The nasal septum or the partition of the nose is a thin piece of cartilage and bone inside the nose between the right and left sides. It is about 7 cms long in adults. In some people this septum is bent into one or both sides of the nose, blocking it. Sometimes this is because of an injury to the nose, but sometimes it just grows that way.
There are also a couple of nasal cushions on either side wall of the nose called the inferior turbinates. When the nasal partition is bent to one side there is usually more room on the other side causing the cushion/turbinate to swell and block that side as well.
Mr. Dhanasekar routinely performs this surgery to straighten the nasal partition called Septoplasty or Submucous Resection. At the same time he will also address the swollen cushions and reduce their size. This procedure is called turbinate surgery or turbinate reduction. So collectively the septal and turbinate surgery markedly improves the nasal breathing.
