OBJECTIVES/HYPOTHESIS The aim of this study was to analyze the prevalence and distribution of histologic cervical lymph node metastases in medial wall pyriform sinus squamous cell carcinoma (SCC). STUDY DESIGN Retrospective study of medical records. METHODS We reviewed the medical records of 68 medial wall pyriform sinus SCC patients who underwent bilateral neck dissection for primary treat...

Pyriform sinus fistula is important despite its rarity, as it can induce a recurrent neck abscess. Most of the reported cases occur in children and the majority affect only the left side. We report a patient with a pyriform sinus fistula of the right neck in an adult, which was successfully treated by surgery. The aetiology of this entity is also discussed herein.

Background/Aims We attempted to examine the relationship between abnormal findings on high-resolution manometry (HRM) and videofluoroscopic swallowing study (VFSS) of the pharynx and upper esophageal sphincter (UES), and to identify the risk factors for aspiration. Methods We performed VFSS and HRM on the same day in 36 ischemic stroke patients (mean age, 67.5 years) with dysphagia. Pressure ...

The authors reported on 101 patients with T1-T2 carcinoma of the pyriform sinus treated at the University of Florida with radiation therapy with or without a planned neck dissection for organ preservation. Radiation therapy alone or combined wi...

BACKGROUND High-risk human papillomavirus (HPV) is an oncogenic virus that causes oropharyngeal cancers, and it has a favorable outcome after the treatment. Unlike in oropharyngeal cancer, the prevalence and role of high-risk HPV in the etiology of hypopharyngeal squamous cell carcinoma (HPSCC) is uncertain. OBJECTIVE The aim of the present study was to evaluate the effect and prognostic sign...

BACKGROUND AND PURPOSE Acute suppurative neck infections associated with branchial fistulas are frequently recurrent. In this study, we describe the imaging findings of acute suppurative infection of the neck caused by a third or fourth branchial fistula (pyriform sinus fistula). METHODS Imaging findings were reviewed in 17 patients (11 female and six male patients, 2 to 49 years old) with ne...

A 77-year-old man was admitted for abdominal pain. He had no anemia or abnormal physical findings. We diagnosed the patient with chololithic pancreatitis, and performed endoscopic retrograde cholangiopancreatography. We began to insert a side-viewing duodenoscope, but had difficulty passing it through the left pyriform sinus. When we switched to a forward-viewing duodenoscope, we found that mem...
