Introduction
Surgery involving a single frontal lobe resection is now rare. In the past, such procedures were occasionally performed for epilepsy or psychiatric disorders, but they are virtually obsolete today. The frontal lobe—particularly its anterior portion—is relatively vulnerable in the human brain. Resection of part of the frontal lobe, especially the right frontal lobe, generally does not result in severe consequences or functional impairment, provided that no critical functional areas are involved; thus, the impact on the patient remains minimal.

Frontal lobectomy is a surgical procedure historically used to help stabilize patients with psychiatric disorders. However, this surgery carries substantial risks and causes significant harm to the human body. What are the consequences of frontal lobectomy?

Consequences of Frontal Lobectomy

Unilateral frontal lobectomy is now extremely rare. In the past, it was occasionally performed for epilepsy or psychiatric conditions, but it is virtually obsolete today. The frontal lobe is relatively vulnerable in the human brain—particularly its anterior portion. If the resection avoids critical functional areas, partial removal—especially of the right frontal lobe—typically results in minimal functional impairment and does not significantly affect the patient’s daily functioning. However, certain regions within the frontal lobe must never be resected. For example, the posterior portion of the superior frontal gyrus contains Broca’s area—the motor speech center. Damage or removal of this region leads to expressive aphasia, characterized by an inability to produce spoken language.

The precentral gyrus—also part of the frontal lobe—controls voluntary movement of the contralateral side of the body. Injury to this region results in contralateral paralysis; therefore, it must never be resected. When partial resection is performed outside of essential frontal lobe functional areas, severe functional deficits are generally avoided.

After surgery, patients should prioritize rest, consume light and easily digestible foods, and avoid spicy or otherwise irritating foods. Bedrooms should be well-ventilated by opening windows regularly. We hope this information is helpful to you.
