Chronic maxillary atelectasis (CMA) is a progressive alteration in the volume of the maxillary sinuses that may result in facial asymmetry. CMA in asymptomatic patients is known as silent sinus syndrome (SSS) and is a rare entity, especially in pediatric patients. This study reports a case of SSS in a pediatric patient who received an early diagnosis through cone-beam computed tomography (CBCT). An asymptomatic 12-year-old female patient in orthodontic treatment presented with opacification of the left maxillary sinus on a panoramic radiograph. Clinically, the patient had discrete hypoglobus and enophthalmos. CBCT and nasal video-endoscopy revealed ostiomeatal obstruction with bone deformity, leading to diagnosis of SSS. Endonasal endoscopic maxillary sinusotomy was performed. Two years later, the patient remained asymptomatic, and a second CBCT exam confirmed a stable condition. This case highlights the role of optimal radiographic interpretation for early diagnosis of maxillofacial alterations in pediatric patients.
慢性上颌窦肺不张（CMA）是上颌窦容积的一种进行性改变，可能导致面部不对称。无症状患者的CMA被称为静默鼻窦综合征（SSS），是一种罕见病症，在儿科患者中尤为少见。本研究报告了一例儿科患者的SSS病例，该患者通过锥形束计算机断层扫描（CBCT）获得了早期诊断。一名正在接受正畸治疗的12岁无症状女性患者，全景X线片显示左上颌窦混浊。临床上，该患者有轻度眼球下转和眼球内陷。CBCT和鼻内镜检查显示窦口鼻道复合体阻塞并伴有骨质畸形，从而确诊为SSS。实施了鼻内镜下上颌窦切开术。两年后，患者仍无症状，第二次CBCT检查证实病情稳定。该病例突出了最佳影像学解读在儿科患者颌面部改变早期诊断中的作用。
