Sinusitis odontogénica, fístula oroantral y su reparación quirúrgica mediante colgajo de bolsa de Bichat: revisión de la literatura

Odontogenic sinusitis accounts for 10-12% of maxillary sinusitis. It occurs due to an interruption of the mucoperiosteum in response to a series of conditions, most frequently the extraction of a superior tooth. Its treatment has two bases: treating the infection and managing the oroantral fistula that perpetuates the infection. Communications smaller than 5mm can resolve spontaneously; bigger ones must be closed by a flap. Bichat's fat pad flap was first used in 1977 to close an oroantral fistula. It is a pedicled flap that has been shown to be successful, with advantages that make it the best option in oroantral fistula treatment. Its location allows easy access, minimum dissection, great versatility, good mobility, good blood supply, low rate of complications, no morbidity in the donor site, low risk of infection, shortened surgical time and fast cover by epithelium, and it leaves no visible scar, amongst other benefits. That is why we encourage the use of this technique and choose it as the best option for management of our patients.

Odontogenic and rhinogenic chronic sinusitis: a modern microbiological comparison.

Odontogenic sinusitis and sinonasal complications of dental disease or treatment (SCDDT) play a relevant, often underappreciated role in paranasal sinus infections. Treating SCDDT patients requires tailored medical and surgical approaches in order to achieve acceptable success rates. These approaches differ from common rhinogenic sinusitis treatment protocols mostly because of the different etiopathogenesis. Our study comprehensively evaluated microbiology and antibiotic resistance in SCDDT patients and compared findings with a control group of patients affected by rhinogenic sinusitis. We performed microbiological sampling during surgery on 28 patients with SCDDT and 16 patients with chronic rhinosinusitis with nasal polyps (CRSwNP). Colonies were isolated, Gram-stained, and the species identified using classic biochemical methods. These results were confirmed by DNA pyrosequencing, and then the resistance profile of each SCDDT isolate to various antibiotics was tested. Microbial growth was observed in all SCDDT patients, whereas samples from 60% of patients in the control group failed to yield any bacterial growth (p < 0.001). Anaerobes grew in 14% of SCDDT patients as compared to 7% of CRSwNP patients (p = 0.42). Of the isolates from SCDDT patients, 70% were susceptible to amoxicillin/clavulanate, whereas all isolates were susceptible to levofloxacin, teicoplanin, and vancomycin. Of the staphylococci identified, 80% were capable of producing beta-lactamase. Given the extent of microbiological contamination within the maxillary sinus of SCDDT patients, these infections should be regarded as a different class of conditions from rhinogenic sinusitis. Our findings support the need for different approaches in the treatment of SCDDT patients.

Etiology and clinical characteristics of symptomatic unilateral maxillary sinusitis: A review of 174 cases.

The purpose of the study was to analyze the causative pathology associated with symptomatic unilateral maxillary sinusitis requiring surgical treatment. A retrospective review of all patients that have been treated surgically for unilateral symptomatic maxillary sinusitis between 2006 and 2013 at a single institution was performed. Demographic, anamnesis, clinical, radiological, microbiological and histological data were gathered and analyzed. The patients were allocated into groups depending on the underlying cause of the disease. Descriptive and inferential statistics were computed (level of significance: p ≤ 0.05). The study sample was composed of 174 patients (72 female; 102 male) with a mean age of 52.7 years (SD 16.9). Most cases (130; 75%) were triggered by odontogenic pathology following dentoalveolar surgical interventions (83/130 patients; 64%). Other etiological factors for odontogenic unilateral sinusitis were periapical (23/130 cases; 18%) and periodontal pathology (13/130 cases; 10%). Rhinogenic factors for sinusitis were detected in 13 patients (7.5%) and dental implant-associated unilateral maxillary sinusitis was diagnosed in nine patients (5.2%). Four patients (2.3%) had undergone previous sinus augmentation surgery. A leading cause for the sinus infection could not be identified in 18 patients (10%) who all had a history of midfacial surgery. Medication-related osteonecrosis of the jaw (8) and squamous cell carcinoma (2) were incidental findings. There were no differences in the clinical appearance of the disease with respect to its etiology. Odontogenic causes for maxillary sinusitis must be considered especially in unilateral cases. Maxillary dental implants may induce symptomatic unilateral maxillary sinusitis.

