Abstract:
The aim of the study was to evaluate the results and 4-year own experience in the endoscopic treatment of the nose and paranasal sinuses. In the Clinic of Otolaryngology and Laryngological Oncology of the Medical University of Lodz between 2006 and 2009 there were 603 endoscopic operations performed on patients with chronic paranasal sinusitis, including 287 females aged 17–80 and 316 males aged 18–87. The patients were qualified for the operation on the basis of an interview, objective otorhinolaryngological examination, frontal and transverse computerized tomography of the nose and paranasal sinuses, laboratory tests (blood cell count, sedimentation tests, urine tests, electrolytes tests). Moreover, allergological diagnostics (skin prick tests, intranasal provocation tests), a histopathological examination of the removed lesions and a culture of biological material from the paranasal sinuses were done. The 0° and 30° endoscopes of Storz GMBH and Wolf and the video rotation microtome (debrider). Possible reasons for paranasal sinusitis were: viral infection (34.8%), anatomical disorders (28.5%), irritating factors like tobacco smoke (17.9%), allergy (13.4%), tumours (3.2%) and gastroesophageal reflux (2.1%). Finally, the following endoscopic operations were conducted: revision surgery of the maxillary sinuses in 680 cases (56.4%), ethmoidectomy in 586 cases (48.6%), polypectomy in 273 cases (22.6%), re-polypectomy in 232 cases (19.2%), sphenoid sinus revision in 229 cases (19.0%), frontal sinus revision in 80 cases (6.6%) and re-ethmoidectomy in 77 cases (6.4%). The average stay in the Clinic lasted 3.2 days. Advantages of the complex surgical treatment are found in both post-operative and pharmacological procedures. The FESS surgery should be only a minimally invasive technique, which subsequently could guarantee an effective treatment, slight post-operative complications, a short hospitalization period and a quick return of the patient to work, as it is proved by the own study.Keywords:

Objective: To improve the diagnosis and treatment of fungal sinusitis. Methods:Clinical data of 19 patients with fungal sinusitis were reviewed retrospectively. Results: Of 19 patients, the infected sites were all in unilateral nasal sinus. 12 cases presentiod in maxillary sinus, 2 cases presented in ethmoid sinus, 1 case presented in sphenoid sinus, 3 cases involved over two nasal sinuses, and 1 case involved over three nasal sinuses. CT scan showed 15 cases (78.9%) had a calcified area inside in nasal sinus, 5 cases had bone destructive. 3 cases recurrence occurred as followed within 2 years after operation. Conclusion:Fungal sinusitis usually occurred in unilateral nasal sinus, especially in maxillary sinus. CT has very important value for its diagnosis. Surgical management is effective in the treatment of fungal sinusitis.

A strategic surgical approach is necessary for patients who cannot undergo maxillary sinus augmentation due to a large perforation of the sinus membrane as a result of complex sinus septa. The technique includes partial cutting and removal of the sinus septum and graftless mucosal elevation of the concavity area. Six months after the procedure, bone growth was observed in the area where the septum had been partially removed. The sinus mucosa was slightly thicker because of scarring; consequently, maxillary sinus augmentation was safely achieved. This two-step procedure is effective for safe maxillary sinus augmentation in patients with complex sinus morphology.

This study was conducted to produce a 3-dimensional reconstruction using multidetector computed tomography (MDCT) images of the anatomic structures forming the paranasal sinuses of New Zealand rabbits and to present biometric properties of the sinuses and conchae. A total of 16 adult New Zealand rabbits, comprising 8 males and 8 females, were included in the study. After high-resolution MDCT images of the paranasal sinuses were obtained, they were reconstructed using a 3-dimensional modeling program (Mimics) by overlapping the images and the biometric measurements of the structures forming the paranasal sinuses. The maxillary sinuses of New Zealand rabbits were made up of 2 compartments. It was also observed that their conchae were more developed with an uneven structure. The frontal sinus and sphenoid sinus were not seen and the ethmoid sinus was not observed. There was not a significant statistical difference between sinus and conchae constituting the right and left paranasal sinuses of the same sex; however, a significant statistical difference was observed between the sexes (P < 0.05). This study’s data can be used for purposes of modern anatomy education and research and may form a basis as a model for future studies to be performed on the paranasal sinuses.

