Aim of the study:

Identify variants of maxillary sinus pathologies, its clinical presentations, radiological findings and surgical managements.

Maxillary sinus diseases are common and numerous disorders that affect this anatomical area. As lesions are frequently allowed to grow to a significant size before becoming symptomatic, patients often present late, which can make management options more limited and difficult. Proper evaluation both clinically and with appropriate imaging allows accurate diagnosis, and lesions can often be successfully managed endoscopically

Inclusion Criteria:

• Only patients with isolated maxillary sinus lesions , with varying degrees of sinus opacity who were indicated for surgery.

Exclusion Criteria:

• Patients who had pan sinuses lesions or those with significant involvement of the other paranasal sinuses than maxillary sinus were excluded.

All patients with the isolated maxillary sinus lesions were subjected to

1. Detailed history, general clinical examination & ENT examination, routine investigations, diagnostic nasal endoscopy.
2. CT scan PNS
3. The surgical approaches and intraoperative findings were recorded either endoscopicallay or combined approach .
4. The pathological diagnoses were reviewed postoperatively.
