Surgical ciliated cysts, also known as implantation cysts or postoperative maxillary cysts, are uncommon cystic formations predominantly arising in the posterior maxillary region after radical maxillary sinus surgery. Herein, we present the case of a 28-year-old male patient who had previously undergone orthognathic surgery and later experienced a minor car accident without major consequences. Approximately four years after surgery, the patient sought dental care due to the presence of a painless swelling in the maxillary region. Upon intraoral examination, the swelling extended from the area around the right canine to the upper left molar, covered by red mucosa. Image studies revealed an extensive well-defined osteolytic lesion causing thinning, erosion, buccal cortical plate perforation, and root resorption. An incisional biopsy was performed, and microscopic examination revealed a cystic lesion lined by ciliated respiratory-type epithelium and capsule variably fibrotic with sparse chronic inflammation. The final diagnosis was surgical ciliated cysts. The treatment approach involved decompression followed by enucleation and curettage, with the addition of bone grafting and the application of Leukocyte-Platelet Rich Fibrin (L-PRF). The patient has been under clinical follow-up for approximately 17 months with no signs of recurrence. A careful morphological evaluation is essential to avoid misdiagnosis and ensure a satisfactory treatment approach. In conclusion, this case highlights the importance of accurate diagnosis and appropriate treatment approaches for surgical ciliated cysts to ensure favorable patient outcomes.
