Grading the intensity of nondental orofacial pain: Identification of cutoff points for mild, moderate, and severe pain
Background: When assessing pain in clinical practice, clinicians often label pain as mild, moderate, and severe. However, these categories are not distinctly defined, and are often used arbitrarily. Instruments for pain assessment use more sophisticated scales, such as a 0â10 numerical rating scale, and apart from pain intensity assess pain-related interference and disability. The aim of the study was to identify cutoff points for mild, moderate, and severe nondental orofacial pain using a numerical rating scale, a pain-related interference scale, and a disability measurement. Materials and methods: A total of 245 patients referred to the Facial Pain Unit in London were included in the study. Intensity and pain-related interference were assessed by the Brief Pain Inventory. Pain-related disability was assessed by the Chronic Graded Pain Scale. Average pain intensity (0â10) was classified into nine schemes with varying cutoff points of mild, moderate, and severe pain. The scheme with the most significant intergroup difference, expressed by multivariate analysis of variance, provided the cutoffs between mild, moderate, and severe pain. Results: The combination that showed the greatest intergroup differences for all patients was scheme 47 (mild 1â4, moderate 5â7, severe 8â10). The same combination provided the greatest intergroup differences in subgroups of patients with temporomandibular disorder and chronic idiopathic facial pain, respectively. Among the trigeminal neuralgia patients alone, the combination with the highest intergroup differences was scheme 48 (mild 1â4, moderate 5â8, severe 9â10). Conclusion: The cutoff points established in this study can discriminate in pain intensity categories reasonably well, and showed a significant difference in most of the outcome measures used
Diagnosis and management of trigeminal neuropathic pains
Trigeminal neuropathic pains have presented diagnostic and therapeutic challenges to providers. In addition, knowledge of pathophysiology, current classification systems, taxonomy and phenotyping of these conditions are incomplete. While trigeminal neuralgia is the most identifiable and studied, other conditions are being recognized and require distinct management approaches. Furthermore, other facial pain conditions such as atypical odontalgia and burning mouth syndrome are now considered to have neuropathic elements in their etiology. This article reviews current knowledge on the pathophysiology, diagnosis and management of neuropathic pain conditions involving the trigeminal nerve, to include: trigeminal neuralgia, trigeminal neuropathic pain (with traumatically induced neuralgia and atypical odontalgia) and burning mouth syndrome. Treatment modalities are reviewed based on current and best available evidence. Trigeminal neuralgia is managed with anticonvulsant drugs as the first line, with surgical options providing variable results. Trigeminal neuropathic pain is managed medically based on the guidelines for other neuropathic pain conditions. Burning mouth syndrome is also treated with a number of neuropathic medications, both topical and systemic. In all these conditions, patients need to be thoroughly educated about their condition, involved in its management, and be provided with supportive and adjunctive treatment resources
History of facial pain diagnosis
PREMISE: Facial pain refers to a heterogeneous group of clinically and etiologically different conditions with the common clinical feature of pain in the facial area. Among these conditions, trigeminal neuralgia (TN), persistent idiopathic facial pain, temporomandibular joint pain, and trigeminal autonomic cephalalgias (TAC) are the most well described conditions.
