different ways of airway management in elective minor surgeries of geriatric patients

The investigators will used two different ways of pro-seal laryngeal mask insertion technique (laryngoscopy- guided technique or the standard technique) in elective minor surgeries of geriatric toothless patients.

The investigators will record the respiratory dynamics, heartbeat, systolic, diastolic, mean arterial pressures every 5 minutes during surgery. The investigators will record the laryngeal mask insertion time and oropharyngeal leakage pressure. The investigators will evaluate the placement of a laryngeal mask according to young criteria. The development and severity of coughing, retching, laryngospasm, extremity, and head movement during laryngeal mask placement will be recorded. Bloodstains, sore throat, hoarseness will be recorded on the mask that may develop due to laryngeal mask placement. The investigators will use the Briacombe scoring and Campbell category system to assess the position of laryngeal mask airway devices.

3. Patients undergoing general anesthesia
4. Those who are planned to wear a laryngeal mask for surgical procedure

Exclusion Criteria:
