Effect of sinus opacification on the severity of obstructive sleep apnea.

Purpose: The association between rhinosinusitis and obstructive sleep apnea (OSA) remains unclear. Here, we aimed to elucidate the association between sinus opacification and OSA severity.

Methods: Patients with snoring problems who visited our clinic from April 2018 to December 2020 were retrospectively enrolled.

Fungus Ball of the Maxillary Sinus Presenting With Epiphora.

The authors report a case of fungus ball of the maxillary sinus with bone erosion presenting with epiphora, which was diagnosed after treatment failure using silicone intubation for nasolacrimal duct obstruction. Symptoms of sinus fungus ball are similar to those of chronic bacterial rhinosinusitis, although occasionally asymptomatic. To our knowledge, epiphora has never been reported as a symptom of sinus fungus ball.
