Controversies in Revision Rhinoplasty.

Revision rhinoplasty is a complex operation with many variables that may influence the final esthetic and functional outcome of the procedure. Cartilage forms the structural framework of the lower two-thirds of nose and is essential for long-term support and maintenance of a patent nasal airway. The use of autologous cartilage grafting is the primary source of this material, limited by donor site quantity, quality, and harvest morbidity.

Rhinoplasty of the Aging Nose.

The process of aging leads to countless bodily changes on both a macro- and microscopic scale. No organ system is unaffected; however, the nose is especially susceptible. Sun damage, hormone levels, regenerative capability, tissue elasticity, bone resorption, and the effects of gravity contribute to produce classic signs and symptoms.

Management of nasoethmoid fractures.

Purpose Of Review: The management of nasoethmoid or naso-orbito-ethmoid (NOE) fractures requires a thorough knowledge of the central facial anatomy, surgical techniques, available tools and patient factors to obtain optimal restoration of aesthetic form and function. This review article describes the current methods of NOE fracture diagnosis, classification, surgical techniques and complication management, with a review of the current literature published over the past 18 months.

Recent Findings: Advanced imaging modalities, bioabsorbable versus titanium rigid fixation, nasolacrimal duct stenting, NOE fracture management in children and the elderly, and novel techniques of medial canthopexy.

Inner ear dysfunction in caspase-3 deficient mice.

Background: Caspase-3 is one of the most downstream enzymes activated in the apoptotic pathway. In caspase-3 deficient mice, loss of cochlear hair cells and spiral ganglion cells coincide closely with hearing loss. In contrast with the auditory system, details of the vestibular phenotype have not been characterized.
