Brief summary

Elevation of the soft palate (the soft part of the roof of the mouth) during swallowing helps the Eustachian tube to open and keep the ear healthy. (The Eustachian tube is the normal tube running from the middle ear to the back of the nose and throat). When the soft palate does not move enough (due to a history of cleft palate or for unknown reasons), this can lead to speech problems. Also, because the Eustachian tube is not opening enough, fluid can accumulate in the middle ear, which requires treatment with ear tubes. The goal of this research study is to determine if soft palate exercises will help improve the ability of the soft palate to close the area between the throat and nose, like it is supposed to during speech and swallowing, and if this improves Eustachian tube opening.

Detailed description

This trial will look at the feasibility and effect of device-assisted soft palate exercises for the treatment of chronic Eustachian tube (ET) dysfunction (ETD) in older children still experiencing middle-ear disease. Children with or without cleft palate (CP) with ventilation tubes (VTs) will be evaluated for the function of the soft palate and the ET. Subjects with active muscular ETD and inadequate soft palate closure will be prescribed soft palate strengthening exercises for at least 2 months. The objective of the study is to demonstrate the effect of exercises on soft palate closure and ETF. This pilot study will enroll 30 children between ages 6-17 years with VTs or post-VT extrusion tympanic membrane (TM) perforations. All 30 children will have ETD, with active muscular dysfunction. 15 subjects will have a history of cleft palate (CP) and 15 no history of CP. Subjects will undergo history, physical examination including an ENT exam, video-otoscopy and ET function testing which may include Forced Response Test (FRT), Inflation-Deflation Test (IDT) and Tubomanometry. They will also undergo evaluations for swallow, speech and soft palate function. Enrolled children will then receive instruction on the use their EMST150 exercise device. This device will be used daily for at least 2 months. Subjects will undergo full evaluations for ET function and velopharyngeal incompetence after the 2-month treatment and will then discontinue the use of devices for at least 2 months. After this time, the same testing will be done. Weekly phone calls/emails/texts from study staff will encourage use of the devices as prescribed. The following secondary outcome measures were part of the original study protocol but were eliminated after the start of the COVID-19 pandemic because the tests involved blowing maneuvers and risk of aerosolization. The protocol was modified to only include ETF tests that were necessary to achieve the goals of the study and that were safe for the participants. 'Velopharyngeal pressure after 2 months of exercise compared with baseline' 'Velopharyngeal pressure after 2 months of rest compared with baseline' 'Duration of velopharyngeal closure after 2 months of exercise compared with baseline' 'Duration of velopharyngeal closure after 2 months of rest compared with baseline' 'Ability to maintain velopharyngeal closure after 2 months of exercise compared with baseline' 'Ability to maintain velopharyngeal closure after 2 months of rest compared with baseline' 'Overall success in velopharyngeal closure after 2 months of exercise compared with baseline' 'Overall success in velopharyngeal closure following 2 months of rest compared with baseline' The following other pre-specified outcome measures were removed for the same reason: 'Velopharyngeal pressure after 2 months of rest compared with pressure immediately following 2 months of exercise' 'Duration of velopharyngeal closure after 2 months of rest compared with pressure immediately following 2 months of exercise' 'Ability to maintain velopharyngeal closure after 2 months of rest compared with ability immediately following 2 months of exercise' 'Overall success in velopharyngeal closure following 2 months of rest compared with success immediately following 2 months of exercise' 'Eustachian tube function after 2 months of rest compared with function immediately following 2 months of exercise' was moved from an other pre-specified outcome measure to a secondary outcome measure due to its similar level of importance to the other secondary outcome measures. Pressure chamber results were removed from outcome measures because they were unable to be obtained safely during the COVID-19 pandemic.

Interventions

DEVICEEMST150

The EMST150 consists of a handheld plastic tube with a mouthpiece on one end and an adjustable valve on the other end. Your child will close his/her lips around the mouthpiece and breathe out against resistance. The EMST150 will be adjusted to the point where airflow stops. Each day, your child will blow into the EMST150 5 sets of 5 times with a 10-15 second rest between each use and a 1-2 minute rest between each set of 5. You will adjust the resistance of the device each week, take a picture of the device settings, and document exercise sets performed in an exercise diary. These exercises will be performed twice in each nostril 2 times a day until your child's next visit at the MEPL (at least 8 weeks). Each session should take approximately 10-15 minutes, for a total of 30 minutes per day.

EMST150 + Eustachi
Subjects with or without cleft palate will use the EMST150 and Eustachi 2 times a day for 8 weeks. The Eustachi has a handle attached to a nose probe that delivers a constant airflow into the nose. The Eustachi is turned on and while one nostril is pinched with one finger, the nose probe is sealed in the other nostril. Your child will swallow 5 times and will complete an exercise diary recording whether a popping or pressure change was felt in the left, right, or both ears. This exercise sequence will be performed twice in each nostril 2 times a day until your child's next visit at the MEPL (at least 8 weeks). Each session should take approximately 10-15 minutes, for a total of 30 minutes per day.

Eustachian Tube Function at 2 Months

Percent change in middle ear pressure equilibrated during the inflation-deflation test at 2 months

Time frame: 2 months

Population: In the EMST150 group, 2 participants were excluded because the inflation-deflation test was not able to be performed at visit 2 (due to patulous Eustachian tube or the ventilation tube being blocked). 1 participant was lost to follow-up. 3 ears with intact tympanic membranes from 3 participants were excluded~2 participants in the EMST150 + Eustachi group were excluded from analysis. 1 was lost to follow-up after visit 1 and the other was unable to complete visit 2 prior to COVID restrictions.
