ABSTRACT Objectives: To evaluate the maxillary sinus volumes in unilaterally impacted canine patients and to compare the volumetric changes that occur after the eruption of canines to the dental arch using cone beam computed tomography (CBCT). Materials and Methods: Pre- (T0) and posttreatment (T1) CBCT records of 30 patients were used to calculate maxillary sinus volumes between the impacted and erupted canine sides. The InVivoDental 5.0 program was used to measure the volume of the maxillary sinuses. The distance from impacted canine cusp tip to the target point on the palatal plane was also measured. Results: Right maxillary sinus volume was statistically significantly smaller compared to that of the left maxillary sinus when the canine was impacted on the right side at T0. According to the T1 measurements there was no significant difference between the mean volumes of the impaction side and the contralateral side. The distance from the canine tip to its target point on the palatal plane were 17.17 mm, and the distance from the tip to the target point was 15.14 mm for the left- and right-side impacted canines, respectively, and there was a significant difference between the mean amount of change of both sides of maxillary sinuses after treatment of impacted canines. Conclusions: Orthodontic treatment of impacted canines created a significant increase in maxillary sinus volume when the impacted canines were closer with respect to the maxillary sinus.

Abstract Introduction The endoscopic access to lesions in the anterolateral wall of the maxillary sinus is a challenging issue; therefore, the evaluation of access should be performed. Objective To assess the accessibility of three endoscopic ipsilateral endonasal corridors. Methods Three corridors were created in each of the 30 maxillary sinuses from 19 head cadavers. Accessing the anterolateral wall of the maxillary sinus was documented with a straight stereotactic navigator probe at the level of the nasal floor and of the axilla of the inferior turbinate. Results At level of the nasal floor, the prelacrimal approach, the modified endoscopic Denker approach, and the endoscopic Denker approach allowed mean radial access to the anterolateral maxillary sinus wall of 42.6 ± 7.3 (95% confidence interval [CI]: 39.9–45.3), 56.0 ± 6.1 (95%CI: 53.7–58.3), and 60.1 ± 6.2 (95%CI: 57.8–62.4), respectively. Furthermore, these approaches provided more lateral access to the maxillary sinus at the level of the axilla of the inferior turbinate, with mean radial access of 45.8 ± 6.9 (95%CI: 43.3–48.4) for the prelacrimal approach, 59.8 ± 4.7 (95% CI:58.1–61.6) for the modified endoscopic Denker approach, and 63.6 ± 5.5 (95%CI: 61.6–65.7) for the endoscopic Denker approach. The mean radial access in each corridor, either at the level of the nasal floor or the axilla of the inferior turbinate, showed a statistically significant difference in all comparison approaches (p < 0.05). Conclusions The prelacrimal approach provided a narrow radial access, which allows access to anteromedial lesions of the maxillary sinus, whereas the modified endoscopic Denker and the endoscopic Denker approaches provided more lateral radial access and improved operational feasibility on far anterolateral maxillary sinus lesions.

Abstract Background and aims : Measurements of the maxillary sinus volumes in computed tomography (CT) scans can be used for determination of gender when other methods are inconclusive. Maxillary sinus dimension measurements are valuable in studying sexual dimorphism and can assist in gender determination. The radiographic images can provide adequate measurements for maxillary sinuses that cannot be approached by other means. The purpose of the present study was to determine and compare the volume of the maxillary sinus between males and females of Tamil Nadu region using CT scans. Materials and methods : This study was carried out by using CT images of head region of 100 males and 100 females who underwent CT scanning for indications other than the pathology of the maxillary sinuses. The CT images obtained were of patients between 20 to 50 years of age. The maxillary sinus volume of each side were calculated by using the following formula: Maximal width X Maximal height X Maximal depth X 0.5. Comparison of data between genders and sides was done. The statistical inference was derived by applying unpaired student "t" test and the p value was obtained (p value <.05 was considered statistical significant). Results: Oncomparison of males with females, the mean volumes of maxillary sinuses on each side (left and right) had shown a statistically significant difference (p<.OOOl ). The maxillary sinus volumes of the males were found to be significantly higher than that of the females. Among males, the average mean volume of maxillary sinuses (right + left) is 15.15 ± 0.45 cm3. Among females, the average mean volume of maxillary sinuses (right + left) is 12.77 ± 1.34 em' which is significantly lesser than that of the males. Conclusion : It can be concluded that the volumes of the maxillary sinuses of males are larger than those of the females and this difference is statistically significant. Maxillary sinus dimension measurements can assist in gender determination.

