Mechanical characterization of soft-tissue stiffness during mandibular distraction.

The purpose of this study was to determine the stiffness of mandibular soft tissues during mandibular distraction, from the perspective of improving distraction devices such as automated continuous distractors. Uncompleted osteotomy was performed on 11 fresh human hemimandibles via a greenstick fracture, to preserve the uplift of the internal periosteum of the mandibular corpus. In order to replicate continuous distraction, direct measurements were performed through a uniaxial quasi-static tensile test.

Management after fibula free flap necrosis in maxillofacial reconstruction.

Introduction: Few articles discuss the management of a free fibula flap (FFF) necrosis in maxillofacial reconstruction.

Material & Methods: Between 2005 and 2020, 170 FFF were used for maxillofacial reconstruction at the University Hospital of Caen, among which 16 cases suffered total necrosis and flap removal. The authors categorized these 16 cases into three groups based on the proposed salvage treatment and analyzed the post-operative follow-up, including complications, length of hospital stay and delay in radiotherapy.

Rerouting the internal thoracic vessels as recipient vessels in head and neck reconstruction: Comparison of two anatomic approaches.

Introduction: The vessel-depleted neck situation is a challenge for the surgeon in search of suitable recipient vessels for microvascular reconstruction of the head and neck. The internal thoracic vessels (ITVs) have proven useful as "rescue" recipient vessel resource. The objective of this report is to assess the feasibility of using ITVs by rerouting the pedicle for free flap reconstruction of the head and neck by comparing two different approaches.
