Abstract:
Objective:To investigate the embryologic origin and diagnosis and management of cutaneous cartilage remains of gill origin in the neck. Methods:A total of 15 patients with cervical chondrocutaneous branchial remnants treated in Guangdong Provincial People's Hospital from January 2005 to December 2021 were retrospectively analyzed. They had a common feature showing a tumor in the lower third of the front of sternocleidomastoid muscle. The tumor looked like accessory auricle, never appeared pain or other symptoms of infection, and had no skin orifice. All patients underwent ultrasound examination, which showed an anechoic area under subcutaneous tissue of the neck or face. MRI examination in 6 cases showed subcutaneous irregular nodules the location of the lesion. Surgical resection of cervical chondrocutaneous branchial remnants was performed in all cases. Results:Postoperative pathological examination showed elastic cartilage. No complications were noticed. Recurrence was not observed in the cases by following-up of 8 months to 52 months(median: 41 months). Conclusion:Cervical chondrocutaneous branchial remnants are relatively rare, which may originate from the second branchial arch and may be associated with other congenital malformations. The curative treatment is a complete excision preschool.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
