Compare two surgical interventions for otitis media with effusion in young children

To prospectively evaluate the effect of tympanostomy tubes combined with adenoidectomy and tube insertion on treatment for otitis media with effusion in young children, and to analyze the related factors of prognosis and recurrence of the disease.

The clinical and follow-up data of 184 children with otitis media with effusion who were treated in the department of Otolaryngology, Head and Neck Surgery, Beijing Children's Hospital, Capital Medical University from September 2013 to January 2015, were reviewed systematically. According to different surgical methods, they were randomly divided into the observation group in which patients were treated with tube insertion combined with adenoidectomy, and control group in which the rest underwent simple tube insertion. The curative effect, changes of air conduction hearing threshold before and after surgery, the healing time of tympanic membrane and recurrence of middle ear effusion were compared between the two groups. Influencing factors of recurrence of otitis media with effusion were analyzed, and the effect of healing time on tympanic membrane after tube removal was observed.

The total effective rate of treatment in the observation group was higher than that in the control group (91.84% vs 80.23%, P < 0.05), and the air conduction hearing thresholds in two groups were decreased significantly at 3 months and 6 months after surgery, respectively (P < 0.05). The total effective rate of children under 4 years old in the observation group was also higher than that in the control group. The duration of middle ear effusion and the recurrence rate in the observation group were shorter/lower than those in the control group (P < 0.05). Analysis showed that recurrent respiratory tract infection before surgery and retention time of ventilating tube shorter than 12 months were risk factors for recurrence of otitis media with effusion, while adenoidectomy was a protective factor. Besides, the tympanic membrane healing time of the tympanic membrane tube for 1 years was shorter than that of the tympanic membrane tube for more than one year (P < 0.05). The persisted perforation rate is 3.57% in less 12 months of tube, as opposed to it was 12% in more 12 months of tube (P < 0.05).

Tube insertion combined with adenoidectomy is more effective than tympanostomy tubes in the treatment of young children with OME, and the same results were found for children under four years of age. It can significantly shorten the duration of middle ear effusion and reduce the recurrence rate after surgery. For 3-6 year-old children, the upper respiratory tract infection and short ventilation tube indwelling time increase the possibility of OME recurrence, it is recommended that the ventilation tube should be retained for at least 12 months.
