Involutional lower eyelid entropion: causative factors and therapeutic management.

Purpose: To summarize proposed causative factors and the outcomes of surgical practices for involutional lower eyelid entropion.

Methods: We reviewed the literature on proposed causative factors and the outcomes of surgical practices for involutional lower eyelid entropion, searched on PubMed.

Results: Vertical and horizontal laxities of the lower eyelid, and overriding of the preseptal orbicularis oculi muscle onto the pretarsal orbicularis oculi muscle have been proposed as the major causes of involutional lower eyelid entropion.

Rescue technique for complete removal of an accidentally ruptured orbital dumbbell deep dermoid cyst: A case report.

Purpose: To report a rescue technique for complete removal of an accidentally ruptured orbital dumbbell deep dermoid cyst.

Observations: A 33-year-old female presented with left proptosis with retrobulbar discomfort for 3 months. Computed tomography images showed an orbital dumbbell deep dermoid cyst.

Lagophthalmos caused by cicatricial adhesion of orbital adipose tissue to orbital roof: A case report.

Purpose: To report a case of lagophthalmos caused by cicatricial adhesion of orbital adipose tissue to the orbital roof.

Observations: A 23-year-old female was presented with right lagophthalmos. Five months prior to consult at our clinic, she suffered from a penetrating trauma to the frontal lobe of the brain through the right orbital roof with cerebrospinal fluid leakage.

Bilateral orbital marginal zone B-cell lymphoma of the mucosa-associated lymphoid tissue in a patient with hepatitis B virus infection.

Purpose: To report a case of marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) in the bilateral orbit with chronic hepatitis B virus (HBV) infection.

Observations: A 72-year-old man with chronic HBV infection presented with a bilateral proptosis with slight restriction of ocular motility for 9 months. Computed tomographic images showed well-defined, isodense masses in the bilateral superolateral orbit.

Interlower and postlower eyelid retractor fat pads: a cadaveric microscopic study.

Background: To report the histological microscopic anatomy of the interlower and postlower eyelid retractor (LER) fat pads.

Methods: In this experimental microscopic study, 31 exenterated orbits from 31 Japanese cadavers (19 right and 12 left; 15 male and 16 female; mean age of death, 81.0±8.

Orbital myxoma comorbid with acute myelomonocytic leukemia.

We report the first case of orbital myxoma in a 10-year-old girl with a history of acute myelomonocytic leukemia diagnosed at the age of 10 months. She presented with a mass in the right orbit, which was excised completely. There was no recurrence during the 6 months of follow-up.

Accidental Ingestion of Nasal Packing Gauze during Endonasal Endoscopic Dacryocystorhinostomy under Local Anesthesia: A Case Report.

Purpose: To report a case of accidental ingestion of a nasal packing gauze during endonasal endoscopic dacryocystorhinostomy (en-DCR) under local anesthesia.

Case Report: A 66-year-old female patient underwent an en-DCR for a right acquired nasolacrimal duct obstruction. The surgery was performed in a supine position under local anesthesia.

Cystic mucosa-associated lymphoid tissue lymphoma of lacrimal gland associated with vision loss: A case report.

Purpose: To report an atypical case of cystic extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) of lacrimal gland associated with vision loss.

Observations: An 89-year-old woman was presented with a rapidly progressing proptosis, lagophthalmos, and vision loss. Endophthalmitis was also present.

Primary Marginal Zone B-Cell Lymphoma of the Mucosa-Associated Lymphoid Tissue of the Lacrimal Sac Found with Epiphora: A Case Report.

We report a case of a primary marginal zone B-cell lymphoma of the mucosa-associated lymphoid tissue of the lacrimal sac, which was found in a patient with epiphora without palpable mass. Magnetic resonance imaging demonstrated mucosal thickening of the lacrimal sac with a patent lumen, consistent with the intraoperative finding. Epiphora resolved, which was confirmed by smooth syringing, 1 month after starting the immunotherapy.

Solitary Fibrous Tumor in the Lacrimal Gland Fossa: A Case Report.

Solitary fibrous tumors (SFTs) are benign, spindle-cell tumors of mesenchymal origin that are usually seen in the superior orbital area in adults. We report a rare case of SFT in the lacrimal gland fossa that developed in a young female. A 25-year-old woman had a 6-month history of a progressive painless mass in the left upper eyelid accompanied by proptosis.

Risk Factors for Local Recurrence or Metastasis of Eyelid Sebaceous Gland Carcinoma After Wide Excision With Paraffin Section Control.

Purpose: To identify risk factors for local recurrence and metastasis of sebaceous gland carcinoma (SGC) after wide excision with paraffin section control.

Design: Retrospective, observational case-control study.

Methods: Setting: Single institution.

Prevention of re-obstruction in watery eye treatment: three-flap technique in external dacryocystorhinostomy.

Purpose: To examine the surgical outcome of three-flap external dacryocystorhinostomy (3-flap ex-DCR) based on the most common site of granulation occurrence in no-flap endonasal DCR (no-flap en-DCR).

Methods: This was a retrospective observational study. We first examined the location of granulation occurrence in the osteotomy site using nasal endoscopy after no-flap en-DCR on 53 sides of 37 patients (5 male, 32 female) with nasolacrimal duct obstruction.

Characteristics of Dehiscence of Lamina Papyracea Found on Computed Tomography Before Orbital and Endoscopic Endonasal Surgeries.

The aim of this study was to identify characteristics of dehiscence of the lamina papyracea found on computed tomography (CT) before orbital and endonasal endoscopic surgeries.The authors retrospectively reviewed the medical records of all patients who underwent orbital tumor removal, orbital decompression, and dacryocystorhinostomy from January 2012 to December 2015. The diagnosis of dehiscence of the lamina papyracea was made based on a bone defect with protrusion of orbital fat into the ethmoid sinus on CT, with no history of orbital trauma and/or eye movement disturbance on the same side.
