Abstract:
OBJECTIVE To explore the value of ultrasonography in the diagnosis of congenital laryngeal web.METHODS A total of 10 pediatric patients with congenital laryngeal web who were admitted to Beijing Tongren Hospital,Capital Medical University from April 2013 to December 2024 were collected.Among them,there were 5 males and 5 females,with ages ranging from 1 month and 16 days to 16 years old after birth,and a median age of 1 year and 11 months.Clinical manifestations included laryngeal stridor,hoarseness,or weak crying after birth.All patients underwent laryngoscopy and laryngeal ultrasonography.The diagnosis was made by combining ultrasound and laryngoscopy examinations.RESULTS It was confirmed by laryngoscopy and operation:The final diagnosis was glottic laryngeal web in 7 cases and combined glottic-subglottic type in 3 cases.In the transverse ultrasound view,glottic laryngeal web appears as a triangular hypoechoic area at the anterior commissure of the glottis level,with its posterior edge presenting as an arc shape,and the interface with air is hyperechoic.In the sagittal ultrasound view,certain web-like structures appear as a strip of hypoechoic area in the midline behind the thyroid cartilage.The thickness can be measured to determine whether it extends from the glottis to the subglottis.For infans,and for subglottic laryngeal web,it is difficult to show the lesion by ultrasound.CONCLUSION Ultrasonography is helpful in the diagnosis of laryngeal web and can display the thickness of the web in the sagittal plane,providing three-dimensional information for preoperative planning.
