Oral rehabilitation following removal of a rhabdomyosarcoma and subsequent microstomia: a case report

Prosthetic rehabilitation for a patient treated for embryonal rhabdomyosarcoma

A female patient, now aged 17 years, was diagnosed with rhabdomyosarcoma (RMS) in the right pterygopalatine fossa when she was 3 years old. The RMS was successfully treated by excision, but the subsequent radiation and polychemotherapy resulted in the complete anesthesia of the distribution area of the right trigeminal nerve and loss of vision in the right eye. The patient also experienced pain in the mandibular joints and masticatory muscles. Panoramic radiographs displayed a multiple agenesia of the permanent teeth and underdeveloped apices. Treatment involved the fabrication of a complete maxillary denture. A removable device was fabricated to evaluate her response to an occlusal vertical dimension increase of 6 mm and provide a stable intercuspal position. After wearing the prosthesis for 6 months, the patient reported that she was completely free of symptoms.

Surgical correction of microstomia in a patient with antilaminin 332 mucous membrane pemphigoid

Microstomia is a term used to describe a small oral aperture. Most of the reported cases are caused by scar contracture after facial trauma, burn injury, and tumor excision. We experienced a rare case of microstomia in a patient with antilaminin 332 mucous membrane pemphigoid, which was an acquired autoimmune disease and showed blisters and erosive lesions mainly on the mucous membranes. The patient had recurrent aphthous stomatitis and presented microstomia caused by scar contracture of oral mucosa. We surgically corrected microstomia by 5-flap Z-plasty for commissuroplasty and 2 Z-plasty of both upper and lower lips for an enlargement of oral aperture. The patient could achieve an enough oral aperture and was satisfied with the result. There was no recurrence of microstomia for 2 years.