CONCLUSION: TN has been known for centuries, and is recognised by its characteristic and almost pathognomonic clinical features. The other facial pain conditions are less well defined, and over the years there has been confusion about their classification
Impact of pain and postoperative complications on patient-reported outcome measures 5Â years after microvascular decompression or partial sensory rhizotomy for trigeminal neuralgia
BACKGROUND: Microvascular decompression (MVD) and partial sensory rhizotomy (PSR) provide longstanding pain relief in trigeminal neuralgia (TN). Given their invasiveness, complications can result from such posterior fossa procedures, but the impact of these procedures and their complications on patient-reported outcome measures (PROM), such as quality of life and distress, are not well established. METHOD: Five years after surgery, patients who underwent first MVD or PSR for TN at one institution, between 1982 and 2002, were sent a self-completion assessment set containing a range of PROMs: the Short Form-12 (SF-12) questionnaire to assess quality of life, the Hospital Anxiety and Depression Scale (HADS) to assess distress, and a questionnaire containing questions about postoperative complications, their severity and impact on quality of life. These findings and demographic data were compared between MVD and PSR. RESULTS: One hundred and eighty-one of 245 (73.9%) patients after first MVD and 49 of 60 (81.7%) after PSR responded, and were included in analyses. The mean SF-12 scores of patients after MVD and PSR at five-year follow-up were significantly lower than English age-matched norms. Though there were no differences in SF-12 physical or mental component scores between the two procedures, patients after PSR were more likely to have case-level anxiety (RR = 3.3; 95% CI, 1.1-10.5; p = 0.03), had more postoperative complications, and of greater severity, including pain (RR = 2.52; 95% CI, 1.5-4.1; p < 0.001), numbness (RR = 5.9; 95% CI, 3.8-9.2; p < 0.001), burning sensations (RR = 3.0; 95% CI, 1.5-5.8; p = 0.001) and difficulty in eating (RR = 17.1; 95% CI, 5.6-53.1; p < 0.001), and these had a larger impact on quality of life for PSR compared to MVD. CONCLUSIONS: The quality of life 5 years after MVD or PSR is poorer than in the general population and associated with postoperative complications such as pain, numbness, burning sensation and difficulty in eating. These complications are commoner after PSR than MVD, and this is associated with anxiety in PSR patients at five-year follow-up. However, these differences are not reflected by quality of life scores. Outcome measures need to incorporate patient experience after treatment for TN, and represent patient priorities for quality of life
Do photographic images of pain improve communication during pain consultations?
BACKGROUND: Visual images may facilitate the communication of pain during consultations. OBJECTIVES: To assess whether photographic images of pain enrich the content andâor process of pain consultation by comparing patients' and clinicians' ratings of the consultation experience. METHODS: Photographic images of pain previously co-created by patients with a photographer were provided to new patients attending pain clinic consultations. Seventeen patients selected and used images that best expressed their pain and were compared with 21 patients who were not shown images. Ten clinicians conducted assessments in each condition. After consultation, patients and clinicians completed ratings of aspects of communication and, when images were used, how they influenced the consultation. RESULTS: The majority of both patients and clinicians reported that images enhanced the consultation. Ratings of communication were generally high, with no differences between those with and without images (with the exception of confidence in treatment plan, which was rated more highly in the image group). However, patients' and clinicians' ratings of communication were inversely related only in consultations with images. Methodological shortcomings may underlie the present findings of no difference. It is also possible that using images raised patients' and clinicians' expectations and encouraged emotional disclosure, in response to which clinicians were dissatisfied with their performance. CONCLUSIONS: Using images in clinical encounters did not have a negative impact on the consultation, nor did it improve communication or satisfaction. These findings will inform future analysis of behaviour in the video-recorded consultations
Comments: Trigeminal Nerve Compression Without Trigeminal Neuralgia: Intraoperative vs Imaging Evidence
Trigeminal neuralgia
Trigeminal neuralgia is a rare, episodic facial pain that is
unilateral, electric shock-like, and provoked by light touch. At
first, it is often mistaken as a tooth problem owing to its
presentation in the two lower branches of the trigeminal nerve.
Patients may undergo unnecessaryâand sometimes
irreversibleâdental treatment before the condition isrecognised.
Initially, a small dose of an antiepileptic drug (such as
carbamazepine) rather than any analgesic drug can provide
excellent pain relief. However, up to 10% of patients will not
respond to antiepileptic drugs,1
and in rare instances trigeminal
neuralgia can be secondary to a brain tumour, multiple sclerosis,
or vascular anomalies, which will be identified only on
neuroimaging.2
If quality of life becomes impaired and
symptoms are uncontrolled with drug treatment, patientsshould
be referred to a neurosurgeon for consideration of surgical
management. Studies in Europe have shown that trigeminal
neuralgia results in considerable interference with activities of
daily living that is comparable to other neuropathic pain
conditions,3
and could lead to suicide.4 This review aims to
highlight the key features of trigeminal neuralgia and familiarise
readers with both the medical and surgical management of this
condition, which remains based on limited evidence and expert
opinion
