Headaches due to Nasal and Paranasal Sinus Disease.

Headache and rhinosinusitis are 2 of the most common conditions seen in clinical practice. Consider sinusitis in those with new-onset headache, along with nasal congestion, maxillary tooth discomfort, anosmia, cough, or fever. Most chronic and recurring headaches, especially if migraine features are present, are not due to sinus disease, with the possible exception of rhinogenic headache due to nasal contact points. Nasal endoscopy and neuroimaging with computed tomography or MRI can confirm diagnosis and guide treatment with antibiotics, adjuvant therapies and surgery.

Successful Omalizumab Treatment of Rhinogenic Contact Point Headache Complicated by Severe Cedar Pollinosis: A Case Report.

Headache is one of the most common neurological disorders in children. The most common headache in children is a primary headache, including migraine and tension-type headache, but note that secondary headaches should be differentiated as a cause of headache in pediatric patients. The management of cedar pollinosis in pediatric patients is important because it can cause quality-of-life deficits in addition to nasal and ocular symptoms. Omalizumab, an anti-immunoglobulin E (IgE) monoclonal antibody, is approved in Japan as an add-on treatment option for severe cedar pollinosis, but few studies have investigated its real-world clinical efficacy in pediatric patients with seasonal allergic rhinitis. We report the case of a 15-year-old male patient with cedar pollinosis who suffered from uncontrolled naso-ocular symptoms, facial pain, and headache despite using histamine H1-receptor antagonists and intranasal corticosteroid spray. A sinus computed tomography scan and nasal endoscopic findings showed a swollen inferior turbinate and nasal septum in contact with the nasal cavity ipsilateral to the headache. Application of local anesthesia to the contact points within the nasal cavity resulted in the rapid relief of headaches. Therefore, we diagnosed rhinogenic contact point headache triggered by cedar pollinosis and initiated the add-on therapy of omalizumab for seasonal allergic rhinitis. Three days after the administration of omalizumab, his naso-ocular symptoms, quality-of-life deficits, and headache improved markedly, accompanied by improved nasal endoscopic findings. Omalizumab was immediately effective for the treatment of rhinogenic contact point headaches complicated by severe cedar pollinosis in a pediatric patient.

A case of uncommon anatomic variation of the middle turbinate associated with contact point headache: Bilateral double middle turbinate.

By applying pressure to nasal mucosa, anatomic variations at nasal cavity and paranasal sinuses may cause headache without any sign of inflammatory diseases such as sinusitis or nasal polyp. This phenomenon is called as contact point headache (CPH) and observed as a result of concha variations, mostly due to concha bullosa. Accessory middle turbinate (AMT) is a very rare variation and occurred as a result of mediale and inferior folding of uncinate process. When this folding is severe, AMT may cause double middle concha appearance in nasal cavity. To the extent, we know, bilateral double middle turbinate variation has not been defined before. Hereby, we present a CPH phenomenon in a patient with bilateral double middle turbinate variation which is related to contact of AMT to real middle turbinate.

Endoscopic surgical treatment for rhinogenic contact point headache: systematic review and meta-analysis.

PURPOSE: This meta-analysis study was designed to analyze endoscopic surgery's role in treating rhinogenic contact point headache. METHODS: We performed a comprehensive review of the last 20 years' English language regarding Rhinogenic contact point headache and endoscopic surgery. We included the analysis papers reporting post-operative outcomes through the Visual Analogue Scale or the Migraine Disability Assessment scale. RESULTS: We provided 18 articles for a total of 978 RCPH patients. While 777 (81.1%) subjects underwent functional nasal surgery for RCPH, 201 patients (20.9%) were medically treated. A significant decrease from the VAS score of 7.3 ± 1.5 to 2.7 ± 1.8 was recorded (p < 0.0001). At quantitative analysis on 660 patients (11 papers), surgical treatment demonstrated significantly better post-operative scores than medical (p < 0.0001). CONCLUSION: At comparison, surgical treatment in patients with rhinogenic contact points exhibited significantly better values at short-term, medium-term, and long term follow up. Endoscopic surgery should be proposed as the choice method in approaching the symptomatic patient.

Headache and rhinosinusitis: A review.

