Schneiderian Membrane

The Schneiderian Membrane is a term used in dentistry to refer to the maxillary sinus membrane. It is an important structure in the field of dental implantology, particularly in sinus lift procedures. The membrane was named after Victor Schneider, a Swiss anatomist who first described it.

Anatomy

The Schneiderian Membrane lines the maxillary sinus, which is a pyramid-shaped cavity within the maxilla. The membrane is composed of a pseudostratified columnar epithelium, which includes goblet cells that produce mucus. This mucus is moved by cilia towards the ostium, a small opening that connects the sinus to the nasal cavity.

Clinical Significance

In dental implantology, the Schneiderian Membrane is often manipulated during a sinus lift procedure. This procedure is performed when there is insufficient bone height in the upper jaw, or the sinuses are too close to the jaw, for dental implants to be placed. The membrane is carefully lifted and bone graft material is placed beneath it, in the space where the sinus was. This allows for the creation of adequate bone structure for implant placement.

Complications

If the Schneiderian Membrane is perforated during a sinus lift procedure, it can lead to complications such as sinusitis, infection, or the failure of the dental implant. Therefore, careful surgical technique is required to avoid damaging the membrane.
