RESUMEN
Objectives: Osteomas in the external auditory canal (EAC) can lead to stenosis, and impair epithelium migration and self-cleaning capability, thereby trapping keratinized epithelium and triggering the development of cholesteatoma. Our study aims to identify the risk of cholesteatoma development in patients with osteoma and proposes a stepwise approach to managing patients with EAC osteoma. Methods: The maximum diameter of the osteoma was measured in axial and coronal views on high-resolution computed tomography (HRCT). We calculated the relative obstruction ratio caused by the osteoma in the axial and coronal views. Prior to surgery, otoscopy was employed to identify pedicle formation. The patients were categorized into 2 groups based on the presence of cholesteatoma. Results: We identified 43 patients diagnosed with EAC osteoma. A total of 9 (20.9%) patients with EAC osteomas developed cholesteatoma and the other 34 (79.1%) did not. The maximum diameter of osteomas with and without cholesteatoma was 12.67 ± 4.09 and 7.67 ± 3.27 mm, respectively (P < .001). In the group without cholesteatoma, 21 osteomas had pedicles while the other 13 did not. In the cholesteatoma group, 2 osteomas had pedicles and 7 did not (P = .037). No difference was observed in the relative obstruction ratio between these 2 groups. Conclusions: Our findings indicate that larger osteomas are more likely to develop cholesteatoma, while the formation of a pedicle may reduce the occurrence of cholesteatoma. In symptomatic patients, preoperative evaluation, including HRCT and otoscopy, is vital for assessing the extent of the osteoma and the potential coexistence of cholesteatoma. These factors are critical for preoperative consultations and surgical planning.
RESUMEN
Background and Objectives: Cervical space infection could also extend to the mediastinum due to the anatomical vicinity. The mortality rate of descending necrotizing mediastinitis is 85% if untreated. The aim of this study was to identify risk factors for the progression of deep neck abscesses to descending necrotizing mediastinitis. Materials and Methods: We retrospectively reviewed the medical records of patients undergoing surgical treatment of deep neck abscesses from August 2017 to July 2022. Computed tomography (CT) was performed in all patients. Before surgery, lab data including hemoglobulin (Hb), white blood cell count, neutrophil percentage, C-reactive protein (CRP) level, and blood glucose were recorded. Patients' characteristics including gender, age, etiology, and presenting symptoms were collected. Hospitalization duration and bacterial cultures from the wound were also analyzed. Results: The C-reactive protein (CRP) level was higher in patients with a mediastinal abscess than in patients without a mediastinal abscess (340.9 ± 33.0 mg/L vs. 190.1 ± 72.7 mg/L) (p = 0.000). The submandibular space was more commonly affected in patients without a mediastinal abscess (p = 0.048). The retropharyngeal (p = 0.003) and anterior visceral (p = 0.006) spaces were more commonly affected in patients with a mediastinal abscess. Conclusions: Descending necrtotizing mediastinitis results in mortality and longer hospitalization times. Early detection of a mediastinal abscess on CT is crucial for treatment. Excluding abscesses of the anterior superior mediastinum for which transcervical drainage is sufficient, other mediastinal abscesses require multimodal treatment including ENT and thoracic surgery to achieve a good outcome.

BACKGROUND: Idiopathic sudden sensorineural hearing loss (ISSNHL) presents with emergent hearing impairment and is mainly treated with steroids. However, limited data exist regarding the prognostic factors among elderly patients (>65 years old) who receive an intra-tympanic steroid injection (ITSI). Therefore, we investigated the prognostic factors in these patients. METHODS: Between July 2016 and March 2022, we retrospectively enrolled 105 elderly patients (>65 years old) with unilateral ISSNHL who were treated with an ITSI, and recorded their clinical and audiological variables. RESULTS: The patients had a mean age of 72.03 ± 6.33 years and mean hearing level gain of 22.86 ± 21.84 dB, speech reception threshold (SRT) gain of 15.77 ± 35.27 dB, and speech discrimination score (SDS) gain of 19.54 ± 27.81 %. According to Siegel's criteria, 5 (4.76 %), 44 (41.91 %), 46 (43.81 %), and 10 (9.52 %) patients had complete recovery, partial recovery, slight improvement, and no improvement, respectively. In the univariate analysis, vertigo (odds ratio [OR] = 0.290, 95 % confidence interval [CI]: 0.130-0.651, p = 0.002) and profound hearing loss on pure tone audiometry (PTA; OR = 0.233, 95 % CI: 0.101-0.536, p = 0.004) were negative prognostic factors among elderly ISSNHL patients. In the multivariate analysis, vertigo (OR = 0.300, 95 % CI: 0.128-0.705, p = 0.005) and profound pure tone audiometry (OR = 0.240, 95 % CI: 0.101-0.570, p = 0.001) were independent adverse prognostic factors among elderly ISSNHL patients. CONCLUSIONS: We demonstrated the treatment outcomes of 105 elderly ISSNHL patients after an ITSI. Vertigo and profound PTA are independent adverse risk factors among elderly ISSNHL patients, and patients with these risk factors require active treatment.

