Objectives: This research is aimed to determine the wide frequency distribution of anteroposterior frontal sinus with lateral cephalometric radiographs based on age and sex in West Jakarta, which is centered on RSGM FKG Trisakti University.   Material and Methods: This research is using descriptive observational research design and the anteroposterior width measurement of the frontal sinus uses the Erturk measurement method. This study used 125 lateral cephalometric radiographs (40 males and 85 females) as samples which taken from a server at the Dental Radiology Installation, RSGM FKG Trisakti University. Results: The result showed that the smallest mean width of the anteroposterior frontal sinuses in males is at 7 years (5.4 mm) and the largest size is at 19 years (9.76 mm). Whereas the smallest mean width of anteroposterior frontal sinuses in females is at the age of 7 years (5.4 mm) and the largest size is at the age of 20 years (9.25 mm). The average width of anteroposterior frontal sinuses is 6.6 mm in males and 5.58 mm in females. Conclusion: Males have an average width of anteroposterior frontal sinuses that is larger than females and there are some decrease in size in some age groups. Variations in size can occur due to genetic and environmental factors.

The present study was aimed to evaluate the importance of combined use of frontal sinus dimensions and evaluating possible implications.The study was retrospective and intended to measure dimensions on 60 digital radiographs (PA Caldwell's View)of age group 20 to 50 years. The Institutional Ethical Committee approved the research protocol. Inclusion Criteria was taken as radiographs with good image quality and absence of any artefact. Radiographs of individuals with bilateral complete frontal sinus development were included while radiographs are exhibiting pathology like, e.g. mucous retention within the frontal sinus, aplasia(unilateral and bilateral) or rudimentary frontal sinus excluded from the study. Parameters measured were maximum height, width on both sides and symmetry of frontal sinus.Out of 60 radiographs five were excluded from the study (2 frontal sinus aplasia and 3 unilateral frontal sinuses). The final study involved 55 radiographs(N=55) which constituted 28 males and 27 females. The mean values of maximum height and width were obtained. Symmetry was calculated using width. There were significant differences in average width and height of frontal sinus of males and females.The results of the study favour the radiographic evaluation and frontal sinus dimensions for identification in forensics and also it is useful for the management of sinus-related ailments.

AbstractSinonasal malignant melanoma is rare and usually occurs in the nasal cavity. Presentation is often varied and occurs late in the natural history of the disease, resulting in a poor prognosis. A case is reported of a patient with malignant melanoma arising from the frontal sinus who presented with a forehead swelling and progressive confusion. A review of the literature on malignant melanoma in the nasal cavity and paranasal sinuses regarding its presentation, site of origin and principles of management is discussed.

Objective: Despite advances in technology and instrumentation, access to the lateral frontal sinus remains a challenge for surgeons. We sought to quantify the reach and applicability of the upper blepharoplasty approach (UBA) to the frontal sinus. Methods: Twelve cadaveric specimens were obtained for anatomic research and frontal sinuses divided into 3 zones. Zone 1 was defined as medial to the supraorbital neurovascular bundle (SON). The remaining orbit was then bisected to define zone 2 (centrally) and zone 3 (laterally). Twenty-four UBAs were performed followed by 12 modified endoscopic Lothrop procedures (MELP). The ability to instrument each wall of the frontal sinus was recorded for the MELP, UBA, and combined approach. Results: The UBA provided excellent access to the lateral frontal sinus in zones 2 and 3 (89% and 100%). The MELP provided poorer access in zone 3 (67%) but improved access in zone 1 (83%-100%). Access for zone 1 through the UBA was limited. The combined approach yielded 100% access to each frontal sinus boundary. Conclusion: The MELP in combination with the UBA/lateral trephination provides excellent access to each frontal sinus boundary. The UBA provides excellent access to the lateral frontal sinus but is limited medially by the SON.

Although intrusions of glass fragments into the frontal sinuses are not uncommon in traffic accidents, a case with a tooth in the frontal sinus has never been reported. We report a patient with traumatic inclusion of an incisor tooth in the contralateral frontal sinus. Radiographic investigations demonstrated the tooth in the frontal sinus though no skin damage was recognized on the upper face. The usefulness of CT scan in localizing the missing tooth after facial trauma and its route of entry into the contralateral frontal sinus is discussed.

Most of the studies of frontal sinus anatomy were completed 50 to 70 years ago. The information they provide is not necessarily relevant or helpful to the modem rhinologic surgeon who approaches the frontal sinus transnasally and endoscopically. We performed anatomical dissections of the outflow tract of 82 frontal sinuses in 41 cadaver heads to illustrate the various drainage patterns from the frontal sinus to the nose and to correlate these drainage sites with the distance and angle from the pyriform aperture. We found that the frontal sinus drained anterior to the uncinate process in 24 specimens (29.3%) with an average distance of 3.65 cm from the pyriform aperture and 58° from the nasal floor. The frontal sinus drained posterior to the uncinate process in 56 specimens (68.3%) with an average distance of 4.10 cm and 65 degrees from the nasal floor. In this latter group, most of the sinuses (51 specimens) drained into the ethmoid infundibulum. Two of the specimens had a hypoplastic frontal sinus with no outflow tract at all. These findings are different from those described in the early 20th century.

