Communication between the maxillary sinus and oral cavity is a common complication in oral surgery. It results mainly from maxillary premolar and molar extractions when the sinus floor is close to the tooth apex. It can also occur after an infection involving the maxillary teeth, invasion of the sinus cavity by a cyst or carcinoma, trauma, the Caldwell-Luc operation, or other dentoalveolar or implant procedures. Openings smaller than 2 mm may heal spontaneously, whereas larger openings require surgical treatment. An oroantral fistula (OAF) may develop as a complication of dental extractions, as a result of infection, or as sequelae of radiation therapy, trauma, and removal of maxillary cysts or tumors. Various techniques have been examined for the closure of oroantral communications. However, the most common question is how to provide better healing of the defect area and the donor site. In this chapter, etiology, clinical features, medical and surgical managements of OAFs, and advantages and disadvantages of different closure methods of closure techniques are discussed in this chapter.

The mandibular bone is an important component of the facial bone, which has a unique role in digestive system, speech, and facial esthetics. For these important functions of mandibular bone, it is vital that surgeons should not only treat function but also consider the esthetics together. Mandibular fractures are among the most common traumatic injuries of the maxillofacial region. Even though treatment modalities are well established and being practiced for a long time, untreated and postoperative complications still decrease the patient’s quality of life. This chapter aims to describe the cause, clinical presentations, diagnoses, and current treatment methods on the basis of resent literature.
