The paranasal sinuses(commonly referred to as sinus) are complex air cell pockets under the cheek(maxillary), under the forehead (frontal), between the eyes( ethmoid) and at the back of the nose ( sphenoid).
All the sinuses have a very small opening, usually 2 mm, which can be easily blocked, even a short few days of viral infection of the sinus lining. If left untreated, it results to a longer term problem of chronic sinusitis.
The treatment for sinus is to unblock the sinus, whether by medicine or surgery. Due to the complexity of the anatomy of the sinuses, it is unfortunately common to learn about recurrence of sinus blockage and this recurrent infection.
Repeated infections usually mean there is a Sinus cell that is blockage and thus infection.
When patients have infection after medicine and sinus Surgery, it is usually necessary to repeat the sinus scan
with image guidance surgical option.
There are other sinus related conditions such as inverting papilloma, nasal wall tumors, recurrent polyps and
epiphora(excessive tearing). These conditions is often only treatable by either open or endoscopic nasal surgery.
