Features of the histological structure shell of the maxillary sinus cyst with various diseases of the nasal cavity and paranasal sinuses.

The authors examined and operated on 64 patients with a diagnosis of cystic peritoneal cyst, with various concomitant diseases of the nose and SNP, in order to identify the peculiarities of the histological structure of cysts of percussion. In 18 patients, concomitant disease was allergic rhinitis, in patients with a violation of the aerodynamics of the nasal cavity, 14 patients with recurrent bacterial sinusitis. According to the histological structure, characteristic features of the structure of maxillary sinus cysts were revealed in various diseases of the nose and paranasal sinuses. Based on the histological structure of the maxillary sinus cysts, 3 types of the structure of cysts characteristic of a certain pathology were identified.

Two-way approach to the maxillary sinus: a novel surgical route to approach to maxillary sinus cysts

<h3></h3> Кисты верхнечелюстной пазухи (ВЧП) составляют около 20% среди всех причин оперативных вмешательств на ВЧП. С учетом патогенеза кист наиболее оптимальным хирургическим доступом при их удалении является формирование операционного окна в нижнем носовом ходе. Возможным решением минимизации размеров антростомы в нижнем носовом ходе без ущерба для визуального контроля является применение комбинированного доступа. <h3>ЦЕЛЬ ИССЛЕДОВАНИЯ</h3> Улучшение результатов эндоназального эндоскопического удаления кист ВЧП. <h3>ПАЦИЕНТЫ И МЕТОДЫ</h3> Обследованы 100 пациентов с ретенционными кистами ВЧП, которые в период с 2015 по 2018 г. находились на хирургическом лечении в клинике оториноларингологии «КОРЛ» (Казань). Всем пациентам было проведено хирургическое удаление кисты при помощи шейвера через доступ в нижнем носовом ходе. В зависимости от применяемой модификации доступа пациенты были разделены на три группы: 1-я — пациенты с формированием постоянной антростомы; 2-я — с формированием временной антростомы; 3-я — прооперированные комбинированным доступом. Эффективность предложенного способа оценивали согласно 3 критериям: отсутствие «слепых» зон во время удаления патологического содержимого пазухи; отсутствие рецидива кисты через полгода после оперативного вмешательства; состояние медиальной стенки ВЧП (по данным КТ и эндоскопического осмотра). <h3>РЕЗУЛЬТАТЫ И ЗАКЛЮЧЕНИЕ</h3> Наилучшие результаты были отмечены у пациентов, прооперированных с помощью комбинированного доступа: антростома в нижнем носовом ходе ввиду малых размеров не нарушала физиологию ВЧП, удаление кисты под полным визуальным контролем снизило риск рецидива в послеоперационном периоде.

Bimodal intervention in cystic lesions of the maxillary antrum

&lt;p class="abstract"&gt;Intrinsic or extrinsic cysts are common maxillary antral lesions as there is close proximity between the maxillary antrum and maxillary teeth. Main stay of treatment is complete surgical excision. Endoscopic trans nasal middle meatus corridor and the canine fossa approach facilitate 360-degree access, resection and removal of cystic lesions of the maxillary antrum. Bimodal technique to treat maxillary cysts that have expanded into the maxillary sinus is discussed here. &lt;/p&gt;

Evaluation the quality of life of patient’s with cyst maxillary sinus after endoscopical sinusotomy with different approaches

Topicality: The radical treatment for patients with cysts of the paranasal sinuses is only surgery. There are different approaches used for sinusotomy. Objective: Comparison of the impact on the quality of life of patients performing maxillofacial surgery with different options for surgical approaches. Methods and materials: 110 patients who underwent endoscopic sinus surgery for maxillary sinus cysts removing were examined. They were divided into 3 groups, according to the selected approach: 1st group – sublabial approach (35 people), 2nd group – anthrostomy through the middle nasal meatus (35 people), 3rd group – infraturbinal approach (40 people). To evaluate the quality of life of patients, we used our validated Ukrainian language version of the SNOT-22 questionnaire. Results and discussion: In the early period after maxillofacial surgery there was a significant deterioration in the quality of life of patients, which was more pronounced in groups 1 and 2 and was respectively Ʃsublab 45.3 ± 1.3 and Ʃantrostomy 42.1 ± 1.2 a in patients of group 3 it was significantly lower – Ʃinfr 21.4 ± 0.9 (p &lt;0.05). The total score of ear/facial symptoms on the 3rd day after sublabial sinusotomy was 7.3 ± 1.9 points, which is 1.7 times higher than in the second and 6 times higher than in the 3rd group. According to rhinological symptoms, the greatest impact on the quality of life of patients was observed in patients for whom anthrostomy was chose nasal approach (12.3±1.7 points), which is 1.8 times more than in maxillary microsinusotomy and 2.3 times more than in infraturbinal approach. Conclusions: Infraturbinal approach sinusitis compared with sublabial and anthrostomy according to the SNOT-22 survey has a smaller impact on the quality of life of patients. According to the results of the SNOT 22 survey in the early postoperative period after endoscopic maxillary sinusomy with approach through the antrostomy, there is deterioration in the quality of life of patients mainly due to rhinological complaints, while with sublabial approach – due to ear/facial.

