Abstract:
Secondary middle turbinate (SMT), a rare variation of the nasal cavity, is a bony projection covered by soft tissue that arises from the lateral nasal wall. It is almost always bilateral and usually projects superomedially without any ostiomeatal unit obstruction. Herein, we report a case of bilateral inferomedially projecting secondary middle turbinates, one of which is pneumatised and hypertrophied, resembling a large ethmoid bulla extending into the middle meatus. The recognition of this variation is important since it may predispose to inflammatory sinus disease, by narrowing the ostiomeatal unit.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
