Treatment of maxillary sinusitis of odontogenic origin

Rezumat. Studiul nostru reprezintă unul retrospectiv efectuat pe un lot de 27 pacienţi la care s-a stabilit diagnoza sinuzita maxilară de origine odontogenă. Pacienţii au fost divizaţi în 3 loturi: lotul I — a fost constituit din 21 de pacienţi cu sinuzita maxilară de origine odontogenă, la care ca tratament am efectuat numai extracţia dintelui cauzal. Lotul II — a fost alcătuit din 4 pacienţi la care s-a aplicat tratamentul funcţional endoscopic, înlăturarea dintelui cauzal și tratamentul medicamentos. Lotul III — din 2 pacienţi, la care s-a efectuat cura radicală și înlăturarea dintelui cauzal. Rezultate: Din 21 de pacienţi din lotul I, la 18 pacienţi numai extracţia dintelui cauzal a fost suficientă pentru a rezolva sinuzita (rata de succes 85%.) și nici o intervenţie adaugătoare asupra sinusului nu a fost necesară. Rata de succes în lotul II și III de pacienţi a constituit 100%. Concluzie: Tratamentul sursei odontogene de infecţie în majoritatea cazurilor va fi suficient pentru tratamentul sinuzitei și cura radicală a sinusului maxilar sau tratamentul funcţional endoscopic nu este obligator în managementul sinuzitei odontogene.Summary. A retrospective study was performed, which included 27 patients with the diagnosis of CMSDO. Extraction of the causative tooth was performed in all patients, the result of the treatment being followed up. Functional endoscopic sinus surgery or radical cure was performed in patients with ineffective treatment. Patients were divided into 3 groups: The first group included 21 patients — only extraction of the odontogenic source, the second group (4 patients) was performed the combination of tooth extraction and FESS, in the third group (2 patients) b– extraction and radical cure of the sinus. Results: In the first group the success rate was 85 %, complete treatment of sinusitis being achieved in 18 patients; in the second and third groups the success rate constituted 100%. Conclusion: Treatment of odontogenic source in most cases is sufficient for sinusitis treatment and FESS or radical cure of the sinus are not mandatory

Effectiveness of causative tooth extraction in maxillary sinusitis of dental origin

Department of Oral and Maxillofacial Surgery and Oral Implantology Arsenie Gutan, Nicolae Testemitanu State University of Medicine and Pharmacy of the Republic of MoldovaIntroduction. Odontogenic maxillary sinusitis (OMS) is an inflammatory disease caused by the spread of dental inflammation into the sinus. The rate of OMS was reported to be 25-40%. A lot of methods of treatment were proposed starting with medicine administration only, till radical sinusotomy. The question is what is the efficacy of the initial treatment, the one that includes the treatment of causal tooth only. Aim of the study. The purpose of this study was to identify the factors of significance that may contribute to the results of the initial treatment of OMS. Materials and methods. Twenty four patients were studied, which were divided in 2 groups, depending on the result of the treatment: effective and non-effective. Efficacy of the treatment was evaluated 3 months after causative tooth treatment with CT scan, which was compared with initial one. First group included 21 patients and the second one 3 persons, that required surgical treatment. Conclusions. 1. Causal tooth treatment of OMS is an effective and miniinvasive method. 2. Maxillary ostium obstruction is an important factor to predict outcome of the treatmen

Lateral sinus floor elevation with simultaneous mucosal cysts management

Introduction. Specialists in the field often face uncertainty in deciding whether to perform sinus lifting surgery in the presence of a mucosal cyst during the pre-implantation preparation of patients with maxillary sinus pathology. While some specialists believe that the sinus lifting operation cannot be performed in the presence of sinus pathology and should be resorted to after a long period of healing, others believe that it can be performed in the presence of sinus pathology or simultaneously with sinus sanitation. As a result, there are more controversies about the treatment tactics, stages, and timing required to achieve the rehabilitation of these patients, demonstrating the significance of the problem at hand. Materials and methods. The study included twenty patients who were referred to the Department of OMF Surgery and Oral Implantology “Arsenie Guţan” and the dental clinic “OmniDent” between 20.06.2016 and 01.01.2019 for implant-prosthetic rehabilitation due to partial edentulism in the upper jaw in the lateral area and the presence of a mucosal cyst in the maxillary sinus. The first group comprised of seven patients in whom the mucosal cyst was completely removed while simultaneously undergoing lateral sinus lifting. The second group consisted of five patients, aged between 18 and 67 years (average 45 years), who underwent marsupialization of the mucosal cyst. The third group comprised of six patients in whom the cyst content was only aspirated, without removal or marsupialization of the cyst. Results. All three methods were found to be effective, although total perforations of the sinus mucosa were recorded in the first two groups, preventing the performance of sinus lifting at that stage. The method of aspirating the cystic content, however, is a simple and low-risk procedure that does not carry the risk of perforating the sinus membrane and provides predictable results. Conclusions. The mucosal cyst does not present a contraindication to sinus lifting but requires additional surgical procedures

Minimally invasive surgical method of oroantral communication closure

Rezumat. Comunicarea oro-sinusală reprezintă o soluţie de continuitate între cavitatea bucală şi sinusul maxilar. Cea mai frecventă cauză a comunicarii orosinusale este extracţia dinţilor laterali la maxilarul superior. Metodele de închidere a comunicării oro-sinusale sunt multiple. În studiul actual au fost comparate metodele tradiţionale prin crearea lambourilor mucoperiostale cu o metoda miniinvazivă prin utilizarea materialului sintetic „Kolapol KP 3LM“. În studiul au fost incluşi 34 pacienţi. Pentru analiza comparativă a metodelor în grupurile studiate am analizat 5 criterii: prezenţa edemului ţesuturilor moi, modificarea laţimii gingiei cheratinizate, modificarea inalţimii vestibulului oral, necesitatea operatiilor repetate, prezenţa sau lipsa recidivei postoperatorii, inalţimea osului subantral si posibilitatea implantării la acest nivel dupa perioada de vindecare. Metoda de plastie cu materialul „Kollapol KP3 LM“ a dovedit eficienţa sa si traumatism minimal.Summary. Oroantral communications are communications between oral cavity and maxillary sinus. The most common cause of oroantral communications is upper first molar extraction. There are a lot of methods of oroantral closure. In this study we compared the method of oro-antral communication closure using vestibular flap versus mini-invasive method using grafting of tooth socket using „Collapol KP3“ (collagen with hydroxyapatite). In study were included 34 patients. To compare 2 groups we used 5 criteria: presence or absence of edema of soft tissues, modification of the width of vestibular keratinized gingiva, modification of the length of the vestibulum of the mouth, the necessity of the repeated operations, the recurrence of OA C, the length of the remaining alveolar bone and possibility of implant placement. The method of OA C closure using osteoconductive material „Collapol KP3“ proved to be effective and minimally traumatic
