Other Secondary Headaches: Odontogenic Pain and Other Painful Orofacial Conditions.

This article discusses extremely common odontogenic pain conditions, which may occasionally present to the neurology clinic mimicking headache, and other uncommon orofacial pain conditions, which may do the same. Typical presentations, investigative strategies, and management are discussed, as well as highlighting key diagnostic criteria and the importance of involving oral or dental specialists where diagnostic uncertainty exists.

Could painful temporomandibular disorders be nociplastic in nature? A critical review and new proposal.

Classification of temporomandibular disorders (TMD) and, indeed, all types of orofacial pains has significantly progressed in the last decade based on international consensus work and operationalized clustering of signs and symptoms. A challenging gap nevertheless continues to exist in terms of understanding the underlying pain mechanisms and link to management. Recently, a novel mechanistic descriptor 'nociplastic pain' was introduced, and diagnostic algorithms and characteristic features were proposed. This narrative and critical review aim to discuss to what extent could painful TMD conditions fit into this category. Moreover, a number of less common types of orofacial pain could possibly also reflect nociplastic pain mechanisms. A model to differentiate TMD pain mechanisms is proposed, and the implications for management are discussed. The purpose of this review is to stimulate original and novel research into mechanisms of orofacial pain and hopefully thereby improve management of the individual patient.

Development of the 12-Item Facial Complaints Evaluation Scale (FaCES-12).

OBJECTIVES: Chronic rhinosinusitis and related rhinologic disorders are common in routine otolaryngologic practice. Common presenting symptoms include nasal obstruction, facial pain, facial pressure, headache, and a subjective feeling of the face feeling "swollen," a perceptual distortion. No validated scale exists to assess facial pain in addition to perceptual distortion or headache. The objective was to develop a novel scale for assessment of facial symptoms experienced by patients presenting for rhinologic evaluation. METHODS: This was a prospective validation cross-sectional study. A patient questionnaire, the 12-item Facial Complaints Evaluation Scale (FaCES-12), was created to evaluate facial symptoms based on clinical experience and the literature, including severity and timing of facial pain, facial pressure, facial perceptual swelling, and headache. Each item was assessed utilizing an 11-point Likert scale ranging from 0 to 10 in severity. Data was collected prospectively from 210 patients in 1 private and 2 academic otolaryngologic practices from August to December 2019 along with the PROMIS Pain Intensity Scale 3a and 22-Item Sino-nasal Outcome Test. Construct validity was determined using Pearson correlation and exploratory factor analysis. Internal consistency and test-retest reliability were assessed by calculating Cronbach's alpha and assessing test-retest scores. RESULTS: A new 12-item scale named FaCES-12 was developed. FaCES-12 demonstrated high reliability with a Cronbach's alpha of .94 and high test-retest reliability (r = .90). The scale revealed very strong correlation with the PROMIS Pain Intensity Scale 3a (r = .81) and moderate correlation with the Sino-nasal Outcome Test (r = .48). Exploratory factor analysis demonstrated the scale contained interrelated variables that measured unique components of facial sensations. CONCLUSION: The FaCES-12 is a valid and reliable instrument for use in the evaluation of facial symptoms. Further research into the application of this scale is warranted.

Pregnancy related factors and temporomandibular disorders evaluated through the diagnostic criteria for temporomandibular disorders (DC/TMD) axis II: a cross sectional study.

