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.

Rationale:Harlequin syndrome is an extremely rare benign condition characterized by unilateral facial flushing and sweating.Patient concern:An 11-year-old boy presented with complaint of a right neck mass of 1-month duration.Diagnosis:The preoperative diagnosis was neurogenic tumor of vagus nerve or sympathetic nerve.Interventions:We performed right neck mass removal under general anesthesia.Outcomes:We report a case of harlequin syndrome associated with Horner syndrome in an 11-year boy who underwent excision of right neck schwannoma.Lessons:Clinicians should consider the point that harlequin syndrome could occur as a first sign of more serious conditions.

Objectives. This study aimed to compare the outcome of endoscopic and microscopic tympanoplasty.Methods. This was a retrospective comparative study of 73 patients (35 males and 38 females) who underwent type I tympanoplasty at Samsung Medical Center from April to December 2014. The subjects were classified into two groups; endoscopic tympanoplasty (ET, n=25), microscopic tympanoplasty (MT, n=48). Demographic data, perforation size of tympanic membrane at preoperative state, pure tone audiometric results preoperatively and 3 months postoperatively, operation time, sequential postoperative pain scale (NRS-11), and graft success rate were evaluated.Results. The perforation size of the tympanic membrane in ET and MT group was 25.3%±11.7% and 20.1%±11.9%, respectively (P =0.074). Mean operation time of MT (88.9±28.5 minutes) was longer than that of the ET (68.2±22.1 minutes) with a statistical significance (P =0.002). External auditory canal (EAC) width was shorter in the ET group than in the MT group (P =0.011). However, EAC widening was not necessary in the ET group and was performed in 33.3% of patients in the MT group. Graft success rate in the ET and MT group were 100% and 95.8%, respectively; the values were not significantly different (P =0.304). Pre-and postoperative audiometric results including bone and air conduction thresholds and air-bone gap were not significantly different between the groups. In all groups, the postoperative air-bone gap was significantly improved compared to the preoperative air-bone gap. Immediate postoperative pain was similar between the groups. However, pain of 1 day after surgery was significantly less in the ET group. Conclusion.With endoscopic system, minimal invasive tympanoplasty can be possible with similar graft success rate and less pain.

We report a case of methicillin-resistant Staphylococcus aureus (MRSA) otorrhea with impression material of hearing aid in the middle ear. The patient had chronic otitis media in the right ear with sensorineural hearing loss in both ears. The silicone flowed into the middle ear through a tympanic membrane perforation during the process of making an ear mold. Several days after hearing aid fitting, the patient had severe otalgia, intractable otorrhea, aggravated hearing loss, and dizziness. The pus culture and sensitivity test revealed MRSA. After topical treatment using diluted vinegar irrigation and ototopical vancomycin solution, intractable otorrhea was controlled. The infected silicone impression was removed by canal wall-up mastoidectomy, and hearing was saved. We present here a review of the literature regarding silicone impression in the middle ear after hearing aid mold fitting.
