Your ENT Doctor may have ordered a CT Scan of the siuses for some reason. Shown is a labelled animation of the CT scan of one of my patients depicting normal as well as abnormal structures.

Shown is the CT scan of the Nose and Sinuses

The scan shows

Nose

Nasal septum- a bony- crtilaginous structure that divides the 2 halves of the nose

maxillary sinuses-are air filled sinuses[ black in colour if normal]on either side of the nose

Ethmoid Sinuses- located between the eyes in the upper part  of the nose

&Turbinates-The turbinates are fleshy masses on either side of the nose.There are 3 pairs of turbnates- superior,middle and inferior.

Abnormalities in this CT Scan:

In this particular patient there is enlargement[ hyprtrophy] of the iferior turbinates on both sides producing nose block

The middle turbinates are also abnormal - they are curved in an abnormal direction and are termed paradoxical middle turbinates.

The nasal septum which divides the 2 halves of the nose has a prominent abnormality called a nasal septal spur which is a projection of the septum in an abnormal fashion.This can produce narrowing of the air passages, turbulence of air flow and contact with the turbinates. This can produce various effects such as:-

Nose block

Nose bleeds [Epistaxis]

Headache

Facial pain

This patient underwent successful endoscopic septoplasty and endoscopic turbinate surgery.
