OBJECTIVE: This study aimed to clarify frequency distribution of number and peak amplitude of electromyographic (EMG) waveforms of sleep bruxism (SB) in outpatients with clinical diagnosis of SB (probable bruxer: P-bruxer). METHODS: Subjects were 40 P-bruxers. Masseteric EMG during sleep was measured at home using a wearable EMG system. EMG waveforms with amplitude of more than two times the baseline and with duration of 0.25 s were extracted as SB bursts. Clusters of bursts, i...

BACKGROUND: Herniation of the temporomandibular joint (TMJ) into the external auditory canal (EAC) due to a bony defect in the EAC is rare. Such bony defects can be secondary to inflammation, neoplasm, trauma. In rare instances, TMJ herniation can occur when the Huschke foramen is constantly exposed. TMJ herniation can induce clicking tinnitus, otalgia, conductive hearing loss, and otorrhea, but can also present with no symptoms. This study reports a case of TMJ herniation. CLINICAL PRESENTATION: A male patient presented with clicking tinnitus that had developed 3 years ago...

OBJECTIVE: Evaluation of the presence of nasal septal deviation in patients presenting with obstructive sleep apnea (OSA) using Cone-Beam Computed Tomography (CBCT). METHOD: Patients diagnosed with OSA using polysomnography were further evaluated radiographically for the presence of nasal septal deviation, maxillary sinus septa, and oropharyngeal airway volume using CBCT. RESULTS: Nasal deviation was present in all the patients and was classified according to Negus et al classification, further categorized with Apnea-hypopnea index (AHI) score, maxillary sinus septa in those patients were classified according to Al Faraj et al, and the oropharyngeal airway volume was found to be an average of 10,086...
