ABSTRACT
OBJECTIVE@#The method of three-dimensional reconstruction of CT images is adopted to evaluate the effects of the plastic operation on upper respiratory tract at one-stage (stage one) for patients with multi-level obstructive sleep apnea hypopnea syndrome.@*METHOD@#Polysomnography is used to diagnose patients with OSAHS. The obstruction parts of patients with OSAHS are determined by CT and endoscopy examinations in the upper air way. To reconstruct the tri-dimensional cavity of upper respiratory tract from data, the CT examinations on the sinuses and nasopharynx are rescanned to obtain the CT data after surgery. The changed situations before and after surgery are compared, and the narrow parts of the upper respiratory tract can be identified and measured intuitively.@*RESULT@#Symptoms and PSG test results show that the effects of the surgical results are very good. and the cross sections of upper respiratory tract narrow parts were enlarged by more than 100%. Hydromechanical evidence approved the same results.@*CONCLUSION@#Calculating the increment of the cross sections of the upper respiratory tract through tri-dimensional reconstruction can not only find the preoperative stenosis, but also assess the surgical effects objectively. Since the body of endoscope has a certain volume, surface anesthesia is needed to enter the nasal cavity and nasopharyngeal which will impact the objectivity of the assessment of the upper respiratory tract stenosis.
