[Retrobulbar hematoma in endoscopic endonasal dacryocystorhinostomy].

Recently, an increase in the number of operations on the lacrimal ducts performed by otorhinolaryngologists has been noted throughout the world. During these operations, intra- and postoperative complications may develop, which require the intervention of an ophthalmologist. A rare complication of endoscopic dacryocystorhinostomy is the development of retrobulbar hemorrhage. This article presents a clinical case of the development of retrobulbar hemorrhage in endoscopic dacryocystorhinostomy. The patient with dacryocystitis underwent endoscopic dacryocystorhinostomy. Preoperative computed tomography revealed a lack of bone tissue in the lacrimal sac fossa. Severe bleeding was noted during the operation. Against the background of tamponade of the formed anastomosis, a growing exophthalmos, conjunctival chemosis, subconjunctival hemorrhage were noted. After removing the tampon, a positive trend was noted. Dexamethasone solution was intraoperatively intravenously administered, in the postoperative period - methylprednisolone solution. According to computed tomography data, exophthalmos persisted on the first day after the operation, hematoma was localized. Visual functions are unchanged. Six months after the operation, the patient had no complaints. According to the computed tomography data, a functioning dacryorhinostomy anastomosis was determined. Often, an interdisciplinary approach to such complications is required, since it can provide full orbital decompression, as well as adequate postoperative management of the patient, which contributes to the most complete ophthalmic rehabilitation. The interaction of otorhinolaryngologists and ophthalmologists in such cases is an indispensable condition for the safety of the operation.
