In order to analyze whether ultrasonography with a reasonable degree of confidence can replace radiography in the diagnosis of sinusitis, 138 patients with clinical signs of sinusitis were examined with both methods. It was found that maxillary sinus fluid was recognized ultrasonographically with a confidence that increased with the amount of fluid, judged from radiographic examinations. In a sub-group of 45 cases, fluid confirmed by maxillary sinus puncture was detected by ultrasonography in 35/45 sinuses (78%) and by radiology in 38/45 sinuses (84%). In patients with radiographically normal maxillary sinuses, the correlation to ultrasound was good. However, mucosal swelling and polyps or cysts observed at radiography were poorly demonstrated by ultrasonography. In addition, the ultrasound method was not reliable for frontal sinus diagnosis. It was concluded that ultrasonography can be recommended in maxillary sinusitis for follow-up of treatment and as a screening method before sinus radiography.

Odontogenic infections can directly trigger maxillary sinusitis. CBCT is an excellent choice for precise examination of maxillary sinuses and hard tissues within the oral cavity. The objective of this retrospective and the cross-sectional study was to analyze the influence of odontogenic conditions on the presence and intensity of maxillary sinus mucous membrane thickening using CBCT imaging. Moreover, periodontal bone loss and anatomic relationship between adjacent teeth and maxillary sinuses were assessed to evaluate its possible impact on creating maxillary thickening. The study sample consisted of 200 maxillary sinuses of 100 patients visible on CBCT examination with a field of view of 13 × 15 cm. The presented study revealed a significant influence of periapical lesions, inappropriate endodontic treatment, severe caries, and extracted teeth on the presence of increased thickening of maxillary sinus mucous membrane. In addition, an increase in the distance between root apices and maxillary sinus floor triggered a significant reduction of maxillary sinus mucous membrane thickening. The presence of periodontal bone loss significantly increases maxillary sinus mucous membrane thickening.

AbstractThe treatment of chronic maxillary sinusitis aims at the re-establishment of proper aeration and drainage of the antrum. Middle meatal antrostomy offers ventilation and clearance of the antrum and has anatomical, physiological, physical and pathological basis.This work included 66 cases of chronic maxillary sinusitis, for whom 94 operations of endoscopic middle meatal antrostomy were performed (38 unilateral and 28 bilateral procedures). Any associated anatomical variations and/or pathological abnormalities at the ostiomeatal area were dealt with. Follow-up of these cases for periods ranging from four to 12 months showed that 95.5 per cent of the cases experienced subjective improvement. Endoscopically 96.8 per cent of the antrostomies were patent and 94.7 per cent of the maxillary sinuses were clear and regained healthy mucosa. The author concluded that middle meatal antrostomy, when done endoscopically, is a safe procedure with good results

Abstract Background Antrochoanal or Killian polyp is a rare polyp of the maxillary sinus in adults. It is generally unilateral, implanted on the lateral wall of the maxillary sinus upon the uncinate process. Bilateral cases are very rare; only 14 cases have been cited from 1980 to 2020. Case presentation Our patient presented with a complete bilateral nasal obstruction, this symptom persisted for more than 10 years, with a perceived prolapse in his throat in the last 4 months. Anterior rhinoscopy showed a polyp that took up the totality of his nasal vestibule. Posterior rhinoscopy showed a polyp bulging behind the uvula. The challenge in this case is related to diagnosis decision; conditions with the same clinical presentation are several. Diagnosis was established through the clinical, radiological, and endoscopic aspects, and confirmed by histological findings. Management was obtained through functional endoscopic sinus surgery; no recurrence was noted in the 12-month follow-up, and clinical signs had completely subsided. Conclusion Diagnosis in bilateral forms of Killian polyp is perplexing; however, its management is generally simple, with excellent outcome. We report the case of the 15th patient along with a systematic literature review discussing bilateral Killian polyps, illustrated by a rare case of enormous bilateral antrochoanal polyps.

During the surgical removal of maxillary molars, tooth or fragment displacement into the maxillary sinus may occur. The presence of foreign bodies inside these cavities leads to complications such as mucoceles, cellulitis, oroantral fistulae and maxillary sinusitis, to prevent the arise and worsening of complications, these events must be addressed in an early stage. This article aims to report the removal of a tooth root from the maxillary sinus, through the modified Caldwell-Luc (CLM) approach and describe the current indications for the Caldwell Luc technique. It reports an upper third molar surgery in which a patient had the distal root of the left superior third molar displaced into the maxillary sinus, later showing signs of sinus opacification and loss of patency of the maxillary ostium obstructed by the root. After antibiotic treatment, the root was recovered through the CLM technique by local anesthesia, without complications. Foreign bodies in the maxillary sinuses must be urgently addressed, avoiding the development of infectious conditions, the CLM approach is the choice approach to manage these complications by a simple and safe way.

