RESUMO

The state of the nasal cavity, especially the region of the osteomyomatic complex, plays a significant role in the development of chronic maxillary sinusitis. Odontogenic maxillary sinusitis, as a complication of dental implantological treatment on the upper jaw, is increasingly common. The aim of the study was to increase the effectiveness of prophylaxis and treatment of odontogenic purulent upper jaw sinusitis during reconstructive operations on the alveolar region of the upper jaw. 3 groups of patients were examined: before dental treatment, after dental treatment in the development of odontogenic maxillary sinusitis and 30 patients were selected and examined, who underwent reconstructive surgeries on the alveolar process of the upper jaw and in whom the postoperative period was without complications. The diagnoses of 1st and 2nd group patients required surgical treatment. FESS allows restoring the physiological aeration of maxillary sinuses as naturally as possible, which is important for correct reparative bone regeneration in the alveolar region of maxilla.

RESUMO

OBJECTIVE: The aim of our study was to create a database of the most informative diagnostic criteria for predicting the treatment results for various odontogenic maxillary sinusitis (OMS) forms using automated computer software. PATIENTS AND METHODS: Materials and methods: In order to select and assess the most informative diagnostic criteria for predicting the treatment results for various OMS forms, the total of 9 subject matter experts (SME) were included into the problem commission on the specialty "Dentistry". RESULTS: Results: After calculating the data obtained according to the method of Yana V. Nosova, the working group experts' level of competency was M = 0. 90. This confirmed the group's qualification, which further led to the approval of scoring coefficients, depending on the degree of a particular index importance. The basic and minor parameters in the subjective, objective, introscopic and laboratory data of OMS patients were identified. CONCLUSION: Conclusions: The developed database of diagnostic criteria has formed the basis of an automated computer software for predicting the course and individualizing the patients' treatment in odontogenic maxillary sinusitis.

RESUMO

BACKGROUND: Oral rehabilitation of atrophic maxillae features high complexity, for which there are several therapeutic modalities reported on scientific literature. Zygomatic implant placement is a viable option that features low morbidity and allows immediate prosthetic loading. The purpose of the present study was to determine the methodological quality of systematic reviews that assessed the effectiveness of zygomatic implants placed in atrophic maxillae. MATERIAL AND METHODS: Searches were conducted on Medline via Pubmed, LILACS, Dare Cochrane, Scopus, and Sigle via Open Grey up to June 2019. RESULTS: Seven systematic reviews were eligible for Overview and comprised a total of 2313 patients, 4812 zygomatic implants, and a 96,72% success rate. Common surgical complications, in decreasing order, were: maxillary sinusitis, peri-implant mucositis, prosthetic fracture, and infections. Methodological quality was assessed using the AMSTAR 2 tool, which revealed that six systematic reviews showed critically low methodological quality and one review was assessed as of low methodological quality. CONCLUSIONS: Zygomatic implants seem to be an adequate option for atrophic maxilla rehabilitation, however, new studies with a higher methodological rigor are needed to provide more reliable results to professionals and patients undergoing this modality of oral rehabilitation.

RESUMO

Pathological ventilation of the maxillary sinus (MS) is one of the risk factors for the formation of chronic maxillary sinusitis. PURPOSE OF STUDY: Is to evaluate the effectiveness of the method of restoring the medial wall of the MS with an autograft - a quadrangular cartilage of the nasal septum using the butterfly technique (Patent Application No. 2018140468, priority of 11/19/2018). MATERIAL AND METHODS: The study included patients who underwent septoplasty, endoscopic surgery on the MS with plasty of the medial wall of the MS (1st, main group, n=136), as well as patients who underwent surgery according to Caldwell-Luc with the formation of persistent nasoantral anastomosis in the lower nasal passage (2nd, control group, n=56). The criteria for the inclusion of patients in the study were as follows: the presence of MS fungal body; inverted papilloma with lesions of the MS; cysts and/or a foreign body of the MS with localization in the alveolar bay without involving the natural anastomosis in the pathological process; concomitant 3rd or 4th, or 5th or 6th types of curvature of the nasal septum according to R. Mladina (1987). An objective assessment of the condition of the patients was carried out using the SNOT-22 clinical questionnaire, and for analysis the state of aerodynamics of the nasal cavity and MS in patients of various groups after surgical treatment used the method of computational aerodynamics. RESULTS: In patients with nasoantral ostium in the lower nasal meatus, the pathological maxillary sinus aeration one was observed. It is recommended to close the nasoantral ostium to prevent violations of the aerodynamics of the nasal cavity and the maxillary sinus during surgery through the lower nasal meatus. CONCLUSION: Our proposed method for closing a defect in the lower nasal passage is effective. The autograft is well established, contributes to the speedy restoration of normal sinus aerodynamics.

