Olfactory loss due to head trauma is a frequent finding. It is attributed to the tearing or severing of the olfactory fibers at the cribriform plate. In contrast, posttraumatic gustatory loss is observed and reported rarely and the underlying mechanism is less understood. Here we present a case of a concomitant post-traumatic anosmia and ageusia. Imaging showed a considerable frontobasal brain damage and it is speculated that the gustatory impairment is due to a central injury of the secondary taste cortex. Based on this observation, we believe that this clinical presentation might be much more frequent than previously reported.
头部外伤导致的嗅觉丧失是常见的发现。这归因于筛板处嗅神经纤维的撕裂或离断。相比之下,创伤后味觉丧失的观察和报道很少,其潜在机制也鲜为人知。在此,我们报告一例创伤后嗅觉丧失和味觉丧失同时存在的病例。影像学检查显示额底部脑损伤严重,推测味觉障碍是由于二级味觉皮层的中枢损伤所致。基于这一观察结果,我们认为这种临床表现可能比之前报道的更为常见。
