Oroantral communication as an osteotome sinus elevation complication.

Area of Science:

• Oral and Maxillofacial Surgery
• Dental Implantology
• Surgical Complications

Background:

• Sinus elevation is a common procedure to increase bone height in the posterior maxilla for dental implants.
• The crestal approach utilizes osteotomes to elevate the sinus membrane and place bone graft.
• This technique is generally predictable with few reported complications.

Observation:

• A case report details a 54-year-old female patient who developed an oroantral communication six days after a crestal sinus elevation surgery.
• The patient had a history of sleep apnea, for which she used a positive-pressure breathing mask nightly, and was also a smoker.
• The complication presented as a communication between the oral cavity and the maxillary sinus.

Findings:

• The oroantral communication was successfully closed with a rotated palatal flap.
• The patient discontinued the use of her positive-pressure breathing mask.
• Smoking and delayed healing were considered potential contributing factors to the complication.

Implications:

• Positive-pressure ventilation, such as CPAP for sleep apnea, may increase the risk of oroantral communication after sinus elevation surgery.
• Careful patient selection and management of risk factors like smoking are crucial for successful sinus elevation outcomes.
• This case highlights the importance of considering patient-specific factors and potential iatrogenic risks in sinus augmentation procedures.
