本研究的目的是通过量化THS期间咽后壁（PPW）前隆起来阐明THS对咽壁的影响。此外，还分析了舌前突长度对咽壁前突程度的影响。1/3名健康受试者（6名男性和7名女性，2/3 -43岁）在吞咽唾液（SS）和THS期间以两种舌头突出长度（THS 1突出舌头多达预先测量的最大舌头突出长度（MTP-L）的1/3，THS 2突出舌头多达MTP-L的2/3）接受320排区域探测器CT。为了获取静止时咽部的图像，在正常呼吸期间进行三次单相容积扫描，其中无舌突出（静止），舌突出1/3 MTP-L（rTHS 1）和舌突出2/3 MTP-L（rTHS 2）。测量从颈椎到PPW的长度（PPW-AP）和咽腔体积，并在静息、rTHS 1和rTHS 2之间以及SS、THS 1和THS 2之间进行比较。在SS、THS 1和THS 2三种条件下计算MTP-L和PPW-AP之间的相关性。静息时PPW-AP、rTHS 1和rTHS 2分别为2.9 ± 0.6 mm、3.0 ± 0.5 mm和3.0 ± 0.5 mm，显示吞咽间无显著差异。SS、THS 1和THS 2中最大咽部收缩处的PPW-AP分别为8.1 ± 2.0 mm、9.1 ± 2.4 mm和8.7 ± 2.0 mm。与SS相比，THS 1中的PPW-AP显著更大（p = 0.04），THS 2中的PPW-AP无显著差异（p = 0.09）。静息、rTHS 1和rTHS 2时的咽体积分别为16.4 ± 5.2 mm 3、18.4 ± 4.5 mm 3和21.3 ± 6.2 mm 3。与静息或rTHS 1相比，rTHS 2期间显著更大（rTHS 2-静息p = 0.007，rTHS 2-rTHS 1 p = 0.007）。除1例受试者外，所有受试者在咽部最大收缩时咽部体积完全消失（零体积）。在三种条件（SS、THS 1和THS 2）中的任何一种条件下，MTP-L和PPW-AP之间均无相关性。本研究证实，THS时，由于舌突出而导致的咽腔扩张可通过咽壁向前运动的增加而完全消失。同时也很清楚，在THS过程中，舌突出的程度与PPW的运动并不线性相关。PPW运动和MTP-L之间没有关系，这表明通过使用成像工具分析PPW的运动，可以更好地确定每个受试者的舌突出效果。
The purpose of this study was to elucidate the effects of the tongue‐hold swallow (THS) on the pharyngeal wall by quantifying posterior pharyngeal wall (PPW) anterior bulge during the THS. In addition, the effect of tongue protrusion length on the extent of pharyngeal wall anterior bulge was analysed. Thirteen healthy subjects (6 males and 7 females, 23–43 years) underwent 320‐row area detector CT during saliva swallow (SS) and THS at two tongue protrusion lengths (THS1 protrude the tongue as much as 1/3 of premeasured maximum tongue protrusion length (MTP‐L) and THS2 protrude the tongue as much as 2/3 of MTP‐L). To acquire images of the pharynx at rest, single‐phase volume scanning was performed three times during usual breathing with no tongue protrusion (rest), protrusion of the tongue at 1/3 of MTP‐L (rTHS1) and protrusion of the tongue at 2/3 of MTP‐L (rTHS2). Length from cervical spine to PPW (PPW‐AP) and the volume of pharyngeal cavity was measured and was compared between rest, rTHS1 and rTHS2 and between SS, THS1 and THS2. Correlation between MTP‐L and PPW‐AP was calculated in three conditions, SS, THS1 and THS2. PPW‐AP at rest, rTHS1 and rTHS2 was 2.9 ± 0.6 mm, 3.0 ± 0.5 mm and 3.0 ± 0.5 mm, respectively, showing no significant differences across swallows. PPW‐AP at the maximum pharyngeal constriction was 8.1 ± 2.0 mm, 9.1 ± 2.4 mm and 8.7 ± 2.0 mm in SS, THS1 and THS2, respectively. Compared to SS, PPW‐AP in THS1 was significantly larger (p = 0.04) and PPW‐AP in THS2 was not significantly different (p = 0.09). Pharyngeal volume at rest, rTHS1 and rTHS2 was 16.4 ± 5.2 mm3, 18.4 ± 4.5 mm3 and 21.3 ± 6.2 mm3, respectively. It was significantly larger during rTHS2 compared with rest or rTHS1 (rTHS2‐rest p = 0.007, rTHS2‐rTHS1 p = 0.007). Pharyngeal volume was completely obliterated (zero volume) at maximum pharyngeal contraction in all except one subject. There was no correlation between MTP‐L and PPW‐AP in any of the three conditions (SS, THS1 and THS2). This study demonstrated that the expanded pharyngeal cavity due to the tongue protrusion was completely obliterated by the increase in anterior motion of pharyngeal wall during THS. It also became clear that the degree of tongue protrusion did not linearly correlate with the movement of PPW during THS. There was no relationship between PPW motion and the MTP‐L, suggesting that the effect of tongue protrusion is better determined in each subject by analysing the motion of PPW using imaging tools.
