Extended endoscopic approaches to the maxillary sinus

AbstractObjectivesTreatment of inflammatory and neoplastic disease in the maxillary sinus, pterygopalatine and infratemporal fossae requires appropriate surgical exposure. As modern rhinology evolves, so do the techniques available. This paper reviews extended endoscopic approaches to the maxillary sinus and the evidence supporting each technique.MethodsA literature search of the Ovid Medline and PubMed databases was performed using appropriate key words relating to endoscopic approaches to the maxillary sinus.ResultsMega-antrostomy and medial maxillectomy have a role in the surgical treatment of refractory inflammatory disease and sinonasal neoplasms. The pre-lacrimal fossa approach provides excellent access but can be limited because of anatomical variations. Both the transseptal and endoscopic Denker's approaches were reviewed; these appear to be associated with morbidity, without any significant increase in exposure over the afore-described approaches.ConclusionA range of extended endoscopic approaches to the maxillary sinus exist, each with its own anatomical limitations and potential complications.

According to International Society for the Study of Vascular Anomalies classification 2018, “hemangioma” should be classified as either vascular tumor or vascular malformation (VM). So-called “cavernous hemangioma” is categorized as VM. VM rarely involves the mucous membranes of the sinonasal cavity and typically arises unilaterally from the sinonasal cavity. Bilateral VM of the maxillary sinus is extremely rare. To the best of our knowledge, there is no previous report of bilateral VM of the maxillary sinus. Here, we describe the surgical treatment of bilateral cavernous hemangiomas of the maxillary sinus. These tumors were successfully resected by endoscopic modified medial maxillectomy (EMMM) after embolization. Endoscopic sinus surgery, particularly EMMM, produces access to the bilateral maxillary sinus and can prevent several complications.

OBJECTIVE: Caldwell and Luc described the Caldwell-Luc operation more than 100 years ago as the surgical treatment for maxillary sinus disease. During the last decades less radical interventions using endoscopic approach have mainly replaced the classical procedures done for chronic and recurrent maxillary sinusitis. STUDY DESIGN AND SETTING: Between 1991 and 2002, 62 patients had the Caldwell-Luc approach for different indications. RESULTS: Twenty (32%) patients had chronic sinusitis, 16 (26%) patients had inverted papilloma, 9 (15%) patients had suffered from nasal polyposis, 4 patients (6%) had dentigerous cyst, 4 (6%) patients had fungal ball, and 9 (15%) patients were operated for other indications. CONCLUSIONS: The use of this surgical approach is rational in cases of fungal disease and in endoscopic medial maxillectomy for treating inverted papilloma. In all other cases, the preferred approach should now be endoscopic.

Increased Risk

Preoperative evaluation of maxillary sinus anatomy is very important to avoid surgical complications due to close anatomical relations between the sinus and the posterior maxillary teeth and/or edentulous alveolar ridge. Posterior superior alveolar artery is a branch of the maxillary artery and provides the vascularization of the lateral sinus wall and underlying mucosa. Maxillary artery branches should be taken into consideration during sinus lifting procedures and bone augmentation due to increased risk of bleeding by damaging the artery during the osteotomy. Computed tomography (CT) explores three-dimensional anatomic structures and provides complex and accurate information about them. Cone Beam Computed Tomography (CBCT) offers an accurate view of the teeth and surrounding structures at high resolution, despite low-dose radiation used. In this study, the incidence of anatomical variations and sinus pathology were assessed using CBCT. The aim is to evaluate the presence of sinus pathology (sinus mucosal thickening, oro-antral communications, sinus tumors, cysts, polyps), presence and position of the posterior superior alveolar artery. These issues are important because they are about the limits of the dental implants in the posterior maxillary area. The presence of sinus pathology and anatomical variations may predispose to complications and even failures of implantation therapy.

