BACKGROUND AND OBJECTIVES: Various surgical approaches have been employed for the complete resection of inverted papilloma (IP) of the nose and paranasal sinus. Sacrificing the inferior turbinate (IT) and nasolacrimal duct (NLD) is often unavoidable due to the anatomy of maxillary sinus. However, the prelacrimal recess approach (PLRA) provides a wider entrance to the maxillary sinus without the ablation of NLD and IT. We present seven cases of IP successfully treated by the PLRA. SUBJECTS AND METHOD: We collected data from seven different cases involving patients who underwent resection of IP by means of the PLRA from 2016 to 2017. If the lesion could not be removed first via middle meatal antrostomy (MMA), then PLRA was attempted. The surgical specimens were all confirmed to be IP. RESULTS: Preoperative imaging studies demonstrated that the lesions of IP were located mainly in the maxillary sinus. All of the seven patients had unilateral lesions and all tumors were completely resected via PLRA. The follow-up ranged from 3 to 24 months, during which no recurrence or complications were observed in any of the seven patients. CONCLUSION: PLRA provides an adequate operation field without unfavorable scars. It allows the preservation of sinus structure and function. PLRA is feasible and can be used for the diffuse maxillary sinus IP.

Hepatocellular carcinoma (HCC) is a common neoplasm, and its metastasis to the head and neck area is rare. We herein describe a unique case of HCC metastasis to the dorsal tongue. A 54-year-old male who was already diagnosed with HCC visited our hospital complaining of dysphagia and a progressively enlarging dorsal tongue mass. We operated to excise on the mass using CO₂ laser including mucosal margin and deep margin. The diagnosis of HCC metastasis was confirmed immunohistochemically. After 2 weeks of follow-up, the patient did not exhibit any evidence of complication and could eat orally without any problem. Further treatment to the other metastatic lesion was rejected, and the patient was followed up for more than six months. We introduce this first case of metastatic HCC in the dorsal tongue. With the extended life expectancy of HCC patients, the incidence of rare metastasis is expected to increase.

OBJECTIVE: Injuries of upper cervical spine are potentially fatal. Thus, appropriate diagnosis and treatment is essential. In our institute, preoperative computed tomography angiography (CTA) has been performed for evaluation of injuries of bony and vascular structure. The authors confirmed the engorged venous plexus within injured posterior neck muscle. We have this research to clarify the relationship between the engorged venous plexus and engorged vein. METHODS: A retrospective review identified 23 adult patients who underwent 23 posterior cervical spine surgeries for treatment of upper cervical injury between 2013 and 2015. Preoperative CTA was used to identify of venous engorgement within posterior neck muscle. The male to female ratio was 18:5 and the mean age was 53.5 years (range, 25-78 years). Presence of venous engorgement and estimated blood loss (EBL) were analyzed retrospectively. RESULTS: The EBL of group with venous engorgement was 454.55 mL. The EBL of group without venous engorgement was 291.67 mL. The EBL of group with venous engorgement was larger than control group in significant. CONCLUSION: The presence of engorged venous plexus is important factor of intraoperative bleeding. Preoperative CTA for identifying of presence of engorged venous plexus and fine operative techniques is important to decrease of blood loss during posterior cervical spine surgery.

Sialolithiasis is the most common disorder associatd with major salivary glands. It may form in any salivary glands or ducts, but is reported to occur more often in the submandibular gland than in the parotid or sublingual gland. Although the pathogenesis is not perfectly revealed, there appear to be several factors that predispose the submandibular gland duct to be a common site of sialolithiasis. Sialolithiasis occurs as a consequence of the precipitation of calcium salts around a central nidus of desquamated epithelial cells, inflammatory cells, mucoid gels or foreign body. However, it is not a common thing that foreign body entered into the salivary duct through duct orifice may act as the initiating factor. We have recently experienced a case in a 52-year-old female, in which sialolithiasis seems to have formed due to a a foreign body, a fish bone, in the right submandibular gland duct.