INTRODUCTION: Temporomandibular disorder (TMD) is a multifaceted condition impacting the chewing system, with its frequency varying across different age groups and showing a higher incidence in women. The involvement of estrogen in TMD has been examined due to the presence of estrogen receptors in the TMJ area. However, the exact effect of estrogen on TMD is complex. During pregnancy, marked by significant hormonal fluctuations, the impact on TMD has been hypothesized but remains unclear due to inconsistent results from various studies. METHODS: In this cross-sectional study, we enrolled 32 pregnant women consecutively. We gathered information on demographics, TMD evaluations (using the Graded Chronic Pain Scale, Jaw Functional Limitation Scale-20, and Oral Behaviors Checklist), and mental health assessments (including Patient Health Questionnaire-9, Patient Health Questionnaire-15, and Generalized Anxiety Disorder-7). We employed descriptive statistics to summarize continuous and categorical data and used t-tests and chi-square tests for comparisons. We also conducted multivariate linear regression, adjusted for demographic factors, to investigate correlations. RESULTS: The study group mainly consisted of women aged 30-35 (40.6%) and 25-30 (18.8%). Most participants had completed high school (50%) and were married (71.9%). A notable association was found between younger women (under 30) and higher levels of somatic symptoms (p = 0.008) and generalized anxiety (p = 0.015). Women in their second trimester showed lower severity of somatic symptoms (p = 0.04). A significant link was also observed between depression severity and somatic symptom severity (p = 0.01). However, we found no significant correlations with other TMD-related health aspects. DISCUSSION: Our study identified significant associations between psychosomatic and psychological symptoms with variables like age and pregnancy trimester in pregnant women. However, it notably failed to establish a clear relationship between pregnancy-related factors and the severity of temporomandibular disorders (TMD). More comprehensive studies with larger participant pools are necessary to further validate and expand these findings.

[Specificities of orofacial neuropathic pain]. / Spécificités de la douleur neuropathique oro-faciale.

Head pain and notably orofacial pain differs from spinal pain on pathophysiological, clinical, therapeutic and prognostic levels. Its high prevalence, important impact on quality of life and significant socio-economical burden justify specific study of such type of pain. Among them, neuropathic orofacial pain resulting from disease or trauma of the trigeminal nervous system is among the most difficult types of pain to diagnose and to treat. Deciphering of underlying peripheral and central mechanisms has allowed numerous conceptual, clinical and therapeutic advances, notably the role of neural and non neural cell types, such as glia, immunocytes, vascular endothelial cells or the role of trigeminal sensory complex neural circuitry reconfiguration in the development of post-traumatic trigeminal neuropathic pain. Cellular interactions within the trigeminal ganglion, allowing a better understanding of several painful dental, ocular or cephalalgic comorbidities, are also described.

Title: Spécificités de la douleur neuropathique oro-faciale. Abstract: Les douleurs de la région céphalique ­ et notamment les douleurs oro-faciales ­ diffèrent des douleurs spinales sur les plans physiopathologique, clinique, thérapeutique et pronostique. Leur prévalence élevée, leur fort retentissement sur la qualité de vie individuelle et leur impact économique et sociétal important justifient une étude spécifique. Parmi ces douleurs, les douleurs neuropathiques, résultant d'une maladie ou d'un traumatisme du système nerveux trigéminal, sont parmi les plus difficiles à diagnostiquer et à soigner. L'étude des mécanismes neurobiologiques, périphériques et centraux les sous-tendant a permis de nombreuses avancées conceptuelles, cliniques et thérapeutiques, avec, par exemple, la mise en évidence du rôle des cellules nerveuses et non nerveuses, telles que la glie, les immunocytes, les cellules endothéliales vasculaires ou le rôle de la reconfiguration de la circuiterie nerveuse au niveau du complexe sensitif trigéminal, dans la genèse des douleurs neuropathiques post-lésionnelles. Les interactions cellulaires au sein du ganglion trigéminal, susceptibles d'éclairer la compréhension de certaines comorbidités douloureuses dentaires, oculaires ou céphalalgiques, sont également décrites.

Diagnostic Accuracy of a Temporomandibular Disorder Pain Screener in Patients Seeking Endodontic Treatment for Tooth Pain.

