The main blood supply is provided by the '''arterial ethmoid rete''', which is an anastamosis between the '''internal and external ethmoid arteries'''. A minor suply is provided by the caudal nasal branch of the '''sphenopalatine artery'''.
The main blood supply is provided by the '''arterial ethmoid rete''', which is an anastamosis between the '''internal and external ethmoid arteries'''. A minor suply is provided by the caudal nasal branch of the '''sphenopalatine artery'''.
The conchal sinuses include the dorsal, ventral and middle. Each conchus is divided into two compartments, rostral and caudal, by a complete septum.
*Dorsal conchal sinus: This is formed by the caudal compartment of the concha
*Ventral conchal sinus: This is formed by the caudal compartment of the ventral concha
*Middle conchal sinus: Lies within the greater ethmoturbinate, not clinically significant
