RESUMO

The article presents a clinical example of the course of posttraumatic acute purulent sinusitis with reactive soft tissue phenomena due to the previous injury of the orbit by a foreign body, the introduction of the latter into orbit and the maxillary sinus result in a fracture of the lower wall of the orbit. A feature of the injury is the penetration of a foreign body through the conjunctiva of the lower eyelid and lower conjunctival fornix, without damaging the skin. This case is professionally interesting for both young doctors and experienced specialists in otolaryngology, ophthalmology, maxillofacial surgery and neurosurgery. Experts, analyzing this clinical example, will be able to correctly diagnose, effectively eliminate the inflammatory process in the maxillary sinus.

RESUMO

OBJECTIVE: The aim of the study was to study the structure of odontogenic sinusitis and identify iatrogenic etiological factors. MATERIAL AND METHODS: A retrospective analysis of the case histories of patients operated from 2015 to 2019 with a diagnosis of «Sinusitis¼ in the Clinical City Emergency Hospital in Tashkent, Republic of Uzbekistan in the department of emergency maxillofacial surgery was carried out. The total number of patients was 333 people: 105 (31.5%) men and 228 (68.5%), the average age of patients was 39.4 years. RESULTS: When analyzing the reasons for the development of sinusitis, in 73% of the total number of operated patients, there was an associated lesion of the teeth. When detailing the sources of odontogenic infection, it was determined that periapical foci of inflammation (granulomatous, granulating periodontitis, cystogranulomas) accounted for 26%, foreign bodies (teeth, roots of teeth, filling materials removed into the maxillary sinus during endodontic treatment) 31%, fistulous passages after removal teeth and attempts to eliminate perforation by surgery 43%. Other etiological factors were found: chronic polypous rhinosinusitis 14%, benign tumors 8%, allergic fungal sinusitis 5%. CONCLUSION: Clinical analysis showed that the development of most cases of odontogenic sinusitis is associated with the mistakes of dentists and is of iatrogenic origin. To prevent the development of odontogenic iatrogenic sinusitis, prior to dental interventions on the teeth of the upper jaw, it is necessary to carry out a topical diagnosis of their ratio with the maxillary sinus.

RESUMO

Introducción: La etiología de la sinusitis maxilar comprende diferentes causas primarias y secundarias. Siempre es preciso descartar de inicio aquellas causas iatrogénicas consecuencia de intervenciones previas. Objetivo: Realizar una revisión de las diferentes causas de sinusitis maxilar, con énfasis en las causas raras iatrogénicas y en el protocolo de actuación. Presentación del caso: Paciente varón de 60 años que presenta episodios de sinusitis maxilar. Como antecedentes quirúrgicos se había realizado quistectomía maxilar, tratamiento de fístula oroantral secundaria y rehabilitación protésica posterior. Tras estudio radiológico inicial se halló una masa intrasinusal, compatible al tacto con material de impresión dental. Conclusiones: Es importante antes de cualquier rehabilitación protésica y de la toma de modelos confirmar la ausencia de fístula oroantral para evitar la intrusión de material extraño en el seno maxilar(AU)


Introduction: The etiology of maxillary sinusitis comprises a number of primary and secondary causes. It is always necessary to initially rule out iatrogenic causes resulting from previous interventions. Objective: Carry out a review of the different causes of maxillary sinusitis, with an emphasis on the rare iatrogenic causes and the clinical management protocols. Case presentation: A male 60-year-old patient who experiences episodes of maxillary sinusitis. Surgical antecedents include maxillary cystectomy, treatment for secondary oroantral fistula and posterior prosthetic rehabilitation. Initial radiological examination revealed an intrasinus mass compatible to the touch with dental impression material. Conclusions: Before any sort of prosthetic rehabilitation and the taking of models, it is important to confirm the absence of an oroantral fistula, to prevent the entrance of foreign material into the maxillary sinus(AU)

