Subcutaneous Air After Closure of a Tracheocutaneous Fistula

Orbital Emphysema: Case Reports and Review of the Literature

“…Finally, a case of subcutaneous eyelid and subconjunctival emphysema was reported to occur after closure of a persistent tracheocutaneous fistula. 39 During this procedure, air was probably initially blown through the trachéal wound into the subcutaneous tissues of the neck and then spread into the face.…”

Massive subcutaneous emphysema after removal of tracheostomy cannula

“…Subcutaneous emphysema, however, can appear after primary closure of a permanent tracheostomy or after surgical closure of a tracheocutaneous fistula. [1][2][3][4] The probable mechanism for massive subcutaneous emphysema in our case was premature closure of the skin over the tracheostomy site by a relatively thin membrane of neo-epithelium and granulation tissue, without closure of the underlying trachea by granulation tissue.…”
