Postnasalis

Postnasalis is a term used in anatomy and medicine that refers to structures or phenomena located behind the nose. It can also be used to describe the posterior or nasal part of a specific anatomical region. For example, the postnasal space, also known as the nasopharynx, is the uppermost part of the pharynx, directly behind the nasal cavity. This space is crucial for airflow from the nose to the throat and plays a role in breathing and swallowing.

In a clinical context, "postnasalis" is often associated with postnasal drip. This condition occurs when excess mucus from the nasal passages or sinuses drips down the back of the throat. While postnasal drip is a common symptom, it can be caused by various factors, including allergies, infections, and irritants. The sensation of mucus dripping can lead to throat irritation, coughing, and a feeling of a lump in the throat.

The term might also appear in surgical descriptions, referring to a posterior approach to nasal structures. Understanding the precise location indicated by "postnasalis" is important for accurate diagnosis and treatment of conditions affecting the nasal and pharyngeal regions. Anatomical atlases and medical literature often utilize this term to delineate specific anatomical boundaries and pathways.