OBJECTIVE: To evaluate change of the maxillary sinus volume according to patient age and gender by using a 3-dimensional (3-D) reconstruction of computed tomography images. STUDY DESIGN AND SETTING: One hundred seventy-three people (totaling 238 maxillary sinuses) who had undergone paranasal sinus CT scan between December 2000 and November 2003 and had no evidence of inflammation or hypoplasia in the CT finding and had no specific history of paranasal sinus surgery or maxillofacial trauma were retrospectively analyzed. The 3-D reconstruction images were obtained by using a surface-rendering technique (Vworks; CybeMed, Seoul, Korea) on a personal computer. The mean volume of maxillary sinus was evaluated according to patient chronologic age and gender. The ratio of the maximum horizontal and half-horizontal extension for the estimation of the morphological change of maxillary sinus and the degree of descent of the sinus below the nasal floor were evaluated in the 3-D image. RESULTS: The development of the maxillary sinus continued until the 3rd decade in males and until the 2nd decade in females. The mean maxillary sinus volume in early adults was 24,043 mm 3 (males) and 15,859.5 mm 3 (females). There was a significance difference in the sinus volume ( P < 0.05) according to gender, and there was a significant difference in the maxillary sinus volume according to age before it reached maximum. After its maximum growth period, however, there was no significant difference in the volume change of maxillary sinus and the descent below the nasal floor between two adjacent groups. CONCLUSIONS: The growth of the maxillary sinus continues until the 3rd decade in males and the 2nd decade in females. Therefore, a maxillary sinus operation affecting the bony structures before these ages might affect the development of the sinus and needs to be performed carefully

Objective: The purposes of this study were to evaluate and compare the maxillary sinus volume (MSV) of patients with a unilateral cleft lip and palate (UCLP) between the cleft side and noncleft side and between adolescent patients with UCLP and a control (noncleft) group using cone beam computed tomography (CBCT). Methods: CBCT images of 44 UCLP patients (29 males and 15 females, with a mean [SD] age of 13.5 [5.0] years) and 44 (22 males and 22 females, with a mean [SD] age 14.9 [4.2] years) age- and sex-matched controls were evaluated in this study. Each maxillary sinus was assessed 3-dimensionally, segmented, and its volume was calculated. Results: There were no statistically significant differences between the age and gender distributions of the groups. There was a statistically significant difference in the MSVs of the cleft (10996.78±3522.89 mm3) versus the noncleft side (10382.3±3416.2 mm3; P < .05)] but no significant difference between the MSVs of the right and left sides ( P > .05). In the intergroup comparison, the mean MSVs of the UCLP patients (10701.52±3369.33 mm3) were significantly smaller than those of the control group (16054.08 ± 5293.96 mm3; P < .001). Conclusions: The MSVs of the UCLP patients showed a statistically significant decrease compared to those of the controls ( P < .001). There was also a significant difference in the MSVs of the cleft and noncleft sides of the UCLP patients ( P < .05).

