A Immediate Orbital Floor Reconstruction after Suprastructure Maxillectomy

Orbital wall Reconstruction After Maxillectomy For Maxillary Malignancies Is Very Challenging For Surgeons. Preservation Of The Orbit Is A Current Trend In This Procedure In Order To Increase The Quality Of Life Of Patients. If The Patients Have Not Achieved A Proper And Adequate Rigid Frame Of The Orbital Floor After Maxillectomy, They Can Suffer From Enophthalmos, Diplopia, And/Or Decreased Vision. The Authors Report One Case Of Immediate Orbital Floor Reconstruction Using A Bioreabsorbable Panel And Titanium Mesh After Successful Suprastructure Maxillectomy. The Functional And Plastic Outcomes Of The Orbit Were Excellent 4 Years After Surgery, Without Complications or recurrence.

A Case of Intraoral Drainage of Iatrogenic Parotid Sialocele after Sialendoscopy / 대한이비인후과학회지

A variety of treatment methods have been proposed for parotid sialocele. These include multiple aspirations and compression dressings, reconstruction of the duct, creation of a controlled internal fistula, superficial or total parotidectomy, radiation therapy and ductal ligation, etc. Most of these procedures are invasive with variables and often with poor success rates. This paper presents an unusual incidence of iatrogenic parotid sialocele after sialendoscopy and its management by a relatively simple, safe and effective technique, which is constituted of draining saliva into the intraoral.

Factors Associated with Metastatic Lymph Node Ratio, Extranodal Extension in the Central Compartment Node-Positive Papillary Thyroid Carcinoma / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Lymph node (LN) metastasis occurs in 30-80% of patients presenting for initial treatment of papillary thyroid carcinoma (PTC). The presence of LN metastasis is an independent risk factor for recurrence, which can add significant treatment morbidity. The LN ratio (LNR) and extranodal extension (ENE) have been shown to be important prognostic factors in PTC. The purpose of this study was to assess the characteristic features of LNR and ENE. SUBJECTS AND METHOD: We undertook a retrospective study of 411 patients treated between January, 2011 and December, 2013 for central compartment node-positive PTC by thyroidectomy and central compartment neck dissection (CCND) at our institution. We compared various clinicopathologic parameters such as age, gender, tumor size, multifocality, bilaterality, local invasion, extrathyroidal extension and aggressive variants between LNR and ENE. RESULTS: The significant associated factors for high LNR (defined as higher than 0.5) in multivariate analysis were gender (p=0.001, odds ratio=2.285) and multifocality (p=0.027, odds ratio=2.092). On the other hand, the significant associated factors for ENE in multivariate analysis were primary tumor size (p=0.023, odds ratio=1.965) and local invasion (p=0.043, odds ratio=1.870). CONCLUSION: Being male, multifocality, large primary tumor size (defined as larger than 1 cm) and local invasion were revealed as associated factors for LNR and ENE. Therefore, elective CCND should be considered for patients with PTC, for whom a thorough investigation of associative factors should be made before surgery.

Application of Ultrasonic Bone Aspirator in Transnasal Endoscopic Dacryocystorhinostomy : A Case Report

Transnasal endoscopic dacryocystorhinostomy (eDCR) has been performed with relative ubiquity since the introduction of the rigid nasal endoscope, with multiple reports found in the literature. Multiple techniques have been used for lacrimal osteotomy, including standard rongeurs, laser, radiofrequency and microdrill. The ultrasonic bone aspirator (UBA) has been described for a variety of neurosurgical procedures and was initially studied in orbital and lacrimal surgery by Sivak-Callcott et al. We report a 74-year-old female patient who suffered from epiphora and pus-like discharge of the right eye. The bone of the lacrimal sac fossa was thinned and removed using an ultrasonic bone aspirator. The patient had a significant symptom improvement without any complications related to UBA use. We applied an ultrasonic bone aspirator for a patient with lacrimal duct stenosis and report a successful result.
