Abstract
A prospective randomized controlled study was conducted to investigate the effect of balloon catheter dilation technology combined with a fibrolaryngoscope in the treatment of a maxillary sinus cyst. The clinical data of 14 cases (19 maxillary sinuses) with balloon catheter dilation technology combined with a fibrolaryngoscope to remove sinus cysts (balloon group) and 16 cases (23 maxillary sinuses) with conventional nasal endoscopic sinus surgery to remove sinus cysts (conventional group) were analyzed. All cases have completed the preoperative and postoperative SNOT-20, nasal endoscopy and coronal sinus CT scan. Lund-Kennedy endoscopic and Lund-Mackay CT scan staging scores were recorded. All patients were followed up for 24 weeks after the operation. The SNOT-20 scores, Lund-Kennedy endoscopic and Lund-Mackay CT scan staging scores were lower in the balloon group than that in the control group. Balloon catheter dilation technology combined with a fibrolaryngoscope can effectively preserve the function and structures of the nasal cavity and sinus, making it a good choice in the treatment of a retention cyst of the maxillary sinus.
