OBJECTIVES Optical coherence tomography (OCT) is a high-resolution optical imaging technique that produces cross-sectional images of living tissues using light in a manner similar to ultrasound. This prospective study evaluated the ability of OCT to identify the characteristics of laryngeal cancer and measure changes in the basement membrane, tissue microstructure, and the transition zone at th...

BACKGROUND In-office biopsy is an effective technique to diagnose the nature of pharyngolaryngeal lesions. METHODS We selected patients with pharyngolaryngeal lesions suspicious for malignancy. For in-office biopsy procedures, laryngeal cytology and direct laryngoscopy biopsy were performed, and diagnostic parameters and costs were estimated. RESULTS Eighty-eight patients were selected for ...

Patients with laryngeal lesions were observed and the lesions were recorded with an electronic videoendoscope system using the PENTAX EPM-3300 video processor and the PENTAX VNL-1330 endoscope portion. The electronic videoendoscope system differs from the conventional fiberoptic endoscope connected to a video camera in that a small monochrome charge-coupled device (CCD) chip is built in the tip...

Laryngeal carcinoma and laryngeal papilloma are the most commonly encountered tumorous lesions in the larynx. Herein, we report a case of the mass arising from the left vocal cord in a 49-year-old Japanese man. Endoscopic examination suggested that the mass is a tumor such as carcinoma and papilloma. Pathological examination showed that the specimen demonstrated actinomycosis in the left vocal ...

Granular cell tumors are benign subcutaneous or submucosal lesions of neurogenic origin. In this case study one patient was diagnosed and treated successfully with complete surgical resection of a laryngeal granular cell tumor that was originated from the left arytenoid region that very rare location. There is no evidence of recurrence 2 years after surgery. Granular cell tumors should be consi...

Primary cartilaginous lesions of the larynx are relatively uncommon. We present a case of bilaterally pseudocystic lesion of the thyroid cartilage that demonstrated progressive calcification. Pathologic analysis showed features suggesting a dystrophic lesion with no evidence of malignancy. We hypothesize that repetitive microtrauma related to muscular overuse probably led to inflammatory change...

About two thirds of laryngeal cancers originate at the vocal cords. Early-stage detection of malignant vocal fold alterations, including a discrimination of premalignant lesions, represents a major challenge in laryngology as precancerous vocal fold lesions and small carcinomas are difficult to distinguish by means of regular endoscopy only. We report a procedure to discriminate between maligna...

Objectives : Tuberculosis ,though a common condition in our country is still an enigma because of its varied modes of clinical presentation,characteristics and spread. Our objective is to stress the importance of an complete clinical examination and analysis of the symptomatology in arriving at the diagnosis of laryngeal lupus and provide an update on current knowledge and treatment of lupus vu...

A correlation between laryngo-pharyngeal reflux and laryngeal carcinoma is currently debated. Chronic inflammation is a mutagen factor confirmed in the cancerogenesis of various tumours. Aim of the present study was to evaluate, in an objective and consecutive way, with 24h multi-electrode pH-metry the presence of proximal and distal oesophageal reflux in patients presenting pre-cancerosis or s...

PURPOSE OF THE STUDY This study was undertaken to highlight the method, usefulness and postoperative morbidity of using a laryngeal mask airway (LMA) to ventilate patients with difficult airways undergoing laryngeal procedures. PROCEDURES Retrospective chart review where we identified patients deemed to have a difficult airway who underwent laryngeal and upper tracheal procedures, and were el...