Odontogenic sinusitis: a case series studying diagnosis and management.

Odontogenic sinusitis is a well-recognized, but understudied form of sinusitis. Odontogenic sinusitis requires unique diagnostic criteria and a treatment regimen that differs from non-odontogenic sinusitis. The purpose of this article is to present a case series of patients with odontogenic sinusitis in order to clarify key disease characteristics and management techniques. Retrospective case series of 55 patients with odontogenic sinusitis. Each patient underwent chart and imaging review to analyze demographic factors, diagnostic criteria, clinical course, and management. Fifty-five patients were identified retrospectively. Forty-four were diagnosed at initial visit. Twenty-eight (64%) of these patients were diagnosed by computed tomography (CT) scan showing dental pathology, 11 (25%) by known temporal relationship to a dental procedure, and 5 (11%) by presentation with oral-antral fistula. Only 65% of radiology reports for all patients mentioned dental pathology. Overall, 21 (38%) patients had disease resolution. Of these, 7 (33%) resolved with endoscopic sinus surgery (ESS) alone, 7 (33%) resolved with concurrent ESS and dental surgery, 2 (10%) resolved with dental surgery alone, 2 (10%) resolved with ESS after failing dental surgery, 2 (10%) resolved with medical management alone, and 1 (5%) resolved with medical management after failing dental surgery. Forty-six (84%) patients had unilateral odontogenic sinusitis. The Lund-Mackay score for all patients was (mean ± standard deviation [SD]) 4.0 ± 3.2. Odontogenic sinusitis is often misdiagnosed. Radiology reports commonly do not mention dental pathology. Management of odontogenic sinusitis needs to be tailored to each individual patient and involves varying combinations of medical management, dental surgery, and ESS.

Clinical features and treatment outcomes of dental implant-related paranasal sinusitis: A 2-year prospective observational study.

As dental implant-related paranasal sinusitis has different pathophysiology and clinical features from primarily rhinogenic paranasal sinusitis, the standard treatment protocol for dental implant-related paranasal sinusitis has not yet been established. The aim of this study was to analyze the clinical characteristics and treatment results of dental implant-related paranasal sinusitis. We conducted a prospective single-center study of 19 patients who were treated for odontogenic sinusitis developing in relation to dental implant from September 2008 through May 2012. The age of the patients ranged from 33 to 78years, with the mean age of 54.5years. Foul odor and postnasal dripping were the two most common complaints. All patients underwent nasal endoscopic examination and paranasal sinus CT before treatment, and initial conservative treatment for 1week. Patients unresponsive to medical treatment underwent endoscopic sinus surgery (ESS). All patients were classified into the conservative and surgical groups for analysis and followed up for 2years after initial diagnosis. Four patients (21%) were successfully treated conservatively, while 15 patients (79%) underwent surgical treatment. One of these 15 patients required revision surgery. After 2years, all patients were successfully treated, so there were no more clinical signs of recurrent sinusitis in any patients. The survival rate of implants was 100%. Compared to those of the conservative group, symptom duration, the Lund-MacKay CT score, status of the ostiomeatal unit (OMU), and the condition of the maxillary sinus floor were significantly more severe in the surgical group. In our study, the majority of patients who once developed paranasal sinusitis associated with dental implants required surgical treatment. Findings of paranasal sinus CT may be important in determining treatment option.

Association between odontogenic infections and unilateral sinus opacification.

