears of 46 persons with bilateral essentially symmetric and conductive hearing impairment and aided ears of 46 other persons with bilateral essentially symmetric and conductive hearing impairment. All subjects were less than 50 years of ...

INTRODUCTION AND OBJECTIVE Many designs of prostheses are available for middle ear surgery. In this study we propose a design for a new prosthesis, which optimises mechanical performance in the human middle ear and improves some deficiencies in the prostheses currently available. Our objective was to design and assess the theoretical acoustic-mechanical behaviour of this new total ossicular rep...

Many physicians confronting declining reimbursement from insurers have invested in ambulatory surgery centers, where they perform outpatient surgical and diagnostic procedures. An ownership stake entitles physicians to a share of the facility’s profits from self-referrals. This arrangement can create a potential conflict of interest between physicians’ financial incentives and patients’ clinica...

Background: Vaginal aplasia is a rare congenital anomaly with different surgical techniques suggested for vaginal reconstruction.McIndoe vaginoplasty is an easy one of these surgical methods with a low morbidity rate, but its long-term results need to be further investigated. Therefore, the female genital anatomy and sexual function was examined afte...
