    OBJECTIVES: Nasal peak inspiratory flow (NPIF) is a practical and affordable tool that measures maximum inspiratory flow rate through both nostrils. Although NPIF values for healthy controls and patients appear to differ considerably, a generally expected value for populations with and without nasal obstruction has yet to be established. The aim of this systematic review and meta-analysis was to determine the mean NPIF value in populations with and without nasal obstruction.

    METHODS: Medline (1946-) and Embase (1947-) were searched until July 1, 2017. A search strategy was used to identify studies that reported NPIF values for defined healthy or disease states. All studies providing original data were included. The study population was defined as having either normal nasal breathing or nasal obstruction. A meta-analysis of the mean data was presented in forest plots, and data were presented as mean (95% confidence interval [CI]).

    RESULTS: The search yielded 1,526 studies, of which 29 were included. The included studies involved 1,634 subjects with normal nasal breathing and 817 subjects with nasal obstruction. The mean NPIF value for populations with normal nasal breathing was 138.4 (95% CI: 127.9-148.8) L/min. The mean value for populations with nasal obstruction was 97.5 (95% CI: 86.1-108.8) L/min.

    CONCLUSIONS: Current evidence confirms a difference between mean NPIF values of populations with and without nasal obstruction. The mean value of subjects with no nasal obstruction is 138.4 L/min, and the mean value of nasally obstructed populations is 97.5 L/min. Prospective studies adopting a standardized procedure are required to further assess normative NPIF values. Laryngoscope, 131:260-267, 2021.

    OBJECTIVE: Patients suffering from persistent inferior turbinates hypertrophy refractory to medical treatments require surgical intervention where the main aim is symptomatic relief without any complications. Extraturbinoplasty is one of the preferred procedures for turbinate reduction due to its efficacy in freeing up nasal space by removing the obstructing soft tissue and bone while preserving the turbinate mucosa. We sought to evaluate the effectiveness and safety of microdebrider assisted turbinoplasty (MAT) and coblation assisted turbinoplasty (CAT) performed as an extraturbinoplasty procedure.

    METHODS: A prospective randomized comparative trial was conducted among patients with bilateral nasal blockage secondary to inferior turbinates hypertrophy. Patients were randomly assigned to MAT or CAT. An extraturbinal medial flap turbinoplasty was performed for both techniques. Symptom assessment was based on the visual analogue score for nasal obstruction, sneezing, rhinorrhea, headache and hyposmia. Turbinate size, edema and secretions were assessed by nasoendoscopic examination. The assessments were done preoperatively, at 1st postoperative week, 2nd and 3rd postoperative months. Postoperative morbidity like pain, bleeding, crusting and synechiae were documented. The clinical outcomes of both techniques were analyzed using repeated measures ANOVA.

    RESULTS: A total of 33 participants were recruited, 17 patients randomized for MAT and 16 patients for CAT. Nasal obstruction, discharge, sneezing, headache and hyposmia significantly reduced from 1st week until 3 months for both procedures. Similar significant reductions were seen for turbinate size, edema and secretions. However, there was no significant difference in symptoms and turbinate size reduction were seen between both groups at the first postoperative week, 2nd and 3rd postoperative months. There was significant longer operating time for CAT when compared to MAT (p = 0.001). The postoperative complications of bleeding, crusting and synechiae did not occur in both groups.

    CONCLUSION: Both MAT and CAT were equally effective in improving nasal symptoms and achieving turbinate size reduction in patients with inferior turbinate hypertrophy. Both MAT and CAT offer maximal relieve in patients experiencing inferior turbinates hypertrophy by removing the hypertrophied soft tissue together with the turbinate bone without any complications.

    Nasal obstruction is a subjective complaint in patients with nasal disease. The ability to quantitate the nasal ventilation dysfunction would be useful for making the appropriate choice of nasal disease management. This cross-sectional study comprised of 200 adult subjects. They underwent assessment of relevant symptoms, nasal examination and investigations before undergoing active anterior rhinomanometry (AAR) assessment. A group of 88 normal subjects and 112 patients with nasal disease were included. The mean total nasal air resistance (NAR) was significantly higher in patients with nasal disease (0.33 Pa/cm(3)/s) as compared to normal subjects (0.24 Pa/cm(3)/s). There was no significant difference in total NAR between patients with symptoms of nasal obstruction and those without the symptoms (p = 0.42). It is concluded that AAR is a sensitive but not a specific tool for the detection of abnormalities in NAR and it failed to relate to the symptom of nasal obstruction.