Consideration of the causes of unilateral paranasal sinusitis, which frequently occurs in routine medical care and is often associated with odontogenic infection. Retrospective data analysis. A review of the charts of all 190 patients treated for unilateral paranasal sinusitis at our department between 2005 and 2012 was carried out. All patients were diagnosed based on clinical signs, symptoms, and imaging findings, including computed tomography (CT), orthopantomography (OP), and other modalities. Patients were classified in three groups: patients with odontogenic infection involvement (Group A); patients without odontogenic infection involvement (Group B); and patients with inconclusive odontogenic infection involvement (Group C). The most common cause of unilateral paranasal sinusitis was odontogenic infection, as seen in 138 cases (72.6%), followed by chronic inflammation in 43 cases (22.6%). Among patients diagnosed with odontogenic infection, one patient was also diagnosed with coexistent polyps and mycosis. Based on CT, OP, EPT, and oral examination, final distribution was 138 patients (72.6%) in Group A, 32 (16.8%) in Group B, and 20 (10.5%) in Group C. Odontogenic infection involvement was implicated in approximately 70% cases of unilateral paranasal sinusitis. Odontogenic maxillary sinusitis can be difficult to diagnose, and consideration of imaging performed under various conditions is recommended. In order to determine the most appropriate treatment for unilateral paranasal sinusitis, whether such treatment will be surgery, dental treatment, conservative therapy, or other treatments, collaboration between concerned doctors is essential.

Uncinate process deviation in patients with odontogenic sinusitis: a computed tomographic evaluation

The uncinate process of the ethmoidis is one of the anatomic boundaries of osti- omeatal complex. Its relationship with the maxillary sinus ostium makes it the key landmark for endoscopic sinus surgery. Many authors denied a direct role of the uncinate process in the development of sinonasal infections (1). Nevertheless, chronic sinonasal diseases are often accompanied by an uncinate process antero-medialization, most notably in presence of an odontogenic etiology. This study aimed to retrospectively analyze uncinate process anatomy on computed tomographic (CT) scans, defining the association between uncinate process inclination and sinonasal health status. Sinonasal CT examinations of 46 individuals were reviewed, comparing patients without clinical and radiographic signs of sinonasal diseases (Group I), and patients diagnosed with odontogenic sinusitis according to the criteria proposed by Felisati et al. (2)(Group II). Uncinate process inclination was calculated by Radiant Dicom Viewer software, as the angle between the straight line connecting the antero- superior and the postero-inferior part of uncinate process, and the axis of symmetry, passing through sphenoidal rostrum and perpendicular to bizygomatic line. For each patient three axial scans (the most cranial, median, the most caudal), in which uncinate process was clearly detectable, were selected and a mean value was computed. Descriptive statistics of uncinate process inclination were calculated separately in the two groups. In Group I the mean angle was13.18° ± 10.33°with confidence limits (CL) (99%) between 6.21° and 20.15°,in Group II the mean angle was 29.89°±9.56° with CL between 24.44° and 35.34°. From these preliminary results, a marked medial devia tion of uncinate process was identified in odontogenic sinusitis compared to healthy sites. Additional assessments are required to confirm the role of this anatomical varia- tion in the pathogenesis of odontogenic sinusitis.

Modern clinical and radiological approach to diagnostics of odontogenic sinusitis

Inflammatory diseases of the maxillary sinuses affect up to 70% of the adult population. Odontogenic maxillary sinusitis represents 13-86% of the inflammatory processes of maxillofacial area, with the incidence range being explained rather by varying diagnosis criteria than the true incidence difference of odontogenic lesions. The aim of the study was to summarize the clinical and radiological characteristics of odontogenic sinusitis according to patients records in the Department of Maxillofacial Surgery of Omsk Clinical Hospital No11 and the oral surgery department of BUZ GKSP No1 in 2009-2014. A total of 948 records of patient (aged 17 to 68 years) with maxillary sinusitis were identified. X-ray examinations were performed by CT PISASSO TRIO ("KoYo", South Korea) and MSCT Brillians 6 and Brillians 64 ((Philips HealthCare), Netherlands). Images were obtained in axial projection with slice thickness of 0.2-0.6 mm with multiplanar reconstructions (MPR) in a variety of direct and oblique projections. Altogether 664 patients were diagnosed with foreign bodies in the maxillary sinuses (filling material in 569 cases, roots or root fragments? implants, rubber drains, fragments of endodontic instruments in 95 cases). In 284 persons odontogenic cysts were found. Almost every fifth case was complicated by mycotic infection. Analysis of the results showed that only a multidisciplinary approach including dentists, maxillofacial surgeons, otolaryngologists and radiologists, as well as dental volumetric tomography or multislice CT can ensure the correct clinical and radiological approaches to determine the tactics of treatment in patients with sinusitis, reduce the incidence of relapses and chronic inflammatory processes in the maxillary sinuses.

