The incidence of hyperpneumatization of the maxillary sinus is approximately 8% as reported in the most recent and relevant study 1. This condition refers to an abnormal enlargement of the maxillary sinus beyond its normal anatomical boundaries. The maxillary sinus may extend into adjacent structures such as the zygomatic process, alveolar process, or hard palate. This anatomical variation becomes clinically significant during dental procedures, particularly implant placement in the posterior maxilla, where reduced bone height due to hyperpneumatization may necessitate sinus lift procedures. Some of the key factors that influence maxillary sinus pneumatization include tooth loss, age-related changes, and extraction of maxillary posterior teeth, as the absence of functional forces from teeth allows for progressive expansion of the sinus cavity into the alveolar process 2. It is essential to consider these factors when evaluating and treating patients with hyperpneumatization of the maxillary sinus to minimize potential complications and ensure optimal outcomes. The etiology of hyperpneumatization is multifactorial, potentially involving genetic factors, hormonal influences, and adaptive responses to tooth loss 3. In clinical practice, it is crucial to assess the extent of sinus pneumatization and its potential impact on dental procedures, such as implant placement, to provide personalized treatment plans and minimize the risk of complications. Overall, the incidence of hyperpneumatization of the maxillary sinus is a critical consideration in dental and maxillofacial surgery, and its evaluation and management require a comprehensive understanding of the underlying factors and potential consequences.