Deep learning object detection of maxillary cyst-like lesions on panoramic radiographs: preliminary study.

This study aimed to examine the performance of deep learning object detection technology for detecting and identifying maxillary cyst-like lesions on panoramic radiography. Altogether, 412 patients with maxillary cyst-like lesions (including several benign tumors) were enrolled. All panoramic radiographs were arbitrarily assigned to the training, testing 1, and testing 2 datasets of the study. The deep learning process of the training images and labels was performed for 1000 epochs using the DetectNet neural network. The testing 1 and testing 2 images were applied to the created learning model, and the detection performance was evaluated. For lesions that could be detected, the classification performance (sensitivity) for identifying radicular cysts or other lesions were examined. The recall, precision, and F-1 score for detecting maxillary cysts were 74.6%/77.1%, 89.8%/90.0%, and 81.5%/83.1% for the testing 1/testing 2 datasets, respectively. The recall was higher in the anterior regions and for radicular cysts. The sensitivity was higher for identifying radicular cysts than for other lesions. Using deep learning object detection technology, maxillary cyst-like lesions could be detected in approximately 75-77%.

HOW CONSERVATIVE CAN WE BE IN THE TREATMENT OF GLANDULAR ODONTOGENIC CYSTS? A CASE REPORT

The glandular odontogenic cyst (GOC) is a rare maxillary cyst with an aggressive, potentially recurrent behavior. Because of such behavior, treating GOC conservatively remains a controversy for many oral and maxillofacial surgeons and oral pathologists. This study reports on a case in which GOC decompression was used with fairly good results in a male patient. After detailed clinical and radiographic examination, we performed an incisional biopsy with simultaneous placement of a decompression device. On receiving the histologic diagnosis of GOC, we decided to keep the decompression for 8 months, which resulted in significant volumetric reduction of the lesion verified through sequential radiographic examination and allowed for curettage of the residual pathologic tissue in a second surgical opportunity. Thus, our opinion is that decompression associated with curettage is a feasible conservative treatment for GOC. Still, longer follow-up is recommended to detect and intervene at the earliest signs of recurrence.

Turbinate stitch: modification of Ahmed’s three-layered flap for oroantral fistulas. A technical note

Computed Tomography (CT) contributes in the functional outcome of Endoscopic Septopasty

Background and objective: Septoplasty is the common surgical procedure performed in nasal septal deviation. Nasal obstruction is the most frequent presentation to the otolaryngologist all over the world with septal deviation. Patients usually presented with headache, epistaxis, ophthalmological, otological, upper and lower respiratory tract infections; and many more. Physical examination, Anterior Rhinoscopy (AR) and Nasal Endoscopy (NE) are considered the gold standard tools to detect septal deviation. Computed Tomography (CT) contributes in the evaluation of the nasal septum, anatomical variants and unveils the associated sinonasal diseases. This study aimed to assess the contribution of CT in endoscopic septoplasty for long term benefits to the patients. Patients and methods: 188 patients of nasal septal deviation were selected from 2015 to 2019 in the Bangladesh Medical and Popular Medical College Specialized Hospital. Age ranged in between 10 year to 70 year of age. CT scanning in both coronal, axial and sagittal sections had been done in all patients after proper history taking, physical examination, anterior rhinoscopy and nasal endoscopy. Endoscopic septoplasty alone and/or other ancillary procedures were performed in all 188 patients under general anesthesia. Results: Among 188 patients, male was 126 (67%) and female was 62 (33%) with a ratio 2:1. Maximum 63 (34%) reported in 31 to 40 year and 54 (29%) was found in 21 to 31 year of age. Hypertrophied Inferior Turbinate (HIT) 74 (39%) and 54 (29%) concha bullosa (CB) were associated with 188 septal deviation. Associated pathologies like maxillary sinusitis 82 (44%) and maxillary antral cyst 78 (41%) were documented. Conclusion: CT scanning detects the abnormal anatomic variants and associated sinonasal pathologies along with nasal septal deviation. Endoscopic septoplasty, correction of the anatomical variants and complete surgical clearance of the sinonasal pathologies can give the patient a long term outcome.

