Endoscopic Treatment of Isolated Sphenoid Sinus Disease in Children

Abstract

In this article, we explore the disease spectrum and clinical characteristics of and the diagnosis and endoscopic approach to treating isolated sphenoid sinus disease (ISSD) in children. To these ends, we review a case series of 19 patients (mean age: 8.1 ± 4.9 years, range: 1.1-15 years, median age: 6.7 years, 13 males, 6 females) who underwent surgical treatment at our hospital for ISSD during the 4 years between 2012 and 2016. The symptoms of pediatric sphenoid sinus disease tend to be variable and nonspecific and include atypical headache, nasal congestion, epistaxis, postnasal drip, snoring, and impaired vision. Headache is the presenting symptom in 42% of patients, but headaches occurred in no specific or typical location. Ten patients underwent preoperative endoscopic examination, and abnormalities in the sphenoethmoidal recess were found in 6 (60%) of these 10 patients. All 19 patients underwent ultra-low-dose paranasal sinus computed tomography (CT) imaging, and 9 patients with suspected tumors or sphenoid mucoceles were further examined by magnetic resonance imaging (MRI). The endoscopic transostial approach was performed in all 19 patients: 16 patients received excision of inflammatory sphenoid sinus disorders and benign tumors, including sphenoid sinusitis, sphenoid sinus mucocele, sphenoid sinus polyp, and ossifying fibroma; 3 patients with suspected tumors received biopsies to detect rhabdomyosarcoma, Langerhans cell histiocytosis, and juvenile xanthogranuloma. No intraoperative or immediate postoperative complications were observed. Children with opacified sphenoid sinus identified by radiographic imaging presented a variety of pathologies. The most common lesions were associated with inflammatory disease. Because the symptoms of pediatric sphenoid sinus disease tend to be variable and nonspecific, CT remains the standard for evaluating sphenoid sinus disease, and ultra-low-dose paranasal sinus CT imaging is recommended and can provide images of equal or better quality compared with those obtained by standard dose CT. In addition, MRI is an essential adjunct in the diagnosis and selection of treatment for suspected tumors of the sphenoid sinus. The endoscopic transostial approach was especially suitable for the management of pediatric benign isolated sphenoid sinus lesions.
