Laryngeal microsurgery without intubation

Area of Science:

• Otolaryngology
• Anesthesiology
• Microsurgery

Background:

• Suspension microsurgery requires clear visualization of the glottic space.
• Traditional intubation methods can obstruct the surgical field.
• Alternative oxygenation techniques are needed for endolaryngeal procedures.

Purpose of the Study:

• To evaluate the safety and efficacy of Venturi insufflation oxygenation during endolaryngeal suspension microsurgery.
• To assess the impact of this technique on patient oxygenation and blood gas levels.

Main Methods:

• Review of 200 endolaryngeal suspension microsurgical cases.
• Utilized intravenous anesthesia and Venturi insufflation oxygenation.
• Included adult and pediatric patient populations (20 months to 88 years).

Main Results:

• No significant complications were reported in any of the 200 cases.
• The technique successfully maintained a clear glottic surgical field.
• Arterial blood gas studies confirmed adequate oxygenation and normal pH/PaCO2 levels.

Conclusions:

• Venturi insufflation oxygenation is a safe and effective method for endolaryngeal suspension microsurgery.
• This technique provides adequate physiological support during these procedures.
• It offers a viable alternative to traditional intubation, improving surgical access.
