FRONTONASAL DUCTS Meaning and
Definition
-
Frontonasal ducts refer to narrow passages that connect the frontal sinus (a paired air-filled cavity located in the forehead) with the nasal cavity. These ducts play an essential role in the respiratory system by ensuring the proper drainage and ventilation of the frontal sinus.
The frontonasal ducts are situated within the bony structure of the skull, specifically in the area where the ethmoid bone and frontal bone meet. These thin and delicate ducts serve as a conduit for the transportation of mucus, air, and other fluids between the frontal sinus and the nasal cavity.
The main function of the frontonasal ducts is to maintain the health of the sinuses. They facilitate the passage of mucus, which lines the sinuses and helps to trap and remove debris, allergens, and bacteria. By allowing the exchange of air and mucus between the frontal sinus and the nasal cavity, the frontonasal ducts also contribute to the regulation of air pressure within the sinuses.
When the frontonasal ducts become blocked or obstructed, usually due to inflammation, infection, or nasal polyps, it can lead to a condition called frontal sinusitis. This condition is characterized by symptoms such as pain and pressure in the forehead, facial tenderness, nasal congestion, and nasal discharge. Proper treatment and management of frontal sinusitis may involve medical interventions like antibiotics, decongestants, nasal irrigation, or in severe cases, surgical intervention to reopen or widen the obstructed frontonasal ducts.

Etymology of FRONTONASAL DUCTS
The word "frontonasal" is composed of two parts: "fronto-" and "nasal".
"Fronto-" is derived from the Latin word "frons", which means "forehead" or "front". It is often used as a prefix to indicate something related to the frontal region or forehead.
"Nasal" is derived from the Latin word "nasus", meaning "nose". It pertains to anything related to the nose or nasal passages.
"Duct" comes from the Latin word "ductus", which means "to lead" or "to convey". In anatomy, it refers to a tube-like structure that allows the passage of a substance, such as fluid or air.
Therefore, "frontonasal ducts" refer to the ducts or channels that connect or lead from the frontal or forehead region to the nasal passages.
