Table 1 Mladina classification of septal deviation

MLADINA classification

 Type I

The unilateral crest which does not disturb the function of the nasal valve. Maintains normal physiological valve angle

 Type II

The unilateral vertical septal ridge in the valve region that touches the nasal valve, thus reducing the physiological valve angle

 Type III

The unilateral vertical ridge that is located more deeply in the nasal cavity, opposite the head of the middle turbinate

 Type IV

Bilateral deformity consisting of type II on one side and type III on the other

 Type V

An almost horizontal septal spur that sticks laterally and deeply into the nasal cavity. The opposite side of the nasal septum is straight

 Type VI

Massive unilateral sulcus runs through the caudal-ventral part of the septum, while on the other side is a ridge and accompanying asymmetry of the nasal cavity

 Type VII

Variable combination of the previous types
