Animal noses
\"Noses come in all kinds of shapes and sizes that are just right for its particular animal host. Not only do most animals use their noses to breathe but for many animals, the sense of smell helps them find food, a mate, or even to know when danger is near! Following Animal Tails, Animal Eyes, Animal Mouths (NSTA/CBC Outstanding Trade Science Award), and Animal Legs, Mary Holland continues her photographic Animal Anatomy and Adaptations series by exploring many different animal noses and how those noses help the animals survive in their habitats\"-- Provided by publisher.

Risk factors for intraoperative saddle nose deformity in septoplasty patients
Introduction
Septoplasty is one of the most common otolaryngologic procedures. Previous studies have reported that the overall rate of significant change in cosmetic appearance of the nose after septoplasty ranged from 0.4 to 3.4%, and saddle nose was the most commonly cited deformity. In this study, we evaluated the risk factors for intraoperative saddle nose in a group of septoplasty patients.
Methods
This case–control study (1:2 case:control) was conducted based on retrospective chart review. Intraoperative saddle nose was observed in 108 (5.1%) of 2106 patients who underwent septoplasty in our center between January 2008 and December 2017. The control group consisted of 216 randomly selected, hospital-matched septoplasty patients who had no intraoperative saddle nose deformity in the same period. The demographic data, preoperative endoscopic findings, and surgical procedures of the two groups were analyzed to identify possible risk factors of intraoperative saddle nose deformity.
Results
The mean ages of the two groups were 34.8 years (saddle group) and 33.2 years (control group). In multivariate logistic regression analysis, clinical risk factors associated with intraoperative saddle nose were female gender (OR 3.39; 95% CI 1.76–6.54;
p
< 0.01), severe caudal septal deviation (OR 2.22; 95% CI 1.30–3.79;
p
= 0.003), and intraoperative finding of septal cartilage fracture (OR 3.96; 95% CI 1.92–8.19;
p
< 0.01).
Conclusions
Severe caudal septal deviation, intraoperative fracture of septal cartilage, and female gender were risk factors for intraoperative saddle nose deformity in our study population.

Semi-wrapping lateral cartilage to a square edged strut perpendicularly to prevent collapse in external nasal valve dysfunction: pseudodome technique
Objectives: During inhalation through the nose, the weakness of lateral cartilage may cause the collapse of nasal vestibule and sidewall, causing the complaint of difficult breathing through the nose. We aimed to support the lateral cartilage with a square edged strut to resolve this problem.Methods: We described a technique in 8 cases (5 males, 3 females). In this technique the lateral cartilage is semi wrapped from the underside to a square edged strut, and arched to outside with an open approach rhinoplasty. As it was only a physical support and did not create a new canting up through the skin, we named this maneuver as pseudodome technique. Results: All patients experienced relief of symptoms and no complications observed. The reinforcement effect of the strut was effective in preventing collapse of the nasal alar sidewall as well as did not cause contour irregularities. Conclusions: Pseudodome technique can be performed for acquired or congenital nasal sidewall collapse caused by lower lateral cartilage structural weaknesses successfully.

Artificial Olfactory Neuron for an In‐Sensor Neuromorphic Nose
A neuromorphic module of an electronic nose (E‐nose) is demonstrated by hybridizing a chemoresistive gas sensor made of a semiconductor metal oxide (SMO) and a single transistor neuron (1T‐neuron) made of a metal‐oxide‐semiconductor field‐effect transistor (MOSFET). By mimicking a biological olfactory neuron, it simultaneously detects a gas and encoded spike signals for in‐sensor neuromorphic functioning. It identifies an odor source by analyzing the complicated mixed signals using a spiking neural network (SNN). The proposed E‐nose does not require conversion circuits, which are essential for processing the sensory signals between the sensor array and processors in the conventional bulky E‐nose. In addition, they do not have to include a central processing unit (CPU) and memory, which are required for von Neumann computing. The spike transmission of the biological olfactory system, which is known to be the main factor for reducing power consumption, is realized with the SNN for power savings compared to the conventional E‐nose with a deep neural network (DNN). Therefore, the proposed neuromorphic E‐nose is promising for application to Internet of Things (IoT), which demands a highly scalable and energy‐efficient system. As a practical example, it is employed as an electronic sommelier by classifying different types of wines. A neuromorphic module of an electronic nose (E‐nose) is demonstrated by hybridizing a semiconductor metal oxide (SMO) and a single transistor neuron (1T‐neuron). By mimicking a biological olfactory neuron, it can perform gas detection and spike encoding simultaneously for in‐sensor neuromorphic functioning. It is helpful to realize a highly scalable and energy‐efficient E‐nose for mobile gas sensors and IoT applications.

Are nasal steroids effective in children with adenoid hypertrophy?
Objectives: Chronic nasal obstruction is a common disease of childhood. Adenotonsillar hypertrophy plays an important role in obstructive sleep apnea. The topical use of the aerosolized forms of corticosteroids therefore seems the most appropriate route to decrease systemic side effects. The aim of our study is to demonstrate the effect of topical mometasone furoate especially on the adenoid volume in patients without any allergic story.Methods: The study group consisting of 30 males and 25 females was administered topical nasal mometasone furoate steroid treatment. The 20 patients were in the control group where saline solution (0.9% NaCl) treatment was administered consisted of 12 males and 8 females. Nasopharyngeal X-rays before treatment revealed that 25 patients were Grade 2 and 30 patients were Grade 3 according to the Fujioka method. Results: Flexible endoscopy performed before the treatment revealed that 20 patients were Grade 2, 11 patients were Grade 3 and 24 patients were Grade 4. Nasal endoscopies performed after 6 weeks of intranasal topical steroid therapy revealed that 45 patients were Grade 1 and 10 patients were Grade 2. A statistically significant difference was present between endoscopic grades before and after treatment (p < 0.0001). Nasal endoscopies performed after 6 weeks in control group receiving saline solution treatment revealed Grade 2 in 7 patients, Grade 3 in 10 patients and Grade 4 in 3 patients. There was no statistically significant difference between in the prior and later grades of the control group (p = 0.3125). Conclusions: We believe that the use of intranasal steroids (mometasone furoate) for 6 weeks in patients with pediatric chronic nasal obstruction due to adenoid hypertrophy may be an effective treatment modality in alleviating symptoms and decreasing adenoid volume without causing systemic side effects.