The purpose of the study was to give a clinical evaluation of the effectiveness of endonasal blockade of the nasopalatine nerve in different ways during radical maxillary sinusotomy in dental patients. Materials and methods. Clinical observations were performed in 50 patients diagnosed with chronic odontogenic maxillary sinusitis. Radical maxillary sinusotomy was performed under local potentiated anesthesia. All patients underwent anesthesia on the maxilla according to classical methods. Patients, depending on the methods of endonasal blockade of the nasopalatine nerve, were divided into two clinical groups: the main (24 people) and the comparison group (26 people). Patients of the main group underwent endonasal blockade of the nasopalatine nerve at the site of its branch from the pterygopalatine ganglion. In patients of the comparison group, the blockade of this nerve was performed before its entry into the incisal canal. The effectiveness of anesthesia was evaluated for clinical and autonomic manifestations of pain stress. Results and discussion. During the removal of polyps and pathological granulations from the mucous membrane of the maxillary sinus in patients of the main group there was no pain, no emotional-motor and autonomic manifestations of pain stress, which confirmed the effectiveness of the endonasal method of anesthesia of the nasopalatine nerve. In patients of the comparison group during similar surgical manipulations the full effect of local anesthesia was achieved in 50.0% of cases (χ2 – 8.065, р = 0.005). These were patients who had hypopneumatized or moderately pneumatized types of maxillary sinuses. The rest of the patients during the operation had emotional – motor and autonomic manifestations of pain stress during the removal of pathologically altered mucous membrane located on the medial wall of the maxillary sinus. Conclusion. Complete anesthesia of the mucous membrane, maxillary sinus, regardless of the degree of its pneumatization is achieved during the usage of endonasal blockade of the nasopalatine nerve at the site of its branch from the pterygopalatine ganglion during radical maxillary sinusotomy in dental patients. Anesthesia of the nasopalatine nerve in the lower nasal passage, before its entry into the incisal canal, allows painless surgery only in patients with hypopneumatized maxillary sinuses and in most patients with moderate pneumatization

Cultures obtained from the middle meatus have been used frequently in the past to direct therapy in patients with acute maxillary sinusitis. However, no convincing data have been published to indicate that middle meatal cultures accurately represent the bacterial flora within the maxillary sinus. The hypothesis of this experiment is that bacteria obtained by directed middle meatal cultures qualitatively and quantitatively correlate with cultures taken by maxillary sinus puncture. Acute sinusitis was induced by injecting 108 colony-forming units of bacteria directly into the maxillary sinuses of rabbits in which the ostia were occluded with cotton packs. Eight animals were injected with Staphylococcus aureus, eight with Haemophilus influenzae, and eight with Streptococcus pneumoniae. The packs were removed after 3 days, and specimens were obtained from the middle meatus in the region of the maxillary sinus ostium, and from the maxillary sinus, 1 day later. The contralateral maxillary sinuses of six of the animals were injected with normal saline and served as controls. There was a 100% correlation rate between cultures of specimens obtained from the maxillary sinus and from the middle meatus in all 24 animals. In addition, the quantitative counts from the middle meatus and the maxillary sinus correlated. Control animals showed no bacterial growth from either the middle meatus or the maxillary sinus. These results show that, in an animal model of acute sinusitis, cultures of specimens from the middle meatus reflect the contents of the maxillary sinus.

Objective: The first aim of this study was to determine the performance of a deep learning object detection technique in the detection of maxillary sinuses on panoramic radiographs. The second aim was to clarify the performance in the classification of maxillary sinus lesions compared with healthy maxillary sinuses. Methods: The imaging data for healthy maxillary sinuses (587 sinuses, Class 0), inflamed maxillary sinuses (416 sinuses, Class 1), cysts of maxillary sinus regions (171 sinuses, Class 2) were assigned to training, testing 1, and testing 2 data sets. A learning process of 1000 epochs with the training images and labels was performed using DetectNet, and a learning model was created. The testing 1 and testing 2 images were applied to the model, and the detection sensitivities and the false-positive rates per image were calculated. The accuracies, sensitivities and specificities were determined for distinguishing the inflammation group (Class 1) and cyst group (Class 2) with respect to the healthy group (Class 0). Results: Detection sensitivities of healthy (Class 0) and inflamed (Class 1) maxillary sinuses were 100% for both testing 1 and testing 2 data sets, whereas they were 98 and 89% for cysts of the maxillary sinus regions (Class 2). False-positive rates per image were nearly 0.00. Accuracies, sensitivities and specificities for diagnosis maxillary sinusitis were 90–91%, 88–85%, and 91–96%, respectively; for cysts of the maxillary sinus regions, these values were 97–100%, 80–100%, and 100–100%, respectively. Conclusion: Deep learning could reliably detect the maxillary sinuses and identify maxillary sinusitis and cysts of the maxillary sinus regions. Advances in knowledge: This study using a deep leaning object detection technique indicated that the detection sensitivities of maxillary sinuses were high and the performance of maxillary sinus lesion identification was ≧80%. In particular, performance of sinusitis identification was ≧90%.

