Morphometric measurements of the internal acoustic meatus
Öz
Purpose: This study was aimed to determine the morphometry of internal acoustic meatus in healthy Turkish population aged between 18-60 years.
Materials and Methods: This study which was a retrospective study, was carried out from the 142 healthy adult subjects (59 females; 83 males) aged 18-60 years. Subjects had undergone routine test in the Radiology Department.
Results: The groups were divided into four groups according to age. The overall means of the measurements were: the internal acoustic meatus length 9.71 mm (R) and 9.92 mm (L); the internal acoustic meatus width 3.97 mm (R) and 3.95 mm (L); the internal acoustic meatus height 4.65 mm (R) and 4.66 mm (L) in females, respectively. The same dimensions were found 9.61 mm (R) and 9.87 mm (L); 4.18 mm (R) and 4.15 mm (L); 5.13 ±0.85 mm (R) and 5.13±0.90 mm (L) in males, respectively. Also, the ratio of IAM’width to height was calculated 0.860±0.125 and 0.825±0.137 in females and males in right side, respectively whereas in left side the corresponding value was 0.855±0.125 and 0.820±0.142 in females and males, respectively.
Conclusion: Knowledge of the normal dimensions of the internal acoustic meatus is more important for determination of the clinical and tumor processes.
