Tracheal tube cuff damage usually requires tube replacement; however, in patients with a difficult airway, tube exchange can pose significant risks. We report a case in which cuff damage was successfully managed using an automatic cuff pressure controller. 　The patient was a man in his 70s who was scheduled for posterior decompression and fusion for cervical spondylotic myelopathy while wearing an external spinal fixation device. Awake nasotracheal intubation was performed using a flexible bronchoscope, during which cuff damage was identified. The tracheal tube was exchanged with a Tube Exchanger® but cuff damage recurred, requiring a second exchange using the same method. Although no cuff leak was observed immediately afterward, a gradual decrease in tidal volume developed after repositioning the patient to the prone position. Because the cuff leak was relatively minor, an automatic cuff pressure controller was connected, which maintained tidal volume without further decreases and allowed completion of the surgery. In situations where tube exchange carries high risk, an automatic cuff pressure controller may serve as a temporary rescue measure for cuff damage. The cause of cuff damage in this case was considered to be a nasal septal spur combined with the relatively large tube size.

Deep neck abscess can cause upper airway stenosis and obstruction, and sometimes emergency airway management is required. Here we present a case of deep neck abscess in which awake intubation with a video laryngoscope (McGRATH™ MAC) was more useful than with flexible bronchoscope. A man in his 80s was transported to our hospital with throat and chest pain. Contrast-enhanced computed tomography revealed a deep neck abscess (right peritonsillar abscess). The otolaryngologist attempted drainage by puncture, but this was ineffective. There was a risk of upper airway obstruction, and emergency airway management was required. First, we attempted endotracheal intubation with a flexible bronchoscope but could not secure the field of view because of the upper airway edema and stenosis. Next, we attempted tracheal intubation using a video laryngoscope, which ultimately was successful. The blade of the video laryngoscope compressed and lifted the soft tissue and then it secured the space of the upper airway.