High Prevalence

Today, around 50 million people worldwide suffer from cataracts, more than a half of them need surgical treatment. High prevalence of this pathology in Ukraine, the need to improve the provision of ophthalmic care to patients, and the reform of the health care system have made the research relevant. Concomitant diseases and special conditions of the eye increase the risk of intra− and postoperative complications, worsen the functional parameters of patients after surgery. In order to develop a unified approach to the treatment of complicated cataracts based on diagnostically related groups of patients, a retrospective analysis of case histories of patients with different variants of complications related to the condition of the lens itself, its ligament apparatus and other structures of the eye was conducted. In each case, the surgeon has to choose the appropriate modification of cataract phacoemulsification surgery. The study proposed the classification of cataract phacoemulsification modifications on the basis of the techniques and the sequence of operation stages, taking into account the classification of the degrees of turbidity of the lens, proposed by L. Buratto. It has been noted that in complicated cases, according to the indications of the patient, surgery may be performed on several modifications of cataract phacoemulsification. The developed classification made it possible to generalize the various variants of pathology and greatly facilitate the choice of tactics of surgical treatment in complicated cataracts. It can be used not only for practical application, but also for improving the qualification of trained professionals. The prospect of further research is to identify contraindications for outpatient treatment of the patients with complicated cataracts. Key words: cataract complication, classification of phacoemulsification modifications, diagnostically related groups.

RESUMOO dente denominado incluso nada mais é que um dente retido ou impactado dentro do alvéolo dentário de maneira parcial ou completa que não conseguiu erupcionar por motivos patológicos ou simplesmente anatômicos após o período de rizogênese. O canino, em especial, é de suma importância sob os pontos de vista estético e funcional. O deslocamento do canino incluso ultrapassando, ou se aproximando da linha média antes da erupção dentária do mesmo, é mais frequente na mandíbula do que na maxila. Este trabalho tem por objetivo descrever o caso de um paciente de 21 anos que apresentava um canino incluso na região mentual, em posição transversal, inicialmente visualizado em uma radiografia periapical e posteriormente submetido a radiografia com a técnica de Donavan. Através de uma radiografia oclusal, foi possível observar o posicionamento do dente para a vestibular mentoniana e íntima relação do dente retido com as raízes dos incisivos centrais decíduos do paciente. Foi realizada a extração do dente retido no mento, removendo o mesmo por completo sendo feitas osteotomias e odontossecções. O paciente está em acompanhamento clínico à 1 ano após o tratamento cirúrgico.Palavras – chave: Dente incluso; Cirurgia Oral; Imaginologia. ABSTRACTThe tooth inserted is nothing more than a tooth retained or impacted within the dental socket partially or completely that failed to erupt for pathological or simply anatomical reasons after the period of rhizogenesis. The canine, in particular, is of the utmost importance from the aesthetic and functional points of view. The displacement of the canine, even surpassing or approaching the midline before tooth eruption, is more frequent in the mandible than in the maxilla. This work aims to describe the case of a 21 - year - old patient who had a canine included in the mental region, in a transverse position, which was initially visualized on a periapical radiograph and later submitted to radiography with the Donavan technique. An occlusal radiograph showed the positioning of the tooth for the mental vestibular and the intima relationship of the retained tooth with the roots of the patient's central deciduous incisors. Removal of the tooth retained in the denture was performed, removing the tooth completely and osteotomies and odontosections were performed. The patient is in clinical follow-up at 1 year after the surgical treatment. key words: Tooth included; Oral surgery; Imaginology.

Angiosarcomas are rapidly growing malignant neoplasms arising from the vascular endothelial cells. Most common sites are the extremities and the retroperitoneal space, with only four per cent of angiosarcomas arising in the head and neck area, whilst the paranasal sinuses are one of the rarest locations. We report the case of a maxillary sinus angiosarcoma in a 72-year-old male patient. The first biopsy was inconclusive, whereas the second revealed an angiosarcoma. Medial maxillectomy was performed with subsequent external irradiation.
