Anatomy and Disorders of the Beak and Oral Cavity of Birds.

Abstract

Cranial kinesis of the avian beak is complex; particularly in birds with prokinetic beak movement, such as psittacine birds. A number of diseases can result in damage to the bony and soft tissue structures of the beak and can lead to secondary pathology, such as beak deviation, abnormal rhamphothecal growth and wear, and opportunistic infections. A solid understanding of species-specific anatomic variations is essential before attempting rhamphothecal restoration or surgical repair. Many diseases of the oral cavity can appear similar on initial clinical evaluation and therefore warrant appropriate diagnostic testing.
