Objectives
To present three case reports of cryptococcal laryngitis managed with potassium-titanyl-phosphate (KTP) laser, where only one case managed with KTP laser has previously been published to date to our knowledge. Further, to systematically review the medical literature and describe the epidemiology, clinical assessment, treatment, and prognosis of laryngeal cryptococcosis.
Methods
The PubMed, Embase, and OVID MEDLINE databases were searched using the terms “cryptococcal laryngitis” or “cryptococcus” and “larynx or laryngeal.”
Results
Thirty-eight cases were identified. The median age was 65 years with a 1 male:1.2 female ratio. Thirty-six cases (95%) presented with hoarseness. Twenty-one cases (55%) were systemically immunosuppressed and 19 (50%) were taking an inhaled corticosteroid. This paper lists the five clinical features (i. white exudate or lesion; ii. exophytic, verrucous or tumor-like mass; iii. diffuse erythema; iv. mucosal irregularity; v. thickened vocal fold) and four pathologic features or tests (i. Grocott Gomori Methenamine stain; ii. Mucicarmine stain; iii. fungal or yeast organisms; iv. fungal culture) that encompass 97% of cases of cryptococcal laryngitis reported in the medical literature. In 34 cases (89%), antifungal therapy was given. Four cases (11%) had excisional biopsy and 11 (29%) received combined surgery and medical therapy. There was uncomplicated resolution in 24 cases (63%).
Conclusion
Cryptococcal laryngitis is a rare cause of hoarseness that may be mistaken for malignancy or may be a manifestation of disseminated cryptococcal infection or underlying immunosuppression. Clinicians should be aware of the diagnostic features of cryptococcal laryngitis to facilitate diagnosis and treatment to prevent complicated disease and overly aggressive treatment.

Objectives
Inflammatory reaction to vocal fold injection laryngoplasty with hyaluronic acid (HA) is a rare condition whose optimal management is not established. In this study, we aim to review the presentation of these reactions and outline an approach for evaluation and management.
Methods
We performed a retrospective review of all patients at our institution who underwent vocal fold injection augmentation with HA during the period extending from August 2018 until October 2022. We then identified patients with postinjection inflammatory reaction and reviewed demographic data, indication for injection, amount of HA injected, setting of procedure, and symptoms. The types of complication, management plan, onset, and time to complete resolution were also recorded. A comprehensive literature search for similar complications was conducted for comparative analysis. Once the available data were aggregated with our institutional experience, we developed an algorithmic approach to manage this condition.
Results
We identified 83 patients (124 vocal folds) who underwent vocal fold injection laryngoplasty with HA over a 4-year period. Four patients (4.8%) had a postprocedure inflammatory reaction (5.6% of all vocal folds). Of the four patients, three presented with dyspnea and stridor, while one presented with dysphonia, with onset of symptoms ranging from 24 to 48 hour postinjection. All patients were treated with corticosteroids. For comparative analysis, we identified 24 patients from the literature with reported inflammatory reactions to HA.
Conclusion
We suggest an algorithmic approach to managing laryngeal inflammation following HA injection. Familiarity with treatment for this rare complication is essential to avoid significant morbidity and achieve optimal outcomes.

Objectives
There is currently no research reporting solely on outcomes of voice and communication modification training (VCMT) in individuals who identify as non-binary and genderqueer (NBGQ) in the English literature. This study aimed to describe the objective and subjective impact of VCMT on the voice of NBGQ individuals undergoing a 12-week gender-affirming VCMT program.
Methods
A retrospective consecutive case series of NBGQ individuals enrolled in a VCMT program was performed. Demographics, Transgender Self-Evaluation Questionnaire (TSEQ), fundamental frequency (F0), and frequency range were collected before and after the program.
Results
Four NBGQ individuals enrolled between January 2019 and June 2021; the mean age was 27.0 years. While all four participants represented in this case series showed improvement in at least one of their initial goals, only one improved both their F0 and TSEQ scores; the other three participants had mixed results.
Conclusion
NBGQ individuals experienced improvements in self-reported outcomes and changes in acoustic measures after completing VCMT in our case series. Individuals experienced significant improvement in subjective outcomes despite small changes in acoustic measures, and vice versa. More research is needed to better understand the voice and communication needs of NBGQ individuals, along with their outcomes with VCMT.

