Based on pathogen identification & ABX sensitivities. Topical vasoconstriction w/sympathomimetic amine. Pseudoephedrine 30mg q 4-6h.
What is the Management & Tx of Chronic Rhinitis?
Dx is based on demonstrating the causative microorganism by culture or biopsy. Tx consists of appropriate antimicrobial drugs.

Vasomotor rhinitis.
Rhinitis medicamentosa.
Allergic Rhinitis Labs;
Eosinophilla on nasal smear.
Skin test may identify responsible allergen.
Allergic Rhinitis Tx;
Avoid Allergen, Oral antihistamines & sympathomimetics, Phenylephrine or pseudoephedrine (can raise BP). 4% cromolyn by nasal spray 5.2mg tid or qid, Intranasal glucocorticoid spray (Rhinocort, Nasonex, Flonase) Allergen immunotherapy tx is advised if the allergen cannot be avoided, drug tx is poorly tolerated, or systemic glucocorticoids are needed.

Which facial bones are fractrued the most?
Nasal
What can a nasal fx affect?
The ascending processes of the maxilla & the septum.
Torn muccous membrane results in epistaxis.
What are the S/Sx of a nasal fx?
Blunt injury that causes bleeding from the nose; Deformity, Instability, Crepitus, Point tenderness, Most common is deviation of the dorsum to one side & depression of the nasal bone & ascending process of the maxilla on the other side.
Nasal Hemotoma PE;
Requires immediate medical attention! Septal cartilage has no blood supply & necrosis will occur. If bilateral cartilage will die in 24hrs.
Nasal Hemotoma Tx;
Surgical Drainage
Packing

Epistaxis Etiology;
Most nasal bleeding originates from a lexus of vessels in the anteroinferior septum (Kiesselbach's area)
Where do the majority of nosebleed originate?
The nasal septum & erupt when the thin nasal mucosa overlying a dilated septal vessel dries, scabs, & falls off.
What is the second most common cause of nosebleeds?
Trauma
A force sufficient to deform the nasal skeletal structures can cause mucosal disrution & bleeding anteriorly on the septum, laterally along the nasal walls.
