Deglutition, nutritional status and salivary flow in patients after treatment for head and neck cancer The treatment of head and neck cancer leads to consequences in the stomatognatic system, nourishment and nutritional condition. However, little is known concerning these factors in relation to the evolution of patients after the antineoplastic treatment is finished. The current study aimed to verify the connection among deglutition function, nutritional status and salivary flow in patients after treatment for head and neck cancer. The study has included 17 patients (14 men and 03 women), 53 years old average. The deglutition was evaluated through videofluoroscopy tests and surface electromyography on masseter muscles, orbicularis of the mouth and supra hyoids. The nutritional status was assessed through anthropometry (ICM, CMB and %GC) and diet evaluation by using a 24-hour food inventory, and the salivary flow was evaluated through mechanical stimuli. The analyses indicated that 66.7% of patients presented deglutition with functional limitations, with a waste scale of 58.3%, 66.7% and 58.3% with average of barium line in the structure to pudding, honey and liquid consistency, respectively, while laryngeal penetration reached 8.3% during liquid deglutition. For the surface electromyography, during flan deglutition, the time of muscle activity was above normal values. The values obtained from the electrical activity ampleness were similar to the studied muscles, which is not prospective in patients who do not have functional changes in deglutition. The anthropometric evaluation showed 41.2% of patients had eutrophy, according to ICM. The evaluation of muscle and adipose tissue showed eutrophy in 52.9% and 41.2%, respectively. The diet evaluation indicated that 64.7% had their energy consumption above the levels considered ideal, however, carbohydrates, proteins and lipids ingestion were normal, considering that 53.4% of patients ingested fewer micronutrients than necessary. The salivary flow test using mechanical stimulus showed that 82.3% had saliva production far below adequate. There was a significant correlation between muscle tissue reserve and time of muscle activity during deglutition, as well as Sodium and Calcium consumption with amplitude of muscular electrical activity for masseter muscles and orbicularis of the mouth, for liquid and honey consistency, respectively. No correlation between data of deglutition evaluations and salivary flow was found. Therefore, the relation between deglutition and nutritional status was established in the study, pointing that the adequate ingestion of proteins, sodium and calcium micronutrients affects muscle activities during deglutition in patients who survived head and neck cancer. Key words: Head and neck cancer. Deglutition. Nutritional Status. Xerostomia. (em RMS), porcentagem da atividade elétrica e tempo de recrutamento muscular durante a deglutição para a consistência pudim
Determine the relationship between swallowing function, nutritional status, and salivary flow in patients after head and neck cancer treatment. This pilot study included 17 patients. Swallowing was assessed through videofluoroscopy and surface electromyography (sEMG), nutritional status through anthropometry and dietary assessment, and salivary flow both with and without mechanical stimulation. Test analysis showed that 66.7% of patients had functional limitations in swallowing in 58.3%, 66.7%, and 58.3% residue scale with an average of a line of barium on a structure for pudding, honey, and liquid consistencies, respectively. Laryngeal penetration was found in 8.3% during the swallowing of liquid. Surface electromyography (sEMG) showed above normal values for muscle activity time during the swallowing of pudding. Anthropometric assessment and muscle and adipose tissue indicated eutrophy. Salivary flow test with mechanical stimulus showed that 82.3% of patients' salivary production was well below the appropriate level. There was a significant correlation between muscle tissue reserve and muscle activity time during swallowing in the studied muscles (left masseter p = 0.003, right masseter p = 0.001, suprahyoid p = 0.001, orbicularis oris = 0.020), all in pudding consistency. This pilot study confirmed the relationship between swallowing and nutritional status for its participants, showing that appropriate protein intake influences muscle activity during swallowing in head and neck cancer survivors.
Head and neck cancer damages the oral health and chewing performance, impairing the nutritional status and quality of life even after treatment completion. Objective: This study investigated the effect of treatment on the chewing function, the influence on oral health in chewing function and the relationships between chewing, nutritional status and quality of life in individuals after treatment of head and neck cancer. Methods: The study was conducted on twenty individuals who were evaluated by surface electromyography; nutritional status; evaluation of oral health and quality of life. Results: The results of electromyography showed an asymmetric pattern, with predominance of activity on the working side. The correlations evidenced that the greater the use of upper dentures and caries activity, the greater the asymmetry of muscle activity, while the greater need of lower denture led to more chewing cycles. The lower the body fat percentage, the greater the symmetry of muscle activity; and the lower the recruitment of temporalis muscles, the greater the physical limitation. Conclusions: It was concluded that, in individuals after treatment of head and neck cancer, there was relationship between the correlated variables.
