[Endoscopic-assisted modified cricothyroid membrane approach for laryngeal surgery in patients with difficult airways].

To explore the value of endoscopic-assisted modified cricothyroid membrane approach laryngeal surgery in patients with difficult airways and evaluate its safety. All patients with laryngeal surgery who were hospitalized were evaluated. For the patients with difficult airways those could not be exposed through routine surgical approach, after full communication, we carried out the endoscope-assisted modified loop thyroscopic approach to the thyroid membrane. All the 12 patients completed the operation successfully, and the visual field exposure was satisfactory during the operation. None of the patients had bleeding and glottic and subglottic stenosis after the operation, and the sound recovered satisfactorily. The cricothyroid membrane approach is not a routine choice for laryngeal surgery, but it is significantly better than other surgical methods for patients with difficult airways who are difficult to expose by conventional approaches, and it is a good choice for patients who cannot be exposed by conventional surgical approaches. The choice is worthy of clinical promotion.
