Anatomical variations of the stylohyoid apparatus are frequent. Two types can occur: an elongation of the stylohyoid ligament, from a long styloid process to a complete ossified structure connecting the skull base to the lesser horn of the hyoid bone, or the existence of supernumerary bones in the stylohyoid fibrous matrix, which sometimes resembles phalanges. These variations are in the majority of cases bilateral and symmetrical. The authors report the case of a 43-year-old male patient who presented with an unusual unilateral complete ossification of the stylohyoid apparatus, associated with vertebral and laryngeal calcifications. Original latest generation CT scan and three-dimensional MRI imagery are provided to illustrate this rare case.
茎突舌骨装置的解剖变异很常见。可出现两种类型：茎突舌骨韧带延长，从长茎突到连接颅底与舌骨小角的完全骨化结构，或茎突舌骨纤维基质中存在额外的骨头，有时类似指骨。这些变异在大多数情况下是双侧对称的。作者报告了一例43岁男性患者，其茎突舌骨装置出现罕见的单侧完全骨化，并伴有椎体和喉部钙化。提供了原始的最新一代CT扫描和三维MRI图像以说明这一罕见病例。
