RESUMEN
Background: The aim is to know gender wise development and morphological variation of the frontal sinus in the pediatric age group of Gurugram district of Haryana. The development and pneumatisation of the frontal sinus is the predictor of skeletal growth pattern. The craniofacial structures grow proportionately with the normal development of the body structures. Methods: In this prospective study, a total of 36 subjects were studied. The study was conducted in the Department of Radiodiagnosis of SGT Medical College, Budhera (Gurugram) Haryana from January 2019 to March 2019. This included 12 females and 24 males falling in the age group of 8-18 years. The frontal sinuses were evaluated on various morphological features. Plain X-Ray of paranasal sinus was evaluated by Caldwell’s view. The sinuses were evaluated for width, height, number of scallops, septations and supraorbital cells. Results: Average width and height of left frontal sinuses were 23.8 mm with the range of 5.5 – 43 mm and 28.4 mm with the range of 13-45 mm respectively. Average width and height of right frontal sinuses were 20.4 mm with the range of 9.8 – 39 mm and 20 mm with the range of 13-38 mm respectively. The average number of scalloping on right and left were 1.9 and 2.19 respectively. The septations were noticed in 13 (36.11%) on left and in 16 (44.44%) on right side. Supraorbital cells were found in 16 (44.44%) on left side and 17 (47.22%) on right side. Conclusion: There is a lot of variation in the appearance and development of the frontal sinus in pediatric age group. The dimensions had been found smaller on right side as compared to left side. Scalloping and supraorbital cells had been found more on right side than on the left side. Septations were more on left side as compared to right side.
RESUMEN
PURPOSE: The purpose of this study was to evaluate distalizing effects from the Pendulum appliance on vertical component of craniofacial structures. MATERIALS AND METHODS: 20 Patients who visited for orthodontic treatments are assigned to two groups. Group I, SN-MP > 37 degrees are showing hyperdivergent pattern. Group II, 29 < SN-MP < 37 degrees are showing mesocephalic pattern. Each group are consisted of 10 people. RESULTS AND CONCLUSIONS: Differences between skeletal classifications result in significant differences at labioversion of lower incisors and distalized amount, which is larger at Group I (P <.05). Group II has only shown significant distalized molars (P < .05). Labioversion of lower incisors has not shown significant change. Skeletal anchorage-assisted Pendulum appliance doesn't deteriorate vertical component nor significantly improve.
