DSF - Depressed Skull Fracture: Management & Protocol

• GCS: 13/15 (mild-to-moderate head trauma)
• Provisional Diagnosis: DSF (m' point) PC - likely Depressed Skull Fracture with a midpoint/mid-vault location, with PC = Plan of Care / Post-Concussion

What is a Depressed Skull Fracture?

Types

Clinical Assessment

• 15 = Normal
• 13-14 = Mild impairment
• 9-12 = Moderate TBI
• 8 or less = Severe TBI / coma

• Level of consciousness (GCS)
• Pupillary reactions (asymmetry = danger sign)
• Any focal neurological deficit (weakness, speech problems)
• Signs of open/compound fracture (visible bone, scalp laceration over fracture)
• Signs of CSF leak (clear fluid from nose or ears)

Investigations

1. CT scan of head - most important; shows degree of depression, intracranial hemorrhage, pneumocephalus (air inside skull), and midline shift
2. Plain skull X-ray - can show fracture, but CT is preferred
3. CBC, coagulation profile - to check for bleeding tendencies
4. Blood group & cross-match - if surgery may be needed

Management Protocol

Conservative (Non-operative) Management

• No evidence of dural penetration (no pneumocephalus on CT)
• No significant intracranial hematoma
• Bone depression is less than 1 cm (less than the thickness of the skull table)
• No frontal sinus involvement
• No cosmetic deformity of concern
• No gross wound contamination
• No neurological deficit

Surgical Management - Indications

Medical Treatment (All DSF Patients)

1. Antibiotics - Routinely recommended by the Guidelines for Surgical Management of Depressed Cranial Fractures, especially for open fractures (to prevent meningitis/osteomyelitis)
2. Anti-epileptics - e.g., Levetiracetam (Keppra) 1g loading dose for patients with evidence of intracranial hemorrhage or depressed fracture, to prevent post-traumatic seizures
3. Analgesics - For pain control
4. Tetanus prophylaxis - For open/compound fractures
5. Anti-edema measures - Mannitol or hypertonic saline if cerebral edema is present
6. Nursing position - Head end elevated 30 degrees to reduce ICP
7. Monitor vitals - Especially BP, oxygen saturation, and GCS every 30 minutes

Monitoring Protocol

• GCS every 30 minutes in the ED/ward
• Watch for: worsening headache, vomiting, confusion, seizure, pupil changes, limb weakness
• Repeat CT if GCS drops by 2 or more points
• ICP monitoring if GCS drops to 8 or below

When to Urgently Escalate

• GCS drops significantly (e.g., from 13 to 10 or below)
• Pupils become unequal or non-reactive
• Patient develops seizures
• New focal neurological deficit appears
• CT shows midline shift > 5 mm or hematoma > 10 mm thick

Prognosis

• Post-traumatic seizures (especially in first week)
• Infection (meningitis, brain abscess) - in open fractures
• Post-concussion syndrome - headache, dizziness, cognitive symptoms lasting weeks

Important note: This information is for educational purposes. The treating doctor and neurosurgery team should guide all clinical decisions based on the CT findings, the patient's full examination, and the specific fracture characteristics.

⚠️ URGENT - This Patient Needs Neurosurgery Assessment NOW

What the CT Shows - Breaking It Down

1. Temporal Bone Depressed Fracture (inward displacement)

• The middle meningeal artery runs in a groove just inside the temporal bone. If it tears, it causes an Epidural Hematoma (EDH) - a blood clot that builds up fast and can kill within hours
• The temporal lobe sits directly under this bone and controls speech, memory, and some vision

2. Air on the CT (Pneumocephalus)

• The fracture is communicating with the outside (open fracture)
• Risk of meningitis is now high
• This alone is a reason to go to the operating room

The Patient's Symptoms Explained

• Wernicke's area - understanding speech (dominant side)
• Visual pathways (Meyer's loop) - lower visual field
• Memory circuits

Surgical Indications Present in This Patient

What Should Happen RIGHT NOW

Immediate Actions:

