ABSTRACT
AIMS: Mucormycosis is a rare and aggressive fungal infection with a high mortality rate because of its rapidly progressive and destructive nature. The oral cavity is often affected under opportunistic conditions. We report a 34-year-old woman diagnosed with acute myeloid leukemia complained of slight swelling on the right side of her face with toothache and gingival swelling. An incisional biopsy was performed, and the specimen analysis revealed broad aseptate hyphae with a ribbon-like appearance, which is characteristic of opportunistic Mucorales infection. METHODS AND RESULTS: The oral lesion worsened, and invasion of the fungal infection into the maxillary sinus, nasal cavity, ethmoidal air cells, and sphenoid and frontal sinuses was observed. Partial maxillectomy was performed concomitantly with the ongoing chemotherapy for leukemia. A maxillofacial prosthesis was used for functional rehabilitation. CONCLUSION: Successful management requires a multimodal approach. In this case, the patient required different systemic approaches for treating leukemia and the fungal infection as well as rehabilitation with an obturator prosthesis.

RESUMO As próteses bucomaxilofaciais (PBMF) têm como objetivo a reabilitação oral de pacientes com mutilações decorrentes de cirurgias de câncer de boca. Como parte dessa reabilitação oral, a terapia fonoaudiológica associada ao biofeedback ultrassonográfico da língua possibilita melhor precisão da produção de fala. O presente estudo teve por objetivo caracterizar a produção de fala de um indivíduo com histórico de múltiplas cirurgias oncológicas que levaram à glossectomia total, com auxílio de um dispositivo individualizado de acrílico, idealizado a partir da parceria Odonto-Fonoaudiologia da instituição e confeccionado por especialista em PBMF e terapia fonoaudiológica, utilizando o biofeedback visual com ultrassonografia. O indivíduo era homem, 45 anos, professor aposentado com histórico de carcinoma epidermóide de língua com episódios de recidiva. Como tratamento oncológico, foram realizadas diversas cirurgias associadas à radioterapia, ao longo de sete anos. O tratamento oncológico culminou com a glossectomia total e instalação de osteorradionecrose de mandíbula. O tratamento desta sequela da radioterapia também exigiu múltiplas abordagens cirúrgicas, com perda de grande parte da mandíbula, levando ao severo comprometimento das funções de deglutição e fala. Durante o atendimento multiprofissional da equipe Odonto-Fonoaudiologia de um hospital universitário, foi idealizada a confecção de um dispositivo individualizado de acrílico, objetivando melhorar a inteligibilidade da fala do paciente. Tal dispositivo foi confeccionado por dentista especialista em PBMF e ajustado em conjunto com a equipe de Fonoaudiologia. Com o dispositivo de acrílico adaptado, o indivíduo iniciou a terapia fonoaudiológica associada ao biofeedback, por meio da ultrassonografia de língua, com o objetivo de promover o refinamento da produção de fala dos fones fricativos [s] e [∫]. Ao comparar a avaliação pré-terapia e pós-terapia, foi possível identificar, após a análise das falas por juízes, melhora quanto à Porcentagem de Consoantes Corretas, de moderadamente severa para levemente moderada, bem como a inteligibilidade de fala, de insuficiente para regular. O dispositivo individualizado com a terapia fonoaudiológica associada ao biofeedback produziram resultados de fala satisfatórios, considerando-se a gravidade do caso e o elevado grau de mutilação do paciente.
ABSTRACT The oral maxillofacial prostheses (PBMF) aim the oral rehabilitation of patients with mutilations resulting from oral cancer surgery. The oral rehabilitation was composed of speech therapy associated with ultrasound biofeedback of the tongue, which allows better precision in speech production. The present study aims to characterize the speech production of an individual with a history of multiple oncological surgeries with total glossectomy with the aid of an individualized acrylic device, designed based on the partnership between Dentistry and Speech Therapy and made by a prosthetic dentist, undergoing therapy and speech therapy with visual biofeedback by ultrasound. The individual is a 45-year-old man, retired teacher with a history of tongue squamous cell carcinoma with episodes of recurrence. The cancer treatment was performed by several surgeries associated with radiotherapy over seven years. This treatment resulted in total glossectomy and the presence of osteoradionecrosis (ORN) of the mandible. The sequel to radiotherapy also required multiple surgical approaches with loss of a large part of the jaw, causing severe impairment of swallowing and speech functions. During the multidisciplinary care provided by the Dentistry and Speech Therapy team at a university hospital. The creation of an individualized acrylic device was conceived, aiming to improve the speech intelligibility of the patient. This device was made by a prosthetic dentist and adjusted together with the Speech Therapy team. With the adapted acrylic device, the individual started speech therapy associated with biofeedback by means of tongue ultrasound with the aim of promoting the refinement of the speech production of the fricative headphones [s] and [∫]. When comparing the pre-therapy and post-therapy assessment (after the analysis of the speeches by judges) it was possible to identify an improvement in the Percentage of Consonants Correct (PCC) from moderately-severe to slightly-moderate, as well as speech intelligibility from insufficient to regulate. The individualized device with speech therapy associated with biofeedback produced satisfactory speech results, considering the severity of the case and the high degree of mutilation of the patient.
