OMM 14- Sinusitis and Otitis Media Anatomy Eustachian tubes empty out into the posterior-oropharynx. Several muscles attach to the eustachian tube and play a role in opening the tubes orifice. In newborns the eustachian tube has a more horizontal approach. It isn’t until approximately 6 years of age that the tube takes on a more vertical or anterior-inferior or declined orientation. Tube is closed / collapsed at rest Opens by action of tensor veli palatini and levator veli palatini (Muscles in nasopharynx) Levator Veli Palatini Innervation: CN X soft palate - functionally helps to seal nasopharynx from oropharynx Function: opens orifice of eustacian tube Tensor Veli Palatini Innervation: branches of the trigeminal nerve Function: tenses the soft palate, which opens the eustachian tube Parasympathetics OA AA Sphenopalantine Ganglion Parasympathetic to nasopharyngeal mucosa travel by way of the Facial n. They synapse in the Sphenopalantine ganglion Sympathetics Physiologic effects ◦ Vasoconstriction leading to Reduced lymphatico-venous drainage Reduced nutrient supply to the tissues Dryness “cracking” of mucosal lining ◦ Increased goblet cells with continued sympathetic activity Thick, sticky respiratory secretions ◦ Pt is left with thick, sticky secretions and reduced capacity to drain sinuses and reduced capacity to repair damage. OMM 14- Sinusitis and Otitis Media Chapman’s Points Anterior › Sinusitis : First ICS along superior margin of rib 2 mid-line b/w mid-clavicular line and sternum › Middle ear: Superior aspect of clavicle, about 1-2 cm from SC junction. Posterior › Sinusitis Nasal: lateral mass of C1 Sinuses: C2 just lateral of spinous process › Middle ear: C1, postero-lateral aspect Development of Sinusitis Maxillary and Ethmoid sinuses are present at birth. Frontal sinuses develop by around age 5 or 6. Sphenoid sinuses develop around age 8 to 10. Function Provide fluidity and mucus to upper airways Vehicle for protecting against various organisms.

Erythromycin does not provide adequate coverage. Trimethoprim/sulfamethoxazole has significant pneumococcal resistance. Levofloxacin is an option in resistant infections.

CT scan- Study of choice. They should be performed in patients that you are considering for surgery, in patients that aren’t responding to treatment, and in patients that worrisome findings are considered.

OMM 14- Sinusitis and Otitis Media Otitis Media Inflammatory reaction to foreign antigens in the middle ear that cannot adequately drain via the eustachian tube. Epidemiology Roughly 1 ½ occurrences per year in average child. 2nd hand smoke and daycare increase risk 3-5 times. Age < 2 years is most common. Older than 5 years of age occurrences should decrease. Usually less often in summer. Males > females Color appearance- Erythematous or yellow Bulging tympanic membrane in acute illness Often retracted in chronic infection Some patients may have hearing deficit during time of infection Decreased mobility with pneumatic otoscopy, especially in otitis media with effusion Organisms Moraxella catarrhalis H. Influenzae Strep pneumoniae Treatment Antihistamines and decongestants aren’t usually effective if the patient has a true infection. Amoxicillin- high dose in children Cefuroxime Cefdinir Ceftriaxone can be used in highly resistant patients OMT Treatment Cervical chain drainage Auricular drainage technique Galbreath Technique In-depth discussion in lab.
