Correction of Tilted Cartilaginous Nasal Dorsum with Clocking Suture Single Technique / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Deviated nose is a commonly encountered deformity, and the correction of deviated nose is the most difficult part of septorhinoplasty. Generally, additional cartilaginous graft is required for straightening the deviated segment. However, there are many cases where sufficient cartilage grafts are not available due to revision surgery or cases with small cartilage. In such cases, tilted cartilaginous dorsum should be corrected without grafting. The purpose of this study is to evaluate the usefulness of clocking suture single technique for cartilaginous deviation by analyzing the surgical results of cases who underwent corrective rhinoplasty without any cartilaginous graft. SUBJECTS AND METHOD: From June 2009 to June 2016, 43 patients with tilted cartilaginous dorsum were corrected with clocking suture single technique. Cases underwent additional graft for straightening dorsum were excluded. The patients' medical records and facial photographs were analyzed to assess surgical outcomes and complications. Surgical outcomes were graded as excellent, fair and poor according to patients' satisfaction and evaluation by two physicians. RESULTS: Mean follow up period was 15.4 (5-39) months. There were 39 patients (90.7%) with excellent result, 3 patients (7.0%) with fair results, and 1 patient (2.3%) with poor result. Augmentation was performed with expanded polytetrafluoroethylene or septal cartilage in 26 patients (60.5%) and dorsal hump was removed in 22 patients (51.2%). Concomitant augmentation didn't affect surgical results. No postoperative complication such as infection or inflammation were found. CONCLUSION: The clocking suture single technique is an effective surgical method for the correction of dorsal cartilaginous deviation.

The Anatomical Relationship between the Anterior Ethmoid Artery, Frontal Sinus, and Intervening Air Cells; Can the Artery Be Useful Landmark? / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: The anatomy surrounding the frontal sinus (FS) and the anterior ethmoid artery (AEA) is variable and complex. We tried to determine the value of AEA as a landmark for finding FS during endoscopic sinus surgery. SUBJECTS AND METHOD: Using the high-resolution CT scans of coronal and sagittal reconstruction, the distance between AEA and FS (D-AF) and the number and type of intervening cells between these two structures were investigated. Next, the distance between AEA and the anterior skull base (D-AS) was measured and the correlation between D-AF and D-AS was analyzed. RESULTS: A total of 119 nasal cavities from 70 subjects was analyzed. Of these analyzed, AEA was located just behind the frontal recess in only 17 nasal cavities (14%) and one or two intervening cells were located between FS and AEA in the remaining 86% of the nasal cavities. The most frequent type of intervening cells was supra bullar cell, followed by supraorbital and frontal bullar cells. The mean D-AF and D-AS measurements were 8.58+/-5.56 mm (0-22.6 mm) and 1.65+/-1.90 mm (0-6.7 mm), respectively. D-AS was not significantly correlated with the distance between the FS and AEA (p=0.433), therefore, D-AS could not be predicted. CONCLUSION: The relationship between FS and AEA was non-predictable, and in most cases, there were one or two intervening cells between FS and AEA. Therefore a thorough review of thin section CT scans is necessary.

A Case of Squamous Cell Carcinoma Arising in a Second Branchial Cleft Cyst / 대한이비인후과학회지

The existence of primary brancial cleft cyst carcinoma is controversial since first described by Volkmann in 1882. Martin and Khafif proposed criteria for diagnosis of primary branchiogenic carcinoma, which are now widely accepted in the literature. The most important criterion is the presence of squamous cell carcinoma arising from the benign squamous epithelium of branchial cleft cyst. We report a case of a 69-year-old man with branchial cleft cyst carcinoma, which was suspected to be cervical lymph node metastases from an unknown primary tumor. The subject underwent a surgical operation, and postoperative pathologic findings revealed a squamous cell carcinoma developing in the stratified squamous epithelial lining of the branchial cleft cyst. This case meets the criteria established by Martin and Khafif, thus we present it with a review of literature.
