Even at the anatomical boundaries of the head and neck, otolaryngologists are frequently involved in surgical management of both benign and malignant conditions in collaborative efforts with thoracic surgeons in the cervical esophagus or superior mediastinum, ophthalmologists or oculoplastic surgeons in orbital pathology, and neurosurgeons at the skull base. The limits inherent to a single book chapter preclude covering such a broad field comprehensively. Therefore, this chapter will present an overview of selected disease processes in otolaryngology that are of importance to the general surgeon in training. Each section will focus on a specific anatomic subsite of the head and neck because each has a particular anatomy, physiology, and disease processes that make workup and management unique to that head and neck subsite. These sections will address the differential diagnosis of the most common presenting complaints seen in practice. Treatment will focus on both common disorders and urgencies and emergencies that must be recognized early and managed appropriately. Through a targeted history and physical examination, an understanding of the basic anatomy and possible differential diagnoses, and appropriate laboratory or imaging investigations, these common presenting complaints or emergent situations may be logically and efficient distilled to the underlying cause and treated appropriately. Although malignant etiologies may occur in each head and neck subsite and must often be included in the differential diagnosis, for a consistent and comprehensive discussion, the staging and management of malignant head and neck tumors are addressed separately in the final section of this chapter.
