Objectives: It has been proven that patients with unilateral conductive hearing loss (UCHL) may encounter typical problems associated with asymmetric hearing, especially in challenging listening environments. In this study, we aimed to determine how UCHL affects speech recognition under multisource competing environments and the ability of sound source localization, as well as whether assistance with a bone conduction device (BCD) can confer hearing benefits in such listening tasks. Design: Acquired UCHL was simulated using an earplug combined with an earmuff in 10 listeners (mean age: 29.9 ± 4.77 years) with bilateral normal hearing (NH), and a within-subject repeated-measures design was used to compare hearing results among three listening conditions: NH (both ears open, C1), unilateral plug (UP) (simulated UCHL, C2), and UP + BCD (simulated UCHL aided with a BCD, C3). The speech reception threshold (SRT) of summation, squelch, and head shadow (HS) effects and the mean absolute error of sound source localization were used as markers for binaural hearing abilities. Results: BCD assistance (C3) improved the summation and HS effects in all listeners with simulated UCHL, resulting in a lower (i.e., better) SRT than that observed in C2; however, no significant differences in squelch effects were observed between C2 and C3. Notably, most listeners exhibited more accurate sound source localization in C3 than in C2. Further, BCD assistance mainly improved localization accuracy when the noise stimuli were presented at low intensities and on the hearing-impaired (plugged) side, suggesting that the benefits of BCD for sound localization are not based on the reacquisition of binaural processing. Conclusions: The current results have clinical implications for the promotion of BCDs in patients with UCHL, especially those with acquired UCHL who are unable to undergo surgery.

This is a case report on the treatment of tracheal glomus tumor, which is a rare tumor originating from the glomus bodies in the trachea and form spherical or nodular masses. These tumors can lead to obstruction and narrowing of the tracheal lumen, causing symptoms such as dyspnea. The standard treatment for tracheal glomus tumors is typically surgical resection. In this case, the patient underwent a procedure involving low tracheostomy with closure of the airway and mechanical ventilation through the stoma, followed by endoscopic-assisted subglottic tracheal glomus tumor resection using plasma-assisted radiofrequency.

Multiple endocrine neoplasia type 2B (MEN2B) syndrome is a rare genetic disorder primarily driven by mutations in the RET proto-oncogene. MEN2B exhibits diverse symptoms affecting multiple organ systems, with mucosal neuromas being a prominent feature. These benign tumors contribute to the syndrome's clinical variability, alongside medullary thyroid carcinoma and pheochromocytoma. The article presents a case study of a young girl diagnosed with MEN2B, complicated by laryngeal neuromas leading to respiratory distress post-thyroidectomy. Laryngeal neuromas are exceedingly rare, underscoring the importance of recognizing such manifestations for proper airway management, especially during surgical interventions. Despite its rarity, MEN2B presents significant clinical challenges, requiring early detection, genetic counseling, and multidisciplinary management for improved outcomes. Clinicians must remain vigilant for rare manifestations like laryngeal neuromas to prevent serious complications, particularly during surgical procedures.

Cystic lymphangioma is a rare benign congenital malformation of the lymphatic system. It usually presents in childhood and rarely in young adults. Its management lacks consensus, and its prognosis varies depending on the location. We report a case of cervical cystic lymphangioma in a young adult with chronic left lateral cervical swelling. Examination revealed a high jugulocarotid swelling, non-pulsatile, and transilluminable. Radiographic exploration suggested a cystic lymphangioma. Histopathology confirmed the diagnosis. The patient underwent a sclerotherapy session, followed by surgical excision. Our case illustrates a rare presentation of cervical cystic lymphangioma in a young adult and aims to increase awareness of this rare entity and provide literature insights into its diagnosis and treatment in adult patients.

Objective: At our institution, thyroid preservation during total laryngectomy (TL) varies by surgeon, offering a distinctive dataset to compare disease outcomes in TL patients with or without thyroidectomy. Methods: This retrospective chart review study, conducted at a tertiary referral medical center, comprises patients who underwent TL for laryngeal or hypopharyngeal squamous cell carcinoma from 2014 to 2022. The study includes data on patient demographics, surgeries, pathological staging, tumor subsites, thyroid involvement, and adjuvant therapy. Results: In this study, 147 patients, mostly male (83%) and white (82%), were included. Surgeries comprised 60 hemi thyroidectomies, 35 total or completion thyroidectomies, 48 without thyroid removal, and 4 isthmusectomies. Data analysis compared these 4 groups and the cohort of no thyroid removal (NT) versus any thyroidectomy (T = 99). Among the 99 patients, 27 showed positive gland involvement, primarily due to direct disease extension (26 cases). No significant difference was found in recurrence rates or recurrence-related mortality among the 4 groups or between NT and T (P = .156). However, there was a significant difference in T staging and prognostic staging among the groups and between NT versus T (P = .043). The NT cohort showed a higher likelihood of being T3, while T was more likely to be T4. Conclusion: We found no significant difference in recurrence rates or mortality between TL patients with or without thyroid removal. However, those without thyroid removal often had lower T stages. Notably, 27% of thyroidectomy patients had gland invasion, highlighting the importance of thyroid removal in TL.

Objectives: Surgical outcomes determine national ranking, reputation, and funding, and are often assessed with objective surgical risk calculators (SRCs). Surgeons' assessments are not considered. This study aims to determine if surgeons or SRCs are more accurate in predicting outcomes. Methods: This prospective cohort study identified a surgeon's assessment on a patient's risk preoperatively. The patient's risk was also calculated using the SRC. Predictions were compared to patient outcomes and to each other to assess whether surgeons or the SRC were more accurate. Results: Of the 101 patients included, 37 (36.6%) experienced a complication of any kind and 18 (17.8%) experienced a serious complication. Smoking resulted in a 2.49 times higher overall complication rate (P = .04). Laryngectomy patients experienced the highest rate of complications (P = .02) compared to those undergoing free flap reconstruction [odds ratio (OR) 0.9] or any other surgery (OR 0.26). Both surgeons and the American College of Surgeons (ACS) tool performed poorly on the prediction of the outcome of any complication, with a receiver operating characteristic (ROC) area under the curve (AUC) of 0.51 [95% confidence interval (CI): 0.39-0.62] and 0.58 (95% CI: 0.47-0.70), respectively, which was not statistically significant (P = .34). For the prediction of the outcome of serious complication, the AUC for surgeons and the ACS tool were 0.55 (95% CI: 0.41-0.69) and 0.60 (95% CI: 0.46-0.74), respectively, which was not statistically significant (P = .58). Conclusions: Neither validated risk calculators nor surgeons are accurate in predicting perioperative risk. The only risk factor that contributes to improving predictions for complications is preoperative smoking, although age and type of surgery are also significant predictors. Risk calculators may therefore not be appropriate metrics for assessing hospital performance. These findings can help guide preoperative counseling and may help in the development of more accurate predictive tools as the healthcare field continues to incorporate artificial intelligence into surgical planning.
