Changing of the orbital volume after endoscopic transethmoid medial wall decompression combined with the endoscopic transethmoid intraconal fat-removal orbital decompression in thyroid associated ophthalmopathy / 中国内镜杂志

Objective To present the changing of the parameters of orbital volume after endoscopic transethmoid medial orbital wall decompression combined with the endoscopic transethmoid intraconal fat-removal orbital decompression in thyroid associated ophthalmopathy (TAO).Methods A retrospective chart was reviewed in 11 patients (20 eyes) receiving orbital decompression for the treatment of exophthalmos secondary to TAO from September 2014 to August 2015. All patients diagnosed TAO were in stable and inactive phase at least for 6 months. High-resolution computed tomography (HRCT) scan were performed in all patients before and 3-month after surgery. CT scan of orbit and computer-aided measurement software were used to measure the exophthalmos. Changing of the parameters of orbital volume were recorded for analysis its relationship with the amount of proptosis reduction.Results The exophthalmos was signiifcantly decreased after surgery. Medial rectus volume, fat volume and orbital volume were larger postoperatively. The changing of rectus volume and fat volume both had negative correlationship with the amount of proptosis.Conclusions The thickening of medial rectus 3-month postoperative may due to the removing of medial wall of orbit during the surgery. The stimulation of the surgery may be another reason. The changing of rectus volume and fat volume both had negative correlationship with the amount of proptosis.

Surgical treatment modalities of thyroid ophthalmopathy

This report presents the use of various surgical treatment modalities in patients who were diagnosed as having thyroid ophthalmopathy. The records of 53 patients who received surgery because of thyroid ophthalmopathy at the Department of Ophthalmology, Yonsei University College of Medicine between Sept. 1996 and Jan. 2000 were retrospectively evaluated. Among the 53 patients, there were 30 females and 23 males. The mean ages of the patients were 40.8 +/- 17.1 years. Orbital wall decompression (52.8%) was the most frequently performed surgery followed by lid surgery (49.1%) and strabismus surgery (26.4%). Only one type of surgery was performed on 86.8% of the patients while 13.2% received more than one type of surgery. Among the many different types of surgeries possible in patients that have thyroid ophthalmopathy, orbital wall decompression, lid surgery, and strabismus surgery are the most commonly used surgical methods for treatment.
