4. Nasal septum
• Internal carotid system
Anterior ethmoidal artery
Posterior ethmoidal artery
• External carotid system
Sphenopalatine artery (branch of maxillary
artery) gives nasopalatine and posterior medial
nasal branches
Septal branch of greater palatine artery (branch
of maxillary artery)
Septal branch of superior labial artery (branch of
facial artery)
5.
6. Little’s area
It is situated in the anterior part of nasal septum, just
above the vestibule.
Four arteries- anterior ethmoidal, septal branch of
superior labial, septal branch of sphenopalatine and the
greater palatine, anastomose here to form a vascular
plexus called “Kiesselbach’s plexus”.
Usual site for epistaxis in children and young adults.
Retrocolumellar vein runs vertically downwards just
behind the columella, crosses the floor of nose and joins
venous plexus on the lateral nasal wall. This is a common
site of venous bleeding in young people.
7. Lateral wall
• Internal carotid system
Anterior ethmoidal artery
Posterior ethmoidal artery
• External carotid system
Posterior lateral nasal branches- from
Sphenopalatine artery
Greater palatine artery- from maxillary artery
Nasal branch of anterior superior dental- from
infraorbital branch of maxillary artery
Branches of facial artery to nasal vestibule

10. Woodruff’s area
This vascular area is situated under the
posterior end of inferior turbinate where
sphenopalatine artery anastomoses with
posterior pharyngeal artery.
Posterior epistaxis may occur in this area.
12. Local causes
Nose
1. Trauma- Finger nail trauma, injuries of nose, intranasal
surgery, fractures of middle third of face and base of
skull, hard-blowing of nose, violent sneeze.
2. Infections
Acute: viral rhinitis, nasal diphtheria, acute sinusitis.
Chronic: all crust-forming diseases, e.g. atrophic rhinitis,
rhinitis sicca, tuberculosis, syphilis septal perforation,
granulomatous lesion of the nose, e.g. rhinosporidosis.
13. Local causes…
3. Foreign bodies
Non-living: any neglected foreign body,
rhinolith.
Living: maggots, leeches.
4. Neoplasm of nose and paranasal sinuses.
Benign: haemangioma, papilloma.
Malignant: carcinoma or sarcoma.
5.Atmospheric changes. High altitudes, sudden
decompression (Caisson’s disease).
6. Deviated nasal septum.
15. General causes
1. Cardiovascular system- hypertension,
arteriosclerosis, mitral stenosis,
pregnancy (hypertension and hormonal).
2. Disorders of blood and blood vessels-
Aplastic anaemia, leukemia,
thrombocytopenic and vascular purpura,
haemophilia, Christmas disease, scurvy,
vitamin K deficiency, hereditary
haemorrhagic telangectasia.
3. Liver disease- hepatic cirrhosis
(deficiency of factor
16. General causes…
4.Kidney disease- chronic nephritis
5.Drugs- excessive use of salicylates and
other analgesics, anticoagulant therapy.
6.Mediastinal compression
7.Acute general infection- influenza,
measles, chickenpox, whooping cough,
rheumatic fever, infectious mononucleosis,
typhoid, pneumonia, malaria, dengue
fever.
8.Vicarious menstruation.
17. Sites of epistaxis
Little’s area
Above the level of middle turbinate
Below the level of middle turbinate
Posterior part of nasal cavity
Diffuse- both from septum and
lateral nasal wall.
Nasopharynx
18. Classification
Anterior epistaxis
More common
Mostly from Little’s area or
anterior part of lateral wall
Mostly occurs in children
or young adults
Mostly trauma
Usually mild, can be easily
controlled by local
pressure or anterior pack
Posterior epistaxis
Less common
Mostly from
posterosuperior part of
nasal cavity
After 40 years of age
Spontaneous; often due
to hypertension or
arteriosclerosis
Bleeding is severe,
requires hospitalization;
postnasal pack often
required
19. Management
In any case of epistaxis, it is important to know:
Mode of onset. Spontaneous or finger nail trauma.
Duration and frequency of bleeding.
Amount of blood loss.
Side of nose from where bleeding is occurring.
Whether bleeding is of anterior or posterior type.
Any known bleeding tendency in the patient or family.
History of known medical ailment (hypertension,
leukemias, mitral valve disease, cirrhosis, nephritis).
History of drug intake (analgesics, anticoagulants,
etc.).
20. First aid
Little’s area- pinching the nose with thumb
and index finger for about 5 minutes-
compression of vessels.
Trotter’s method- patient is made to sit,
leaning a little forward over a basin to spit
any blood, and breathe quietly from
mouth- cold compresses should be
applied to nose to cause reflex
vasoconstriction.
21. Cauterisation
Useful in anterior epistaxis.
The area is first anaesthetised and the
bleeding point cauterised with a bead of
silver nitrate or coagulated with
electrocautery.
22. Anterior nasal packing
If bleeding is profuse and/or the site of bleeding
is difficult to localise, anterior packing is done.
For this, a ribbon gauze soaked with liquid
paraffin is used.
About 1 metre gauze (2.5 cm wide in adults and
12 mm in children) is required for each nasal
cavity.
Pack can be removed after 24 hours if bleeding
has stopped.
23. Posterior nasal packing
It is required for patients bleeding
posteriorly into the throat.
A postnasal pack is first prepared by tying
three silk ties to a piece of gauze rolled
into the shape of a cone.
24. Endoscopic cautery
Posterior bleeding point can sometimes be
better located with an endoscope.
It can be coagulated with suction cautery.
Local anaesthesia with sedation may be
required.
25. Elevation of Mucoperichondrial flap and
SMR operation
In case of persistent or recurrent bleeds
from the septum, just elevation of
mucoperichondrial flap and then
repositioning it back helps to cause
fibrosis and constrict blood vessels.
SMR operation can be done to achieve
the same result or remove any septal spur
which is sometimes the cause of epistaxis.
26. Ligation of vessels
a) External carotid- above the origin of
superior thyroid artery.
b) Maxillary artery- approach is via
Caldwell-Luc operation.
c) Ethmoidal arteries- in anterosuperior
bleeding above the middle turbinate.
d) Sphenopalatine artery- TESPAL
(Transnasal Endoscopic
Sphenopalatine Artery Ligation)
27.
28. General measures in epistaxis
Make the patient sit up with a back rest and record any
blood loss taking place through spitting or vomiting.
Reassure the patient. Mild sedation should be given.
Keep check on pulse, BP and respiration.
Antibiotics may be given to prevent sinusitis, if pack is to
be kept beyond 24 hours.
Intermittent oxygen may be required in patients with
bilateral packs because of increased pulmonary
resistance from nasopulmonary reflex.
Investigate and treat the patient for any underlying local
or general cause.
29. Hereditary Haemorrhagic Telangectasia
It occurs on the anterior part of nasal
septum and is the cause of recurrent
bleeding.
It can be treated by using Argon, KTP or
Nd: YAG laser.
Some cases require septodermoplasty
where anterior part of septal mucosa is
excised and replaced by a split skin graft.
