INTRODUCTION Surgical organ preservation approaches constitute important treatment options for laryngeal cancer. Supracricoid partial laryngectomies (SCPLs) are open surgical techniques designed to resect selected advanced endolaryngeal tumors without major invasion of the infraglottis, involvement of the posterior commissure, or fixation of the cricoarytenoid (CA) joint. One of the key oncolog...
BACKGROUND Laryngeal squamous cell carcinoma (SCC) accounts for 1.9% of cancers worldwide. Most of these are diagnosed in the early stages (T1-T2, and N0). For these, a larynx preserving/conserving option is preferable. Beyond transoral laser microsurgery (TLM), open partial horizontal laryngectomy is a function-sparing surgical technique used to treat laryngeal SCC. METHODS We retrospectivel...
Background: Phonomicrosurgery is a challenging and evolving field. One of the key techniques used for this is micro-flap technique used along with cold micro instruments. Objective: To convey the role of Microflap technique in phonosurgery and the role of basic microlaryngeal instrumnets in such surgery when sophisticated phonomicrosurgical instruments are not available. Methods: This is a retr...
Objective: To evaluate the clinicopathologic findings and treatment outcome in laryngectomized patients with laryngeal cancer and hypopharyngeal cancer. Materials and Methods: The authors retrospectively reviewed the medical records of 212 patients who had been newly diagnosed and treated with laryngectomy between January 2000 and December 2010. The age, gender, clinical manifestations, associa...
The principles of open versus laser microsurgical approaches for partial resections of the larynx are described, oncologic as well as functional results discussed and corresponding outcomes following primary radiotherapy are opposed. Over the last decade, the endoscopic partial resection of the larynx has developed to an accepted approach in the treatment of early glottic and supraglottic carci...
INTRODUCTION Clinical staging is the most important time in management of glottic cancer in early stage (I-II). We have conducted a prospective study to evaluate if magnetic resonance imaging (MRI) is more accurate than computed tomography (CT) about tumoral extension, to exactly choose the most appropriate surgical approach, from organ preservation surgery to demolitive surgery. MATERIALS and ...
the space now known as complete erdos space ec was introduced by paul erdos in 1940 as the closed subspace of the hilbert space ?2 consisting of all vectors such that every coordinate is in the convergent sequence {0} ? { 1 n : n ? n}. in a solution to a problem posed by lex g. oversteegen we present simple and useful topological characterizations of ec. as an application we determine the ...
in chapter 1, charactrizations of fragmentability, which are obtained by namioka (37), ribarska (45) and kenderov-moors (32), are given. also the connection between fragmentability and its variants and other topics in banach spaces such as analytic space, the radone-nikodym property, differentiability of convex functions, kadec renorming are discussed. in chapter 2, we use game characterization...
OBJECTIVES The aim of this study was to determine the role of preepiglottic space (PES) invasion in lymph node metastasis and prognosis in patients undergoing supracricoid partial laryngectomy (SCPL) with cricohyoidopexy (CHP). METHODS A retrospective review of 42 previously untreated patients with squamous cell carcinoma of the larynx that underwent surgery was performed. The mean age of the...
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
