Objectives: We evaluated the diagnostic value of palpation, ultrasonography US , and computed tomography CT in detecting neck metastasis in head and neck cancers.Patients and Methods: The study included 35 patients 34 men, 1 woman; mean age 59 years; range 35 to 72 years with laryngeal carcinoma. İn addition to neck pal­ pation, 17 patients and 27 patients had neck examina- tions by US and CT, respectively. Histopathologic results of the neck specimens were compared with those obtained from palpation, US, and CT.Results: The accuracy of CT, US, and palpation in the evaluation of lymph nodes of the neck were 85%, 65%, and 80%, respectively. Ultrasonography was found to have the highest sensitivity 100% , but the least specificity 33% . The highest false positive and false negative results were obtained by US 42% and palpation 10% , respectively.Conclusion: Computed tomography proved superi- or to palpation and US in the evaluation of neck metastasis in patients with head and neck tumors.

Boyun metastazlarının gösterilmesinde palpasyon, ultrasonografi ve bilgisayarlı tomografinin karşılaştırılması

Öz

Amaç: Baş-boyun kanserlerinde boyun metastazlarının gösterilmesinde palpasyon, ultrasonografi USG ve bilgisayarlı tomografinin BT tanısal değerleri arafltırıldı.Hastalar ve Yöntemler: Çalıflmaya larenks kanserli 35 hasta alındı. Palpasyona ek olarak 17 olguda ve 27olguda boyunlar sırasıyla USG ve BT ile değerlendirildi. Boyun diseksiyonu uygulanan hastaların histopatoloji sonuçları USG, BT ve palpasyon bulgularıile karflılafltırıldı.Bulgular: Boyun lenf nodlarının değerlendirilmesinde doğruluk oranı BT ile %85, USG ile %65, palpasyon ile %80 bulundu. Ultrasonografi duyarlılığı enyüksek yöntem olmakla birlikte %100 , özgüllüğü endüflük %33 yöntem olarak belirlendi. En yüksek yalancı pozitiflik ve yalancı negatiflik oranları sırasıyla%42 ve %10 ile USG’de ve palpasyonda elde edildi.Sonuç: Bilgisayarlı tomografinin boyun lenf nodlarının değerlendirilmesinde USG ve palpasyondan daha güvenli bir tanı aracı olduğu görüldü
