Arterial Anatomy in the Normal Larynx and in Laryngeal Carcinoma

For a correct selection of patients with laryngeal carcinoma for surgery, especially when partial surgery is contemplated, it is important to ascertain the extent of deep tumour invasion. The usual radiologic methods and microlaryngoscopy have shortcomings in this respect. Angiography of normal specimens demonstrated that the arterial anatomy is fairly constant and characteristic. Specimens from carcinoma patients displayed vascular abnormalities related to deep invasion, as demonstrated at microscopic examination.
