Nasal Polyps

Özet: Nasal polyps are benign mucosal growths associated with persistent inflammation of the nose and sinuses. They may occur alongside chronic rhinosinusitis, asthma or aspirin sensitivity, while individual patterns vary. Assessment may include examination, nasal endoscopy and, when clinically indicated, imaging or tissue analysis. Medical or surgical management depends on physician evaluation, and outcomes vary according to the underlying inflammatory process.

Nasal polyps are benign, soft growths arising from the mucosal lining of the nose and sinuses. They may contribute to persistent nasal obstruction, reduced smell and related complaints, but symptoms alone cannot confirm their presence or distinguish them from other conditions. Diagnosis and management therefore require an individual clinical assessment.

What Are Nasal Polyps?

A nasal polyp is a benign, soft tissue growth that develops from the lining of the nose or paranasal sinuses. Polyps may appear singly or in groups and can affect one or both sides. Their appearance can resemble a peeled grape, but visual resemblance alone is not sufficient for diagnosis.

Structurally, polyps contain swollen tissue associated with inflammation. They behave differently from many solid tumours, although this distinction cannot be established safely through symptoms or home observation. A lesion with an unusual appearance or clinical course may require further examination and, when the physician considers it appropriate, histopathological analysis (laboratory examination of tissue).

Who Is at Risk of Nasal Polyps?

Nasal polyps may develop in several inflammatory clinical settings and do not have one universal cause. Chronic rhinosinusitis, asthma, aspirin or NSAID sensitivity, allergy-related inflammation and certain underlying disorders may be considered during assessment. Having one of these conditions does not by itself establish that polyps are present.

Conditions and backgrounds a physician may evaluate include:

• Chronic rhinosinusitis: Nasal polyps may occur as part of chronic rhinosinusitis with nasal polyps, abbreviated as CRSwNP.
• Asthma: Asthma and nasal polyps may coexist, but their relationship and clinical importance differ among individuals.
• Aspirin or NSAID sensitivity: Asthma, recurrent nasal polyps and reactions to aspirin or related medicines can occur together in aspirin-exacerbated respiratory disease, also known as Samter’s triad.
• Allergic background: Allergy may contribute to mucosal inflammation in some people, but an allergy history or test result alone does not explain every case.
• Eosinophilic inflammation: The physician may consider this inflammatory pattern alongside symptoms, examination findings and other clinical information.
• Cystic fibrosis: In children with nasal polyps, the possibility of an underlying condition may form part of the physician’s broader evaluation.

These associations describe possibilities rather than a self-diagnosis checklist. The same background can produce different findings in different people, while similar nasal complaints can occur without polyps.

What Are the Symptoms of Nasal Polyps?

Nasal polyps may be associated with persistent obstruction, reduced smell, postnasal drainage and facial pressure, although none of these complaints is specific to polyps. Symptoms can develop gradually and may overlap with inflammatory, allergic or structural nasal conditions. A physician distinguishes among these possibilities through history and examination rather than symptoms alone.

Complaints that may be discussed during the consultation include:

• Persistent or gradually increasing nasal obstruction
• Reduced smell (hyposmia) or loss of smell (anosmia)
• Food seeming less flavourful
• Postnasal drip and frequent throat clearing
• Fullness or pressure in the face or forehead
• Headache
• Mouth breathing during sleep
• Snoring or a nasal-sounding voice
• A sensation of fullness or tissue inside the nose

Keeping a simple record of when complaints occur, whether they affect one or both sides and which medicines are already being used can help prepare for the examination. Such observations are not a screening test or diagnostic measurement.

If symptoms are severe or rapidly worsening, a healthcare facility should be contacted without delay.

How Are Nasal Polyps Diagnosed?

Diagnosis combines the person’s history with a direct examination of the nasal cavity. Nasal endoscopy (examination with a thin camera) can help the physician evaluate the location and extent of tissue changes. Imaging, smell assessment, laboratory tests or histopathology may be added when their results could clarify diagnosis or management.

The assessment may include:

1. Clinical history and anterior examination: The physician asks about obstruction, smell changes, asthma, medication reactions, allergy-related complaints and previous nasal or sinus procedures.
2. Nasal endoscopy: Endoscopic examination provides a closer view of the nasal passages, middle meatus and accessible sinus openings.
3. Paranasal sinus CT: Computed tomography may be requested when more detailed anatomical information is needed, particularly during evaluation for possible surgery.
4. Additional assessment: Smell testing, allergy evaluation, eosinophil assessment or other tests may be considered according to the clinical context.
5. Histopathology: Tissue removed or sampled may be sent for laboratory examination when the physician considers this necessary to distinguish it from other conditions.

No single symptom or home observation can replace this process. The need for CT or tissue analysis is determined individually rather than applied as an absolute rule to every person.

How Are Nasal Polyps Treated?

Management aims to address inflammation, nasal complaints and the possibility of recurrence. Depending on examination findings and the person’s wider health, a physician may consider prescription medicines, supportive care, surgery or targeted therapy. These options are not interchangeable, and their sequence, expected benefit and risks require individual medical assessment.

