To perform the multilateral evaluation of the abnormal tongue movement, the relationship between mandibular movement, tongue muscle activities and the morphologies of the maxillofacial skeletal pattern, and the movement of tongue during swallowing were investigated.1. The distance and the inclination of protruding movements were associated positively with *ANB, overbite and overjet. The inclinations of both anteriorly and posteriorly opening paths were associated positively with *MP-SN, *MP-FH and negatively with S-N and A'-Ptm'. The sagittal area of MBM was associated positively with gonial angle and negatively with A'-Ptm', Cd-Go. The inclination of lateral guided movements was associated positively with overbite.2. Subjects who have burst in anterior temporalis and masseter during swallowing were larger in the short face group, while smaller in the long face group. Timing of the initial burst of genioglossus (GG) and digastricus (DI) during swallowing resulted that GG is ahead of DI in the short and average face groups, therefore, nearly same time in the long face group.3. Type of tongue dorsum movement : In normal swallowing subjects (group NS), there were two types of tongue dorsum movement at the ascending which were direct ascending (type U) or first descending (type D). There were three types after the ascending which were making a clear plateau (type 1), keeping the highest point shortly (type 2) and directly descending (type 3). Consequently, normal swallowing subjects were evaluated as four types of U-1, U-3, D-2 and D-3. Tongue thrusting subjects (group TT) were evaluated as D-2 and D-3.Height, duration and velocity of tongue dorsum movement were compared. No significant differences were seen in the highest point and descending velocity after the ascending. Ascending velocity was faster and duration at the plateau was longer in U-I, while they were slower and shorter in D-2 and D-3.

为了对舌运动异常进行多方面的评价，研究了下颌运动、舌肌活动与颌面部骨骼形态的关系，以及吞咽过程中舌的运动。前牙突起距离和倾斜度与ANB、覆牙合、覆牙合呈正相关。前、后导联倾斜度与*MP-SN、*MP-FH呈正相关，与S-N、A‘-Ptm’呈负相关。MBM矢状面面积与弓角呈正相关，与A‘-PTM’、CD-GO呈负相关。结论：1.侧向引导运动倾斜度与上牙合呈正相关。吞咽时前颞肌和咬肌爆裂的受试者在短面组较大，而长面组较小。吞咽过程中膝舌肌(GG)和二尖肌(DI)的初始爆发的时间，导致GG在短面组和平均面组中领先于DI，因此，在长面组中几乎相同的时间。舌背运动类型：正常吞咽受试者(NS组)舌背升部运动有两种类型，即直接升行型(U型)和先降型(D型)。上升后有三种类型，即形成明显的平台(类型1)、短期保持最高点(类型2)和直接下降(类型3)。因此，正常吞咽受试者被评估为U-1、U-3、D-2和D-3四种类型。比较舌背运动的高度、持续时间和运动速度。上升后的最高点和下降速度无明显差异。U-I上升速度较快，持续时间较长，而D-2、D-3上升速度较慢，持续时间较短。
