The mucous cyst, a rare and delayed complication after rhinoplasty.

INTRODUCTION: Rhinoplasty is frequently performed worldwide, and patients and surgeons both expect good cosmetic results without any deformity recurrence. We report a rare case of mucous cyst occurred after post-traumatic rhinoseptoplasty. OBSERVATION: A 27-year old woman presented a median mass of the nose root 7 years after prior rhinoseptoplasty. Investigations showed a subcutaneous lesion of 10.5×24.5mm. The surgery consisted on an external rhinoplasty allowing cyst removal, bilateral osteotomies and reconstruction of the nasal dorsum by deep temporal fascia graft. Histological examination confirmed the diagnosis of begnin mucous cyst. No recurrence was observed at 1-year follow-up. DISCUSSION: Mucous cyst post rhinoplasty is rare and is probably due to accidental mucosal material implantation into the subcutaneous plane during rhinoplasty. This complication can be avoided by adequate infiltration and hydrodissection, careful dissection, and avoidance of unnecessary trauma during osteotomies.

Optimized centrifugation preparation of the platelet rich plasma: Literature review.

Nowadays, the Platelet Rich Plasma (PRP) is frequently used for its therapeutic effects on wound healing, and this due to secretion of many growth factors. However, no standardized procedure has been set up. The aim of this article is to check the various preparations (centrifugation time and speed). This review recorded all the international articles published between 2007 and 2018, for which the assessment criteria were the platelet concentration and/or the growth factor release rate. A multitude of protocols has been looked at with a simple or double centrifugation. All of them have shown an increase in the platelet concentration allowing a therapeutic effect. However, when the centrifugation force is extended, platelets can possibly be altered. The diversity of methods can be linked to the use of various centrifuges. A procedure with simple centrifugation would be a good compromise for the day-to-day use of the PRP in surgery.

About a pediatric facial trauma.

Less-lethal weapon are more and more used in law enforcement to neutralize combative individuals and to disperse riot crowds. Even if this type of weapon has been created to be less damaging than classical firearms, it has been incriminated many times in cases of facial injuries with functional consequences, even death. In many countries, these guns can be possessed by average citizens. They could be extremely harmful when handled by inexperienced users and cannot be considered solely as defense weapons. Interestingly, little literature is available concerning facial injuries caused by the less-lethal weapons. We report the case of a ballistic wound on a 3-year-old child.

Management of isolated and complex craniosynostosis residual deformities: What are the maxillofacial tools?

Treatment of craniosynostosis is complex and has greatly progressed in recent decades. From the early stages in the 1950s to today's most recent techniques, surgeons have faced the challenge of overcoming the deformities often caused by such invasive, complex surgeries. In the most recent years, new techniques have been developed that address surgical sequelae, including those of surgery performed in childhood. After a general introduction on craniosynostosis, the present paper describes the various types of deformity that may result from complex surgery and offers an overview of the various tools available to surgeons. An explanation of each indication and procedure is given.
