Overview

Chronic Rhinosinusitis
Chronic rhinosinusitis is long-lasting inflammation of the nose and sinuses that persists for weeks or months and may repeatedly return. Common symptoms include nasal blockage, facial pressure or pain, reduced sense of smell, nasal discharge, postnasal drainage, and cough. Nasal polyps, allergies, infection, structural problems, and other inflammatory conditions can contribute to persistent symptoms.
Anal Fistula
An anal fistula is an abnormal tunnel that develops between the inside of the anus or rectum and the skin near the anus. It often develops after an infection or abscess in an anal gland. Symptoms may include persistent drainage, pain, swelling, irritation, or recurrent abscesses around the anus.

Diagnosis

Chronic Rhinosinusitis
Diagnosis is based on persistent nasal and sinus symptoms together with examination of the nose and surrounding structures. Nasal endoscopy may allow direct examination of the nasal passages and sinus openings. CT imaging of the sinuses may be used when symptoms persist, complications are suspected, or surgery is being considered. Allergy testing or other investigations may be appropriate when an underlying condition is suspected.
Anal Fistula
An anal fistula is diagnosed through a medical history and examination of the anus and surrounding skin. The healthcare professional may look for an external opening, drainage, swelling, or tenderness. A digital rectal examination may help identify the tract. Imaging such as MRI or ultrasound may be used when the fistula is complex, recurrent, or difficult to identify during examination.

Prevention

Chronic Rhinosinusitis
There is no guaranteed way to prevent chronic rhinosinusitis, but controlling contributing conditions may reduce symptoms and recurrence. Managing allergies and asthma, avoiding cigarette smoke and other nasal irritants, practicing good hand hygiene, and treating respiratory infections appropriately can help. Adequate hydration and following prescribed nasal treatments may support normal nasal and sinus function. Persistent symptoms should be evaluated rather than repeatedly self-treated.
Anal Fistula
Preventing anal fistula mainly involves reducing the risk of anal abscesses and treating infections promptly. People with inflammatory bowel disease should follow appropriate medical treatment and monitoring. Persistent pain, swelling, drainage, or recurrent abscesses around the anus should be evaluated by a healthcare professional rather than left untreated.

Risk Factors

Chronic Rhinosinusitis
Risk factors include nasal polyps, allergies, asthma, repeated respiratory infections, structural abnormalities of the nose or sinuses, exposure to cigarette smoke and other irritants, and certain inflammatory disorders. Problems with normal sinus drainage can promote persistent inflammation. Some people have a greater susceptibility because of underlying immune or respiratory conditions.
Anal Fistula
Risk factors include a previous anal abscess, inflammatory bowel disease such as Crohn disease, recurrent infections in the anal region, previous anal or rectal surgery, and conditions that interfere with normal healing or immunity. A history of an anal fistula also increases the likelihood of recurrence.