BACKGROUND: The prevalence of adult cochlear implant (CI) surgery is increasing. However, the relevant adult CI data in Taiwan are insufficient due to the relatively small number of adult implant patients. The two main factors hindering adult implantation are the high cost of the surgery itself and inadequate knowledge regarding the effectiveness of CI for hearing and suppression of tinnitus. Here, we present data regarding adult CI outcomes from a single tertiary hospital. METHODS: A total of 116 consecutive adult CI recipients (≥18 years old) who completed at least 12 months of speech perception tests (words and sentences) between January 1999 and December 2020 were enrolled in this retrospective population-based cohort study. Thirty patients completed speech perception (words and sentences) testing as well as three questionnaires relating to quality of life, and 71 completed full tinnitus suppression studies. Subjects' pre- and post-CI questionnaires were evaluated to assess overall CI outcome. RESULTS: For auditory evaluation, the scores of easy sentences (ES), difficult sentences (DS), and phonetically balanced (PB) word recognition tests reached a plateau at 3 months post-CI (p = 0.005, 0.001, and 0.004, respectively) in most subjects. The post-CI scores of bodily pain, mental health, and social role functioning were significantly higher than corresponding pre-CI scores on the SF-36 Health Survey-Taiwan version (p = 0.036, 0.019, and 0.002, respectively). Furthermore, the post-CI scores of basic sound perception, speech production, and advanced sound perception were significantly higher than the corresponding pre-CI scores on the Nijmegen Cochlear Implant Questionnaire (p < 0.001, 0.013, and <0.001, respectively). Self-esteem was significantly correlated with the Categories of Auditory Performance scale and Speech Intelligibility Rating scale at 3, 6, and 9 months post-CI. CI improved tinnitus in approximately 65.1% of 71 adults. Based on the Tinnitus Handicap Inventory, 66.7% of patients were in grade 3-5 before surgery. However, after CI, only 34.4% of patients remained in THI grade 3-5. CONCLUSION: This study confirmed that CI can improve speech perception (words and sentences), physical health, mental health, social interaction, and self-esteem in adult patients with profound hearing loss. CI also significantly alleviated tinnitus. The outcomes of ES, DS, and PB tests at 3 months post-CI were non-inferior to other longer post-CI periods and could be utilized as references for recovery and evaluation of prognosis.

BACKGROUND: Otitis media with effusion (OME) is a condition where non-infective fluid builds up in the middle ear. Long-term OME can cause damage to the middle ear and hearing impairment. Ventilation tube insertion (VTI) is an efficient procedure to drain persistent OME. However, the effect of prophylactic ear drops after VTI remains controversial because no infection is present. This study investigated the need for and effect of quinolone ear drops in patients with OME after VTI. METHODS: Between July 2018 and July 2021, 272 patients (436 ears with OME) who underwent VTI were enrolled. Prophylactic quinolone ear drops (ofloxacin) were used in 271 OME ears and not used in 165. The clinical findings and effect of the ear drops were assessed. RESULTS: The group with postoperative ofloxacin had less postoperative otorrhea (p < 0.001). In univariate analysis, age ≥ 13 years (odds ratio [OR] = 1.499, 95% confidence interval [CI]: 1.003-2.238, p = 0.046) was significantly associated with recovery to normal middle ear functioning (type A on postoperative tympanometry). No adenoid hypertrophy (OR = 1.692, 95% CI: 1.108-2.585, p = 0.014) and no postoperative otorrhea (OR = 2.816, 95% CI: 1.869-4.237, p < 0.001) were significant independent factors associated with middle ear recovery in both univariate and multivariate analysis. After VTI, 65% of tympanic membranes in the group with postoperative ofloxacin recovered to normal, while in 67% of tympanic membranes in the group without ofloxacin scarring remained. CONCLUSIONS: Patients who received prophylactic postoperative ofloxacin had less postoperative otorrhea. No adenoid hypertrophy and no postoperative otorrhea were significant independent predictors of middle ear recovery to normal function in both univariate analysis and multivariate analysis. However, prophylactic ofloxacin was not an independent predictor of normal middle ear functioning after VTI. After VTI, most OME patients who had used ofloxacin postoperatively had eardrums that were in better condition than those of patients who had not used ofloxacin. In this study, we confirmed the advantages and limitations of OME after VTI with prophylactic ofloxacin, thus providing clinicians with some guidance regarding the decision to administer prophylactic ofloxacin.

