What is the maxillary sinus?

The maxillary jaw bone has two (right and left) cavities, these cavities are usually filled with air and are the largest of the paranasal sinuses. Researchers believe that the paranasal sinuses help reduce the weight of the skull, allow for resonance, and warm inhaled air. 

Who needs a sinus lift?

Following tooth extraction, the maxillary sinuses tend to expand into the jaw bone. Sometimes the expansion of the maxillary sinus happens extensively to a degree that prevents implant placement. Dental implants are inserted into bone and when the amount of bone is not enough to hold an implant, a sinus lift is indicated. 

How is a sinus lift performed?

There are generally two main methods to performing sinus lifts

  • Internal sinus lift: This is almost always performed at the same time as implant placement, the cavity formed by implant surgery is used to access the floor of the maxillary sinus and help lift it.
  • External sinus lift: This is either performed as a separate procedure or concomitantly with implant placement. A separate access is utilized to lift the floor of the sinus cavity and allow for bone grafting. 

The choice of methods will depend on the amount of bone already available, the amount of augmentation necessary, the anatomy of the sinus, the number of implants to be placed, and patient factors. 

How would a sinus lift affect my sinuses?

A large number of patients are under the impression that sinus lift procedures are very invasive, and might affect their sinuses significantly. Usually, however, this is not the case. Discomfort in the first few days following surgery are not uncommon, but long term complication are very seldom encountered. Please speak to your dentist or Dr Sweidan about any concerns you have.
