Abstract
Background: The gold standard for auricle reconstruction is currently performed with autologous costal cartilage. This process is done at about nine years of age, but it leads to thoracic deformity, reported in up to 70% of the patients using a Computed Tomography (CT) scanner.
Objective: The present study aims to determine if this deformity has functional implications for the patients.
Methods: 54 patients were clinically evaluated and subjected to spirometry at least one year after the surgery.
Results: Four cases had moderate pulmonary restriction, while seven had mild lung restriction. A total of 20.3% of the patients showed pulmonary restriction. The new results are particularly crucial for patients with preoperative (pre-op) ventilatory disease.
Conclusion: In patients with thoracic deformity diagnosed by clinic exploration, spirometric abnormalities occur in up to 20.3%; when stratifying the risk by gender, the risk is only significant for women older than 15 years old.


Keywords: Auricle reconstruction, Respiratory function alterations, Thoracic deformity, Autologous auricle reconstruction sequelae, Microtia.

 

Introduction
Microtia (small ear) is a congenital deformity secondary to an alteration during embryonic development characterized by the partially or entirely underdeveloped pinna.1 The earliest reports of auricle reconstruction are described in the Sushruta Samhita, an ancient text, 900 BC. In 1930, Pierce reported a post-traumatic repair using costal cartilage.2 The previous findings paved the way for Tanzer, who pioneered modern costal cartilage reconstruction.3 Since then, the sixth to the tenth costal cartilages have been used in auricle reconstruction techniques.

 Sustainable Development: Reality Or Myth? Since the United Nations Environment Conference in Stockholm (1972), the concept of sustainable development has steadily made its way among individual scientists and international organizations. The apotheosis of this development was the adoption by the United Nations in 2015 of the 17 Sustainable Development Goals. However, many scientists and politicians were skeptical about the concept of sustainable development, since the results of implementing sustainable development in different countries were far from expected. Many decisions taken at the level of the UN and other international organizations turned out to be unfulfilled. In my opinion, as well as some other Russian scientists, the concept of sustainable development is an unrealistic project, it is a myth, although it is very positive and humane. Sustainable development goals can be achieved only by the most economically developed countries entering the era of post-industrialism. In...

 How to Treat Cancer Properly Cancer is one of the deadliest diseases in the world, chemotherapy is effective under some conditions, but has too heavy side effects, and it is not effective to a considerable proportion of cases while the side effects are often life-threatening, drugs (not unhealthy addictive drugs mentioned in reference four, the drug in reference four only mean those makes people addictive but does no good to health, destroying health quickly) are not always available to improve the condition. However, sport is a potential treatment that is effective to cancer before the cancer is disseminated, this gets little attention but is true both in theory and practice. The physical activities that have moderate intensity and duration should have devastating effects on cancer cells, they make the body hot and reduce the nutritional resources that cancer cells can get, also renew the proteins in the body and improve one’s mood, cancer cells are hard to live when one is activ...

 From Bronchial Asthma to Tuberculosis: Unravelling the Cytokine-Macrophage Axis in Diverse Diseases Cytokines, tiny proteins secreted by cells, play a critical role in mediating communication and interactions between cells. They also function as immunomodulating agents, adjusting immune responses. When released into the bloodstream or tissues, cytokines bind to specific receptors on target immune cells, triggering cellular responses. Cytokines are implicated in various diseases, including asthma, COPD, HIV infection, and multiple sclerosis. This review delves into the intricate interplay between cytokines and macrophages, focusing on their roles in inflammation and the immune response. Macrophages, which are scavenger cells of the immune system, exhibit remarkable heterogeneity, reside in diverse tissues, and play crucial roles in both innate and acquired immunity. They can be activated for proinflammatory or anti-inflammatory functions, contributing to tissue destruction or regen...
