One-Unit Osteotomy to Correct Deviated Bony Dorsum

Objectives@#. A crooked nose is frequently caused by nasal bony vault deviation, and proper management of the bony vault is an integral part of rhinoplasty. Conventional osteotomy to correct a deviated nose favors simultaneous medial and lateral osteotomies, which allows the free independent movement of each nasal bone. However, patient satisfaction with deviated nose surgery is sometimes low. In the present study, we introduce a one-unit osteotomy procedure that combines bilateral and root osteotomies with unilateral triangular bony wedge resection to allow symmetry of both nasal bones. @*Methods@#. Twenty consecutive patients who presented with bony vault deviation and underwent one-unit osteotomy were enrolled in this retrospective single-center study. The Nasal Obstruction Symptom Evaluation (NOSE) questionnaire was used to evaluate each patient’s functional outcome. The angle of bony vault deviation before and after one-unit osteotomy was measured using a protractor and compared with the results of 14 patients who had undergone conventional osteotomy. The improvement in dorsal deviation was evaluated using facial photography preoperatively and 3 months postoperatively. @*Results@#. NOSE values improved from 8.4±6.4 to 4.1±4.2 (P =0.021). The angle of bony vault deviation improved from 6.9°±2.2° to 2.1°±1.2° (P <0.001) in one-unit osteotomy and from 7.3°±4.0° to 2.7°±1.2° (P =0.001) in conventional osteotomy. The preoperative deviation angle improved by 70.3% in one-unit osteotomy compared with 56.6% in conventional osteotomy, which was a significant difference (P =0.033). The mean grade of the postoperative esthetic outcomes for the remaining deviation was 1.6±0.5, which was similar to that in the conventional osteotomy group. @*Conclusion@#. One-unit osteotomy is a relatively simple procedure that balances the width of both lateral walls by removing excessive bony fragments from the wider bony wall and providing better structural integrity. This technique improves functional outcomes and has equivalent esthetic results to those of the traditional procedure.

A Case of Petrous Apex Meningocele: Unusual Presentation of Cerebrospinal Fluid Leak Following Adenoidectomy

Cerebrospinal fluid (CSF) leak is possible and can be a cause of recurrent bacterial meningitis. Petrous apex meningocele (PAM) is mostly asymptomatic and is often found during incidental imaging tests. We experienced a case of CSF rhinorrhea with recurrent meningitis in bilateral PAM after adenoidectomy. This report highlights the diagnostic process of CSF leak, identification of leakage site, and surgical approach to petrous apex lesions.

Minimally Invasive Transcanal Removal of Attic Cholesteatoma / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: In treating attic cholesteatoma, traditional microscopic approach provides limited exposure to the attic space. Recently, the use of endoscope has emerged as a new treatment option for attic cholesteatoma. The aim of this study is to report the preliminary results of transcanal endoscopic removal of attic cholesteatoma and to evaluate the feasibility of endoscopic approach to attic cholesteatoma. SUBJECTS AND METHOD: Six patients with attic cholesteatoma were enrolled in this study from Sep 2014 to Oct 2015. Cholesteatoma was removed via transcanal endoscopic approach. We analyzed the clinical characteristics, surgical management and treatment outcomes. RESULTS: All patients had attic cholesteatoma in the epitympanic space with scutum erosion. However, the disease was restricted to the epitympanic space in three patients, whereas a limited extension of cholesteatoma to the aditus ad antrum was observed in two patients, and mesotympanum was involved in the remaining one patient. All of the patients suffered from conductive or mixed hearing loss with mean air-bone gap of 17.4 dB, and underwent endoscopic transcanal removal of cholesteatoma and scutoplasty. In three patients, the incus and malleus head were removed due to ossicular erosion, and a second-stage ossicular reconstruction was planned. No residual or recurrent diseases were noted during the follow-up period (mean: 13 months). No surgical complications were observed postoperatively, and favorable hearing outcome was obtained in all patients. CONCLUSION: Transcanal endoscopic approach was successfully performed in patients with limited attic cholesteatoma. Further studies involving a large number of patients with long-term follow-ups are necessary to prove the clinical efficacy of transcanal endoscopic approach in managing limited attic cholesteatoma.

