Sinus Membrane

The sinus membrane, also called the Schneiderian membrane, is a thin layer of tissue lining the maxillary sinuses, which are air-filled spaces in the cheekbone area above the upper teeth. It helps maintain the health and function of the sinus, which is involved in humidifying air and producing mucus. During dental procedures like sinus lifts or implant placements, this membrane is important because damaging it can cause complications. Maintaining the integrity of the sinus membrane is essential for sinus health and successful dental treatments involving the upper jaw.
