When thinking of smell, we usually consider it only as one of the five senses. Compared to the rest of senses, smell has been underestimated. By conducting a research, we will be able to discover how mistaken we are. The human sense of smell is more powerful than it's usually given credit for and plays a major role in human health and behavior than many experts in the field are aware of the sense of smell is present in our daily activities and, depending on the gender, perception may differ, as well as from the anatomical structure of the olfactory organ between genders to the stimulus of the odor. The fragrances determine our everyday food choices, places where we choose to spend with our life partner. Scents can determine our sexual behavior, in building infant-parent connection and create our habits as well. It can also warn us against the selection of food, persons, also death. In this case, the loss of smell can be related with an olfactory organ dysfunction, but as well can have an endocrine, genetic or psychical basis. The olfactory dysfunction can change our habits and basically our whole life. It is irrefutable that while talking about smell which we consider as one of the senses, we can talk about sensuality which broadly covers the relationship between smell and perception of reality. Sensuality in a general sense can be defined as the perception of the surrounding things through the senses, as sensory pleasure, and unlike sexuality, which can be translated as the reception of biological, psychological and physical stimuli. Aim of the study: Currently all of our senses are mostly well known. We are trying to consider the topic from many different sides to make ourselves more and more advanced. We are trying to unite a couple of subjects to prove that we can connect one with another to explore how advanced our organism is. In this research we are trying to look closely at the two different topics and glue them together. Trying to improve and update the connection between the sense of smell and sensuality. This is possible due to the relationship between the smell and the part of our brain responsible for memories and memory, i.e. the limbic system. In this way, we can process the aroma stimulus into memories, we associate smells with specific situations, places, people or things [1]. Therefore, the objectives we have in this study are the following: The nose as an olfactory organ and the anatomical differences as to structure; the olfactory system is strictly connected with the sense of smell; sex, as a gender, something that make us different from each other; physical and psychological disorders and influence of smell. Taking into consideration the amount of work and research on the sense of smell and the still uncertain issues related to it, it is certain how important it is for life and science to fully understand its properties. Over time, with the development of science and technology, there is an increasing wish to learn about such a complicated machine as the human body. Material and methods: In the first part of this research, we will gather all the information that is commonly available so far in the international bibliography, as well as the achievements and utilities obtained to date. Following we will analyse all the new concepts that exist on the topic of sense of smell in connection with sex and sensuality, also how the smell can change due to various disorders and try to summarise it based on the latest research.

Background: Children suffering from congenital facial malformations in underdeveloped countries are the main objective of the STMMIs with the aim of easing their lives. Clarós Foundation (CF) has carried out 115 missions worldwide with the aim, among others, of treating patients with this type of orofacial cleft malformation. We think that the experience we have acquired in this field can be transmitted to new NGOs institutions that want or wish to continue in this line. The optimization of the use of means and human resources, both from the NGO and the local health workers, will make it possible to achieve greater outcomes and results when applied in the development of Short Term Medical Mission International (STMMIs) missions. Material and Methods: We present the experience CF has acquired throughout the various STMMIs it has accomplished, during a period of 7 days each, specifying the details of its organization, patient selection, preparation of the surgery and its performance, in a well- organized manner to be fast, effective and safe in its results. During each of the 115 missions, the medical team has treated patients with this congenital pathology, in different proportions that go from 90% of the total cases to only 10% of the patients attended. The surgical techniques applied are those used in our medical center in Barcelona, which we may say, are the state-of-the-art surgical techniques used by the most advancedcenters. Results: A total of 1725 patientsunderwent surgery throughout 115 STMMIs, averageduration of 7 days each,115 STMMIs by 15 cases average. During this time 925 patients were operated for cleft lip and 800 patients for cleft palate. Male patients accounted for 58% and female for 42%. According to the age of the patients we found that the majority of cases were operated on babies 68.35% (1.179 neonatal period); 20.2% on children (300 cases) and (19.76%) adolescents (233 cases); and 1.10% adults in the 20-67 age range (13 cases). Of the total number of operated patients(1.725), there have been few immediate and late postoperative complications, but we estimate them at 11%. Conclusion: International cooperation between experienced NGOs and local medical teams turn out to be much more effective, less expensive and with better clinical results than those obtained without this collaboration. This organizational model can be very useful in order to know the details that these missions entail and apply them in your own activities.
