Abstract: Objective To discuss the clinical manifestations and difficulties in the diagnosis and treatment of hypopharyngeal fibrovascular polyps, to summarise experience, to reduce misdiagnosis and missed diagnosis, and to select surgical methods accurately. Methods The literature was reviewed and the diagnosis and management of a patient with a hypopharyngeal fibrovascular polyp was summarised. The clinical manifestations, the course of the disease, the results of accessory examinations and the difficulties of treatment were analysed. Results Hypopharyngeal fibrovascular polyps can migrate in the larynx and esophagus, and the surface is covered with normal epithelial tissue, which is prone to misdiagnosis and missed diagnosis in the clinic. A comprehensive diagnosis should be made on the basis of clinical symptoms supported by endoscopy, imaging and other investigations. Anesthesia is safe when polyps are located in the esophagus, and endoscopic surgical resection is the preferred method of treatment. Conclusion Hypopharyngeal fibrovascular polyps are rare and prone to misdiagnosis and missed diagnosis. It is very important to perform a complete preoperative evaluation, establish a clear diagnosis, and choose an appropriate surgical approach based on the location, width, size and composition of the root base.
