Larynx

6.2K
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

Summary

Laryngeal sarcoidosis (LS) is rare and challenging to manage, often presenting with other symptoms. While survival is good, treatment requires a medico-surgical approach and long-term care.

Area of Science:

  • Pulmonology
  • Otolaryngology
  • Rheumatology

Background:

  • Sarcoidosis is a multisystem inflammatory disease of unknown cause.
  • Laryngeal sarcoidosis (LS) is a rare but potentially severe manifestation.
  • Understanding LS clinical features and prognosis is crucial for patient management.

Purpose of the Study:

  • To characterize laryngeal manifestations of sarcoidosis.
  • To analyze the clinical expression and long-term follow-up of LS patients.
  • To compare LS patients with sarcoidosis patients without laryngeal involvement.

Main Methods:

  • Retrospective case-control study.
  • Inclusion of all LS patients from two French centers.
  • Comparison with sarcoidosis patients without laryngeal involvement and controls.

Main Results:

  • Twelve LS patients were identified; 67% presented with LS as the initial manifestation.
  • Common symptoms included hoarseness (77%), inspiratory dyspnea (38%), and dysphagia (38%).
  • LS patients showed higher rates of extrapulmonary involvement (92%), particularly lupus pernio and nasosinusal disease, but less thoracic involvement (58%).
  • Treatment was more frequent (92%) and longer (median 81 months) in LS patients, with lower remission rates (9% vs. 58% at 2 years).
  • Two patients required surgery, and one needed temporary tracheostomy; no deaths or permanent tracheotomies occurred.

Conclusions:

  • Laryngeal sarcoidosis is rare and frequently associated with other localized or regional sarcoidosis.
  • LS management is challenging, often necessitating a combined medical and surgical strategy.
  • Despite difficulties in management, survival is favorable, though long-term treatment and monitoring are often required.
