Middle ear muscles have a common embryological and functional origin with masticatory and facial muscles. Therefore, symptoms referred to the ear may originate from the stomatognathic area. When a primary otological cause is discarded in the diagnostic work up for tinnitus, vertigo, hypoacousia, hyperacousia, ear pain or sensation of occluded ear, a temporomandibular joint dysfunction may be the cause of these symptoms. Temporomandibular joint dysfunction is twice more common among women and has environmental, physiological and behavioral causes. Among patients with this dysfunction, the prevalence of ear pain, tinnitus and dizziness varies between 33 and 76%

Middle ear cholesteatoma caused by repeated ear infections over time, destroys the delicate middle ear bones and causes permanent hearing loss or dizziness. It may grow to involve the facial nerve causing facial paralysis. In some instances, cholesteatomas can expand up into the brain, causing meningitis, sinus thrombosis, facial nerve palsy, vestibulitis and differently localized abscess. Nearly all patients with cholesteatoma require surgery to cure the disease. Therapeutic and rehabilitative surgical procedures were done, using either a closed technique (TCT) or an open technique: tympanoplasty in open technique (TOT). The aim of the work was to compare the advantages of TCT and TOT surgical technique for the treatment of cholesteatoma disease. The research was conducted in Tbilisi State Medical University Otorhino-laryngological Clinic on 65 patients with middle ear cholesteatoma: 21 women and 44 men in 2006-2008. Their average age was 29. The youngest was 7 years old, and the oldest one - 67. The investigation revealed that after TCT recidivations were noted in 16% of patients; after TOT in 42.3% of patients. It is concluded that CT technique is the most appropriate and optimal surgical interference for the treatment of chronic middle ear diseases.

Perilymphatic fistula (PLF) is defined as an abnormal leakage between perilymph from the labyrinth to the middle ear. Symptoms include hearing loss, tinnitus, and vertigo. The standard mode of PLF detection is intraoperative visualization of perilymph leakage and fistula, which ostensibly confirms the existence of PLF. Other possible methods of diagnosis include confirmation of pneumolabyrinth via diagnostic imaging. Recently, a cochlin-tomoprotein (CTP) detection test has been developed that allows definitive diagnosis of PLF-related hearing loss. We report the case of a 45-year-old man who presented with right-sided tinnitus, hearing loss, and dizziness 30 years after stapes surgery. Middle ear lavage was performed after myringotomy. A preoperative diagnosis of PLF was reached using the CTP detection test. Intraoperative observations included a necrotic long process of the incus, displaced wire piston, and fibrous tissue in the oval window. Perilymph leakage was not evident. The oval window was closed with fascia, and vertigo disappeared within 2 weeks postoperatively. When PLF is suspected after stapes surgery, the CTP detection test can be a useful, highly sensitive, and less invasive method for preoperative diagnosis.

The human body is well adapted to dealing with small variations in atmospheric pressure. However when our pursuit of sport and recreation takes us to extreme altitudes or ocean depths, the change in surrounding pressure has the potential to cause significant morbidity. Sports with more extreme changes in atmospheric pressure such as skydiving and scuba diving commonly place the athlete at risk for barotrauma injuries, especially in the middle ear and sinuses. Middle ear barotrauma occurs when a pressure differential develops between the middle ear and the pressure outside of the tympanic membrane. Early symptoms include ear pain, dizziness, and muffled hearing. When extreme pressure gradients are not relieved, middle ear effusions and rupture of the tympanic membrane can occur. A similar mechanism and injury pattern occurs in the sinuses as well. With proper training and prevention strategies, athletes in these sports can protect themselves from most barotrauma injuries.

Middle ear surgery is strongly influenced by anatomical and functional characteristics of the middle ear. The complex anatomy means a challenge for the otosurgeon who moves between preservation or improvement of highly important functions (hearing, balance, facial motion) and eradication of diseases. Of these, perforations of the tympanic membrane, chronic otitis media, tympanosclerosis and cholesteatoma are encountered most often in clinical practice. Modern techniques for reconstruction of the ossicular chain aim for best possible hearing improvement using delicate alloplastic titanium prostheses, but a number of prosthesis-unrelated factors work against this intent. Surgery is always individualized to the case and there is no one-fits-all strategy. Above all, both middle ear diseases and surgery can be associated with a number of complications; the most important ones being hearing deterioration or deafness, dizziness, facial palsy and life-threatening intracranial complications. To minimize risks, a solid knowledge of and respect for neurootologic structures is essential for an otosurgeon who must train him- or herself intensively on temporal bones before performing surgery on a patient.
