Epiglottidectomy

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

An epiglottidectomy is a surgical procedure aimed at addressing dysphagia, which is difficulty in swallowing, that arises from dysfunction of the epiglottis. This condition may occur following cancer treatment or as a result of airway narrowing associated with obstructive sleep apnea. The epiglottis is a flap of tissue located at the root of the tongue that plays a crucial role in protecting the larynx during swallowing by covering it to prevent food and liquids from entering the airway. The epiglottis is made up of elastic fibrocartilage and is covered by a mucous membrane, which contributes to its flexibility and function. During an epiglottidectomy, a portion or the entirety of the epiglottis is excised to alleviate the symptoms associated with its dysfunction. The procedure can be performed using different approaches, including an open incisional method or a trans-oral approach, depending on the specific clinical scenario and the extent of the epiglottic involvement. The surgical technique involves careful dissection and removal of the epiglottis while ensuring that surrounding structures are preserved as much as possible to minimize complications and promote recovery.

1. Indications

The epiglottidectomy procedure is indicated for specific conditions that affect the function of the epiglottis and lead to complications such as dysphagia or airway obstruction. The following are the primary indications for performing an epiglottidectomy:

  • Dysphagia due to epiglottic dysfunction - This condition may arise following cancer treatment, where the epiglottis may not function properly, leading to swallowing difficulties.
  • Airway narrowing in obstructive sleep apnea - The procedure may be indicated to alleviate airway obstruction caused by epiglottic issues, which can contribute to obstructive sleep apnea symptoms.

2. Procedure

The epiglottidectomy procedure can be performed using different surgical approaches, each with specific steps involved. The following outlines the procedural steps for both the open incisional approach and the trans-oral approach:

  • Open Incisional Approach - The procedure begins with the creation of a horizontal skin incision in the neck at the level of the hyoid bone. The surgeon dissects through the subcutaneous tissue to reach the platysma muscle, which is then incised to expose the hyoid bone. The hyoid muscles are released to allow access to the pharynx. An incision is made in the pharynx just above the hyoid, allowing entry into the vallecular space. The epiglottis is then exposed and inspected. If a lesion is present, the mucosa may be excised, and the perichondrium is stripped from the underlying fibrocartilage of the epiglottis. After the epiglottis is removed, the pharynx is closed in layers, followed by closure of the overlying muscle, soft tissue, and skin. A drain is placed in the subplatysmal space to facilitate fluid drainage.
  • Trans-Oral Approach - In this method, a laryngoscope, such as a Dedo or Lindholm scope, is inserted through the mouth to provide visibility of the epiglottis. A microscope attachment with a carbon dioxide laser is then introduced to resect up to half of the epiglottis, typically at a location midway between the tip of the epiglottis and the hypoepiglottic ligament. Alternatively, monopolar diathermy may be utilized for the excision. During this approach, care is taken to ablate the demucosalized epiglottic cartilage to minimize the risk of infection or necrosis.

3. Post-Procedure

After the epiglottidectomy, patients may require specific post-operative care to ensure proper recovery. This may include monitoring for any signs of complications such as infection or bleeding. Patients are typically advised on dietary modifications to accommodate their swallowing capabilities during the recovery period. Follow-up appointments are essential to assess healing and to determine if further interventions are necessary. Additionally, the placement of a drain in the subplatysmal space may require care to prevent fluid accumulation and promote healing.

22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
GC This service has been performed in part by a resident under the direction of a teaching physician
