The most important diseases or complications that can be caused by a mouth-antrum connection (MAV) are:
Respiratory system (J00-J99)
- Sinusitis maxillaris (maxillary sinusitis).
Eyes and eye appendages (H00-H59).
- Inflammatory infiltration of the orbit (eye socket) as a complication of sinusitis maxillaris (maxillary sinus)
- Amaurosis (blindness) after inflammatory infiltration of the orbit in sinusitis maxillaris – thrombosis of the central retinal artery.
Infectious and parasitic diseases (A00-B99).
- Aspergilloma (local colonization and compartmentalization of a mold) of the maxillary sinus [with prolonged MAV].
- Scattering of pathogenic (“pathological”) bacteria in the blood and lymphatic circulation.
Mouth, esophagus (food pipe), stomach, and intestines (K00-K67; K90-K93).
- Abscess formation
- Ostitis (inflammation of the bone) of the jaw
- Osteomyelitis (bone marrow inflammation) of the jaw.
- Persistent oroantral fistula
Psyche – nervous system (F00-F99; G00-G99)
- Impairment of the IIIrd, IVth, and VIth cranial nerves [in thrombophlebitis/vein inflammation of the cavernous sinus].
- Inflammatory infiltration of the interior of the skull [as a complication of maxillary sinusitis].
- Epidural (“on the hard meninges“) infections.
- Subdural (“below the hard meninges”) infections
- Brain abscess
- Meningitis (meningitis)
- Infectious thrombosis of the sinus cavernosus
- Septic thrombophlebitis of the contralateral sinus cavernosus
Injuries, poisoning, and other sequelae of external causes (S00-T98).
- Dens in antro (“tooth in the (maxillary) sinus”).
- Radix in antro (“tooth root remnant in the (maxillary) sinus”).
Prognostic factors
- Operatively induced flattening of the vestibule (oral vestibule) after Rehrmannoplasty may necessitate preprosthetic vestibuloplasty.
- Displacement of teeth or tooth fragments into the maxillary sinus necessitates their intraoperative removal by irrigation and suction. Failure entails vestibular fenestration of the maxillary sinus.
- Closure of a prolonged oroantral junction is preceded by adequate treatment of sinusitis (sinus infection).
- Recurrence (recurrence of the disease) after Rehrmann plastic surgery entails a new surgical procedure with multilayer closure.
