Sinus problems as a cause of headache refractoriness and migraine chronification

Medication overuse headache: a review of current evidence and management strategies

The third edition of the International Classification of Headache Disorders (ICHD-3) defines medication-overuse headache (MOH) as a headache that develops when a person regularly uses acute or symptomatic headache medications excessively (10 or more, or 15 or more days per month, depending on the medication) for a period of time longer than 3 months. Even though it may not be reported as frequently as it actually is, it affects about 5% of the general population on average. It typically happens following repeated anti-pain medication use for pre-existing headache disorders, such as migraines. Anti-pains can also be used frequently in patients with pre-existing headache disorders for reasons other than treating headaches, such as psychological drug attachment. MOH is linked to a number of illnesses, such as anxiety, depression, and obsessive compulsive disorder (OCD). Both simple and complex types are possible. Additionally, there is no universal consensus on how to treat MOH, but drug discontinuation is the best course of action. Using the medical subject headings "Medication Overuse Headache," "Migraine Headache," "Tension Headache," "Chronification of Headache," and "Antipains," an all-language literature search was done on PubMed, Google Scholar, and Medline up until March 2023. We looked into the epidemiology, risk factors, pathophysiology, clinical characteristics, comorbidities, diagnosis, management, and preventative measures of MOH in the literature. This article focuses on the MOH research themes.

Clinical Outcome Following Endoscopic Septoturbinal Surgeries for Rhinogenic Contact Point Headache: A Retrospective Analysis

To assess the clinical outcome of endoscopic septoturbinal surgeries in patients with rhinogenic contact point headache. Retrospective audit of medical records. Retrospective audit of medical records of patients having undergone endoscopic surgical management for contact point headache between a period of May 2017 to May 2018 were included in the study. Patients who underwent functional endoscopic sinus surgery were excluded from the study. Pre operative pain score were compared with post operative pain score at interval of 1 month for 3 months consequently and at 1 year interval using Visual Analog scale (VAS). The difference between preoperative (mean 6.82) and post operative VAS pain scores after 1 month (mean 3.36), 2 months (mean 4.50), 3 months (mean 5.48), 1 year (mean 5.01) was statistically significant (p < 0.001). Contact point headache is an important clinical entity that might be missed during evaluation and management of refractory headache. Surgical management under endoscopic guidance can help to ensure removal of mucosal contact point and aid in the treatment of refractory headache as noted in our study.

Debunking Myths: Sinus Headache

PURPOSE OF REVIEW

Although sinus headache has been extensively reviewed and described, misdiagnosis remains common. This paper discusses the myths and truths about sinus headaches.

RECENT FINDINGS

Sinus headache is used colloquially to attribute facial pain to allergies or a sinus infection; however, most sinus headaches are migraine. Sinus-region pain from sinusitis and migraine share the same origins in the trigeminovascular system, but their causes are very different. After reviewing sinus anatomy and sinogenic pain, we provide information to assist clinicians in correctly diagnosing patients with the additional goal of avoiding unnecessary investigations and treatments. Migraine medications can be used as both a treatment and a diagnostic tool. Other differential diagnoses of facial pain are discussed. Sinus headache is not a diagnosis. All patients with facial pain or pressure with sinus symptoms should be evaluated for migraine because most sinus headache presentations are migraine and require migraine-directed treatment.

Paranasal sinus volumes and headache: is there a relation?

PURPOSE

The aim of the study is to investigate the relation between paranasal sinus volumes and headache in patients with no other rhinologic causes.

METHODS

Two hundred patients with chronic headache and 99 subjects with no headache or facial pain history in the last 6 months were included in the study. Paranasal computed tomography (CT) scans of both patient and control groups were evaluated. Sixty one patients were excluded from the study due to possible rhinogenic headache CT findings such as secretions and contact points. Sinus volume index (SVI) formula created by Barghouth et al. in 2002 was used to calculate paranasal sinus volumes: SVI = ½. A × B × C. Mann-Whitney U test was used to compare an independent continuous variable and a continuous variable with non-normal distribution.

