Abstract: Ameloblastoma is a benign tumor of the mandible, which
is not commonly diagnosed in the early stages. The extensive
mandible resection may be needed for treatment. In this report, we
present 6-year follow-up results of a patient who had undergone
hemimandibulectomy and mandible reconstruction with free vas-
cularized fibular flap, costochondral rib graft to restoration of the
temporomandibular joint, and iliac bone graft to enhance the vertical
height of the mandible. The long-term results are very satisfactory.

A
meloblastoma is a benign tumor that develops from the epi-
thelial cellular elements and dental tissues, localized in the
mandible and the upper jaw.

In many cases, ameloblastoma is not
diagnosed in the early stages because this benign tumor is often
asymptomatic and has a slow grow pattern without evidence of
swelling. Despite the benign nature of the tumor, ameloblastoma is
a locally aggressive tumor and malignant transformation is pos-
sible.

To avoid recurrence and possible malignant transforma-
tion, the tumor should be resected totally with or without border
preservation.

The mandible is a major component of the human facial ap-
pearance and makes a great contribution to the orofacial function.
For this reason, mandibular bone defects may result in oral function
deficits, aesthetic disturbances, and psychologic problems.

Many
mandibular reconstruction options are available.
In this clinical report, we present 6-year outcomes of a pa-
tient who had undergone mandible and temporomandibular joint
(TMJ) reconstruction with combined free vascularized fibular flap,
costochondral rib, and iliac bone graft for reconstruction of the
hemimandibulectomy defect.
CLINICAL REPORT
A 21-year-old man was admitted to our clinic with a chief
complaint of swelling in the lower jaw (Fig. 1). He has noticed a mass
on the right side of his face, and the mass has grown slowly since
childhood without known etiology. On the basis of physical exam-
ination and radiography, the right ramus and the greater part of the
right mandibular body were involved, and we performed incisional
biopsy for a definite diagnosis and treatment (Fig. 2). The pathologic
diagnosis of the biopsy specimen was reported as ameloblastic fi-
broma, and the treatment was planned after careful analysis of each
factor. We performed right hemimandibulectomy and removed the
tumor and the right hemimandible (Fig. 3). For reconstruction,
15-cm-long free fibular flap with a 3 Â 10-cm skin island was
planned and harvested. Osteotomies were performed to shape the
flap as a potential ramus and corpus of the neomandible. To restore
the TMJ, a 6-cm-long costochondral composite graft was harvested
from the sixth rib and the chondral segment was shaped like a
condyle of the mandible. In addition, the bony segment of the graft
was sharpened to a cone to be embedded in the proximal edge of the
flap that was planned as a connection with fibula flap (Figs. 4A, B).
Subsequently, the bony segment of the costochondral graft had been
implanted in a drilled hole at the proximal part of the fibula flap and
a new mandible with a condyle was established (Fig. 5). The flap
was placed to the defect, and rigid fixation was carried out. The
artery and the veins of the flap were anastomosed to the facial artery
and the jugular vein in an end-to-end and end-to-side fashion, re-
spectively. The operation was successful. There were no major or
moderate complications.
After 6 months, the patient was reoperated on to prepare the
neomandible for the dental osteoimplantation, and rigid internal
fixation materials were removed and the iliac bone graft was placed
