Early soft-tissue coverage is critical for treating traumatic open lower-extremity wounds. As free-flap reconstruction evolves, injuries once thought to be nonreconstructable are being salvaged. Free-tissue transfer is imperative when there is extensive dead space or exposure of vital structures such as bone, tendon, nerves, or blood vessels. We describe 2 cases of lower-extremity crush injuries salvaged with the quad flap. This novel flap consists of parascapular, scapular, serratus, and latissimus dorsi free flaps in combination on one pedicle...

Ameloblastic carcinomas are rare malignant lesions with 3 mandibular pediatric cases reported in the literature. We present a case of ameloblastic carcinoma in situ in a 15-year-old male with a right mandibular cystic lesion on computed tomography. The incisional biopsy revealed plexiform ameloblastoma. Due to the infiltrating and aggressive nature of the tumor, the patient underwent hemimandibulectomy and immediate reconstruction with a vascularized osteocutaneous fibula free flap. The final pathology was read as ameloblastic carcinoma in situ...

Whilst the newly established biomechanical conditions following mandibular reconstruction using fibula free flap can be a critical determinant for achieving favorable bone union, little has been known about their association in a time-dependent fashion. This study evaluated the bone healing/remodeling activity in reconstructed mandible and its influence on jaw biomechanics using CT data, and further quantified their correlation with mechanobiological responses through an in-silico approach. A 66-year-old male patient received mandibular reconstruction was studied...

Prosthetic replacements in the 19th and early 20th century were superseded by pedicled flaps and obturators. These have subsequently been superseded by free tissue transfer which currently is the mainstay of reconstructive jaw surgery. Although malignant and benign processes of the jaws are the predominant cause of segmental defects, a significant proportion still occurs due to trauma, or even iatrogenic causes such as radiotherapy. The varied aetiologies demand a nuanced approach to reconstruction and although the techniques remain similar the timing can be quite different...

Mandibular reconstruction after partial or subtotal resection is considered a challenging procedure that is crucial for facial contour and function. Many reports regarding the reconstruction of mandibular defects have been published over the years. The fibula free flap has become a popular option for mandibular reconstruction since its introduction by Hidalgo in 1989. However, the locations of the reconstructed mandibular angle and the condyle of the fibular bone segments play a crucial role in facial symmetry and function...

For young growing children before the end of skeletal maturity, the growth activity of the grafted bone after hemimandibulectomy is not well-known. After an adolescence, such a patient may have facial deformity because the anterior growth point of the mandible is in the condylar neck. A 13-year-old boy was performed hemimandibulectomy with immediate mandibular reconstruction by fibula free flap (FFF) because of a huge ameloblastic fibroma. The authors evaluated the length of FFF on the images of computed tomography (CT) at 5 and 60 months after the operation and compared them by calculating growth rates...