BACKGROUND: This study was to investigate the feasibility of real-time 3-dimensional echocardiography (RT3DE) for the analysis of biventricular ejection fractions and volume measurements in patients with cor pulmonale and the correlations of RT3DE results with 64-slice multi-detector cardiac computed tomography (64-MDCT) results. METHODS: This study included a total of 22 patients (59.3 +/- 16.6 years of age; 10 males and 12 females) who showed flattening or reverse curvature of the interventricular septum and severe pulmonary hypertension [mean right ventricular (RV) systolic pressure = 66.8 +/- 19.7 mmHg] on 2-dimensional transthoracic echocardiography due to cor pulmonale. Biventricular end-diastolic and end-systolic volumes were measured by RT3DE and 64-MDCT. The severity of D-shaped deformation was evaluated by using left ventricular (LV) eccentricity index (ratio of diameters parallel/perpendicular to the interventricular septum on parasternal short axis images of the papillary muscle level). RESULTS: There were moderate correlations between biventricular volumes measured by RT3DE and 64-MDCT except for LV end-systolic volume (59.8 +/- 17.1 vs. 73.2 +/- 20.2 mL, r = 0.652, p = 0.001 for LV end-diastolic volume; 30.6 +/- 9.1 vs. 30.8 +/- 12.5 mL, r = 0.361, p = 0.099 for LV end-systolic volume; 110.1 +/- 42.9 vs. 171.1 +/- 55.3 mL, r = 0.545, p = 0.009 for RV end-diastolic volume; and 80.9 +/- 35.0 vs. 128.7 +/- 45.1 mL, r = 0.549, p = 0.005 for RV end-systolic volume respectively). CONCLUSION: This study suggests that RT3DE may be a modest method for measuring distorted biventricular end-systolic and end-diastolic volumes in patients with cor pulmonale.

Achondroplasia is the most common non-lethal skeletal dysplasia. Underdevelopment and premature ossification of bones result in characteristic craniofacial and spinal abnormalities. Achondroplastic dwarfs have low fertility rates and require delivery by cesarean section due to their cephalo-pelvic disproportion. Controversy exists regarding the ideal anesthesia for an achondroplastic parturient dwarf for urgent cesarean section. Anesthesia, whether general or regional, presents many potential problems during cesarean section. We report the experience of the epidural anesthesia in an achondroplastic dwarf undergoing elective cesarean section.

We described here a patient who presented with symptoms of heart failure who was found to have severe bilateral impairment of atrioventricular inflow. Primary cardiac lymphoma (PCL) with extensive involvement of the two atria, pericardium and myocardium is an extremely rare tumor in immunocompetent patients. We report here a case of PCL in an immunocompetent patient with involvement of both atria and the atrial septum. The tumor had a butterfly shape. We could not do surgical excision because of the massive pericardiac invasion. The diagnosis was B-cell lymphoma and this was confirmed by the pericardiac biopsy.

Intraoperative formation and management of a thrombus in right atrium has been reported occasionally. Nevertheless, it is rare that a right atrial thrombus with unstable hemodynamic changes detected by transesophageal echocardiography is resolved spontaneously. We report upon the 44-year-old woman, who had a right atrial thrombus detected by transesophageal echocardiography during laparoscopic assisted vaginal hysterectomy and resolved during thromboembolectomy.

BACKGROUND: This study was designed to compare the effect of dexmedetomidine and remifentanil used in anesthetic induction on hemodynamic change after direct laryngoscopy and tracheal intubation. METHODS: A total of 90 ASA class 1 or 2 patients were randomly assigned to one of 3 groups to receive one of the following treatments in a double-blind manner: normal saline (Group C, n = 30), dexmedetomidine 1 microg/kg (Group D, n = 30), remifentanil 1 microg/kg (Group R, n= 30). Anesthesia was induced with propofol 2 mg/kg and rocuronium 0.6 mg/kg and maintained with 2 vol% sevoflurane and 50% nitrous oxide in oxygen. In group D, dexmedetomidine 1 microg/kg was infused for 10 min before tracheal intubation. Patients in group R was received 1 microg/kg of remifentanil 1 minute before tracheal intubation. The systolic blood pressure, diastolic blood pressure and heart rate were recorded from entrance to operation room to 5 min after tracheal intubation. RESULTS: The percent increase in systolic and diastolic blood pressure due to tracheal intubation in group D and R were significantly lower than that of group C (P < 0.05). The heart rate 1 min after tracheal intubation was lower in groups R and D than in the group C (P < 0.05). CONCLUSIONS: In healthy normotensive patients, the use of dexmedetomidine during anesthetic induction suppressed a decrease in blood pressure due to anesthetic induction and blunted the hemodynamic responses to endotracheal intubation.
