Mucosal cyst aspiration in conjunction with maxillary sinus elevation: A clinical cohort study

Area of Science:

• Oral and Maxillofacial Surgery
• Dental Implantology
• Cystic Lesion Management

Background:

• Maxillary sinus mucosal cysts pose challenges for dental implant placement.
• Existing treatment strategies for these cysts during sinus augmentation are debated.
• A need exists for effective and safe therapeutic approaches.

Purpose of the Study:

• To evaluate a combined technique of needle aspiration and maxillary sinus augmentation (MSA) for treating maxillary sinus cysts.
• To assess the safety and efficacy of this combined approach for dental implant restoration.
• To report long-term outcomes, including implant survival and bone stability.

Main Methods:

• A cohort study involving 15 patients (18 sinuses) undergoing simultaneous cyst aspiration and MSA.
• Dental implants were placed in the augmented sinuses.
• Follow-up included clinical evaluation, quality of life assessment, and CBCT imaging.

Main Results:

• 100% implant success and 97.8% survival rates at 1 and 5 years post-loading.
• Average crestal bone resorption of 0.3 mm at 5 years, indicating bone stability.
• 81% of sinuses showed no cyst reformation at 5-year follow-up; remaining cases had smaller, asymptomatic cysts.

Conclusions:

• Maxillary sinus mucosal cyst aspiration combined with MSA is a viable and effective treatment option.
• This technique offers predictable outcomes for dental implant success in patients with maxillary sinus cysts.
• The procedure ensures bone stability and patient quality of life.