Latar belakang: suatu kasus impaksi gigi dapat menyebabkan maloklusi, dan kelainan oklusi akan semakin bertambah dengan bertambahnya usia. Impaksi gigi kaninus merupakan gigi kedua setelah gigi molar ketiga yang berfrekuensi tinggi untuk mengalami impaksi, persentasenya sekitar 12%-15% dari populasi. Gigi supernumerary adalah gigi tambahan/berlebih, sehingga jumlah gigi yang terbentuk dalam rahang lebih banyak dari jumlah normal. Terjadinya impaksi gigi kaninus dan supernumerary secara bersamaan jarang terjadi. Tujuan: Menambah wawasan du bidang bedah mulut minor, terutama dalam menangani suatu kasus impaksi gigi kaninus dan supernumerary untuk perawatan orthodonti. Kasus dan Penanganan: Dilaporkan seorang apsien, wanita, berusia 38 tahun yang baru menyadari kelainan maloklusinya dengan keluhan gigi depannya bertambah maju akibat adanya impaksi gigi kaninus dan impaksi gigi supernumerary. Pasien dikonsulkan dari Bagian Orthodonti ke Bagian Bedah Mulut untuk penanganan impaksi gigi kaninus dan supernumerary dengan kemungkinan untuk mempertahankan gigi kaninus memulai pembedahan. Dengan berbagai pertimbangan, penderita pada akhirnya menjalani operasi pengambilan gigi kaninus dan gigi supernumerary di Bagian Bedah Mulut RSGM Prof. Soedomo. Langkah-langkah diagnosis, operasi dan berbagai kemungkinan komplikasi juga turut disertakan di dalam pembahasan. Kesimpulan: Pengambilan gigi kaninus dan gigi supernumerary yang terpendam merupakan pilihan perawatan jika tidak memungkinkan untuk dilakukan exposure pada impaksi gigi kaninus pada maksila. Background: Impacted canines is the second most impacted tooth after third molar impaction, approximately 12%-15% of the population present with impacted canines. A supernumerary tooth is one that is additional to the normal series and can be found in almost any region of the dental arch. The incidence of an impacted canines as a sequent with a supernumerary tooth is very rare. Purpose: The aim of this case report is to add more information about a minor surgery due to canine and supernumerary tooth impaction for orthodontic treatment. Case and Management: We reported a case of a woman, 38 years old who have noticed a malocclution through the forwardness movement of her anterior teeth, due to the present of impacted canine and supernumerary. The patient consulted from orthodontic department to oral and maxillofacial department for further assessment, treatment and also the probability for surgical exposure of impacted canine. We have decided to do odontectomy for the impacted canine and supernumerary tooth as well at Oral and Maxillofacial department, Prof. Soedomo Hospital. The diagnosis process, exposure of impacted canine considerations are also discussed. Conclusion: the odontectomy for impacted canine and supernumerary teeth had performed as last options if there is impossible to do an exposure of an impacted canine.

Introduction Maxillary sinus disease is common and numerous disorders can affect this anatomical area. Abnormalities can be classified as: non-neoplastic, neoplastic benign, and neoplastic malignant. Objective Evaluate through CT the prevalence of diseases in maxillary sinuses, using the Radiology Department's database of a hospital in São Paulo city. Methods The sample consisted of 762 facial CT scans that we divided into three groups: Group A (12–19 years old); Group B (20–49 years old); Group C (above 50 years old); and male or female. We considered the following pathological processes: I - Mucoperiosteal Thickening; II - Chronic Sinusitis; III - Chronic Odontogenic Sinusitis; IV - Rhinosinusitis; V - Polypoid Lesions; VI - Bone Lesions; VII - Neoplasms; VIII - Antrolith; IX - Foreign Bodies; X - Oroantral Fistula. Results Our study found that 305 exams (40.02%) were normal and 457 exams (59.97%) were abnormal. We found the following disease frequencies: focal mucoperiosteal thickening (21.25%); polypoid lesions (10.76%); chronic sinusitis (7.48%); chronic odontogenic sinusitis (2.29%); neoplasms (2.03%); rhinosinusitis (1.77%); bone lesions, foreign bodies and oroantral fistula in 0.65%; 0.13% and 0.06% respectively. There was no significant difference between male and female, and Groups A, B, or C when relating the frequencies of abnormalities found. There was no significant difference between male and female and the age group for the side of the altered maxillary sinus. Conclusion We observed a high prevalence of sinus maxillary diseases. Mucoperiosteal thickening; acute, chronic, and odontogenic sinusitis; polypoid lesions and neoplasms have high prevalence in maxillary sinuses. Thus, facial CT exam was effective for the evaluation of diseases in maxillary sinuses.

