Objective:To investigate clinical features, treatment modality, and outcomes of patients with parotid abscess.Methods:A retrospective chart review was conducted at Chonnam National University Hwasun Hospital January, 2006 to July, 2017.Results:Among 13 patients, 4 patients had immunocompromised disease, and 3 patients had been diagnosed with pre-existing parotid tumor. Patients were treated with empirical intravenous broad-spectrum antibiotics. Among 13 patients, 7 patients (53.8%) had surgical incision, and drainage was conducted. There was no recurrence or death associated with parotid abscess; however, 1 patient with parotid abscess developed facial nerve palsy that persists, despite adequate treatment.Conclusion:After adequate treatment, including antibiotics and surgical drainage, the prognosis of parotid gland is good. In the case of parotid abscess of immunocompromised patients, we suggest rapid surgical procedure for speedy recovery and minimizing adverse effects.

The patients were divided into two groups based on preoperative bone conduction of less than 25dB (n=50) or more than 25dB (n=25). The postoperative improvement of tinnitus in both groups showed statistical significance. Patients whose preoperative air-bone-gap was less than 15dB showed no improvement in postoperative tinnitus using the visual analog scale (p=0.889) and the tinnitus handicap inventory (p=0.802). However, patients whose preoperative air-bone-gap was more than 15dB showed statistically significant improvement in postoperative tinnitus using the visual analog scale (p<0.01) and the tinnitus handicap inventory (p=0.016). Postoperative change in tinnitus showed significance compared with preoperative tinnitus using visual analog scale (p=0.006). However, the correlation between reduction in the visual analog scale score and air-bone-gap (p=0.202) or between reduction in tinnitus handicap inventory score and air-bone-gap (p=0.290) was not significant. We suggest that the preoperative air-bone-gap can be a predictor of tinnitus outcome after tympanoplasty in chronic otitis media with tinnitus.

Surgical morbidity from open reduction and internal fixation (ORIF) of maxillary sinus wall fracture often surpasses the benefits of ORIF. Hence, the authors devised transnasal endoscopic-assisted reduction of maxillary sinus wall fracture (TERM) without internal fixation as a minimally invasive surgery for maxillary sinus wall fracture. The purpose of this study was to investigate the feasibility of TERM in cadavers and patients. Six cadavers were dissected to evaluate the feasibility of TERM. In addition, 20 patients with maxillary sinus wall fractures who underwent TERM in a tertiary hospital from August of 2013 to December of 2015 were enrolled in this study. Demographic factors, type of anesthesia, computed tomography (CT) scans, clinical characteristics of patients, and patient satisfaction with surgery were analyzed. Cadaveric study showed that endoscopic inferior meatus antrostomy is a feasible method of approaching the maxillary sinus wall in cadavers. In addition, counterforce could be applied to the maxillary sinus wall by pushing packed Vaseline-soaked gauze or using a zygomatic process approach via a Gillies incision. Clinical experience revealed that patients experienced good facial contour restoration postoperatively. The extent of fractured bony segments was reduced on postoperative CT without complications. Patient satisfaction with TERM was greater than that with ORIF (p = 0.031). TERM showed its feasibility in both cadaveric study and clinical study. TERM can be a good alternative to ORIF, especially in patients who are reluctant to undergo a facial incision.