INTRODUCTION: This study assessed the accuracy of a TMD Pain Screener questionnaire in identifying patients with temporomandibular disorder (TMD) pain among those seeking endodontic treatment for tooth pain. It also investigated whether the screener accuracy could be improved by adding questions regarding putative predictors of TMD status. METHODS: One hundred patients seeking endodontic treatment for tooth pain were enrolled. Participants completed the 6-question TMD Pain Screener before treatment. A board-certified orofacial pain specialist/endodontic resident conducted endodontic and TMD examinations using validated Diagnostic Criteria for TMD (DC/TMD). The sensitivity (Se), specificity (Sp), and positive/negative predictive values (PPVs/NPVs) were calculated for the 6-question and 3-question versions of the TMD Pain Screener. Logistic regression and receiver operating characteristic curve (AUROC) analyses were performed to determine the screening accuracy. RESULTS: At the screening threshold of ≥3, TMD Pain Screener's sensitivity was 0.85, specificity 0.52, PPV 0.68, and NPV 0.75 for the 6-question version and 0.64, 0.65, 0.69, and 0.61, respectively, for the 3-question version. The AUROC was 0.71 (95% CL: 0.61, 0.82) and 0.60 (95% CL: 0.48, 0.71) for full and short versions, respectively. Adding a rating of current pain intensity of the chief complaint to the screener improved the AUROC to 0.81 (95% CL: 0.72, 0.89) and 0.77 (95% CL: 0.67, 0.86) for full and short versions, respectively, signifying useful overall accuracy. CONCLUSIONS: The 6-question TMD Pain Screener, combined with the patient's rating of current pain intensity of the chief complaint, could be recommended for use in endodontic patients with tooth pain for detecting painful TMD.

Self-reported bruxism in patients with post-traumatic stress disorder.

OBJECTIVE: The present study aimed to investigate the association between self-reported awake/sleep bruxism, and orofacial pain with post-traumatic stress disorder (PTSD). METHODS: A case-control study with a convenience sample was designed. Participants were recruited from a university-based Trauma Ambulatory. The diagnosis of PTSD was established through a clinical interview and the Structured Clinical Interview (SCID-I/P). Thirty-eight PTSD patients and 38 controls completed the Research Diagnostic Criteria for Temporomandibular Disorders Axis-II to categorize awake/sleep bruxism and orofacial pain. Following this, we performed a short clinical examination of the temporomandibular joint and extraoral muscles. RESULTS: Adjusted logistic regression analysis showed that awake bruxism was associated with PTSD (OR = 3.38, 95% CI = 1.01-11.27, p = 0.047). Sleep bruxism was not associated with any covariate included in the model. In a Poisson regression model, PTSD (IRR = 3.01, 95% CI = 1.38-6.55, p = 0.005) and the muscle pain/discomfort (IRR = 5.12, 95% CI = 2.80-9.36, p < 0.001) were significant predictors for current orofacial pain. CONCLUSIONS: PTSD was associated with self-reported awake bruxism and low-intensity orofacial pain. These conditions were frequent outcomes in patients previously exposed to traumatic events. CLINICAL RELEVANCE: We suggest including a two-question screening for bruxism in psychiatry/psychology interviews to improve under-identification and to prevent harmful consequences at the orofacial level.

Pharmacological therapy in the management of temporomandibular disorders and orofacial pain: a systematic review and meta-analysis.

BACKGROUND: Temporomandibular disorders (TMD) are manifested by soreness in the jaw joint area and jaw muscles, clicks or creaks when opening or closing the mouth. All these symptoms can be disabling and occur during chewing and when the patient yawns or speaks. Several classes of drugs are used to treat symptoms. This review aims to assess which drug suits the different signs. METHODS: Pubmed, Web of Science and Lilacs were systematically searched until 01/02/2023. Clinical trials were selected that dealt with drugs used in temporomandibular dysfunction RESULTS: Out of 830 papers, eight studies were included. The Meta-Analysis with Continuous Outcomes with Pre-Calculated Effect Sizes resulted in the rejection that there is intergroup variability (p.0.74). CONCLUSIONS: Treatment of orofacial pain is still a significant challenge for dentistry. We can conclude that there is no drug of first choice in the treatment of temporomandibular pain. However, the clinician must distinguish the type of pain and the aetioloic cause of the pain so that the patient can be treated and managed pharmacologically.

Comparison of force profiles from two musculoskeletal palpation methods: A methodological study.

