Insights

Wideband tympanometry (WBT) accurately assesses middle ear status in children with cleft palate, preventing unnecessary surgeries for otitis media with effusion (OME). Post-surgery WBT monitoring is crucial for evaluating hearing function.

Area of Science:

  • Pediatric Otolaryngology
  • Audiology
  • Craniofacial Surgery

Background:

  • Children with cleft palate often undergo unnecessary tympanostomy due to inaccurate otitis media with effusion (OME) evaluations.
  • Wideband tympanometry (WBT) shows promise in improving the accuracy of middle ear assessments in this population.

Purpose of the Study:

  • To investigate the utility of WBT and auditory brainstem response (ABR) indices in children with cleft palate before and after surgical repair.
  • To evaluate the effectiveness of WBT in assessing middle ear status and guiding OME management.

Main Methods:

  • 88 children with cleft palate had WBT and ABR energy absorbance indices measured pre-surgery (3 months prior) and post-surgery (1, 3, and 6 months).
  • Analysis focused on changes in energy absorbance indices and hearing thresholds at different frequencies.

Main Results:

  • Pre-surgery, low-frequency energy absorbance was universally below normal, while high-frequency indices varied.
  • Post-surgery, significant improvements in low-frequency energy absorbance and hearing thresholds were observed (p=0.001).

Conclusions:

  • WBT monitoring effectively aids in surgical decision-making for OME in children with cleft palate.
  • WBT is vital for accurate assessment of middle ear function following cleft palate repair surgery.

Assessing Body Temperature - Tympanic membrane

Assessing tympanic membrane temperature involves using a tympanic membrane thermometer (TMT). Here is a step-by-step guide:
Step 1: Begin by practicing good hand hygiene to prevent the transmission of microorganisms.
Step 2: Turn on the thermometer and wait until the ready sign appears on the screen to ensure accurate measurement.
Step 3: Slide the probe cover in place to prevent cross-contamination.
Step 4: Instruct the patient to tilt their head to the side for comfort and check for cerumen...

Assessing Body Temperature - Oral

Here are the steps to accurately measure oral temperature using an electronic thermometer:
Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.
Step 4:
Instruct the patient to open their mouth and place...
Physical Assessment of the Respiratory Tract III: Percussion01:29

Physical Assessment of the Respiratory Tract III: Percussion

The respiratory system, fundamental to life, consists of complex structures responsible for gas exchange. The percussion assessment is critical to understanding this system's health and functionality. This non-invasive assessment technique allows healthcare providers to evaluate the density or aeration of the lungs, thereby identifying potential abnormalities.

Tracheostomy: Procedure and Tubes01:28

Tracheostomy: Procedure and Tubes

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...
