OBJECTIVES Because early detection and preoperative assessment of laryngeal cancer and its precursor lesions are essential for curative and function-preserving surgical treatment, autofluorescence endoscopy has been developed to gain more information about the biologic character of these lesions. The aim of the present study is to investigate a high,(More)
The objective of the study was to assess the epithelial thickness in different lesions of the vocal folds in order to gain more information about its influence on endoscopic imaging. Retrospective study including 161 patients undergoing surgery for a total of 206 benign and malignant lesions of the vocal folds. Laryngoscopy and autofluorescence endoscopy(More)
In the last decades new endoscopic tools have been developed to improve the diagnostic work-up of vocal fold lesions in addition to normal laryngoscopy, i.e., contact endoscopy, autofluorescence, narrow band imaging and others. Better contrasted and high definition images offer more details of the epithelial and superficial vascular structure of the vocal(More)
Direct autofluorescence endoscopy of the larynx has proven to facilitate the detection and delineation of precancerous lesions, carcinoma in situ and cancer. The aim of the present study was to evaluate the diagnostic potential and limitations of this imaging technique applied during indirect laryngoscopy. In a prospective study, 116 patients with suspected(More)
Indirect fluorescence endoscopy of the larynx has proven to facilitate the detection and delineation of precancerous and cancerous lesion. The different methods are easy to handle and can be performed on an outpatient basis. Early diagnosis of laryngeal cancer and its precursor lesions is simplified. The aim of the present study is to compare indirect(More)
BACKGROUND Narrow band imaging (NBI) is a new imaging technique for the depiction of tumor-specific neoangiogenesis. The purpose of the present study was to assess the value of NBI in the early diagnosis of laryngeal cancer. METHODS This prospective study includes 205 consecutive patients with a laryngeal lesion scheduled for microlaryngoscopy. NBI was(More)
BACKGROUND Fluorescence endoscopy is used for the early detection and delineation of laryngeal cancer and its precursor lesions. No systematic review of these promising imaging techniques has yet been performed. METHODS A systematic review of the published literature and meta-analysis of data extracted from 16 included studies were performed. A total of(More)
BACKGROUND In order to improve preoperative diagnostic work-up in treatment of patients with laryngeal cancer and its precursor lesions additional endoscopical imaging techniques have been developed: 1. Autofluorescence endoscopy; 2. Contact endoscopy; 3. Endoscopic high-frequency ultrasound. These imaging techniques are used during microlaryngoscopy to get(More)
The term phonosurgery (PS) refers to any operation designed primarily for the improvement or restoration of voice. It is defined by the intended operative goal, which pertains to quality of life rather than its preservation, and informed consent needs to account for this emphasis. Since the aim is improvement or maintenance of vocal function, it is(More)
