J34: Other disorders of nose and nasal sinuses

Disorders of the nose and nasal sinuses, classified under ICD-10 group J34, encompass a variety of conditions that impact the structure and function of the nose and adjacent sinus cavities. These conditions can be due to malformations of the nasal structure, infections, inflammation, or the growth of abnormal tissues such as polyps. Common symptoms across this group of disorders include nasal obstruction or congestion, runny nose, sinus pressure or pain, changes in smell and taste, and, in some cases, difficulty breathing. These symptoms can be intermittent or persistent, and their severity can range from mild to severe. The progression of these disorders will depend on their specific cause. While some conditions may stay relatively stable or resolve on their own, others may worsen over time or lead to complications if left untreated. Despite the varied causes and outcomes, all disorders within this group affect the upper respiratory system, particularly the nasal passages and sinus cavities.
