Development

The ethmoid and maxillary sinuses are usually present at birth
The sphenoid develops 2-3 years after birth
The frontal sinus is occasionally present at birth but usually appears around 2 years
They all continue to develop until puberty
Lined with mucoperiosteum and pseudostratified columnar ciliated epithelium
All drain lymph to submandibular nodes except sphenoid and posterior ethmoidal which drain to retropharyngeal nodes
All drain into middle meatus except sphenoid sinus (sphenoethmoidal recess) and posterior ethmoidal air cells (superior meatus)

Maxillary sinus

Largest
Located in body of maxilla
Connects to the nose via an opening in its base piercing the hiatus semilunaris
Drains to middle meatus
Nerve supply: infraorbital nerve (continuation of maxillary nerve), anterior, middle and posterior superior alveolar nerves
Arterial supply: anterior and posterior superior alveolar branches of the infraorbital and maxillary arteries

Honeycomb of air cells
Separated from orbit by lamina papyracea
Anterior and middle groups drain into middle meatus
Posterior group drains into superior meatus
Nerve supply: anterior and posterior ethmoidal nerves and branches of pterygopalatine ganglion
Arterial supply: anterior and posterior ethmoidal arteries and sphenopalatine artery
