Delayed Ocular Motility Restriction After Endoscopic Sinus Surgery in a Patient With Chronic Rhinosinusitis and an Old Medial Orbital Wall Fracture.

The orbital complications of endoscopic sinus surgery, including diplopia and ocular motility restriction, are mainly caused by direct injury to the orbital structures. These complications are rare, but can have catastrophic consequences. Symptoms occur immediately after surgery in most cases.

Intraoperative Real-Time Localization of Normal Parathyroid Glands With Autofluorescence Imaging.

Context: This biomedical investigation is valuable for identification and localization of parathyroid glands during thyroidectomy, which can provide an intraoperative real-time visual guidance.

Objective: The objective of the study was to investigate the feasibility of real-time autofluorescence imaging of the parathyroid glands without exogenous contrast dye for their localization and demonstration of relation to the background tissues.

Setting: This research was undertaken at Kosin University Gospel Hospital.

Voice outcome according to surgical extent of transoral laser microsurgery for T1 glottic carcinoma.

Objectives/hypothesis: To evaluate the outcomes of transoral laser microsurgery (TLM) for T1 glottic carcinoma using longitudinal voice analysis.

Study Design: Retrospective analysis of medical records.

Methods: We conducted a retrospective review of 57 patients (50 T1a, seven T1b) who underwent TLM for T1 glottic carcinoma, and longitudinal voice analysis was performed before surgery, during the early postoperative period (within 3 months), and during the late postoperative period (more than 6 months).

Pathologic features of metastatic lymph nodes identified from prophylactic central neck dissection in patients with papillary thyroid carcinoma.

The importance of pathologic features of metastatic lymph nodes (LNs), such as size, number, and extranodal extension, has been recently emphasized in patients with papillary thyroid carcinoma (PTC). We evaluated the characteristics of metastatic LNs identified after prophylactic central neck dissection (CND) in patients with PTC. We performed a retrospective review of 1,046 patients who underwent unilateral or bilateral thyroidectomy with ipsilateral prophylactic CND.

Isolated trapdoor-type medial blowout fracture in an adult presenting horizontal diplopia treated by endoscopic endonasal approach.

Orbital blowout fracture frequently occurs along the floor or medial aspect of the orbital wall, which are the two thinnest areas of the bony orbit. True trapdoor injury of the orbit is less common and is rare as an isolated medial wall injury, because the medial orbital wall has several bony septa within the ethmoid sinus that provide support and decrease the risk of a trapdoor fracture. Additionally, the incidence of trapdoor-type blowout fracture in adults is lower than in children.
