These images were likely suggestive for adamantinoma. That hypothesis led to a particular
operative interventation with the aim of a definitive diagnosis and treatment. In fact the
histologic exam would have led, or not, to a mandibular resection. So left mucous fornix
section was performed in order to uncover the mandibular bone from 3.6 to 3.8 dental
elements and to dissect the bone through osteotribe, as long as the lesion was found.
Strangely enough the surgical finding was a rarefaction of the bone, no capsular structure or
any other elements that could help with the diagnosis were observed as well. Consequently
a conservative surgical technique was carried on, such as cutting out the bone box with 3.7
and 3.8 because of their roots inclusion in the osteolitic lesion as well. The missing bony part
was filled with a demineralized bone matrix, in order to prevent iatrogenic fracture. So
before performing a mandibular ramous resection, we have been waiting for the definitive
histologic diagnosis. Unfortunately, against every expectation, it resulted as a follicular cyst
within Candida A. yeasts. It was performed a batteriologic exam that resulted positive for C.
Albicans too and for Hafnia alveii. Antibiotic and antimicotic therapies were carried out for
a long period. After three months patient underwent to a Orthopanoramic x-rays, that
revealed the biomaterial integration but a surgical interventation of removing bio-bone it
was necessary in order to assure the complete eradication of the Candida infection
.

R.A, a male of 40 years old,
affected by the Goldenhar syndrome, he underwent to differentreconstructive surgical
treatments, to restore the normal symmetry of the face soft tissues. The patient showed a
facial asymmetry characterized by an atrophy of the right hemifacial soft tissues, associated
to auricular agenesys, and a behind-positioning of the left auricle.(FIGURE 9)
