Abstract:

The performance of a maxillary antrostomy through the natural ostium of the maxillary sinus has been debated in the literature over the years. However, much of the argument against middle meatal antrostomy has been based primarily upon animal studies in which there was a patent maxillary sinus ostium. A detailed study was therefore undertaken to evaluate the effects of both ostioplasty and nasal antral window in an animal model with maxillary sinus ostial obstruction. Twenty Pasteurella-free White New Zealand Rabbits underwent unilateral ostial occlusion with Histoacryl®. The sinuses were reex

Abstract:

Locating the maxillary sinus ostium can be a problem in endoscopic middle meatal antrostomy. Patients requiring revision sinus surgery may be found to have the maxillary sinus ostium obstructed, or the previous antrostomy placed in the wrong location. The intricate lateral nasal wall anatomy can be difficult to translate into the two-dimensional endoscopic view. It is therefore understandable how finding the maxillary sinus ostium at times can be tedious. Inability to accurately identify the maxillary sinus ostium may preclude an appropriate middle meatal antrostomy, and predispose the patient

Abstract:

Functional endoscopic sinus surgery concentrates primarily on the removal of ostiomeatal complex disease. When required, maxillary sinus ostioplasty is performed. However, surgical widening of a sinus ostium is contrary to common precepts. A study therefore was performed to reevaluate the effects of antrostomies and of intrasinus mucosal removal. Widening of the natural ostium, a separate antrostomy at some distance from the ostium, or radical mucosal removal was performed on 30 rabbits. Fifteen sinuses were used as controls.

Abstract:

Maxillary sinus ostium may be located anywhere along the ethmoid infundibulum (middle meatus). In rhinosinusal pathology we may find an accessory ostium of the maxillary sinus due to chronic inflammations or after previous endoscopic sinus surgery. Existence of the accessory ostium leads to a recirculation mechanism of sinus secretions and a very difficult to treat rhinosinusal simptomatology. For every patient with this pathology we performed an endoscopic exam of the nose and a rhinosinusal CT scan. Treatment is strictly surgical by creating a unique ostium (consisting of both primary and a

Endoscopic sinus surgery (ESS) is the main surgical approach in the treatment of chronic rhinosinusitis (CRS) after failure of medical treatment.

The aim of this study was to compare computed tomography (CT) findings after preservation or enlargement of the maxillary sinus ostium.

An ostium leading to maxillary sinus apart from the primary maxillary opening is defined as accessory maxillary ostia. Location of accessory maxillary ostia is more advantageous than primary maxillary opening. Accessory maxillary ostia can be utilized to approach the maxillary sinus in cases of difficulty in approaching the primary maxillary opening.

Background Nitric oxide (NO) is produced in significant quantities in the nasal sinuses and is thought to have a beneficial effect on the mucociliary transport of the sinuses and nose and to have significant antibacterial properties that contribute to the health of the sinuses. Recently, the concept of “mini-functional endoscopic sinus surgery” has been introduced where the uncinate is removed without enlargement of the maxillary ostium.

Abstract:

Recirculation of nasal mucus occurs when secretions that have been transported out of the natural maxillary ostium return to the sinus via a surgically created or accessory ostium. Recirculation increases the risk of persistent sinus infection. In this article, we describe a case of mucus recirculation in a patient who had not responded to two previous sinus surgeries for recurrent rhino sinusitis. We also postulate the possibility of ethmoid recirculation.

Abstract:

We have established an experimental model of fungal sinusitis in rabbits to analyze the chronology and the pathogenesis of the development of noninvasive fungal sinusitis due to Aspergillus fumigatus. Thirty-four Pasteurella-free New Zealand white rabbits divided into three groups were included in this study. In the first group (10 rabbits), A fumigatus was inoculated into the maxillary sinus. In the second group (10 rabbits), A fumigatus was inoculated into the maxillary sinus in the presence of a wound in the mucosa. In the third group (14 rabbits), A fumigatus was inoculated into the maxill

AbstractObjectives:Endoscopic sinus surgery has been widely performed to treat nose and paranasal diseases. However, it is difficult to manipulate anterior wall lesions of the maxillary sinus using conventional surgical instruments. This paper presents a method of performing endoscopic surgery for anterior wall lesions of the maxillary sinus, using a 135° reflective CO2 laser.Method:A CO2 laser with a 135° reflective tip on the pipe-guide handpiece and a CO2 laser angulated to the same degree were used. The pipe-guide handpiece with reflective tip was inserted into the nasal cavity and the bas

Abstract:

Background and objectives: The average rate of chronic sinusitis after maxillary implantation was approximately 5.1%. However, the evidence of predictive risk factors for sinusitis after implantation is lacking. The aim of this study was to perform an anatomic study on the maxillary sinus mucosal thickness (MSMT), the distance between the maxillary sinus ostium and sinus floor (MOD), and the MSMT/MOD ratio as a preoperative risk indicator for sinusitis after maxillary dental implantation. Materials and Methods: Between October 2008 and October 2019, all patients referred to the otolaryngology

Abstract:

CBCT significantly impacts dental procedures and has brought significant reforms to our approach to diagnosis and treatment planning despite its limitations in differentiating soft tissues. It is an excellent imaging modality and quickly identifies sinus opacification and provides valuable insight into paranasal sinus pathologies, with considerably lower radiation exposure. The present study aimed to investigate the occurrence of maxillary sinus abnormalities in CBCT scans, identify the frequency, type, and location of these findings, and find the correlation between the distance of periapical

Abstract:

Sometimes the maxillary endosseous implants may migrate into the maxillary sinus, a quarter of them being recorded in maxillary sinus bone grafts. Less frequent it occurs after the occlusal loading or during the prosthetic abutment insertion. The displacement and retention of a dental implant in maxillary sinus causes a chronic sinusitis. One of such infection might be aspergillosis. Clinically the aspergillosis of maxillary sinus may be non-invasive, invasive or allergic. The treatment of non-invasive aspergillosis in immunocompetent individuals consists in surgical removal of infected fungal

Methods: We included all patients who underwent maxillary sinus lift and dental implant procedures between 2014 and 2017. Maxillary sinus imaging findings were extracted from pre-procedural denta

Abstract:

A case of the rare condition Pneumosinus dilatans of the maxillary sinus is presented. This is a rare differential diagnosis of a maxillary disease. The diagnostic imaging features of this condition are described, and a recommendation of views for adequately delineating this disorder is given. Only a few cases of Pneumosinus dilatans of the maxillary sinus are described in the English-language literature, and the precise cause and pathogenesis remain obscure. We performed an enlargement of the maxillary ostium in order to increase the ventilation of the paranasal sinus. In the short-term follo

Abstract:

Background: The ostiomeatal complex (OMC) is an important anatomical structure which contains the maxillary ostium and infundibulum; sinus drainage is performed through this route. Concha bullosa, which is defined as pneumatization of the middle concha, may lead to drainage disorders and sinusitis following alterations in the OMC; hence, the purpose of this study was to investigate the effect of presence of concha bullosa on the infundibulum length and ostium height using cone-beam computed tomography (CBCT).
