Summary
Reconstructing pharyngeal defects is challenging. This review covers current surgical techniques, including traditional flaps and modern microvascular options, to restore function after head and neck surgery.
Area of Science:
- Head and Neck Surgery
- Reconstructive Surgery
- Oncology
Context:
- Pharyngeal defects pose significant challenges for head and neck surgeons.
- Reconstructive surgery aims to balance oncologic outcomes with patient quality of life.
- Preserving speech, airway, and swallowing functions is paramount.
Purpose:
- To review current reconstructive techniques for pharyngeal defects.
- To compare classical and contemporary surgical options.
- To highlight advancements in head and neck reconstruction.
Summary:
- Classical methods include pedicled cervical and distal myocutaneous flaps (e.g., pectoralis major).
- Current microvascular techniques offer high success rates with varying complication profiles.
- The article provides an overview of the most up-to-date reconstructive strategies.
Impact:
- Informs surgical decision-making for pharyngeal defect reconstruction.
- Aids in optimizing functional outcomes and patient well-being.
- Contributes to the understanding of head and neck surgical advancements.

01:20Pharynx
The pharynx, a tubular structure framed by skeletal muscle and lined with mucous membrane, extends continuously from the nasal cavities. It is segmented into three major areas: the nasopharynx, oropharynx, and laryngopharynx.
Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...

01:29Anatomy of Respiratory System I: Upper Respiratory Tract
The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.
Nose and nasal cavity
The nose and nasal cavity represent the main external openings of the respiratory tract.

01:25Suctioning the Oropharyngeal Airway
In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

01:23Chronic Pharyngitis
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

01:21Tracheostomy Decannulation
Tracheostomy decannulation is a significant milestone in the liberation of mechanically ventilated patients. Despite its importance, there is no universally accepted protocol for this procedure. This demands an evidence-based, individualized approach.
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...
