Evaluation of maxillary sinus pneumatization amongst different age groups and genders: A CBCT based study

Area of Science:

• Dentistry
• Anatomy
• Radiology

Background:

• Maxillary sinus pneumatization (MSP) is a common anatomical variation.
• Excessive MSP can compromise alveolar bone height, increasing surgical risks and limiting prosthetic options.

Purpose of the Study:

• To evaluate maxillary sinus pneumatization in 200 adults across three age groups.
• To assess the relationship between MSP, age, gender, and posterior tooth sites.

Main Methods:

• Measurements of the distance between the maxillary sinus floor and nasal cavity floor were taken at posterior tooth sites.
• Participants were categorized into three age groups.

Main Results:

• Type I pneumatization was predominant across all groups, decreasing from the youngest to the oldest group.
• Men exhibited significantly greater MSP than women in the two younger age groups (p=0.004 and p=0.001).

Conclusions:

• Maxillary sinus pneumatization varies significantly by age and gender.
• Findings highlight the importance of considering MSP variations for dental implant treatment planning to mitigate surgical complications and optimize prosthetic outcomes.
