BACKGROUND/AIM: A pharyngeal fistula is the most common complication of total laryngectomy; thus, accurate diagnosis and treatment are important. Diagnosis is usually made by the finding of leakage of the contrast agent outside the pharynx during swallowing contrast examination. Herein, we encountered a case in which fine leaks not detected on contrast examination during swallowing were visualized and diagnosed by computed tomography (CT) imaging with oral contrast media with the patient in a prone position. CASE REPORT: During imaging in a prone position, the contrast agent entered the sutures on the cephalocaudal and ventral sides of the surgical site, which were particularly prone to leaks due to gravity, and it was possible to diagnose minute leaks. When there is a high risk of postoperative pharyngeal fistula, such as in reconstructive cases with a pedunculated flap or with overlapping risk factors such as preoperative irradiation, CT imaging with contrast medium in a prone position is considered useful when swallowing contrast examination does not provide a clear diagnosis. However, suture failure is possible, and this should be evaluated. CONCLUSION: This case suggests that routine prone CT may lead to the early detection of postoperative pharyngeal fistula in high-risk cases. Further accumulation of cases is required to confirm our findings.
