Frontal nerv

Frontal nerv - oftalmik nervni eng katta tarmog'i ya'ni shoxi bo'lib, o'zi trigeminal nervning (CN V) bir tarmog'i. Peshona terisini, frontal sinusning shilliq qavatini va yuqori ko'z qovog'ining terisini innervatsiya qiladi.

Tuzilishi[tahrir | manbasini tahrirlash]

Frontal nerv ko'z nervining (V1) shoxchasi bo'lib, o'zi trigeminal nervning bir tarmog'i^[1]. Frontal nerv yuqori orbital yoriqga kirishdan oldin darhol shoxlanadi. Keyin lakrimal nerv va pastki oftalmik vena o'rtasida Zin halqasining superolateraliga o'tadi. Orbitaga kirgandan so'ng, tomning periosteum va levator palpebrae superioris o'rtasida oldinga qarab harakatlanadi. Orbita cho'qqisi o'rtasida u ikkita shoxchaga bo'linadi: supratroxlear nerv va supraorbital nerv.

Funksiyalar[tahrir | manbasini tahrirlash]

Frontal nervni ikkita shoxlari peshona terisini, frontal sinusni shilliq qavatini (havo sinusi) va yuqori ko'z qovog'ini terisini innervatsiya qilishni ta'minlaydi.

Frontal nerv kamdan-kam hollarda miyelin qobig'ini ta'sir qiladigan saraton bo'lgan schwannomadan ta'sirlanishi mumkin^[2]^[3]. Bu yuqori orbital yoriq va supraorbital foramen yoki supraorbital kentik o'rtasida bo'lishi mumkin^[2]. Frontal suyakning qo'shni orbital qismiga zarar etkazishi mumkin^[2]. Saraton darajasini aniqlash uchun kompyuter tomografiyasi yoki magnit-rezonans tomografiya ishlatilishi mumkin^[2]^[3]. Tashxisni tasdiqlash uchun biopsiya olinishi mumkin.^[3] Shvannomani olib tashlash uchun jarrohlikdan foydalanish mumkin^[3].
