Oculofacial Prosthetic Rehabilitation Complemented With Temporary Fillers and Neurotoxin

Abstract

: Surgical treatment of head and neck cancer causes severe tissue loss, therefore, deformities and psychosocial consequences. In cases involving orbit exenteration, satisfactory reconstruction can only be achieved with prosthetic replacement, despite successful reconstructive plastic surgery. Extraoral implants, 3D scanning, and prototyping technologies have contributed to increase satisfactory aesthetic results of oculofacial prosthesis. However, to achieve prosthetic rehabilitation refinement, patients' biological tissues have been treated with injectable cosmetic adjuncts methods as complements to results. This study aimed to describe the use of botulinum toxin type A, hyaluronic acid, and calcium hydroxyapatite previously to oculofacial prostheses manufacturing, in 5 oncologic patients of a rehabilitation unit. Outcomes produced by additional cosmetic methods on tissues, prostheses planning, and overall facial rehabilitation were observed and registered by photographs. Botulinum toxin type A, hyaluronic acid, and calcium hydroxyapatite has shown to be useful in improving asymmetries, volumizing surgical depressions and dissembling atrophic scars. Presenting an additional resource to improve overall results, enabling the manufacturing of smaller, thinner, and better-fitting oculofacial prostheses. Limitations as chronic infection and necrosis episodes, related to filler injection into previously irradiated sites, were described. The temporary effect of the materials used generates a need for reapplications but increases the safety of such procedures and enables patients' cancer treatment follow-up.

Tratamiento con toxina botulínica en pacientes oncológicos

“…La miastenia gravis es el síndrome paraneoplásico más común diagnosticado en estos pacientes. Se sabe que la TBA está contraindicada en pacientes que padecen enfermedades neuromusculares como la mencionada miastenia gravis, la esclerosis lateral amiotrófica y el síndrome de Eaton Lambert [6,8,[19][20][21][22].…”
