Instrumentation Considerations for Calcified Thyroid Cartilage during Chondrolaryngoplasty.

OBJECTIVE: Chondrolaryngoplasty, also known as thyroid cartilage reduction, alleviates gender dysphoria by reducing the thyroid cartilage to conform to a patient's gender identity. Reduction of the thyroid cartilage prominence ("Adam's apple") is often performed with a scalpel, but in cases of cartilage calcification, rongeurs or drills are utilized. This study aims to characterize the success rate with scalpel-only excision and relate this to patient age and operative time. METHODS: Billing records were screened for chondrolaryngoplasties performed between 2020 and 2023 by a single surgeon. Patient demographics, operative notes, and operation duration were recorded. Type of instrumentation was categorized as scalpel only, rongeur, or drill. All cases began with attempted scalpel excision of cartilage and were transitioned to rongeur or drill if there was calcification that prevented sharp excision. Descriptive statistics were used to describe patient and surgical factors. RESULTS: 52 individuals underwent chondrolaryngoplasty: 30 cases (57.7%) had soft cartilage requiring only a blade, 22 (42.3%) required use of either drill or rongeur. The average age of these groups was 25.7 (SE 1.8) and 41.3 years (SE 2.2), respectively; this difference was statistically significant (p < 0.0001). Cases requiring a drill or rongeur lasted on average 78.5 min (SE 2.3), whereas those using only a blade were shorter at 66.8 min (SE 2.7); this difference was significant (p = 0.0017). CONCLUSION: Cartilage calcification should be expected in a significant number of chondrolaryngoplasties, and surgeons should be prepared for this scenario. The need for alternative instrumentation is higher in older individuals and may extend procedural time. LEVEL OF EVIDENCE: 4 Laryngoscope, 2024.

The Subglottic Stenosis 6 Questionnaire: A Novel Quality-of-Life Survey Validated to Predict Need for Intervention in Patients With Idiopathic Subglottic Stenosis.

BACKGROUND: Idiopathic subglottic stenosis (iSGS) is a recurrent, chronic disease defined by fibroinflammatory narrowing of the subglottic airway. A key challenge in treatment is monitoring disease progression, which may be debilitating and unpredictable in its timing. RESEARCH QUESTION: Can the Subglottic Stenosis 6 (SGS-6) questionnaire be validated as a novel quality-of-life (QOL) instrument to monitor breathing, disease progression, and disease severity proactively in patients with iSGS? STUDY DESIGN AND METHODS: Panel data from 51 patients with iSGS were collected from January 2012 through June 2022, representing 1,684 patient encounters including routine office visits and treatment encounters. Subjective QOL scores (including the novel SGS-6 and established RAND-36 and EuroQol Five Dimensions [EQ-5D] Visual Analog Scale) and objective pulmonary function test (PFT) results were collected at each visit. Subjective SGS-6 QOL scores were repeated within 1 week of initial reporting. Panel regression analyses were performed to assess the relationship between SGS-6 scores, PFT results, and a patient's need for intervention. Minimal clinically important differences (MCIDs) for SGS-6 and peak expiratory flow percentage (PEF%) were assessed using receiver operating characteristic (ROC) curve analysis and a patient's need for intervention as the external anchor. RESULTS: Each one-point increase in SGS-6 score (of a maximum of 27) was associated with a 3.26% decrease in PEF%, a 1.93-point decrease in RAND-36 Physical Health composite score, a 1.27-point decrease in RAND-36 Mental Health composite score, and a 0.88-point decrease in EQ-5D Visual Analog Scale score. The intracorrelation coefficient for the SGS-6 composite score is 0.838 (95% CI, 0.770-0.888). Compared with patient baselines, SGS-6 scores were 4.66 points greater at the time of intervention with an MCID of 2.25 from a patient's baseline. The area under the ROC curve for SGS-6 and a patient's intervention point was 0.81. INTERPRETATION: iSGS disease severity can be modeled using the SGS-6 questionnaire, offering physicians and patients a potentially new method of tracking disease progression and need for intervention remotely.

Induced Paresis for Awake Laryngoscopy Procedures.

This article describes an anesthetic technique that induces temporary adductor vocal fold paresis and dense sensory loss of the posterior glottis. This method allows for improved precision of treatment and patient tolerance during awake office-based laryngeal surgery. Laryngoscope, 133:1673-1675, 2023.