BACKGROUND: The Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) protocol recommends a 5 s and 1 kg force dynamic palpation around the lateral condylar pole of the temporomandibular joint. However, the accuracy and precision of the generated force are not known. OBJECTIVE: To assess and compare the force profiles generated from dynamic palpation manually and using a palpometer, based on the forces and time recommendations suggested by the DC/TMD protocol. METHODS: Nineteen healthy adults applied forces of 0.5 kg, 1.0 kg and 2.0 kg on a calibrated force sensor in a circular motion within target times of 2 s and 5 s. Participants used their right index finger for manual palpation and a calibrated palpometer for device-assisted palpation. Ten repetitions of each target force at both target times were applied. Time taken to complete each application was recorded. Repeated measures analysis of variance was used for analysis of accuracy measured as the relative difference between targeted force and actual force values and precision measured as the coefficient of variation (CV) within the 10 repeated measurements. RESULTS: Accuracy was significantly lower (better) and precision higher (lower CV) with the palpometer than with manual palpation (p < .001). There were significant differences in accuracy and precision between the different forces but not palpation times. Most participants could not achieve the target times and tended to be faster, irrespective of the palpation method (p > .063). CONCLUSION: A palpometer is a more accurate and precise palpation method for dynamic force assessment compared to manual palpation; however, it remains difficult to standardize the palpation duration.

Predictors of Non-Rhinogenic Facial Pain or Pressure in Otolaryngology Clinic.

OBJECTIVES: Identify demographic and clinical characteristics that may help differentiate non-rhinogenic facial pain or pressure (NRFP) from sinusitis. STUDY DESIGN: Retrospective single-institution study. SETTING: Tertiary Care Center Rhinology Clinic. METHODS: All patients presenting with a complaint of facial pain or pressure over a 3-year period were included. Patients were categorized into either NRFP or sinusitis groups based on computed tomography imaging and nasal endoscopy. Data pertaining to demographics, history, and SNOT-22 questionnaire domains were compared via univariate analysis as well as logistic regression with backwards variable selection. RESULTS: A total of 296 patients met inclusion criteria, of which 128 had NRFP and 168 had sinusitis. A significantly greater percentage of patients in the NRFP group were women of childbearing age (40.6% vs 28.0%, P = .02). Backwards variable selection resulted in a model with four variables predicting a diagnosis of NRFP-female sex (odds ratio [OR] = 2.998, P < .0001), no history of prior sinonasal surgery (OR = 0.340 for history vs no history, P < .01), low nasal domain score (OR = 0.551, P < .0001), and high ear/facial domain score (OR = 1.453, P < .01). CONCLUSION: Accurately identifying patients with NRFP at initial presentation based on history would help direct patients to the appropriate care pathway and prevent ineffective treatments such as antibiotics and sinus procedures. Our findings suggest that the suspicion for NRFP should be higher in women of child-bearing age as well as patients with greater ear/facial symptoms or lesser nasal symptoms.

Chronic temporomandibular disorder pain patients with a history of neuropathic pain treatment: a narrative research on their diagnosis and treatment history.

The aims of this qualitative research were (1) to gain more insight in the diagnostic and treatment history of patients with chronic temporomandibular disorder (TMD) pain; (2) to get a deeper understanding of possible factors that are involved in the possible delay in setting a TMD-pain diagnosis and receiving appropriate treatment; and (3) to get a deeper understanding of the perspectives and experiences of chronic TMD-pain patients on the possible improvement of various aspects of their diagnostic and treatment journey.MethodsIn this narrative research, semi-structured interviews took place with patients who experienced chronic orofacial pain (OFP) for at least three years before getting diagnosed with, and treated for, TMD pain by an OFP specialist in an interprofessional setting.ResultsIn total, ten patients were interviewed in-depth. Patients experienced their chronic OFP in different ways, but all reported a significant impact of their pain on their quality of life. All patients visited numerous health care professionals before their TMD diagnosis was set. Among others, they underwent anti-neuropathic pain medication therapies and invasive surgeries, which did not significantly reduce their chronic OFP. The interprofessional TMD-pain treatment reduced the suffering of the chronic OFP substantially, also 6 months after the start of therapy, and improved the quality of life for all patients. In most of them, the OFP intensity was also decreased.ConclusionChronic TMD-pain patients with a history of neuropathic pain treatment may experience a long journey until receiving the appropriate diagnosis and treatment. This stresses the need to improve the implementation of chronic TMD-pain guidelines.

The midfacial segment pain: little known disorder in need of scientific evaluation.

