RESUMO

To correct an Asian short nose with low dorsum, short columella, and poorly defined nose tip, augmentation rhinoplasty has been popularized. A simple augmentation no longer is considered an efficient rhinoplasty approach for Asians aesthetically; most surgeons simultaneously perform nasal elongation and augmentation during rhinoplasty. To extend the nose length successfully, important factors are cartilages, mucosal and skin conditions, and presence and degree of fibrotic changes. In addition, surgeons should consider preoperatively how much should be extended from an aesthetics perspective. This article introduces the current practice of surgical correction of the short nose in Asians.

RESUMO

BACKGROUND: To resolve nasal obstruction in rhinoplasty, inferior turbinate outfracture is performed widely alone or combined with other procedures. There are conflicting reports on the effect of inferior turbinate outfracture. This study evaluated the persistence of morphologic changes after inferior turbinate outfracture. METHODS: This retrospective study enrolled 55 patients who underwent inferior turbinate outfracture without septal surgery to approach the sphenoid sinus for brain tumor removal. Coronal paranasal sinus computed tomographic images obtained preoperatively and 6 months postoperatively were compared. The authors measured the shortest distance from the median line to the medial border of the conchal bone and the shortest distance from the medial border of the conchal bone to the lateral nasal line. The authors also gauged the projection angle of the conchal bone and constitutional thickness of the inferior turbinate. RESULTS: After inferior turbinate outfracture, the shortest distance from the median line to the medial border of the conchal bone increased, and shortest distance from the medial border of the conchal bone to the lateral nasal line decreased. The projection angle decreased significantly by 6 months postoperatively. After outfracture, the thickness of the medial mucosa had increased significantly, wheras the thickness of the conchal bone had decreased significantly (p < 0.05). CONCLUSIONS: The effect of inferior turbinate outfracture is preserved for at least 6 months. Moreover, compensatory hypertrophy of the medial mucosa develops in the inferior turbinate after outfracture. Therefore, outfracture with medial submucosal volume reduction would be recommended as the best procedure for treating inferior turbinate hypertrophy. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

RESUMO

OBJECTIVE: To investigate the effects of acute noise stress on two amine stress hormones, norepinephrine (NE) and 5-hydroxyindoleacetic acid (5-HIAA) in the brain and plasma of mice after noise exposure. METHODS: Mice were grouped into the control and noise groups. Mice in the noise group were exposed to white noise of 110dB sound pressure level for 60min. Auditory brainstem response thresholds, distortion product otoacoustic emissions, the organ of Corti grading scores, western blots of NE/5-HIAA in the whole brain and hippocampus, and the plasma levels of NE/5-HIAA were compared between the two groups. RESULTS: Significant hearing loss and cochlear damage were demonstrated in the noise group. NE and 5-HIAA in the hippocampus were elevated in the noise group (p=0.019/0.022 for NE/5-HIAA vs. the control). Plasma levels of NE and 5-HIAA were not statistically different between the groups (p=0.052/0.671 for NE/5-HIAA). CONCLUSION: Hearing loss with outer hair cell dysfunction and morphological changes of the organ of Corti after noise exposure in C57BL/6 mice proved the reliability of our animal model as an acute noise stress model. NE and 5-HIAA are suggested to be the potential biomarkers for acute noise stress in the hippocampus.

RESUMO

Temporalis fascia has been used widely as a interposition graft for mucosal rotation flap in nasal septal perforation repair. However, the exact role of temporalis fascia in healing process has not yet been clarified. For the pedicle of rotation flap has been considered as a major vehicle for nutrition distribution, the role of temporalis fascia has been devaluated. In this study, we experienced small nasal septal perforation repairs using free mucosal graft not having pedicles but covered by temporalis fascia. Three patients with small nasal septal perforations not larger than 1 × 1 cm were included. In 2 patients, the perforations were repaired using free composite grafts from the inferior turbinate mucosa covered by continuous temporalis fascia not divided, and the surgical results were successful with complete healings. In 1 patient, however, the temporalis fascia was divided into 2 parts to better fit the shape of the perforation, and the graft failed to survive. These surgical results suggest that the temporalis fascia might have an important role in healing process of nasal septal defect and could be used as a beneficial options for small mucosal defect repair surgeries using free mucosal grafts.

RESUMO

Hemangioma is one of the most common benign neoplasm involved on head and neck. However, cavernous hemangiomas are relatively rare in preauricular sinus space and has rarely been reported around the world. Recently, a 44-year-old female patient came to our clinic with cavernous hemangioma involving the preauricular sinus. This case was surgically managed via excision. Preoperatively, it was difficult to differentiate the mass of hemangioma clinically and diagnostically from a preauricular fistula, a salivary gland tumor, or an enchondroma. This case report describes the subcutaneous hemangioma on a preauricular sinus, which is rarely seen in Korea. The clinical presentation and management are discussed with a review of the literature.

RESUMO

OBJECTIVES/HYPOTHESIS: Forceful eyelid closure syndrome (FECS) was first reported at the Proceedings of the Second International Tinnitus Seminar in 1983. The main symptom of this syndrome is a spontaneous muscular tinnitus related only to forced eye closure, specifically the voluntary contraction of the periorbital muscles. Although investigation of the syndrome was initiated >100 years ago, only four cases have been published in the past 20 years. We report six cases of middle ear myoclonus tinnitus diagnosed as FECS in children and discuss issues surrounding the diagnosis and treatment of this syndrome. STUDY DESIGN: Retrospective case series. METHODS: From 2009 to 2011, six children complaining of clicking or crackling sounds in their ears presented at Seoul St. Mary's Hospital. Endoscopic examination and recording of the tympanic membrane were performed while the patients were asked to close their eyes forcefully. Audiologic studies including acoustic reflex decay and static compliance were performed for documentation of the movement of the tympanic membrane. Triggering factors of FECS in the children were carefully evaluated. RESULTS: Synchronous movement of the tympanic membrane in response to forced eye closure on endoscopic examination was the most reliable finding to diagnose FECS. Acoustic reflex decay and other impedance audiogram findings showed irregular perturbations during forced eye closure, which led to diagnosis of the tinnitus as middle ear myoclonus. Most of the patients had triggering factors for FECS. Reassurance and removal of the triggering or causal factors with or without medication improved clicking sounds coming from middle ear myoclonus. CONCLUSIONS: FECS is a rare clinical entity and can be easily missed in routine clinical examination. We suggest that patients, especially children, with clicking or crackling tinnitus should be evaluated for FECS using proper diagnostic tools. A possible mechanism of FECS in children postulated from our case review is suggested.

RESUMO

BACKGROUND AND OBJECTIVES: Differences in morphology of auricular keloids possibly contribute to distinct results of treatment. The aim of this study was to evaluate clinical characteristics of the auricular keloids according to the modified Chang-Park classification and to compare the results of treatment including recurrence rate between the subgroups. SUBJECTS AND METHODS: Clinical data of 15 patients of auricular keloids were retrospectively reviewed. The keloids were classified according to modified Chang-Park classification. Clinical characteristics, the presence of recurrence, and the duration required for the recurrence were compared. RESULTS: Eight out of 15 patients (53.3%) were single sessile type (type II), followed by 4 patients of pedunculated type, 1 patient of multiple sessile type, 1 patient of buried type, and 1 patient of mixed type, respectively. Recurrent keloids after previous surgeries were noted in 7 out of 15 patients and most of them (6 of 7, 85.7%) were sessile type. Three patients who underwent surgery at our department showed recurrence. CONCLUSIONS: The classification of auricular keloids according to morphologic patterns can assist surgeons in choosing the appropriate management.
