Objective: The aim of this anatomical study was to determine if a needle is able to reach the lateral pterygoid muscle during the application of dry needling technique.
Methods: A dry needling approach using 2 needles of 50 to 60 mm in length, one inserted over the zygomatic process posterior at the obituary arch (for the superior head) and other inserted below the zygomatic process between the mandibular condyle and the coronoid process (for the inferior head), was proposed. A progressive dissection into 3 stages was conducted into 2 heads of fresh male cadavers. First, dry needling of the lateral pterygoid muscle was applied on the cadaver. Second, a block dissection containing the lateral pterygoid was harvested. Finally, the ramus of the mandible was sectioned by osteotomy to visualize the lateral pterygoid muscle with the needle placements.
Results: With the needles inserted into the cadaver, the block dissection revealed that the superior needle reached the superior (sphenoid) head of the lateral pterygoid muscle and the inferior needle reached the inferior (pterygoid) head of the muscle. At the final stage of the dissection, when the ramus of the mandible was sectioned by osteotomy, it was revealed that the superior needle entered into the belly of the superior head of the lateral pterygoid muscle.
Conclusions: This anatomical study supports that dry needling technique for the lateral pterygoid muscle can be properly conducted with the proposed approach.

In current alloplastic total temporomandibular joint replacements (TMJRs) typically the lateral pterygoid muscle (LPM) insertion is sacrificed, affecting joint function. This study assesses a novel additively manufactured TMJR (CADskills BV, Gent, Belgium) designed to enable LPM reinsertion through a scaffold feature on the implant. Thirteen TMJRs were implanted in Swifter crossbreed sheep, with follow-up CT scans after 288 days to evaluate LPM reintegration.

Background: The study aimed to investigate the effect of customized lateral nasal wall osteotomy (LNO) on the lateral nasal wall (LNW) and pterygomaxillary junction (PMJ) separation during Le Fort I. We hypothesized that customized LNO on the LNW affect the PMJ separation type.
Material And Methods: This prospective, controlled, randomized study included forty-three patients were randomly assigned to either the conventional or customized (study) osteotomy groups.

Purpose: The aim of this study is to obtain the anatomical limits of the parapharyngeal space by transoral surgical approach, in order to objectively determine the types of lesions according to location, where this type of approach is more indicated.
Methods: A prospective, experimental, radio-anatomical study was performed on 10 cryopreserved human heads(20 sides). A transoral approach of the parapharyngeal space was performed determining its anatomical limits by CT navigation.

Pterygomaxillary separation (PMS) is an important step in Le Fort I osteotomy procedure, without which complete mobilization of the maxilla cannot be achieved. The aim of this study was to evaluate PMS patterns and their relationship with the anatomic measurements in Le Fort I osteotomy. In this prospective observational study cone beam computed tomography (CBCT) was used to measure the anatomic variables of the pterygomaxillary junction (PMJ) region including thickness, width, the distance between the most concave point at the lateral surface of PMJ and the greater palatine foramen (C-GPF), and the angle preoperatively, and the separation patterns postoperatively divided into the clean-cut type, maxillary sinus type, and the pterygoid fracture type.

Background: Transesutural distraction osteogenesis (TSDO) is a method of correcting midfacial hypoplasia (MH) secondary to cleft lip and palate (CLP) without osteotomy. However, there has been little research on how the morphology of the cranial base changes postoperatively or whether any correction of the cranial base occurs.
Materials And Methods: This retrospective study included 35 pediatric patients with MH secondary to CLP, who underwent TSDO treatment.
