Chemical senses such as odor, taste and appearance are directly related with appetite. Understanding the relation between appetite and flavor is getting more important due to increasing number of obese patients worldwide. The literature on the studies investigating the change in olfactory abilities and gustatory sensitivity mostly performed using food-related odors and tastes rather than standardized tests were developed to study olfaction and gustation. Therefore, results are inconsistent and the relationship between olfactory and gustatory sensitivity with respect to the actual state of human satiety is still not completely understood. Here, for the first time in literature, we investigated the change in both olfactory abilities and gustatory sensitivity in hunger and in satiety using 123 subjects (37 men, 86 women; mean age 31.4 years, age range 21–41 years). The standardized Sniffin’ Sticks Extended Test and Taste Strips were used for olfactory testing and gustatory sensitivity, respectively. TDI score (range 1–48) was calculated as the collective scores of odor threshold (T), odor discrimination (D) and odor identification (I). The evaluation was performed in two successive days where the hunger state of test subjects was confirmed by blood glucose test strips (mean blood glucose level 90.0 ± 5.6 mg/dl in hunger and 131.4 ± 8.1 mg/dl in satiety). The results indicated statistically significant decrease in olfaction in satiety compared to hunger (mean TDI 39.3 ± 1.1 in hunger, 37.4 ± 1.1 in satiety, p < 0.001). The comparison of gustatory sensitivity indicated significantly higher sensitivity to sweet, sour and salty in hunger (p < 0.001), but significantly higher sensitivity to bitter tastant in satiety (p < 0.001). With this prospective study, we were able to show that both olfactory abilities and gustatory sensitivity were affected by hunger state. © 2015, Springer-Verlag Berlin Heidelberg. Source

Background Several grafting materials have been used in revision rhinoplasty to correct overresected dorsum. Autologous materials are generally preferred, but have the drawbacks of additional surgical time and donor site morbidity. Tutoplast-processed fascia lata (TPFL) offers a commercially available alternative to autologous fascia grafts. We reviewed the results of 42 revision rhinoplasty procedures that used TPFL with or without autologous cartilage to correct overresected dorsum. Methods Forty-two patients with overresected dorsum underwent revision rhinoplasty with multilayered TPFL at our institution between 2005 and 2012. Saddle nose deformities were classified into one of three types, according to severity. Surgical results were evaluated as excellent, good, or fair by an otolaryngologist who compared preoperative photographs with pictures taken at final follow-up. Surgical complications were analyzed. Results Of the 42 patients who underwent rhinoplasty with multilayered TPFL, 36 were treated with TPFL alone, while autologous cartilage was used concurrently in six. Twenty-six (62 %) of the patients showed excellent aesthetic improvement, 11 (26 %) showed good improvement, and five (12 %) showed fair improvement. There were no major complications. Minor complications included edema in six patients, major resorption in three, and minimal resorption in nine. Patients with mild or moderate saddle nose deformity had better surgical results than those with more severe deformity. Conclusions There are many possible methods to correct overresected dorsum. Multilayer TPFL is safe alternative to autologous rib cartilage grafts. Level of Evidence: Level IV, therapeutic study. © 2015, Springer-Verlag Berlin Heidelberg. Source
