[The experience of interdisciplinary interaction in elimination of midface deformation (clinical observation)]. / Opyt mezhdistsiplinarnogo vzaimodeistviya pri ustranenii deformatsii srednei zony litsa (klinicheskoe nablyudenie).

Fibrous dysplasia is a hamartoma appearing as a benign pathologic process in which normal bone tissue formation is replaced by overgrowth of fibrous connective tissue. The problem of diagnosis and treatment of patients with fibrous dysplasia remains unsolved in the absence of a uniform understanding of its etiology and pathogenesis. Treatment and rehabilitation of patients with midface fibrous dysplasia is a complicated medico-social problem, which requires interaction of specialists of different fields to resolve it. The disease presents a practical interest for doctors of more than 20 specialties, as it can lead to disability. The present article describes a clinical case of interdisciplinary interaction of specialists in the fields of maxillofacial surgery, ophthalmology, otorhinolaryngology, plastic surgery and radiology involved in complex treatment of a patient with midface fibrous dysplasia accompanied by eyeball dislocation, decreased vision, as well as progressive impairment of nasal breathing function. The performed treatment resulted in favorable functional and aesthetic outcomes including elimination of exophthalmos, vertical strabismus, lacrimation disorders, nasal breathing disorders, increase of visual acuity and improvement of external appearance.

The purpose of the study was to increase the effectiveness of surgical treatment and rehabilitation of patients with severe mandibular atrophy by means of autogenous free vascularized fibula transplant use with subsequent dental implants placement in the reconstructed mandible and implant-retained fixed dentures. In 2017 5 female patients underwent surgical treatment of severe mandibular atrophy with autogenous free vascularized fibula transplant in Maxillofacial Surgery department of CRID with additional nonvascularized iliac bone grafts and functional rehabilitation with implant-supported constructions in two of the cases. Due to its form, length and vascularization fibular bone represents a good plastic material for full length mandibular alveolar part reconstruction. The inclusion of the skin paddle in the autogenous free vascularized fibula transplant promotes secure primary closure of the surgical wound in the oral cavity. The use autogenous free vascularized fibula transplant in patients with severe mandibular atrophy with demands a thorough presurgical planning and intraoperative modeling.

One of the most important steps in achieving aesthetical and functional result in mandible reconstruction with fibula free flap is positioning of the bony part relative to the basis of the native mandible. Positioning fibular bony part continuing inferior mandible border may produce a high discrepancy between the residual mandible and fibula bone that results in difficulty in denture rehabilitation. Positioning fibular bony part continuing alveolar mandible border creates asymmetric jowls and changed shape of jawline in border-line zone. The double-barrel technique solves this problem, but needs a meticulous preoperative planning and precision free fibula flap modelling.
