Frontal Sinus Repair Using Polymethyl Methacrylate After Bifrontal Craniotomy

Area of Science:

• Neurosurgery
• Cranial Surgery
• Neurosurgical Techniques

Background:

• Bifrontal craniotomy often involves opening the frontal sinus, leading to potential postoperative complications.
• Existing frontal sinus closure methods are technically demanding and time-consuming.

Purpose of the Study:

• To evaluate the safety and efficacy of using polymethyl methacrylate for frontal sinus closure.
• To present a simpler alternative for managing the frontal sinus after bifrontal craniotomy.

Main Methods:

• A consecutive series of 52 patients undergoing bifrontal craniotomy for anterior communicating artery aneurysms had their frontal sinuses filled with polymethyl methacrylate.
• Data were collected from December 2008 to June 2018.

Main Results:

• The mean follow-up duration was 21.8 months, with a maximum of 116 months.
• No instances of cerebrospinal fluid leakage or other surgical complications were reported in the study cohort.

Conclusions:

• Frontal sinus closure with polymethyl methacrylate is a safe and complication-free method.
• This technique represents a valuable option for frontal sinus management in neurosurgery.
