Introduction
In general, left maxillary sinus cysts may be caused by trauma, allergic reactions, sinusitis, periodontitis, anatomical abnormalities, or other factors, and require management based on individual circumstances. Patients with left maxillary sinus cysts should maintain nasal hygiene in daily life, avoid forceful nose-blowing to prevent cyst rupture or worsening of infection. Regular follow-up examinations are necessary to monitor changes in the cyst and adjust the treatment plan promptly as needed.
Generally, left maxillary sinus cysts may be caused by trauma, allergic reactions, sinusitis, periodontitis, anatomical abnormalities, and other factors. Treatment should be tailored according to the specific condition.
1. Trauma: Injury to the head or face may cause internal sinus bleeding and tissue damage, thereby affecting the normal drainage of mucus. When mucus accumulates in the sinus cavity, a cyst may develop.
2. Allergic reactions: When allergic rhinitis or other systemic allergic reactions affect the left maxillary sinus, inflammatory mediators can cause congestion and edema of the maxillary sinus mucosa, increased mucus secretion, and impaired drainage, leading to gradual formation of a cyst. It is recommended to take medications such as loratadine tablets or cetirizine hydrochloride tablets under medical guidance.
3. Sinusitis: Sinusitis can cause obstruction of the sinus openings, preventing normal drainage of secretions and resulting in mucus accumulation within the sinus cavity and the formation of a cyst. It is recommended to use medications such as ephedrine hydrochloride nasal drops or amoxicillin-potassium clavulanate tablets under medical supervision.
4. Periodontitis: Periodontitis may spread upward through the apical foramen or the intertrabecular spaces of the alveolar bone, involving the maxillary sinus and causing maxillary sinusitis, which gradually leads to mucus accumulation and cyst formation. It is recommended to perform dental cleaning and subgingival curettage under medical guidance to remove dental plaque and calculus around the teeth. For larger cysts, endoscopic sinus surgery may be considered under medical advice.
5. Anatomical abnormalities: Some individuals may have congenital abnormalities such as narrow maxillary sinus openings, abnormal sinus septa, or unfavorable sinus ostium positions, which may hinder the normal mucus drainage from the maxillary sinus, leading to gradual mucus accumulation and cyst formation. Usually, nasal endoscopic surgery is performed under medical guidance to correct the abnormal anatomy and remove the cyst, helping to restore normal drainage function of the maxillary sinus.
Patients with left maxillary sinus cysts should maintain nasal hygiene and avoid forceful nose-blowing to prevent cyst rupture or worsening infection. Regular follow-up visits are recommended to monitor cyst changes and adjust the treatment plan timely according to the individual condition.
