It seems like there's an extra piece of tissue in the nostril.

Under normal circumstances, the sensation of an extra piece of tissue in the nostril may be related to conditions such as sinusitis, allergic rhinitis with inferior turbinate hypertrophy, nasal vestibular cysts, or nasal polyps. Patients can improve symptoms through medication or surgical treatment. A detailed analysis is as follows:

1. Sinusitis

Sinusitis is usually caused by upper respiratory tract infections. Frequent exposure to allergens such as pollen or perfume can also trigger sinusitis. After onset, patients typically experience symptoms including fever, nasal congestion, runny nose, and headache. Due to repeated inflammatory stimulation within the nasal cavity, a fleshy mass may appear in the nostril. Under medical guidance, patients may use medications such as budesonide inhalation aerosol or mometasone furoate nasal spray.

2. Allergic Rhinitis

This condition is typically caused by an allergic reaction leading to inflammation of the nasal mucosa. As the disease progresses, it may result in the appearance of excess tissue inside the nose. Therefore, patients are advised to follow medical instructions for timely drug treatment, such as loratadine tablets or cetirizine hydrochloride tablets.

3. Inferior Turbinate Hypertrophy

Inferior turbinate hypertrophy is usually caused by long-term stimulation from chronic inflammation, resulting in thickening and overgrowth of the mucosal layer and bone of the inferior turbinate. This leads to nasal obstruction, accompanied by symptoms such as runny nose, tinnitus, headache, and reduced sense of smell. Patients may use medications such as mometasone furoate nasal spray or naphazoline hydrochloride nasal drops as directed by a physician.

4. Nasal Vestibular Cyst

A nasal vestibular cyst refers to a cystic mass located beneath the skin of the nasal vestibule, anterior and lateral to the pyriform aperture, in the soft tissue in front of the maxillary alveolar process. It presents as a localized spherical bulge and clinically manifests as nasal congestion and a feeling of nasal fullness. Patients may undergo surgical treatment under medical supervision, such as excision of the nasal vestibular cyst or sublabial groove resection.

5. Nasal Polyps

Nasal polyps are benign growths formed when mucosal tissue abnormally proliferates and protrudes into the nasal cavity from the nasal passages. Symptoms include nasal blockage, increased nasal discharge, and facial pressure or pain. Surgical intervention, such as endoscopic nasal polyp removal, may be performed with medical guidance.

In addition to the common causes listed above, this condition may also be associated with deviated nasal septum, nasal hemangioma, or nasal tumors. If patients experience other discomforts, they should promptly seek medical attention at a hospital for diagnosis and treatment.
