[Direct laryngoscopy and laryngeal microsurgery in children under general anesthesia].

The great local irritability, especially on mechanical agents (giving shock), required the great caution during the laryngeal microsurgery. Local anesthesia lowered the shock risk and assure the safe and precise maneuvers. However, the tracheal tube in the small children larynx limits the visibility. The aim of this work is the description of our experiences in direct laryngoscopy and laryngeal microsurgery in children under general anesthesia, by use of tracheal tube. The significant modification is a metal tube, fixed to the laryngoscope, by which the halothane and oxygen mixture was given constantly. 201 endoscopy and microsurgery maneuvers of the larynx were performed in our Clinic.
