95830 Insertion by physician or other qualified health care professional of sphenoidal electrodes for electroencephalographic (EEG) recording

Name of the Procedure:

Insertion by physician or other qualified health care professional of sphenoidal electrodes for electroencephalographic (EEG) recording.

Summary

In layman's terms, this procedure involves placing specialized electrodes near the sphenoid bone at the base of the skull to measure electrical activity in the brain. This helps in diagnosing and understanding certain neurological conditions, such as epilepsy.

Purpose

Medical Conditions or Problems Addressed

• Epilepsy
• Seizure disorders
• Other neurological conditions causing abnormal brain activity

Goals or Expected Outcomes

• Accurate recording of brain electrical activity.
• Identification and localization of abnormal brain areas causing seizures.

Indications

Symptoms or Conditions Warranting the Procedure

• Frequent or unexplained seizures
• Abnormal EEG readings not adequately explained by other tests

Patient Criteria

• Patients with a history of complex partial seizures.
• Candidates for epilepsy surgery evaluation.

Preparation

Pre-Procedure Instructions

• Fasting may be required for a few hours before the procedure.
• Medication adjustments as directed by the physician.
• Remove any hair products and avoid caffeine on the day of the procedure.

Diagnostic Tests or Assessments Required

• Initial EEG recordings.
• Diagnostic imaging (e.g., MRI or CT scan).

Procedure Description

1. Preparation: The patient lies down in a sterile setting.
2. Anesthesia: Local anesthesia is applied to numb the insertion site.
3. Insertion: Needle electrodes are carefully inserted through the cheek and positioned near the sphenoid bone.
4. Placement Confirmation: Electrode placement is confirmed using imaging technology such as fluoroscopy.
5. Recording: EEG recording is initiated to observe brain activity.

Tools, Equipment, or Technology Used

• Needle electrodes
• Anesthesia supplies
• Imaging technology (e.g., fluoroscopy)

Anesthesia or Sedation Details

• Local anesthesia to numb the insertion site.
• Sedation as decided by the healthcare team.

Duration

The procedure typically takes about 1 to 2 hours.

Setting

The procedure is performed in a hospital setting, often in a specialized EEG monitoring unit or operating room.

Personnel

• Neurologist or specialized physician
• Nurses
• Anesthesiologist (if sedation is used)
• EEG technician

Risks and Complications

Common Risks

• Minor bleeding at the insertion site
• Discomfort or pain at the insertion site

Rare Risks

• Infection
• Damage to surrounding structures
• Adverse reaction to anesthesia

Possible Complications

• Persistent pain or swelling
  • Managed with pain relief and anti-inflammatory medications
• Infection
  • Managed with antibiotics

Benefits

• More accurate identification of seizure origins.
• Enhanced diagnosis and planning for treatment.
• Benefits generally realized soon after the procedure when the recordings are analyzed.

Recovery

Post-Procedure Care

• Monitor the insertion site for signs of infection or complications.
• Follow pain management techniques as advised by the physician.

Expected Recovery Time

• Most patients recover within a few hours to a day.
• Follow-up appointments may be necessary for further assessment or treatment planning.

Alternatives

Other Treatment Options

• Scalp EEG recording
• Other neuroimaging techniques

Pros and Cons of Alternatives

• Scalp EEG is less invasive but may not be as detailed in recording deep brain structures.
• Neuroimaging is useful for structural anomalies but does not provide real-time electrical activity.

Patient Experience

During the Procedure

• Mild discomfort or pressure during electrode insertion.
• Localized numbness due to anesthesia.

After the Procedure

• Possible soreness at the insertion site.
• Mild discomfort that can be managed with pain medication.

Pain Management and Comfort Measures

• Use of prescribed pain relief medications.
• Proper care of the insertion site to avoid infection.
