“…The gender difference in signs and symptoms was small in childhood [12], but from late adolescence, women have been reported more symptoms and exhibited more clinical signs than men did (1.5-2 times more prevalent in women than in men) [5]. Muscular disorders, as lateral pterygoid muscle tenderness, showed greater prevalence among girls [20], but this finding must be interpreted carefully due to the low specificity of intra-oral muscle palpation, since the discomfort or pain observed in response to palpation of the ''lateral pterygoid area'' may be caused by anatomical structures other than the lateral pterygoid muscle [21]. One contributing factor to this gender difference might be that women have a greater sensitivity to pain than men.…”

“…Although significant adverse events have not been largely described, there is a potential risk when the LPM BTX injection is carried out under EMG guidance, since the anatomical structures are not clearly identified. In fact, even the inferior LPM palpation is difficult and it has not been recommended in the clinical routine examination for temporomandibular disorders (TMDs), since there is a high possibility of false-positive findings [22]. The use of a patient-specific guide to orient the direction of the needle during the BTX injection in the LPM allows the proper differentiation between the superior and inferior LPM.…”

Background. The uncoordinated activity of the superior and inferior parts of the lateral pterygoid muscle (LPM) has been suggested to be one of the causes of temporomandibular joint (TMJ) disc displacement. A therapy for this muscle disorder is the injection of botulinum toxin (BTX), of the LPM. However, there is a potential risk of side effects with the injection guide methods currently available. In addition, they do not permit appropriate differentiation between the two bellies of the muscle. Herein, a novel method is presented to provide intraoral access to the superior head of the human LPM with maximal control and minimal hazards. Methods. Computational tomography along with digital imaging software programs and rapid prototyping techniques were used to create a rapid prototyped guide to orient BTX injections in the superior LPM. Results. The method proved to be feasible and reliable. Furthermore, when tested in one volunteer it allowed precise access to the upper head of LPM, without producing side effects. Conclusions. The prototyped guide presented in this paper is a novel tool that provides intraoral access to the superior head of the LPM. Further studies will be necessary to test the efficacy and validate this method in a larger cohort of subjects.

“…The current cadaveric anatomical study supports that dry needling of the lateral pterygoid muscle can be properly performed with the proposed approach. This is clinically important as some authors claimed that the lateral pterygoid muscle is not accessible to manual palpation 8,9 ; therefore, dry needling may represent the proper therapeutic approach for management of TMD.…”

“…8,9 Deep dry needling (an invasive procedure where an acupuncture needle is introduced into the muscle) has been advocated as a possible therapeutic tool for the management of this muscle. Dıraçoğlu et al 10 reported that point-specific dry needling was more effective than non-point-specific needling for the management of TMD.…”
