The application of thin rhinolarynx electronic videoendoscope in the infants with laryngopharyngeal disease

Abstract

Objective To investigate the value of thin rhinolarynx electronic videoendoscope in the diagnosis of laryngopharyngeal disease of infants. Methods Pentax-1130 thin rhinolarynx electronic videoendoscope was used to examine 121 infants (included newborn) under 3 years with laryngeal stridor accompanied with inspiratory dyspnea or hoarse voice. Results Of 121 children,66 cases were laryngomalacia (54. 5%), 29 cases were laryngopharyngeal congenital cyst (24. 0% ), 7 cases were laryngeal papilloma (5. 8% ) ,6 cases were vocal cord paralysis(5. 0% ) ,5 cases were foreign body in glottis(4. 1% ) ,3 cases were retropharyngeal abscess(2. 5% ) ,retropharyngeal mass,fibroma of larynx,glottic laryngeal web,foreign body in hypopharynx and tracheal stenosis were each 1 case(0. 8% ). Conclusion Among 121 cases with laryngeal stridor accompanied with inspiratory dyspnea except laryngomalacia, nearly half of the cases were found structural disease by using rhinolarynx electronic videoendoscope. Thin rhinolarynx electronic videoendoscope plays predominant role in the diagnosis of laryngopharyngeal disease happened in the infant and newborn. It is easy to follow-up, without requirment of subscription and conscious-sedation. The image is clear and reliabale. The examination can be performed under general breathing, with less complication and could be applicable extensively.
