We describe a case in which a repeat minitracheotomy (MT) could not be performed 2 months after the first. The cricothyroid membrane seemed calcified and histological examination showed scar formation with dystrophic calcification and heterotopic bone formation. Scar formation following MT may have caused these alterations making repeat access to the airway through the membrane impossible.
我们描述了一个病例，在首次实施微创气管切开术（MT）两个月后无法再次进行该手术。环状软骨膜似乎发生了钙化，组织学检查显示有瘢痕形成，并伴有营养不良性钙化和异位骨形成。MT术后的瘢痕形成可能导致了这些改变，使得无法再次通过该膜进入气道。
