Objective: Researchers have extensively investigated the reasons behind variations in the volumes of paranasal sinuses, either among different individuals or between the right and left sides of the same individual. These differences in volumes have been associated with nasal septal deviation (NSD) and anatomical variations. In this study, we aimed to retrospectively analyzed the effect of NSD on frontal sinus, maxillary sinus, and sphenoidal sinus. Material and Method: A total of 281 patients (151 females and 130 males) admitted to Gaziosmanpaşa University Hospital were included in the study. Paranasal sinus computed tomography (CT) images consisting of 0.625-mmthick slices were obtained from the patients. The areas of the frontal sinus, maxillary sinus, and sphenoidal sinus were determined using ImageJ software. The volume of each sinus was calculated using Cavalieri's principle. We analyzed the relationship between the calculated volumes and nasal septal deviation. Results: Our study found that the frontal sinus volume values were 4.67 cm³ on the right side and 5.03 cm³ on the left side in women. In men, the right-side volume value was 7.07 cm³ and the left-side volume value was 7.77 cm³. The sphenoidal sinus volume value was calculated as 6.35 cm³ on the right side and 6.57 cm³ on the left side in women. In males, the right-side volume value was 7.34 cm³ and the left-side volume value was 7.62 cm³. The maxillary sinus volume was calculated as 19.38 cm³ on the right side and 19.37 cm³ on the left side in women. In males, the right-side volume value was 22.80 cm³ and the left-side volume value was 23.71 cm³. The frontal sinus volume values in males were larger than those in females (p=0.04). The maxillary sinus volume values in males were greater than the maxillary sinus volume values in females (p=0.02). There was no significant relationship between the presence of septal deviation and sinus volumes (p>0.05). The right, left, or s-shaped deviation direction did not cause a significant difference in sinus volumes (p>0.05). Conclusion: The findings show that there is no correlation between volume values and the presence and shape of nasal septal deviation. However, significant differences in volumes were observed between the genders. Because the severity of nasal septal deviation is related to the volume value, different results can be obtained by measuring the frontal sinus, maxillary sinus, and sphenoidal sinus volume values in individuals with more advanced deviation.

Objective: This study aimed to investigate the usability of the maxillary sinus as a criterion in gender determination by comparing the dimensions of the maxillary sinuses in adult males and females using cone-beam computed tomography (CBCT). Methods: Our study was designed to measure individuals' bilateral maxillary sinus height, width, and depth with CBCT. A total of 100 patients, 50 women and 50 men between the ages of 18 and 70, were included in the study. The height (H), width (W), and depth (D) of the sinus were measured in the coronal and axial planes, and their statistical significance was evaluated. Results: In our results, the confidence interval was determined as 95% and P < .05, was considered significant. Right height (P < .001), right width (P = .045), and left height (P = .015) parameters were statistically higher in males than in females. In the discriminant analysis, the parameter that gave the best discrimination was the right height with 63%. Conclusion: In our study, it was observed that the sinus maxillaris dimensions were larger in male individuals than in female individuals, but it was concluded that it is not a definitive criterion on its own and can be used as a supporting one.

Non-Hodgkin’s lymphomas are rare forms of the head and neck malignancies. It is often accidentally diagnosed or in an advanced phase by the onset of clinical symptoms. It is possible to diagnose it during stomato-oncological screening if it is to spread towards the oral cavity. This paper presents the diagnostic steps, oncological care, and complete dental rehabilitation of a patient, with diffuse large B-cell lymphoma localised in the maxillary sinus. The course of the treatment was mainly determined by the patient’s underlying disease. At the end thanks to the early diagnosis and the successful oncological treatment, started on time, the tumour showed complete remission and after eighteen months, no relapse occurred. The patient’s general condition is good, he is satisfied with the completed dental restorations and dental works and he is regularly monitored by his doctors.

Objectives: To evaluate, by comparing maxillary sinus volumes, how asymmetries related to oculoauriculovertebral spectrum (OAVS) affect upper-jaw development.Methods: From pre-existing multislice spiral computed tomography (MSCT) datasets, we selected 20 cases of 11 female and 9 male patients aged 6.1-24 years who were clinically and radiographically symmetrical (group 1) plus 20 cases of 8 female and 12 male patients aged 5.7-23.9 years who had OAVS (group 2). After three-dimensional reconstruction of the datasets, the volumes of the left and right maxillary sinuses were calculated and compared based on patient groups and based on the sides affected or unaffected by OAVS. To this end, the OAVS patients were subdivided into a group in whom both external acoustic pores were radiographically present (group 2a) and a group in whom the pore on the affected side was congenitally missing (group 2b).Results: Intrarater reliability was very high (0.997). Significantly larger volumes of the maxillary sinuses, amounting to a mean of 13.4 ml, were observed in the control group than in the asymmetric OAVS groups where the volumes averaged 9.8 ml or 10.3 ml, respectively (p = 0.03). No statistically significant differences in sinus volumes were found between the two OAVS groups (p = 0.557) and between the sides affected or unaffected by the OAVS (p = 0.8311 in group 2a and 0.4961 in group 2b).Conclusions: Overall, we found the volumes of both maxillary sinuses to be somewhat smaller in the asymmetric patients than in the symmetric control group. This might indicate that OAVS was associated with a mild generalized hypoplasia of the maxilla, but significantly different sinus volumes were not seen between the affected and unaffected sides.

