“…CBCT unveiled a homogeneous “dome-shaped”/“rising sun” solitary radiopaque mass located at the floor of the right maxillary sinus, precisely above the region of the planned sinus lift ( Figure 1 C). The radiological image, class III B by Di Girolamo classification [ 6 ], combined with the absence of symptoms, suggested a mucous retention cyst or pseudocyst of the maxillary antrum [ 2 ]. Although in such cases, Di Girolamo et al suggest endonasal sinus surgery (ESS) before sinus lift due to possible difficulty in sinus floor elevation and risk of ostium obstruction, our article provides a solution to avoid ESS and prolonged treatment without compromising the sinus lift procedure and the final outcome.…”

Objectives: A mucous retention cyst is a common, asymptomatic lesion that may cause complications during or after the sinus lift procedure. The goal of this study is to assess the effectiveness of the Croco Eye Technique (CET), which allows simultaneous excision of the cyst and sinus floor elevation. Methods: The technique was thoroughly described in two versions, and the group of 33 patients was analyzed. Patients who qualified for this procedure had insufficient alveolar ridge height, and their CBCT showed radiological images typical for retention cysts. Analyzed parameters included the version of CET, demographic data, anatomical parameters, intraoperative complications, recurrence of the cyst, success rate of the sinus lift and implants, and the follow-up period. Results: Out of the 33 cases, 9 were of the primary version (27.27%) and 24 of the final version (72.73%). The average height of a retention cyst was 24.05 mm, with the average alveolar ridge height of 1.86 mm. In three cases (9.09%), implants were placed immediately. The prevalence of uncontrolled Schneiderian membrane perforation was reduced from 55.56% to 4.17% between the primary and final versions. The cyst’s recurrence rate was 3.13%. The implant survival rate was 100%. The mean follow-up period was 48.625 months (max 110 months). Conclusions: The Croco Eye Technique, despite the perforation of the Schneiderian membrane, enables successful sinus lift and implantation with a success rate of 100%. Excision of the retention cyst, which is the cause of perforation, allows for limiting the risk of the cyst’s recurrence.

“…Previous sinus pathologies were evaluated according to the radiological classification of class I to class IV of Di Girolamo et al on the thickness and pathology of the Schneiderian membrane. 11 A total of eight implants (AnyRidge; MegaGen, Seoul, S. Korea) with diameters Ø 4.0 / 4.5 mm and lengths of 10 and 11.5 mm were placed simultaneously with the PAC protocol, using a circular tissue punch without a flap (flapless technique).…”

Objectives A new protocol with albumin-concentrated growth factor (CGF) is investigated through Piezosurgery as a minimally invasive alternative to sinus-floor-augmentation that is associated with high morbidity and high incidence of sinusitis. Materials and Methods The clinical sample consists of five patients (three men and two women) with an average age of 53.75 ± 3.59 years and a mean height of 3.7 ± 1.22 mm of residual bone. The Piezo-Alb-CGF protocol consists of a minimally invasive transcrestal approach with or without flap, piezosurgery preparation, applying the Schneiderian membrane's hydrodynamic detachment-elevation, injecting albumin-CGF into the sinus, optional bone grafting and implantation, and evaluation for 2 to 6 months postoperatively. Results Eight implants were placed without complications. After 4 to 6 months, cone-beam computed tomography and panoramic radiographs showed total osseointegration and the formation of new bone. In addition, a year of clinical follow-up was performed. There was a positive correlation between implant stability quotient values at all protocol stages. The significance level was 5%. Conclusion Albumin-CGF regenerative protocol promotes new bone formation, reduces postoperative morbidity, and shortens healing time. It also offers a uniform and safe hydraulic membrane lift and bicortical implant fixation, even in cases with a residual bone height below 6 mm.

Введение. Перфорация нижней стенки верхнечелюстной пазухи (ВЧП) с частичным проникновением имплантата в ее полость достаточно часто происходит во время хирургического этапа дентальной имплантации в боковых отделах верхней челюсти. Цель. Установить взаимосвязь между положением верхушки дентального имплантата относительно нижней стенки верхнечелюстной пазухи и степенью выраженности рентгенологических признаков хронического синусита. Материалы и методы. Изучены данные конусно-лучевой компьютерной томографии (КЛКТ) 227 пациентов с диагнозами полной адентии на верхней челюсти или частичной адентии в ее боковых участках, которые наблюдались в частном центре стоматологической имплантации г. Минска в 2020–2021 гг. Основную группу составили 120 пациентов (158 пазух), у которых один или нескольких имплантатов, установленных в боковых участках верхней челюсти, перфорировали дно ВЧП. Группа контроля включала 103 человека (121 пазуха), у которых имплантаты были установлены в боковых участках верхней челюсти на различном удалении от нижней стенки ВЧП без ее повреждения. Результаты. Не обнаружено статистически значимых различий в частоте встречаемости гиперплазии слизистой оболочки ВЧП при наличии или отсутствии имплантата в ее полости, а также при различной глубине пенетрации. Выраженность гиперплазии была выше в основной группе, однако не зависела от глубины, на которую имплантат проникал в полость пазухи. Только у 9,2% пациентов, у которых имплантат/ имплантаты частично проникал/проникали в пазуху, в разные сроки после операции (от нескольких месяцев до нескольких лет) выявлены и рентгенологические признаки, и жалобы, характерные для хронического синусита. У 71 пациента в 102 пазухах (64,6%) перфорация их нижней стенки не сопровождалась клиническими симптомами и рентгенологическими осложнениями в виде утолщения слизистой оболочки. Выводы. Индивидуальные варианты строения остиомеатального комплекса, которые затрудняют естественный мукоцилиарный клиренс, благоприятствуют развитию воспалительного процесса. При отсутствии жалоб гиперплазия слизистой оболочки не может служить основанием для постановки диагноза «хронический верхнечелюстной синусит». Introduction. Perforation of the inferior wall of the maxillary sinus (MS) with the dental implant penetration into the sinus cavity often occurs during surgical installation in the posterior maxilla. Purpose. To establish the relationship between the position of the intraosseous part of the dental implant relative to the inferior wall of the maxillary sinus and severity of radiological signs of chronic sinusitis. Materials and methods. Сone beam computed tomography (CBCT) data from 227 maxillary edentulous patients received medical care at a private dental implant center in Minsk in 2020–2021 were evaluated. The treatment group consisted of 120 patients (158 MS) with dental implants that had radiographic evidence of implant exposure to the maxillary sinus. The control group included 103 patients (121 MS), with implants in the posterior maxilla without perforation of the MS inferior wall. Results. We did not find a statistically significant difference in the incidence of mucosal thickening (MT) of maxillary sinus floor in the presence or absence of an implant penetration into the MS, as well as at different penetrating depths. The severity of MT was greater in the treatment group; however, it did not depend on the depth to which the intraosseous part of the implant penetrated into the sinus cavity. Only in 9.2% of patients with the implants exposed into the MS, both radiological signs and complaints characteristic of chronic sinusitis were revealed at different times after surgical installation (from several months to several years). In 71 patients in 102 sinuses (64.6%), clinical symptoms and mucosal thickening did not accompany perforation of MS inferior wall. Conclusions. Individual variants of the ostiomeatal complex, which may obstruct the mucociliary clearance, are a risk factor for the development of the inflammatory process. In the absence of complaints, maxillary sinus mucosal thickening cannot serve as a basis for making a diagnosis of chronic maxillary sinusitis.
