PURPOSE
This study aimed to evaluate and predict the factors that affect the postoperative maxillary sinus and inferior nasal cavity conditions after Le Fort I osteotomy.
SUBJECTS AND METHODS
The rate of aerated (healthy) sinus area and the inferior nasal airway area were calculated by preoperative computed tomography measurements and at 1 week and 1 year postoperatively. Factors predicting the rate of aerated sinus area and the ratio of the inferior nasal cavity area after 1-week were examined using these variables.
RESULTS
The subjects consisted of 112 patients (224 sides) who underwent Le Fort I osteotomy with sagittal split ramus osteotomy. The rate of aerated sinus area after 1 week was significantly correlated with sex, age, and amount of blood loss ( P < 0.0001). The rate of the inferior nasal cavity area after 1 week was significantly correlated with the anterior impaction amount of the maxilla and the preoperative rate of the inferior nasal airway area ( P= 0.0017).
CONCLUSIONS
This study suggests that attention should be paid to females, older patients, and the amount of blood loss to prevent sinusitis, and larger maxillary impaction at the anterior site should be carefully planned to prevent severe nasal obstruction immediately after Le Fort I osteotomy.
目的
本研究旨在评估和预测影响 Le Fort I 截骨术后上颌窦和下鼻道状况的因素。
对象和方法
通过术前计算机断层扫描测量，并在术后 1 周和 1 年计算充气（健康）窦面积和下鼻气道面积的比率。使用这些变量检查预测术后 1 周充气窦面积比率和下鼻道面积比的因素。
结果
研究对象包括 112 例（224 侧）接受 Le Fort I 截骨术联合下颌支矢状劈开术的患者。术后 1 周充气窦面积比率与性别、年龄和失血量显著相关（P<0.0001）。术后 1 周下鼻道面积比率与上颌骨前向撞击量和术前下鼻气道面积比率显著相关（P=0.0017）。
结论
本研究表明，应注意女性、老年患者和出血量，以预防鼻窦炎，并且应仔细计划上颌骨前部更大的撞击量，以防止 Le Fort I 截骨术后立即出现严重的鼻塞。
