口腔感觉(即,味觉、口腔感觉、鼻后嗅觉)被整合成一种复合的风味感觉,它指导着对健康有长期影响的饮食选择。携带这种输入的神经容易受到来自多个来源的外周损伤(例如,中耳炎、扁桃体切除术、头部损伤),并且由于神经靶标之间的中枢相互作用,这种区域性损伤可以增强口腔中其他部位的感觉。相互抑制控制着这一补偿过程,但个体差异会导致整个口腔结果的变化:有些人不受影响,有些人会经历严重的损失,有些人会遇到感官增加,这可能(如果在生命早期经历过)提高甜脂肪的适口性和体重。幻味、触觉或疼痛感觉(例如,灼口综合征)也可能发生,特别是在那些表达最多味蕾的人中。为了有效地识别和治疗这些疾病,新兴的临床测试测量区域与全口感觉,刺激与幻象提示以及口腔解剖学。允许有效群体比较的尺度方法有力地帮助了这些努力。总的来说,在健康和疾病中测量口腔感觉功能的进展显示出理解神经损伤的各种临床后果的希望。
Oral sensations (i.e., taste, oral somatosensation, retronasal olfaction) are integrated into a composite sense of flavor, which guides dietary choices with long-term health impact. The nerves carrying this input are vulnerable to peripheral damage from multiple sources (e.g., otitis media, tonsillectomy, head injury), and this regional damage can boost sensations elsewhere in the mouth because of central interactions among nerve targets. Mutual inhibition governs this compensatory process, but individual differences lead to variation in whole-mouth outcomes: some individuals are unaffected, others experience severe loss, and some encounter sensory increases that may (if experienced early in life) elevate sweet-fat palatability and body mass. Phantom taste, touch, or pain sensations (e.g., burning mouth syndrome) may also occur, particularly in those expressing the most taste buds. To identify and treat these conditions effectively, emerging clinical tests measure regional vs. whole-mouth sensation, stimulated vs. phantom cues, and oral anatomy. Scaling methods allowing valid group comparisons have strongly aided these efforts. Overall, advances in measuring oral sensory function in health and disease show promise for understanding the varied clinical consequences of nerve damage.
