Dynamic radiographic imaging following total laryngectomy

Cinepharyngoesophograms of the pharynx were obtained in 51 patients after total laryngectomy for squamous cell carcinoma. The radiological findings were correlated with operative reports and follow-up findings in 47 patients. Postoperative anatomic changes were well-demonstrated radiographically. A spectrum of radiographic findings were observed and included narrowing at the superior surgical closure site in 52% and pseudodiverticula in 47% of all patients. Cricopharyngeal prominence was observed in 15%, fistulae in 10%, and pharyngeal pouches in 6% of all cases. Increased retropharyngeal soft tissue thickness was not found to be indicative of tumor recurrence. We conclude that cineradiography is a useful method for demonstrating both functional and structural changes following laryngectomy for carcinoma.