Clinical Characteristics of Sphenoid Sinus Fungal Ball Patients With Visual Disturbance

OBJECTIVES: A sphenoid sinus fungal ball is a rare disease that can cause visual disturbances. Most afflicted patients remain in an indolent state. However, once the visual disturbance has occurred, the recovery rate is very low. The purpose of this study was to overview the clinical characteristics of patients with a sphenoid sinus fungal ball and ascertain factors possibly related to the occurrence of a visual disturbance. METHODS: We retrospectively reviewed the medical records of all patients who underwent endoscopic sinus surgery for a sphenoid sinus fungal ball at our hospital. We enrolled 47 patients in this study. RESULTS: Old age and a female predominance were noted. Nasal symptoms were the most common symptom. Eight patients showed visual disturbances. We also compared the clinical characteristics between patients with and without visual disturbances in univariate analysis. Old age, underlying diabetes mellitus, and a sphenoid sinus wall defect visible by computed tomography were factors significantly related to the occurrence of visual disturbances. But only sphenoid sinus wall defect showed significance in multivariate analysis. CONCLUSION: It is important to prevent complications, such as visual disturbance, in patients with a sphenoid sinus fungal ball. This study describes an early surgical treatment that may be required for patients with a sphenoid sinus fungal ball and particularly patients with a sphenoid sinus wall defect.

A Case of Metachronous Human Papilloma Virus-Associated Squamous Cell Carcinomas in Head and Neck / 대한이비인후과학회지

Synchronous or metachronous head and neck cancer is known to occur in up to 20% of patients, negatively affecting long-term prognosis. We experienced a case of metachronous head and neck cancers in a Human papillomavirus (HPV)-positive patient without a history of smoking, initially presenting with as a cancer of unknown primary (CUP), and then with a contralateral tonsil cancer with metastatic lymphadenopathy five years later. This report highlights the clinical usefulness of HPV typing to determine the optimal extent of surgery and the follow-up strategy in CUP.

Central Skull Base Osteomyelitis: 10-Case Series in a Single Center / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Skull base osteomyelitis (SBO) typically evolves as a complication of malignant otitis externa (MOE) in diabetic patients and involves the temporal bone. Central SBO (CSBO), which mainly involves the sphenoid or occipital bones, has clinicaland radiological characteristics similar to those of SBO but without coexisting MOE. We investigated a group of patients with CSBO and studied the clinical course of CSBO. SUBJECTS AND METHOD: Medical records of patients who were diagnosed with CSBO were retrospectively analyzed from 1999 to 2014. RESULTS: Ten patients (mean age; 60.5 years) were identified. There were five males and five females. All patients suffered from headache, and six patients had cranial nerve palsy including oculomotor (20%), abducens (10%), vestibulocochlear (10%), glossopharyngeal (20%), vagus (30%) and hypoglossal (10%) nerve. Patients had underlying diseases including diabetes mellitus (40%), immunosuppression status after liver transplantation (10%) and cardiovascular disease (40%). Four patients received endoscopic biopsy and debridement for diagnostic and curative intent. Patients were treated with intravenous antibiotics for 5.1 weeks in average and oral antibiotics for 17 weeks. Mean follow-up period was 12.4 months and the mortality rate was zero. 40% of patients had residual neurologic deficit. The earliest sign of improving CSBO was headache (mean; 3.1 weeks) and the erythrocyte sedimentation rate was the latest improving sign (mean; 4 months). CONCLUSION: CSBO was diagnostic and therapeutic challenge to the clinicians. The timely diagnosis and long-term antibiotics therapy could avoid a mortality case and minimize the permanent neurologic deficit.
