ABSTRACT

Angiomyxofibroma of vulva is rare and unique, knownfor local recurrence. It is a mesenchymal tumour. It iscommon in women with reproductive age group. Itsoccurrence in the genital region is a cause for delayedconsultation and social stigma. Clinically examinationshowed it was arising from vulva. Fine NeedleAspiration Cytology (FNAC) showed it to be a benigntumour. Wide local excision was done and confirmationwith Histopathological examination done, whichrevealed Angiomyxofibroma.

ABSTRACT

Objective: To comparatively assess electromyographic (EMG) activity of masseter muscle and maximum bite force among various facial divergence pattern. To compare bilateral variation therefore derive the clinical importance changes in masseter EMG activity. Materials and Methods: The sample size comprised of 90 subjects, age ranging from 16-25 years. They were further classified under three subgroups-normodivergent, hypodivergent and hyperdivergennt based on the cephalometric values. Tekscan Flexiforce B201H sensor along with the associated software was used to record the bite force. The EMG of the superficial masseter muscle was recorded using Biotech Neurocare 2000 surface electromyography machine. The muscle activity was recorded bilaterally from the superficial masseter. The data obtained were statistically analyzed using ROC curve at p<0.05. Results: The bite force of the Hypodivergent group (571.83N±36.65) was more than the Normodivergent (387.26±27.20) and Hyperdivergent groups (373.21N±29.23). The EMG recording of masseter muscle activity in Hypodivergent group was significantly higher than Normodivergent and Hyperdivergent groups. (p-value= <0.01). A significant correlation existed between masseter activity and bite force. Conclusion: The bite force of Hypodivergent jaw base individuals is highest followed by Normodivergent and least in Hyperdivergent individuals.The strong correlation between the muscular activity and the bite force is definitely a contributor to the anchorage value during treatment by fixed Orthodontics.


Objetivo: evaluar comparativamente la actividad electromiográfica (EMG) del músculo masetero y la fuerza de mordida máxima entre varios patrones de divergencia facial. Para comparar la variación bilateral, por lo tanto, derive la importancia clínica de los cambios en la actividad EMG del masetero. Materiales y métodos: El tamaño de la muestra comprende 90 sujetos, con edades comprendidas entre 16 y 25 años. Además, se clasificaron en tres subgrupos: normodivergente, hipodivergente e hiperdivergénico según los valores cefalométricos. Se usó el sensor Tekscan Flexiforce B201H junto con el software asociado para registrar la fuerza de mordida. La EMG del músculo masetero superficial se registró utilizando la máquina de electromiografía de superficie Biotech Neurocare 2000. La actividad muscular se registró bilateralmente a partir del masetero superficial. Los datos obtenidos se analizaron estadísticamente utilizando la curva ROC a p<0,05. Resultados: la fuerza de mordida del grupo hipodivergente (571.83N±36.65) fue mayor que la de los grupos normodivergentes (387.26±27.20) y los hiperdivergentes (373.21N±29.23). El registro EMG de la actividad muscular masetera en el grupo hipodivergente fue significativamente más alto que en los grupos normodivergente e hiperdivergente. (valor de p=<0.01). Existía una correlación significativa entre la actividad del masetero y la fuerza de mordida. Conclusión: la fuerza de mordedura de los individuos hipodivergentes de la mandíbula es más alta seguida por la de Normodivergent y menos en los individuos hiperdivergentes. La fuerte correlación entre la actividad muscular y la fuerza de mordedura definitivamente contribuye al valor de anclaje durante el tratamiento con ortodoncia fija.
