Trauma, congenital malformation and aging process can be a cause of the deviation of laryngeal prominence in the thyroid cartilage. Among these, the senility is the most common cause. Usually, ossification in the thyroid cartilage has occurred symmetrically, but the asymmetrical event leads to the shift of laryngeal prominence. Also, such deformity can provoke protrusion of false vocal fold. A 75-year-old man with hoarseness and globus sense in throat visited our clinic. Five years ago, he experienced a blunt trauma on left midline neck and had a concave deformity in the left thyroid cartilage lamina. Laryngoscopic findings revealed a marked protrusion in the left false vocal fold. We performed the laryngeal microsurgery to discriminate the tumorous condition. The pathology revealed non-pathologic mucosa. We report a unique and didactic case with a brief literature review.

Chronic irritation to arterial wall by foreign material may give rise to delayed vascular injury. A 50 years old male patient with kyphoscoliosis had undergone fixation of orthopedic Cotrel-Dubousset(CD) rods and screws. Fourteen months after that surgery, a false aneurysm of the descending thoracic aorta associated with pulsating hematoma in the muscular chest wall developed. The false aneurysm was managed by resecting the diseased aortic segment and replacing the vascular graft.

This study compared voice range profiles (VRPs) of modal and falsetto register in 53 dysphonic and 53 non-dysphonic adult women with gliding vowel /a/'. The results shows that maximum fundamental frequency (F0_MAX), maximum intensity (I_MAX), F0 range (F0_RANGE), and intensity range (I_RANGE) are lower in the dysphonic group than in the non-dysphonic group. F0_MAX and F0_RANGE are significantly higher in falsetto register than modal register in both groups. I_MAX and I_RANGE are significantly higher in falsetto register in the non-dysphonic group, but those are not different between two registers in the dysphonic group. There was no statistically significant difference in minimum F0 (F0_MIN) and minimum intensity (I_MIN) between the two groups. Modal-falsetto register transition occurred at 378.86 Hz (F4#) in the dysphonic group and 557.79 Hz (C5#) in the non-dysphonic group, which was significantly lower in the dysphonic group. It can be seen that both modal and falsetto registers in dysphonic adult women are reduced compared to non-dysphoinc adult women, indicating that the vocal folds of dysphonic adult women are not easy to vibrate in high pitches. The results of this study would be the basic data for understanding the acoustic features of voice disorders.

Schwannoma is a benign well-encapsulated tumors arising from the sheath of Schwann cell of the peripheral motors, sensory, and cranial nerves, but not from the optic and olfactory nerves. Since it is relatively common in the head and neck region, it should be included in the differential diagnosis of head and neck tumor. However, reports of laryngeal involvement have rarely appeared in the literature. We have experienced a 50-year old woman and 39-year old woman with history of progressive voice change. We recognized a benign mass at the false cord area with the telelaryngoscope and CT. The tumors were successfully removed by transoral CO2 laser resection without tracheotomy.

Background and Objectives : Vocal abuse and misuse and muscle tension dysphonia that have various movements of false vocal folds may be related to the development of benign vocal folds lesions, such as vocal nodules, polyps, and cysts. This study was designed to determine whether benign vocal folds lesions were related with movements of false vocal folds on phonation. Material and Methods : One Hundred and seventy eight subjects were studied. All subjects received otolaryngological evaluation including videostroboscopy, objective voice measures. Patients were diagnosed as normal shape of vocal folds (group a), approximation of bilateral false vocal folds (group b), approximation of unilateral false vocal folds (group c), lateralized extension of false vocal folds (group d), and medialized approximation of posterior false vocal folds (group e). We analyzed the results of benign vocal folds lesions in each group. Results : Differences were found between the normal shaped group and the abnormal shaped group. No differences were found between each abnormal groups except group d and e. Conclusion : The shape of false vocal folds was related to the benign vocal folds lesions.

Pseudoaneurysm of the thoracic aorta is potentially fatal. However, reports of such cases are rare even in large series. We report four cases of thoracic aortic pseudoaneurysm who underwent surgical repair, The causes were considered as infection in two cases (VSD repair, descending thoracic aortic aneurysm resection) and blunt chest trauma by traffic accident in two patients. The pseudoaneurysms developed on ascending aorta suspected as sites of arterial and cardiolplegic needle insertion in one patient. The others were located at descending thoracic aorta immediatly below the left subclavian artery. One patient died of sepsis associated with bile peritonitis and others were followed up from 10 to 18 months with specific morbidity. This study suggest that the incidence of pseudoaneurysm of the thoracic aorta followed by open heart or aorctic surgery can be repaired succesfuly and careful inspection of associated injury is very important in cases of traumatic thoracic pseudoaneurysm.

False vocal fold hypertrophy caused by diverse pathologic lesion, such as laryngeal amyloidosis, laryngeal lipidosis, laryngocele, saccular cyst and sulcus vocalis. False vocal fold hypertrophy, however, is also caused laryngeal structure deformity, irrespective of pathologic lesions. In this article, we report some cases of false vocal fold hypertrophy caused by inward bowing of thyroid cartilage. At the clinic of the department of otorhinolaryngology in Gangnam Severance Hospital, with 3 male complained of hoarseness as subjects, and comfirmed of false vocal fold hypertrophy using the stroboscopy and larynx CT we checked vocal fold and laryngeal structure. Three patients with apparent hypertrophy of false vocal fold were investigated with computerized tomography (CT). In all patients, marked concavity of thyroid cartilage was revealed in CT scan at the level of the false vocal fold, and this deformity of the thyroid cartilage seemed to cause a protrusion of false vocal fold which taken as hypertrophy in stroboscopy. Careful palpation of the larynx and a CT scan taken at the level of the false vocal fold should be useful in determining whether hypertrophy of the false vocal fold is pathologic. For the next articles, It is necessary to discuss for the cause, diagnosis, treatment and prevention of inward bowing of thyroid cartilage.

Background: The purpose of this study was to explore the mediating effect of ambivalence over emotional expressiveness on the relationship between covert narcissistic tendency of adults in their twenties and the satisfaction of interpersonal relations. Methods: 194 male and female adults in their twenties completed the self-report questionnaires on covert narcissism, ambivalence over emotional expressiveness, and interpersonal satisfaction. A mediated model was tested using the SPSS Macro by Hayes. Results: We verified that the ambivalence over emotional expressiveness played a mediating role in the relationship between covert narcissistic tendency and interpersonal satisfaction. In terms of the characteristics of relationship, except for the superior person, the relationship between lover/spouse and friends/colleagues showed the mediating effect between covert narcissism and interpersonal satisfaction. Conclusions: The covert narcissistic tendency itself affects low interpersonal satisfaction, but the ambivalence over emotional expressiveness affects low interpersonal satisfaction when the covert narcissist interacts with lover/spouse, friends/colleagues. We discussed the directions of intervention for the covert narcissist having low satisfaction in relationships, limitations and future suggestions of this research.
