Despite the study limitations, ultrasonography (US) is able to detect subacromial space narrowing in young overhead athletes as early shoulder impingement sign, according to the continuum impingement-instability pathologic model.

The classical sinus lift procedure is a well-docume- nted technique and Schneiderian membrane perfora-tion is one of the most common complications. Vari-ous repairs have been developed for managing sinus membrane perforations. We describe a new suture technique of Schneiderian membrane that makes it possible to complete a sinus lift procedure that oth-erwise might have been aborted by preventing loss of the graft in the sinus cavity and secondary complica-tions, such as sinusitis

The management of frontal bone injury is an important issue, and inappropriate management of such injuries may give rise to serious complications. Piezosurgery is a technique used to perform safe and effective osteotomies using piezoelectric ultrasonic vibrations. This instrument allows a safe method for osteotomy of the cranial vault in close proximity to extremely injury-sensitive tissue such as the brain. After a wide review of the literature, the authors present this technical report, introduce the use of piezosurgery to perform a safe "slim-osteotomies" for treatment of posttraumatic frontal bone deformities, and suggest the use of this instrument for aesthetic recontouring of the craniofacial skeleton.

The literature-reported incidence of ophthalmic injuries occurring with facial fracture ranges widely from 0.8% to 30%. Ocular trauma necessitating enucleation or evisceration is less common, but it is not rare. The trauma and physical disability related to removal of the eye are extreme. Moreover, the loss of an eye causes severe changes to the anatomy and physiology of the orbit, resulting in deformities that affect the relationship between the socket and the prosthesis. Here, the authors present their own experience of 8 consecutive cases of trauma injuries with globe loss and emphasize the importance of accurate, early bone reconstruction involving evisceration and immediate socket restoration.