RESUMO

OBJECTIVE: This study was performed to evaluate the incidence, timing, and factors contributing to recurrent maxillary sinusitis due to middle meatal antrostomy (MMA) site stenosis after endoscopic sinus surgery (ESS). METHODS: The medical records and endoscopic photographs of 288 patients with chronic rhinosinusitis who underwent ESS were evaluated. Patients visited the clinic with similar schedule after ESS; recurrent maxillary sinusitis due to MMA site stenosis was investigated, including in terms of the incidence and timing. The preoperative computed tomography (CT) scans, intraoperative findings, and possible factors contributing to MMA site stenosis were examined. RESULTS: Recurrent maxillary sinusitis due to MMA site stenosis occurred in 10 patients. Most had unilateral sinusitis and stenosis was observed within 6 months postoperatively. All patients had severe inflammation, pus retention, and thick mucosal hypertrophy in the maxillary sinus on preoperative CT; intraoperative findings confirmed these conditions. In most patients, extensive trimming of the hypertrophied mucosa was performed intraoperatively through canine fossa trephination. CONCLUSIONS: MMA site stenosis is a rare condition after ESS. We hypothesized that rapid shrinkage and fibrosis of the sinus mucosa after extensive trimming thereof may be the main causes of stenosis. Residual mucosal inflammation, granulation formation, and persistent sinus crust and debris may also be contributing factors. Therefore, conservative trimming, meticulous dressing, and removal of sinus crust and granulation tissue near the MMA site should be performed in patients with MMA site stenosis.

RESUMO

AIM: The aim of the present study was to present a case of maxillary aspergillosis with unusual clinical presentation and imaging findings. BACKGROUND: The range of lesions and conditions that affect the maxillary sinus is wide and vast. This necessitates a dynamic multidisciplinary approach for proper diagnosis and effective management. CASE DESCRIPTION: We present an unusual case of maxillary aspergillosis that mimicked apical periodontitis and was most consistent with lymphoma from the diagnostic imaging perspective. Histopathology, however, established the correct diagnosis; appropriate management commenced promptly. CONCLUSION: It is imperative that maxillary aspergillosis be diagnosed and managed properly and promptly to improve prognosis. Advanced imaging is required, but it plays an adjunct role to histopathology. Long-term follow-up is also necessary to ensure complete resolution of the infection. CLINICAL SIGNIFICANCE: Correlating clinical and imaging findings is a crucial step and any inconsistencies should be resolved promptly so as not to delay adequate management. Histopathology often serves to dispute any inconsistencies and allows the establishment of a proper diagnosis.

RESUMO

OBJECTIVE: This study aimed to propose appropriate management for odontogenic chronic rhinosinusitis. METHOD: Thirty-one adult patients with odontogenic chronic rhinosinusitis undergoing maxillary extraction were retrospectively analysed. Patients with (n = 21) and without (n = 10) oroantral fistula on computed tomography were classified. Functional endoscopic sinus surgery was performed when sinusitis did not improve after extraction. The critical indicators for surgical requirement in the management of odontogenic chronic rhinosinusitis were analysed. RESULTS: Sinusitis significantly improved after extraction in both groups. Patients without oroantral fistula had significantly more severe remnant sinusitis than those with oroantral fistula after extraction on computed tomography (p = 0.0037). The requirement for functional endoscopic sinus surgery was statistically significant for patients without orofacial fistula over those with orofacial fistula (p < 0.0001). The surgical improvement ratio was 93 per cent. CONCLUSION: The absence of oroantral fistula and severe sinusitis can be critical indicators for the requirement of functional endoscopic sinus surgery after extraction in the management of odontogenic chronic rhinosinusitis.

RESUMO

This study was performed to test a protocol for trans-implant treatment of chronic recurrent maxillary sinusitis (CRS), via implants with an internal removable sealing screw. The appropriate indications for treatment, optimal number of treatment sessions, and general schedule of treatment and follow-up were assessed. This was a retrospective study of 31 patients with CRS who were managed with trans-implant lavage. Of these patients, 28 (referred for a sinus elevation procedure) underwent a simultaneous implantation procedure and treatment of the sinusitis. Three patients received treatment for sinusitis via an already existing implant. The suggested sinusitis treatment protocol includes the drainage of pus through the punctured sinus floor and three sessions of antral irrigation/lavage, four cone beam computed tomography scans, and four transnasal endoscopic observations. The suggested combined protocol includes the simultaneous evaluation of the implant status and the sinusitis treatment results on days 30 and 60 after surgery. Of the 31 patients, 28 (90%) had complete relief of most of their symptoms (nasal obstruction/discharge, anosmia/hyposmia) up to day 30 postoperative. Follow-up nasal endoscopy demonstrated no evidence of active sinus disease. Twenty-seven implants were well-osseointegrated and were still in use for prosthetic purposes. In one case, the implantation failed because of poor bone quality. For the remaining 30 cases, both clinical and radiological results showed stability of the implants and no CRS recurrence during the whole follow-up period. The dental implant with an internal central port and an integral sealing screw may be used for drainage, irrigation, observation, and further treatment of the maxillary sinus in cases of CRS.

