APPLIED ANATOMY OF MAXILLARY SINUS

FLOOR: OROANTRAL FISTULA: -MAXILLARY TEETH ARE IN DIRECT RELATION TO MAXILLARY SINUS FLOOR. TH E DISTANCE BETWEEN THE APICAL END OF MAXILLARY POST TOOTH WITH THE FLOOR OF MAXILLARY SINUS IS 11. 5 CM IN ADULTS. THIS DISTANCE IS MAX IN PAEDIATRIC GROUP < 15 YEARS OF AGE SO CHANCE OF ORO ANTRAL FISTULA IS LESS COMMOM IN THEM

CALDWELL LUC SURGERY: WALL OF MAXILLARY SINUS IS VERY THIN IN CANINE FOSSA REGION SO THIS IS AN IDEAL SITE FOR CALD WELL LUC SURGERY USED IN: 1. CHRONIC MAXILLARY SINUSITIS WITH IRREVERSIBLE CHANGES IN SINUS MUCOSA 2. SUSPECTED NEOPLASM IN THE ANTRUM & ITS BIOPSY 3. REMOVAL OF FOREIGN BODY OR ROOT OF TOOTH 4. ORO ANTRAL FISTULA & DENTAL CYST 5. RECURRENT A. C POLYP 6. # OF MAXILLA OR BLOW OUT # OF ORBIT 7. LIGATION OF MAXILLARY ARTERY

OROANTRAL FISTULA

MAXILLARY SINUSITIS: DENTAL CARIES , HALLUTOSIS, GUM BLEEDING MUST BE EXAMINED PROPERLY IN THE PATIENT HAVING MAXILLARY SINUSITIS AS DENTAL CARRIES OF MAXILLARY MOLARS MAY CAUSE ASCENDING INFECTION IN THE MAXILLARY SINUS MAXILLARY TENDERNESS: IS ELICITED BY PUTTING GENTLE PRESSURE OVER MAXILLARY CANINES.

ROOF TRAUMA/ BLOW OUT FRACTURE ORBITAL WALL OF M. S IS VERY FRAGILE SO ITS VULNENARABLE TO TRAUMA. IN SUCH CASES ORBITAL FAT MAY PROLAPSE IN SIDE THE MAXILLARY SINUS CAVITY & CAUSE ENOPTHALOUS, RESTRICTED EYE MOVEMENTS, LOSS OF SENSATION OVER I. O REGION, PERIORBITAL ECHYMOSIS DIPLOPIA GLAUCOMA EROSION : MAXILLARY SINUS TUMOR MAY ENLARGE IN SIZE & ERODE THE ORBITAL WALL LEADING TO EXOPTHALMOUS, CHEMOSIS & MAY HAMPER THE VISION

BLOW OUT # OF LEFT ORBIT

INFRA ORBITAL NERVE BLOCK INFRAORBITAL FORAMEN TRANSMITIING I. O NERVE & VESSELS LIES IN THE ORBITAL WALL/ ROOF OF MAXILLARY SINUS. BEING VERY FRAGILE IS VULNERABLE TO GET INJURED IN ANY ORBITAL/MAXILLARY TRAUMA I. O NERVE IS USED TO ACCOMPALISH REGIONAL ANAESTHESIA FOR FACE

INFRA ORBITAL NERVE BLOCK

ANTERIOR WALL OSTEOMYLIETIS: ANTERIOR WALL OF MAXILLARY SINUS IS VULNERABLE TO DEVELOP OSTEOMYELITIS & IS MORE OFTEN SEEN IN INFANTS & CHILDREN THAN ADULTS COZ OF PRESENCE OF SPONGY BONE IN ANTERIOR WALL OF SINUS. INFECTION ASCENDS FROM THE DENTAL SAC AND LESS OFTEN ITS PRIMARY INFECTION

& THEN SPREADS TO SUBPERIOSTEAL REGION FISTLA(I. O REGION, ALVEOLUS, PALATE OR IN ZYGOMA SEQUESTERISATION & BONE DEFORMITY

TO ELICIT THE TENDERNESS OF MAXILLARY SINUS BY TAPPING OVER THE LATERAL ASPECT OF ANTERIOR WALL I, e PROMINANCE OF CHEECK BONE AND INTRA ORAL PALPATION BETWEEN CANNINE FOSSA & ZYGOMATIC BUTTRESS.

PALPATION OF MAX SINUS

POSTERIOR WALL LIGATION OF MAXILLARY ARTERY IN CASE OF EPISTAXIS WHENCONSERVATIVE PROCEDURES ARE NOT HELPFUL , LIGATION OF MAXILLARY ARTERY IS REQUIRED. WHICH CAN BE APPROCHED THROUGH INTRA NASAL PATH INTO THE MAXILLARY SINUS WHERE WE CREATE A WINDOW IN ITS POSTERIOR WALL TO REACH MAXILLARY ARTERY TUMOR OF INFRATEMPORAL SPACE MAY ERODE POSTERIOR WALL OF MAXILLARY SINUS & INFILTERATE PARASYMPATHETIC GANGLION (S. P GANGLION) &

PT MAY PRESENT WITH DEEP FACIAL PAIN, HARD PALATE INSENSITIVITY & DECREASED LACRIMATIOM………

LIGATION OF MAXILLARY ARTERY

MAXILLARY CAVITY 1. PROOF PUNCTURE 2. HALLER CELLS 3. KARTAGENERS SYNDROME