Despite its inclusion in the International Classification of Orofacial Pain, tension-type orofacial pain has little support in the scientific literature. However, a similar-in-phenotype orofacial pain perceived in the middle segment of the face has been described by few case series from mostly ear, nose and throat clinics. The authors of these descriptions used the term 'midfacial segment pain'. Patients had no significant sinonasal disorder in these studies, but experienced symmetrical pain perceived mostly over the maxillary and ethmoid sinuses. No aura or autonomic symptoms were present apart from mild nasal congestion or rhinorrhoea in some individuals. This description appears similar to tension-type headache, but with midfacial location. In this viewpoint, we indicate a need to fill this gap in scientific knowledge and propose a multicentre interdisciplinary study that would give a detailed description of this type of orofacial pain.

Effects of physical activity levels on characteristic pain in temporomandibular dysfunctions: a cross-sectional study.

BACKGROUND: Physical activity is known to influence the symptoms of a variety of pain disorders including fibromyalgia and osteoarthritis although the underlying mechanism is not fully understood. In spite of the high prevalence of temporomandibular disorders (TMD), no previous study has objectively evaluated the relationship between TMD and general physical activity. This study aims to investigate the influence of physical activity on pain and disability from TMD, considering various confounders including sleep, systemic inflammation, psychosocial disturbances, and widespread pain. METHODS: This observational cross-sectional study is based on consecutive samples of 100 TMD patients (22 with high pain disability and 78 with low pain disability level). Physical activity levels were assessed with actigraph. Level of pain and disability were evaluated using the Graded Chronic Pain Scale. Hematologic examinations including inflammatory biomarkers were assessed and comorbidities were investigated with validated questionnaires. Differences were analyzed according to disability level. RESULTS: Patients with high disability level spent significantly more time doing both moderate (p = 0.033) and vigorous (p = 0.039) level physical activity. Light physical activity, on the other hand, was associated with low disability but the difference did not reach statistical significance. Time spent in light physical activity was significantly associated with high levels of pain and disability (p = 0.026, ß = -0.001) and time spent in vigorous physical activity had significant predictive power (cutoff value 2.5 min per week, AUC 0.643, p = 0.041). Scores of the Jaw Function Limitation Score-20 (p = 0.001), present McGill Pain Score (p = 0.010), and number of people potentially diagnosed with fibromyalgia (p = 0.033) were significantly higher in the high disability group. CONCLUSIONS: Moderate or vigorous physical activity is associated with worse TMD symptoms while light physical activity may be beneficial. Further research related to the amount and frequency of physical activity is necessary to establish clinical guidelines for TMD. TRIAL REGISTRATION: clinical trial registration of the Clinical Research Information Service of Republic of Korea (number KCT0007107).

Knowledge and experience of dentists with patients with trigeminal neuralgia: A prospective, cross-sectional survey study.

OBJECTIVE: Trigeminal neuralgia (TN) and orofacial pain (OFP) patients frequently refer to dentists. It is often confused with odontogenic pain and dental procedures are performed. In this study, the authors aimed to reveal the knowledge and experience of dentists about TN. METHODS: This is a cross-sectional study that includes dentists who participate in volunteering via an online questionnaire. The questionnaire form contains demographic data, TN treatment, and diagnosis consisting of 18 questions. RESULTS: The data of 229 dentists were examined. Almost 82% of the participants reportedly knew the diagnostic criteria of TN and 61.6% reported that they had previously referred patients with TN. The most frequently confused diagnosis was odontogenic pains (45.9%). CONCLUSION: TN diagnostic criteria should be included more often in the education of dentists. Thus, it is possible to prevent unnecessary dental procedures. There is a need to increase knowledge on this subject with further studies involving dental students.

The Adaptive, Pain Sensitive, and Global Symptoms Clusters: Evidence from a Patient-Based Study.