The frequency of the development of a maxillary odontogenic sinusitis acording to various sings and standarts

According to statistics, among sinusitis of various etiologies, the frequency of odontogenic maxillary sinusitis averages from 26 to 40%. This disease affects mainly people of working age and occupies a signiticant place in the practice of a dental surgeon. Aim of the study was to analyze the frequency of occurrence of odontogenic sinusitis in the practice of a dentist- surgeon, tactics and principles of treating patients in an inpatient setting. Materials andmethods. The article presents the results of a retrospective epidemiological analysis of the incidence according to the case reports (70 case reports of inpatients) and records of surgical intervention of the Department of Maxillofacial Surgery in the Ivanovo Regional Clinical Hospital from 2016 to 2019. Results . In total, during the study period, 21 patients addressed chronic odontogenic sinusitis in the exacerbation stage and out of exacerbation, among them 12 (57%) men and 9 (43%) women. This pathology mainly affects men aged 40 to 50 years. The highest percentage of occurrence as a causative tooth was 1 molar - 76 ± 0.25%, 2 premolar, 2 and 3 molars, respectively in 5 ± 0.23%, 9 ± 0.20%and 10 ± 0.26% of cases (p &lt; 0.001). The quantitative indicator of the period of hospitalization of patients in the hospital averaged 9.4 bed days. A total of 22 patients referred to chronic perforated sinusitis, among them 10 (45%) men and 12 (55%) women. Pathology is prevalent mainly among women 5060 years old. When analyzing causal teeth in the development of chronic perforated sinusitis, the highest percentage of occurrence as a causative tooth of 1 molar was also recorded - 67 ± 0.21%, the hospitalization period in the hospital is on average 9.95 bed days. All patients underwent radical maxillary sinusotomy on the right/left, plastic tistula. About 27 maxillary cysts related to the maxillary sinus, 27patients, among them 16 men and 11 women, came. Moreover, 22 (81%) patients had a root cyst, 4(15%) had a follicular from the third molar, and 1 (4%) had a malformation. The examined patients had Hxed teeth whose roots stand in the cavity of the cyst. Cysts occur in patients at almost any age, more often men suffer, the hospitalization period in the hospital averages 8.8 bed days. Conclusions . Women aged 50 to 60 years are more likely to suffer from chronic perforated sinusitis, and men from 30 to 60 years old are most prone to the formation of cysts that have grown into the maxillary sinus. In most cases, for all 3 nosological forms of the disease, the tirst molar was the causative tooth. When the maxillary sinus was involved in the inflammatory process, a radical sinusotomy was predominantly performed, significantly reducing the frequency of relapses.

Treatment tactics the maxillary sinuses cysts of patients to whom dental implantation is planned

Introduction: The modern strategy of the treatment of maxillary sinus cysts provides for the surgery in cases of clinically significant cysts, and in other cases – observation. When performing sinuslifting, cysts of the maxillary sinuses are a risk factor for complications. The objective of the study: to increase the effectiveness of treatment of patients with cysts of the maxillary sinus, who are scheduled for dental implantation. Material and Methods: The results of dental implantation in 124 patients with maxillary sinus cysts were studied in order to substantiate the feasibility of removing, before sinuslifting, not only cysts accompanied by complaints but also those located at a distance of 10 mm from the planned implantation site. Results: The frequency of Schneider membrane perforation during sinuslifting was observed in 12.1% of patients. Removing the cysts located within 10 mm from the dental implantation site before sinuslifting reduced the frequency of Schneider membrane perforations by 2.7 times and other complications by 3.7 times. Conclusion: When determining the treatment tactics for patients with maxillary sinus cysts to whom dental implantation is planned, the localization of the cyst in the sinus and its relationship between the ostiomeatal complex and the site of dental implantation should be taken into account. Removal of cysts of the maxillary sinus, located above the site of the planned dental implantation and within 10 mm from it, reduces the frequency of sinuslifting complications.