RESULTS

In the patient group, the total sinus, frontal sinus, and maxillary sinus volumes were found to be significantly lower than those of the control group (p < 0.001). Although the total sphenoid sinus volume was found to be lower in the patient group, there was no significant difference between the two groups (p = 0.013).

CONCLUSION

Although rhinogenic findings are often related to secondary headache, the relation between paranasal sinus volume and headache is scarcely investigated in the literature. Our study showed that paranasal sinus volumes might have a role in secondary headaches. Furthermore, in contrast to the literature, our study showed a significant relation between headache and smaller paranasal sinus volumes.

Rhinogenic Contact Point Headache: Surgical Treatment Versus Medical Treatment

Rhinogenic contact point headache (RCPH) is a headache syndrome secondary to mucosal contact points in the sinonasal cavities, in the absence of inflammatory signs, hyperplastic mucosa, purulent discharge, sinonasal polyps, or masses. It may result from pressure on the nasal mucosa due to anatomic variations among which the septal deviation, septal spur, and concha bullosa, are the most commonly observed. In recent years, RCPH has remained a subject of controversy regarding both its pathogenesis and treatment. This study aimed to investigate the effect of surgical and medical treatment of pain relief in patients with RCPH, evaluating the intensity, duration, and frequency of headaches, and the impact of different treatments on quality of life. Ninety-four patients with headache, no symptoms or signs of acute and chronic sinonasal inflammation and who present with intranasal mucosal contact points positive to the lidocaine test were randomized into 2 equal groups and given medical or surgical treatment. The authors used visual analog scale, number of hours, and days with pain to characterize the headache and Migraine Disability Assessment score (MIDAS) to assess the migraine disability score before and 3 to 6 months after treatment. After treatment the severity, duration, and frequency of the headache decreased significantly (P < 0.001, P < 0.001, and P = 0.031, respectively) as well as the MIDAS in the surgical group compared with medical group. Our results suggest that surgical removal of mucosal contact points is more effective than local medical treatment improving the therapeutic outcomes in patients with contact point headache.

Co-occurrence of migraine and atopy in children and adolescents: myth or a casual relationship?

PURPOSE OF REVIEW

To clarify the causal relationship between migraine and atopic disorders in children and adolescents.

RECENT FINDINGS

Migraine headache and atopic disorders including asthma are both common functional syndromes of childhood in which nature of the relationship is still debated. Attacks may induce in both disorders upon exposure to potential triggers in genetically susceptible individuals. Clinical phenotype manifests by temporary dysfunction of target tissue mediated by inflammation triggered by specific agents. Clinical features also change after puberty because of the partial effect of female sex hormones on the process. Appropriate definition of the syndrome and differentiating from other disorders are necessary not only for correct diagnosis, but also for planning of management strategies in children. Allergic rhinosinusitis needs to be differentiated from migraine even in experienced clinics. Questioning the presence of cranial autonomic symptoms is important clue in the differential diagnosis. Atopic disorder screening is particularly required in the diagnosis of migraine in childhood and adolescents. The link between both disorders of childhood seems to be far from a coincidence and some common inflammatory mechanisms are shared.

SUMMARY

On the basis of clinical features, laboratory findings and some practical clues in children, accurate diagnosis of migraine and atopic disorders are very critical for physicians, pediatricians and algologists.

[Differential diagnostics of headache associated with pathological changes in the nasal cavity and paranasal sinuses]

Headache is not infrequently one of the major complaints in the patients visiting the otorhinolaryngologist's office. It was estimated to occur in 24% of the patients presenting with chronic sinusitis. The cause of headache may be pathological processes either in the nasal cavity or in the paranasal sinuses as well as a primary disorder in the nervous system. The present article is concerned with the peculiar features of rhinogenic headache and that of a different etiology. It was shown that the patients suffering from headache are in need not only of the obligatory otorhinolaryngological examination including endoscopy of the nasal cavity, X-ray study and, sometimes, specialized tests but also of neurological counseling. However, the surgical treatment does not always results in the elimination or relief of the rhinogenic headache. Hence, the importance of the evaluation of the risks and benefits of such treatment for an individual patient. The formation of the contact points in the nasal mucosa is considered to be one of the possible causes of rhinogenic headache. However, this opinion needs to be confirmed by the results of large-scale comparative clinical studies.

