UNLABELLED: There is no consensus regarding which type of endotracheal tube or method of fixation should be employed in neonates. We use oral endotracheal tubes held in place by a flange tied to a bonnet. In three very preterm infants the ligatures holding the bonnet to the flange caused pressure necrosis to the ear while the infants suffered poor perfusion due to profound hypotension. Permanent ear deformities have resulted. CONCLUSION: extra vigilance and precautions are required to prevent iatrogenic problems in sick, very prematurely born infants.
Trauma and tumor are the causes of acquired ear defects that surgeons are frequently called on to treat. Trauma may result in hematoma or laceration of the ear. In addition, both trauma and tumor excision may result in skin or cartilage loss. Prevention of recurrence depends on complete excision of the tumor m both lateral margins and depth. Tumors of the ear (as well as the nose) are often incompletely excised because of the difficulty in reconstruction. The absence of subcutaneous tissue in the ear allows fixation and perichondrial involvement to occur early. The tumor affinity for perichondrium usually prohibits penetration into the cartilage itself.
