Epistaxis, or nosebleeds, are common and usually caused by local trauma or irritation to the nasal mucosa. The nasal septum and Kiesselbach's plexus are frequent bleeding sites. Epistaxis can be anterior or posterior depending on the location of bleeding. Initial management involves resuscitation, arresting the bleeding through local measures like anterior nasal packing, and treating any underlying causes. Refractory epistaxis may require arterial embolization, laser cauterization, or ligation of arteries supplying the nasal mucosa like the sphenopalatine artery. Hospitalization is needed for posterior epistaxis or severe anterior bleeding.

Bleeding from inside the nose is called epistaxis
Fairly common and is seen in all age groups.
“Epistaxis refers to nose bleed or hemorrhage from the nose”.
It‘s mostly commonly originates in the anterior portion of the nasal cavity.
A hemorrhage from the nose, referred to as epistaxis, is caused by the rupture of tiny, distended vessels in the mucous membrane of any area of the nose.
Most commonly, the site is the anterior septum, where three major blood vessels enter the nasal cavity:
(1) the anterior ethmoidal artery on the forward part of the roof (Kesselbach’s plexus)
(2) the sphenopalatine artery in the posterosuperior region, and
(3) the internal maxillary branches (the plexus of veins located at the back of the lateral wall under the inferior turbinate).

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

10. Little’s area
•It is situated in the anterior inferior part of nasal septum, just
above the vestibule.
•1 Anterior ethmoidal
•2 Septal branch of superior labial
•3 Septal branch of Sphenopalatine
•4 The greater palatine
•This area is exposed to the drying effect of inspiratory
current and to finger nail trauma, and is the usual site for
epistaxis in children and young adults.
Kiesselbach’s plexus
11. • Woodruff’s plexus – inferior to posterior end of
inferior turbinate.
• 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
12. Nasal cavity – principal location of anastomoses in H &N
Vessels run submucosal
vessels supplying the middle and inferior turbinate – bony
conduit/tunnels and have periarterial fibrous venous cuff.
Ant ethmoidal artery - mesentery attached to skull base,
between ethmoid fovea and lamina papyracea.
Following embolisation/ligation – compensatory anastomosis
flow via facial artery - rebleed
APPLIED ANATOMY
13. CAUSES OF EPISTAXIS :
A) Local (nose or nasopharynx).
B) General
C) Idiopathic
17. 6) Mediastinal compression. Tumours of mediastinum
(raised venous pressure in the nose).
7) Acute general infection.
8) Vicarious menstruation (epistaxis occurring at the time of
menstruation).
C) Idiopathic :
• Many times the cause of epistaxis is not clear.
18. SITES OF EPISTAXIS :
1) Little’s area ( 90% ).
2) Above the level of middle turbinate.
3) Below the level of middle turbinate.

26. First aid :
•Trotter’s method
•Cold compresses - reflex vasoconstriction.
Cauterisation :
•In anterior epistaxis when bleeding point has been located.
•The area is first anaesthetised and the bleeding point
cauterised with a bead of silver nitrate or coagulated with
electrocautery.
30. Anterior nasal packing :
•If bleeding is profuse and/or the site of bleeding is difficult
to localise, anterior packing should be done.
•Ribbon gauze soaked with liquid paraffin.
•One or both cavities may need to be packed.
•Can be removed after 24 hours if bleeding has stopped.
•If kept for 2 to 3 days; systemic antibiotics given to prevent
sinus infection and toxic shock syndrome.
34. Posterior nasal packing :
• Method
• Patients requiring postnasal pack always be hospitalised.
• Folley’s catheter can also be used.
• Nasal balloons are also available.
.

36. OTHER OPTIONS
Rapid Rhino anterior balloon tampon
carboxymethylcellulose, a hydrocolloid material, acts as
platelet aggregator and forms a lubricant upon contact with
water. The Rapid Rhino balloon has a cuff that is inflated by
air. The hydrocolloid preserves the newly-formed clot
during tampon removal.
37.
38.
39. Elevation of mucoperichondrial flap and SMR
operation :
• In case of persistent or recurrent bleeds from the
septum, elevation of mucoperichondrial flap and
then repositioning it helps to cause fibrosis and
constrict blood vessels.
• SMR operation remove any septal spur
45. General Measures in Epistaxis :
1) The patient put in semi recumbent position and record
any blood loss through spitting or vomiting.
2) Reassure the patient. Mild sedation.
3) Keep check on pulse, BP and respiration.
4) Maintain haemodynamics: Blood transfusion.
5) Antibiotics to prevent sinusitis, if pack is be kept beyond
24 hours.
6) Investigate and treat the patient for any underlying local
or general cause.
46. Commonly seen condition
Most of the patients respond to conservative
therapy
Follow the management protocol for best
results
Endoscopic methods are very accurate
Arterial ligations are last options in cases of
intractable epistaxis
Newer methods have excellent outcome but
expensive
