AbstractObjectives:Endoscopic sinus surgery has been widely performed to treat nose and paranasal diseases. However, it is difficult to manipulate anterior wall lesions of the maxillary sinus using conventional surgical instruments. This paper presents a method of performing endoscopic surgery for anterior wall lesions of the maxillary sinus, using a 135° reflective CO2 laser.Method:A CO2 laser with a 135° reflective tip on the pipe-guide handpiece and a CO2 laser angulated to the same degree were used. The pipe-guide handpiece with reflective tip was inserted into the nasal cavity and the base of the maxillary sinus anterior wall lesion was vaporised and removed via an enlarged natural ostium. During the procedure, the maxillary antrum was visualised with a 70° endoscope. Ten cases of maxillary sinus anterior wall lesion underwent this surgical procedure.Results:In all cases, the base of the maxillary sinus anterior wall lesion was removed completely and recurrence avoided.Conclusion:This method is a reliable procedure enabling endoscopic sinus surgery for anterior wall lesions of the maxillary sinus.

Ameloblastoma (AM) in the maxillary sinus is rare. This benign entity shows locally invasive, destructive and aggressive behaviour and a high rate of recurrence. Therefore, the course of treatment is radical resection. We report the case of a 38-year-old man presenting with signs of recurrent sinusitis in the Ear, Nose and Throat Department. Transnasal flexible endoscopy revealed a cystic mass in the right inferior and middle nasal passage. CT scan showed an obliterated right maxillary sinus with a ballooning effect and pressure atrophy of the lateral sinus wall, without possible differentiation of the middle and low nasal turbinate. The patient was treated with transnasal functional sinus surgery; pathology stated AM. AM in the maxillary sinus is rare, locally destructive and therefore as a gold standard is resected radically to prevent recurrence. We demonstrate a conservative approach; explicitly, we combined a transvestibular and functional endoscopic sinus surgery resection of the AM to maintain function and reduce the possibility of postoperative impairments. Whether the strategy of treatment for AM is conservative, it nonetheless can result in a recurrence-free status. Nevertheless, inclusion into an oncological follow-up-programme with regularly performed MRI and CT is recommended.

The author notes some, partly not new, but only forgotten, signs of maxillary sinus polyps, namely, 1) ease of probing the latter from the middle nasal passage, depending on the abnormal width of ostii accessorii; 2) feeling from the side of the sinus, when touching it with the probe, of a kind of resistance when pressing on the polyposis mucosa, - a typical sign, but not described anywhere else; 3) "staining" in the area of the affected sinus, with air gaps between the spots on the radiograph, - a phenomenon explained by the fact that the darkening here is the result of exudate, but the presence of mucosal polyps.

Inflammatory myofibroblastic tumor (IMT) is a rare condition that can mimic potentially more dangerous states such as malignant tumors. The tumor itself can also show a local malignancy as well as malignant transformation. The paranasal sinus IMT is quite a rare case in the literature. The manifestation of the disease can include a face swelling, nasal obstruction, epistaxis, vision acuity worsening, numbness of face, pain. Etiology of this type of lesion still remains uncertain but there are a few assumptions on the issue: viral and genetic among the others, as well as posttraumatic and postinflammatory. We report the case of an adult woman with IMT detected in right maxillary sinus after endoscopic sinus surgery.

