OBJECTIVE Superior semicircular canal dehiscence (SSCD) represents a rare condition that may be associated to some particular symptoms as vertigo, autophony, and Tullio phenomenon. In those patients who present severe symptoms surgical treatment is required. Middle fossa craniotomy and transmastoid approaches are both described. Concerning repairing techniques, plugging and/or resurfacing are t...

A brief technique to place a cement plug on top of a polyethylene is presented. This technique has helped the authors obtain better cement mantles when they are plugging the canal in total hip replacement.

Preexisting wells and well bores are high-permeability pathways through the crust, and as such present zones of elevated risk to CO2 storage projects. Although current well closure and abandonment technology appears sufficient to contain CO2 at most sites, individual wells may suffer from a variety of factors that limit their integrity, including improper cementation, improper plugging, overpre...

In bronchiectasis the morphological determinants of (marginal) fluctuations in pulmonary function tests are uncertain. The aim of the present study was to evaluate serial computed tomography (CT) changes in relation to pulmonary function trends in patients with bronchiectasis. The relationships between pulmonary function indices and CT scans in 48 adult patients with bronchiectasis were evaluat...

The article is devoted to the issue of a low sweep efficiency in heterogeneous terrigenous reservoirs containing remaining oil. Water plugging operations that redirect injection fluid flows into unswept zones, are one approach enhancing oil recovery these reservoirs. commonly used chemical reagents treatments acrylate polymer solutions. solutions must reach target water-saturated zones and form...