RESUMO

This article shows the follow-up of several cases of maxillary sinusitis of dental (usually endodontic) origin, with different manifestations, diagnostic challenges, and outcomes.Cases from 14 patients from 3 countries and treated by 7 different endodontists are presented, all of them with inflammatory sinus changes represented by mucositis, osteoperiostitis, and/or partial/full obstruction. All cases showed dental and/or sinus signs/symptoms that resolved after dental management. In 13 cases, the sinus condition had an endodontic origin, 4 of them concurrently with periodontal involvement. In 1 case, sinusitis was caused by trauma to the face. All cases but 1 had a satisfactory response of the periradicular tissues and maxillary sinus to treatment that consisted of root canal therapy, root amputation, extraction, or trauma management.The successful management of most cases reported in this article emphasizes the importance of endodontics as a specialty engaged in saving teeth and promoting health not only in the oral cavity but also in other areas that may be affected by infections of endodontic origin, including the maxillary sinus.

RESUMO

PURPOSE: To present a case series treated by inferior meatal antrostomy as a prophylactic maneuver after the placement of zygomatic implants to decrease the risk of sinusitis. MATERIALS AND METHODS: All patients undergoing zygomatic implant placement using the lower meatal antrostomy protocol between June 2011 and March 2019 at the Department of Oral and Maxillofacial Surgery, Universidad El Bosque, were included. Patients were evaluated after 12 months of the procedure using clinical and radiologic criteria described by Kuriyama and Reiskin. RESULTS: Forty-eight patients were included, in whom 184 implants were placed. Complications were as follows: paresthesia (6.2%), orosinusal fistula (4.1%), skin infection (2.1%), and loss of the implant (1.6%). There were no cases of sinusitis. CONCLUSION: This study provides evidence that the technique is effective and should be considered because of its simplicity. The inferior meatal antrostomy has been proven to be a simple, effective, and reliable technique to decrease the risk of sinusitis associated with the placement of zygomatic implants.

RESUMO

In recent years, an increasing number of dental infections of the maxillary sinus has been observed. A prerequisite for a bacterial infection of the maxillary sinus is the perforation of Schneider's membrane. Pathogenetically, the ostiomeatal unit is only secondarily involved due to the infection ascending from the maxillary sinus floor. Besides the anamnesis, imaging procedures are important, whereby the high-resolution CT and CBCT (cone beam CT) have a special task due to their three-dimensional resolution. A dental X-ray or a dental examination for diagnosis is not sufficient in many cases. Due to the anatomy, the molars in particular are to be regarded as the cause of dentogenic sinusitis. The germ spectrum is polymicrobial with a dominance of anaerobes. Therapeutically, we favour one-stage surgery with rehabilitation of the underlying process and functional sinus surgery. Functional sinus surgery can also make a significant contribution to the rehabilitation of inflammatory complications in implantology.

RESUMO

The aim of this case report was to report the course of treatment for advanced paranasal sinus infection triggered by peri-implantitis, managed using functional endoscopic sinus surgery (FESS), with outcomes. A nonsmoking male patient received sinus augmentation with implant placement on his left posterior maxilla 15 years ago. Possibly due to noncompliance to maintenance, peri-implantitis developed and progressed into the augmented bone area in the maxilla. Eventually, maxillary sinusitis occurred concomitantly with a spread of the infection to the other paranasal sinuses. Implant removal and intraoral debridement of inflammatory tissue were performed, but there was no resolution. Subsequently, FESS was performed, with removal of nasal polyp and sequestrum. After FESS, the patient's sinusitis resolved. Histologically, the sequestrum was composed of bone substitute particles, necrotic bone, stromal fibrosis, and a very limited cellular component. Two implants were placed on the present site, and no adverse event occurred for up to 1 year after the insertion of the final prosthesis. Peri-implantitis in the posterior maxilla can trigger maxillary sinusitis with concomitant infection to the neighboring paranasal sinuses. FESS should be considered to treat this condition.

