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 ...

Solitary median maxillary central incisor (SMMCI) coexists in 34%-65% of patients initially diagnosed with congenital nasal pyriform aperture stenosis. SMMCI, a genetic syndrome, warrants consideration for further screening because of its high prevalence of other diagnostic possibilities-specifically central defects, like nasal obstruction and hypothalamo-pituitary axis abnormalities. We report...

Congenital nasal pyriform aperture stenosis (CNPAS) is a very rare condition of the newborn, in which the nasal pyriform aperture is narrowed by bony overgrowth of the nasal process of the maxilla (Figure 1). As the narrowest point of the nasal airway, a small change in its diameter may significantly increase nasal airway resistance. As infants are obligate nose breathers for the first three mo...

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...

PURPOSE There are marked differences in facial skeletal characteristics between Asian and Caucasian. However, ethnic differences in age-related facial skeletal changes have not yet been fully established. The aims of this study were to evaluate age-related changes in Asian midfacial skeletons and to explore ethnic differences in facial skeletal structures with aging between Caucasian and Asian....

The definition of these sites is shown in Table 13.1. The larynx projects into the hypopharynx from the front so that grooves, known as the pyriform fossae, are formed on either side. These are shallow above and are separated from the valleculae by the pharyngoepiglottic folds. Lower down, the pyriform fossae become deeper. The upper shallow part of the pyriform fossa is bounded laterally by th...

Amdur RJ, Mendenhall WM, Stringer SP, et al. Organ preservation with radiotherapy for T1-T2 carcinoma of the pyriform sinus. Head Neck. 2001;23:353-362. 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...

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...

INTRODUCTION Congenital nasal pyriform aperture stenosis and solitary median maxillary central incisor are uncommon anomalies and are associated with further malformations. Solitary median maxillary central incisor itself has initially no impact on a child's health, but congenital nasal pyriform aperture stenosis is a potentially life-threatening condition. CASE PRESENTATION A Caucasian baby ...
