Pediatrik Larinks Hastalıkları
Özet
Pediatrik larinks hastalıkları, çocuk hava yolunun anatomik ve fizyolojik özellikleri nedeniyle kulak burun boğaz pratiğinde özel önem taşıyan bir hasta grubunu oluşturur. Çocuklarda larinks daha dar, daha yüksek yerleşimli ve nöromüsküler kontrol açısından daha immatür olduğundan, minimal patolojiler bile ciddi hava yolu obstrüksiyonuna yol açabilir. Bu nedenle pediatrik larinks hastalıklarının erken tanı ve uygun tedavi ile yönetilmesi hayati önem taşır. Bu bölümde pediatrik larinksin gelişimsel anatomisi ve fizyolojisi ayrıntılı olarak ele alınmakta, ardından pediatrik hastada klinik değerlendirme basamakları açıklanmaktadır. Stridor, disfoni ve beslenme problemleri gibi temel semptomların tanısal değeri vurgulanmakta; fleksibl nazofaringolaringoskopi ve direkt laringoskopi gibi endoskopik yöntemlerin tanıdaki rolü tartışılmaktadır. Konjenital patolojiler arasında en sık görülen neden olan laringomalazi, vokal kord paralizileri, subglottik stenoz, laringeal web ve subglottik hemanjiyom ayrıntılı olarak incelenmiştir. Ayrıca enfeksiyöz ve inflamatuvar hastalıklar kapsamında krup, epiglottit ve bakteriyel trakeit gibi akut üst hava yolu obstrüksiyonu nedenleri ele alınmıştır. Rekürren respiratuvar papillomatozis başta olmak üzere proliferatif lezyonlar ile pediatrik disfoni ve vokal kord nodülleri gibi fonksiyonel ses bozuklukları da değerlendirilmiştir. Son olarak prematüre bebekler, sendromik çocuklar ve nörolojik hastalığı olan hastalar gibi özel klinik durumlar tartışılmıştır. Pediatrik larinks hastalıklarının yönetiminde multidisipliner yaklaşım, erken tanı ve bireyselleştirilmiş tedavi stratejileri temel prensiplerdir.
Pediatric laryngeal disorders represent a clinically significant group of conditions in otolaryngology due to the unique anatomical and physiological characteristics of the pediatric airway. In children, the larynx is narrower, positioned more cranially, and functionally immature compared with adults; therefore, even minimal pathological changes may rapidly lead to significant airway obstruction. Early recognition and appropriate management are therefore critical for preventing morbidity and mortality. This chapter reviews the developmental anatomy and physiology of the pediatric larynx and outlines the principles of clinical evaluation in pediatric patients. Key presenting symptoms such as stridor, dysphonia, and feeding difficulties are discussed with emphasis on their diagnostic value. Endoscopic assessment, including flexible nasopharyngolaryngoscopy and direct laryngoscopy, plays a central role in diagnosis and treatment planning.
Common congenital laryngeal disorders such as laryngomalacia, vocal cord paralysis, subglottic stenosis, laryngeal webs, and subglottic hemangioma are discussed. Infectious and inflammatory causes of upper airway obstruction, including viral laryngotracheitis (croup), epiglottitis, and bacterial tracheitis, are also reviewed. In addition, proliferative lesions such as recurrent respiratory papillomatosis and functional voice disorders including pediatric dysphonia and vocal cord nodules are addressed. Special clinical situations such as premature infants, syndromic children, and patients with neurological disorders are also considered. Effective management requires early diagnosis, systematic evaluation, and a multidisciplinary approach aimed at maintaining airway safety while preserving voice and swallowing functions.