The Role of Balloon Sinuplasty in the Treatment of Vacuum Rhinogenic Headache

In this study we tried to demonstrate how balloon sinuplasty could be an option in the treatment of the Rhinogenic Headache due to a probably disventilation of frontal sinus recess. 107 patients were included in the study with diagnosis of Rhinogenic Headache. The surgical group underwent bilateral balloon sinuplasty of the frontal sinus. The medical group underwent pharmacological treatment. Headaches characteristics were evaluated by a clinical personal diary. The severity was recorded by Visual Analog Scale 4 and 8 months after treatment. 98 out of 107 patients completed the protocol. In surgical group and in medical one the mean headache score improved at four and eight months follow up. The headache frequency attacks per month decrease from a preoperative frequency of 18 (±4 SD) in surgical group and 17 (±3 SD) in medical group to 3 (±1 SD) and 6 (±3 SD) respectively at 4 months control but increased slightly to 5 (±2 SD) and 12 (±4 SD) after 8 months. We concluded that the balloon sinuplasty should be considered as an effective alternative option after an accurate selection of surgical candidates. However, it is important a 6-8 month follow-up to evaluate the efficacy and stability of the treatment used.

Diverse Physiological Roles of Calcitonin Gene-Related Peptide in Migraine Pathology: Modulation of Neuronal-Glial-Immune Cells to Promote Peripheral and Central Sensitization

The neuropeptide calcitonin gene-related peptide (CGRP) is implicated in the underlying pathology of migraine by promoting the development of a sensitized state of primary and secondary nociceptive neurons. The ability of CGRP to initiate and maintain peripheral and central sensitization is mediated by modulation of neuronal, glial, and immune cells in the trigeminal nociceptive signaling pathway. There is accumulating evidence to support a key role of CGRP in promoting cross excitation within the trigeminal ganglion that may help to explain the high co-morbidity of migraine with rhinosinusitis and temporomandibular joint disorder. In addition, there is emerging evidence that CGRP facilitates and sustains a hyperresponsive neuronal state in migraineurs mediated by reported risk factors such as stress and anxiety. In this review, the significant role of CGRP as a modulator of the trigeminal system will be discussed to provide a better understanding of the underlying pathology associated with the migraine phenotype.

Comprehensive review on endonasal endoscopic sinus surgery

Endonasal endoscopic sinus surgery is the standard procedure for surgery of most paranasal sinus diseases. Appropriate frame conditions provided, the respective procedures are safe and successful. These prerequisites encompass appropriate technical equipment, anatomical oriented surgical technique, proper patient selection, and individually adapted extent of surgery. The range of endonasal sinus operations has dramatically increased during the last 20 years and reaches from partial uncinectomy to pansinus surgery with extended surgery of the frontal (Draf type III), maxillary (grade 3-4, medial maxillectomy, prelacrimal approach) and sphenoid sinus. In addition there are operations outside and beyond the paranasal sinuses. The development of surgical technique is still constantly evolving. This article gives a comprehensive review on the most recent state of the art in endoscopic sinus surgery according to the literature with the following aspects: principles and fundamentals, surgical techniques, indications, outcome, postoperative care, nasal packing and stents, technical equipment.

Is 'sinus' pain really sinusitis?

So-called 'sinus pain' is a common complaint in GP and ear, nose and throat clinics, and patients often receive treatment with antibiotics and decongestants. Recent evidence suggests that facial pain may not be related to the sinuses at all and that doctors may have to rethink their prescribing strategy.

What do we know about rhinogenic headache? The otolaryngologist’s challenge

Sinus headache is a common presenting complaint in the otolaryngology office. Although most patients with this presentation are found to have migraine headache, many do not, and others fail therapy. This review focuses on the current understanding of nonneoplastic rhinogenic headache: headaches that are caused or exacerbated by nasal or paranasal sinus disease or anatomy. The literature regarding this topic is reviewed, along with a review of surgical series seeking to correct these abnormalities and the outcomes obtained with intervention. Suggestions are provided regarding patient diagnosis and management, and options for intervention are reviewed.

