Pediatric Adeno-Tonsillar Hypertrophy Treatment Post-Approval Study
This study is a prospective, multi-center, single-arm study of pediatric subjects (age 3-12) with Sleep-Disordered Breathing ("SDB") due to adeno-tonsillar hypertrophy which are treated with the ENTire IRE System.
Subjects will be followed for six (6) months post-treatment. The objective of the study is to provide an ongoing safety and effectiveness assessment of the ENTire IRE System in treating pediatric adeno-tonsillar hypertrophy.

Description
Inclusion Criteria:
- Patients are 3-12 years of age.

- Children with SDB scheduled for adeno-tonsillar surgery after an otolaryngology evaluation.
Exclusion Criteria:

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
|---|---|
|
Experimental: Enlarged tonsil(s) and/or adenoid mass will be reduced by ENTire IRE System.
|
The bi-polar IRE System locally applies short, high-voltage (HV) pulses, increasing the permeability of tissue cells, creating non-thermal irreversible electroporation (NTIRE). The energy is transferred via bipolar forceps handpiece causing irreversible cell membrane perforation and apoptosis resulting in tissue reduction. The clinical effect is anticipated within 2 to 4 weeks post-treatment. |

|---|---|---|

Number of Participants With Device- or Procedure-Related Adverse Events (Bleeding, Readmission, Dehydration, or Emergency Department Visit)
Time Frame: 6 months
|
Evaluation of the following device and/or procedure-related events: bleeding, readmission, dehydration and emergency department visits. |
6 months

Time From Treatment to First Wong-Baker FACES Pain Scale Score of 2 or Below
Time Frame: From procedure until the end of the first week post procedure (7 days)
|
For each participant, the number of days from treatment until the first daily pain score of 2 or below on the Wong-Baker FACES® Pain Scale. Pain is assessed after treatment and then daily for the first 7 days post-procedure. The scale ranges from 0 ("No hurt") to 10 ("Hurts worst"). Minimum value is 0 and maximum value is 10; higher scores indicate more pain (a worse outcome). |
From procedure until the end of the first week post procedure (7 days)

Change From Baseline in OSA-18 Total Score at 3 Months
Time Frame: 3 months post treatment
|
The Obstructive Sleep Apnea-18 (OSA-18) questionnaire is completed by the parent or caregiver at baseline and at 3 months post treatment. The outcome is the change in OSA-18 total score from baseline to 3 months. The questionnaire has 18 questions, each rated from 1 ("None of the time") to 7 ("All of the time"). The total score ranges from 18 (minimum) to 126 (maximum); higher scores indicate more severe symptoms and greater impairment (a worse outcome). No formal hypothesis will be tested. |

Change From Baseline in OSA-18 Total Score at 6 Months
Time Frame: 6 months post treatment
|
The Obstructive Sleep Apnea-18 (OSA-18) questionnaire is completed by the parent or caregiver at baseline and at 6 months post treatment. The outcome is the change in OSA-18 total score from baseline to 6 months. The questionnaire has 18 questions, each rated from 1 ("None of the time") to 7 ("All of the time"). The total score ranges from 18 (minimum) to 126 (maximum); higher scores indicate more severe symptoms and greater impairment (a worse outcome). No formal hypothesis will be tested. |