Összefoglaló. Az utóbbi időben egyre gyakoribbá vált fogászati implantáció egyik nem kívánt szövődménye az arcüregbe került implantátum, amely a maxilla molaris, esetenként praemolaris régiójának implantációjakor fordulhat elő. Ennek oka lehet a kúpsugaras komputertomográfia nélküli, azaz nem megfelelő tervezés, fennálló arcüreggyulladás és -ventilációs probléma, kevés, puha csont, a fúrási vagy implantátumbehelyezési sebészi gyakorlat hiánya, észre nem vett membránperforáció arcüreg-csontfeltöltés esetén. Esetünkben implantáció előtt a beteg szájsebész orvosa kúpsugaras komputertomográfia alapján sinusventilációs zavart és arcüreggyulladást véleményezett. Az arcüreggyulladás funkcionális endoszkópos sinussebészeti műtéttel történő kezelését és gyógyulását követően két lépésben, először arcüreg-csontfeltöltést, majd 6 hónappal később implantációt végeztek. 4 hónap panasz- és tünetmentes gyógyulást követően az implantátumfeltárás előtt derült fény az arcüregbe került implantátumra, amelyet funkcionális endoszkópos sinussebészeti eljárással, transnasalis (Lothrop) és intraoralis behatolás kombinációjával távolítottunk el. Az implantátumok arcüregbe kerülésének gyakorisága továbbra is ismeretlen, a szakirodalomban kb. 70 közölt esetről tudunk; a leggyakrabban egy-egy implantátummal kapcsolatban születnek cikkek, ami az összes beültetett implantátum számához képest elenyésző. Az arcüregben lévő szabad implantátum arcüreggyulladást okoz, eltávolítása szükséges, kötelező. A sinus hátsó részében elhelyezkedő implantátum esetén elsősorban funkcionális endoszkópos sinussebészeti eljárás javasolt. Az első recessusban lévő implantátum eltávolítására a legjobbnak a praelacrimalis recessusból végzett korszerű behatolás tűnik. Tradicionális transoralis/Luc-Caldwell-féle behatolást a friss sinuslift utáni gyulladt csontexcochleatio esetén javasolunk, illetve ha fennálló oroantralis fistulát is zárnunk kell. Orv Hetil. 2022; 163(13): 527-531. Summary. Accidental implant displacement into the maxillary sinus is often due to inappropriate surgical planning or technique, unrecognised sinus disease, failure to recognise low residual bone quality and quantity during implant-supported maxillary molars and premolars rehabilitation. Secondary implant migration can be attributed to the risk of failing osteointegration due to unnoticed sinus membrane rupture during surgery, incomplete soft tissue closure over the implant's site, preexistent sinus ventilation problems. In this study, we present the case of a patient with a symptomless preexistent sinus infection, which had been treated with functional endoscopic sinus surgery. After the healing period, the following two-stage procedures were performed: 1) maxillary sinus bone augmentation, 2) 6 months later dental implant placement, based on a routine orthopantomogram. At the end of the 4-month planned healing period, the implant displacement was noticed in the sinus cavity. The implant was removed with a combination of endoscopic surgery, transnasal and transoral Luc-Caldwell approach. The possible reasons for displaced implant into the sinus cavity, the treatment decision tree and lessons we learned, updated by the international literature, are discussed. Our recommendation for displaced implant removal is primarily transnasal under general anaesthesia. In the case of the implant in the anterior recess of the maxillary sinus, the functional endoscopic sinus surgery through the prelacrimal recess approach seems to be the preferred approach. A transoral approach should be the chosen method in the case of present oro-anthral fistulae or recent sinus bone graft, when the infected graft should also be removed.

Beschrieben wird der Fall einer 47 jährigen Patientin, die seit 5 Jahren zunehmend an den Symptomen einer Dakryostenose litt. Dakryozystographie, NNH-Tomographie, Schädel-CT sowie Biopsie des unteren Nasenganges ergaben ein plexiformes Ameloblastom des Sinus maxillaris, dessen Infiltration in die Orbita und die ableitenden Tränenwege zur Stenosierung des Tränenkanals führte. Über eine laterale Rhinotomie erfolgte die In- toto- Exzision des Tumors. A 47-year-old woman had typical symptoms of dacryostenosis for 5 years. Dacryocystography, sinustomography, computerized tomography scan and biopsy of the lower nasolacrimal duct confirmed the diagnosis of a plexiform ameloblastoma of the maxillary sinus. The infiltration of the orbit and the nasolacrimal duct by the tumor caused the stenosis of the lacrimal drainage system. A total excision of the ameloblastoma was performed as a lateral rhinotomy.