Introduction As experience grows with in-office balloon sinus dilation (BSD) procedures, technique modifications will evolve to meet specific needs. The major disadvantage with the maxillary BSD procedure is that the intact uncinate process prevents visualization of and instrument access into the maxillary sinus both intraoperatively and postoperatively. Combining a partial or complete uncinectomy procedure with maxillary BSD could be beneficial in selected patients with certain maxillary sinus problems. Objective The primary objective of this study was to see if, in selected patients, combining an uncinectomy and maxillary sinus BSD together allowed visualization of and access to the maxillary sinus cavity at the time of the procedure and at follow-up visits. Method A chart review was completed for BSD cases performed from 2013 through mid-2015 identifying patients who underwent partial or complete uncinectomy with in-office maxillary sinus BSD. A total of 14 patients were identified, with 26 sinuses treated. The data collected included: difficulty or problems in performing an uncinectomy with the maxillary sinus BSD; visualization and access to the maxillary sinus cavity both intraoperatively and at follow-up visits; and occurrence of complications or late adverse sequelae. All patients completed a minimum 6-month follow-up. Results Combined uncinectomy and maxillary sinus BSD procedures were easily completed for all patients without complications, and no late adverse sequelae were encountered. The maxillary sinuses could be visualized and accessed, if needed, intraoperatively and at all follow-up visits. Conclusions In selected subsets of maxillary sinus conditions this procedure modification can provide significant benefits. A case is presented for illustration.

Background In patients with chronically diseased maxillary sinuses, poor mucociliary clearance may result from long-standing inflammation or scarring from previous surgery. This subset of patients often has persistent sinus disease despite medical therapy and adequate antrostomy. Endoscopic maxillary mega-antrostomy (EMMA) is a mucosal sparing technique that facilitates mucus clearance and sinus irrigation in terminally dysfunctional maxillary sinuses. EMMA involves extending the antrostomy through the posterior half of the inferior turbinate down to the floor of the nose, creating a significantly enlarged antrostomy. This study describes our results of EMMA in recalcitrant maxillary sinusitis. Methods A retrospective review was performed of patients who underwent EMMA for recalcitrant maxillary sinusitis between July 2005 and September 2007. We studied diagnoses, comorbid factors, clinical efficacy, revision rate, and complications. Results Twenty-eight patients (average age, 48 years) underwent 42 EMMAs for recalcitrant maxillary sinusitis. Average follow-up was 11 months. All patients had previous maxillary sinus surgery (mean = 2.3). Relevant comorbid factors included prior Caldwell-Luc or maxillofacial surgery (16/42), cystic fibrosis (11/42), asthma (11/42), and IgG deficiency (3/42). The most common symptoms reported were facial pain/pressure and purulent rhinorrhea. At the time of the most recent postoperative examination, 74% of patients reported complete resolution of symptoms while 26% reported partial symptomatic improvement. There were no complications and the revision rate was 0%. Conclusion Maxillary sinuses that appear to be terminally diseased may be rehabilitated surgically without the need for surgical stripping. EMMA is an effective and safe treatment option for the management of recalcitrant maxillary sinus disease.

Background and Objectives For maxillary sinus diseases, it is not easily determined whether it is of the sinus or dental origin as the root of a tooth is located in the maxillary sinus; hence the need to find the pathologic origin for better clinical results. The purpose of this study was to define the characteristics of patients who had needed to consult both a dentist and an otolaryngologist with respect to the diagnosis and management.Subjects and Method Thirty-one patients who visited the department of dentistry and ENT between 2014 and 2018 were included in the study. Patients with dental implant sinusitis were excluded. We restrospectively reviewed the medical records for chief complaints, assessment, diagnose, treatment, and prognosis of the patients.Results Of 31 patients, 13 patients were diagnosed with odontogenic rhinosinusitis (ORS), 5 with postoperative cheek cyst (POCC), 2 with radicular cyst without ORS, 7 with sinusitis, and 4 with other diseases. Thirteen patients underwent combined operation and 5 at each department. Follow-up periods was about 6.5 months. There was no disease recurrence except one patients with POCC.Conclusion There needs to be an active consultation with the dentistry department in case of unilateral sinusitis and past history of dental treatment temporally or when patients show positive findings in CT.
