Purpose: This study compared transport distraction with costochondral graft in the reconstruction of temporomandibular joint (TMJ) with disc preservation.
Materials And Methods: Bilateral condylectomies with disc preservation were conducted in 12 adult goats. Transport distraction of the mandibular ramus was performed on 1 side and costochondral graft on the other side. Jaw movements, TMJ healing, and condylar remodeling were assessed by clinical, radiologic, and histologic examinations.
Results: Transport distraction and costochondral graft established a new condyle separating from the preserved disc with a joint space. Both techniques showed no significant difference in ankylosis scores up to 24 weeks. Signs of calcification were not noted in the transport distraction or costochondral graft side. No significant change of maximal jaw movements was found at any time point from 2 to 24 weeks.
Conclusions: Distraction osteogenesis is an effective reconstruction method for TMJ reconstruction. No significant difference between these 2 techniques in reconstruction of the TMJ was noted.

Article Synopsis
- The free fibular flap (FFF) is an effective method for reconstructing maxillofacial defects and serves as a viable alternative for patients with micrognathia when traditional surgeries can't be performed.
- A case study of a 28-year-old woman highlights the successful use of FFF for lengthening her mandible, after previous TMJ surgery caused difficulties in mouth opening and other functional challenges.
- Post-surgery, the patient showed significant improvements in aesthetics, occlusal function, and symptoms of obstructive sleep apnea, demonstrating the effectiveness of FFF in treating micrognathia.
Mandibular Condylar Head Regeneration Owing to Remodeling of the Costochondral Graft After Condylectomy for Odontogenic Myxoma.

Odontogenic myxoma of the mandibular condyle is a rare tumor that requires complete surgical resection because of the tendency for recurrence. The right mandibular condyle was resected to remove the myxoma. The author performed immediate condylar reconstruction using a costochondral graft (CCG), and stable temporomandibular joint (TMJ) function and occlusion were achieved.

Introduction And Importance: Temporomandibular joint (TMJ) ankylosis in children severely impacts mouth opening, orofacial growth, airway space, and overall quality of life. While costochondral grafts (CCG) are the gold standard for end-stage TMJ reconstruction in children, their unpredictable growth poses challenges, including potential overgrowth, undergrowth, resorption, and reankylosis. However, recent reports have suggested the feasibility of alloplastic TMJ in pediatric patients.

Background: Performing rhinoplasty in patients with craniofacial malformations remains a challenge, even for experienced surgeons. Advances in 3D technology and its application in surgical planning and printing of cutting guides and splints have become important tools to improve aesthetic and functional results.
Objectives: To describe an in-house workflow for surgical planning and printing of cutting guides and splints for complex rhinoplasty cases.
Consultations for Poland Syndrome: The Essentials for a Thoracic Surgeon.

Poland syndrome (PS) is a rare congenital musculoskeletal entity occurring in approximately 1 in 30,000 newborns that manifests with variable symbrachydactyly, ipsilateral costochondral deformities, an absence of pectoral muscles, and breast underdevelopment. These have potential impacts on social, somatic, and psychological functionality, often leading affected individuals to seek expert opinions on corrective surgery. Due to phenotypic variability, strict management guidelines are lacking, with treatment decisions often based on the specialist's personal experience rather than published evidence.
