Skull base and sinus surgery has evolved dramatically throughout the past century. It is not long ago that the maxillary sinus would principally be reached via an anterior ap‐ proach through the gingivobuccal sulcus of the oral cavity. The earliest days of endos‐ copy date back to the early 1900s, when Hirschmann used a modified cystoscope to examine the sinuses. Thereafter, modern endoscopy ha...

Antrochoanal polyps are benign lesions originating from the mucosa of the maxillary sinus and gradually prolapse through the medial wall of the maxillary sinus into the nasal cavity increasing in size to the choana and nasopharynx. Surgery is the usual treatment for antrochoanal polyps. We present the case of a 41-year-old woman who presented with a history of a progressive right nasal obstruct...

a large rathke's cyst was marsupialized into the sphenoid sinus of a 45-year old woman who presented with headache, polydipsia, cessation of menses and diplopia. a brief review of cases is presented.

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...

Coronavirus disease 2019 (COVID-19) could be complicated by venous or arterial stroke. However, to the best of our knowledge, there is a limited number cases reported develop cavernous sinus thrombosis (CST) after COVID-19. Herein, we present 61-year-old diabetic male with persistent pain in his right forehead and periorbital region COVID-19 pneumonia diagnosed CST developing diplopia ecchymosi...

Although augmentation of the maxillary sinus floor with autogenous bone grafts has become a well established preimplantology procedure, its effect on the function of the maxillary sinus has not been the subject of prospective human studies. In this prospective study the effects of sinus floor augmentation on maxillary sinus performance were evaluated. Seventeen consecutive patients who were to ...

The anatomical variations of the nasal and sinus paranasal can cause headaches. most common variants have deviated septum, concha bullosa, agger nasi cells. These narrowing osteomeatal complex. Computed tomography was primary modality for evaluating sinuses in diagnosis management. Functional endoscopic surgery generally performed to restore sinuses' drainage ventilation variations. It has been...

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...
