The lingual branches of the glossopharyngeal nerve were most likely to bring not only gustatory nerves to the postsulcal part of the tongue but also autonomic nerves to the small glands and vessels. Tonsillectomy may injure the ganglion or reduce its function due to scar formation after surgery.
To determine the topographical anatomy of a suggested ganglion cluster along the lingual branches of the glossopharyngeal nerve and to identify the incidence.
In the human pharynges of 12 donated cadavers, we studied the ganglia using routine procedures for paraffin-embedded histology and immunohistochemistry.
Near the palatine tonsil, the lingual branches of the glossopharyngeal nerve often contained ganglion cells (in 9 of 12 specimens). The ganglion cells, 20-40 µ in diameter, were sparsely distributed along a 0.5-3.0 mm length of the nerve course attached to the posterolateral aspect of the superior pharyngeal constrictor. Most of these cells were positive for neuronal nitric oxide synthase, while some were positive for tyrosine hydroxylase. Thus, the ganglion was composed of a mixed population of sympathetic and parasympathetic neurons.
舌咽神经的舌支很可能不仅为舌沟后部带来味觉神经，还为小腺体和血管带来自主神经。扁桃体切除术后可能因瘢痕形成而损伤神经节或使其功能降低。
确定沿舌咽神经舌支的一个假定神经节簇的局部解剖结构并确定其发生率。
在12具捐赠尸体的人类咽部，我们使用石蜡包埋组织学和免疫组织化学的常规方法研究神经节。
在腭扁桃体附近，舌咽神经的舌支常含有神经节细胞（12个标本中有9个）。神经节细胞直径为20 - 40微米，沿附着于咽上缩肌后外侧的神经行程0.5 - 3.0毫米长度稀疏分布。这些细胞大多数对神经元型一氧化氮合酶呈阳性，而一些对酪氨酸羟化酶呈阳性。因此，该神经节由交感和副交感神经元的混合群体组成。
