Preoperative ct scan evaluation for laryngeal carcinoma: Correlation with pathological findings

Abstract: The advent of newer generation high resolution computed tomography (CT) scanners has revolutionized diagnostic evaluation in head and neck cancer. Since the development of conservation surgical techniques for the larynx, a precise preoperative evaluation of the extent of laryngeal involvement by carcinoma has been of prime importance. No single diagnostic study now yields more information regarding the anatomic extent of tumor than high resolution CT scanning. This study was designed to evaluate the reliabilit… Show more

“…Tumor on both sides or the extralaryngeal side of the cartilage, which is usually present in advanced cases, is generally accepted as a specific radiologic sign of cartilage invasion and has a reported specificity of 95%. 13 Other radiologic signs used to predict early cartilage invasion include cartilage sclerosis, intramedullary cartilaginous mass, cartilaginous explosion, cartilage lysis, and cartilage bowing. [14][15][16][17] Sclerotic changes in the laryngeal cartilage as a result of tumoral involvement are controversial.…”

“…Yapılan üç çalışmada preepiglottik bölge için BT'nin doğruluk oranları sırasıyla %26.6, %72, %85.1 iken çalışmamızda ise %75 bulunmuş-tur (5,6,14). Bu bölgedeki anatomik varyasyonların geniş olması ve basit bir ödemin bile kitle imajı vermesi bu alandaki yanlış pozitif sayıyı arttırmaktadır (15).…”

“…Os carcinomas que se originam na região aritenóide ou interaritenóide apresentam tendência a estender-se de forma submucosa (12) . A TC pode não ser confiável na existência de reações actínicas intensas nos diversos níveis analisados (18) . Nos casos do presente estudo existiu concordância interobservadores em 21 pacientes, representando concordância ótima (índice kappa = 0,86).…”

“…A TC demonstra a extensão tumoral longitudinal superior e inferior de forma mais precisa que os métodos radiológi-cos convencionais (18,24) . A obtenção de múltiplos níveis para análise através de cortes axiais facilita a delimitação da extensão tumoral superior (25) .…”