OBJECTIVES: The largest epidemiologic study conducted about painful temporomandibular disorders (pTMDs) to date identified 3 clusters of individuals with similar symptoms-adaptive, pain sensitive, and global symptoms-which hold promise as a means of personalizing pain care. Our goal was to compare the clinical and psychological characteristics that are consistent with a pTMD clinical examination among patients who are seeking care and assigned to the different clusters. METHODS: This cross-sectional study used data from the medical records of patients attending Duke Innovative Pain Therapies between August 2017 and April 2021 who received a pTMD diagnosis (i.e., myalgia) and consented to have their data used for research. Data included orofacial and pain-related measures, dental features, and psychological measures. We used the Rapid OPPERA Algorithm to assign clusters to patients and multinomial regression to determine the likelihood (odds ratios [OR] and 95% confidence intervals [CI]) of being assigned to the pain sensitive or global symptoms cluster attributed to each measure. RESULTS: In total, 131 patients were included in this study and assigned a cluster: adaptive (n = 54, 41.2%), pain sensitive (n = 49, 37.4%), and global symptoms (n = 28, 21.4%). The PS cluster displayed greater numbers of temporomandibular joint sites (OR, 1.29; 95% CI, 1.01 to 1.65) and masticatory (1.48; 1.19 to 1.83) and cervical (1.23; 1.09 to 1.39) muscles with pain evoked by palpation. The GS cluster displayed greater scores of pain catastrophizing (1.04; 1.01 to 1.06) and perceived stress (1.23; 1.03 to 1.46) and was more likely to report persistent pain (16.23; 1.92 to 137.1) of higher impact (1.43; 1.14 to 1.80). CONCLUSION: Our findings support that care-seeking patients with pTMDs who are assigned to the GS cluster display a poorer psychological profile, even though those assigned to the PS cluster display more measures consistent with orofacial pain. Findings also establish the PS cluster as a group that does not display psychological comorbidities despite being hypersensitive. KNOWLEDGE TRANSFER STATEMENT: This study informs clinicians that patients seeking care for painful temporomandibular disorders, in specific cases of myalgia, can be classified into 1 of 3 groups that display unique profiles of symptoms. Most importantly, it emphasizes the importance of examining patients with painful temporomandibular disorders in a holistic manner that includes assessing symptoms of psychological distress. Patients with greater psychological distress will likely benefit from multidisciplinary treatment strategies that may include psychological treatments.

Lymphoma masquerading as jaw pain, headache, and syncope: A case report.

BACKGROUND: Lymphomas of parapharyngeal space often have complex manifestations, posing a diagnostic dilemma for clinicians. CASE DESCRIPTION: A 64-year-old man sought treatment for a 4-month history of unresolving right-sided headache and jaw pain associated with syncope, all of which started with a toothache. Since the onset of pain, the patient had undergone multiple diagnostic tests with various specialists, with no pain relief. A detailed clinical and radiologic examination by an orofacial pain specialist revealed diffuse large B-cell lymphoma in the parapharynx. PRACTICAL IMPLICATIONS: A thorough knowledge of the head and neck anatomy helps in identifying the pathophysiology of complex orofacial pain manifestations, which assists in early diagnosis and treatment.

Predictors of patients' satisfaction after temporomandibular disorder treatment in a referral clinic.

BACKGROUND: Evaluating patients' satisfaction after received care for temporomandibular disorders (TMD) pain provides oral health care professionals with knowledge and tools to improve their clinical procedures. However, knowledge on patient characteristics that determine satisfaction with the received care for TMD pain is lacking. OBJECTIVE: To identify potential baseline predictors for patients' satisfaction regarding the management of TMD pain upon treatment completion in a referral clinic. METHODS: Eligible patients, viz., individuals of ≥16 years of age, with a TMD-pain diagnosis according the diagnostic criteria for TMD (DC/TMD), and who were treated in a referral clinic, were included. As part of their standard care, a set of diagnostic questionnaires was filled in (e.g. TMD-pain screener, graded chronic pain scale (GCPS), etc.). After completion of the received care, patients filled in a custom-made questionnaire based on patient reported experience measures (PREMs) to quantify their satisfaction with their treatment results and received care. To identify potential predictors associated with patients' satisfaction, univariate and multivariate linear regression analyses were used. RESULTS: Twenty-seven patients (mean 39.6, SD 15.0) were included in this study. Overall, the patients were satisfied with the treatment results and the received care. Depressive feelings were negatively associated with satisfaction of treatment results (p = .01) and positively associated with satisfaction of received care (p = .01), while pain intensity was negatively associated with satisfaction of the received care. CONCLUSION: Depressive feelings are a significant negative predictor of patients' satisfaction with the treatment result for TMD pain, while average pain intensity is a significant negative predictor of patients' satisfaction with the received care.

