A young child’s larynx was formerly believed to be narrowest at the cricoid level, circular in section, and funnel shaped. This supported routine use of uncuffed endotracheal tubes children despite benefits cuffed tubes, such as lower risk for air leakage aspiration. In late 1990s, evidence supporting pediatric emerged largely from anesthesiology studies, while some technical flaws remained a...

PURPOSE To assess the effect of cricoid pressure on the positioning of and ventilation through the laryngeal mask airway (LMA). METHODS In a double-blind, randomized design, the LMA was inserted with (CP[+] group, n = 20) or without double-handed cricoid pressure (CP[-] group, n = 20). Ventilation through the LMA was assessed by measuring expiratory tidal volume and judged as adequate when a ...

RATIONALE Laryngeal cancer is aggressive tumor that arises from the tissues of the larynx. Although any bone can be affected, involvement of cricoid cartilage was reported very rarely, and there has been no report of 18F-sodium fluoride positron emission tomography-computed tomography (F-NaF PET-CT) and 3D PET-CT for the evaluation of cricoid cartilage invasion. PATIENT CONCERNS A 54-year-old...

PURPOSE To retrospectively assess the prognostic meaning of tumor characteristics depicted on pretreatment magnetic resonance (MR) images for local outcome in supraglottic squamous cell carcinoma treated with definitive radiation therapy. MATERIALS AND METHODS Pretreatment MR images acquired in 84 patients with supraglottic carcinoma treated with curative radiation therapy were reviewed for t...

Endotracheal tube (ETT) should be placed at the optimal level to avoid single lung ventilation or accidental extubation. This study was performed to estimate the mid-tracheal level by using surface anatomical landmarks in adult patients.Neck computed tomography images of 329 adult patients between the ages of 16 and 79 years were reviewed. In the midline sagittal plane, the levels corresponding...

Solitary plasmacytoma (SP) is an extremely rare form of hematologic malignancy that can be classified as solitary bone plasmacytoma or solitary extramedullary plasmacytoma. Here, we report a patient who presented with progressive shortness of breath and foreign body sensation in his throat. Fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) demonstrated an abno...

Extramedullary plasmacytoma (EMP) is an uncommon tumor of the plasma cells, and EMP of the cricoid cartilage is extremely rare The present study reports the rare case of a 43-year-old male complaining of hoarseness and dyspnea for over a year. Computed tomography imaging of the neck revealed an occupying lesion in the cricoid cartilage, and a diagnosis of EMP was subsequently confirmed by histo...

Right Internal Jugular Vein (RIJV) catheterization may be collapsed by the advancement of the needle and the pressure from ultrasonic probe, and the sutures are needed to fix the catheters after RIJV catheterization. This study aimed to develop a Suture-Traction Method (STM) to facilitate RIJV catheterization. 70 anesthetized patients underwent RIJV catheterization in Left-Lateral Position (LLP...
