Functional endoscopic sinus surgery (FESS) has considerably evolved over the past 20 years while minimally-invasive surgery also applies to sinus procedures. Development of new technologies combined with better knowledge of risks has allowed surgeons to achieve improved results in their FESS indications. One of the most difficult areas to visualize using the exclusive endoscopic approach is still the anterior recess of the maxillary sinus. Hence, external approaches, such as the Caldwell-Luc procedure, are still used by many surgeons to ensure visual control of this area in diseases such as fungal balls, mucoceles, inverted papilloma and other tumors...

The objective of the present work was to study topographical and anatomical relationships between the lacrimal passages and the walls of the nasal cavity from the standpoint of the rhinosurgeon. The materials for the study were obtained by examining 15 corpses. It was found out that in 91% of the cases, the natural ostium of the maxillary sinus is localized within 11.6 cm from the lacrimal tubercle. In 62% of the cases, the nasolacrimal passage opens in the region of the vault of the inferior nasal passage as an orifice roughly 0...

A brain abscess may result when dental infection reaches the brain through contiguous anatomic cavities such as the maxillary sinus, the ethmoid sinus and the orbital cavity. It is an important complication and should be treated aggressively. Such treatment would include the excision of the etiological factor, drainage and adjuvant antibiotic therapy. The present case concerns a 23-year-old woman who presented at the General Hospital of Nova Iguaçu with complaints of pain in the right side of the face and was diagnosed with acute sinusitis...

A minimum subantral bone height in the posterior maxilla may require a bone augmentation where a sinus lift procedure is the most commonly used technique, either preceding or simultaneously with the implant installation. While elevating the Schneiderian membrane ruptures are common, possibly resulting in less bone formation. In this paper, we propose the surgical pneumatization of the Schneiderian membrane as a new technique to minimize the risk of such complications. This can be achieved mainly by creating a hole for the immediate and increased passage of air through the Schneiderian membrane and the maxillary sinus wall above the region of augmentation...

Surgical morbidity from open reduction and internal fixation (ORIF) of maxillary sinus wall fracture often surpasses the benefits of ORIF. Hence, the authors devised transnasal endoscopic-assisted reduction of maxillary sinus wall fracture (TERM) without internal fixation as a minimally invasive surgery for maxillary sinus wall fracture. The purpose of this study was to investigate the feasibility of TERM in cadavers and patients. Six cadavers were dissected to evaluate the feasibility of TERM. In addition, 20 patients with maxillary sinus wall fractures who underwent TERM in a tertiary hospital from August of 2013 to December of 2015 were enrolled in this study...

BACKGROUND: Olfactory neuroblastoma (ONB) is a rare malignant neuroectodermal tumor of the nasal cavity. Mixed olfactory neuroblastoma which contains areas of divergent differentiation is even rare. Till date, only 4 cases of mixed olfactory neuroblastomas have been reported. CASE DESCRIPTION: We report the case of a 46-year-old male who presented with the chief complaints of nasal bleeding and nasal obstruction since 4 months. Radiological imaging was suggestive of a large heterogeneous mass in the left superior nasal cavity with extensions into bilateral maxillary, ethmoidal, and sphenoidal sinuses, as well as into the anterior cranial fossa...

Objectives: Pathophysiology of chronic rhinosinusitis (CRS) is very complex and has not yet been clearly understood. To date, various factors have been researched to have relations with the pathogenesis of CRS, such as superantigens and biofilms. Recently, we found an unusual pathological finding in patients with CRS, and we called this new entity as bacteria ball (or bioball). In this study, we analyze the clinical characteristics of bacteria ball occurred in CRS. Methods: This study enrolled consecutive 247 patients with CRS who underwent functional endoscopic sinus surgery from January 2015 to August 2016...

The trigeminocardiac reflex is a brainstem reflex that manifests as sudden hemodynamic dysfunction including bradycardia, hypotension, hypopnea, and gastric hypermotility due to mechanical stimulation of the trigeminal nerve. Here, the trigeminocardiac reflex was part of the initial patient presentation that led to the diagnosis of maxillary adenocarcinoma. A 54-year-old male presented to the emergency department with a two-month history of right upper jaw pain. Vital signs included blood pressure of 68/48 mmHg, heart rate of 55, and oxygen saturation of 85%...