Endoscopic management of contact point headache in patients resistant to medical treatment

The existence and the best treatment for contact point headache is a controversial issue. Therefore, this study tried to evaluate the response of the patients with a rhinogenic headache who were resistant to medical treatment to endoscopic sinus surgery. Thirty patients who suffered from a unilateral headache or facial ache for at least 1 year and resistant to medical treatment were evaluated in this research. The existence of the contact point was confirmed in CT scan and in nasal endoscopy. Moreover, a positive Lidocaine test was another important factor for selecting patients. Endoscopic surgery was the common method of surgery in patients. After 1 year, the headache and nasal obstruction were assessed according to Visual Analogue Scale (VAS) and compared to preoperative VAS. In 30 patients who entered this research, the average headache and nasal obstruction score according to VAS was 7.4 ± 1.4 and 7.9 ± 2.5, respectively. These values consequently decreased to 4.8 ± 2.3 and 3.73 ± 1.7 1 year after surgery, respectively. The overall response rate was 93.3 % and no major complications were seen in this series. If there is strong clinical suspicion and meticulous selection criteria, provided that other causes of headache have been ruled out, endoscopic management of the rhinogenic headache can be effective.

Treatment of medication overuse headache--guideline of the EFNS headache panel

BACKGROUND

  Medication overuse headache is a common condition with a population-based prevalence of more than 1-2%. Treatment is based on education, withdrawal treatment (detoxification), and prophylactic treatment. It also includes management of withdrawal headache.

AIMS

  This guideline aims to give treatment recommendations for this headache.

MATERIALS AND METHODS

  Evaluation of the scientific literature.

RESULTS

  Abrupt withdrawal or tapering down of overused medication is recommended, the type of withdrawal therapy is probably not relevant for the outcome of the patient. However, inpatient withdrawal therapy is recommended for patients overusing opioids, benzodiazepine, or barbiturates. It is further recommended to start individualized prophylactic drug treatment at the first day of withdrawal therapy or even before. The only drug with moderate evidence for the prophylactic treatment in patients with chronic migraine and medication overuse is topiramate up to 200mg. Corticosteroids (at least 60mg prednisone or prednisolone) and amitriptyline (up to 50mg) are possibly effective in the treatment of withdrawal symptoms. Patients after withdrawal therapy should be followed up regularly to prevent relapse of medication overuse.

DISCUSSION AND CONCLUSION

  Medication overuse headache can be treated according to evidence-based recommendations.

Chronic headaches and medication overuse

Chronic headaches represent a significant burden for the affected individuals and for the society, and a major challenge for successful care. Among the various types of chronic headaches, those that are associated with medication overuse (medication-overuse headache, MOH) are of particular importance because of the large proportion of patients who complain of this condition and their poor outcome. Most patients with MOH had migraine as primary headache. Practically, almost all drugs used for the symptomatic relief of migraine, including triptans and analgesics can cause MOH. Although the pathophysiology of MOH is unknown, recent studies hypothesize that plastic changes in specific pain areas of the central nervous system are main contributors to establishing MOH. Not infrequently, drug overuse is associated with habituation and failure of previously effective medications. Finally, treatment of MOH is poorly evidence based and mostly relies on clinical experience and belief.

The sinus headache explained

The concept of a sinus headache is problematic from neurology, allergology, and rhinology perspectives. It may be considered the final neurological diagnosis of exclusion when criteria for other craniofacial pain syndromes are not met. The International Headache Society definition implicates the presence of acute sinusitis, but this requirement is often not met in practice or with a patient's perception of the term. Otorhinolaryngologists have a similar exasperation with this cephalgia but tend to attribute idiopathic, nonallergic rhinopathy as the cause. Allergists often see patients who claim to have a sinus headache but instead have perennial allergic rhinitis or nonallergic rhinitis. A fresh perspective is required to determine the characteristics, differential diagnosis, and veracity of the sinus headache. We recommend using the term with caution only if the clinical picture meets the criteria for acute sinusitis-induced headache.
