Pathological stages:

1. Stage I:    Redness.
2. Stage II:    Congestion of the mucosa.
3. Stage III:    Irritation.
4. Stage IV:    Rhinorrhea.

Sign and Symptoms: 60 % of the septal perforations are asymptomatic. The symptoms depend on the area of   perforation.
a) More anterior the perforation, more the symptoms.
b) Larger the perforation more the symptoms. Symptoms:

1. Whistling noise during inspiration.
2. Atrophic changes.
3. Bleeding.

Treatment:
Medical treatment:

1. Treat the root cause if any.
2. Apply cicatric cream to lesion.
3. Avoid trauma.
4. Improve general health.
5. Alkaline nasal douches.

Surgical treatment: Septal perforation repair surgery can be performed using either the “closed technique” or “open technique”. The advantages of the former consist in the fact that it does not leave any external scar. Many Surgeons prefer the “open” technique, as it offers a wider operating field, thus allowing better access to the superior and posterior margins of the perforation (especially in large and/or posterior perforations) and affording binocular vision.
