Treatment of Frontal Secondary Headache Attributed to Supratrochlear and Supraorbital Nerve Entrapment With Oral Medication or Botulinum Toxin Type A vs Endoscopic Decompression Surgery.
Ontology highlight
ABSTRACT: Importance:Endoscopic surgical decompression of the supratrochlear nerve (STN) and supraorbital nerve (SON) is a new treatment for patients with frontal chronic headache who are refractory to standard treatment options. Objective:To evaluate and compare treatment outcomes of oral medication, botulinum toxin type A (BoNT/A) injections, and endoscopic decompression surgery in frontal secondary headache attributed to STN and supraorbital SON entrapment. Design, Setting, and Participants:Prospective cohort study of 22 patients from a single institution (Diakonessen Hospital Utrecht) with frontal headache of moderate-to-severe intensity (visual analog scale [VAS] score, 7-10), frontally located, experienced more than 15 days per month, and described as pressure or tension that intensifies with pressure on the area of STN and SON. A screening algorithm was used that included examination, questionnaire, computed tomography of the sinus, injections of local anesthetic, and BoNT/A in the corrugator muscle. Interventions:Different oral medication therapy for headache encountered in the study cohort, as well as BoNT/A injections (15 IU) into the corrugator muscle. Surgical procedures were performed by a single surgeon using an endoscopic surgical approach to release the supraorbital ridge periosteum and to bluntly dissect the glabellar muscle group. Main Outcomes and Measures:Headache VAS intensity after oral medication and BoNT/A injections. Additionally, early postoperative follow-up consisted of a daily headache questionnaire that was evaluated after 1 year. Results:In total, 22 patients (mean [SD] age, 42.0 [15.3] years; 7 men and 15 women) were included in this cohort study. Oral medication therapy reduced the headache intensity significantly (mean [standard error of the mean {SEM}] VAS score, 6.45 [0.20] [95% CI, 0.34-3.02; P?