A rare case of vestibular schwannoma manifesting as trigeminal neuralgia.

BACKGROUND: In this case report, the authors reviewed a rare case of a vestibular schwannoma manifesting as trigeminal neuralgia (TN). Intracranial tumors can have a variety of orofacial pain symptoms. Among benign cerebellopontine angle tumors, vestibular schwannoma is the most common cause of a TN-like manifestation. Although the most common symptoms of a vestibular schwannoma are hearing loss and vestibulopathy, the unique feature of this case was the manifestation of symptoms consistent with TN. CASE DESCRIPTION: The patient had right-sided episodic facial pain that was short in duration and severe in intensity. The initial differential diagnoses included short-lasting, unilateral, neuralgiform headache attacks with conjunctival injection and tearing and TN. As part of the routine evaluation, the patient was referred for brain magnetic resonance imaging, which revealed a right-sided vestibular schwannoma. The patient was prescribed 200 mg of gabapentin 3 times daily and was referred to neurosurgery for excision of the schwannoma. Surgical excision resulted in complete resolution of pain. PRACTICAL IMPLICATIONS: This case illustrates the importance of interdisciplinary treatment and how it can lead to an optimal outcome for a patient with complex orofacial pain symptoms.

Orofacial Pain and Risk of Dysphagia in Women With Fibromyalgia: A Cross-Sectional Observational Study.

OBJECTIVE: This study aims to analyze the frequency of dysphagia risk and swallowing-associated quality of life (QoL) in a sample of women with fibromyalgia syndrome (FMS) and examine the potential relationship between risk of dysphagia and chronic orofacial pain (COP) in a sample of women with FMS. METHOD: A cross-sectional observational study was conducted in 46 women with FMS. COP was assessed by mouth opening, the orofacial visual analog scale (VAS), and the craniofacial pain and disability inventory (CF-PDI). Risk of dysphagia was assessed using the Eating Assessment Tool (EAT-10) and the volume-viscosity swallowing test (V-VST). Swallowing-associated QoL was determined using the Swallowing Quality of Life (SWAL-QOL) questionnaire. RESULTS: Thirty patients were identified as being at risk for dysphagia (65.21%) using the EAT-10 and, according to the SWAL-QOL, 41.30% of patients had alterations in QoL associated with swallowing. The EAT-10 correlated positively with orofacial VAS, CF-PDI-total, CF-PDI-pain and disability, and CF-PDI-jaw-functional status. In relation to SWAL-QOL, negative correlations were observed for orofacial VAS, CF-PDI-total, CF-PDI-pain and disability, and CF-PDI-jaw-functional status. Patients at risk of dysphagia (EAT-10 and V-VST) had significantly higher scores in orofacial VAS (p = .002 and p = .015), CF-PDI-total (p = .006 and p = .014), and CF-PDI-pain and disability (p = .004 and p = .013). CONCLUSIONS: In this sample of women with FMS, we identified a high rate of dysphagia risk. Also, a high percentage of these women presented alterations in QoL associated with swallowing. Patients at risk for dysphagia had significantly higher orofacial VAS and CF-PDI-total scores, supporting the relationship between dysphagia risk and COP in FMS. Further research to establish the need for appropriate assessment referrals in clinical practice to determine whether dysphagia is present in this population is needed.

Debilitating lower back pain during menses unexpectedly resolved after treatment of subclinical temporomandibular disorder: a case report.

This case report describes a patient in whom debilitating lower back pain that always occurred during menses resolved when she received treatment for subclinical temporomandibular disorder (TMD). The patient was diagnosed with subclinical TMD and facial myalgia based on the results of clinical and radiographic examinations. She was treated with maxillary (nighttime) and mandibular (daytime) dental orthotics to provide stabilization and decompression of the temporomandibular joints. After 12 weeks of appliance therapy, which resulted in resolution of the TMD symptoms, the patient reported that the debilitating lower back pain she experienced during menses had ceased. Her back pain did not return after the use of the mandibular appliance was discontinued. The authors discuss how neurologic, postural, inflammatory, and qi flow changes attributed to the patient's TMD treatment may have contributed to the cessation of the patient's menses-related lower back pain.
