METODEN

Ultramax ultraljudsapparaterna är sinuitdiagnostik apparater för att upptäcka bihåleinflammation (i sinus maxillaris och sinus frontalis). Apparaten skickar ultraljud mot benet bakom bihålen och bakvägg. Eko som reflekteras tillbaka visas på bildskärmen. En frisk bihåla, med bara luft i, reflekterar eko ljudet tillbaks direkt. Den använda ultraljudsfrekvensen (3 MHz) fortplantar sig väl genom både mjuk vävnad och ben men inte genom luft.


Ultraljudsundersökningar har bevisat att hälften av de kliniskt diagnostiserade bihåleinflammationerna (AMS) är fel. Användning av Ultramax apparaterna förbättrar följdaktligen sinuit diagnos och minskar onödiga läkarbesök och antiobioter. Reliabilitet är 80-90% i jämförelse med spolning.


Finland är banbrytare I sinuit diagnos med ultraljud: över 50% av sinuit misstanke undersöks med ultraljud.


Flesta röntgenundersökningar av sinus kan substitueras med Ultramax ultraljudsapparaterna som ger ofarlig strålning och är följaktligen en säker metod att användas också med barn över tre år och gravida kvinnor.


Flera akademiska och vetenskapliga studier från de sista 30 åren visar att ultraljud är ett effektivt och säkert sätt att diagnostisera bihåleinflammation.

    Ultrasound device helps in ruling out maxillary sinus fluid in acute rhinosinusitis: how we do it.

    " ...Only half of patients with a clinical diagnosis of AMS have sinusitis in ultrasound examination. Meaning that half of the patients were prescribed unnecessary antibiotics."

    Acute rhinosinusitis in primary care: a comparison of symptoms, signs, ultrasound, and radiography.

    "...The sensitivity of ultrasound compared to radiography was 92% and specificity was 95% when results were calculated per patients as unit of analysis. With practice and teaching primary care physicians can perform sinus ultrasound as accurately as specialists. Symptoms and clinical examination were not reliable in AMS diagnosis. If the criterion for AMS diagnosis were fluid in maxillary sinuses in ultrasound instead of clinical impression, the number of antibiotic prescriptions would be reduced by half in primary care."

    Validity of ultrasonography in diagnosis of acute maxillary sinusitis.

    ...The high specificity of ultrasonography indicates that a positive ultrasound finding can be regarded as evidence of maxillary sinusitis... Active use of ultrasonography would substantially decrease the need for radiological imaging of the sinuses and also help reduce unnecessary antibiotic treatment in primary care."

    Ultrasonography as a method of examination of the frontal sinus.

    "This prospective study was performed to evaluate the reliability of ultrasonography for the detection of fluid and mucosal swelling in the frontal sinus. The evaluation was based on a comparison of the preoperative ultrasonographic results with the surgical findings in 27 frontal sinuses. Ultrasonography was found to be a reliable method for the demonstration or exclusion of mucosal swelling and accumulated fluid (sensitivity 92%; specificity 93%)."
