Salivary Gland Cancers: A Survey through History, Classifications and Managements
In this chapter, we are going to discuss about salivary glands cancers, their clinical manifestations and categories, pathogenesis, diagnosis and treatment. We will go through details in each part in both clinical and surgical aspects based on recently prominent published studies and research in prestigious journals. After a short review on clinical features, epidemiology, pathogenesis, diagnosis and treatment, we will show staging and tumor node metastasis (TNM) classification of major salivary gland tumors and also basic principles of approach to salivary gland cancers. A little will be explained about basic surgical procedures for removal of cancers and benign tumors.

Cochlear Implants: An Excursus into the Technologies and Clinical Applications
Hearing loss causes severe alterations in social function and daily communications. Cochlear device implantation (CDI) is the only beneficiary method for auditory rehabilitation in patients with severe to profound sensorineural hearing loss (SNHL). Regarding a report in 2014, over 300,000 people had received cochlear implants throughout the world since December 2012 among which about 60,000 were adults and 40,000 were children in the United States. In this chapter, we discuss the history, origin, mechanism of action, and type of cochlear implants, as well as method of surgery and complications.

Congenital Anomalies of the Thymus
The thymus, a retrosternal lymphoid tissue, develops from the third and fourth pharyngeal pouches like the parathyroid glands at the sixth week of gestational age. The thymus is usually located in the anterior mediastinum, although it can be found anywhere in the thymopharyngeal path. The thymus has a bilobed or quadrilateral shape; however, it can be found in other shapes. Limited information is available about the precise epidemiology of thymic congenital anomalies. Since these anomalies are not symptomatic, it may be more common than the available reports. There are various reports available about the prevalence of thymic diseases and anomalies ranging from 4.45 to 30%. In this chapter we tried to have a review on epidemiology, definition, and management of congenital anomalies of the thymus.
