Do the Angle and Length of the Eustachian Tube Affect the Success Rate of Pediatric Cartilage Type 1 Tympanoplasty

摘要: OBJECTIVES To investigate the relationships between angle and length of Eustachian tube (ET) (the ETa ETl) success rates pediatric type 1 tympanoplasty. STUDY DESIGN A retrospective clinical chart review. METHODS In total, 51 children (31 females 20 males; average age, 11.92 ± 3.46 years; age range: 7-18 years) who underwent cartilage tympanoplasty were included. Demographics anatomical outcomes recorded. The patients divided into 2 groups in terms success. group A, all had intact grafts without perforation, retraction, or lateralization, a dry ear, at 6 months postoperatively. B, reperforation tympanic membrane was evident ETl values each measured on computed tomography images using multiplanar reconstruction technique, compared. RESULTS diseased ears males were, respectively, 26.60 ± 6.42° 23.29 ± 6.51°, compared to 27.25 ± 5.23° 23.32 ± 4.61° for normal male female ears, respectively. 26.46 ± 6.82° 22.95 ± 7.50° females. 26.85 ± 6.12° 23.90 ± 4.45° mean 41.0 mm (29.6-45.3 mm) 37.9 mm (32.0-44.5 mm) 40.5 mm (30.5-47.1 mm) 38.0 mm (32.8-45.0 mm) value did not differ males, but higher than (P = 0.020 P   0.05). No difference either group, apparent (both P > 0.05). CONCLUSIONS Neither nor affected rate Further studies with larger numbers are needed compare after placement various graft types effects features ET
