The incidence of arytenoid dislocation in abdominal surgery is relatively high, the cause is unknown, and it has not received sufficient attention. To identify the risk factors of arytenoid dislocation after abdominal surgery, and to establish a clinical prediction model based on relevant clinicopathological characteristics. We retrospectively collected the clinical data of 50 patients with arytenoid dislocation (AD) and 200 patients without AD after abdominal surgery with general anesthetic tracheal intubation in our Hospital from January 2013 to December 2019.

Objective: Using dynamic computed tomography (CT) to explore the structural characteristics of the larynx in patients with arytenoid dislocation and compare the impact of the dislocation course on the structural changes of the larynx.

Methods: Twenty-three patients with arytenoid dislocation and 10 healthy subjects were selected as the dislocation group and the normal group, respectively. The 23 patients with arytenoid dislocation were divided into groups with dislocation duration less than 3 months (group A) and dislocation duration more than 3 months (group B).

Department of Otolaryngology-Head and Neck Surgery, School of Medicine, Jichi Medical University, Shimotsuke, Tochigi, Japan.

Objective: Ultrasound provides real-time anatomical information and motion. We used ultrasound to image the cricoarytenoid joint and its rotating, rocking, and gliding movements.

Methods: Between March and October 2023, 20 patients (10 males and 10 females) who visited our hospital underwent laryngeal ultrasonography.

Objective: To explore the efficacy of voice therapy combined with closed reduction under local anesthesia upon arytenoid dislocation (AD) and to provide new reference for the clinical treatment of AD.

Methods: Fifty-eight patients diagnosed with unilateral AD were enrolled in the study, which were divided into the closed reduction group under local anesthesia alone (25 cases) and the closed reduction group under local anesthesia combined with voice therapy (33 cases) according to the treatment regimen. The vocal cord movements of the two groups were observed under laryngoscopy before and after treatment.
