ABSTRACT
ABSTRACT

INTRODUCTION:

Maxillary defects are usually rehabilitated by a prosthetic obturator.

OBJECTIVE:

This study aimed to evaluate the functioning of obturators prosthesis in patients with unilateral defects after maxillectomy.

METHODS:

Of 49 patients, 28 underwent to maxillectomy as a result of tumor ablative surgery, and acquired unilateral maxillary defects. Evaluation of the function was performed by applying the Obturator Functional Scale (OFS).

RESULTS:

From a total of 49 patients, 28 were treated as follows 9 with a conventional retained obturator prosthesis (COP), 11 (39%) with an enhanced retentive obturator prosthesis with stud attachment (POP) and 8 (28%) with an enhanced retentive obturator prosthesis with magnetic attachment (POM). The mean OFS score was 80. Scores on functions of speech, swallowing and chewing reached statistical significances (p < 0.05) among these three subgroups. Comparing COP and MOP groups, the scores of OFS in the domains of "Speech-ability to speak in public" and "Swallowing-leakage with liquids" were significantly higher in AOP group. Comparing COP group, the scores of OFS in "Swallowing-leakage with solid" and "Chewing/eating" domains were increased significantly (p < 0.05) both in MOP and AOP groups.

CONCLUSION:

Obturator prosthesis improves oral function of patients after maxillary defects; the retention of the obturator prosthesis enhanced by the addition of attachments showed more benefits in oral function.
RESUMO
RESUMO

INTRODUÇÃO:

Em geral, os defeitos da maxila são reabilitados por uma prótese obturadora.

OBJETIVO:

O estudo avaliou o funcionamento da prótese obturadora em pacientes com defeitos unilaterais após maxilectomia.

MÉTODO:

De 49 pacientes, 28 foram submetidos a maxilectomia como cirurgia de ablação tumoral e tiveram como sequela defeitos maxilares unilaterais. A avaliação do funcionamento foi efetuada pela aplicação da Escala Funcional do Obturador (EFO).

RESULTADOS:

De um total de 49 pacientes, 28 foram tratados da seguinte forma nove com prótese obturadora retentiva convencional (POC), 11 (39%) com prótese obturadora retentiva com fixação por pino (POP) e oito (28%) com prótese obturadora retentiva com fixação magnética (POM). O escore médio na EFO foi de 80. Os escores para funções da fala, deglutição e mastigação alcançaram significância estatística (p < 0,05) entre os três subgrupos. Na comparação entre os grupos POC e POM, os escores da EFO nos domínios da "Fala-capacidade de discursar em público" e "Deglutição-vazamento de líquidos" foram significativamente mais altos no grupo POP. Na comparação com o grupo POC, os escores da EFO nos domínios de "Deglutição-vazamento com sólido" e "Mastigação/ingestão" estavam significativamente aumentados (p < 0,05) nos grupos POM e POP.

CONCLUSÃO:

A prótese obturadora melhorou o funcionamento oral de pacientes com defeitos maxilares; a retenção da prótese obturadora reforçada pela adição de dispositivos de fixação demonstrou maiores benefícios na função oral.
