Severe or Profound Sensorineural Hearing Loss Caused by Novel USH2A Variants in Korea: Potential Genotype-Phenotype Correlation
Sang-Yeon Lee, Kwangsic Joo, Jayoung Oh, Jin Hee Han, Hye-Rim Park, Seungmin Lee, Doo-Yi Oh, Se Joon Woo, Byung Yoon Choi
Clin Exp Otorhinolaryngol. 2020;13(2):113-122.

• We report two novel USH2A variants from two probands manifesting more than severe sensorineural hearing loss (SNHL) and retinal problems.
• USH2A should also be included in the candidate gene list of cochlear implantees.
• A specific combination of USH2A alleles may contribute to the differential expressivity of SNHL, suggesting a possible genotype-phenotype correlation.
• The understanding of audiological complexity associated with USH2A will impact clinical practice in a way that would change genetic counseling and treatment strategy.

Vestibulocochlear Symptoms Caused by Vertebrobasilar Dolichoectasia
Gene Huh, Yun Jung Bae, Hyun Jun Woo, Jung Hyun Park, Ja-Won Koo, Jae-Jin Song
Clin Exp Otorhinolaryngol. 2020;13(2):123-132.

• Vestibulocochlear symptoms can be precipitated by eighth cranial nerve compression by vertebrobasilar dolichoectasia (VBD).
• Appropriate management may improve symptoms in subjects with VBD.
• Radiological evaluation is needed when vestibulocochlear symptoms are not explicable.
• A thorough neurotological evaluation is recommended prior to treatment of VBD.

Changes in Cortical Auditory Evoked Potentials by Ipsilateral, Contralateral and Binaural Speech Stimulation in Normal-Hearing Adults
Jee Yeon Lee, Byung Chul Kang, Jun Woo Park, Hong Ju Park
Clin Exp Otorhinolaryngol. 2020;13(2):133-140.

• Cortical auditory evoked potentials represent response of auditory cortex to a sound stimulation.
• Sounds from different input sides are encoded differently at the cortical level.
• Spectrally different speech sounds are also encoded differently at the cortical level.

Assessment of Objective Audiometry to Predict Subjective Satisfaction in Patients With Hearing Aids
Min Young Kwak, Woo Ri Choi, Jun Woo Park, Eun Jeong Hwang, Yeo Ra Ha, Jong Woo Chung, Woo Seok Kang
Clin Exp Otorhinolaryngol. 2020;13(2):141-147.

• Audiometric outcomes and subjective questionnaire scores showed a statistically significant improvement after hearing aid fitting.
• Subjective satisfaction in hearing aid users is affected not only by acoustic gain improvement but also by other individual factors.
• Objective audiometric tests and subjective questionnaire should be performed together for validating hearing aid performance.

Clinical Characteristics Other Than Intralesional Hyperdensity May Increase the Preoperative Diagnostic Accuracy of Maxillary Sinus Fungal Ball
Hyunkyung Cha, Yoonjae Song, Yun Jung Bae, Tae-Bin Won, Jeong-Whun Kim, Sung-Woo Cho, Chae-Seo Rhee
Clin Exp Otorhinolaryngol. 2020;13(2):157-163.

• The intralesional hyperdensity lesion on the computed tomography (CT) scan is highly specific for maxillary sinus fungal ball; however, a significant proportion of patients may not present with intralesional hyperdensity.
• Age and characteristic non-intralesional hyperdensity lesions, the presence of an irregular protruding lesion and maxillary sinus full haziness with mass effect in the CT scans are associated with the presence of maxillary sinus fungal ball.
• Demographic parameter and characteristic non-calcified lesion increase the overall diagnostic accuracy of maxillary sinus fungal ball.

Tumor Control and Quality of Life in Skin Cancer Patients With Extensive Multilayered Nasal Defects
Michaela Plath, Hannah M. Thielen, Ingo Baumann, Karim Zaoui, Philippe A. Federspil
Clin Exp Otorhinolaryngol. 2020;13(2):164-172.

• Surgery in advanced nasal skin cancer patients results in an excellent prognosis.
• Quality of life is equal in nasal reconstruction and prosthetic rehabilitation for extensive skin cancer defects.
• Nasal reconstruction and prostheses are both very viable options depending on tumor stage and biology, patient’s wishes as well as the experience of the surgeon.

Which Plosive Consonant Is More Useful for the Aerodynamic Analysis of Pathologic Voice?
Yong Tae Hong, Phan Huu Ngoc Minh, Ki Hwan Hong
Clin Exp Otorhinolaryngol. 2020;13(2):179-185.

• The purpose of the study is to present and to discuss the magnitude of the correlations between acoustic measures and aerodynamic measures according to the types of plosive consonants.
• The correlation between acoustic and aerodynamic parameters was significantly larger with the plosive consonant /phi/ compared with the stop consonants /p’/ and /p/. The magnitudes of correlation were higher with the plosive consonant /phi/ compared with the consonants /p’/ and /p/.
• The consonant /phi/ may represent a more valuable investigative consonant than the consonants /p/ or /p’/ for aerodynamic analysis of voice pathology, especially in the unilateral vocal fold paralysis.
