Benign cartilaginous tumors of the hand, a five-year retrospective study.

Benign and malignant cartilaginous bone tumors of the hand are rare findings, however representing a particular pathology due to the capacity to induce significant functional impairment. Even though a large proportion of tumors of the hand and wrist are benign, these may present destructive characteristics, deforming adjacent structures until compromising function. The most appropriate surgical approach for most benign tumors is intralesional lesion resection. Malignant tumors often require wide excision, up to segment amputation to obtain tumor control. A five-year retrospective study was performed on patients admitted in our Clinic with benign cartilaginous tumors of the hand, in which 15 patients were admitted within this period, 10 presenting with enchondroma, four presenting with osteochondroma, and lastly one with chondromatosis. After clinical and imaging evaluation, all the aforementioned tumors were surgically removed. Definitive diagnosis for all bone tumors, either benign or malignant, was established by tissue biopsy and histopathological examination, dictating therapeutic strategy.

Ramus to Ramus Mandibular Defect Reconstruction with Osteocutaneous Fibula Free Flap - Case Presentation.

Introduction: Head and neck defects after tumor resection can be difficult to reconstruct using autogenous tissue without utilizing a free flap. Osteocutaneous fibula free flap is now considered the gold standard used for mandibular reconstruction after resections due to malignancy. Case presentation: We present the case of a 49-year old female known with an ectopic mucoepidermoid carcinoma involving the mandibula from one ramus to another. After tumor resection, we have reconstructed the mandible by using the only method available for reconstruction in this case - an osteocutaneous fibula free flap. We were able to reconstruct the mandible using 3D printed custom-made surgical guides. Discussion: Postoperative imaging showed that the height and symmetry of the mandible were satisfactory. There were no microvascular failures and the intraoral healing time was about 10 days. The donor site skin defect from the left leg was grafted with an autograft harvested from the ipsilateral thigh. The donor site healed uneventfully. Conclusion: Osteocutaneous fibula free flap is a highly effective method and sometimes the only one available for reconstruction of mandibular defects after resection of intraoral malignancies. Modern technologies, such as surgical planning using computer-aided design, play a critical part in extensive reconstructions, lowering the total intervention time.
