What is HRV? HRV (Heart Rate Variability) is the measurement of the variation in time (in milliseconds) between two consecutive heartbeats. A high HRV reflects the autonomic nervous system's ability to switch flexibly between "stress" mode (sympathetic) and "recovery" mode (parasympathetic). Therefore, HRV is an excellent indicator of the overall stress level our body is […]

There is no excerpt because this is a protected post.

This article summarizes my recently published study on the link between EN6Q scores and a whole range of data from my fluid simulations.

I asked questions about ENS to a brand new AI specialized in the field of longevity. It bases its answers on a database of 4,000 scientific studies.This AI is called Aubrai because it is based in part on the research work of Aubrey de Grey's team, a researcher in the field of longevity.Here are some […]

The Context of Empty Nose Syndrome (ENS) In people with Empty Nose Syndrome (ENS), the sensation of airflow is often absent or altered, largely due to a loss of wall shear stress (WSS), the mechanical force exerted by air as it flows along the nasal walls, which is sensed by receptors in the mucosa. This […]

First of all, what are VOCs? Volatile organic compounds (VOCs) are chemical substances that easily evaporate into the air at room temperature. They are found in many everyday products such as solvents, adhesives, paints, cleaning products, furniture, and electronics. Some VOCs can irritate the airways, damage and dry out the nasal mucosa. In people with […]

There are two humidity values: Relative Humidity (RH) and Absolute Humidity (AH).The one you see everywhere on hygrometers or weather apps is relative humidity. Relative humidity is the percentage of water vapor present in the air compared to the maximum amount the air can hold at a given temperature. For example, 50% relative humidity means […]

How to report concerns with the medical devices used in turbinate procedures in the United States

I might have found out some really important stuff for getting ENS recognized. It might be a bit complex, but please bear with me. Ask your questions, I will try to edit the post to make it more understandable. The short version first I saw a new doctor. He diagnosed that everyday activities give me […]

I started working on the design and manufacturing of nasal plugs which will aim to increase nasal resistance, increase airflow velocity and therefore increase WSS and ultimately nasal sensation

Understanding ENS SymptomsENS symptoms can vary, and if you have specific questions about pain, airflow sensations, mucus, or other symptoms, please consult a healthcare professional. While I don't personally experience these symptoms, I'm here to provide information and support. The Causes of ENS SymptomsENS often results from structural changes in the nose during surgery, altering […]

Learn from other patients how to ease your symptoms. Gain quick relief with proven tools, methods, and medications.

We get many questions of people asking whether they have ENS. ENS6Q The "The Empty Nose Syndrome 6-Item Questionnaire (ENS6Q)" is a scientifically validated diagnostic aid and checks for the symptoms that makes ENS distinct from others nose diseases. If you are asking yourself, if you might have ENS, you can take this simple self-test to get […]

Nasal obstruction and its treatments Nasal obstruction is caused by turbinates inflammation or other diseases that can swell turbinates or a deviated septum. Nowadays, the first line of treatment to reduce nasal obstruction is by medication and if that doesn’t help, surgical procedures are considered. Here is a list of the common interventions: Temporary medical […]

Introduction For decades, teams of researchers around the world have been trying to find ways to extend lifespan and slow aging. Recently billions of dollars are injected into the research and some wealthy people are trying to do all they can to slow their aging process.Bryan Johnson is one of them, he spends 2 millions […]

In the precedent article, I performed a virtual surgery by adding implants. I redid a virtual surgery keeping the previous implants and adding one on the left side.

In this article, I will compare many parameters before and after the virtual implants to see if there are improvements.

Introduction First of all, what is Flowgy? Flowgy is a software dedicated for CFD of the nasal cavity with tools for virtual surgery. In this article, I will compare the results that I got with my industrial software (Onshape and Simscale) and the results with Flowgy. I would like to thank Pr Manuel Burgos for […]

Introduction As planned I designed virtual implants in my nasal cavity in order to improve airflow distribution and decrease cross-sectional area to tend toward a healthy nose. Virtual implants placement In red are the virtual implants that I designed, you can see that I added a lateral wall implant behind the existing one on the […]

Introduction Finally, I was able to make a 3d model of my nasal cavity usable with a CFD software. For those who don't know what is CFD, it just mean Computational Fluid Dynamics which is the study of fluids, in our case the air.I took 15 l/min for the flow rate and I did not […]

I designed a simplified 3d model of a nasal cavity (just one side) to test different scenarios such as adding an implant. You can see that I grouped the superior turbinate and the middle turbinate in order to simplify the model. I need a simple model because it is better to make future geometry change. […]

First of all, I found this study that compares the cross-sectional area of a control group with an ENS group. I found this interesting so I do the same for myself, and here are the results. We can see that there is no doubt that my nasal cavity (in blue) is more empty than the […]

Go to https://www.prusa3d.com/, click on software and select your OS. Install the prusa slicer.This software is a "slicer", it is used to prepare the 3d model to be 3d printed, to transform the STL file into a G-code readable for the 3d printer.But in our case, we will just use this software to edit the […]

In this tutorial, I will explain how to turn your DICOM data pulled from your CT-SCAN into a 3d printable file. Go to https://www.slicer.org/ download the software and install it.Open it and click on import DICOM files, search the directory of your DICOM files and click on import. Click on show DICOM database, click on […]

The first one is hydrolized collagen, some studies tend to prove that it can improve skin health, hydration, thickness etc ... Exemple this study. Hydrolyzed collagen is a type of collagen with low molecular weight in order to be better absorbed by the body and reach the skin and other organs. So I ask myself […]

I try to know how to rebuild the nasal cavity after an inferior turbinectomy, where to add volume in priority ? Some ENTs think that the head of the turbinates is the most important because it is where it's easiest to add resistance. And they often think that nasal resistance is the most important parameter […]

I just would like to share with you a device that I made. It is a syringe pump. Often during the night, our nose becomes dry, so we can use a humidifier. It works but has its limits. So I have designed this syringe pump in order to inject physiologic serum into the nasal cavities […]

In this post, I would like to see which place is the best for an implant in my left nasal cavity. On this side, there is a remaining inferior turbinate. So I would like to know if it is better to implant cartilage on a lateral wall or if an implant in the turbinate is […]

In this post, I will try to find which implant shape is the best to get closer to the natural turbinate. Special thanks to Andrea Magelli to give me this idea. Below it is my case of my right nasale cavity before turbinectomy (yellow), after turbinectomy (green), after my cartilage implant (blue), and after a […]

In the previous article I showed you a device for visualize your breathing. In this article I will show you how to use it as a sleep breathing recorder in order to detect hypopnea and apnea. For it, I have just connected the microcontroller arduino to the PC with a USB cable and use two […]

Introduction Currently, a researcher from Ohio university drive an ENS study which consist of breathing visualization in order to tell to the brain that even we don't feel airflow we are currently breathing air.The technique of breathing consist of breath near a mirror for seen the fog created by our breathing.I directly thought that it […]

Empty Nose Syndrome can affect your sleep in some ways.Some people wake up after one or two hours because the nose becomes dry.But I think that the first reason ENS affects our sleep is because it creates central sleep apnea. So what is central sleep apnea ? It is a respiratory problem which occurs when […]

While in the previous post I explained why ENS can affect the sleep, in this post I will explain how a CPAP machine can help you to sleep better. There are two types of machines, the CPAP which is normally designed for obstructive sleep apnea and servo ventilation which is designed for central sleep apnea. […]