The purpose of the study was to give a clinical evaluation of the effectiveness of endonasal blockade of the nasopalatine nerve in different ways during radical maxillary sinusotomy in dental patients. Materials and methods. Clinical observations were performed in 50 patients diagnosed with chronic odontogenic maxillary sinusitis. Radical maxillary sinusotomy was performed under local potentiated anesthesia. All patients underwent anesthesia on the maxilla according to classical methods. Patients, depending on the methods of endonasal blockade of the nasopalatine nerve, were divided into two clinical groups: the main (24 people) and the comparison group (26 people). Patients of the main group underwent endonasal blockade of the nasopalatine nerve at the site of its branch from the pterygopalatine ganglion. In patients of the comparison group, the blockade of this nerve was performed before its entry into the incisal canal. The effectiveness of anesthesia was evaluated for clinical and autonomic manifestations of pain stress. Results and discussion. During the removal of polyps and pathological granulations from the mucous membrane of the maxillary sinus in patients of the main group there was no pain, no emotional-motor and autonomic manifestations of pain stress, which confirmed the effectiveness of the endonasal method of anesthesia of the nasopalatine nerve. In patients of the comparison group during similar surgical manipulations the full effect of local anesthesia was achieved in 50.0% of cases (χ2 – 8.065, р = 0.005). These were patients who had hypopneumatized or moderately pneumatized types of maxillary sinuses. The rest of the patients during the operation had emotional – motor and autonomic manifestations of pain stress during the removal of pathologically altered mucous membrane located on the medial wall of the maxillary sinus. Conclusion. Complete anesthesia of the mucous membrane, maxillary sinus, regardless of the degree of its pneumatization is achieved during the usage of endonasal blockade of the nasopalatine nerve at the site of its branch from the pterygopalatine ganglion during radical maxillary sinusotomy in dental patients. Anesthesia of the nasopalatine nerve in the lower nasal passage, before its entry into the incisal canal, allows painless surgery only in patients with hypopneumatized maxillary sinuses and in most patients with moderate pneumatization

The maxillary sinus cysts are a fairly common pathology of the paranasal sinus system, which has a multifactorial etiology that continues to be actively investigated. In recent years, particular attention of researchers has focused on the role of chronic inflammation of the root of the teeth, which are directly adjacent to the lower wall of the maxillary sinus, and accordingly involve the surrounding structures in the pathological process. One of the objective indicators of the severity of inflammation is the level of matrix metalloproteinases, in particular matrix metalloproteinase 9 (MMP-9). Аs follows, the purpose of the study is to study of efficiency of treatment of patients with cystic sinus cysts of odontogenic origin in the long term. Materials and methods. The study included 150 patients. Group 1 - 125 people (age 20-69 years, men - 58, women - 67), group 2 - 25 patients (age 21-59 years, 11 men and 14 women). All patients from the examined groups underwent surgical treatment - removal of the cyst of the maxillary sinus through the lower nasal passage, with subsequent conservative treatment; patients of the first group in the postoperative period were audited channels of the teeth of the upper jaw with replacement of the filling material, and patients of the second group this intervention was not carried out. The inclusion criterion is an increase in the level of ММП-9 in saliva. The exclusion criteria were the presence of acute disease 3 months before surgery, treatment with the dentist 3 months before surgery, normal level of MMP-9 in saliva. In the course of preoperative preparation, all patients underwent CT scan of the paranasal sinuses, endoscopic examination of the nasal cavity and nasopharynx, rhinopneumometry, determination of the index of mucociliary clearance, activity of MMP-9 in saliva. The study of MMP-9 activity in saliva was performed using ELISA kit. Statistical data processing was performed using IBM SPSS Statistics 22. Conclusion. The level of ММР-9 in the saliva of patients of the first group was 1347 (± 328) ng / ml, the second - 1410 (± 220) ng / ml. The number of recurrences of sinus cyst in group 1 was 8, accounting for 6.4% of the total. Other complications include sinus mycetoma - 4 oroantral fistula - 1, hoonal polyp - 2.. The number of relapses of the sinus cyst in group 2 was 9 cases (36%), mycetoma of the sinus cyst - 3 cases, oroantral fistula - 1, hoonal polyp - 1. Conclusion. The results obtained indicate a higher likelihood of recurrence of the maxillary sinus cyst in the absence of a subsequent revision of the root of the teeth and around the root areas immediately adjacent to the lower sinus wall.

Aim - to show the clinical observation of the development of odontogenic maxillary sinusitis in case of entering the sinus of the root of the tooth. Materials and methods. The results of the study - video endoscopy of the nasal cavity and CT of the paranasal sinuses - were evaluated. The obtained data pointed to the foreign body that caused not only an inflammatory process with subsequent development of the mycetoma, but also destruction of the medial wall of the maxillary sinus, the inferior nasal concha. Access to the maxillary sinus was discussed, and surgical intervention was performed. Conclusions. The root of the tooth was extracted through the developed defect of the medial wall of the maxillary sinus communicating with the lower nasal passage.