PURPOSE: Auricular pseudocyst (AP) is a benign, noninflammatory swelling to the ear, located on either the front or side surface. Deroofing surgery with variable compression methods is considered the most effective method. However, post-operative wound pain is the main drawback following compression. We are introducing a novel painless surgical procedure which involves deroofing technique followed by Merocel® compression dressing. METHODS: From 2015 to 2020, thirty-one patients with AP received this new surgical compression method in our university-affiliated tertiary hospital. Retrospective chart review and the analysis of the results were conducted. RESULTS: All patients had unilateral lesions, with left side lesions (58.1%) predominant. The concha cymba (38.7%) and concha cavum (35.8%) were the most common sites. Previous aspiration or drainage had been performed for the cysts in eight patients (25.8%). Only one patient had the recurrence after post-operative 3 months and received the revised surgery without following recurrence and discomfort. Among all patients, 29 (93.5%) patients claimed minimal pain around 0 or 1 in numeric rating scale of pain score. Three patients had mild ecchymosis but recovered after conservative treatment. One patient had mild auricular deformity after surgery due to pre-treatment partial cartilage necrosis. All patients had follow-up for at least 6 months. CONCLUSION: This novel Merocel® compression dressing technique to treat AP after deroofing is an effective procedure. Minimal pain, simple to do and easily acquired materials were the advantages of this novel procedure.

PURPOSE: The purpose of this study was to measure the incidence of complications in sudden sensorineural hearing loss (SSNHL) patients treated with intra-tympanic steroid injection (ITSI) and compare hearing recovery rates. MATERIALS AND METHODS: 123 patients with unilateral SSNHL receiving ITSIs were included in this study. Post-ITSI complications were documented including otalgia, dysgeusia, vertigo (duration>1 h), and persistent eardrum perforation. The pain intensity was evaluated with visual analog scale (VAS). Hearing was measured before ITSI and at 1 month after the final ITSI. We compared our patients' hearing threshold between presence and absence of different complications. RESULTS: 47.2% patients experienced post-injection otalgia with the average VAS score 3.2 (range 2-6). Five (4.1%) and six (4.9%) patients exhibited vertigo and persistent eardrum perforations, respectively. The patients were divided into three groups based on the absence of complications and the presence of vertigo and eardrum perforation. The hearing threshold improvements did not differ significantly among the three groups (p = 0.366). Although the difference was not significant (p = 0.664), the proportion of patients experiencing post-ITSI vertigo who were on contemporaneous oral steroids was lower than the proportion of non-vertigo patients on such steroids. CONCLUSION: The incidences of otalgia, vertigo, and persistent eardrum perforation in SSNHL patients treated with ITSI were 47.2%, 4.1% and 4.9%, respectively. We found no association between concurrent oral steroid use and the incidence of post-ITSI eardrum perforation or vertigo. Although statistical significance was lacking, patients who did not take contemporaneous oral steroids may have a higher rate of prolonged post-ITSI vertigo.

BACKGROUND: Fibrous dysplasia (FD) is a benign, slowly progressive disease resulting from the replacement of normal bone by fibro-osseous tissue. The incidence of craniofacial involvement of FD is as high as 23%. Sinonasal involvement of FD may lead to obstruction of the natural sinus ostium, resulting in acute sinusitis. We present a rare case of sinonasal FD complicated by subperiosteal abscess that was removed by bicoronal incision and frontal-basal approach in the second surgery. CASE DESCRIPTION: A 16-year-old male patient presented with painful swelling on his left eye that had persisted for 2 days. Transnasal endoscopic drainage of the left orbital subperiosteal abscess was performed and progressive improvement of the swelling of the left eye was noted. After the acute phase, transcranial removal of the sinonasal bony lesion and mesh reconstruction of the left orbital wall were performed. There has been no progression of FD to date, with 24 months of follow-up. CONCLUSIONS: After the acute phase, radical excision with reconstruction or debulking surgery after skeletal maturation may prevent recurrence. Although malignant transformation is rare, long-term follow-up is necessary for FD.

Nasopharyngeal cancer (NPC) with mastoid recurrence is extraordinarily rare, and its development is thought to involve the Eustachian tube. We herein report a case of NPC with mastoid recurrence masquerading as acute otomastoiditis with facial paralysis in a 60-year-old man 44 months after concurrent chemoradiotherapy. The diagnosis was confirmed by exploratory tympanomastoidectomy with biopsy and Epstein-Barr-encoding region (EBER) in situ hybridization. Distant liver metastasis was detected simultaneously, and the patient underwent salvage treatment. He died 15 months later. Despite the rarity of mastoid recurrence, clinicians should be vigilant in the differential diagnosis of mastoiditis in patients with NPC after radiotherapy. Tumor biopsy and EBER in situ hybridization can aid in the accurate diagnosis of this uncommon condition.

This paper presents a multi-well membrane fabricated using polydimethylsiloxane (PDMS) as a part of a microarray biochip that allows dividable incubation chambers to be provided on a single chip. The conditions of the forming temperature, time, and mixing proportion of the materials were investigated to obtain optimal physical absorption with the surface of the chip substrate. To verify the properties of the multi-well chip, immunoassays were performed by the alpha-1-fetoprotein (AFP) antigen sandwich experiment. The results showed that the detection limit reached to the concentration of 10 ng/ml AFP antigen, and that the dynamic range was 30-3000 ng/ml. Attaining excellent physical absorption helps in avoiding cross-contamination or interference between different samples on the same biochip. The merits of dividable multi-well chips include promoting effective use of surface and multiple-sample experiments.
