A Retrospective Study of Glottic Cyst Histopathology and Its Clinical Presentation.

To understand the frequency and clinical presentation of the four types of vocal-fold cyst described by the Koren classification. Glottic cysts operated in a 1-year period were grouped retrospectively into Koren A, B, C and D (KA, KB, KC, KD). The age and sex of the patient, cyst location, laterality, associated lesions, profession, daily water consumption, duration of symptoms prior to surgery and postoperative healing time were noted.

Hemorrhagic Pseudocyst (Polyst) and True Hemorrhagic Cyst of the Vocal Fold.

Objectives: Though hemorrhagic vocal fold polyps are a common entity, hemorrhagic vocal fold cysts have not been previously described. In our study, we have evaluated patients who were diagnosed on stroboscopy with "hemorrhagic" cysts.

Methods: This 18-month retrospective study has received institutional ethics clearance.

Utility of maximum phonation time in the diagnosis of spasmodic dysphonia (laryngeal dystonia).

Objectives: Maximum phonation time is a simple test used to assess glottic competency. Our objective was to evaluate any correlation between maximum phonation time and spasmodic dysphonia as adductor spasmodic dysphonia and abductor spasmodic dysphonia have an adductor and abductor overdrive, respectively.

Methods: A 3-year data-review was performed for patients diagnosed with adductor spasmodic dysphonia, abductor spasmodic dysphonia and mixed spasmodic dysphonia.

Vocal Outcomes Following Pitch Alteration Surgeries.

Our study aims to ascertain the results of speech therapy and surgery in patients who desire pitch alteration. Typically, patients desirous of an increase in their vocal pitch are male-to-female transpersons, and patients desirous of a drop in their pitch are puberphonia patients. This is a 3-year retrospective study of patients who have been operated for pitch alteration.

Vocal Outcomes Following Laser-Assisted Sulcus Release for Superficial and Deep Vocal Fold Sulcus.

Background: The objective is to study vocal outcomes following laser-assisted sulcus release (LASR), having documented the length and depth of the sulcus intraoperatively. LASR performed for superficial and deep sulci were included.

Study Design: Retrospective, observational.

Correlation of narrow-band imaging findings using the Ni and European Laryngeal Society classification systems during in-office flexible laryngoscopy with histopathology.

Objective: This study used the European Laryngeal Society (2016) and Ni (2011 and 2019) classifications for narrow-band imaging and correlated the findings with histopathology.

Methods: Retrospective analysis was conducted by retrieving data of patients who underwent micro-laryngoscopy for suspicious glottic lesions. The narrow-band imaging findings were classified using both classification systems.

Glottic Neurofibroma: An Unusual Case Report.

Solitary neurofibromas of the larynx occur sporadically and usually tend to involve the aryepiglottic folds. Non-plexiform variants of neurofibromas involving the glottis are extremely rare and may have defined margins versus plexiform subtype which are often unencapsulated and associated with Von Recklinghausen's disease. We report an unusual case of isolated glottic neurofibroma in an elderly male with gradually progressive hoarseness of voice with stroboscopy findings of a right unilateral, bulky subepithelial lesion mimicking a vocal fold cyst.

A Four Year Retrospective Study of the Pattern of Fungal Laryngitis in a Tertiary Voice Care Centre.

Isolated Fungal Laryngitis (FL) has recently shown an increased incidence globally and is now being reported even in immunocompetent individuals. In our Voice Clinic we have documented an increasing number of cases of FL, specifically laryngeal candidiasis, with the lesion over the striking zone (anterior 1/3rd posterior-2/3rd) of vocal folds. Our objective was to study the sites of involvement of FL within the glottis along with a review of literature.

A Retrospective Study to Assess the Accuracy of Frozen Sections in Laser Laryngeal Surgery.

Objective: The basis of good vocal outcomes following Transoral Laser Microlaryngeal Cordectomy (TLMC) is the narrow margin that is oncologically accepted for the glottis. Our objective is to evaluate the reliability of frozen section (FS) compared to paraffin section (PS) during TLMC and during laser laryngeal surgery when an incisonal or excisional biopsy is being performed.

Methods: Retrospectively, records of 159 sequential patients who underwent CO laser laryngeal surgery with intraoperative FS were reviewed along with the final PS.

A Prospective Study to Correlate Difficult Intubation with Difficult Laryngeal Exposure for Microlaryngeal Surgery using Various Grading Scales of Difficult Intubation.

Adequate visualization of the vocal folds is essential for optimal phonosurgery. Pre-operative knowledge of a difficult laryngeal exposure (DLE) can alert the surgeon regarding the need for alternative measures. Our study is based on the hypothesis that a patient who has difficult intubation (DI) is likely to have DLE, thus scales anticipating DI should also anticipate DLE.

Sulcus vocalis in spasmodic dysphonia-A retrospective study.

Background: Spasmodic dysphonia (SD) is a neurological condition of the larynx characterised by task specific, involuntary spasms of the intrinsic laryngeal muscles causing frequent voice breaks during speech. The current treatment modality involves Botulinum Toxin injections into the affected group of muscles. This has yielded satisfactory results in Adductor SD (ADSD) and mixed SD but not in Abductor SD (ABSD).

A 4-year Retrospective Review of the Presence and Pattern of Ventricular Hyperadduction Following Unilateral Vocal Fold Paralysis, Paresis, and Unilateral Cordectomy.

Background: The aim of our study was to determine the presence and pattern of ventricular hyperadduction (VH) following unilateral vocal fold (VF) paralysis/paresis and that following unilateral cordectomy (UC).

Methods: The authors independently reviewed charts and flexible videostroboscopic recordings of 214 patients diagnosed with unilateral VF paralysis/paresis and those who had undergone UC from 2015 to 2018. The presence and pattern of VH was noted.

A 10-year study of the etiopathogenesis of cysts with a study of seromucinous glands in vocal folds.

Objective: An increasing number of vocal fold cysts excised, as compared to polyps, over the last decade led us to review these cases. We found a statistically significant increase in cysts excised as compared to polyps, over the latter 5-year period (2013-2017). This prompted us to analyze possible factors responsible for this increase.

Factors responsible for the development of carbon granuloma post transoral laser cordectomy.

Our study was performed with an aim to analyse the factors responsible for the formation of a carbon granuloma (CG) following transoral laser microlaryngeal cordectomy (TLMC) for early glottic carcinoma. Our study comprises of retrospective data analysis of 78 patients who underwent TLMC for early glottic carcinoma between 2012 and 2017 with the laser settings of an acublade with scanning system, size 1-2 mm, depth 1-3 (250-750 μm), power 10 watts in a repeat mode with time off 0.25 s.

Anatomical Course of the Thyroarytenoid Branch of the Recurrent Laryngeal Nerve.

Objectives/hypothesis: To determine the position and anatomic variability of the thyroarytenoid (TA) branch of the recurrent laryngeal nerve (RLN) in an Indian population. This study is specifically targeted to aid in identifying the nerve for reinnervation procedures for unilateral and bilateral vocal fold paralysis, as well as denervation surgeries such as TA myoneurectomy and Selective Laryngeal Adductor Denervation and Reinnervation (SLAD-R) for adductor spasmodic dysphonia.

Methods: We dissected 46 fresh-frozen adult larynges (92 sides) without pathology.
