OBJECTIVE To analyze the outcome of transnasal endoscopic repair of choanal atresia (CA) in children without prolonged nasal stenting after surgery. DESIGN Retrospective study. SETTING Academic tertiary care children's hospital. PATIENTS Forty children aged 3 days to 15 years (mean age, 41 months) who presented with unilateral (n = 26) or bilateral (n = 14) CA and underwent surgery betwee...
Biliary stent placement is an adjunct for complex biliary intervention. Patients with benign biliary strictures or aversion to external drainage may benefit from placement of retrievable biliary stents. This report describes a patient with a working diagnosis of benign biliary stricture who underwent interventional radiology-operated endoscopy-guided transnasal placement of a fully covered retr...
The more progress that has been made in endoscopy, the more superficial cancers have been found in the head and neck regions [1–4]. There are, however, some areas that are difficult to observe on transoral esophagogastroduodenoscopy (EGD). In particular, only a tangential view of the radix linguae is obtained with transoral EGD. In this report, we present the procedure for an intraoropharyngeal...
PURPOSE The purpose of our study was to introduce an ultrafast MR imaging technique of the pharynx as a diagnostic tool for viewing the mechanism of obstruction in patients with obstructive sleep apnea. METHODS Six healthy volunteers and 16 patients with obstructive sleep apnea were examined on a 1.5-T whole-body imager using a circular polarized head coil. Ultrafast two-dimensional fast low-...
BACKGROUND Transnasal cannulation of the natural ostium in patients with an intact uncinate process is complicated by the lack of direct visualization of the ostium. Accuracy of transnasal dilation of the maxillary ostium was evaluated for a malleable-tipped balloon device that was bent to specific angles for avoiding the fontanelle during cannulation. METHODS Transnasal cannulation and dila...
INTRODUCTION In recent years, the surgical management of angiofibroma has been greatly influenced by the use of endoscopic techniques. However, large tumors that extend into difficult anatomic sites present major challenges for management by either endoscopy or an open-surgery approach which needs new technique for the complete en block resection. MATERIALS AND METHODS In a prospective observ...
Aims. In order to determine the indications of transoral surgery for a tumor located at the pharyngoesophageal junction, the trumpet maneuver with transnasal endoscopy was used. Its efficacy is reported here. Material and Methods. An 88-year-old woman complaining of dysphagia, diagnosed with cervical esophageal cancer, and hoping to preserve her voice and swallowing function was admitted to our...
