Introduction
Maxillary sinusitis is an inflammation of the nasal sinus mucosa, which causes various discomforts during episodes. Common symptoms include nasal congestion, purulent nasal discharge, facial pain or tenderness, reduced sense of smell, and headache. Nasal congestion is a frequent symptom of maxillary sinusitis, typically presenting as unilateral or bilateral blockage of the nasal passages, resulting in impaired breathing. This symptom may be particularly noticeable upon waking in the morning and tends to worsen as the inflammation intensifies.
Maxillary sinusitis is an inflammation of the nasal sinus mucosa, which causes various discomforts during an episode. Common symptoms include nasal congestion, purulent nasal discharge, facial pain or tenderness, reduced sense of smell, and headaches. A detailed analysis is as follows:
1. Nasal congestion: This is a common symptom of maxillary sinusitis, often presenting as unilateral or bilateral nasal blockage, leading to difficulty breathing. Symptoms may be more pronounced upon waking and worsen as the inflammation progresses. Severe congestion can disrupt normal sleep and breathing.
2. Purulent nasal discharge: Patients may experience thick, mucopurulent, or purulent secretions from the nasal cavity, typically yellow or yellow-green in color. The discharge is often abundant and difficult to clear completely. Some secretions may drain backward into the throat, causing throat irritation, coughing, and phlegm production.
3. Facial pain or tenderness: Pain is usually localized to the cheek area where the maxillary sinuses are located. Pressing on the cheek may elicit obvious tenderness. The intensity of pain varies with disease progression and may worsen when changing head position, such as bending forward or lowering the head.
4. Reduced sense of smell: Due to nasal obstruction or inflammatory irritation of the olfactory mucosa, patients may experience decreased olfactory sensitivity, resulting in a duller perception of odors. In severe cases, temporary loss of smell may occur, though it typically improves gradually once the inflammation subsides.
5. Headache: Some patients may experience headaches characterized by dull or pressure-like pain, commonly related to the location of the maxillary sinuses. These headaches often occur in the morning or afternoon and may temporarily improve with rest or pain-relieving medications.
If the above symptoms persist for an extended period, timely consultation with an otolaryngologist (ear, nose, and throat specialist) is recommended for accurate diagnosis and proper treatment. Additionally, maintaining nasal hygiene and avoiding forceful nose-blowing can help prevent worsening or recurrence of the condition.
