ObjectiveSilent sinus syndrome (SSS) and chronic maxillary atelectasis (CMA) are unusual conditions having subtle symptoms with a possible progressive evolution. They are particularly infrequent in the pediatric population. Our objective was to review our experience with pediatric patients having SSS or CMA, and to review all cases involving patients under 14 years of age reported in the literature.MethodsA retrospective review of 6 patients diagnosed with SSS or CMA surgically treated from 2001 to 2014 was carried out. All cases reported in literature were reviewed.ResultsAll patients underwent functional endoscopic sinus surgery with an improvement in symptoms after surgery. Diplopia disappeared in two patients who presented with it and enophthalmos improved in all five patients presenting with it. Only one patient out of four presenting with headache had a persistence of the symptoms which were, however, milder than they had been preoperatively. Endoscopic examination demonstrated a reventilated maxillary sinus in all cases. A radiological examination at follow-up was performed in 5 cases and demonstrated a reexpansion of the maxillary sinus as compared to the contralateral side in all patients except one. None of the patients required an orbital floor reconstruction. Eleven similar cases reported in the literature were analyzed and compared.ConclusionEndoscopic uncinectomy and middle meatal antrostomy should be the treatment of choice for these conditions in patients presenting with enophthalmos and/or hypoglobus and symptoms related to it. Orbital floor reconstruction should be performed as a delayed procedure only in selected cases. Chronic maxillary atelectasis or SSS should be considered as a possible cause of persistent headache of unknown origin in pediatric patients.
