Coblation-Tonsillotomy vs Electrocautery-Tonsillectomy for the Treatment of Obstructive Sleep Apnea (OSA) in Children - Full Text View

Purpose

Removal of the adenoid and tonsils, known as an adenotonsillectomy (AT) is one of the most frequently performed surgical procedures in North America. The two most prevalent indications for this procedure in children are recurrent bacterial tonsillitis and obstructive sleep apnea (OSA). OSA is a common childhood condition that is characterized by upper airway obstruction, disturbed sleep and disrupted normal respiratory gas exchange. In the majority of children with OSA, overgrowth of the adenoid and tonsils is the primary underlying aetiology, making tissue removal via AT the standard of care. The purpose of this study is to evaluate the effectiveness of two different surgical techniques, electrocautery-tonsillectomy and coblation-tonsillotomy, in the treatment of obstructive sleep apnea (OSA) in children.

Further study details as provided by University of Calgary:

Primary Outcome Measures:

Compare coblation-tonsillotomy to electrocautery-tonsillectomy as a treatment of obstructive sleep apnea (OSA), as assessed by apnea-hypopnea index (AHI) measured on polysomnography (PSG) [ Time Frame: 6 months and 2 years post-op ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Evaluate post-operative pain and analgesic use associated with electrocautery-tonsillectomy and coblation-tonsillotomy [ Time Frame: 1 week post-op ] [ Designated as safety issue: No ]
Evaluate quality of life following coblation-tonsillotomy and electrocautery-tonsillectomy for the treatment of OSA [ Time Frame: 6-8 weeks post-op ] [ Designated as safety issue: No ]
