Summary
Hegar
Area of Science:
- Otolaryngology
- Pediatric Surgery
Background:
- Choanal atresia, a congenital condition causing nasal obstruction, presents a significant challenge in neonates.
- Bilateral choanal atresia is a medical emergency requiring prompt surgical intervention.
Purpose of the Study:
- To evaluate the efficacy and safety of using Hegar's dilators for surgical correction of choanal atresia.
- To assess surgical outcomes in patients with choanal atresia, including those with CHARGE Syndrome.
Main Methods:
- A retrospective study of 22 patients who underwent surgery for choanal atresia by the first author.
- Surgical correction involved using Hegar's dilators to address bony or membranous atresia.
- Nasal stenting was employed in all cases post-operatively.
Main Results:
- Hegar's dilators proved to be a safe and simple surgical method for choanal atresia.
- Complete nasal patency was achieved in all surgically treated cases.
- While surgery was successful, 8 neonates with CHARGE Syndrome did not survive due to their underlying condition, unrelated to surgical outcomes.
- 14 cases not associated with CHARGE Syndrome showed good postoperative recovery.
Conclusions:
- Hegar's dilators offer a safe and effective surgical approach for choanal atresia.
- Nasal stenting is crucial for preventing restenosis after surgical correction.
- While surgical outcomes for choanal atresia are generally positive, associated conditions like CHARGE Syndrome significantly impact patient survival.

Breathing

The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...

Vasectomy is a surgical form of male sterilization that involves severing and sealing the vasa deferentia, preventing sperm from mixing with semen during ejaculation. Because a vasectomy does not impact the testes' ability to produce testosterone, hormone levels, libido, and sexual function generally remain unchanged. While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although...

Introduction to Inspiration: The Respiratory System in Action
The respiratory system, an essential network for breathing, comprises the conducting and respiratory zones, each playing a crucial role in the overall process of respiration. Let us explore the detailed mechanism of inspiration, or inhalation, which is the first phase of the respiratory cycle.
Pathway of Air during Inspiration
During inspiration, air enters our body through the nose or mouth and moves through the conducting zone,...

The Physiology of Expiration: A Seamless Respiratory Process
Expiration, or exhaling, is a complex physiological process that begins as the inspiratory muscles begin to relax. This relaxation triggers a series of events that epitomize the efficiency of the respiratory system.

Gastrointestinal (GI) diagnostic studies are pivotal in confirming, ruling out, diagnosing, or staging various diseases, including cancers. Following diagnosis, allocating time for discussions with the patient and providing informational resources is crucial. Diagnostic assessments of the GI tract often occur in outpatient settings like endoscopy suites or GI labs. Preparation for these tests may include dietary restrictions, fasting, liquid bowel preparations, laxatives, enemas, and the...

Mechanism of Breathing III: The Accessory Muscles

The Role of Accessory Muscles in the Respiratory System
The respiratory system is a complex network that relies on primary respiratory muscles like the diaphragm, but also involves accessory muscles to enhance lung expansion and airflow during both inhalation and exhalation.
Enhancing Inhalation with Accessory Muscles:
Accessory muscles such as the sternocleidomastoid, scalene, intercostal, and abdominal muscles are crucial when additional respiratory effort is required, such as during deep...