Absence of frontal sinus is usually associated with various syndromes such as craniosynostosis, osteodysplasia, down syndrome etc. Geographically, absence of frontal sinus is seen usually in areas with cold climate. This paper reports a case of 18-year old Indian woman suffering from bilateral absence of frontal sinuses which was non-syndromic in conjunction with unilateral mandibular hypoplasia. The paper also highlights the clinical significance of frontal sinus which was non-syndromic absence and its rarity in warm climate such as in South East Asian regions and the treatment options of unilateral mandibular hypoplasia.

Background: The mechanisms of testicular thermoregulation may influence the blood flow provided by the testicular artery, where the proper blood supply to the testicle is crucial for promotingspermatogenesis and reproductive function in bulls. The size and shape of the testicles are determined by genetic mechanisms and environmental effects. A better understanding of the relationships between the anatomical characteristics of the testicles and scrotum can support a better reproductive assessment. The purpose of the current study was to evaluate the testicular temperature of different scrotal shapes using infrared thermography in bulls.Materials, Methods & Results: We evaluated 132 Braford bulls with an average age of 24 months. The evaluation of breeding bull semen was performed prior to the beginning of the experiment. Then, animals were selected on the basis of the size of their testes, which was determined by dividing the average width by the average length. The scrotal circumference was measured with a millimeter tape positioned around the largest circumference. Testicular and ocular temperature measurements and analysis were conducted using an infrared thermal camera, Flir T440 with emissivity of 0.98 and thermal sensitivity of 0.05°C. Testicular scrotum temperature and testicular shape were analyzed with one-way ANOVA using Minitab 16, and values of P < 0.05 were considered statistically significant. We observed that 67.42% of testicle shapes were long-oval, and 32.58% were long-moderate. The testicular temperature was higher in bulls with the long-moderate shape compared to those with the long-oval shape (P < 0.05). The mean length was higher in long-moderate shaped testicles compared to those of the long-oval shape (P < 0.01). There was no significant differences in rectal and ocular temperatures or in scrotal circumference between bulls with long-moderate and long-oval shapes (P > 0.05). In addition, the mean width was lower in testicles of long-moderate shape compared to those of the long-oval scrotal format (P < 0.01).Discussion: The results obtained showed that Braford bulls with the long-moderate testicular shape have a higher testicular temperature to maintain proper thermoregulation. The present study demonstrated that IRT can be used to evaluate the testicular temperature in animals with different scrotal conformations. In this study, Braford bulls showed lower length and width values for animals having long-moderate (9.21 and 5.22, respectively) and long-oval formats (8.56 and 5.56, respectively). In contrast, previous reports examining Nellore bulls between the ages of 17-20 months found a predominance of the long oval shape followed by the long-moderate shape, which indicates a change in testicular shape as age progresses, resulting in a rounder testicular shape. Perhaps other factors, such as the external cremaster muscle and tunica dartos, cause the testicles to be retracted towards the body at lower temperatures while at high temperatures, relaxation occurs. The prevailing testicular shape in Braford animals with a mean age of 24 months was the long-moderate shape. Thus, testicles with a larger surface area will have lower temperatures because they can dissipate heat more easily than testicles with lower surface area. The results suggest that the long-moderate scrotum format may influence the testicular temperature in mature Braford bulls.

ABSTRACT: Cattle have extensive paranasal sinuses that are susceptible to disease, most commonly sinusitis. The sinuscopy can be used to evaluate these structures, although there are no descriptions of this region for endoscopic anatomy, especially regarding the trocar position and the most appropriate type of endoscope. This study aimed to standardize the surgical approaches to sinuscopy in cattle by comparing the use of three endoscopes. Four accesses by trephination (one hole for each of the maxillary and frontal sinuses) were made in eight heads of slaughtered cattle. Each hole was inspected with three endoscopes: a 10mm flexible colonoscope with up to 180º of angulation, a 10mm 0° laparoscope and a 4mm 30º arthroscope. It was observed that all regions of the maxillary sinus were better visualized with the 4mm endoscope, and the structures of this sinus were less well visualized with the 10mm laparoscope. The frontal sinus was difficult to evaluate due to the tortuosity of its bony projections, and the cranial portion was not observed by the proposed accesses. The caudal regions of the frontal sinus such as the nuchal diverticulum and the back of the orbit had the greatest number of structures visualized by the 4mm endoscope, followed by the colonoscope. The comparative analysis showed that the 4mm endoscope was most efficient and could be adapted to sinuscopy in cattle.
