A 35-year-old male complained of recurring headache and nasal obstruction over a 4-year period. A Caldwell-Luc operation was subsequently performed on the left maxillary sinus and a greenish appearing material was removed. Microscopic examination of the tissue specimen showed a granulomatous tissue with typical cholesterol clefts and inflammatory changes consistent with chronic sinusitis. This entity is presented and reviewed.
Adenoid cystic carcinoma (ACC) rarely occurs in the nasolacrimal duct (NLD), and when it does, it has nonspecific manifestations. To the best of our knowledge, one case of ACC in the NLD has been reported in the literature. Herein, we report a second case of ACC in the left NLD, concerning a man in his late 60s.
Objective: Aim: To evaluate the role of maxillary bone inflammation in the formation of MSCs through the comprehensive assessment of histological and radiological research results and the determination of receptor activator of nuclear factor kappa-B (RANKL) in tissue homogenates, nasal secretions, and blood plasma.
Patients And Methods: Materials and Methods: We included 25 patients aged 20 to 65 with maxillary sinus cysts. We analyzed computed tomography and used enzyme-linked immunosorbent assay with human TNFSF11 (RANKL) in biological samples.
Introduction: When a pilot is referred for nasal polyposis, his/her flight fitness may be questionable. The objective of this retrospective study was to describe a case series of barotrauma in a pilot population exhibiting nasal polyposis and to discuss the decisions about their flight fitness.
Methods: There were 17 pilots with nasal polyposis who were referred to the Head and Neck Department of the National Pilot Expertise Center.
Background: The infrazygomatic miniscrew implants (IZC-MSI) serve as innovative temporary anchorage devices placed parallel to the roots of molars in the infrazygomatic crest region, leveraging their extra-radicular location to support the en masse distalization and intrusion of the maxillary dentition. The efficacy and stability of these screws are crucial for their application in contemporary orthodontic practices.
Objectives: This systematic review aimed to estimate the success rate and factors affecting the stability of IZC-MSI.
Sinonasal inverted papilloma (SNIP) is less malignant and usually occur in the maxillary sinus. However, cases invading the pterygopalatine fossa are extremely rare. In this article, we describe a rare case of a man in his early 60s who presented with left nasal congestion, headache, epistaxis, and facial numbness.
