Tracheostomy: Procedure and Tubes01:28

Tracheostomy: Procedure and Tubes

1.9K
A tracheostomy is a surgical procedure that creates an artificial opening into the trachea, typically at the second or third cartilaginous ring level. This opening allows the insertion of a tracheostomy tube, which can replace an endotracheal tube, provide mechanical ventilation, bypass an upper airway obstruction, or remove accumulated tracheobronchial secretions.
Tracheostomy tubes can be made of semiflexible plastic (polyurethane or silicone), rigid plastic, or metal, and they come in...

Esophageal Strictures-I: Introduction

389
Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...

Enteral Nutrition I: Orogastric and Nasogastric Feeding

736
Enteral nutrition delivers nutrients directly to the stomach or small intestine through a tube. This method is appropriate for patients who cannot eat but still have a functioning digestive system. It is also beneficial for individuals with swallowing difficulties, anorexia, malabsorption, or those who have undergone gastrointestinal (GI) surgery.
Orogastric (OG) and nasogastric (NG) feeding are two standard methods used for enteral nutrition. Enteral nutrition is often preferred over...

Pharynx01:20

Pharynx

4.3K
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...

Oral Cavity01:11

Oral Cavity

2.3K
The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

Summary

Subannular tube (SAT) placement effectively treats chronic middle ear disease in children with cleft palate, improving hearing and ear aeration long-term. This safe alternative requires careful postoperative monitoring for optimal outcomes.

Area of Science:

  • Otolaryngology
  • Pediatric Surgery
  • Medical Devices

Background:

  • Chronic middle ear disease is common in children with cleft palate.
  • Intractable otitis media with effusion and tympanic membrane retraction pose treatment challenges.

Purpose of the Study:

  • To investigate subannular tube (SAT) placement as an alternative treatment for chronic middle ear disease in children with cleft palate.
  • To evaluate audiological outcomes, tube duration, and complications associated with SAT insertion.

Main Methods:

  • Retrospective cohort study involving 21 children with cleft palate (aged 3-14 years).
  • Evaluation of 38 ears treated with transtympanic tubes followed by SAT insertion.
  • Analysis of audiological outcomes, average tube duration, and postoperative complications over a median follow-up of 42 months.

Main Results:

  • SATs remained in situ in 76.3% of cases, with 68.4% of tympanic membranes showing no significant alterations.
  • Mean SAT duration was 16 months, significantly longer than transtympanic tubes.
  • Significant sustained hearing improvement was observed, with a low complication rate (69.2% no complications).

Conclusions:

  • Subannular tube insertion offers a safe and effective long-term solution for middle ear aeration in children with cleft palate.
  • SATs lead to hearing improvement and reversion of tympanic retraction pockets.
  • Close postoperative follow-up is essential for successful treatment outcomes.
