The present study was aimed at describing the anatomy of nasal turbinates in adult Yankasa sheep using sectional anatomical planes and light microscopy. A total 5 heads were used. gross observations presented midsagittal serialized transverse sections. cavity comprised dorsal, middle ventral turbinates. These delineated by middle, common meatuses distinct morphological details different levels ...

Relapsing polychondritis (RPC) is a unique and rarely observed autoimmune condition regarded as recurrent extensive chondritis of the auricular, nasal, and tracheal cartilages. Moreover, heart, main arteries, skin, and eyes may be involved. Several forms of clinical manifestations may be seen, and the pathogenesis still remains anonymous. A concomitant disease, particularly myelodysplasia or ot...

INTRODUCTION The complexity of the nasal tip structures and the impact of surgical maneuvers make the prediction of the final outcome very difficult. Therefore, no single technique is enough to correct the several anatomical presentations, and adequate preoperative planning represents the basis of rhinoplasty. OBJECTIVE To present results of rhinoplasty, through the gradual surgical approach ...

OBJECTIVE To describe in detail a technique to achieve cephalic rotation, projection, and narrowing of the nasal tip, the "new domes" technique. DESIGN Retrospective analysis of more than 3000 primary rhinoplasties performed during the last 20 years. SETTING A private facial plastic surgery practice in Bogotá, Colombia. INTERVENTION Through an endonasal cartilage delivery approach to the ...

IMPORTANCE The contribution of columellar strut grafts (CSGs) to nasal tip support has not been determined via structural mechanics. Optimal graft dimensions have yet to be objectively determined. OBJECTIVES To use a finite element model (FEM) of the human nose to (1) determine the effect of the CSG on nasal tip support and (2) identify how suture placement contributes to tip support. DESIG...

In contrast to all other vertebrate cartilages, the major extracellular matrix protein of lamprey cartilages is not collagen. Instead, there exists a unique family of noncollagenous structural proteins, the significance of which is not completely understood. A custom-built uniaxial testing apparatus was used to quantify and compare equilibrium stress-relaxation behavior (equilibrium moduli, str...

We conducted a contemporary review covering advances and trends in primary and functional rhinoplasty as published during the past decade. Specifically, we reviewed studies supporting the evidence for functional rhinoplasty, nasal valve surgery, and septal reconstruction. In addition, key articles discussing cephalic malpositioning of the lower lateral cartilages and tip contouring are reviewed...

We present our experience of reconstruction of the nasal valve after iatrogenic collapse, and evaluate the feasibility and outcome of composite grafts. We selected all collapsed nasal valves that occurred after primary aesthetic rhinoplasties of the total number done at the University Tor Vergata in Rome. We excluded collapses that followed septoplasty for nasal deviation, reconstructions, and ...
