Objectives: The objective of this study is to explore the clinical diagnosis and treatment of the congenital sternoclavicular sinus in the region of sternoclavicular joint, providing valuable insights for clinical practice in children.
Methodology: A retrospective review of case notes was conducted for all patients treated for congenital sternoclavicular sinus at a tertiary care pediatric otolaryngology practice from January 2022 to September 2023.This review analyzed the clinical presentations, imaging examination, pathological examination, and treatment.
Results: A total of 56 patients with congenital sternoclavicular sinus were included in the study, with a mean age of 4.10 ± 2.57 years old. Among these patients, the sinuses were located on the left side in 43 cases,on the right side in 12 cases,and bilaterally in one case.While two patients never experienced inflammation, 54 patients did, and 45 of them underwent incision and drainage before excision. Imaging examination, including ultrasonography and computerized tomography (CT) scans, revealed characteristics such as thickening of subcutaneous tissue,subcutaneous tubular structures or tubercles in front of the clavicle,and irregularly shaped lesions with clear borders and uneven internal low echo, Pathological examination confirmed that the sinuses were lined by squamous epithelium in all patients.
Conclusions: The congenital sternoclavicular sinus may be a remnant of the fourth branchial cleft on the skin side.Complete resection of the sinus during the quiescent phase of inflammation is the recommended curative treatment to prevent recurrent infection.