Criterion	Medical management	Surgical management (FESS)
Clinical role	May be considered to control inflammation and symptoms	May be considered when symptoms and findings remain inadequately controlled
What it involves	Prescription nasal corticosteroids, selected systemic medicines or supportive measures	Endoscopic removal of polyp tissue and treatment of obstructed sinus pathways
Potential benefit	Polyps and associated complaints may decrease	Nasal airflow, drainage and access for topical medicines may improve
Limitations and risks	Effects and adverse reactions vary; prescription changes require physician guidance	Bleeding, infection, tissue injury, anaesthesia-related complications and recurrence can occur
Continuing care	Use and monitoring follow the individual prescription	Ongoing medical care may still be needed after surgery

Medical treatment

Intranasal corticosteroid sprays such as mometasone, fluticasone or budesonide may be prescribed to control inflammation and reduce polyp-related complaints. The response and timing vary according to the medicine, technique, disease pattern and individual. Oral corticosteroids may be considered selectively after the physician weighs potential benefits against systemic adverse effects.

Saline rinses may form part of supportive care, while antihistamines or antibiotics are considered only when the clinical assessment identifies an appropriate reason. This information is not an instruction to start, stop or change any medicine. Prescription sprays, oral corticosteroids and other prescribed treatments must not be stopped, reduced or altered without consulting the prescribing physician.

Surgery: endoscopic sinus surgery (FESS)

Functional endoscopic sinus surgery (FESS) may be considered when medical management does not provide adequate control and clinical findings support an operation. The surgeon works through the nostrils with endoscopic guidance to remove selected polyp tissue and address obstructed sinus pathways. The exact extent of surgery depends on the person’s anatomy and disease pattern.

An external skin incision may not be required for the endoscopic approach, but this does not make the procedure risk-free. Bleeding, infection, injury to nearby structures, anaesthesia-related complications and recurrence are among the matters considered during informed consent. Preservation of healthy tissue is an operative aim, but the amount and type of tissue treated are determined by surgical findings.

Septoplasty or turbinate surgery may sometimes be considered during the same anaesthetic session if a separate structural indication exists. Combining procedures is not automatically appropriate; each component requires its own clinical rationale and risk assessment.

Recurrence and continuing care

Nasal polyps can recur because the inflammatory background may persist after either medical or surgical treatment. Surgery removes or reduces existing tissue but does not guarantee that future inflammatory growth will be prevented. The course varies according to the underlying condition, accompanying diseases, treatment response and individual clinical factors.

A physician may prescribe continuing topical treatment, supportive care and follow-up examinations. Asthma, allergy-related disease or aspirin sensitivity may also require coordinated assessment. Prescribed treatment must not be stopped, reduced or changed without consulting the treating physician.

Biologic therapy in selected cases

Targeted biologic medicines may be considered for selected patients with difficult-to-control or recurrent disease, including some people who also have asthma. These prescription treatments affect particular inflammatory pathways and are not suitable for everyone. Eligibility, potential benefit, possible adverse effects and monitoring requirements are assessed individually by the relevant physicians.

Relationship With Sinusitis and Loss of Smell

Nasal polyps may occur within chronic sinusitis and can coexist with inflammation around the sinus openings. Obstruction and mucosal swelling may affect ventilation, drainage and the passage of air toward the smell region. The relative contribution of polyps, inflammation and other factors differs from one person to another.

Reduced smell can occur when airflow to the olfactory region is limited or when inflammation affects smell function. Treatment may improve smell in some individuals, but the degree and durability of change cannot be guaranteed. The course depends on the underlying inflammatory process, previous disease history and individual response.

Sinus complaints and smell loss do not independently prove that nasal polyps are present. Their combined assessment may include history, endoscopy and other examinations selected by the physician.

How It Differs From Structural Nose Surgery

Nasal polyp surgery and structural nasal surgery have different primary objectives. Polyp surgery addresses inflammatory tissue and sinus pathways, whereas rhinoplasty changes the bone or cartilage framework for structural or aesthetic reasons. Although both involve the nose, one procedure does not automatically substitute for or require the other.

Point of comparison	Nasal polyp surgery	Structural nose surgery
Main clinical focus	Inflammatory tissue and sinus pathways	Bone, cartilage and external or internal nasal framework
Assessment basis	Symptoms, endoscopy, imaging when indicated and inflammatory context	Structural examination, functional concerns and individual objectives
Technique	Commonly performed with endoscopic access through the nostrils	Technique varies according to the structure being addressed
Expected outcome	Symptom control may improve, but recurrence remains possible	Structural change may be achieved, but functional and aesthetic outcomes vary
Risk discussion	Includes surgical, anaesthetic and recurrence-related considerations	Includes surgical, anaesthetic, functional and appearance-related considerations

A person may have both inflammatory and structural findings. In that situation, the physician evaluates each problem separately before deciding whether procedures should be performed independently or during the same session. Neither approach offers a guaranteed result.

International Patients

For a patient who lives outside Türkiye, previous examination notes, imaging and medication history may provide useful background information. However, shared records or remote communication do not replace an in-person examination. Diagnosis, suitability for treatment and informed consent depend on direct physician assessment and review of the individual clinical situation.

Continuity of care also requires consideration because nasal polyp disease may need prescription management and follow-up beyond a single encounter. Any plan should account for access to the prescribing physician, postoperative assessment if surgery is performed and coordination with healthcare professionals where the person lives. Prescription medicines must not be changed without physician guidance.

Travel or accommodation arrangements should not determine whether a medical or surgical intervention is appropriate. Clinical decisions are based on examination findings, medical history, individual risks and informed consent.

The following answers address common decision-making questions without providing a self-diagnosis or personal treatment plan. Nasal symptoms overlap across inflammatory, allergic and structural conditions, so their meaning depends on examination findings. Medication suitability, the need for imaging and possible surgery must therefore be decided through an individual physician assessment.
