Secretory otitis media Shankai YinProf Dept of Otolaryngology, the sixth hospital affiliated to Shanghai jiaotong university Otolaryngology institute at Shanghai jiaotong university
Denomination • Otitis media with effusion • Exudative otitis media • Mucoid otitis media • Catarrhal otitis media • Tubotympanitis • Non-suppurative otitis media………… • Secretory otitis media 1991 我国自然科学名词审定委员会
Pathology • Middle ear effusion • Serofluid、Mucus、Sero-mucous,non blood or CSF • Epithelium mucosae thicken,Epithelial metaplasia • Pseudostratified columnar ciliated epithelium Secretory epithelium
Epidemiology • Main in children • 5.2-21.6%(by aural speculum,Hongkong),7.3-30.7%(by acoustic impedance,Hongkong)in 2-7 year-old • 15-40%(2004,USA)in 1-5 year-old • 3.8%in 2 year-old,1.1% in 11 year-old(Suarez Nieto,1983,USA) • More than 50% infant occurs,most natural cure in 3 months
Etiology • Eustachian tube dysfunction • Eustachian tube blockage • Ciliary dysfunction • Infection • Immune reaction
Eustachian tube dysfunction • Disease in pharynx nasalis • Adenoidal hypertrophy • Nasopharyngeal carcinoma • Tumour from parapharyngeal space
Eustachian tube dysfunction • Circumflexus palati、levator palati weak • Cartilage of eustachian tube problem
Eustachian tube dysfunction • Rhinosinusitis • Nasal polypus
Infection • Germ in excretion of mid ear(Senturia,1958) • 22-52% positive in excretion of mid ear • Hemophilies influenzae (14.7%,USA)and micrococcus pneumoniae (7.0%,USA)are the main pathogenic bacterium • Also influenzavirus、adenovirus、chalmdiae trachomatis
Immune reaction • Type I • Allergic rhinitis • Nasal polyp • Bronchial asthma • Type III • Bacterium in adenoid and pharynx oralis
Clinical manifestation • Common cold • Hearing disturbance • Earache • Fural fullness • Tinnitus
Objective sign • Deaphragma auris • Hyperemia • Invagination • Mobility diminished • Cavum tympani • Fluidify • Air bubble
Objective sign • Pure tone test • Conductive hearing loss
Objective sign • Combined deafness deafness • Bacterium or toxin reach inner ear by RWM • HC hurt
Objective sign • Acoustic impedance • Type B:typical plot • Type C:eustachian tube dysfunction
Differential diagnosis • Nasopharyngeal carcinoma • Single secretory otitis media,adult,lump in neck,epistaxis • Epipharyngoscope,CT,MRI • Cerebrospinal otorrhea • Trauma or congenital deafness • Temporal bone CT
Differential diagnosis • Perilymphorrhea • Stapes operation,sudden deafness • Tullio phenomenon • Cholesterol granuloma • Sequela of secretory otitis media • Dark blue eardrum • Temporal bone CT
Treatment • Spontaneous cure • Etilogical treatment • Adenoidectomy • Amygdalectomy • FESS • Explorative tympanotomy
Treatment • Drug treatment • Antibiotic • Glucocorticosteroid • Decongestant • Ambroxol
Treatment • Eustachian tube inflation
Treatment • Paracentesis tympani Both diagnosis and treatment
Treatment • Paracentesis tympani • Surface anesthesia • Only adult • Asepsis • Complication • infection, • impairment of RWM • auditory ossicle • fenestration oval window
Treatment • Myringotomy • Cutter knife • Carbon • Dioxide laser
Treatment • Grommet insertion
Treatment • Grommet insertion • Indication • inefficacy of myringotomy • glue ear • hearing loss :40db • Complication • Tympanosclerosis • Permanence perforation of ear drum • Chronic suppurative otitis media • Sensorineural deafness
