        <p>Yuz-jag‘ sohasi travmalari zamonaviy tibbiyotda dolzarb muammolardan biri bo‘lib, ularning oqibatida yuzaga keladigan asoratlar stomatologiya va jag‘-yuz jarrohligi amaliyotida murakkab patologik jarayonlarni shakllantiradi. Ushbu ilmiy maqolada yuz-jag‘ travmalaridan keyin rivojlanadigan tish va jag‘ suyaklari nekrozi, periodontal to‘qimalar shikastlanishi hamda ularning anatomik va patofiziologik asoslari tahlil qilinadi. Travmatik omillar ta‘sirida yuz-jag‘ sohasini qon bilan ta‘minlanishi buzilishi, suyak va yumshoq to‘qimalarda trofik yetishmovchilik yuzaga kelishi nekrotik jarayonlarning rivojlanishiga zamin yaratadi. Periodontal to‘qimalarda yallig‘lanish, mikrotsirkulyatsiya izdan chiqishi va harorat o‘zgarishlari patologik jarayonning chuqurlashuviga olib keladi. Maqolada yuz-jag‘ travmalarining turlari, sinish mexanizmlari, davolash jarayonida uchraydigan asoratlar va ularning statistik dolzarbligi ilmiy manbalar asosida yoritilgan. Ushbu tahliliy ish yuz-jag‘ travmalarining uzoq muddatli oqibatlarini tushunishda nazariy asos bo‘lib xizmat qiladi. Kalit so‘lar: yuz-jag‘ travmasi, jag‘ nekrozi, periodontal jarohat, sinish, mikrotsirkulyatsiya, yallig‘lanish, harorat, osteonekroz, travmatik omil, qon ta‘minoti, suyak rezobsiyasi.

        <p>Trauma of the maxillofacial region is one of the pressing problems of modern medicine, and the complications arising from it form complex pathological processes in the practice of dentistry and maxillofacial surgery. This scientific article analyses the necrosis of the teeth and jaw bones and the damage to the periodontal tissues that develop after maxillofacial trauma, together with their anatomical and pathophysiological foundations. Under the influence of traumatic factors, the disruption of the blood supply to the maxillofacial region and the emergence of trophic insufficiency in bone and soft tissues create the basis for the development of necrotic processes. Inflammation of the periodontal tissues, disturbance of microcirculation and temperature changes lead to the deepening of the pathological process. The article describes, on the basis of scientific sources, the types of maxillofacial trauma, the mechanisms of fractures, the complications encountered during treatment and their statistical relevance. This analytical work serves as a theoretical foundation for understanding the long-term consequences of maxillofacial trauma.</p>

        <p>Челюстно-лицевая травма является одной из актуальных проблем современной медицины, а возникающие в результате нее осложнения формируют сложные патологические процессы в практике стоматологии и челюстно-лицевой хирургии. В данной научной статье анализируются некроз зубов и челюстных костей, повреждение пародонтальных тканей и их анатомические и патофизиологические основы после челюстно-лицевой травмы. Под воздействием травматических факторов нарушение кровоснабжения челюстно-лицевой области, трофическая недостаточность костной и мягкой ткани создают основу для развития некротических процессов. Воспаление, нарушение микроциркуляции и температурные изменения в пародонтальных тканях приводят к углублению патологического процесса. В статье рассматриваются виды челюстно-лицевой травмы, механизмы переломов, осложнения при лечении и их статистическая значимость на основе научных источников. Данная аналитическая работа служит теоретической основой для понимания долгосрочных последствий челюстно-лицевой травмы.</p>
