BACKGROUND
Generally, hemangiomas do not require surgical intervention; however, cases of large hemangiomas, potentially involving the throat and trachea, necessitate surgical therapy. Here, we present a case of hypopharyngeal hemangioma in an adult that was successfully treated with neodymium-doped yttrium aluminum garnet (Nd-YAG) laser.
CASE SUMMARY
Laryngoscopic examination of a 61-year-old man demonstrated the presence of a large, submucosal vascular lesion that extended into the epiglottis, left arytenoid cartilage, lateral to the aryepiglottic fold, and pyriform sinus. The lesion was resected and photocoagulated with limited hemorrhage using Nd: YAG laser. The hypopharyngeal hemangioma was completely excised. The patient showed no recurrence of hypopharyngeal hemangioma during the 1.5-year follow-up period.
CONCLUSION
Laser therapy is one of the effective tools for treating hemangiomas with rapid, uncontrolled growth or in functional areas, with few side effects and complications. The present case of a male patient with a large hypopharyngeal hemangioma, treated with YAG laser, demonstrates the efficacy of laser photocoagulation in treating cases of hemangiomas, without the risk of bleeding or airway obstruction. The favorable postoperative outcomes demonstrated by our patient with Nd: YAG laser therapy indicate its consideration in the therapy of similar cases.

Tuberculosis continues to remain a major public health challenge, especially in low- and middle-income countries. Unilateral vocal cord palsy in adults as the sole manifestation of tubercular mediastinal lymphadenopathy has been rarely reported. A 22-year-old lady presented with a history of hoarseness of voice for the past month. The general physical examination revealed palpable lymph nodes in the left axilla. Axial CT sections at the level of the vocal cords demonstrated dilation of the right laryngeal ventricle and mild anteromedial deviation of the ipsilateral arytenoid cartilage ("sail" sign) suggestive of a right vocal cord palsy. Contrast-enhanced CT chest revealed right paratracheal, right hilar, and subcarinal lymph nodes with areas of central necrosis. She was started on anti-tubercular therapy and her voice completely improved after three months of treatment. The "Sail" sign on axial CT scans is a useful radiological sign for diagnosing unilateral vocal cord palsy. Rarely, compression of the recurrent laryngeal nerve by enlarged mediastinal lymph nodes due to tuberculosis can present with unilateral vocal cord palsy as the sole manifestation in adults.

American Journal of Veterinary Research Apr 2024Evaluate a prototype dynamic laryngoplasty system (DLPS) in horses; a feasibility study.
OBJECTIVE
Evaluate a prototype dynamic laryngoplasty system (DLPS) in horses; a feasibility study.
ANIMALS
7 healthy Standardbred adult horses.
METHODS
This was an in vivo experimental study. Horses had a standing surgical procedure to induce complete laryngeal hemiplegia, which was subsequently treated using the dynamic laryngoplasty system (DLPS). Activation of the DLPS was achieved using an injection port exiting through the skin (n = 2) or a subcutaneous injection port (n = 5). For each horse, endoscopic examinations of the upper respiratory tract were performed preoperatively, intraoperatively, and 7 days postoperatively. Left-to-right quotient ratios calculated during inactivated and activated states were obtained from still images of the rima glottidis acquired during day 7. In 3 horses, the device was intentionally overinflated to evaluate for device failure, and postmortem examinations were performed on day 7. For the remaining 4 horses, upper respiratory tract endoscopy was repeated at 1 month postoperatively, with no subsequent postmortem exam.
RESULTS
No perioperative complications occurred, and the DLPS was effectively delivered in all horses under standing sedation. The left-to-right quotient ratio at day 7 postoperatively could be altered from a resting position of 0.76 (± 0.06) to a maximum of 0.97 (± 0.06; P < .05). The degree of arytenoid abduction could not be significantly altered after 1 month of device implantation, suspected to be due to peri-implant fibrosis. No coughing nor tracheal contamination was observed at all time points or during inflation.
CLINICAL RELEVANCE
The ability to alter the degree of abduction at 7 days postoperatively with the DLPS may be beneficial in selective cases.