RESUMO

OBJECTIVES: To identify tooth diseases as potential causative factors in the development of maxillary sinus lesions, with the aid of clinical examination combined with Cone Beam Computed Tomography (CBCT), in the patients with persistent sinus-like ailments, unresponsive to routine treatment offered by otolaryngologists. MATERIALS AND METHODS: In 44 patients with suspected odontogenic maxillary sinusitis, a dental examination with tooth vitality test was carried out, in conjunction with CBCT. The study involved 29 women and 15 men (age range 19-69 years, mean age 43 (SD = 13.9) years). RESULTS: In 15 (34.1%) patients the odontogenic lesions were encountered in maxillary sinuses. A total of 33 causative teeth were identified, of which 13 (39%) were after root canal treatment (RCT). Only one of the teeth had a properly reconstructed crown, and only one tooth had the root canals properly filled-in. Most frequently, the lesions in the sinuses were attributed to the inflammation of periapical tissues; the first molar having been established as the most common causative tooth. CONCLUSIONS: A detailed dental examination, pursued in conjunction with CBCT analysis, allow to diagnose odontogenic maxillary lesions. The incidence of long-term ailments originating in the maxillary sinuses should prompt a detailed assessment of the teeth, especially those after RCT.

RESUMO

Eye globe rupture with consequent enucleation is an extremely rare complication of orbital infection spreading from maxillary sinusitis related to dental implant surgery. We report a case of orbital abscess leading to rupture of the globe of the eye in a 60-year-old woman with acute unilateral maxillary sinusitis after dental implant surgery on the left maxillary alveolar bone. The patient had uncontrolled diabetes. Despite surgical intervention, infection of the maxillary sinuses spread to the ocular area, causing disastrous results. To our knowledge, this entity has not been reported previously.

RESUMO

Transsphenoidal pituitary surgery is a safe, well-established treatment method, but it is associated with several postoperative nasal complications. However, gelatin sponge induced maxillary sinusitis after transsphenoidal pituitary surgery has not been reported. In this study, we present an unusual case of gelatin sponge induced maxillary sinusitis after transsphenoidal pituitary surgery. Therefore, it should be recognized that gelatin sponge induced maxillary sinusitis may occur as a complication after transsphenoidal pituitary surgery.

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

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

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

This fuller impact of the use of hyperbaric oxygen therapy within dentistry is taking greater notice with newer research findings. There are new advancements in research regarding postradiotherapy cases, osteonecrosis of the jaw, osteomyelitis, periodontal disease, and dental implants. Hyperbaric oxygen therapy can even be used in conjunction with other procedures such as bone grafting. Although the research and clinical utility has come a long way, there are several complications to be mindful of during the application of hyperbaric oxygen therapy.

RESUMO

Sinusitis is a recognised rare complication of palatine expansion procedures and is usually caused by the presence of an oroantral fistula. We report the first case of unilateral sinusitis as a result of a retained foreign body (a wooden spatula) following a surgically assisted rapid palatine expansion procedure.

RESUMO

Among humans, superiorly located maxillary sinus ostia (MSO) result in drainage complications and maxillary sinus (MS) disease. While previous studies investigate maxillary sinusitis frequency or MSO-position relative to specific nasal landmarks, few explore MSO-position to overall MS dimensions. This study investigates whether MSO-position relates to MS size/shape and if sex-based differences exist. Twenty-nine landmarks, placed on magnetic resonance images (MRIs) of 109 individuals (males = 57; females = 52), captured maximum dimensions of the cranium, MS, nasal cavity, and MSO-position relative to the MS floor (MSO_MSF) and nasal floor (MSO_NCF). Landmark coordinates were used to calculate centroid sizes and 13 linear distances; distances were size standardized by cranial centroid-size. Principal components analysis (PCA) on 3D-coordinates indicates that variation in MSO-position relates to superior-inferior MS positioning within the face (PC1 22% variance) and MS height (PC2 12% variance). Regression analyses indicate that MS size (r2 = 0.502; P < 0.001) and height (r2 = 0.589; P < 0.0001) strongly contribute to MSO_MSF: larger, taller MSs exhibit greater MSO_MSFs. Sex-based differences were not evident in PC shape-analyses nor among size-standardized dimensions. However, Mann-Whitney U-tests indicate females have absolutely smaller MSs (P = 0.001) and MSO_MSF distances (P = 0.001). Further, regressions indicate females exhibit lower MSO_MSFs for a similar MS height. Overall, MSOs superiorly placed relative to the MS floor correlate with larger, taller MSs and/or sinuses positioned inferiorly within the face. While craniofacial surgeons/clinicians should be aware of potential sex-based differences in MS size and MSO position, this study does not suggest that higher incidences of female-reported sinusitis relate to sex-based differences in MS anatomy.
