Name of the Procedure:

Cranioplasty for skull defect; larger than 5 cm diameter

Summary

Cranioplasty is a surgical procedure to repair or reconstruct a skull defect larger than 5 cm in diameter. The surgery involves the use of custom-made implants or grafts to restore the normal shape and function of the skull.

Purpose

Cranioplasty addresses conditions such as traumatic skull injuries, congenital deformities, or defects left after surgical resections. The goals are to protect the brain, restore the appearance of the skull, and improve overall functionality.

Indications

• Traumatic injuries resulting in skull defects
• Congenital skull deformities
• Defects following tumor removal or decompressive craniectomy
• Patient discomfort or self-consciousness due to skull irregularities

Preparation

• Patients may need to fast for 8-12 hours before the surgery.
• Preoperative assessments will include blood tests, imaging studies like CT scans, and a thorough medical and surgical history review.
• Medications may need adjustment, particularly blood thinners and anti-inflammatory drugs.

Procedure Description

1. The patient is placed under general anesthesia.
2. An incision is made over the area of the skull defect.
3. The surgeon prepares the defect area and meticulously fits the customized implant or bone graft.
4. The implant is secured using plates, screws, or other fixation devices.
5. The incision is closed with sutures or staples, and a sterile dressing is applied.

Tools and technology:

• Customized 3D-printed implants or bone graft materials
• Surgical instruments: scalpels, drills, fixation devices
• Imaging technology for preoperative planning

Duration

Typically, the procedure takes about 2-4 hours, depending on the complexity and size of the defect.

Setting

The procedure is performed in a hospital operating room.

Personnel

• Neurosurgeon or craniofacial surgeon
• Anesthesiologist
• Surgical nurses and technicians

Risks and Complications

• Infection
• Bleeding or blood clots
• Implant rejection or failure
• Surgical site discomfort or pain
• Cerebral edema (brain swelling)
• Seizures

Benefits

• Protection of underlying brain tissue
• Improved cosmetic appearance
• Alleviation of psychological distress related to skull deformity
• Enhanced functional outcomes, such as improved neurological status

Recovery

• Patients may need to stay in the hospital for several days post-surgery.
• Follow post-operative care instructions meticulously, including wound care and medication adherence.
• Limit physical activity for several weeks; gradual return to normal activities as advised by the surgeon.
• Follow-up appointments are essential for monitoring recovery and implant stability.

Alternatives

• Observation and nonsurgical management for small defects or asymptomatic patients.
• Using different materials for the reconstruction, such as autologous bone grafts vs. synthetic implants.

Pros and cons of alternatives:

• Non-surgical approaches avoid surgical risks but do not address larger defects or provide the protective and cosmetic benefits of cranioplasty.
• Autologous bone grafts have lower rejection rates but may involve additional surgery and extended recovery time.

Patient Experience

• During the procedure, the patient will be under general anesthesia and will not feel anything.
• Post-surgery, patients may experience soreness, headache, and swelling around the surgical site.
• Pain management will include prescribed pain relievers and comfort measures such as ice packs.
• Gradual improvement in cognitive and physical functions is expected as the healing progresses.
