Summary
Two-jaw surgery can cause vocal fold paralysis and laryngeal granulation due to intubation tube movement and swelling. Understanding these risks is crucial for managing pharyngeal complications after jaw corrective procedures.
Area of Science:
- Oral and Maxillofacial Surgery
- Otolaryngology
- Surgical Complications
Background:
- Two-jaw surgery corrects jaw deformities but poses a risk of pharyngolaryngeal injury.
- The exact causes of these postoperative complications remain unclear.
Purpose of the Study:
- To investigate the frequency and causes of pharyngeal complications after maxillary translocation surgery.
- To identify risk factors associated with vocal cord paralysis and laryngeal granulation.
Main Methods:
- A retrospective study of 133 two-jaw surgery cases (September 2019 - July 2022).
- Postoperative assessment of patients with hoarseness or pharyngeal discomfort using nasal endoscopy.
- Comparison of patients with and without pharyngeal lesions (vocal cord paralysis, laryngeal granulation).
Main Results:
- A statistically significant difference in sex ratio was observed between groups with and without vocal cord paralysis.
- No significant differences were found regarding laryngeal granulation between the groups.
- Mean age, operative time, and blood loss did not show significant differences between groups.
Conclusions:
- Vocal fold paralysis and laryngeal granulation are linked to mechanical irritation from the intubation tube during surgery.
- Perilaryngeal tissue compression from hematoma and edema also contributes to these complications.

01:23Chronic Pharyngitis
1.0K
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,...

171
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...

Esophageal perforations manifest in various clinical forms, influenced by factors such as the perforation's cause and location (cervical, intrathoracic, or intra-abdominal), the extent of contamination, and potential injury to adjacent mediastinal structures. The timing between the perforation occurrence and treatment initiation also affects the clinical presentation.

01:20Pharynx
1.2K
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...

Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
