The relationship between temporomandibular joint dysfunction and hearing disorders has long been recognized by some healthcare providers (1,2). Fonder reports that "chronic low-grade otitis media is a constant finding in patients who have a disturbance of the stomatognathical structures due to malocclusion" (3). Fingeroth stated that "a constricted maxillary dental arch frequently results in a decrease in nasal permeability...and within this environment a conductive hearing loss may be present" (4). Histological studies confirm the intimate relationship between the TMJ, the tympanic cavity and the eustachian tube (5,6). Nevertheless, craniomandibular origins are frequently overlooked in the medical profession as possible causes for hearing problems. The following case illustrates this point.
颞下颌关节功能障碍与听力障碍之间的关系早已被一些医疗服务提供者所认识（1,2）。方德报告称，“慢性轻度中耳炎在因错牙合导致口颌结构紊乱的患者中是一个常见发现”（3）。芬格罗斯指出，“上颌牙弓狭窄经常导致鼻通气性下降……在这种环境下可能会出现传导性听力损失”（4）。组织学研究证实了颞下颌关节、鼓室和咽鼓管之间的密切关系（5,6）。然而，在医学界，颅下颌起源作为听力问题的可能原因常常被忽视。以下案例说明了这一点。
