Nasolabial cyst is a rare, non-odontogenic cyst that occurs in the submucosa of the anterior nasal floor. Its most likely origin is known to be remnants of the nasolacrimal duct. The patient usually comes to the hospital for swelling or pain in the nasolabial area, and the diagnosis is made by combining clinical features, radiologic imaging, and histological test. The most commonly used treatment is surgical excision via sublabial approach. A 40-year-old male, who had undergone maxillary orthognathic surgery for malocclusion 11 years ago, visited our hospital for pain and swelling of the nasolabial folds that had persisted for a year. A large nasolabial cyst with a size of 4.8×3.3×3.1 cm was confirmed on paranasal sinus CT, and surgical excision was performed via sublabial approach. The pathologic finding was a cyst lining consisting of ciliated pseudostratified columnal epithelium and goblet cells, consistent with the characterization of a nasolabial cyst. No recurrence was observed during follow-up for 3 months.
Objectives: This study was performed to investigate the correlation between subjective residual dizziness and objective postural imbalance after successful canalith repositioning procedure (CRP) in benign paroxysmal positional vertigo (BPPV) by using questionnaires and modified Clinical Test of Sensory Integration and Balance (mCTSIB). Methods: A total of 31 patients with BPPV were included prospectively in the study. All included patients were successfully treated after initial CRP and their symptoms and nystagmus disappeared. Two weeks after CRP, all patients were asked to fill out the questionnaire including both Dizziness Handicap Inventory (DHI) and visual analog scale (VAS). We also conducted mCTSIB 2 weeks after CRP. We divided patients into two groups according to VAS: RD (residual dizziness) group, VAS>0; non-RD group, VAS=0. We compared age, number of CRP, rates associated with three semicircular canals, DHI score and mCTSIB results between two groups. In addition, we analyzed the correlation between DHI score and mCTSIB results. Results: There were no significant differences in age, number of CRP, and rates associated with three semicircular canals between the two groups. RD group showed significantly higher DHI score and abnormal mCTSIB results than the non-RD group (<i>p</i><0.05). DHI score and the number of abnormal mCTSIB showed a statistically significant correlation. Conclusions: We demonstrated the correlation between DHI score and mCTSIB after successful CRP for BPPV. It also represents that subjective residual dizziness is correlated with objective postural imbalance even after successful CRP. Therefore, mCTSIB would be a useful test to evaluate both residual dizziness and postural imbalance after CRP in BPPV.
Background and Objectives Vocal fold (VF) scar is known to be the most common cause of dysphonia after laryngeal microsurgery (LMS). Steroids reduce postoperative scar formation by inhibiting inflammation and collagen deposition. However, the clinical evidence of whether steroids are helpful in reducing VF scar formation after LMS is still lacking. The purpose of this study is to determine whether intralesional VF steroid injection after LMS helps to reduce postoperative scar formation and voice quality.Materials and Method This study was conducted on 80 patients who underwent LMS for VF polyp, Reinke’s edema, and leukoplakia. Among them, 40 patients who underwent VF steroid injection after LMS were set as the injection group, and patients who had similar sex, age, and lesion size and who underwent LMS alone were set as the control group. In each group, stroboscopy, multi-dimensional voice program, Aerophone II, and voice handicap index (VHI) were performed before and 1 month after surgery, and the results were statistically analyzed.Results There were no statistically significant differences in the distribution of sex, age, symptom duration, occupation and smoking status between each group. Both groups consisted of VF polyp (n=21), Reinke’s edema (n=11), and leukoplakia (n=9). On stroboscopy, the lesion disappeared after surgery, and the amplitude and mucosal wave were symmetrical on both sides of the VFs in all patients. Acoustic parameters and VHI significantly improved after surgery in all patients. However, there was no significant difference between the injection and control group in most of the results.Conclusion There was no significant difference in the results of stroboscopy, acoustic, aerodynamic, and subjective evaluation before and after surgery in the injection group and the control group.
Myofibroblastic sarcoma (MS) is an extremely rare form of head and neck tumor that originates from mesenchymal cells. Myofibroblasts are mesenchymal spindle cells that share the features of fibroblasts and smooth muscle cells. Radiologic examinations such as CT and MRI are useful first-line diagnostic tools for differential diagnosis. Complete surgical excision is recommended for successful treatment. MS can be classified as low, intermediate or high grade considering its histological differentiation and time course. Intermediate and high grade MS are known to be related to local recurrence or distant metastasis. With a review of literature, we report a case of MS arising from the left buccal mucosa in a 56-year-old male who complained of a painless left buccal mass. The patient was successfully treated by margin-free excision and the pathologic findings concluded as intermediate grade without any complication. There was no recurrence observed for two years since the surgery.
Background and Objectives Metabolic syndrome is a medical problem featured by the coexistence of several risk factors such as, heart disease, stroke, and diabetes. The association between metabolic syndrome and incidental paranasal sinusitis has not been definitely proved yet. This study was established to prove if metabolic syndrome might be related to incidental paranasal sinusitis.Subjects and Method Of 5682 patients who had undergone brain MRI for regular checkups between 2011 and 2018 at Kangbuk Samsung Health Care Center, we analyzed 2882 cases with normal sinus and incidental paranasal sinusitis that had been deciphered by specialized radiologists. Data of various components of metabolic syndrome were also used. Multivariable logistic regression analysis was performed to calculate the odds ratio (OR) of having incidental paranasal sinusitis between subjects with metabolic syndrome components and those without.Results Of 2882 patients aged over 18 years (mean age, 51.8±9.47 years; 55.4% male), 353 incidental paranasal sinusitis subjects (232 male with mean age of 51.39±9.27 years and 121 female with mean age of 52.43±9.69 years) were identified. Metabolic syndrome was identified in 554 patients. The adjusted OR of having incidental paranasal sinusitis was 3.03 (95% confidence interval [CI]: 1.58-5.83) in female with metabolic syndrome. In female, the adjusted OR of having incidental paranasal sinusitis was 2.10 (95% CI: 1.20-3.67) in those with low high density lipoprotein (HDL) cholesterol (<50 mg/dL) and 1.83 (95% CI: 1.06-3.16) in those with higher body mass index (BMI) (≥25 kg/m<sup>2</sup>).Conclusion Results of this study suggest that female with metabolic syndrome, low HDL cholesterol, and high BMI have higher risks for incidental paranasal sinusitis.
Myofibrosarcoma is a rare malignant tumor originating from myofibroblasts. It is classified into low-grade, intermediate-grade, and high-grade according to the histological characteristics. High-grade myofibrosarcoma is reported very rarely worldwide, and its recurrence and metastasis are known to be more common. Myofibrosarcoma is diagnosed by histopathologic examination, and its treatment is complete surgical excision. With a review of literature, we report a case of myofibrosarcoma originating from the right masseter muscle in a 73-year-old male patient who complained of a right chin mass for 4 months. The MRI findings revealed a 4.8 cm-sized heterogeneous contrast-enhancing mass in the right masseter muscle with direct invasion into the ipsilateral medial pterygoid muscle and the mandible body. The patient was treated with margin-free surgical excision, including marginal mandibulectomy, and a highgrade myofibrosarcoma was finally diagnosed as the pathologic finding. Adjuvant radiation therapy was performed as a subsequent treatment, and no recurrence has been observed during follow-up for 1 year.