PURPOSE OF REVIEW: To explain our current understanding of headache attributed to rhinosinusitis, an often inappropriately diagnosed secondary headache. RECENT FINDINGS: Recent studies have shown that headache attributed to rhinosinusitis is often over-diagnosed in patients who actually have primary headache disorders, most commonly migraine. Failure to recognize and treat rhinosinusitis, however, can have devastating consequences. Abnormalities of the sinuses may also be treatable by surgical means, which may provide headache relief in appropriately selected patients. SUMMARY: It is important for the practicing physician to understand how rhinosinusitis fits into the differential diagnosis of headache, both to avoid overdiagnosis in patients with primary headache, and to avoid underdiagnosis in patients with serious sinus disease.

Changes in substance P levels of inferior turbinate in patients with mucosal contact headache / Alterações nos níveis da substância P da concha inferior de pacientes com cefaleiapor ponto de contato da mucosa

Abstract Introduction Mucosal contact headache is a referred pain that arises from contact between the nasal septum and the lateral nasal wall. Evidence supports the role of substance P in a contact headache such that release of substance P from sensory nerve endings causes inflammation and allergy. Objectives This study aimed to determine possible differences in substance P levels in inferior turbinate hypertrophy creating a contact headache. Methods 28 patients who had contact headaches (study group) and 16 volunteers with no complaints were included in the study. Substance P levels in the inferior turbinate tissue samples were quantified using a commercially available substance P EIA kit. Results In the study group average substance P levels were 2.65 ± 0.27 pg/mg tissue (range: 0.61-5.44) and in the control group it was 1.77 ± 0.27 pg/mg tissue (range: 0.11-4.35). The difference was statistically significant between the two groups (p = 0.0215). Average preoperative headache group visual analog scale scores was 5.93 ± 0.38 (2-9) and the turbinate volume was 6.56 ± 0.35 cm3 (3.50-10.30). The control group turbinate volume was 4.71 ± 0.39 cm3 (2.50-7.70). We found a correlation between the visual analog scale scores and substance P levels such that substance P levels were higher in visual analog scale scores above 5 (p = 0.001). Conclusion This study demonstrates the relationship between intranasal contact headaches and increased mucosal substance P levels. We also found that there is no correlation with substance P levels and volume of the inferior turbinate.

Resumo Introdução A cefaleia por ponto de contato da mucosa é uma dor direcionada que surge do contato entre o septo nasal e a parede nasal lateral. Evidências corroboram o papel da substância P na cefaleia de contato, de tal forma que a liberação da mesma a partir de terminações nervosas sensoriais possa causar inflamação e alergia. Objetivo Determinar possíveis diferenças nos níveis da substância P na hipertrofia de conchas inferiores em relação à cefaleia de contato. Método Foram incluídos no estudo 28 pacientes que apresentaram cefaleia por ponto de contato (Grupo Estudo) e 16 voluntários sem queixas. Os níveis de substância P nas amostras de tecido da concha inferior foram quantificados com um kit substância P EIA, comercialmente disponível. Resultados No grupo do estudo, os níveis médios de substância P foram 2,65 ± 0,27 pg/mg de tecido (variação: 0,61-5,44) e no grupo controle foram de 1,77 ± 0,27 pg/mg de tecido (variação: 0,11-4,35) e a diferença foi estatisticamente significante entre os dois grupos (p = 0,0215). O escore médio da escala visual analógica do grupo de cefaleia pré-operatória foi de 5,93 ± 0,38 (2-9) e o volume das conchas foi de 6,56 ± 0,35 cm3 (3,50-10,30). O volume da concha do grupo controle foi de 4,71 ± 0,39 cm3 (2,50 ± 7,70). Encontramos uma correlação entre o escore da escala visual analógica e os níveis de substância P, de modo que os níveis de substância P foram maiores nos escores da escala visual analógica acima de 5 (p = 0,001). Conclusão Este estudo demonstra a relação entre cefaleias por contato intranasais e níveis aumentados de substância P nas mucosas. Também observamos que não há correlação com os níveis de substância P e o volume da concha inferior.

Rhinogenic Headache in Children and Adolescents.

