Enormous oromandibular defects in children remain a reconstructive challenge due to the region's unique features and the scarcity of a perfectly matched recipient site. The osteocutaneous fibula-free flap (OCFFF) is an excellent option for these defects. Most reports on oromandibular reconstruction in children are limited to surgical techniques instead of long-term follow-up, especially in resource-limited settings. We reported a 9-year-old child who presented with a massive oromandibular defect caused by a high-energy gunshot. Firstly, the patient was treated with debridement, lower defect edges approximation, and tracheostomy. After one week, the procedure of OCFFF was performed, and two months later, the lower lip was reconstructed using a tongue flap. The aesthetic outcome was excellent at two years, and the patient could speak and eat without impaired oral function. In conclusion, microsurgical reconstruction using OCFFF for massive oromandibular defects in our child patient was safe with satisfactory facial aesthetics and oral function.
Introduction
while reconstruction of complex wounds with severe tissue defects has been a significant problem in plastic surgery, free flap microsurgical procedures could solve many of these problems. In Yemen, data regarding free flap microsurgery for complex wounds are scarce. This study aimed to share our microsurgery experiences in repairing complex wounds using different free flaps in a resource-limited setting.
Methods
a retrospective cross-sectional study between April 2019 and June 2022 conducted at 21 University-affiliated hospitals included 30 patients with complex wound defects that were not amenable for regional, pedicle procedures, or skin grafts and underwent microsurgical reconstructions with deferent free flap tissue transfer. The primary outcome was flap survival or failure, while the secondary outcome was postoperative complications.
Results
the main age was 34.76 ± 16.88 years, with 24 (80%) males and 6 (20%) females. Replacing extensive tissue loss caused by road traffic accidents was the most common indication (36.6%). The mean defects required to be reconstructed were 84.9 ± 44.70 cm

. The lower extremities accounted for the majority of reconstructed defects (50%), and mostly (23.3%) involved the leg. Only 10 (33.3%) flaps were performed immediately within 48 hours of trauma. The fibulae osteo-cutaneous free flap (30.0%), radial forearms free flap (23.3%), and anterolateral thigh flap (23.3%) were used most commonly. All flaps were harvested and repaired under loupe magnification or operative microscope by a single surgeon. The overall flap success rate was 83.3%. The total complication rate was 23.3%, and postoperative infection and partial flap necrosis occurred in 3 (10.0%) and 2 (6.6%) patients, respectively. A total flap loss occurred in 5 (16.7%) patients.
Conclusion
reconstruction of complex wounds with microsurgical free flaps is a viable option even in a resource-limited setting. In our study, microsurgery with fibulae osteo-cutaneous free flap was the most commonly used. Despite many limitations, microsurgical free flaps were effective in treating individuals operated on in our setup with a limb salvage rate of 83.3%.
Papillary thyroid cancer (PTC) coexistent with esophageal squamous cell carcinoma (SCC) is of rare occurrence. We report a 45-year-old female who presented with painless anterior neck swelling for the past year. Ultrasonography showed a left hypoechoic thyroid mass measured 20x13 mm without lymph node enlargement. The fine-needle aspiration cytology was suggestive of PTC. Consequently, total thyroidectomy with bilateral neck dissection was performed. Incidentally, a small mass measuring 4x2 cm arising from the esophageal wall was identified and resected. Postoperatively, the patient developed a small esophageal fistula which was treated conservatively. The histopathological examination confirmed the diagnosis of PTC and SCC of esophageal mass. The patient underwent radiotherapy, and radioactive iodine therapy, and had acceptable conditions within two years of follow-up. In conclusion, even though the coexistence of PTC and esophageal SCC is rare, the possibility of concurrence of both tumors should be considered if an incidental mass was identified intraoperatively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
