    Prognostic value of anterior rhinomanometry in diode laser turbinoplasty.

    Arch Otolaryngol Head Neck Surg 2010 Oct;136(10):1015-9
    Department of Otorhinolaryngology, Friedrich-Schiller-Universität, Lessingstraße 2, D-07743 Jena, Germany.
    Objective: To identify objective criteria predicting the success of diode laser-assisted turbinoplasty.

    Design: Prospective before-and-after trial with follow-up of 8 weeks.

    Setting: Outpatient department of a tertiary referral center.

    Patients: Forty-one patients with nasal obstruction caused by hyperplastic inferior nasal turbinates.

    Intervention: Active anterior rhinomanometry with and without decongestion was used to assess the patients both before and after diode laser-assisted turbinate surgery. Surgery was performed under local anesthesia in "contact mode" using a continuous diode laser. In addition, a questionnaire assessed the subjective postoperative benefit.

    Main Outcome Measures: Presurgical effect of topical decongestion was correlated with postoperative improvement of nasal airflow and patients' subjective satisfaction.

    Results: Turbinoplasty significantly improved the mean (SD) nasal airflow by 37.1% (52.4%) (95% confidence interval [CI], 20.6%-53.7%), from 509.8 (189.2) cm³/s (95% CI, 450.1-569.5) to 660.9 (285.4) cm³/s (95% CI, 570.8-751.0) (P < .001). There was no significant correlation between patients' subjective satisfaction and improvement of nasal airflow postoperatively (r(s) = -0.01; P = .93). There was a strong correlation between the presurgical effect of topical decongestion and the improvement of nasal airflow by surgery (r(s) = 0.42; P = .01). The correlation was even stronger when the absolute values were adjusted by the preoperative nasal airflow baseline (r(s) = 0.55; P = .01).

    Conclusions: Rhinomanometry with topical decongestion has a high predictive value for the objective outcome of diode laser-assisted turbinoplasty. Thus, performing a rhinomanometry with topical decongestion and calculating the relative spread of decongestion can help to estimate the patients' benefit from diode laser-assisted turbinate surgery.

    Comparison of long term results after Ho:YAG and diode laser treatment of hyperplastic inferior nasal turbinates.
    Lasers Surg Med 2007 Apr;39(4):324-31
    Laser-Research Laboratory at the LIFE-Center, Ludwig-Maximilians University, 81377 Munich, Germany.
    Background And Objective: Various laser systems have been used to reduce the volume of hyperplastic inferior nasal turbinates during the last 25 years. Although there are many studies reporting the clinical results immediately after laser treatment, there are only a few describing long-term results. Therefore, a clinical study was performed to assess and to compare the long-term outcome of both endonasal Ho:YAG and endonasal diode laser-assisted turbinate surgery. Read More

    Department of Otorhinolaryngology, Head and Neck Surgery; Charité-University Medicine Berlin, Berlin, Germany.
    Background: The purpose of this study was to evaluate long-term outcomes of an outpatient-based diode laser inferior turbinate reduction (ITR) in therapy-refractory rhinitis medicamentosa (RM).

    Methods: In a prospective clinical investigation, 42 consecutive RM patients underwent videoendoscopic ITR with a diode laser after topical anesthetic preparation. Intra- and perioperative details were recorded including the occurrence of bleeding, crusting, pain, or discomfort. Read More
