What is the management for a 20-year-old female with a computed tomography (CT) scan showing a comminuted fracture of the outer table of the frontal calvarium, with displacement of bone fragments into the frontal sinus, anterior ethmoid sinus, and extracranial soft tissues of the left orbit, causing mass effect on the medial extraocular muscles?

From the Guidelines

This patient requires immediate surgical intervention by a multidisciplinary team including neurosurgery, otolaryngology, and ophthalmology to address the comminuted fracture of the outer table of the frontal calvarium and prevent potential complications such as infection, CSF leak, and vision impairment. The treatment should involve surgical debridement, removal of bone fragments, repair of the frontal sinus, and reconstruction of the orbital wall. Preoperatively, the patient should receive broad-spectrum antibiotics such as ceftriaxone 2g IV daily plus vancomycin 15-20mg/kg IV every 12 hours to prevent infection, as well as appropriate pain management with medications like morphine 2-4mg IV every 4 hours as needed 1.

Key Considerations

• A thorough neurological assessment should be performed to rule out intracranial injury, and ophthalmologic evaluation is essential to assess for vision impairment and ocular muscle function given the orbital involvement.
• The use of CT scans, as described in the study by 1, is crucial in evaluating the extent of the fracture and planning the surgical approach.
• Post-operatively, the patient will need continued antibiotics for 7-14 days, regular wound care, and close follow-up to monitor for complications such as CSF leak, meningitis, mucocele formation, or vision changes.

Surgical Approach

• The surgical approach should involve a multidisciplinary team to address the complex nature of the fracture and prevent potential complications.
• The use of 3-D image reconstructions, as described in the study by 1, can aid in preoperative planning and ensure a more accurate and effective surgical approach.
• The patient's condition and potential complications should be closely monitored post-operatively to ensure prompt intervention if necessary.

Potential Complications

• The patient is at risk of developing complications such as CSF leak, meningitis, mucocele formation, or vision changes due to the comminuted fracture and displacement of bone fragments into the sinuses and orbit.
• Close follow-up and monitoring are essential to prevent or promptly address these potential complications 1.

From the Research

Management of Comminuted Fracture

The management of a comminuted fracture of the outer table of the frontal calvarium, with displacement of bone fragments into the frontal sinus, anterior ethmoid sinus, and extracranial soft tissues of the left orbit, involves several key considerations:

• Early diagnosis and intraoperative comprehensive exploration are necessary due to the complexity and severity of the trauma 2
• A rational design for a secondary operation may be required to deal with possible retained foreign bodies and other postoperative complications such as cerebrospinal fluid (CSF) leak 2
• The use of computed tomography, including plain scan, three-dimensional reconstruction, and computed tomographic angiography, can help determine the course and extent of the head injury 2
• Surgical intervention, such as a frontal craniotomy, may be necessary to remove bone fragments and repair defects 2

Surgical Techniques

Various surgical techniques can be used to manage comminuted fractures, including:

• Plate fixation, which has been used to treat comminuted olecranon fractures 3
• Open reduction and internal fixation (ORIF), which can be used to treat comminuted distal femur fractures 4
• Guided bone regeneration (GBR), which can be used to preserve the alveolar ridge after a comminuted fracture of the anterior maxilla 5
• Double ligature technique, which can be used to treat comminuted midshaft clavicle fractures with bone fragments separated by soft tissue 6

Postoperative Care

Postoperative care is crucial to optimize functional outcomes and prevent complications:

• Aggressive broad-spectrum antibiotics may be administered to prevent infection 2
• CSF external drainage system may be used to manage CSF leak 2
• Physical rehabilitation, including early mobilization, proprioceptive training, and tailored exercise regimens, can help restore joint mobility and enhance muscular strength 4
