How to Measure MIO
Posted by Sarah Schuman, M.S. CCC-SLP on 11/11/2021 to
General Medical and Dental Information
Mouth opening is measured as a MIO or ROM distance. MIO (maximal interincisal
opening) is the distance between the central incisors when the mouth is fully open.
Average MIO for adults is approx. 50mm. By measuring MIO, a therapist can determine
if a patient is WNL or has trismus. ROM (Range-of-Motion) is the maximum distance
the mandible moves. ROM and MIO may be different, e.g. patients with an open bite.Trismus in HNC Patients - 2020 Update

Head & Neck Cancer, Radiation Therapy
When is it best to start trismus therapy? Treatment for head and neck cancer may cause trismus, xerostomia and dysphagia negatively impacting a patient's quality of life (QOL). A new study, Effects of jaw exercise intervention timing on outcomes following oral and oralpharyngeal cancer surgery: Pilot study (, , , et al, 2019), looks at the optimal timing for exercise initiation post-operatively in HNC patients. Initial findings suggest early exercise intervention has a positive effect on some QOL measures!

New Research Correlates Radiation Dose to the Masseter and Pterygoid Muscles with the Development of Trismus (Article Review)
Posted by Sarah Schuman, MS, CCC-SLP on 5/21/2019 to
Head & Neck Cancer, Radiation Therapy
Reconfirmed!! New research reinforces the correlation between radiation dose to the masseter and pterygoid muscles with the development of trismus.
The study “Radiation dose to the masseter and medial pterygoid muscle in relation to trismus after chemoradiotherapy for advanced head and neck cancer” stresses the impact of radiation dose on the ipsilateral masseter muscle and the ipsilateral medial pterygoid muscle in head and neck cancer patients. A meaningful analysis of data was conducted across 83 patients treated for advanced squamous cell carcinoma of the head and neck. These patients participated in a preventive exercise program for mouth opening and MIO measurements were compared. The study concluded that radiation dose on the ipsilateral masseter muscle and ipsilateral medial pterygoid muscle is predictive for trismus.

IMPORTANT HPV VACCINATION UPDATE!!!
Posted by Sarah Schuman, MS, CCC-SLP on 12/17/2018 to
General Medical and Dental Information
On October 5, 2018, the U.S. Food and Drug Administration (FDA) approved the administration of the Gardasil 9 vaccine for women and men between the ages of 28-45 years. Previously the vaccine was indicated for individuals up to the age of 27 years. "Gardasil 9 prevents certain cancers and diseases caused by the nine HPV types covered by the vaccine". Human Papilloma Virus (HPV) can cause head and neck cancer in men and women. It is the cause of most oropharyngeal cancers in United States. These cancers and their treatment may lead to trismus (limited mouth opening) and dysphagia (difficulty swallowing).
The expansion in vaccination ages follows a study in which 3,2000 women between the ages 27-45 years were followed for approximately 3.5 years and it was found that Gardasil was 88% effective in preventing certain HPV related infections and cancers. The results were inferred to apply to men as well.

Trismus in Head & Neck Cancer
Posted by Sarah Schuman, MS, CCC-SLP on 5/25/2018 to
Head & Neck Cancer, Radiation Therapy
Trismus, or restriction to mouth opening, has many implications including difficulty speaking, eating, maintaining oral hygiene, receiving dental procedures and may even affect intubation. Typical measure of mouth opening is 50 mm and highly correlated to body size. An opening of 35mm or less is considered trismus. Trismus is preventable and treatable by engaging in exercise therapy and treatment using jaw motion rehab systems such as the OraStretch® press.
