Differences in the Nasal Respiratory Function after the Treatment of Maxillary Cyst

Objective:To observe the nasal resistance after medical combination treatments of maxillary cyst. Methods: 12 patients with maxillary cyst were selected, all cases were confirmed by sinus CT or MRI examination,disinfect both cheek`s skin and oral vestibular mucosa. Operation should be taken under topical anesthesia or surface anesthesia,check the cases` nasal passages with transanal endoscopic microsurgery,withdraw the cyst fluid with a injector form the top flank of the nose.Then inject the drug of maxillary cyst(which mainly contains iodine and hexadecadro solution )with a proportion of 2:1(i.e., take out 2 ml cyst fluid, inject of 1 ml drugs, and so on).Cyst if can not be normally punctured can undertake the surgery with the assistance of image recorder.We should check the patients` nasal airway resistance (NAR), nasal volumes(NV), and minimalcross. sectional area(MCA) using Eccovision Acoustic Rhinometer (HoodLabs, USA) and Anterior Rhinometer both before and after the treatments.Then deal the data with a computer. Results: 12 patients with maxillary sinus cyst came back to the hospital for a check of sinus CT check after treatment,compared with the data before the treatment,there are visible differences in general R(cmH20/LMi),general NV(cc) and MCA(cm2). (p<;0.05). Conclusion: Medical combination treatments of maxillary cyst is quiet a effective method to the treatment of maxillary cyst,in the mean time it can decrease the nasal resistance caused by maxillary cyst.