Resonance properties of the nasal and sinus cavities are involved in the individuality of speech. However, detailed information on how alterations in the nasal cavity morphology affect voice quality is lacking. The aim of the present study was to investigate the effects of structural changes in the nasal cavity on voice production by spraying a topical adrenaline solution with a vasoconstrictive effect into the nasal cavity, causing nasal mucosal contraction.
Study Design
Prospective.
Methods
Overall, 51 adult volunteers were recruited from the Otorhinolaryngology Outpatient Department of the Jikei University Hospital from June to September 2022. Among them, 20 completed acoustic rhinometry and voice recordings before and after adrenaline spraying. The nasal consonant [N] uttered with the mouth completely closed was recorded for 5 seconds. The remaining 31 volunteers completed all auditory experiments. This was conducted to determine whether the changes in voice before and after adrenaline spraying could be discriminated against by the participants.
Results
The nasal volume had increased 5 and 10 minutes after spraying compared to that before spraying, reaching a significance at 10 minutes (P = 0.06). It had increased at 2 and 5 cm from the external nostrils compared to that within 3 cm of the external nostrils (P = 0.04). Among the 31 volunteers in the auditory experiments, 30 had a discrimination rate >90%, with a mean of 96.3% (standard error, 3.2). The spectral envelope of the 16 frequency bands varied significantly at 500-Hz increments (P = 0.0006). In particular, changes in the high-frequency bands were larger between 4500 and 6000 Hz.
Conclusions
Nasal enlargement with 0.02% topical adrenaline affects the spectral envelope, particularly in the high-frequency bands between 4500 and 6000 Hz, and perceptibly alters the voice.

Background
As the world becomes increasingly interconnected, the demand for bilingual teachers has grown exponentially. However, the unique combination of being a bilingual occupational voice user establishes challenges that warrant careful examination.
Objective
To investigate the association between bilingualism, vocal effort, and background noise with fundamental frequency and long-term spectrum average among Spanish-English bilingual teachers.
Methods
Exploratory cross-sectional correlational study with the participation of eight Spanish-English proficient bilingual teachers (native Spanish speakers) who were teaching online classes during the quarantines established to mitigate the propagation of COVID-19. Participants were asked to read two standardized texts (one in English and one in Spanish) under two background noise conditions (with and without background white noise).
Results
There was a significant interaction between language and vocal effort considering that the association of vocal effort with fo was different for Spanish and English. There was also a significant main effect of background noise on fo. There were significant differences in voice spectral characteristics between productions in Spanish and English and between productions with and without background noise. The alpha ratio was significantly higher in productions in English and with background noise compared with productions in Spanish without background noise. The mid to high spectral energy ratio (1–5 K/5–8 K) was significantly lower in productions in English and with higher perceived vocal effort compared with productions in Spanish and with lower scores on the Borg Scale.
Conclusion
Our findings introduce a need perspective by emphasizing the impact of speaking a second language on the work-relatedness of voice disorders among teachers. These findings stress the necessity to factor in language and environmental conditions for the comprehensive evaluation and management of work-related voice disorders.

Objective
The vibratory source for voicing in children with dysphonia is classified into three categories including a glottal vibratory source (GVS) observed in those with vocal lesions or hyperfunction; supraglottal vibratory sources (SGVS) observed secondary to laryngeal airway injuries, malformations, or reconstruction surgeries; and a combination of both glottal and supraglottal vibratory sources called mixed vibratory source (MVS). This study evaluated the effects of vibratory source on three primary dimensions of voice quality (breathiness, roughness, and strain) in children with GVS, SGVS, and MVS using single-variable matching tasks and computational measures obtained from bio-inspired auditory models.
Methods
A total of 44 dysphonic voice samples from children aged 4–11 years were selected. Seven listeners rated breathiness, roughness, and strain of 1000-ms /ɑ/ samples using single-variable matching tasks. Computational estimates of pitch strength, amplitude modulation filterbank output, and sharpness were obtained through custom-designed MATLAB algorithms.
Results
Perceived roughness and strain were significantly higher in children with SGVS and MVS compared to children with GVS. Among the computational measures, only the modulation filterbank output resulted in significant differences among vibratory sources; a posthoc test revealed that children with SGVS had greater amplitude modulation than children with GVS, as expected from their rougher voice quality.
Conclusions
The results indicate that the output of an auditory amplitude modulation filterbank model may capture characteristics of SGVS that are strongly related to the rough voice quality.

Objectives
We evaluated the preventive efficacy of stromal vascular fraction (SVF) for vocal fold scar in a rabbit model.
Study design
Animal model.
Methods
The study included 40 male New Zealand white rabbits: 20 received vocal fold scar surgery served as normal controls (control group). The other 20 received the same vocal fold scar surgery with SVF injection (SVF group)
Histological and high-speed video analyses of vocal fold vibration were performed 4 weeks after scar surgery and SVF injection. The maximum amplitude of vocal fold vibration was used to assess vocal fold vibration. A real-time PCR study was also performed to evaluate the scar regeneration and remodeling including TGF-ß1, IL-6, procollagen-1, MMP-2, 9, and HAS-2, 3.
Results
Vocal fold vibration analyses indicated that the maximum amplitude differences in the vibration of the SVF group were significantly higher than the control group. The histological findings showed that the collagen density ratio were significantly lower in the SVF group compared to the control group. Real-time Polymerase Chain Reaction (PCR) study showed significant increases of MMP-2, 9 and HAS-2, 3, and a decrease of TGF-ß1, IL-6, procollagen-1 in the SVF group compared to the control group.
Conclusions
Based on the vocal fold vibration study, histological findings, and real-time PCR study, SVF injection showed preventive activity and improvement of vocal fold vibration for vocal fold scar in a rabbit model.