RESUMO

BACKGROUND: A study is made of the association between maxillary sinus pathology and odontogenic lesions in patients evaluated with cone beam computed tomography. MATERIAL AND METHODS: A literature search was made in five databases and OpenGrey. Methodological assessment was carried out using the Newcastle-Ottawa tool for observational studies. The random-effects model was used for the meta-analysis. RESULTS: Twenty-one studies were included in the qualitative review and 6 in the meta-analysis. Most presented moderate or low risk of bias. The periodontal disease showed to be associated with the thickening of the sinus membrane (TSM). Mucous retention cysts and opacities were reported in few studies. The presence of periapical lesions (PALs) was significantly associated to TSM (OR=2.43 (95%CI:1.71-3.46); I2=34.5%) and to odontogenic maxillary sinusitis (OMS) (OR=1.77 (95%CI: 1.20-2.61); I2=35.5%). CONCLUSIONS: The presence of PALs increases the probability of TSM and OMS up to 2.4-fold and 1.7-fold respectively. The risk differences suggests that about 58 and 37 of out every 100 maxillary sinuses having antral teeth with PALs are associated with an increased risk TSM and OMS respectively. The meta-evidence obtained in this study was of moderate certainty, and although the magnitude of the observed associations may vary, their direction in favor sinus disorders appearance, would not change as a result.

RESUMO

In 2017-2018, the authors examined and operated on 35 patients aged 20 to 39 years (19 women, 16 men) with cystic maxillary sinusitis. The study included patients who were diagnosed with retention cyst of the maxillary sinus, located on the lower walls of the maxillary sinus and dealing with no more than 2/3 of the maxillary sinus volume, according to CT of the paranasal sinuses. The operation was performed using the following method: two punctures of the sinus were performed simultaneously in a typical place in the lower nasal passage - using a Kulikovsky needle and using a 2.8 mm trocar. The fiber of the Ho-laser was inserted into the Kulikovsky needle, and an endoscope was inserted into the trocar in parallel with the 0, 30 or 45°. Then, under the control of the endoscope, the fiber was inserted into the cyst and given a series of impulses before its 'explosion'. The parameters Ho:YAG-radiation had the following values: power - 14.4 W, pulse energy - 1.2 Jol, pulse frequency - 12.0 Hz. All patients were discharged from the hospital on the 2nd day. In the long-term period (up to 14 months), according to the endoscopic examination, an objective examination and CT of the paranasal sinuses showed no recurrence of the cyst in any patient, no pathological changes were recorded in the area of the lower nasal passage.

RESUMO

Odontogenic infection is a possible cause of maxillary sinusitis. In this case series, the authors evaluated patients who presented with maxillary sinusitis symptoms before and after dental treatment. Intraoral periapical radiographs and cone-beam computed tomography (CBCT) scans were performed on three patients whose maxillary sinusitis symptoms included pain, sinus congestion, respiratory complaints, and what appeared on CBCT to be sinus mucosal thickening. In the first of the three cases, root canal treatment was done. The second case entailed root canal treatment and extraction of the second molar, and in the third case endodontic retreatment was performed. Each patient had a pretreatment CBCT taken and one again at a 4- to 12-month post-treatment follow-up visit. All three patients who presented with moderate-severe sinusitis had reduced symptoms after odontogenic treatment. Post-treatment CBCT confirmed near to complete resolution of sinus mucosal thickening in all patients. These cases show that maxillary sinusitis of odontogenic origin can respond favorably to dental treatment. This case series emphasizes the importance of a medical and dental collaboration when determining treatment for patients who present with maxillary sinusitis. Additionally, the use of CBCT was essential for evaluating the maxillary sinus and its associated odontogenic conditions.

RESUMO

Unilateral recurrent maxillary sinusitis is a common sinunasal pathology, mostly related to the ostiomeatal complex dysfunction. Although sinusitis can potentially spread to the adjacent structures, orbital cellulitis remains an exceptionally rare sequela.The authors report the unusual case of a patient who presented with recurrent maxillary sinusitis complicated by cyclic episodes of periorbital cellulitis related to ostiomeatal complex obstruction from herniated periorbital fat through an unnoticed medial orbital wall fracture. To the best of our knowledge, no other similar case has previously been reported. The possible explanation for such an unusual association is discussed.

