“…This was consistent with other studies. Our findings supported previous research that concluded that laryngeal ultrasound has the same diagnostic ability as laryngoscopy in assessing vocal cord mobility [16,19]. On laryngoscope and ultrasound examination, seven of the thirty patients in the current study had confirmed vocal fold limited mobility.…”

“…Smoking is the leading cause of vocal fold cancer [15], and smokers account for 43% of cases with glottic suspicious mass in this study. The calcification of the thyroid cartilage hampered proper evaluation of the vocal folds [16], as the laryngeal space could not be seen clearly if the thyroid cartilage was calcified. Furthermore, a previous study found that complete anterior calcification of the thyroid cartilage created an acoustic shadow, making ultrasound evaluation of the larynx difficult, and that males had a higher rate of calcification than females [17].…”

Introduction:Since it was first suggested as a practical method of studying the larynx in 1960, ultrasonography has developed into a crucial and widely used diagnostic tool for conditions affecting the head and neck. Aim of the study:To evaluate the value of high-resolution ultrasonography as an easy, non-invasive method for diagnosing various vocal fold lesions as well as mobility disorders and correlate its findings with those of a laryngoscope examination. Subjects and Methods:We conducted this study at the Radiology Department in Fayoum University Hospital on thirty patients presenting with different vocal fold lesions for ultrasonographic examination of the head and neck between 2019 and 2021, which was approved by the local research ethical committee at the Faculty of Medicine at Fayoum University. Results:Vocal cord (VC) lesions without mobility affection were the most common sonographic finding (50%), especially VC polyp (20%), followed by (13.3%) for VC lesions with mobility affection, freely mobile both VC without any lesions during preoperative assessment, and freely mobile VC with mass lesion can't be assessed by ultrasound. Conclusion:Laryngeal ultrasonography is considered of great value in diagnosing different laryngeal lesions and can be used as a complementary procedure to laryngoscopy or an alternative in some cases. The limitation of laryngeal ultrasound is the calcification of thyroid cartilage with obscuration of distal structures, especially in elderly individuals.

Phonation is beyond doubt one of the highest functions of the human larynx. The vocal cords, also known as vocal cords, as the name suggests are infolding of mucosa aligned horizontally. The phonatory process, or voicing, occurs when air is expelled from the lungs through the glottis, creating a pressure drop across the larynx. When this drop becomes sufciently large, the vocal cords start to oscillate. The motion of the vocal cords during oscillation is mostly lateral, though there is also some superior component as well. However, there is almost no motion along the length of the vocal cords. The oscillation of the vocal cords serves to modulate the pressure and ow of the air through the larynx, and this modulated airow is the main component of the sound. The sound that the larynx produces is a harmonic series. In other words, it consists of a fundamental tone (called the fundamental frequency, the main acoustic cue for the percept pitch) accompanied by harmonic overtones, which are multiples of the (1) fundamental frequency .
