Background: Craniopharyngiomas have traditionally been treated via open transcranial approaches. More recent, endoscopic endonasal approaches have been increasingly used; however, there has been limited evaluation of long-term outcomes for this approach. Methods: A retrospective review was performed to analyze patients with pediatric craniopharyngioma undergoing endonasal endoscopic resection from 2012 to 2020. Demographic information, clinicopathologic factors, and outcomes including follow-up and recurrences were analyzed. Results: All 42 patients, with a mean age of 8.0 years, were included. The median follow-up time was 49 months. Mean tumor diameter was 3.6 cm. All of the tumors had sellar and suprasellar components. The most common presenting symptoms were headaches (64.3%), visual changes (59.5%), and nausea/vomiting (38.1%). Most patients (73.3%) had resolution of their presenting symptoms by their first postoperative visit. Vision improved or remained normal in 69.0% of patients. Postoperatively, incidence of panhypopituitarism or diabetes insipidus developed in 89.7% and 77.8% of patients, respectively. The postoperative cerebrospinal fluid leak rate was 7.1%. The recurrence rate was 9.5%. Conclusion: Endoscopic endonasal resection for pediatric craniopharyngiomas can achieve high rates of resection with low rates of disease recurrence when compared with the outcomes of open transcranial resection reported in the literature. However, hypothalamic-pituitary dysfunction remains a significant postoperative morbidity in both approaches.

Silent sinus syndrome refers to a constellation of spontaneous and progressive enophthalmos and hypoglobus in the setting of asymptomatic ipsilateral maxillary sinus atelectasis. Although its exact etiopathogenesis is not completely understood, obstruction of the ostiomeatal complex appears to be the inciting event. Most of the reported cases of silent sinus syndrome involve one maxillary sinus. Only a handful of true bilateral silent sinus syndrome cases have been reported in the literature. The aim of this report is to present a case of metachronous bilateral maxillary silent sinus syndrome and its natural progression. Also included is a review of the literature on ethmoidal, frontal, and bilateral maxillary silent sinus syndrome.

Background Orbital, intracranial, and osseous extra-sinus complications can arise from bacterial or fungal sinusitis. Odontogenic sinusitis (ODS) can cause extra-sinus complications, but its prevalence remains poorly characterized. Objective To determine the frequency of ODS as a cause of operative extra-sinus infectious complications and describe clinical features of all complicated sinusitis cases. Methods A multi-institutional retrospective review was performed on all operative sinusitis-related extra-sinus complications from 2011 to 2020. ODS was diagnosed by sinus computed tomography (CT) and dental evaluations when available. Demographics, complication types, sinusitis etiologies, and various clinical features were analyzed. Results Forty-five patients were included (mean age 55.5 years, 56% male). Of the extra-sinus complications, 40% were orbital only, 22% intracranial only, 13% osseous only, and 25% involved combined complications. The 2 most common causes of extra-sinus complications were ODS (40%) and mucopyocele (27%). When invasive fungal etiologies were excluded, and only unilateral maxillary opacification on CT was considered, nearly 60% of extra-sinus complications were due to ODS. Unilateral maxillary sinus opacification on CT was present in 100% of complicated ODS compared to 44% of nonodontogenic cases, and oral anaerobes were only identified in ODS cases. No complicated ODS patients underwent dental interventions during hospitalization. Conclusion ODS was the most common cause of operative extra-sinus infectious complications. Clinicians should consider ODS high on the differential diagnosis of all patients presenting with complicated sinusitis, especially when sinusitis is unilateral and invasive fungal infection is not suspected.
