Amaç: Bu radioanatomik çalışmada, optik sinir cerrahisi açısından önemli bir referans noktası olması nedeni ile optik strut’ın morfometrik özellikleri ile ilgili veri elde edilmesi amaçlanmıştır. Materyal-Metot: Tıp Fakültesi Anatomi Anabilim Dalı envanterinde bulunan 7 adet erişkin insan kuru kafatası bu çalışmaya dahil edildi. Direkt anatomik ölçümler dijital kumpas ve radyolojik ölçümler bilgisayarlı tomografi yardımı ile elde edildi. Prekiyazmatik sulkusa göre optik strut’ın konumu değerlendirildi. Bulgular: Direkt anatomik ölçümlerde optik strut’ın uzunluğu ve genişliği 4.53±0.74 mm ve 4.83±1.34 mm olarak bulundu. Bilgisayarlı tomografide ise optik strut’ın uzunluk ve genişliği 4.13±1.27 mm ve 4.31±0.82 mm olarak tespit edildi. Direkt anatomik ölçüm ve bilgisayarlı tomografide iki strut arası mesafe 16.83±2.56 mm ve 15.91±1.81 mm olarak bulundu. Bilgisayarlı tomografi ve direkt anatomik değerlendirmede optik strut’ın 4 kuru kafada sulkal, 2 kuru kafada postsulkal ve 1 kuru kafada asimetrik olduğu belirlendi. Sonuç: Optik strut’ın cerrahlar açısından bir referans noktası olması ve anteriyor klinoid proses rezeksiyonu sırasında hasarlanabileceği dikkate alındığında, sayısal verilerimiz optik sinir çevresinde yapılan cerrahi müdahaleler sırasında faydalı olabilir.

The work aimed to compare fetal and adult tympanic membrane (TM) sizes for understanding dimensional development from intrauterine life to adulthood. Fifty-six temporal bones (18 fetuses, 10 elderly adults, half male and half female in each group) were included in this study. Using a digital image software, the TM height, width and area were measured. The mean area, height and width of the TM in adults were found as 58.84 ± 22.01 mm2, 9.06 ± 1.33 mm, and 8.10 ± 1.43 mm, respectively. Moreover, the mean area, height and width of the TM in fetuses were measured as 47.62 ± 12.57 mm2, 8.22 ± 1.12 mm, and 7.25 ± 1.15 mm, respectively. The TM dimensions were increasing in fetuses between 20–32 weeks of gestation. However, the TM dimension was statistically similar at the 7th month, the 8th month and adult periods. The TM height was greater than its width in fetuses and adults. The calculated regression equations of the TM parameters in fetuses may be used to estimate its size. The TM size did not change from the 7th gestational month, and thus the membrane reached adult diameter in fetal life. The TM height and width showed a very wide range; therefore, we thought that the 12 mm (the height) × 10 mm (the width) graft might be ideal dimension during the repair of the TM perforations.

The main objective of the study was to investigate the morphometric properties of the stapedial tendon (ST) for pediatric otosurgeons and anatomists. The present study was placed on 15 fetuses (8 females, 7 males) aged from 20 to 30 weeks of gestation (at mean, 24.27 ± 3.24 weeks) using the collection of the Anatomy Department of Medicine Faculty, Mersin University. All measurements were obtained with a digital image analysis software. In terms of male/female or right/left comparisons, no statistically significant difference was found in relation with the numerical data of ST. The surface area, length, and width of ST were detected as follows: 0.61 ± 0.15 mm2, 1.27 ± 0.30 mm, and 0.45 ± 0.08 mm, respectively. The absence of ST was observed in two fetuses with and without severe malformations. In another fetus with cleft lip and polydactyly, multiple abnormalities were bilaterally identified in the middle ear: (1) the absence of the incudostapedial joint and (2) the presence of an abnormal tissue attaching to the stapes. The abnormal tissue was determined to be irregular dense connective tissue using light microscope and electron microscope. Our findings showed that ST did not proportionally grow according to increasing gestational weeks. In the light of the numerical data, we thought that similar to stapes, ST attains the adult size in the fetal period. As ST anomalies may accompany severe malformations (e.g., cleft lip, polydactyly or syndactyly) that can be easily detected on observation by clinicians, we suggest that the detailed examination of middle ear in newborns should be taken into account for early diagnosis of conductive hearing loss to prevent any management delays.

DergiPark: 439218 tmsj Aims: The aim of this study is to present a case of an infection in the oral cavity due to tongue piercing perforatedinto the floor of the mouth, thus to raise concern over the increasing popularity of tongue piercing in spite of its risksincluding perforation in the oral cavity and oral ulcers.Case Report: A sixteen-year-old female patient presented to the clinic with lesions and extreme pain in her oralcavity. The thorough examination showed displacement of the piercing through the tongue, causing a perforation ofthe floor of the mouth. The piercing was surgically removed. The ulcers were treated with medication. The patientwas advised to get professional help and was instructed to pay close attention to oral hygiene in case of reiterateddemand for tongue piercing.Conclusion: It is important to ensure that piercing is inserted by a specialist under sterile conditions to preventcomplications. If a surgical operation is needed to treat the complications occurred, the clinicians must be aware ofthe critical veins and nerves that are located in the oral cavity and they should be very careful not to cause any harmduring the operation.
