Background:
Velopharyngeal dysfunction (VPD) in head and neck cancer is frequently clinically reported, affecting both speech and swallowing function. This review sought to identify the tumor subsites and treatment modalities reported in association with VPD and summarize the current reporting methodology of VPD-related speech and swallowing outcomes in patients following head and neck cancer treatment.
Methods:
A literature search was conducted through December 2020 using electronic databases and a total of 15 studies were included in review.
Results:
Reported VPD was largely secondary to palate resections. Large variability in reporting methodology was noted with heavy reliance on speech-related perceptual measures and swallowing-related patient-reported outcomes over imaging and instrumental evaluations.
Conclusions:
This review revealed inconsistencies in evaluating and reporting VPD, which likely translates into inconsistencies in clinical management. Further attention to VPD secondary to other head and neck malignancies would provide a broader perspective on VPD through head and neck cancer treatment.

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,...

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...

Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
