Healing of a large avulsed mandibular bony segment: report of a unique case.

Int J Oral Maxillofac Surg 2021 Jun 5. Epub 2021 Jun 5.

Department of Oral and Maxillofacial Surgery, King Edward Medical University/Mayo Hospital, Lahore, Pakistan.

This case report puts an emphasis on retaining and re-fixing any avulsed bony segments in the maxillofacial region and maintaining the periosteal layer whenever possible, especially in young patients. Adequate bony fixation and watertight soft tissue closure are vital components for bone healing. The healing potential of facial bones is much higher as compared to the long bones, due to the superior blood supply. Read More

Impaired Callus Formation in Pathological Mandibular Fractures in Medication-Related Osteonecrosis of the Jaw and Osteoradionecrosis.

J Oral Maxillofac Surg 2021 Apr 28. Epub 2021 Apr 28.

Oral and Maxillofacial Surgery - Imaging and Pathology Research Group, Department of Imaging and Pathology, Faculty of Medicine, University of Leuven and Department of Oral & Maxillofacial Surgery, University of Leuven, Leuven, Belgium.

Purpose: Nonsurgical treatment of mandibular fractures secondary to medication-related osteonecrosis of the jaw (MRONJ) or osteoradionecrosis (ORN) mostly results in nonunion, whereas nonsurgical fracture treatment of atrophic fractures can achieve favorable results in selected cases. The aim of this study was to compare callus formation in pathological mandibular fractures due to MRONJ, ORN, or extreme mandibular atrophy.

Methods: A retrospective cohort study reviewing the medical records of all MRONJ-, ORN-, or atrophy-related fractures treated at the departments of maxillofacial surgery in the Leuven or Lille university hospitals between 2010 and 2019 was undertaken. Read More

A new classification of mandibular fractures.

Int J Oral Maxillofac Surg 2021 Jun 3. Epub 2021 Jun 3.

Liverpool Head and Neck Centre, Aintree University Hospital NHS Foundation Trust, Liverpool, UK.

There is no accepted method of reporting mandibular fracture that reflects incidence, treatment and outcome for individual cases. As most series include anatomical site only for all fractures, the aim was to establish a new method to report fractures based on a systematic review of the literature and an internal audit. The classification proposed is: Class I; condyle, II; angle, IIc; II+condyle, III; body/symphysis, IIIc; III+condyle, IV; multiple fractures not including condyle, IVc; IV+condyle, V; bilateral condyle±other fracture(s).

Variants and Modifications of the Retroauricular Approach Using in Temporomandibular Joint Surgery: A Systematic Review.

J Clin Med 2021 May 11;10(10). Epub 2021 May 11.

Department of Biochemistry and Medical Chemistry, Pomeranian Medical University, Powstańców Wielkopolskich 72, 70-111 Szczecin, Poland.
