Maxillary sinus floor augmentation is considered to play a critical role in dental implant treatment. Although many complications, such as maxillary sinusitis and infection, are well known, few reports are available on the risk of surgical ciliated cyst following the procedure. Here, we report a case of surgical ciliated cyst following maxillary sinus floor augmentation. A 55-year-old Japanese woman was referred to our hospital because of alveolar bone atrophy in the bilateral maxilla. We performed bilateral maxillary sinus floor augmentation by the lateral window technique without covering the window. The Schneiderian membrane did not perforate during the operation. She returned to our hospital after 9 years due to swelling of the left buccal region. Computerized tomography revealed a well-defined radiolucent area with radiodense border intraosseously localized in the left maxilla. We performed enucleation of the cyst with the patient under general anesthesia. Histological examination of the specimen showed a surgical ciliated cyst. In conclusion, the course of this patient has 2 important implications. First, the sinus membrane entrapped in the grafted bone without visible perforation and or tearing can develop into a surgical ciliated cyst. Second, there is a possibility that covering the lateral window tightly might prevent the development of a surgical ciliated cyst.

Neurenteric cysts, rare benign tumors, are most often found in the cervical or thoracic spinal cord, with intracranial occurrences being extremely uncommon. This case report describes a 52-year-old female with a neurenteric cyst in the cerebellopontine angle, presenting with headaches and balance disturbances. Magnetic resonance imaging (MRI) revealed a cystic lesion causing hydrocephalus, and surgical removal was performed using a retrosigmoid approach.

Median mandibular cyst is defined as an odontogenic cyst in a rare midline location. In spite of this definition, there have been two reports of a peculiar lesion, so-called "ciliated" median mandibular cyst associated with vital teeth, the origin of which cannot be explained in terms of odontogenic epithelium multipotentiality. We describe a thorough profile of an additional example.

A desmoplastic small round cell tumor (DSRCT) presented in a 13-year-old female with an acute abdomen due to torsion of a fallopian tube cyst. She was found to have an incidental 2 cm pedunculated, solid, and multicystic mass attached to the pelvic floor on laparoscopy. The neoplasm had a variably myxoid and spindle cell pattern with nests and cords of small cells, forming pseudocysts, and true cysts lined by ciliated epithelium which were PAX-8+ and ER+/PR+.

Intradural extramedullary bronchogenic cysts (IEBCs) are exceedingly rare congenital entities, composed of respiratory epithelial cells derived from the anomalous development of the embryonic foregut. Due to their exceptionally low morbidity, only limited cases are available. Consequently, the clinical features and optimal therapeutic approach remain poorly understood.

This reported case represents the first well-documented mandibular surgical ciliated cyst, following orthognathic surgery consisting of a combination of Le Fort I bimaxillary and sagittal osteotomy concomitantly with genioplasty, reported in a Brazilian patient. A case of 43-year-old female presenting a mandibular surgical ciliated cyst after 16 years of an orthognathic surgery, consisting of a combination of Le Fort I osteotomy and genioplasty, is reported. The cystic lesion was enucleated, and the histopathological analysis showed a cystic cavity lined by pseudostratified columnar respiratory-type epithelium presenting ciliated and mucous cells supported by fibrous connective tissue without inflammation.
