Transnasal endoscopic surgery of post-operative maxillary cysts

Area of Science:

• Otolaryngology
• Endoscopic Sinus Surgery

Background:

• Post-operative maxillary cysts can cause significant patient discomfort and complications.
• Accurate diagnosis and appropriate surgical intervention are crucial for effective management.

Purpose of the Study:

• To investigate the indications and efficacy of transnasal endoscopic surgery for treating post-operative maxillary cysts.
• To evaluate the outcomes of different surgical approaches in managing these cysts.

Main Methods:

• A retrospective review of 118 patients (148 procedures) with post-operative maxillary cysts.
• Analysis of surgical techniques, including transnasal endoscopic approach and combined approaches.

Main Results:

• Transnasal endoscopic surgery was performed in 97.3% of cases.
• A combined approach was used for cysts distant from the nasal cavity with thick bony walls.
• Recurrence occurred in 4.2% of patients, successfully managed with revision surgery.

Conclusions:

• Transnasal endoscopic surgery is a highly effective treatment for post-operative maxillary cysts.
• This approach is particularly suitable for cysts accessible via the nasal cavity.
• Cysts located distant from the nasal cavity may require alternative surgical strategies.
