Problems Relating to Postoperative Maxillary Cyst

“…According to the mechanism of POMC generation, cysts are formed once in the maxillary sinus osteoclasts, producing many osseous overhangs around the cyst. Therefore, it is essential to release the bone in order to firmly release the cyst [7]. Previous reports have described the effective use of pedunculated mucoperiosteal flaps to prevent recurrence [3,4,5].…”

Although the number of postoperative maxillary cyst (POMC) cases has declined recently, a few reports of refractory cases have also been reported. The indications for endoscopic sinus surgery (ESS) for POMC removal are broadening and attempts to prevent postoperative recurrence at the cyst opening site have been widely investigated. Here, we have advocated our original pedunculated mucoperiosteal flap (CLAP flap; covered lateral and posterior wall flap of the maxillary sinus), where the bony area exposed intraoperatively is covered, to prevent postoperative recurrence. We have also presented the method for creating the CLAP flap. We classified the POMC as being medial, lateral, or anterior superior type and performed ESS. We introduced the CLAP flap after 2015 for the lateral type and some of the medial types of POMCs. We examined the cyst opening rate using computed tomography, age, sex, cyst position, and a follow-up period in four patients (five sides) who did not undergo flap surgery, but who were managed in our hospital in 2015, and in eight patients (nine sides) who underwent the CLAP flap technique in our hospital. In the group with the CLAP flap, the cyst opening rate was significantly higher (P \ 0.05). The CLAP flap was effective for preventing postoperative bony regrowth. It may be one of the options for covering the exposed bone surface as widely as possible.

“…[7] Further, Mohri et al (1977) attributed the origin of the lesions to the closure of both the natural ostium and the intranasal opening following a surgical procedure. [8] The conventionally termed "surgical ciliated cyst" is commonly encountered among the Japanese population but appears to be a rare entity in the most other parts of the world. [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.…”

Surgical ciliated cysts or post-operative maxillary cysts are benign cystic lesions usually induced after a surgical procedure in the maxillofacial area. It is a cystic lesion that develops, following a radical sinus surgery to treat maxillary sinusitis. The cyst progressively enlarges due to the osmotic diff erence causing destruction of the adjacent bone and structures. The clinical scenario may be identical to a radicular cyst if a nonvital tooth is involved. This is a case report of a healthy 17-year-old adolescent with the complaint of swelling in the right side of the face for the past 2 years.
