INTRODUCTION The medial maxillary sinus roof is a ridge formed by the superior margin of the maxillary sinus antrostomy. The posterior wall of the maxillary sinus is always included in operative fields. OBJECTIVE To perform a radiologic study assessing the utility of the medial maxillary sinus roof and the posterior wall of the maxillary sinus as fixed landmarks for providing a safe route of ...

Cholesterol granuloma (CG) is a tissue reaction in response to the accumulation of cholesterol crystals rarely found in the maxillary sinus. The etiopathogenesis of maxillary sinus CG remains unclear. We reviewed the literature and added two new reports of cholesterol granuloma in maxillary sinus related to endodontically treated maxillary posterior teeth. The first report refers to a 45-year-o...

Sinusitis is inflammation of the sinuses, which are air-filled cavities in the skull This inflammation leads to blockade of the normal sinus drainage pathways which in turn leads to mucus retention, hypoxia, decreased mucociliary clearance, and predisposition to bacterial growth it is characterized by headache Postnasal drip Face and eye pain Pain over the bridge of the nose sometimes tinged wi...

Maxillary sinus hypoplasia (MSH) is an uncommon abnormality of paranasal sinuses noted in clinical practice. Computed tomography (CT) scan helps in diagnosing the anomaly along with any anatomical variation that may be associated with it. MSH is usually associated with other anomalies like uncinate process hypoplasia. Three types of MSH have been described. Type 1 MSH shows mild maxillary sinus...

INTRODUCTION Choanal polyps are a benign pathology arising in the sinusal mucosa and entering the nasal fossa heading for the choana. It is a unilateral condition mainly affecting young people. It must be surgically removed, with exeresis of both the nasal and the sinusal lesions. MATERIAL AND METHOD A retrospective review has been made of 51 patients treated for choanal polyp at our centre. ...

PURPOSE This study investigated the relationship between the roots of the maxillary molars and the maxillary sinus using cone beam computed tomography (CBCT), and measured the distances between the roots of the maxillary molars and the sinus floor as well as the thickness of the bone between the root and the alveolar cortical plate. MATERIALS AND METHODS The study sample consisted of 83 patie...

objectives: to compare the thickness of the lateral wall of the maxillary sinus in individuals with and without teeth to determine if extraction of the teeth can lead to a significant reduction in the thickness of the maxillary sinus lateral wall or not. patients and methods: in a retrospective study on fifty patients with an edentulous space, the thickness of the lateral wall of the maxillary ...

AIM The study aimed to investigate the proximity of maxillary posterior teeth roots to maxillary sinus and measure the distance of maxillary posterior teeth roots and the sinus floor as well as the thickness of bone between the roots and alveolar cortical bone using Denta scan®. MATERIALS AND METHODS The study samples include Denta scan® images of fifty patients with normally erupted bilatera...

Introduction Functional endoscopic sinus surgery has a long-term high rate of success for symptomatic improvement in patients with medically refractory chronic rhinosinusitis. As the popularity of the technique continues to grow, however, so does the population of patients with postsurgical persistent sinus disease, especially in those with a large window for ventilation and drainage. In additi...

BACKGROUND We report a rare case of fatty tissue within the maxillary sinus in a 21-year-old woman, with a history of several previous punctures of the maxillary sinus. CASE PRESENTATION Clinical data of the patient was analysed retrospectively. The patient presented with symptoms of left-sided chronic maxillary sinusitis and had undergone several punctures of the left maxillary sinus 18 mont...