The experience with the application of a lyophilized xenodermograft for the treatment of the patients suffering from frequently recurring inflammation of the maxillary sinus in combination with alveolar fistula

The objective of the present study was to summarize the data of the special literature concerning methods of the surgical treatment of odontogenic maxillary sinusitis complicated by the alveolar fistula with the purpose of using them for the improvement of the effectiveness of the treatment of the patients presenting with this pathology. The study group was comprised of 39 patients with odontogenic diseases of paranasal sinuses and alveolar fistulas. The alveolar fistulas were closed in 20 patients by means of plastic surgery with the use of a lyophilized xenodermograft prepared from the pig's skin. Not a single case of relapse of the inflammatory process in the maxillary sinuseswas documented within one year after the treatment by means of the closure of the alveolar fistula using the lyophilizedxenodermografts.

The modern strategy for the treatment of the patients presenting with odontogenic maxillary sinusitis and the oroantral fistula

The objective of the present study was the comparative analysis of various methods for the plastic correction of the oroantral fistula with the use of the mucosal flap and the osteoplastic materials based on the data from the literature and on-line publkations. The characteristics of an ideal material for the plastic correction ot the oroantral fistula and the conditions for carrying out this surgery are discussed.

Bilateral Diplopia and Abducent Nerve Palsy Secondary to Odontogenic Sinusitis : An Unusual Presentation

We present a patient with double vision, photophobia, headache and gait disturbance secondary to odontogenic sinusitis. The initial diagnosis was meningitis; the patient had bilateral diplopia, severe unilateral facial pain, nasal blockage, photophobia, headache and gait disturbance. The Patient underwent a septic screening and CT scan of the nose and paranasal sinuses which confirmed unilateral pan-sinusitis. MRI revealed enhancement of bilateral abducent nerves secondary to irritation of the meninges by the opacified sphenoid sinus.

Odontogenic maxillary sinus pathology

But de la presentation There is a close anatomical relationship between the root apices of the molar and premolar teeth and the maxillary sinus floor. It is therefore possible that odontogenic diseases, dental treatment and the position of a dental implant affect the maxillary sinus. The authors exposed 3 case reports and a literature review of maxillary sinus pathology with an odontogenic origin. Materiel et methodes Three clinical cases of unilateral odontogenic sinusitis are presented. The presenting symptoms, diagnostic procedures, treatment and follow-up of patients are exposed and discussed. A literature review is conducted. Resultats The first case is an extensive radicular cyst, which caused important unilateral maxillary swelling; the treatment was a combination of endoscopic sinus surgery and a Caldwell-Luc operation. The second case reports an oroantral fistula of the alveolo-sinusal type after an upper premolar extraction; the patient remained with signs and symptoms of odontogenic sinusitis after medical treatment and consequently a surgical closure of the oroantral fistula was performed. The third case is a displaced dental implant in the maxillary sinus that was removed by endoscopic sinus surgery, thus avoiding a more aggressive external procedure. Conclusion Due to the relations and the anatomical structure of the upper jaw, a careful differential diagnosis of pathology of the maxillary sinus is needed. The dental origin of the maxillary sinus pathology remains overlooked, which leads to a delay in diagnosis and proper treatment. A correct diagnosis is based on a carefully taken clinical history, which should include the presence of dental pathology and/or instrumentation and reference to unilateral symptoms. The majority of the cases require endodontic treatment and medical treatment for sinusitis. In specific cases, surgery becomes the necessary treatment path for the resolution of dental pathology and inflammatory processes of the maxillary sinus.

Redefining boundaries in odontogenic sinusitis: a retrospective evaluation of extramaxillary involvement in 315 patients.

