Transtracheal high-frequency jet ventilation in a patient with limited mouth opening for endolaryngeal surgery: A case report

Abstract

In this article, we report a case describing the airway management and anesthetic technique of a 47-year-old male patient undergoingendolaryngeal surgery with extremely limited mouth opening due to previous maxillofacial trauma. An excisional biopsy was plannedafter laryngoscopic examination for a possible pathological right vocal cord irregularity. Anterior open laryngofissure approach undertranstracheal high-frequency jet ventilation was performed after reviewing all possibilities. Neither direct laryngoscopy nor anyendolaryngeal instrument placement was possible in this case. This approach was considered the most preferable choice to providean unobstructed surgical field and safe gas exchange without requiring additional invasive procedure.
