Myringotomy with trans-tympanic T-tube (TTT) placement is the most common surgical procedure performed in children. Finding a technique that provides longer aeration periods, lower complications rates, and less need for subsequent interventions will help the healthcare system from preventable events.

To compare the efficiency and complications rates of the traditional TTT to those of the novel postero-superior tubes in a grooved bone (TGB) for long-term middle ear ventilation in children suffering from recurrent acute otitis media (RAOM), or chronic otitis media with effusion (COME).

A total of 200 pretreated ears (96 by TGB and 104 by TTT), were examined after at least 3 years. Data concerning tube condition, and ear outcomes were collected. Pre- and post-operative audiograms were also performed.

TGB remained in place for longer periods, and it resulted in significantly lower rates of persistent tympanic membrane (TM) perforation (0% vs. 30.8%), TM retraction (14.6% vs. 32.7%), myringo sclerosis (12.5% vs. 38.4%), otorrhea (29.2% vs. 52.9%), and need for topical antibiotics (31.3% vs. 51%). It has also resulted in more significant reduction in the air-bone gap on audiograms.

Conclusions and significance: TGB could be an effective and safe option for middle ear ventilation following COME or RAOM in children.
