Objective: Although laryngomalacia is a common cause for infantile stridor, few patients eventually go on to require surgical intervention. When surgery is required, the location of tissue excised may vary depending on the endoscopic findings, but only two methods of tissue excision are described-cold knife excision and carbon dioxide laser. We present our experience of using the microdebrider to excise tissue during supraglottoplasty.
Methods: Over the last 12 months, patients were identified who had undergone supraglottoplasty, and their final outcomes with regards to resolution of stridor, cor pulmonale, and/or failure to thrive were assessed. A description of the indications for supraglottoplasty and the actual technique utilizing the microdebrider is included.
Results: Five patients were identified as having undergone a microdebrider-assisted supraglottoplasty. All five had resolution of their stridor following surgery. No new complications such as aspiration or supraglottic stenosis were identified. No revision surgeries were required. The microdebrider was used to trim the aryepiglottic folds and/or redundant arytenoid mucosa in all cases.
Conclusions: The microdebrider appears to be a safe and effective tool to remove redundant tissue during supraglottoplasty.
