Rationale: The rationale was to establish a permanent surgical solution for nonreducing dislocations of the temporomandibular joint (TMJ).
Patient Concerns: The patient presents with a long-standing history of chronic subluxation of the TMJ bilaterally, with the need to forcibly manipulate and reduce the dislocated jaw.
Diagnosis: Chronic recurrent dislocation of the TMJ.
Treatment: A modified Dautrey's procedure was performed on the right side, with the osteotomized segment being transferred medially and inferiorly.
Outcome: After 5 years of follow-up, there was no incidence of recurrent dislocation.
Take-away Lesson: This modification is a viable option in both unilateral and bilateral reducing and nonreducing dislocations.

Purpose: The authors evaluated pterygomaxillary junction angles across malocclusion patterns and identified the optimal technique for effective pterygomaxillary junction separation during Le Fort I osteotomy, focusing on appropriate osteotome angles and clinical applications.
Methods: This retrospective study included 211 patients with malocclusion who had undergone Le Fort I osteotomy at Chang Gung Craniofacial Center between December 2015 and September 2023. The patients were stratified by sex and malocclusion class (class I, II, or III).

This study introduced and analyzed the clinical effects of a modified Dautrey's procedure, involving down-fracture of the zygomatic arch and articular tubercle augmentation, for the treatment of recurrent TMJ dislocation. Recurrent TMJ dislocation patients were treated using the modified Dautrey's procedure. The recurrence of joint dislocation, maximal mouth opening (MMO), and pain were evaluated postoperatively.

Aerial images obtained by drones are increasingly used for ecological research such as wildlife monitoring. Yet detectability issues resulting from animal activity or visibility are rarely considered, although these may lead to biased population size and trend estimates. In this study, we investigated detectability in a census of Malagasy pond heron Ardeola idae colonies on the island of Mayotte.

This study aimed to introduce the clinical application of the CAD/CAM-guided modified Dautrey's procedure in recurrent anterior temporomandibular joint luxation and evaluate its clinical effects. Four selected patients were treated by the CAD/CAM-guided modified Dautrey's procedure and were followed-up to access their curative effect. Joint pain and sound, recurrence rate, mandibular function, maximum mouth opening (MMO), symptoms of facial nerve injury, and changes in zygomatic facial appearance were observed in postoperative follow-up.

Clinical T4b oral squamous cell carcinoma is traditionally considered nonoperable. We present a case of right mandibular squamous cell carcinoma (PT4bN0M0, stage IVB). The tumor had extended to the right mandibular condylar head and masticatory space.
