ABSTRACT
Objective:To analyze the factors influencing the difference in location of cricothyroid membrane between traditional surface palpation and ultrasonic biplane.Methods:One hundred and seven subjects of both sexes, aged 18 yr, underwent neck ultrasound examination in our hospital from August 2021 to December 2021, were selected.The structure of cervical airway was observed by ultrasound.The subjects in whom the structure of cricothyroid membrane was clearly shown were selected.The middle point of cricothyroid membrane was located by otorhinolaryngologist using surface palpation method and by ultrasonic doctor using ultrasonic biplane method.The distance between two positioning points was measured by a ruler.The subjects were divided into accurate group (distance between two points≤3 mm) and difference group (distance between two points>3 mm). The distance between cricoid cartilage and thyroid cartilage (spacing of cricoid cartilage and thyroid cartilage) and distance between the midpoint of cricothyroid membrane and skin (spacing of cricothyroid membrane and skin) were measured by ultrasound.The neck length and the maximum submaxillary distance in head up were measured by a ruler.The factors influencing the difference in location between the two methods were analyzed by multivariate logistic regression.Results:One hundred and four subjects with clear cricoid cartilage and cricothyroid membrane under ultrasound were selected.There were significant differences in the ratio of gender, body mass index (BMI), cricothyroid membrane-skin distance, neck length, and maximum submandibular distance between the two groups ( P<0.05). Multivariate logistic analysis showed that female ( OR=9.091, P<0.001), BMI ( OR=11.214, P=0.001) and increased cricothyroid membrane-skin distance ( OR=5.649, P=0.015) were the factors influencing the difference in location between the two cricothyroid membrane localization methods. Conclusions:Female, obesity (BMI>28.0 kg/m 2) and increased distance between cricothyroid membrane and skin are the factors affecting the difference in location of cricothyroid membrane between ultrasonic biplane method and surface palpation method, and bedside ultrasound is recommended for location in those with the factors mentioned above.
ABSTRACT
OBJECTIVE@#To Study the personality characteristics in patients with sudden deafness.@*METHOD@#Thirty-eight sudden deafness patients and 45 healthy volunteers were assessed by Eysenck personality questionnaire (EPQ).@*RESULT@#The standard scores of P, E, N dimensions of patients with sudden deafness were greater than healthy volunteers. The standard score in L dimensions of patients with sudden deafness was less than healthy volunteers. The difference of the standard score of P dimension revealed statistical significance (P 0.05).@*CONCLUSION@#Sudden deafness patients have emotional instability and psychoticism personality characteristics.

A male patient, 55 years old, suffered from intermittent sound,voice depression and shortness of breath for one year,and from dysphagia for 3-4 months. Through fiber laryngoscopy,we could see tumor in the left posterior aryepiglottic fold. The tumor's surface was smooth. A portion of the tumor protruded to the laryngeal cavity and the aryepiglottic fold external,it also covered most of the glottis. Bilateral vocal cord were smooth and had good mobility. Throat CT demonstrated an irregular soft tissue mass on the left side of the aryepiglottic fold in supraglottic area with obscure normal boundary from adjacent structure. The left side of pyriform sinus became shallow without obvious bone destruction. The pathological report showed pleomorphic adenoma. The diagnosis was laryngeal pleomorphic adenoma.