Background Total knee arthroplasty is a challenging task in patients with severe varus deformity. In most of these patients, an extensive medial release is needed that may lead to instability. Medial epicondylar osteotomy may be a better substitute for complete medial collateral release. Materials and Methods Fourteen patients with bilateral knee osteoarthritis and severe varus deformity were enrolled in this study. In one side, the patients underwent medial epicondylar osteotomy for mediolateral imbalance if the only option was superficial medial collateral ligament (MCL) release. In contralateral side, the extensive medial release was performed and MCL was released either by pie-crusting technique or by subperiosteally release. The results of the two sides were compared. Patients were followed up for 12 months after the operation. Physical examination, clinical questionnaires, and radiography findings were recorded. Union of the osteotomies fragment and complications was evaluated. Results The mean varus angle before surgery was 21.6 ± 4.7 degrees, which was corrected to 8.6 ± 2.9 degrees after operation with an extensive medial release. The mean varus angle of contralateral side was 22.6 ± 1.7 degrees, which was corrected to 7.5 ± 2.3 degrees following medial femoral epicondyle osteotomy. There was no significant difference in varus correction (p = 0.1). Medial joint line opening in valgus stress test was 2.7 ± 0.4 mm in the osteotomized side and 3.5 ± 0.9 mm in contralateral side. Mean range of motion for the osteotomized side was 97.8 ± 4.3 degrees and 100.7 ± 2.7 degrees for contralateral side (p = 0.6). Nonunion occurred in a case in the osteotomized side and no medial instability was observed in medial release or osteotomies sides. No statistical difference was recorded based on clinical questionnaires (Oxford and WOMAC [Western Ontario and McMaster Universities Osteoarthritis Index] scores). Conclusion Medial epicondylar osteotomy is a safe technique with the well-controlled medial extensive release in the patients with severe varus deformity during total knee arthroplasty.

Abstract Background and aims: Maxillary sinuses are the largest of the paranasal sinuses known for variability in their dimensions. The maxillary sinus dimensions can be better ascertained in living by using computed tomography instead of plain radiography. This study was planned for highlighting the variations in the dimensions of the maxillary sinuses of population of Tamil Nadu region. The aims of the present study were to estimate dimensions of the maxillary sinuses on computed tomographic (CT) scan of the head of patients from Tamil Nadu and to compare the data gender wise and sidewise. Material and methods: Maximum width, height and depth of maxillary sinus of both sides were measured in CT - head images of 100 males and 100 females of 20-50 years of age in Tamil Nadu. Comparison of data between genders and sides by applying unpaired student "t" test was done. Results : The mean depth, height and width of both right and left maxillary sinuses were comparatively less in females than the males and the difference was found to be statistically significant ( P <.0001). On comparison between the sides of maxillary sinuses, the depth and the height of maxillary sinus did not show any significant difference in the measurements (p >.05), whereas the width of the left side (23.96 mm) was higher than that of the right side (23.69) and the difference was found to be statistically significant (P<.05). The combined average maxillary sinus dimensions (in mm) for both genders in the study population of Tamil Nadu are as follows: Right side depth: 33.71 ± 1.00; Left side depth : 33.65 ± 1.22; Right side height: 34.66 ± 2.71; Left side height: 34.74± 2.48; Right side width: 23.69 ± 0.78 and Left side width: 23.96 ± 0.86. Conclusion: The dimensions of maxillary sinuses in males were found to be larger than those of females and this difference was statistically significant. The average width of the maxillary sinuses on the left side is significantly more than that of right sided sinuses. Computed tomography measurements of maxillary sinuses may be useful in gender determination.

AbstractTo investigate the relation between the clinicopathological findings, and the survival of patients with malignant tumours of the maxillary sinus, and the tumour's biological parameters, we examined the expression of p53 and bcl-2 and the number of silver-stainable nucleolar organizer regions (AgNORs) in 23 paraffin-embedded specimens from primary tumours. Fifteen of 23 (65 per cent) maxillary tumours expressed p53 and two of 23 (nine per cent) tumours expressed the bcl-2 gene product. The mean number of AgNORs per nucleus was 5.2 ± 2.4. There was no relationship between the expression of p53 or bcl-2 and the patient's clinical course. In contrast, there was a statistically significant difference in the survival of patients with a high (>6) number of AgNORs and patients with a low (<6) number of AgNORs. These data suggest that the number of AgNORs may be useful in evaluating the prognosis of patients with malignant maxillary sinus tumours.
