    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; auditive system and speech; single photon emission computed tomography; paranasal sinuses; ventilation; 133-xenon; chronic sinusitis; nose-sinus model; endoscopic sinus surgery; oxymetazoline; Otorhinolaryngology; Otorinolaryngologi; audiologi; hörsel- och talorganen; audiology;

    Sammanfattning : A noninvasive 133-xenon washout technique was used to evaluate the ventilation of the paranasal sinuses in healthy subjects and in patients with sinus disease. A mixture of air and 133-xenon is insufflated into the nasal cavities and passage into the sinuses is facilitated by a pressure increase created by letting the subjects inflate a balloon. LÄS MER

  3. 2. Mucosal regeneration following sinus surgery : an experimental study and clinical study

    Författare :Karin Forsgren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :chronic sinusitis; histopathology; Caldwell-Luc operation; sinus surgery; rabbit; regeneration; sinus mucosa; experimental sinusitis; microcirculation; blood flow; vasoreactivity; nerve regeneration; sympathetic; neuropeptide Y; tyrosine hydroxylase; immunocytochemistry;

    Sammanfattning : The investigations described in this thesis concerned functional and structural aspects of the regenerated sinus mucosa following sinus surgery. In a biopsy material collected pre- and postoperatively from patients with chronic maxillary sinusitis, randomized for treatment with either Functional Endoscopic Sinus Surgery (FESS) or the Caldwell-Luc procedure (CL), histological parameters were evaluated semi-quantitatively and correlated to endoscopic findings and patients' symptoms.

  4. 3. Prevalance of upper airway symptoms and aspects on treatment of nasal polyposis

    Författare :Petter Olsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Non-allergic rhinitis symptoms; prevalence; randomised controlled trial; nasal polyposis; functional endoscopic sinus surgery; mometasone furoate nasal spray; fluticasone propionate nasal drops; olfaction; health related quality of life; SF-36;

    Sammanfattning : Background: Non-allergic rhinitis is a disease that is often trivialised, leading to inadequate management and unnecessary costs. One of the most common types of severe non-allergic nasal inflammation is nasal polyposis. Nasal polyposis is associated with asthma. LÄS MER

  5. 4. Evaluation of medical and/or surgical treatment of anosmia/hyposmia in association with inflammatory disease of the upper airway

    Författare :Ebba Hedén Blomqvist; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Nasal polyposis; olfaction; medical surgical treatment; corticosteroids; scoring; staging; endoscopy; symptoms; anosmia; hyposmia; olfactory threshold test butanol ; computed tomography; sinuses; well-being; clinical; evaluation;

    Sammanfattning : Background: There is a lack of evidence-based, prospective studies in treatment of nasal polyposis. The correlations between symptoms, polyp scores and computed tomography (CT) scans have not been studied sufficiently. Little, if any, sense of smell is common in nasal inflammatory disease. LÄS MER
