Prevalence of Postoperative Maxillary Cyst Significantly Higher in Japan

Transnasal endoscopic surgery of post-operative maxillary cysts

“…7 In Japan, post-operative maxillary cyst is the most common cause of sinus mucocele. 5,9 Computed tomography examination and magnetic resonance imaging are also useful for the diagnosis of post-operative maxillary cyst. 8 Post-operative maxillary cyst is diagnosed based on clinical symptoms, previous maxillary surgery, radiography and histology.…”

“…4 Although relatively common in Japan, post-operative maxillary cyst is rare in Europe and the USA. 5 Consequently, fewer studies have investigated post-operative maxillary cyst treatment using endonasal functional endoscopic sinus surgery (FESS). Conventional post-operative maxillary cyst treatment is comprised of complete excision of the mucocele lining using the canine fossa approach; FESS has become the preferred post-operative maxillary cyst treatment in Japan in recent years.…”

Surgical ciliated cyst of the maxilla following maxillary osteotomy: a case report

“…Surgical ciliated cysts (also known as post‐operative maxillary cyst, post‐operative paranasal cyst or mucocele, respiratory implantation cyst and surgical implantation cyst), first described by Kubo in 1927, are reportedly more common in the Japanese population compared with other populations. They occur in up to 20% of Japanese patients following radical maxillary sinus surgery.…”

“…The surgical ciliated cyst has a slight male predilection. There is a wide presenting age range from 21 to 80 years, and it is reported to occur 3–61 years following maxillary sinus surgery.…”

Ciliated cyst of the maxilla following trauma: An unusual case report

“…[9] It has a slight male predilection with a wide presenting age range from 21 to 80 years, and it is thought to occur 3-61 years following a maxillary surgical procedure. [10] Radiographs reveal well-defi ned radiolucent areas in close relation to the maxillary sinus. In a series of cases reported by Yamamoto, Takagi most of the cases were unilocular with very few showing a multilocular presentation.…”
