Chronic Pharyngitis

Chronic 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,...

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway interventions are...

Suctioning the Nasopharyngeal Airway

Suctioning the Nasopharyngeal Airway

Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.
Equipment Required

Suctioning the Oropharyngeal Airway

Suctioning 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...

Pharynx

Pharynx

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...

Cardiopulmonary Resuscitation II: ACLS Airway Management

Cardiopulmonary Resuscitation II: ACLS Airway Management

Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned under...

Summary

Obstructive sleep apnea (OSA) involves upper airway obstruction. This review details hypopharyngeal surgery as an alternative treatment for patients unable to tolerate CPAP therapy.

Area of Science:

Otolaryngology
Sleep Medicine
Surgical Anatomy

Background:

Obstructive sleep apnea (OSA) stems from upper airway obstruction during sleep.
Hypopharyngeal obstruction can result from tongue base prominence, pharyngeal wall laxity, or epiglottic/aryepiglottic fold issues.
While nasal continuous positive airway pressure (CPAP) is the primary treatment, surgery offers an alternative for CPAP-intolerant individuals.

Purpose of the Study:

To present the current status of hypopharyngeal surgery for treating obstructive sleep apnea.
To outline the diagnostic and planning strategies for hypopharyngeal surgical interventions.

Main Methods:

Review of current literature and surgical techniques for hypopharyngeal obstruction in OSA.
Discussion of preoperative evaluation methods including fiberoptic nasopharyngoscopy and lateral cephalometric radiography.

Emphasis on formulating a tailored surgical plan based on individual airway anatomy.

Main Results:

Hypopharyngeal surgery is a viable option for select OSA patients.
Comprehensive preoperative assessment is crucial for successful surgical outcomes.
Surgical planning involves selecting procedures to specifically target hypopharyngeal collapse.

Conclusions:

Hypopharyngeal surgery represents an important therapeutic avenue for obstructive sleep apnea.
Effective management requires precise anatomical evaluation and individualized surgical approaches.
Further research can refine surgical techniques and patient selection for improved treatment efficacy.