Purpose: Maxillary sinus elevation has been widely used to enable insertion of endosseous implants in severely resorbed maxilla. Maxillary sinusitis after this procedure was considered to be the major drawback, therefore, preoperative evaluation of paranasal sinus is considered to be important. In order to evaluate the condition of the sinus, we used Waters' projection. In this study, asymptomatic patients were evaluated by Waters' view, and compared to timing to assess the sinus cavity. Methods: The retrospective study was based on 14 patients who were performed sinus elevation surgery in Seoul National University Dental Hospital. These patients did not show any signs of maxillary sinusitis. These patients were taken Waters' view at preoperative, postoperative 1 day, 3 months, 6 months. In Waters' view, presence of air fluid level, radiopacity of sinus wall, or radiopacity of entire maxillary sinus were evaluated. The density, and sinus dimension changes were assessed using Adobe Photoshop CS5$^{(R)}$ (Adobe Systems Inc., San Jose, CA, USA). Results: Findings of Waters views in patients with clear maxillary sinus at preoperative time were followed by elevated sinus floor with transplanted bone, mucosal swelling, and air fluid level. At postoperative 3 months, and 6 months, the radiographic findings were similar to preoperative state. By contrast, patients with preoperative mucosal swelling, or haziness in sinus cavity showed radiopacity entire sinus in Waters' view. In cases of the patients who were treated with simultaneous treatment to mucosal swelling, good status of sinus cavity were found. Conclusion: Although Waters' projections provide the limited information, and is less sensitive method compared with computed tomography, it is simple, easy, and economical method to assess of maxillary sinus. We suggest using Waters' view as radiographic routine tool for evaluation of sinus condition, especially in the sinus elevation surgery.

Although a variety of theories have been proposed about functions of the paranasal sinuses, not one is clear today. Nonetheless, paranasal sinus-related diseases are associated with a high rate of morbidities. Therefore, it is essential to identify the structure and pathophysiology of the paranasal sinuses. Computed tomography (CT) is a valuable tool displaying anatomic variations and diseases. Because paranasal sinus development is a complex and long-lasting process, there are great structural variations between individuals. Several degrees and combinations of aplasias and hypoplasias have been reported; however, there is only one case of total paranasal sinus aplasia in the literature. Here, we present the second case of total paranasal sinus aplasia. Paranasal sinus development, functions of the paranasal sinuses, and the role of CT were evaluated.

A three-dimensional morphology of the maxillary sinus was reconstructed. We studied the relationship between sinusitis and three-dimensional morphology, volume as well as gasification coefficients.One hundred and fifty adult subjects were selected in this study, and divided into three groups: normal bilateral maxillary sinus, unilateral maxillary sinusitis and bilateral maxillary sinusitis, with fifty cases in each group. Use Siemens helix CT for sequential scanning of the nasal-sinus. After scanning, the DICOM data was recorded in DVD-R and transferred into another computer for reconstruction and measurement.The volume of the normal maxillary sinus group was (15 018.64 +/- 473.36) mm3. The volume of the maxillary sinusitis group was (14 971.86 +/- 360.93)mm3. There was no significant difference between the values of volumes for the normal maxillary sinus group and maxillary sinusitis group. The gasification coefficient was 0.345 +/- 0.071 for the normal maxillary sinus group, 0.252 +/- 0.057 for the maxillary sinusitis group. There was significant difference between the two groups.Maxillary sinus reconstruction permits more vivid visualization of the three-dimensional structure and three-dimensional shape of the maxillary sinus. The occurrence of the maxillary sinusitis is closely related to the three-dimensional shape of the maxillary sinus and the gasification coefficient measured. The more regular the three-dimensional shape of the maxillary sinus, with the gasification coefficient >0.300, the lower the probability of the maxillary sinusitis. Otherwise, the probability increases. Adult inflammation of maxillary sinus may be originated from a relatively larger volume of maxillary sinus in childhood and adolescence.
