title: [Endoscopic laser surgery in combined nasopharyngeal and middle ear pathology in children with conductive hypoacusis].
abstract: Endoscopic laser surgery on lymphoid structures of the nasopharynx near the pharyngeal opening of the auditory tube was made with Lazon-10P laser in 67 children aged 3 to 14 years with documented exudative otitis media (EOM). All the children had conductive hypoacusis. Children who had tympanogram of type B and in whom otoscopy detected exudate behind the tympanic membrane were subjected to one-stage laser tympanostomy in the anteroinferior quadrant of the tympanic membrane followed by transtympanic drug introduction into the tympanic cavity. Tympanostoma closed spontaneously 3 weeks later. Normal hearing recovered in all the children. Diagnostic endoscopy of the nasopharynx can reveal causes underlying dysfunction of the auditory tube. The results demonstrate high efficacy of the methods allowing elimination of mechanical occlusion of the auditory tube in the region of its pharyngeal opening with one-stage intervention on the middle ear.
