Classification of pedicle ossification after maxillofacial reconstruction with bony free flap: An observational study.

Introduction: Maxillofacial reconstruction with bony free flap is a classical technique. However, pedicle ossification after such reconstruction is a misunderstood complication that is rarely reported in the literature. It is usually manifested as trismus, neck pain, and hard swelling, but it is predominantly asymptomatic and, thus, mainly incidentally discovered at a later stage.

[Labial recurrent swelling revealing median congenital upper-lip fistula].

Midline upper-lip fistulas are an extremely rare variant of congenital facial malformations. Less than 30 cases have been reported in the literature since 1970. We report the case of a 2 and a half-year-old girl presenting with a median congenital blind fistula of the upper lip, without any relation with the oral cavity.

[Pneumoparotid: a rare cause of recurrent parotid swelling].

Introduction: Pneumoparotid is a rare cause of recurrent parotid swelling. It is often fortuitous, caused by an action inducing intraoral pressure, increased or self-induced.

Observation: An 8-year-old boy presented with recurrent right unilateral parotid swelling for 2 years.

Consequences of bony free flap's pedicle calcification after jaw reconstruction.

Introduction: Most of the time, discovery of free flap pedicle calcification is fortuitous. We describe this phenomenon, try to elucidate its consequences, and discuss about prevention. We studied the effect of radiotherapy on the onset of calcification.

[Engineering a bone free flap for maxillofacial reconstruction: technical restrictions].

Vascularisation is a key for success in bone tissue engineering. Creating a functional vascular network is an important concern so as to ensure vitality in regenerated tissues. Many strategies were developed to achieve this goal.

[Oro-maxillofacial bone tissue engineering combining biomaterials, stem cells, and gene therapy].

Improvements have been made in regenerative medicine, due to the development of tissue engineering and cellular therapy. Bone regeneration is an ambitious project, leading to many applications involving skull, maxillofacial, and orthopaedic surgery. Scaffolds, stem cells, and signals support bone tissue engineering.

[Palatal necrosis due to cocaine abuse].

The easier access to cocaine allows chronic and intensive consumption. Nasally inhaled cocaine causes important midfacial lesions called: Cocaine Induced Midline Destructive Lesions. These lesions are due to several factors, the anesthetic, vasoconstrictive, locally prothrombotic properties of cocaine and its components combined with cytotoxic effects and traumatic nasal injuries related to consumption mode.
