“…Therefore, a portion of the muscle must be included in the flap. 8,11,20,21 A few authors have previously reported using the supraclavicular osteocutaneous flap based on the TCA pedicle. Pallua and Wolter 16 were among the first to describe the supraclavicular fasciocutaneous flap and later demonstrated the use of the osseous part of the clavicle based on the TCA pedicle to reconstruct an anterior tracheal defect.…”

“…Several flap configurations have been developed based on the muscle attached to the clavicle, which provides the periosteal blood supply-for example, the clavicular head of pectoralis major, the clavicular head of the sternocleidomastoid, and the trapezius containing lateral part of the clavicle. [6][7][8][9][10][11][12][13] These flaps are often referred to as compound myoosseous flaps, and most receive blood supply from either the thoracoacromial or the suprascapular artery. 9 In 1970, the early pioneers of the vascularized clavicular bone flap successfully restored the mandibular continuity by tubing the supraclavicular skin around the clavicle; then, the flap was delayed for 4 weeks before raising and insetting into the defect.…”

“…Researchers have described the use of the clavicle as a free vascularized bone in the reconstructive field. Several flap configurations have been developed based on the muscle attached to the clavicle, which provides the periosteal blood supply—for example, the clavicular head of pectoralis major, the clavicular head of the sternocleidomastoid, and the trapezius containing lateral part of the clavicle 6–13 .

Objective To describe the anatomy of the transverse cervical artery and to prove its perfusion to the clavicle using indocyanine green fluorescence angiography as an alternative vascularized bone for head and neck reconstruction. Study Design Cadaveric dissection. Setting Anatomy lab. Methods Twenty-two necks and shoulders from 11 fresh-frozen cadavers were dissected. The transverse cervical artery diameter, length, emerging point, and the length of clavicle segment harvested were described. Photographic and near-infrared video recordings of the bone’s medial and longitudinal cut surfaces were taken prior to, during, and after indocyanine green injection. Results The transverse cervical artery originated from the thyrocervical trunk and emerged at the level of the medial one-third of the clavicle in 22 of 22 (100%) specimens. The average length of the pedicle was 3.6 cm (range, 2.2-4.4 cm), and the mean diameter was 2.5 mm (range, 1.8-3.4 mm). The harvested bone had a mean length of 5.1 cm (range, 4.3-5.8 cm). After injecting the indocyanine green, 22 of 22 (100%) specimens showed enhancement in the periosteum, bony cortex, and medulla. Conclusion The middle third of the clavicle can be reliably harvested as a vascularized bone with its perfusion solely from the transverse cervical artery pedicle, as shown by the near-infrared fluorescence imaging. The pedicle was sizable and constant in origin.

“…Ameloblastoma pada mandibula paling banyak terjadi di ramus dan regio posterior mandibula dengan persentase 11% dari semua tumor odontogenik mandibula. 1,2,3,4,5,6,7 Menurut klasifikasi baru WHO tahun 2017 tentang klasifikasi ameloblastoma menjadi jenis ameloblastoma, unikistik, dan ekstraoseus/ perifer. 8,9 Sebagian besar jenis ameloblastoma memiliki batas difus invasif dan tingkat kekambuhan yang tinggi kecuali jenis perifer dan unikistik.…”

“…16,17,18,19 Alternatif untuk rekonstruksi defek mandibula adalah penggunaan cangkok tulang non-vaskularisasi, yang melibatkan pengambilan cangkok tulang hanya dari tempat-tempat seperti iliaka tulang rusuk, fibula, kalvarium, atau bagian mandibula itu sendiri. 1,2,3,4 Teknik ini memiliki keuntungan untuk mempersingkat durasi operasi, lebih sedikit kehilangan darah dan lebih terjangkau bagi pasien. Hal ini menjadi pertimbangan penting, terutama di wilayah yang kekurangan tenaga ahli atau kekurangan infrastruktur dan sumber daya ekonomi untuk melakukan anastomosis mikrovaskuler yang diperlukan untuk cangkok tulang vaskularisasi.…”

