Acoustical and perceptual vocal profile of beatboxers p. 47
Himanshu Verma, Divya Rana, Amulya Kumari, Nitin Dogra
Background: Beatboxers are elite vocal performers who modify their voice to mimic drum and other instrumental sounds. It requires a lot of modification and manipulation at the level of vocal folds in terms of laryngeal muscles and/or cartilages which may have adverse effect on their vocal profile. As per current literature, there is not much research on the vocal profile of beatboxers. Aim: This study aims to explore the acoustical and perceptual characteristics of beatboxers. Methodology: Ten beatboxers participated in the study. Acoustical and perceptual analyses were done using Praat and Buffalo III voice profile. VRQOL was also performed to assess the voice-related quality of life. Results: The results of the present study revealed significant difference in jitter, shimmer, and harmonic-to-noise ratio values. Rigorous and prolonged practices of beatboxing adversely affect voice. Conclusion: Beatboxing is a vocal phenomenon and may have an adverse effect on vocal musculature due to overloading and manipulation of vocal fold to produce different sounds. This is a preliminary study and further it can be done at larger level with bigger sample size.

Associated airway anomalies and their impact in patients with laryngomalacia: A retrospective review p. 51
Sachin Gandhi, Subash Bhatta, Dushyanth Ganesuni, Asheesh Dora Ghanpur
Introduction: Laryngomalacia is the most common cause of stridor in newborn constituting 50%–75% of all airway anomalies. It is graded as mild, moderate, and severe on the basis of presenting features. It has been shown that 12%–64% of laryngomalacia present with other associated airway anomalies. Here, we have tried to find out the incidence of associated anomalies with laryngomalacia and their impact on the patient's management and prognosis. Materials and Methods: We reviewed patients with laryngomalacia visiting laryngology clinic from January 2014 to January 2019. The incidence and type of associated anomalies; their impact on management protocol and hospital stay; and their association with mild, moderate, and severe grades of laryngomalacia were evaluated. Results: A total of 63 patients were included in the study. Most of the patients presented with severe laryngomalacia (34/63 [53.9%]). Out of them, associated anomalies were present in 23/63 (36%) patients, more common in severe laryngomalacia (16/34 [47.05%]). Tracheomalacia was the most common anomaly (9/63 [14.28%]). The management protocol was changed on the basis of the associated anomalies. The six out of nine patients with tracheomalacia underwent tracheostomy and watchful waiting was done for the other three. The bilateral vocal cords palsy patients underwent partial arytenoidectomy, direct laryngoscopic dilatation was done for all cases of subglottic stenosis, the vallecular cyst patient underwent excision of the cyst and for the patient with laryngeal cleft repairing of the cleft was done after freshening the margins of the cleft. Patients with associated anomalies had statistically significant increased duration of hospital stay (11.35 days) as compared to patients without these anomalies (7.5 days). Conclusion: It can be concluded that associated anomalies are present in a significant number of patients with laryngomalacia and can result in the modification of management protocol and increase in the duration of hospital stay.

Supraglottic stenosis: A rare presentation of granulomatosis with polyangiitis p. 57
Sachin Sharad Gandhi, KC Arun, Deepa Puntambekar
Granulomatosis with polyangiitis is a small-vessel vasculitis involving the airway, lungs, and kidney. Although subglottic involvement is common in the disease, we present a rare case of supraglottic involvement. The patient presented to us with a complaint of change in the voice for 3 months. Endoscopy showed concentric narrowing of supraglottis. Biopsy revealed small-artery vasculitis. c-ANCA was positive. The Patient responded well to medical therapy.

Laryngeal lipoma: A review p. 60
Rakesh Srivastava, Devendra Bahadur Singh, Sunil Kumar
Lipoma is a benign mesenchymal tumor. There are about 115 cases of laryngeal lipoma reported in literature, mostly in isolation. This case was a 52-year-old male who presented with hoarseness of voice and feeling of a lump in the throat for the past 18 months. Examination revealed a solitary huge mass over the left aryepiglottic fold. The tumor was excised using cold instruments with the help of endoscopic technique. There was no recurrence after 24 months of follow-up. With reference to this case, we have a review of literature and a brief discussion on various isolated cases of laryngeal and diffuse lipoma.

Nonrecurrent laryngeal nerve: A rare clinical presentation in thyroid surgery- A report of 2 cases p. 63
Darshan Virendrakuma Doshi, Bhavya N Shah
Surgical damage to the inferior laryngeal nerve is one of the most feared complications of thyroid surgery. A detailed knowledge of anatomical variations is necessary. Nonrecurrent inferior laryngeal nerve is a rare anomaly on the right side and is exceptional on the left. The typical course of the inferior laryngeal nerve is due to the embryological development of the aortic arch and supra-aortic vessels, and nonrecurrence is associated with a vascular anomaly such as a right retroesophageal subclavian artery. The nervous anomaly on the left side is possible only with the occurrence of cardiac dextroposition (situs inversus) and a left retroesophageal subclavian artery. The situation is more dangerous when a nonrecurrent branch of the inferior laryngeal nerve is associated with a recurrent branch. This anomaly does not appear to be associated with a vascular anomaly in all cases. We came across two cases of NRLN after performing 965 thyroid surgeries.

Chondroma of the trachea: A rare benign tracheal tumor p. 66
Darshan Virendrakumar Doshi, Bhavya Nalinbhai Shah
Chondroma of the trachea is a rare neoplasm. Primary tracheal neoplasms are most frequently found in the lower one-third of the trachea. The vast majority of tracheal tumors in adults are malignant. More commonly, the trachea may be involved secondarily by direct extension of tumors of the thyroid, esophagus, larynx, or bronchus. Several authors have reported on the potential of chondromas to undergo sarcomatous change and convert into malignant chondrosarcoma. Because of its recognized potential for local recurrence, a localized chondroma of the trachea is best managed by tracheal resection. We present a case of a 65-year-old male presenting with tracheal chondroma which was diagnosed preoperatively using fine-needle aspiration cytology and computed tomography scan and treated by tracheal resection and anastomosis.
