the investigators hypothesize that Ambu aura-i LMA can be used safely in patients undergoing craniotomies and are effective in reducing the incidence of emergence hypertension.
In this study the investigators want to assess the safety of using SGA devices in cranial surgery and comparing the effect of these devices with ETT regarding hemodynamics stability throughout the procedure and intracranial tension.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| The ETT group | Oral endotracheal intubation via direct laryngoscopy will be performed. The ETT cuff will be inflated to 25 cmH2O using a manometer. | ||
| The LMA group | The Ambu aura-i LMA size will be chosen and inserted using the recommended single-handed rotational technique. Subsequently, a manometer was used to inflate the cuff to 60 cm H2O. |
