How is sphenoid sinusitis diagnosed?
Paranasal sinus CT scan is a useful exam for the diagnosis of fungal sphenoid sinusitis (5–7).
Which routine projection will show all of the sinuses?
Lateral is the only projection to demonstrate all 4 paranasal sinuses (frontal, ethmoid, sphenoid, maxillary).
What is the best treatment for sphenoid sinusitis?
In general, start medical treatment of acute sphenoid sinusitis once the diagnosis is made. Institute antibiotics and decongestants for 24 hours, and if the patient does not improve over this time course, schedule surgical therapy. If the patient has evidence of complications, undertake urgent surgical decompression.
How is frontal sinusitis treated?
Viral infections are responsible for many cases of frontal sinusitis. The treatment plan usually involves rest, drinking plenty of fluids, and using over-the-counter nasal sprays or decongestants. If a bacterial infection is the underlying cause, a course of antibiotics can usually clear the infection.

Which routine projection is performed to best visualize the maxillary sinuses?
A radiograph of a PA (caldwell) projection for sinuses reveals that the petrous ridges are projected into the lower hald of the orbits and obscuring the ethmoid sinuses. The tech used a horizontal x-ray beam for the projection. The skull was positioned to place the OML at a 15 degree angle from the horizontal plane.
How do you treat maxillary sinusitis?
Rather, treatment is based on topical nasal decongestants and saline irrigation of the nasal cavity. Topical decongestants such as ephedrine or xylometazoline constrict the nasal lining, widening the paranasal sinus ostia, facilitating drainage by ciliary activity.
What is projection of the nasal tip?
In short, projection of the nasal tip refers to how far out the tip protrudes from the face as seen from the profile, or side, view. Some rhinoplasty patients mistakenly refer to this type of change as making the nose shorter when, in fact, this actually refers more to the rotational position of the nasal tip.
Is my nose tip over projected?
In reality, though, most experienced rhinoplasty experts will simply look at the nose and determine by gestalt if the nasal tip is over projected. This is much the same way rhinoplasty patients look at themselves and subjectively note that their nose is just too big for their face. Sure you can measure it using the Goode method.
What are the different types of nose tip deprojection?
Some rhinoplasty terms that refer to this type of nasal tip deprojection maneuver include: domal truncation, crural overlay, and vertical dome division. In other rhinoplasty patients, the entire lower lateral cartilage has to detached, moved and reattached to accomplish the desired change in tip projection.
What is the best way to deproject the nasal tip?
If this portion of the lower lateral cartilage is excessively prominent, very careful reduction of the dome can be undertaken to deproject the nasal tip. Some rhinoplasty terms that refer to this type of nasal tip deprojection maneuver include: domal truncation, crural overlay, and vertical dome division.
