“…However, continu- Fairly often, we encounter cases of trismus in our daily dental practice. Many cases are associated with TMD [7]. Since trismus is associated with various disorders, such as inflammation, tumors, and scar contracture, dentists often encounter cases in which accurate diagnosis is difficult.…”

“…MRI is useful for ascertaining abnormal findings suggestive of inflammatory diseases of inside tissue (e.g., the medial pterygoid muscle) [8]. Kamio et al [7] used MRI to examine the head and neck region in patients with suspected TMD. They observed clinical findings and signs similar to TMD, such as pain and trismus, in 21 patients, more than half of whom presented with mandibular osteomyelitis.…”

A 34-year-old woman visited our clinic with complaints of trismus, numbness in the left half of the tongue, and pain in tooth 34. At the patient's initial visit to our clinic, the maximum assisted jaw opening movement was 20 mm, pointing to severe trismus. The patient complained of spontaneous pain in tooth 34 but did not evince percussion pain. Her pain remained unchanged even under local anesthesia. Radiography showed no pathological findings. A tenderness test of masticatory muscles failed to induce pain. The presence of severe trismus argued against temporomandibular disorders, resulting in suspicion of other inflammatory disease. In view of numbness of the tongue, other diseases such as inflammation or neoplastic disease in the head and neck region were considered. The patient was referred to the departments of neurosurgery and otolaryngology for examination. The results of MRI and CT diagnosis led to the identification of acute myositis of the left medial pterygoid muscle requiring the prescription of nonsteroidal anti-inflammatory drugs, and relaxation of mandibular muscles. With time, maximum unassisted jaw opening improved and pain in tooth 34 ceased, but tongue numbness persisted. The condition was attributed to compression of lingual nerve (LN) and mandibular nerve (MN) resulting from medial pterygoid muscle inflammation.

“…Most of the studies included in the meta-analysis were conducted in adults, 6 studies were conducted in pediatric cohorts, 4,10,[17][18][19][20] and 10 studies 8,[21][22][23][24][25][26][27][28][29] were in a mixed patient cohort. The breakdown of the 33 studies into population groups was as follows: 1 study in group 1 (specific symptom screening with endoscopy), 16 in group 2 (specific symptom screening without endoscopy), and 16 in group 3 (no specific screening).…”

“…Six of the 33 studies 21,23,[31][32][33][34] included in the metaanalyses elsewhere did not state their cutoff for classifying significant mucosal thickening but reported a combined prevalence of 21.3% of some degree of thickening. Nine of the studies excluded from the meta-analysis due to incomplete data found a combined 12.8% prevalence of some degree of maxillary sinus mucosal thickening.…”

Objective To determine the range of incidental mucosal changes in a general sinonasally asymptomatic population on radiology. Data Sources Medline (1996-present) and Embase (1974-present) were searched on March 14, 2020, to identify articles that reported radiological sinus mucosal findings in asymptomatic population groups. Bibliographic search of included studies was conducted to identify additional articles. Review Methods The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and Cochrane Handbook for Systematic Reviews of Interventions. A comprehensive search strategy was formulated and articles screened to extract data reporting Lund-Mackay (LM) score, presence of mucous retention cysts, and maxillary mucosal thickening. A random-effects model was used in meta-analysis. Results A total of 950 articles were identified, of which 33 manuscripts met the inclusion criteria. The included studies involved 16,966 sinonasally asymptomatic subjects. The mean LM score was 2.24 (95% CI, 1.61-2.87), and an LM score of ≥4 in 14.71% (95% CI, 6.86-24.82%) was present across all general asymptomatic population groups. Mucous retention cysts were noted in 13% (95% CI, 8.33-18.55%) and maxillary mucosal thickening of ≥2 mm in 17.73% (95% CI, 8.67-29.08%). Conclusion The prevalence of incidental mucosal changes in a general asymptomatic population on radiology needs to be considered when making a diagnosis of chronic rhinosinusitis.

“…Paranasal sinus abnormalities are described during brain MRI performed to determine sinus-associated abnormalities [ 2 ]. A wide range of sinus abnormalities can be visualized during brain MRI scanning, which gives the advantage of cross-sectional imaging [ 3 , 4 ]. These days, there is an increase in the frequency of brain imaging, including the paranasal sinuses [ 2 ].…”

The aim of this study is to assess the incidence and kinds of paranasal sinus pathology in patients presenting for brain MRI as referred from general practice or neurologist physicians in Qassim region, Saudi Arabia. MethodsThis cross-sectional study included 210 patients with different neurological indications and presentations who underwent an MRI of the brain and were evaluated by the consultant radiologist for the presence of any paranasal sinuses pathologies such as mucosal thickening, retention cyst, opacification, and ostiomeatal complex obliteration. The analysis was carried out using the chi-square test. ResultsA total of 210 cases underwent brain MRI to evaluate clinically suspected brain disorders; there were 138 (65.7 %) males and 72 (34.3%) females. Mucosal thickening was the commonest pathological finding (111 cases, 52.9%). retention cysts were present in around 14.3%, meaning 30 cases, and partial opacification was present in around 10%, representing 21 cases. Total opacification was present in three (1.4%) cases. Also, ostiomeatal complex obliteration was present in three (1.4%) cases. Paranasal pathological findings were more in those aged ≤ 35 years, with 75 (35.7%) cases. mucosal thickening, partial opacification, total opacification, and ostiomeatal complex obliteration were more in males, whereas retention cysts were equal in both genders. ConclusionPathological paranasal sinuses findings commonly occur at brain MRI during neurological disorder evaluation. These findings are usually benign, and mucosal thickening is the commonest. The majority of the pathological findings were observed in those aged ≤ 35 years and in the male gender. Detecting pathological findings in paranasal sinuses helps diagnose lesions unrelated to the suspected neurological disease.
