Selective augmentation of stem cell populations in structural fat grafts for maxillofacial surgery.

Structural fat grafting utilizes the centrifugation of liposuction aspirates to create a graded density of adipose tissue. This study was performed to qualitatively investigate the effects of centrifugation on stem cells present in adipose tissue. Liposuction aspirates were obtained from healthy donors and either not centrifuged or centrifuged at 1,800 rpm for 3 minutes.

Management of temporomandibular joint reankylosis in syndromic patients corrected with joint prostheses: surgical and rehabilitation protocols.

Temporomandibular joint ankylosis (TMJA) is a severe disorder described as an intracapsular union of the disc-condyle complex to the temporal articular surface with bony fusion. The management of this disability is challenging and rarely based on surgical and rehabilitation protocols. We describe the treatment in two young adults affected by Goldenhar syndrome and Pierre Robin sequence with reankylosis after previous surgical treatments.

Three-dimensional volumetric restoration by structural fat grafting.

The use of adipose tissue transfer for correction of maxillofacial defects was reported for the first time at the end of the 19th century. Structural fat grafting (SFG) was introduced as a way to improve facial esthetics and in recent years has evolved into applications in craniomaxillofacial reconstructive surgery. Several techniques have been proposed for harvesting and grafting the fat.

Peripheral ameloblastoma: case report.

Ameloblastoma is a benign tumour of the odontogenic tissues which may be aggressive in the involved area with a high rate of recurrence if not adequately removed, and represents 1% of all tumours of the mouth, generally appearing in the bones of the jaw. Although it is fairly rare, tumours with such histopathology have been described in the soft tissue and are named peripheral or extraosseus ameloblastoma. Potential cells of origin are ondontogenic residue of the dental lamina, pluripotent cells in the basal layer of the epithelial mucosa, and pluripotent cells of the minor salivary glands.

Eosinophilic angiocentric fibrosis.

Eosinophilic angiocentric fibrosis (EAF) is a rare disease of the sinonasal tract, with histologic characteristic features like thick collagen bundles whirling around vessels in a fibrotic stroma with inflammatory cells rich in eosinophils. The Authors present a case of a 31-year-old man with bilateral nasal obstruction with no history of allergies or other systemic disease. The patient underwent a septoplasty with symptoms relieving.
