Fisiología Nasal

Rinomanometria Rhinomanometría cuantifica el flujo aéreo

nasal durante respiración nasal exclusiva. (Nasal resistance measurement)

Acoustic rhinometry.

Rhinomanometry and acoustic rhinometry can beused clinically to evaluate nasal patency in anumber of situations. Either test may be used fora general evaluation of nasal airflow and to

compare premorbid conditions with changes thatmay occur after medical or surgical therapy.Additionally, these tests can compare nasalpassages for medical or surgical planning.

22781169,22703359, 8882551312



Otros examenes Radiologic imaging with CT or MRI also can

assess the cross-sectional area of nasalpassages (see the eMedicine article CT Scan,Nasal Cavity).

The saccharin test evaluates ciliary function bymeasuring the time it takes for a drop ofsaccharin to be tasted in the back of the throatwhen applied to the anterior tip of the inferior

turbinate.

Otros examenes olfato University of Pennsylvania Smell Identification

Test (UPSIT)es el test del olfato mas conocido.

.The UPSIT is a 40-item scratch-and-sniff testand is highly validated by age and sex.

Recent research into exhaled nitric oxidesuggests that in the future, these measurementsmay prove valuable as non-invasive objectivetools for the assessment and management of

normal nasal physiology and nasal and sinusdisorders.[3]

Anomalías de la fisiología nasal Nitric oxide

Low NO concentrations were reported in certain

diseases, such as primary ciliary dyskinesia, cystic

fibrosis, and acute and chronic maxillary sinusitis,whereas high concentrations were detected in

upper airway infection, allergic rhinitis, and nasal

polyposis.

Correlaciones Clìnicas

Anosmia - Absence of smell sensation

Hyposmia - Decreased sensation

Dysosmia - Distortion of smell sensation Cacosmia - Sensation of a bad or foul smell

Parosmia - Sensation of smell in the absence ofappropriate stimulus

22781169,22703359, 8882551322



Síndromes Clínicas Kallmann syndrome (ie, hypogonadism with

anosmia)

Foster Kennedy syndrome (ie, papilledema,unilateral anosmia, and optic atrophy usually

associated with an olfactory groove meningioma).

Partial complex epilepsy with a mesial temporalfocus includes an aura of foul-smelling odors(termed uncinate fits) that occur before seizure

onset, emphasizing presumed origination at theuncus.

Sindromes clínicas Olfactory dysfunction

is associated withearly Parkinsondisease and with

otherneurodegenerativedisorders, such asAlzheimer disease

and Huntingtonchorea.[3] Anassociation also existsbetween abnormal

olfactory identification

Head trauma leading tofracture of the cribriformplate may causecerebrospinal fluid (CSF)rhinorrhea and a potential for

meningitis. Paranasal sinusendoscopy may lead toviolation of the cribriformplate and potential infectiouscomplications. Olfactorystructures also can beinjured during craniotomiesinvolving the anterior cranialbase or from subarachnoidhemorrhage, which maydisrupt the fine fibers of the

olfactory nerve. 13/04/2012

Liquidos Cerebro Espinal

Rinorrea liquido claro Promptly complete evaluation and treatment of

clear rhinorrhea in the patient in whom leakage ofCSF is suspected. Initial testing of fluid forglucose suggests CSF but is not confirmatory.

Presence of beta transferrin is a more sensitiveindicator of CSF rhinorrhea. Computedtomography (CT) scanning with cisternography orradionuclide scans can be used to detect the site

of CSF leakage from the anterior cranial fossa.Repair of leaks at the level of the cribriform platemay be achieved from the intracranial approach,intranasal (endoscopic) approach, or both,

depending on the nature of the defect. 13/04/2012
