Objective:
Migraine affects more than 35 million people in the United States of America, and 10% of the population in the world. The purpose of this study was to evaluate the effectiveness of surgical treatment in chronic migraine with frontal or occipital trigger areas.
Methods:
We designed a pilot, proof of concept, and prospective study to analyze the effectiveness of surgical release of trigger nerves in severe frontal or occipital chronic migraines. The study was approved by the Ethics and Investigation Committee of Hospital Universitario Dr. José Eleuterio González (Monterrey, N.L., Mexico). We included patients diagnosed with chronic migraine by the neurology service of Hospital Universitario Dr. José Eleuterio González that attended our consult from March to December 2012. The patients were assessed by the MIDAS questionnaire and the diagnosis confirmed by injecting 2% lidocaine in the trigger sites. We realized a superior palpebral approach in frontal migraines to resection the glabellar muscles and an occipital approach to free the greater occipital nerve bilaterally. We evaluated complete and partial clinical response measuring the frequency, intensity, and duration of migraine episodes.
Results:
We included three patients with Stage IV (severe incapacitating) frontal or occipital chronic migraines. Two were occipital trigger sites and one frontal. We obtained complete clinical response in two patients and a partial response in one. Pain intensity decreased in all patients.
Conclusion:
Surgical treatment is effective in Stage IV (severe incapacitating) frontal or occipital trigger chronic migraines.

Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
