What is middle meatal antrostomy?
MIDDLE MEATAL ANTROSTOMY 1. Definition: Enlargement of the natural opening of the maxillary sinus into the middle meatus.
Does middle meatal antrostomy prevent the onset of maxillary sinusitis after zygomatic implant placement?
after placement of zygomatic implants. We hypothesized that middle meatal antrostomy might reduce the incidence of this complication. placement of 4 zygomatic implants and concurrent middle meatal antrostomy with an endoscopic approach at the maxillofacial surgery unit of Verona University.
What is maxillary antrostomy?
WHAT IS A MAXILLARY ANTROSTOMY? The maxillary sinuses are located under your cheekbones. When they become blocked and no longer drain properly, an infection can develop. Often, the sinus opening itself becomes blocked, too. The procedure to clear the sinus opening is called a maxillary antrostomy.
What is the middle meatus?
The middle meatus is an air passage of the lateral nasal cavity located between the middle nasal concha and lateral nasal wall. The anterior ethmoid air cells, maxillary and frontal sinuses all drain into the middle meatus.
What structures drain middle meatus?
Do sinuses drain into mouth?
A dental sinus may drain to: the inside of the mouth (an intraoral sinus), or, the skin surface of the face or neck (an extraoral, orofacial sinus).
What is the definition of Middle meatal antrostomy?
MIDDLE MEATAL ANTROSTOMY 1. Definition: Enlargement of the natural opening of the maxillary sinus into the middle meatus. 2. Indications: – Recurrent acute maxillary sinusitis.
Can a middle meatal antrostomy improve maxillary sinus function?
A statistically significant postoperative decrease of mucosal eosinophils, as well as the correlation of the intraoperative eosinophils with the postoperative symptom score, was found only on the antrostomy side. Surgery did not significantly improve the mucociliary function of the maxillary sinus
Where does local anesthetic go during maxillary antrostomy?
Dashed circles represent the ostiomeatal complexes. Local anesthetic should be infiltrated at both X s, which correspond to the axilla of the middle turbinate as it attaches to the lateral nasal wall, and injected into the anterior face of the middle turbinate itself.
When to amputate the middle turbinate in a maxillary antrostomy?
The middle turbinate serves to humidify inspired air. Care should be taken to preserve the middle turbinate if possible when performing a maxillary antrostomy. If removal is necessary, consider amputating only the anterior inferior quadrant of the turbinate. Identify the uncinate process and its relation to the medial orbital wall.
