2023年11月3日 · The epiglottis is a cartilaginous flap that extends in front and above the laryngeal inlet, or more specifically the rima glottidis (glottis). The function of the epiglottis is to close the laryngeal inlet during swallowing and so to prevent the …

2024年10月5日 · If a lateral neck x-ray is performed, the criterion of 7-mm thickness (average standard epiglottic thickness is 3 to 5 mm) provides 100% sensitivity and specificity for acute adult epiglottitis. A chest x-ray is helpful to rule out pneumonia; however, most otolaryngologists prefer neck CT if the patient is stable.

Epiglottic edema will often preclude the use of a laryngeal mask airway. In severe epiglottitis, orotracheal intubation may simply be impossible. ⚠️ Don't perform traditional RSI (rapid sequence intubation) in epiglottitis – this is likely to provoke …

Acute epiglottitis is a life-threatening disorder with serious implications to the anesthesiologist because of the potential for laryngospasm and irrevocable loss of the airway. Acute epiglottitis can occur at any age.

2024年10月30日 · Epiglottitis is a condition in which swelling deep inside your throat blocks your airway, making it hard or impossible to breathe. It's a medical emergency, and if not treated quickly, you...

会厌 （epiglottis、會厭軟骨）是覆盖了一层黏膜组织的 软骨，和 舌 根部相连，位于舌头及 舌骨 稍微偏上的后方。 人们通常容易将 会厌 或者 扁桃体 这两个词误认为是 小舌 [2]。 会厌形状如同一带柄的树叶，柄部在下。 其扼守着 声门 的入口，而声门指的是喉咙中声带之间的位置。 在平常 呼吸 的时候，会厌会朝上打开（柄在下，叶在上），露出声门，此时其下半部是咽的一部分。 但在 吞咽 的时候，则因为 舌骨 的提升而导致会厌下降并盖住 喉咙，此时其上半部为咽的一部分。 …

The results of this study showed that a pre-existing epiglottic cyst might be associated with a suppurative infection of the supraglottis. Infected epiglottic cysts increased the risk for airway obstruction and recurrence of acute epiglottitis.

Lateral neck radiography is often used as a screening tool in emergency departments for suspected acute epiglottitis. The qualitative radiographic signs have been mainly used. The aim of this study was to evaluate the accuracy of objective radiographic parameters to aid diagnosis of acute epiglottitis.

On cervical ultrasonography (transverse view), the epiglottis was swollen with anterior‐posterior diameter of 3.5 and 3.8 mm at right and left edges, respectively. Laryngeal endoscopy showed marked swelling of the epiglottis, and acute epiglottitis was diagnosed. Keywords: acute epiglottitis, point‐of‐care ultrasound, throat pain.

Muffled voice (P < .013), respiratory distress (P < .001), and pre-existence of epiglottic cyst (P < .001) are symptoms and signs connected with abscess formation. A total of 120 patients were treated conservatively.
