Disturbances of smell and taste after high central midface fractures.
Estimation of the senses of smell and taste in patients who had suffered a high central midface fracture between 1979 and 1989 was carried out. 180 of these patients were operated on for repositioning and fixation of their fractures. A written questionnaire was sent to 165 living patients, 109 individuals responded, a response rate of 66%. Of these patients, 38% claimed to suffer impaired ability to smell and 23% not to taste well. 64% mentioned unconsciousness after the trauma. With rising seriousness of the trauma, more disturbances of smell are found: from 25% of the nasal fractures, to 80% of the fronto-nasal-Le Fort fractures. In more than half of the cases of disturbance of smell, a simultaneous impairment of taste was reported. It can be concluded that disturbance of smell most often appears after fronto-maxillary and fronto-nasal fractures. However, the higher and more extensive the fracture is, the more frequently is unconsciousness reported. Consequently, impairment of smell can be attributed to the fracture itself, but also to a cerebral lesion located more proximally.