PURPOSE OF REVIEW: The purpose of this review is to evaluate and explain our current understanding of rhinogenic headache in the pediatric population. RECENT FINDINGS: One study showed that 40 % of pediatric patients with migraine had previously received an incorrect diagnosis of sinus headache. Two studies found that over 50% of pediatric patients with migraines have associated cranial autonomic symptoms, possibly elucidating the reasons for misdiagnosis. Some case reports demonstrate successful treatment of rhinogenic contact point headache with the surgical resection of mucosal contact points, although this diagnosis continues to be debated. Many pediatric patients diagnosed with a sinus-related headache actually meet criteria for primary headache disorders. Primary headache disorders should be considered in pediatric patients with headache and associated rhinologic symptoms. Some literature suggests that mucosal contact point headaches can be surgically treated in children, but the level of evidence is inadequate, and additional robust trials are needed.

Rhinogenic headache in pediatric and adolescent patients: an evidence-based review.

BACKGROUND: Although some causes of rhinogenic headache, such as acute sinusitis, have clear diagnostic criteria, others, such as "sinus headache" and mucosal contact points, are more nebulous. Misdiagnosis of these entities and primary headaches may result in unnecessary medical or surgical treatment. The purpose of this systematic review is to delineate current understanding of diagnosis and treatment of rhinogenic headaches, including sinus and mucosal contact point headaches, in children. METHODS: PubMed, SCOPUS, and the Cochrane databases were searched for studies on sinus headache and mucosal contact point headaches in children. Studies were assessed for level of evidence, and risk of bias was assessed by Methodological Index for Non-Randomized Studies (MINORS) scoring. Diagnostic criteria, management strategies, and other clinical data were analyzed. RESULTS: Eight studies met the inclusion criteria. Level of evidence was predominantly 4. Forty percent of pediatric patients with migraine had been previously misdiagnosed with sinus headache. Of 327 pediatric patients in two studies, between 55% and 73% had at least 1 cranial autonomic symptom associated with their migraine. For children with mucosal contact point headaches, surgical management in select patients improved headache intensity or severity in 17 (89%) cases. CONCLUSION: The majority of pediatric patients with sinus headache harbor a primary headache disorder, with migraine being most common. Physicians should suspect primary headache disorders in pediatric patients with chronic headaches and a normal exam. Although some case series are supportive of surgical management for mucosal contact point headaches in children, the level of evidence supporting these recommendations is insufficient. High-quality clinical trials are necessary for continuing to improve outcomes in patients with these clinical entities.

Imaging for headache: what the otolaryngologist looks for.

Diagnosing a rhinogenic cause of headache or facial pain outside of the classic definitions of chronic, acute, and subacute sinusitis can be challenging for the practicing otolaryngologist. Contact-point headaches have been clinically characterized as causing facial pain secondary to abutting mucosal contact from the lateral nasal wall to the septum. Imaging landmarks may help identify these potential contact points radiographically through revealing anatomic variants such as septal spurs and abnormally large lateral nasal structures. However, other potential rhinologic sources, such as barosinusitis, recurrent barotrauma, or recurrent acute sinusitis occurring between active episodes, are challenging to identify through hallmark imaging findings.

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.

Headaches caused by nasal and paranasal sinus disease.

Headache and rhinosinusitis are 2 of the most common conditions seen in clinical practice. In general, chronic and disabling headaches, especially if migraine features are present, are not due to sinus abnormalities. In suspected cases of bacterial sinusitis, computed tomography and magnetic resonance imaging are both effective in demonstrating the infection. Although most cases of sinusitis are fairly easy to diagnose, sphenoid sinusitis may be overlooked, and can present with progressive or thunderclap headache in adults. Contact-point headache should be considered in patients with focal headaches and a contact point on the lateral nasal wall.

A critical evaluation of migraine trigger site deactivation surgery.

Migraine headache trigger site deactivation surgery is a term that encompasses 4 different surgical procedures that are performed based on headache onset location for the preventative treatment of migraine headaches. Multiple studies have demonstrated some efficacy of these procedures, but closer evaluation of the methodology of these studies reveals major flaws in study design. In this article, the author provides an overview of the procedures and presurgical screening tools, as well as a critical evaluation of 2 of the major studies that have been published. In addition, the author provides his opinion on future study designs that may help to better determine the potential efficacy of these experimental procedures and potential headache subtypes (contact point headache, supraorbital neuralgia, and occipital neuralgia) that may respond to peripheral decompression surgery.

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.