Odontogenic sinusitis and "sinonasal complications of dental disease or dental treatment" (SCDDT) have been assumed to be limited to the maxillary sinus. Nevertheless, many patients also show more extensive sinonasal involvement and, occasionally, also have associated bilateral disease. We evaluated the incidence of extramaxillary extension over an 11-year period in our clinic. We retrospectively evaluated 315 surgically treated SCDDT patients. Sinonasal involvement was assessed with presurgical imaging and confirmed with intraoperative findings. Patients were subsequently categorized into 3 groups, based on the sinonasal extension. In 40.3% of patients the sinonasal condition was limited to the maxillary sinus. Forty-one percent of patients had unilateral extramaxillary involvement, and in 18.7% of patients, we found bilateral involvement. Complete presurgery evaluation with endoscopy and a computed tomography (CT) scan in SCDDT patients is essential. SCDDT patients not responding to medical and dental treatment should be addressed with a planned approach targeting the extramaxillary extension, which may necessitate a combined oral and endonasal approach. It is unclear whether disease in the maxillary sinus contralateral to the primary maxillary sinus demonstrating odontogenic-induced disease is incidental, associated, or represents a subclinical odontogenic infection.

Extended inferior meatal maxillary antrostomy through inferior turbinate reversing approach for maxillary lesions

To explore the feasibility of the extended inferior meatal maxillary antrostomy through inferior turbinate reversing approach. Eight patients underwent extended inferior meatal maxillary antrostomy through inferior turbinate reversing approach for maxillary sinus lesions. The indications, surgical management and outcomes of the surgery were presented. There were 2 cases of maxillary dentigerous cyst with oroantral fistula, 2 cases of antrochoanal polyp, 2 cases of maxillary sinus inverted papillomas, 1 case of odontogenic maxillary sinusitis with oroantral fistula, and 1 case of maxillary sinus mucocele. All patients underwent extended inferior meatal maxillary antrostomy through inferior turbinate reversing approach without intraoperative complication, with good access to the lesions. Complete resection could be achieved through this approach, no postoperative complications occurred except one patient had a delayed wound healing of inferior turbinate, all patients were free of recurrence with the average postoperative follow-up of 7.8 months (range 4-12 months). The extended inferior meatal maxillary antrostomy through inferior turbinate reversing approach is recommended for some maxillary pathology owing to its good access to the lesions and complete resection.

Rhinosinusitis in oral medicine and dentistry.

Rhinosinusitis is a very common condition which is normally readily recognizable. Given the intimate anatomic relationship between the antrum and the posterior maxillary teeth, maxillary sinusitis can present as odontalgia. Distinguishing between odontogenic orofacial pain and pain associated with maxillary sinusitis is important to prevent unnecessary dental intervention and to direct patients to medical colleagues. Conversely, odontogenic infection can spread to involve the antrum, termed odontogenic sinusitis, or maxillary sinusitis of dental origin. Odontogenic sinusitis accounts for about 10-40% of all cases of sinusitis, and usually requires combined dental and medical treatment. Maxillary sinusitis can also be a complication of exodontia, resulting from tuberosity fractures, displaced teeth or root fragments and the creation of oroantral communications and fistulae. Dental implants and endodontic materials can also impinge on the maxillary sinus, and are rare causes of sinusitis. Often it is stated that rhinosinusitis may contribute to a halitosis complaint, and widely used diagnostic protocols for rhinosinusitis sometimes list halitosis as a minor criterion. However, gold standards in halitotosis research such as organoleptic assessment or gas chromatography have not been used to validate a correlation between objective (genuine) halitosis and sinusitis. The pathophysiology of this mechanism is unclear, and the relative importance of this alongside other causes of extraoral halitosis is debated.

Aperture width of the osteomeatal complex as a predictor of successful treatment of odontogenic maxillary sinusitis

Odontogenic maxillary sinusitis (OMS) is an inflammatory disease caused by the spread of dental inflammation into the sinus. The long-term administration of antibiotic medicine and/or treatment of the causative tooth are the usual initial treatments. These initial treatments are not always effective, and the reason is not well understood. The purpose of this study was to identify factors of significance that may contribute to the results of the initial treatment of OMS. Thirty-nine patients were studied, divided into two groups according to the results of initial treatment: effective or non-effective. The effective group comprised 20 patients who were cured by initial treatment. The non-effective group comprised 19 patients who required an additional operation. The duration of symptoms, spread into the other sinuses, aperture width of the osteomeatal complex (OMC) on the side of the maxillary sinus, and anatomical variations in the sinuses were compared between the groups. The only significant difference found was in the aperture width of the OMC, which was significantly narrower in the non-effective group than in the effective group. The aperture width of the OMC may be a significant predictor of the effectiveness of initial treatment of OMS.
