Following tooth extraction and oroantral fistula has developed that did not close spontaneously. The patient visited the doctor several weeks later when an Aspergillus mycosis of the sinus had developed....
Rhinolith
If an inert foreign body remains within the nasal cavity for many years, it may become surrounded by a calcified coating. Such a "nasal stone" is termed a rhinolith. Rhinoliths have a whitish...

Normal Frontal Recess [left]
This is a view into a normal left frontal recess taken with a 30° telescope. To the right the lateral face of the middle turbinate is visible. The uncinate process is seen fading superiorly. Between44...
The Superior Meatus and Sphenoethmoidal Recess
The superior meatus lies lateral to the superior turbinate. This is a view into the superior meatus underneath a well developed right superior terminate. The ostia of the ethmoidal clefts and cell openings...

Eustachian Tube Orifice [swallowing]
The opening and closing of the eustachian tube orifice can be observed as the patient swallows or performs a Valsalva manoeuvre.
Postoperative Frontal Sinus Recess
A close-up view into the frontal recess area following endoscopic sinus surgery. The unobstructive passage into the frontal sinus can be clearly seen in the 12 o'clock position.

The Sphenoethmoidal Recess [right]
A right sphenoethmoidal recess. Note the superior and supreme turbinates as well as the sphenoid sinus ostium. There is some thickened, nonpurulent secretions issuing from the posterior ethmoid and sphenoid...

The Sphenoid Sinus Ostium [right]
The sphenoid sinus ostium is located in the posteriorosuperior portion of the nasal cavity just lateral to the insertion of the posteriorosuperior portion of the nasal septum into the anterior wall of...
