Reverse voice, typically transitional, can be a pathological condition. This study details a case of continuous reverse voice use, exploring clinical, functional, and psycho-dysfunctional aspects.
Area of Science:
- Laryngology
- Speech-Language Pathology
- Voice Disorders
Background:
- Reverse voice is recognized as a transient phenomenon during typical voice production.
- Its role as a distinct pathological entity is less understood.
- This study investigates reverse voice as a persistent condition.
Observation:
- A case study of a patient using continuous reverse voice instead of normal phonation is presented.
- Clinical, functional, and instrumental investigations were performed.
- The patient's psycho-dysfunctional context was also examined.
Findings:
- Instrumental analyses of fundamental frequency and laryngeal function aligned with existing literature.
- The study highlights the unique challenges in managing persistent reverse voice.
- Therapeutic interventions and patient acceptance of typical voice production were discussed.
Implications:
- This research deepens the understanding of reverse voice as a pathological entity.
- It provides insights into the assessment and management of such voice disorders.
- Findings can inform speech therapy strategies for patients with persistent reverse voice.

Larynx
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...

Pharynx
Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...