RESUMO

OBJECTIVES: To report an unusual complication of pediatric acute maxillary sinusitis: premaxillary abscess. To describe clinical, radiological and biological presentation, treatment strategy and progression. MATERIAL AND METHODS: A retrospective study included all pediatric patients treated for premaxillary abscess complicating acute maxillary sinusitis in two ENT reference centers between 1999 and 2017. Disease history, clinical presentation, biological and radiological findings, treatment modalities and progression were studied. RESULTS: Ten patients were included, with a mean age of 10±4.2 years. All presented with fever, rhinorrhea and premaxillary edema. Contrast-enhanced CT scan systematically found complete opacity of the maxillary sinus, without bone lysis, and extensive effusion along the intersinonasal wall up to the premaxillary region, extending in 3 cases back toward the parapharyngeal space. Bacteriology isolated Streptococcus anginosus most frequently (n=4; 40%). Treatment comprised intravenous wide-spectrum antibiotics, with surgical drainage of the abscess if>10mm (n=9; 90%). Seven of these 9 patients (78%) had recurrent abscess requiring surgical revision and 3 (33%) required a third drainage. All patients were cured without sequelae at 1 month. CONCLUSION: In case of acute maxillary sinusitis with premaxillary edema, premaxillary abscess should be suspected. The high recurrence rate argues for maximalist surgery associated to close clinical monitoring with radiological examination.

RESUMO

We present a rare and unusual case of a 16-year-old girl, with no significant medical history, presenting with right nasal obstruction and suspected sinusitis with occasional epistaxis and haemoptysis. On examination, she had a mass lesion in the right nasal cavity, with no evidence of other pathology on assessment of the ears, nose, throat or head and neck. A CT scan revealed an opacified right maxillary sinus with polypoidal mucosa, extending and passing through the accessory ostium into the right nasal cavity. Examination under anaesthesia with functional endoscopic sinus surgery and excision of the lesion was subsequently undertaken. Histological analysis confirmed the mass lesion as a haemangioma. This case report is the first to present a maxillary haemangioma presenting as nasal obstruction with intermittent sinusitis symptoms in a child. The authors discuss the incidence, presentation and management of maxillary haemangiomas in the paediatric population.

RESUMO

Sinus elevation is a common procedure to increase bone volume in the atrophic maxilla to allow placement of dental implants. Autogenous bone is the gold standard but is limited in quantity and causes morbidity at the donor site. ß-TCP is a synthetic biomaterial commonly used in that purpose. It appears to induce a poor inflammatory response. This study aimed to evaluate the degree of edema of the sinus mucosa after sinus lift surgery according to the type of biomaterial. Forty sinuses (20 patients) were included retrospectively and divided into 2 groups according to the biomaterial that was used: synthetic biomaterial (BTCP group), natural bone (BONE group). A control group (CTRL group) was constituted by the non-grafted maxillary sinuses. Twelve measurements per sinus were realized on pre- and post-operative computed tomography and averaged to provide the sinus membrane thickness value (SM.Th). SM.Th was thicker post-operatively in the BTCP and BONE groups in comparison with the CTRL group and in comparison with pre-operative measurements. No difference was found post operatively between the BTCP and BONE groups. We found that a synthetic biomaterial (ß-TCP) induced the same degree of edema, and thus of inflammation, as natural bone. It constitutes therefore an interesting alternative to autogenous bone for maxillary sinus lifts.

RESUMO

OBJECTIVE: High-throughput DNA sequencing of the paranasal sinus microbiome has potential in the diagnosis and treatment of sinusitis. The objective of this study is to evaluate the use of high-throughput DNA sequencing to diagnose sinusitis of odontogenic origin. STUDY DESIGN: Case series with chart review. SETTING: Single tertiary care academic medical center. SUBJECTS AND METHODS: A chart review was performed of DNA sequencing results from the sinus aspirates obtained under endoscopic visualization in 142 patients with sinusitis. The identification of any potentially pathogenic bacteria associated with oral flora in a sample was classified as a positive result for sinusitis of odontogenic etiology. The sensitivity, specificity, and predictive values of using high-throughput DNA sequencing to diagnose sinusitis of odontogenic etiology were determined, with the patient's computed tomography sinus scan as the reference standard. On computed tomography scans, an odontogenic source was determined by the presence of a periapical lucency perforating the schneiderian membrane. RESULTS: Seven of the 142 patients enrolled in this study had an odontogenic source based on computed tomography scans. Relative to this reference standard, high-throughput DNA sequencing produced a sensitivity of 85.7% (95% CI, 42.1%-99.6%), a specificity of 81.5% (95% CI, 73.9%-87.6%), a positive predictive value of 19.4% (95% CI, 13.1%-27.7%), and a negative predictive value of 99.1% (95% CI, 94.7%-99.9%). CONCLUSION: This study supports the use of high-throughput DNA sequencing in supplementing other methods of investigation for identifying an odontogenic etiology of sinusitis.
