Temporal tendinitis: a modified Levandoski panoramic analysis of 21 cases

Evaluation and management of temporomandibular disorders. Part 2: an orthopaedic physical therapy update on examination and clinical reasoning

Temporomandibular (TM) disorders afflict many people globally and, despite the presence of existing peer-reviewed material that assists conservative orthopedic providers, recent advances in knowledge indicate that updated resources are required for students, clinicians, and educators. This two-part series builds off previously published material to present newer supplementary information that can be useful during the evaluation and management processes. Content in Part 1 of this series includes a discussion about the factors that have been shown to contribute to TM disorders, an updated perspective of relevant pain science, a discussion of self-report outcome measures, and various different topics related to the examination of patients with TM disorders. Part 2 addresses information related to the temporomandibular joint disc, joint hypermobility, oral splints, and clinical reasoning. In combination with other available publications, this two-part series provides clinicians an opportunity to improve their delivery of effective and efficient clinical services for people diagnosed with TM disorders.

Temporal Tendinitis in Craniomandibular Dysfunction (CMD) - Does it Really Exist? A Temporomandibular MRI Investigation

OBJECTIVES

 The aim of the study was to analyze the role of temporal muscle and particularly tendon pathology in patients suffering from craniomandibular dysfunction (CMD) using magnetic resonance imaging.

MATERIALS AND METHODS

 Retrospective analysis of MRI examinations was carried out with regard to temporal muscle fibrosis and fatty degeneration and particularly temporal tendon rupture, thickening, and degenerative signal alterations. Descriptive statistics and the Mann-Whitney U-test were used for statistical evaluation.

RESULTS

 Structural lesions of temporal muscle parenchyma were the absolute exception. PD hyperintensity, pronounced contrast enhancement, or peritendinous fluid collections along the temporal tendon were found only to a small extent, and a (partial) rupture occurred in only one case. The tendon diameter showed only slight variability. The Mann-Whitney U-test provided no results indicating a causal connection between degenerative joint or disc disease and temporal tendon pathology.

CONCLUSION

 A large sample of 128 magnetic resonance imaging examinations provided no evidence of a major role of temporal tendinitis in clinical CMD syndrome.

KEY POINTS

  · Retrospective analysis of temporal tendon in CMD patients.. · Abnormal structural findings along the tendon seen only rarely.. · Obviously no crucial role of temporal tendon lesions in CMD syndrome..

Various diagnostic possibilities for zygomatic arch pain: Seven case reports and review of literature

BACKGROUND

Pain of the zygomatic arch region is common among patients with orofacial pain, especially in those with temporomandibular disorder-related pain of a myogenic origin. Since zygomatic arch pain may occur due to various causes other than muscle pain, appropriate diagnosis and treatment planning is essential to ensure its successful management. Unfortunately, zygomatic arch pain has not been handled as an independent clinical feature until now, and studies have mainly focused on pain resulting from trauma and surgical procedures.

CASE SUMMARY

We describe 7 independent cases, all of which presented with the identical chief complaint of pain in the zygomatic arch region. However, the underlying causes were different for each, being myofascial pain, myositis, tooth crack, dental caries, sinusitis, neuropathic pain, and salivary gland tumor respectively. In this case report, the clinical features of each case are investigated and diseases to be considered in the diagnostic process are suggested, along with the diagnostic modalities (including computed tomography and magnetic resonance imaging) that can lead to the appropriate final diagnosis.

CONCLUSION

Zygomatic arch pain is a common complaint encountered in the orofacial pain clinic but may lead to misdiagnosis. Clinicians must have in-depth knowledge of the possible differential diagnoses and evaluation tools.

Temporal tendinosis: A cause of chronic orofacial pain

PURPOSE OF REVIEW

Diverse musculoskeletal disorders and neuropathic symptoms of the face pose significant diagnostic challenges. In particular, temporal tendinosis is generally overlooked in the medical and dental literature and is therefore a poorly understood topic and often problematic cause of chronic orofacial pain. In this article, we explore temporal tendinosis as a cause of unresolved orofacial pain by reviewing the complex anatomy of the temporalis muscle, common presentations of temporal tendinosis, possible etiologies for injury and place a strong emphasis on required diagnostic evaluation and clinical management.

RECENT FINDINGS

Temporal tendinosis remains under diagnosed due to a combination of anatomical complexity and incomplete description in the majority of general anatomy medical textbooks. The two main presentations are unilateral facial pain with or without temporal headache and pain radiating from the distal temporalis tendon to the temporalis muscle. Diagnosis should be made with a combination of focused history, physical examination and specialised imaging, preferably with ultrasound but with MRI an alternate option. While many management options are available, optimal treatment remains unclear. Temporal tendinosis is an under-recognised and under-treated condition. Despite the fact that orofacial pain is one of the single most common complaints of patients presenting to physicians or dentists, it is widely acknowledged that training for diagnosis and manage of temporal tendinopathy among primary care physicians in both medical and dental professions is inadequate. This may result in extensive workups, leading to suboptimal management and chronic pain syndromes.
