PRIMARY outcome

Timeframe: Procedural

Population: One subject was missing data on intraprocedural adverse events and is excluded from this analysis.

TTDS success will be confirmed by the successful delivery of a tube to the tympanic membrane.

Percentage of Ears Treated Successfully With the TTDS in the Absence of Acute Intraprocedural Adverse Events.
94.6 percentage of ears
Interval 81.8 to 99.3

SECONDARY outcome

Timeframe: 12 months

Population: Over the course of 12 months, a total of 17 subjects (25 ears) were assessed at varying follow-up time points as having had tubes extruded. Ears analyzed included those for which a tube was observed to extrude at any follow-up visit and ears that completed the 12 month visit.

SECONDARY outcome

Timeframe: 30 days

Population: One subject (one ear) was lost to follow-up immediately following the procedure.

This measure assesses the patency (openness or lack of obstruction) of unextruded tubes.

SECONDARY outcome

Timeframe: 3 months

Population: Two subjects were lost to follow-up after the 30 day visit and one subject missed the 3 month visit. One subject was lost to follow-up immediately following the procedure. Thus, only 28 ears of 21 participants had unextruded tubes for assessment of tube patency.

This measure assesses the patency (openness or lack of obstruction) of unextruded tubes.

Timeframe: 6 months

Population: Two subjects lost to follow-up after 3 month visit. Two subjects missed 6 month visit. Two subjects lost to follow-up after 30 day visit. One subject lost to follow-up immediately following procedure. Thus, only 13 ears (= 9 participants) of 18 participants returning at 6 months had unextruded tubes for assessment of patency.

This measure assesses the patency (openness or lack of obstruction) of unextruded tubes.

Thus, only 3 ears (= 3 participants) of 16 participants returning at 9 mos had unextruded tubes for assessment of patency.

This measure assesses the patency (openness or lack of obstruction) of unextruded tubes.
