Abstract

Retention cyst of the maxillary sinus is a benign lesion produced from obstruction of a seromucous gland or duct. It is mostly asymptomatic but sometimes is accompanied by facial pain, headache, nasal obstruction, and other symptoms. However, there are some debates on whether the symptoms are directly related with retention cyst. These cysts typically do not require treatment. However, when accompanied by symptoms, treatment can be administered for diagnostic and therapeutic purposes. We report a case in which facial pain is caused by a maxillary retention cyst suspended from an infraorbital nerve.

Figure

• 

  Fig. 1 A: Preoperative endoscopic findings of nasal cavity. the patient got endoscopic sinus surgery about 5 years ago. There was no sign of mucosal swelling, purulent discharge. B: There was cystic lesion originating from superolateral wall of maxillary sinus. The cyst was filled with amber-colored fluid. C: Intraoperative endoscopic findings of the patient, there is pedunculated cystic lesion, originating from lateral wall of maxillary sinus. D: Postoperative findings of the patients, there was no sign of cyst recurrence. MT: middle turbinate, Asterisk: Cyst.

  Fig. 2 A: Radiographic findings of paranasal sinus series. there is round-shaped, radiopaque lesion in maxillary sinus. B and C: The patient's axial & coronal view of paranasal sinus computed tomography, there is round-shpaed, soft tissue density attached at infraorbital wall, near infraorbital nerve of maxillary sinus. Arrow: infraorbital nerve.

  Fig. 3 Pathologic findings of the cyst. The epithelium of the cyst consists of pseudostratified ciliated respiratory epithelium. And there are findings of chronic inflammation with a few eosinophil.
