|
viral rhinitis
|
|
presence of purulent nasal discharge suggests what type of infection:
|
bacterial infection
|
|
there is no curative treatment for viral rhinitis: T or F
|
T
|
|
Supportive measures such as decongestants (pseudoephedrine [Sudafed], 30 to 60 mg Q 4 to 6 hours) may provide some relief of rhinorrhea and nasal obstruction.
|
viral rhinitis
|
|
Nasal sprays such as oxymetazoline (Afrin) or phenylephrine (Neo-Synephrine) are also helpful and are rapidly effective.
They should not be used for more than a few days at a time, since chronic use leads to a rebound congestion that is often worse than the original symptoms. |
viral rhinits
|
|
Episodic rhinorrhea of clear, watery discharge; sneezing; and obstruction of the nasal passages; with lacrimation and pruritis of the conjunctiva, nasal mucosa, and oropharynx, are the hallmark symptoms
|
allergic rhinits
|
|
nasal mucosa is pale and boggy
|
allergic rhinitis
|
|
“Allergic shiners” (a bluish discoloration below the eyes) may be present.
|
allergic rhinitis
|
|
a “nasal crease” (a horizontal line just distal to the tip of the nose as a result of wiping the nose in an upward motion) may also be seen.
|
allergic rhinitis
|
|
Treatment includes avoidance of any known allergens, and the use of antihistamines, cromolyn sodium (NasoCrom), nasal or systemic steroids, nasal saline drops, and immunotherapy.
|
allergic rhinitis
|
|
consists of bogginess of the nasal mucosa associated with a complaint of stuffiness and rhinorrhea.
The symptoms are labile and can clear quickly. Treatment is avoidance of the irritant. (similar to walking through perfume section) |
vasomotor rhinitis
|
|
chronic nasal stuffiness that results in rebound congestion secondary to the overuse of nasal decongestant sprays such as Afrin and Neo-Synephrine.
Treatment requires complete cessation of the sprays. This triggers a period of severe nasal congestion that usually lasts 1 to 2 weeks |
rhinitis medicamentosa
|
|
Topical intranasal corticosteroids such as fluticasone (Flonase), 2 sprays in each nostril QD, or a short tapering dose of oral prednisone may help during the process of withdrawal. (won't work as quickly or as effectively as nasal decongestant sprays - pt must be aware of this, and this can be frustrating)
|
rhinitis medicamentosa
|
|
is a bacterial infection involving inflammation of any the paranasal sinuses as a result of impaired mucociliary clearance and obstruction of secretions, usually following a viral infection of the upper respiratory tract
|
sinusitis
|
|
Physical exam reveals secretions that are purulent green or yellow, and occasionally, visible swelling over a sinus.
|
sinusitis
|
|
the most common form of sinusitis:
|
maxillary sinusitis
|
|
It is associated with pain and pressure over the cheeks, retroocular pain, temporal headache that is exacerbated by leaning forward, maxillary dental pain, purulent rhinorrhea, and conjunctivitis.
|
sinusitis
|
|
_______ sinusitis can cause a severe headache above the eyes, which is exacerbated by assuming a supine position and alleviated with an upright position.
It also causes pain and tenderness of the forehead, most easily elicited by palpation of the orbital roof just below the medial end of the eyebrow; a low-grade fever; upper lid edema; and rhinorrhea. |
frontal
|
|
______ sinusitis is more common in children than adults.
It produces a low-grade fever and periorbital, retroorbital, frontal, or medial canthal pain that is worse when supine, coughing, or straining |
ethmoid
|
|
__________ cellulitis may be present with sinusits and pt needs to be admitted
|
periorbital
|
|
With sphenoid sinusitis (which is relatively rare), patients classically complain of a deep-seated retroocular pain and headache at the occiput, vertex of the skull, or behind the eye which is worse when supine or bending forward, and better with the head upright.
-It requires a CT scan for diagnosis. -When acute, this is a medical emergency, and all patients should be admitted to the hospital! |
sphenoid
|
|
With ________ sinusitis, suspect nasal foreign bodies (especially in children) and cancer
|
unilateral
|
|
Recurrent sinusitis in children may indicate ______ fibrosis or Kartageners syndrome (complete situs inversus associated with bronchiectasis and chronic sinusitis associated with ciliary dysmotility and impaired ciliary mucous transport in the respiratory epithelium).
|
cystic
|
|
Important complications of sinusitis include osteomyelitis and periorbital and orbital _______.
|
cellulitis
|
|
Common bacterial isolates are Streptococcus pneumoniae, Haemophilus influenzae, Streptococcus pyogenes, Staphylococcus pyogenes, and Moraxella catarrhalis.
|
sinusitis
|
|
Imaging modalities include plain radiographs and CT.
