ABSTRACT
The aim of this study was to investigate the measures of displacement, time and velocity of hyoid bone movement in female thyroidectomy patients. Fifty-eight ultrasound videos of 29 women during swallowing were analyzed. The sample was divided into experimental group (EG), composed of 12 women following total or partial thyroidectomy; and control group (CG) of 17 healthy women. The kinematic measures of displacement, time and velocity of hyoid bone displacement were tracked during swallowing of 10 ml of liquid (water) and 10 ml of thickened liquid (honey) in both groups for comparisons. Additional analysis included bolus consistency effect and relationship with clinical characteristics. Ultrasound videos were analyzed according to a standardized protocol using ImageJ software. Displacement, time and velocity of hyoid movement during swallowing of 10 ml of liquid or thickened liquid were not statistically different between female thyroidectomy patients and healthy women. There is no bolus consistency effect on kinematic measures in both groups, but among thyroidectomy patients, velocity of hyoid bone movement is significantly faster in those with swallowing complaints.
ABSTRACT
OBJECTIVE: This review set out to examine the applicability of transcutaneous laryngeal ultrasonography (TLUSG) for the assessment of laryngeal function after thyroidectomy. METHODS: An integrative review of the literature was performed using Medline/PubMed, LILACS, and SciELO databases. The methodological quality of the studies was analyzed using the appraisal tool for cross-sectional studies. RESULTS: All 8 included articles investigated laryngeal function with regard to the risk of vocal fold immobility after thyroidectomy. The results regarding the diagnostic power of TLUSG for this assessment are controversial, and there is a tendency to use this examination as a screening procedure for subsequent confirmation by flexible laryngoscopy. CONCLUSIONS: Transcutaneous laryngeal ultrasonography is a viable, noninvasive, and useful tool to assess laryngeal function after thyroidectomy, but current available evidence suggests that it does not replace flexible laryngoscopy for the diagnosis of vocal fold immobility.

The aim of this study was to investigate temporal ultrasound measurements of the hyoid bone displacement during swallowing following thyroidectomy in women and to relate these measures to age, clinical outcomes, and upper digestive airway symptoms. The sample was divided into an experimental group (EG) of 20 women who underwent thyroidectomy (mean age = 49.55 years ± 15.14) and a control group (CG) of 20 healthy women volunteers (mean age = 40.75 years ± 15.92). Both groups were submitted to ultrasound assessment to obtain four temporal measurements of hyoid bone displacement during swallowing: elevation, anteriorization, maximum displacement, and maintenance of maximum displacement. In both groups, swallowing of ten milliliters of liquid and the same volume of thickened liquid (honey) were analyzed. The images were recorded on video (30 frames/second) and analyzed according to a standardized protocol. Temporal measurements of hyoid bone elevation and maximum displacement during swallowing of thickened liquid were significantly shorter in EG (p = 0.034 and p = 0.020, respectively). There were no differences in the swallowing of liquid, and no other variable was related to the ultrasound temporal measurements investigated. This study concludes that women who undergo thyroidectomy have a shorter time of hyoid bone elevation and maximum displacement during swallowing of 10 mL of thickened liquid.

O histiocitoma fibroso maligno é um neoplasma de origem mesenquimal, do grupo dos sarcomas dos tecidos moles, cuja etiologia é controversa. Relativamente raro na região de cabeça e pescoço, em particular, na cavidade oral, sendo mais freqüente nos membros inferiores. Classifica-se, histologicamente, em cinco tipos, dos quais o pleomórfico é o mais comum. Apresenta-se, clinicamente, como uma massa indolor, de crescimento rápido, produzindo metásteses à distância e, eventualmente, para os linfonodos regionais. Este caso clínico refere-se a uma paciente do gênero feminino, 34 anos de idade, leucoderma, atendida no Serviço de Cabeça e Pescoço do Hospital Napoleão Laureano, na cidade de João Pessoa - Paraíba - Brasil. Ao exame físico locorregional, observou-se uma massa tumoral ulcerada, infiltrativa, medindo cerca de 10,0 x 9,0 cm, localizada na mucosa jugal e no rebordo alveolar inferior do lado direito, comprometendo extensa área da cavidade oral. É diagnosticada como histiocitoma fibroso malígno. Após o diagnóstico, a paciente foi submetida à ressecção cirúrgica da lesão e tratamento quimioterápico complementar