Performance of deep learning object detection technology in the detection and diagnosis of maxillary sinus lesions on panoramic radiographs.

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. 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). 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. Deep learning could reliably detect the maxillary sinuses and identify maxillary sinusitis and cysts of the maxillary sinus regions. 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%.

Calcified shell in the maxillary antrum: An interesting imaging characteristic of an antral cyst

The proximity of the maxillary antrum to the maxillary alveolus and teeth leads to many antral lesions being diagnosed by an oral physician. Antral lesions may be intrinsic pathologies arising from the sinus mucosa itself or as a result of extrinsic odontogenic or non-odontogenic lesions arising from the maxillary alveolus or teeth. We present an interesting case of a 41-year-old lady with a maxillary swelling which clinically appeared as a maxillary cyst, radiologically as a calcified shell in the antrum and eventually the histology showed it was a maxillary antral cyst.

Unilateral diseases of the maxillary sinus

Unilateral diseases of the maxillary sinus are among the most common rhinologic diagnoses. The diversity of these diseases can represent achallenge for the treating physician. The spectrum ranges from harmless maxillary sinus cysts that seldom require treatment, to highly aggressive malignant tumors. Special attention should be given to the management of inverted papilloma. These benign tumors are characterized by high recurrence rates and the potential for malignant transformation. The key to minimizing recurrence is precise surgical intervention. Other unilateral maxillary sinus diseases such as the antrochoanal polyp and the fungus ball (aspergilloma) are also discussed in depth.

THE EFFECT OF PLATELET RICH-FIBRIN WITH AND WITHOUT AUTOGENOUS BONE GRAFT ON BONE REGENERATION FOLLOWING ENUCLEATION OF MAXILLARY CYSTS

Introduction: Reconstruction of bony defects represents a challenging problem for the surgical community. Autologous bone grafting involves utilizing bone obtained from the same individual receiving the graft. Bone can be harvested from the mandibular symphysis (chin area). Autologous platelet rich-fibrin (PRF) is considered to be a healing biomaterial, which has been widely used for accelerating soft and hard tissue regeneration. The use of bone graft in combination with platelet rich-fibrin helps in rapid bone regeneration when compared to natural healing. Objectives: is to compare the effect of platelet rich-fibrin with and without autogenous bone graft on bone regeneration following enucleation of maxillary cysts. Materials and methods: Twenty-one patients with maxillary cysts had been treated with autogenous bone graft with platelet-rich fibrin versus platelet rich-fibrin without autogenous bone graft following cyst enucleation, and the follow up was done for 6 months using Cone Beam Computerized Tomography (CBCT) to evaluate bone regeneration in the defect site. Results:All groups showed increasing in bone density. Group A showed the best results with a mean 330.71, while Group B showed results with a mean 184. Group C showed results with a mean 117.71. Conclusions: PRF can be considered a healing biomaterial, as it features all the necessary parameters permitting bone regeneration without any adverse reaction. The addition of autogenous bone graft to PRF accelerates the regenerative capacity of bone. They give a predictable clinical and radiographic evidence of bone formation and faster healing than using PRF alone.

Effect of Biphasic Bone Graft Material (BGM) in combination with autologous platelet-rich fibrin (PRF) on bone regeneration in an odontogenic maxillary cyst: A randomized controlled clinical trial

ABSTRACT Objectives: The purpose of this study was to assess the effect of SYMBIOS® biphasic bone graft material (BGM) in combination with autologous platelets rich fibrin (PRF) on the bone regeneration in the treatment of odontogenic maxillary cysts. Materials and methods: A total of twenty eight patients suffering from large maxillary odontogenic cysts were treated by enucleation and were randomly assigned into two groups. Each group was formed of fourteen patients. The bony defects were grafted by a combination of SYMBIOS® and PRF in group (A) and application of SYMBIOS® alone in group (B). Postoperative clinical and radiographic follow-up were performed. Pain and swelling scores were measured using VAS at 6 weeks postoperative follow up, while bone density of the bony defects were measured using cone beam computerized tomography (CBCT) at 9 months post-operative follow up. Results: Accelerated wound healing was observed in all cases without any signs of postoperative complications. On the 9th month post-operatively the bone density was increased by 45.03% in group (A) where is the results of group B. Conclusion: SYMBIOS®/PRF combination accelerated bone healing and improved the quality and quantity of regenerated bone rather than SYMBIOS® alone.