The radiographic hallmarks of acute _________ are: air-fluid levels, soft tissue density (opacification) without bone destruction, and mucosal thickening > 5 mm. CT is the most sensitive and specific technique, and allows for better delineation of the sphenoid and ethmoid sinuses. |
sinusitis
|
|
Water Posteroanterior View
|
Best view for visualizing the maxillary sinus
|
|
Caldwell Posteroanterior View
|
Most useful for visualizing the frontal and ethmoid sinuses
|
|
Chamberlain-Towne View
|
Most useful for visualizing the frontal sinuses and also the occipital bone
|
|
Submental-Vertex Base View
|
Valuable for visualizing the ethmoid and sphenoid sinuses, as well as the skull base. *CT may be better.
|
|
For treating __________________, amoxicillin, macrolides, and trimethoprim-sulfamethoxazole are appropriate agents.
Refractory cases or immunocompromised patients require broader spectrum antibiotics such as amoxicillin with clavulanate (Augmentin) and second or third generation cephalosporins. Treatment is usually for 10 to 14 days, but up to 3 weeks may be necessary. Decongestants reduce local edema, increase air movement within the sinuses, and decrease local secretions. Humidified air, steam, or nasal saline sprays also facilitate drainage. Patients should be strongly encouraged to stop smoking. (slows mucociliary action) |
acute bacterial sinusitis
|
|
pale, edematous, mucosally covered masses commonly seen in patients with allergic rhinitis.
|
nasal polyps
|
|
They may result in chronic nasal obstruction and a diminished sense of smell.
|
nasal polyps
|
|
The presence of in children should suggest the possibility of cystic fibrosi(as does recurrent sinusitis).
|
nasal polyps
|
|
Initial treatment with nasal steroids for 1 to 3 months is usually successful for small ______ and may reduce the need for surgery.
When medical management is unsuccessful, _______ should be removed surgically. |
nasal polyps
|
|
Bleeding from the ____________, a vascular plexus on the anteroinferior nasal septum, is by far the most common type of epistaxis encountered.
|
Kiesselbach plexus
|
|
Predisposing factors include nasal trauma (nose picking, foreign bodies, forceful blowing), rhinitis, drying of the nasal mucosa from low humidity, alcohol use, and antiplatelet medications.
|
epitaxis
|
|
Most cases of _______________ can be successfully treated by direct pressure on the bleeding site.
This is accomplished by applying pressure to the nasal alae for at least 10 minutes with the patient in the sitting position to reduce venous pressure, and leaning forward to reduce the swallowing of blood. |
anterior epistaxis
|
|
Short-acting topical nasal decongestant sprays such as phenylephrine (Neo-Synephrine), which act as vasoconstrictors, may also be helpful.
|
epitaxis
|
|
The nasal speculum should be inserted into the vestibule and spread in an __________ direction - do not spread laterally!
|
inferior to superior
|
|
For epitaxis, topical 4% _______ can applied by way of a cotton pledget serves both as an anesthetic agent and a vasoconstrictor.
|
cocaine
|
|
When visible, the bleeding site may be cauterized with ____________ or electrocautery. (need to clear the clot because the clot encourages more bleeding, have pt blow clot out)
Occasionally, a site of bleeding may be inaccessible to direct control, or attempts at direct control may be unsuccessful. |
silver nitrate
|
|
Anterior nasal packing should remain in place for at least ___ hours, and for no more than __ days.
|
48 hours, 4 days
|
|
After nasal packing, a systemic _________ should be administered since the packing acts as a foreign body occluding the sinuses.
-Amoxicillin is a good choice. |
antibiotic
|
|
A small percentage of cases of epistaxis involve bleeding in the posterior nasal cavity (_____________ plexus), most commonly behind the inferior and middle turbinates.
-The bleeding may compromise the airway and requires both posterior and anterior packing. |
Woodruff's
|
|
Because this is uncomfortable for the patient, and because it requires oxygen supplementation to prevent hypoxia, hospitalization and ENT consultation are required.
-The packing usually remains in place for 5 to 7 days. |
epitaxis with bleeding in the post nasal cavity (Woodruff's plexus)
|
|
the most frequently fractured bone in the body
|
nasal pyramid
|
|
Epistaxis and nasal pain are common, as are soft tissue hematomas (“black eyes”).
|
nasal fracture
|
|
Treatment is aimed at maintaining long-term nasal airway patency and nasal aesthetics.
|
nasal fracture
|
|
In the presence of marked nasal swelling, it is best to wait several days for the edema to subside before attempting reduction.
Persistent functional or cosmetic defects may be repaired by delayed reconstructive nasal surgery. |
nasal fracture
|
|
Intranasal examination should be performed in all cases of nasal trauma to rule out ____________, which appears as a bluish, grapelike mass on the nasal septum.
|
septal hematoma
|
|
An untreated _____________ will result in loss of the nasal cartilage with resultant “saddle-nose deformity”.
|
septal hematoma
|
|
hematomas may also cause infection, abscess, and aseptic necrosis, followed by absorption of the septal cartilage, resulting in septal perforation.
|
septal hematoma
|
|
Treatment consists of incision and drainage via an intranasal septal mucosal incision.
It is important to be sure that both sides of the septal cartilage are adequately drained. Packing is placed to prevent reaccumulation. Antibiotic prophylaxis is recommended. |
