title: Treatment of chronic maxillary atelectasis using balloon dilation.
abstract: Balloon dilation may offer a more expedient and cost-effective treatment method compared with traditional endoscopic sinus surgery for chronic maxillary atelectasis. We sought to demonstrate the feasibility of balloon dilation of the maxillary os as a treatment modality for patients with chronic maxillary atelectasis by investigating the short-term outcomes in a retrospective case series of 4 patients representing 5 sinuses treated between 2011 and 2013. All sinuses were successfully balloon dilated without complications. Follow-up ranged from 1 week to 4 months. Aeration of the treated sinuses without restenosis was confirmed by postoperative endoscopy, sinus computed tomography, or both. All patients reported subjective symptomatic improvement. Balloon dilation of the maxillary os may be a feasible treatment option for maxillary sinus atelectasis. Longer follow-up and a larger study sample will be needed to validate the safety of this technique and determine the rate of restenosis.