Pendahuluan: Ameloblastoma adalah tumor invasif lokal dengan insidensi kekambuhan yang tinggi jika tidak dieksisi sepenuhnya. Mandibulektomi segmental sebagai pilihan tatalaksana yang dapat menyebabkan deformitas dan asimetri pada wajah, serta masalah pengunyahan. Pemulihan defek setelah reseksi mandibula menimbulkan masalah yang cukup berat. Tujuan laporan kasus ini untuk melaporkan hasil rekontruksi menggunakan cangkok tulang non-vaskularisasi mandibulektomi segmental pada pasien dengan ameloblastoma mandibula. Laporan kasus: Pria berusia 33 tahun datang ke Poliklinik Rawat Jalan Bagian Bedah Mulut dan Maksilofasial RS Persahabatan dengan keluhan utama pembengkakan mandibula yang perlahan bertambah dan tidak nyeri sejak enam tahun lalu. Pemeriksaan ekstra oral tampak asimetri wajah, bukaan mulut tidak ada limitasi, tidak teraba pembesaran kelenjar getah bening regio leher. Pemeriksaan intraoral didapatkan adanya benjolan regio mandibula kiri dengan batas tegas, konsistensi padat, permukaan tampak trauma oklusi gigi antagonis, immobile, dan terdapat nyeri tekan. Gambaran radiologis menunjukan lesi radiolusen multilokuler menyerupai honeycomb pada corpus mandibula kiri meluas ke regio ramus mandibula kiri. Pemeriksaan biopsi menunjukkan hasil ameloblastoma tipe folikuler pada mandibula kiri dan dilakukan mandibulektomi segmental dengan rekonstruksi cangkok tulang fibula non-vaskularisasi. Sembilan bulan setelah operasi, cangkok tulang non-vaskularisasi tidak menunjukkan komplikasi intraoral dengan bekas luka submandibular ekstraoral baik. Simpulan: Cangkok tulang fibula non-vaskular dapat dipertimbangkan sebagai salah satu pilihan untuk rekonstruksi setelah mandibulektomi segmental pada pasien ameloblastoma.Kata kunci: Mandibulektomi segmental, cangkok fibula non-vaskularisasi, ameloblastoma folikuler. ABSTRACTIntroduction: Ameloblastoma is a locally invasive tumour with a high incidence of recurrence if not completely excised. Segmental mandibulectomy as a treatment option that can cause facial deformities and asymmetry and mastication problem. Recovery of the defect after mandibular resection presents a severe problem. This case report was aimed to report the results of reconstruction using a segmental non-vascularised mandibulectomy bone graft in a patient with mandibular ameloblastoma. Case report: A 33-year-old male came to the Outpatient Polyclinic of the Oral and Maxillofacial Surgery Division of Persahabatan General Hospital with the chief complaint of mandibular inflammation, which was slowly increasing yet painless since six years prior. Extraoral examination showed facial asymmetry, no limitation in mouth opening, no palpable enlargement of lymph nodes in the neck region. Intraoral examination revealed a lump in the left mandibular region with firm borders, solid consistency. The surface appears to be traumatic occlusion of the antagonist tooth, immobile, and tenderness was found. Radiological features showed a multilocular, honeycomb-like radiolucent lesion on the left mandibular body extending into the left mandibular ramus region. A biopsy showed follicular ameloblastoma in the left mandible, and a segmental mandibulectomy was performed with non-vascular fibular bone graft reconstruction. Nine months after surgery, non-vascular bone grafts showed no intraoral complications with either extraoral submandibular scar. Conclusion: Non-vascular fibular bone graft can be considered an option for reconstruction after segmental mandibulectomy in ameloblastoma patients. Keywords: Segmental mandibulectomy, non-vascularised fibula graft, follicular ameloblastoma.

The research program of the Center for Economic Studies (CES) produces a wide range of theoretical and empirical economic analyses that serve to improve the statistical programs of the U.S. Bureau of the Census. Many of these analyses take the form of CES research papers. The papers are intended to make the results of CES research available to economists and other interested parties in order to encourage discussion and obtain suggestions for revision before publication.
