Abstract
Introduction The importance of mucociliary clearance (MCC) for the respiratory system homeostasis is clear. Therefore, evaluating this defense mechanism is fundamental in scientific research and in the clinical practice of pulmonology and of associated areas. However, MCC evaluation has not been so usual due to the complexity of methods that use radiolabeled particles. Nevertheless, as an interesting alternative, there is the saccharin transit time (STT) test. This method is reproducible, simple to perform, noninvasive, does not demand high costs, and has been widely used in studies of nasal MCC. Although the STT test is widely used, there is still lack of a detailed description of its realization. Objective The present literature review aims to provide basic information related to the STT test and to present the findings of the previous studies that used this method, discussing variations in its execution, possible influences on the obtained results and limitations of the method, as well as to relate our experience with the use of STT in researches. Data Synthesis There are several factors that can alter the results obtained from STT tests, which would raise difficulties with proper interpretation and with the discussion of the results among different studies. Conclusions Saccharin transit time is a widely used method for the evaluation of nasal MCC, and therefore, the standardization related to the previous and concurrent to test orientations, and also its execution, become essential to improve its accuracy, and allow comparisons among different studies.

Abstract
BACKGROUND Turbinectomy, although a common procedure, is often accused of having a negative impact in all nasal functions. This study is the first in vivo study that evaluates objectively the effect of partial turbinectomy on nasal air-conditioning capacity. METHODS In total, 57 patients with prior partial inferior turbinectomy and 28 healthy controls were examined. Intranasal temperature and humidity values were measured at the level of the head of inferior and middle turbinate. Nasal patency was evaluated by means of acoustic rhinometry. The clinical assessment was completed with nasal endoscopy and the Nasal Obstruction Symptom Evaluation questionnaire for subjective evaluation of nasal patency. RESULTS Significant changes of temperature were found in both detection sites with 13% reduced heating capacity of the air at the level of the inferior and 19% at the level of the middle turbinate, respectively. No similar results were found for humidity measurements. No correlations were found between air-conditioning values and acoustic rhinometry results for both study groups. Nasal endoscopy revealed normal healing in all patients. No major complications were reported by the patients. Their subjective ratings of nasal obstruction were similar to healthy controls. CONCLUSION Partial turbinectomy seems to have a negative impact on intranasal air heating but not to humidification. This effect has no impact on clinical condition and subjective perception of surgical outcome.

Abstract
BACKGROUND In the presence of turbinate dysfunction, an inferior turbinectomy for persistent hypertrophy of bone and/or mucosa may be performed. We sought to explore anatomic feasibility of a transoral turbinectomy. METHODS After transoral inferior turbinectomy in 12 cadavers, average distances from the external nasal valve to inferior turbinate and from pyriform aperture to inferior turbinate were compared. Average "area of access" was calculated. Preoperative and postoperative nasal length, tip projection, and alar-base width were also compared. RESULTS Average distance from external nasal valve to inferior turbinate was 32.4 mm. Average distance from aperture to inferior turbinate was 2.4 mm (P < 0.0001). Average "areas of access" to nasal vault through the external nasal valve and mouth were 183.9 mm(2) and 243.6 mm(2) (P = 0.07), respectively. CONCLUSIONS The transoral approach provides a larger "area of access" to the turbinate, a statistically significant reduction of distance to target, no postoperative changes in nasal soft tissue, and easier instrumentation.
