OBJECTIVES We aimed to identify the functional abnormality of sinusitis-affected mucosa by observing the responsiveness of the mucosa to purinergic stimulation after the onset of sinusitis and during the recovery period. We also aimed to identify possible beneficial effects of purinergic agonists on sinusitis. METHODS A rabbit sinusitis model was developed by blocking maxillary ostia. Sinus m...

Address for Correspondence: Dr Anupama Mahajan, Professor & Head, Department of Anatomy, Sri Guru Ram Das Institute of Medical Sciences & Research, Amritsar (Punjab), India. Mobile no. 9815733321 E-Mail: [email protected] Introduction: There has been a significant shift from external and headlight sinus surgery to functional endoscopic sinus surgery (FESS) in the past quarter century. There...

Dear Editor, In the hands of experienced surgeons, the majority of chronic rhinosinusitis patients who undergo endoscopic sinus surgery (ESS) experience significant improvement in symptoms in the first 12 months postoperatively; however, this does not seem to be long-lasting. Three-year outcome analysis indicates that the beneficial effect dissipates over time and that the symptoms continue to ...

Introduction: The horizontal bony canal in the lateral maxillary wall is the site of anastomosis between the arterial branches from the posterior superior alveolar artery (PSAa) and the infraorbital artery. This anatomic structure is known as the ‘alveolar antral artery’.   Materials and Methods: We performed a literature review. The anatomic location of the alveolar antral artery in the latera...

Introduction: When dealing with maxillary sinus pathology, some areas of the sinus remain difficult to examine. In this regard, the pre-lacrimal approach is a minimally invasive technique to reach anterolateral areas of the maxillary sinus while preserving the physiological nasal function.   Materials and Methods: The present study aimed to provide technical hints relate...

Introduction: Comparison of the relationships and distance between maxillary root tips and   the maxillary sinus floor using oral panoramic in the dolichocephalic and brachycephalic compared to mesocephalic individuals. Methods: Oral panoramic images from 300 individuals were analyzed and the relationships and distance between the maxillary root tips and the sinus floor was assessed by qualitat...

introduction: knowledge of the presence of the alveolar antral artery in the lateral maxillary sinus wall is essential for surgeons who operate in this region. the purpose of this study was to investigate the correlation between alveolar antral artery diameter and lateral maxillary bony wall thickness in dentate patients.   materials and methods: thirty five cone-beam computed tomography (cbct)...

Introduction: A hydatid cyst of the head and neck is a very rare condition, even in areas where Echinococcus infestation is endemic.   Case Report: We report a rare case of primary hydatid cyst of the right maxillary sinus in a 40-year-old man. The initial diagnosis of the presence of a cystic mass was the result of physical examination and computed tomography (CT) scan. We resected the cystic ...

Introduction Perforation of maxillary sinus mucous membrane is of the most prevalent complication during open sinus lift surgery. Moreover, such complication can usually be managed by an absorbable membrane. As far as absorbable membranes are concerned, decellularized maxillary sinus mucous membranes, which is an extracellular matrix, can be used as a biologic scaffold and insulating membrane ...
