“…Consequently, the anterior border of the coronoid processes appeared hyperechoic just below the occlusal plane of the maxillary second molar in all US images (Figure 2). According to several studies (Dunn et al, 1996;Harn & Shackelford, 1982;Parker et al, 2012;Yu et al, 2021), the attachment of tendons to the coronoid process of the temporalis muscle shows significant variability, and the anatomical variations at the myotendinous junction make it challenging to clearly distinguish between the muscle and tendon. However, in the intraoral US images obtained in this study, we were able to identify the temporalis muscle surrounding the coronoid process as hypoechoic structures.…”

“…Based on the measured horizontal distances at the MP, the anterior border of the coronoid process was within a maximum of 5.41 mm and a minimum of 0.27 mm anteriorly from the MP. Medial portions of the temporalis tendon are reportedly located at an average of 1.4 cm in width and 5.2 cm in height from the lingula of mandible to the anterior border of the ramus (Dunn et al, 1996;Geers et al, 2005;Parker et al, 2012). Therefore, in type A cases, injections targeting the temporalis tendon could often be administered at the location of the maxillary second molar, even when considering the maximum and minimum values of the observed horizontal distance for the coronoid process.…”

Temporal tendinitis is characterized by acute inflammation often resulting from mechanical stress, such as repetitive jaw movements associated with jaw opening and closing and teeth clenching. Treatment for temporal tendinitis typically involves the administration of local anesthetic or corticosteroid injections. However, the complex anatomical structure of the coronoid process, to which the temporalis tendon attaches, located deep within the zygomatic arch, poses challenges for accurate injections. In this study, we aimed to establish guidelines for the safe and effective treatment of temporal tendinitis by using intraoral ultrasonography (US) to identify the anatomical structures surrounding the temporalis tendon and coronoid process. US was performed using an intraoral transducer on 58 volunteers without temporomandibular joint disease. The procedure involved placing the transducer below the occlusal plane of the maxillary second molar. Measurements were taken for the horizontal distance from the anterior border of the coronoid process, observed at the midpoint (MP) of the US images, and the depth of the coronoid process and temporalis muscle from the oral mucosa. The anterior border of the coronoid process was visualized on all US images and classified into three observed patterns at the MP: type A (anterior to the MP, 56.2%), type B (at the MP, 16.1%), and type C (posterior to the MP, 27.7%). The temporalis muscle was located at a mean depth of 3.12 ± 0.68 mm from the oral mucosa. The maxillary second molar is an intraoral landmark for visualizing the anterior border of the coronoid process. The new location information obtained using intraoral US could help identify the safest and most effective injection sites for the treatment of temporal tendinitis.

“…A series of vascular structures also reside in the midfacial corridor including the facial artery, facial vein, transverse facial artery, transverse facial vein and the buccal artery that branches from the maxillary artery and anastomoses with the facial artery. 7 8 Minor salivary glands and lymphatic structures are also present. The average dimensions of the space are 2.5 cm wide, 1 cm high and 9 cm in length.…”

Introduction Fascia lata and tendon grafts are frequently utilized to support the paralyzed midface and to extend muscular reach in McLaughin style, orthodromic temporalis transfers. The grafts are frequently placed in a deep subcutaneous positioning that can lead to the development of a, bowstring deformity in the cheek. This paper describes insertion of tendon grafts into the midfacial corridor collectively formed by the buccal, submasseteric and superficial temporal spaces. Methods Over a seven-year period, all patients that underwent insertion of facia lata and tendon grafts in the midfacial corridor were included. Demographic information, perioperative variables and clinical outcomes were collected and analyzed. Results A total of 22 patients were included with a mean age of 64.3 years (33–86). There were multiple etiologies for the facial weakness including acoustic neuroma (9.1%), Bell's palsy (13.6%), facial nerve schwannoma (9.1%), temporal bone fracture (4.6%) and malignancy (22.7%). Midfacial corridor grafts were utilized in combination with nerve transfers (V-VII and XII-VII) in nine patients, McLaughin style temporalis transfers in 12 and as a standalone procedure in one individual. During the study period, no patients exhibited a tethering, or concave deformity in the midface. Additionally, no impingement, difficulties with mastication, parotitis or hematoma were encountered. One patient developed a postoperative infection, that was successfully managed. Conclusion Placement of tendon or fascia grafts for static support or tunneling of an orthodromic temporalis transfer through the midfacial corridor can be performed rapidly while providing midfacial support and avoiding the creation of visible cutaneous deformities.
