Objective: To report our experience with mandibular resection and reconstruction using vascularized bone-containing free flaps without an elective tracheostomy.

Study Design: Case series with chart review.

Setting: Tertiary referral hospital center.

Subjects And Methods: Sixty-six patients undergoing mandibular reconstruction with vascularized bone-containing free flaps without an elective tracheostomy were identified between 1995 and 2013. We describe patient, tumor, and surgical factors and report perioperative outcomes in this population.

Results: Most patients underwent fibula free flap reconstruction (n = 61, 92.44%). The 4 most frequent indications for resection were osteoradionecrosis, parotid carcinoma, oral squamous cell carcinoma, and osteomyelitis. Bone defects ranging from 4.0 to 13.0 cm were reconstructed, and associated soft-tissue defects were reconstructed with skin paddle sizes ranging from 24.0 to 450.0 cm(2). There was only 1 patient with a bilateral central mandibular defect, and there were no tongue/pharyngeal soft-tissue defects or bilateral neck dissections. One case required emergent tracheostomy on postoperative day 1, and 2 more patients developed respiratory complications. There were no cases of perioperative death or flap failure.

Conclusion: Mandibular free flap reconstruction is feasible without an elective tracheostomy in a subset of carefully selected patients without bilateral central mandibular defects, tongue/pharynx defects, or bilateral neck dissection.

Immune-mediated bone regeneration driven by bone biomaterials offers a therapeutic strategy for repairing bone defects. Among 2D nanomaterials, TiCT MXenes have garnered substantial attention for their potential in tissue regeneration. This investigation concentrates on the role of MXene nanocomposites in modulating the immune microenvironment within bone defects to facilitate bone tissue restoration.

This novel hybrid single-double-single barrel (1-2-1) design for fibula free flap reconstruction addresses the unique challenges presented by Brown Class III mandibular defects, which involve long-span defects at both bodies of the mandible and the chin. The importance of this design lies in its ability to overcome the limitations of traditional approaches in terms of mandible height and pedicle length, while optimizing both functional and esthetic outcomes.The technique utilizes a combination of single-double-single barrel fibula segments to achieve ideal esthetics and support for dental prosthesis across different areas of the mandible.

Article Synopsis
  • Uremic leontiasis ossia (ULO) is a rare condition linked to renal osteodystrophy in patients with end-stage chronic kidney disease (CKD) and secondary hyperparathyroidism (SHPTH), causing bone deformities that can lead to a 'leonine' facial appearance.
  • The case study focuses on a 39-year-old female patient undergoing treatment, who exhibited significant symptoms and had elevated parathyroid hormone (PTH) levels, confirmed by CT scans.
  • Treatment involves a multidisciplinary approach including surgery and management of SHPTH to correct anatomical issues and prevent further complications.

A non-metallic PEEK topology optimization reconstruction implant for large mandibular continuity defects, validated using the MANDYBILATOR apparatus.

In cases of large mandibular continuity defects resulting from malignancy resection, the current standard of care involves using patient-specific/custom titanium reconstruction plates along with autogenous grafts (fibula, scapula, or iliac crest segments). However, when grafts are not feasible or desired, only the reconstruction plate is used to bridge the gap. Unfortunately, metal osteosynthesis and reconstruction plates, including titanium, exhibit adverse effects such as stress-shielding and limitations in accurate postoperative irradiation (especially with proton-beam therapy).

Background: To evaluate the prevalence and characteristics of taurodontism in northern China by using cone-beam computed tomography (CBCT) and assisting the treatment.

Methods: The study involved CBCT scans of 8112 teeth from 507 participants of northern China, comprising 217 males and 290 females aged 18 to 60. Analysis was conducted using Shifman and Chanannel's criteria to assess the prevalence and attributes of taurodontism, examining differences based on tooth position (maxilla and mandible) as well as gender (P < 0.
