Kef K, et al. - Researchers conducted this prospective study of bruxism patients at Private Kesan Hospital otorhinolaryngology outpatient clinic with the aim to determine the effectiveness of botulinum toxin administration in patients who consulted the otolaryngology clinic with secondary otalgia caused by bruxism. Among a total of 37 included patients, nine (24.3%) had facial asymmetry due to masseter muscle hypertrophy. The participants were of average age of 34.00 ± 9.13 years old.
