What is a good Haller index?
A normal chest has a Haller index of 2 or less. A Haller index between 2 and 3.2 is considered a mild deformity; between 3.2 and 3.5, moderate.; 3.5 or greater, a severe deformity.
How do I reduce Haller index?
Some authors have found that both radiographic- and CT-calculated Haller indices are strongly correlated and thus recommend the use of chest radiography instead of CT to minimize the radiation exposure 2. The Haller index is affected by the vertebral level at which it is measured and is largest cranially 3.
How do I check my Haller index?
The Haller index of severity should be calculated by measuring the inner width of the chest at the lowest level of the PEX defect, and dividing it by the anterior-posterior distance (between the posterior surface of the sternum and the anterior surface of the spine) again at the lowest level of the defect.
What does the Haller index measure?
The Haller index is described as the ratio of the thoracic width to the thoracic height within the thoracic cage used in the assessment of pectus excavatum (Haller et al. 1987). This ratio is calculated from measurements from a single axial CT image per patient that is not referenced to a vertebral level.
Is the Nuss procedure worth it?
Our results demonstrate that the Nuss procedure is safe and can be performed with excellent results in adults, both in the short term and in the long term. The improved quality of life and patients’ satisfaction with cosmetic results remained high in the long-term follow-up, 10 years after the surgical procedure.
Does concave chest get worse?
For many people with pectus excavatum, the only sign or symptom is a slight indentation in their chests. In some people, the depth of the indentation worsens in early adolescence and can continue to worsen into adulthood. In severe cases of pectus excavatum, the breastbone may compress the lungs and heart.
Does Ludwig have pectus excavatum?
English comedian and presenter Josh Widdicombe and YouTuber/streamer Ludwig Ahgren are known to have this condition. Zachary Woods is another popular American actor that has pectus excavatum, which is noticeable in his shirtless scene in an episode of The Office (Season 8, episode 12).
How long is recovery from Nuss procedure?
What is the typical recovery following a Nuss operation? Every patient is different but on average it takes about 4 to 6 weeks to recover from the surgery though it will take up to 12 weeks before you return to full and normal physical activities including sports.
What is the best age for Nuss procedure?
The procedure is typically performed from age 10 up until the age of 19. The Nuss procedure involves a concave stainless steel bar that is slipped under the sternum with the assistance of a scope (small camera) using two small incisions on each side of the chest.
Does pectus excavatum affect life expectancy?
There is no evidence that pectus excavatum limits life expectancy or causes progressive damage to the heart and lungs over time. It is not uncommon for individuals to develop more symptoms over time.
What is Haller index in CT scan?
Haller index. Giuseppe Oppo and Dr Ahmad Yahia et al. The Haller index (HI), also known as the pectus index, is a simple mathematical way to assess and describe the chest cage on CT of the thorax and is used in the detection of pectus excavatum, as well as preoperative and postoperative assessment 1,5.
Which technique is used to measure the Haller index?
All three techniques for Haller Index measurement are used. However, a chest radiography is proven to be just as effective as a CT Scan. In simple terms, the Haller Index measures how wide (transverse diameter) the chest is, compared to its depth (anterior-posterior diameter).
What is the Haller index of normal chest radiography?
Some authors have found that both radiographic- (plain film) and CT-calculated Haller indices are strongly correlated and thus recommend the use of chest radiography instead of CT to minimize the radiation exposure 2. The following values are used: normal chest: <2.0. mild excavatum: 2.0-3.2.
What is the best alternative to the Haller index?
It is scientifically proven the 3D Optical Imaging to be a great alternative to the Haller Index. Nowadays a simple chest radiograph or a CT scan are the two most commonly used ways to measure the Haller Index. Even though most surgeons agree on its usefulness, they also agree it can give the wrong picture about the seriousness of the deformity.
