Aim:Some obstructive sleep apnea (OSA) patients may have mandibular retrognathia (ANB > 4.7° and SNB < 76.2°). Currently, there are no studies that have compared the effectiveness of continuous positive airway pressure (CPAP) versus mandibular advancement device (MAD) in severe OSA patients with mandibular retrognathia. We explored the efficacy of CPAP versus MAD for the treatment of severe OSA patients with mandibular retrognathia.Methods:A total of 105 patients were enrolled. Outcomes were assessed by using polysomnography,...

Primary heterotopic meningiomas are lesions that are not associated with a cranial nerve foramen, vertebral canal, or intracranial structure. The most common histopathological subtype is meningeal epithelioma. In clinical practice, primary heterotopic nasal meningioma occurs relatively rarely, and its most common pathological type is psammomatous meningioma, whereas nasal fibrous meningioma is infrequent. In our case, a 31-year-old male patient was admitted to the hospital with “progressive nasal obstruction on the right side for half a...
