Anatomy and Physiology of Phonation
Phonation is primarily the result of aerodynamic forces acting on the inherently elastic tissue of the vocal folds, setting them into vibration and creating acoustic energy which we call “voice.”…

Voice Rehabilitation after Laryngeal Cancer
Cancer is a disease resulting from irregular development and spread of abnormal cells in one or more parts of the body. 1 Laryngeal cancer (▶ Fig. 9.1) is a subtype…
Laryngeal Endoscopy and Stroboscopy
Endoscopy (endo—“within”; oscopy—“to look at”), in the context of medicine, is a procedure that allows a healthcare professional to look inside the body with the use of an endoscope. As…
The Voice Diagnostic: Initial Considerations, Case History, and Perceptual Evaluation
Organization of the Clinical Voice Evaluation In the following four chapters, we will describe the basic process for assessment and diagnosis of voice as carried out by the speech–language pathologist/voice…
Voice Treatment: Orientations, Framework, and Interventions
Habilitation is the processes of helping an individual with an impairment or limitation realize their maximum potential—its purpose is to enable and enhance. Rehabilitation is the process of helping an…
Medical Treatment of Voice Disorders
Speech–language pathologists (SLPs) who evaluate and treat populations with voice disorders work collaboratively with other medical professionals as part of a voice care team. In most situations, the primary members…
Aerodynamic Analyses of Vocal Function
In ▒Chapter 1░, we defined phonation as the aerodynamic and muscular influences acting on the tissue of the vocal folds, setting them into vibration and creating acoustic energy that we…
Orbital Trauma Management, Reconstruction, and External Approaches to the Orbit
Diagnostic Workup for the Orbital Blowout Fracture Patient In cases in which there is an isolated orbital blowout fracture (i.e., the orbital rims are intact), the leading theory for the…
Management of Iatrogenic Orbital Injury
Prevention 18.2.1 Preoperative Considerations A thorough history should be taken to identify factors that increase the likelihood of orbital injury, such as preoperative abnormality of the lamina papyracea. These factors include…
Radiologic Assessment of the Orbit and Lacrimal System
Imaging Techniques 3.2.1 Computed Tomography Modern CT scanners produce high-resolution images that can be reformatted into multiple planes. Intravenously administered nonionic iodinated contrast is primarily used in the setting of infection,…