1. Inform the treating doctor/neurosurgeon IMMEDIATELY about the new neurological symptoms - the confusion getting worse, inability to follow commands, vision problem, and speech behavior
2. Do NOT leave this patient alone - he needs constant neurological observation
3. GCS must be re-checked every 15-30 minutes and any drop documented urgently
4. Check pupils - if one pupil is larger than the other or not reacting to light, this is a brain herniation emergency - call for help immediately

Medical Orders Expected:

• IV antibiotics (prophylaxis - dural breach confirmed by pneumocephalus)
• Anti-epileptics (Levetiracetam/Keppra - high seizure risk with temporal lobe injury + depressed fracture)
• Mannitol or hypertonic saline if ICP is rising
• Keep head elevated 30 degrees
• NPO (nothing by mouth) - he may need surgery
• Neurosurgery consultation urgently if not already done

Red Flag Signs - Go to Doctors Immediately If You See:

Please tell the doctor everything you told me - the confusion getting worse, the speech problem (cutting the call instead of talking to wife), and the vision issue. These are new neurological deficits that change the urgency of his management. The pneumocephalus on CT + these symptoms = strong case for neurosurgical intervention.

Latest Neurosurgical Guidelines: Depressed Temporal Fracture + Pneumocephalus

1. Brain Trauma Foundation (BTF) Guidelines - Official Position

Surgical Indications (Level III Evidence - BTF)

For this patient: pneumocephalus + neurological deficits (confusion, aphasia, vision problems) = at minimum 2 BTF surgical indications already met.

2. Temporal Bone Location - Specific Dangers

• Middle meningeal artery lies in a groove along the inner surface of the temporal bone - fracture can tear it, causing epidural hematoma (EDH) that can double in size within hours
• Wernicke's area (left temporal lobe) - damage = receptive aphasia (patient hears but cannot understand - this matches what you described: cutting the call instead of speaking)
• Meyer's loop (visual radiation fibers pass through temporal lobe) - damage = contralateral upper visual field loss
• Temporal lobe herniation (uncal herniation) - dilated pupil on the same side, dropping GCS = neurosurgical emergency

3. Pneumocephalus - 2025 Evidence-Based Algorithm

Key Findings:

• For tension pneumocephalus (air causing brain compression, "Mount Fuji sign" on CT), urgent surgical decompression is mandatory - burr hole, craniotomy, or endoscopy

4. BTF 2026 Update - Penetrating TBI Guidelines

• Early surgical intervention prioritized over delayed
• Antibiotic prophylaxis mandatory
• ICP monitoring for any GCS < 9

5. Surgery vs. Conservative - What Recent Evidence Shows

• Overall neurological outcomes were statistically similar between surgery and conservative groups at 6 months (Glasgow Outcome Scale, p=0.13)
• However, GCS score at admission, presence of focal neurological deficit, and compound fracture were the strongest predictors of worse outcome - requiring surgical intervention
• The key insight: patients with neurological deficits who had surgery did not do worse than those managed conservatively - but those with deficits who were NOT operated had the same complication rates, meaning the deciding factor is the individual clinical picture

• 91% achieved full recovery after surgery
• 9% had residual deficits (hemiparesis, aphasia)
• Worse outcomes linked to: low GCS, compound fracture, presence of hemiparesis, epidural hematoma

6. Antibiotic Protocol (Guideline-Level Recommendation)

7. Anti-Epileptic Protocol

• Levetiracetam (Keppra) 1g IV loading dose, then 500 mg BD - for all DSF with intracranial injury or neurological deficit
• Prophylaxis for 7 days post-injury (early seizures)
• For late seizures (> 7 days), treatment is based on EEG/clinical occurrence

Summary: What Guidelines Say About THIS Patient

Bottom line from current guidelines: This patient has multiple converging surgical indications per BTF and current literature. The neurosurgery team must be at bedside evaluating this patient. If not already consulted, that is the most urgent action.
