Tympanoplasty after war blast lesions of the eardrum: retrospective study. (1/39)

AIM: To establish whether hearing loss after eardrum blast injury could be recovered by tympanoplasty performed immediately after injury and what material is the most suitable for eardrum closure. METHODS: Tympanoplasty was performed in 119 (a total of 181 injuries) out of 651 patients examined for blast injury of the ear between 1991 and 2000. The study included a total of 106 patients who underwent tympanoplasty: 51 patients with unilateral and 55 with bilateral blast eardrum rupture (a total of 161 injuries). Three different materials were used for eardrum rupture closure: temporal fascia in 81, perichondrium in 61, and heterograft in 19 cases. Injuries were divided in 4 groups, according to the time elapsed between the injury and tympanoplasty (0-20, 21-60, 61-180, and 181 days and more). Otomicroscopic finding, audiometry, and tympanometry were used for definitive evaluation of tympanoplasty outcome. RESULTS: Eardrum rupture was successfully closed with temporal fascia in 91%, perichondrium in 92%, and heterograft in 89% of the cases (p=0.429). There were no statistically significant differences in either values of postoperative air- bone gap (p=0.210) or in eardrum perforation closure rate (p=0.951) with respect to the time period between the injury and tympanoplasty. Also, there was no correlation between the postoperative air-bone gap and the number of days elapsed between the rupture and tympanoplasty (r=-0.037, p=0.641). CONCLUSION: Small ruptures of the eardrum should be left to heal spontaneously. The patients with subtotal and total rupture and rupture that did not heal spontaneously in three months should undergo tympanoplasty. Temporal fascia, perichondrium from tragus, and heterograft are equally acceptable materials for eardrum closure after blast injury.  (+info)

Inner ear damage in children due to noise exposure from toy cap pistols and firecrackers: a retrospective review of 53 cases. (2/39)

This retrospective study presents the findings of inner ear damage documented in 53 children exposed to impulsive sound emitted by toy weapons and firecrackers. There were 49 boys and four girls aged between four and fourteen years. Thirty-nine children were affected unilaterally while fourteen had bilateral hearing loss (total of 67 ears). Most of the hearing loss (>70%) was sensorineural high frequency hearing loss, while only nine out of the 67 injured ears had sensorineural mid frequency hearing loss. Seven children sustained a traumatic ear drum perforation. Dizziness or tinnitus was reported by twenty children, with pathological ENG findings in four of them. This paper re-emphasizes the possibility of inner ear damage in children from exposure to noisy toys.  (+info)

Benefits of swimming pools in two remote Aboriginal communities in Western Australia: intervention study. (3/39)

OBJECTIVE: To determine the health impact of swimming pools built with the aim of improving quality of life and reducing high rates of pyoderma and otitis media. DESIGN: Intervention study assessing prevalence of ear disease and skin infections before and at six monthly intervals after opening of swimming pools. SETTING: Two remote Aboriginal communities in Western Australia. PARTICIPANTS: 84 boys and 78 girls aged < 17 years. MAIN OUTCOME MEASURES: Changes in prevalence and severity of pyoderma and perforation of tympanic membranes with or without otorrhoea over 18 months after opening of pools. RESULTS: In community A, 61 children were seen before the pool was opened, and 41, 46, and 33 children were seen at the second, third, and fourth surveys. Equivalent figures for community B were 60, 35, 39, and 45. Prevalence of pyoderma declined significantly from 62% to 18% in community A and from 70% to 20% in community B during the 18 months after the pools opened. Over the same period, prevalence of severe pyoderma fell from 30% to 15% in community A and from 48% to 0% in community B. Prevalence of perforations of the tympanic membrane fell from 32% in both communities to 13% in community A and 18% in community B. School attendance improved in community A. CONCLUSION: Swimming pools in remote communities were associated with reduction in prevalence of pyoderma and tympanic membrane perforations, which could result in long term benefits through reduction in chronic disease burden and improved educational and social outcomes.  (+info)

Traumatic perilymph fistula in infants: a case report. (4/39)

Traumatic perilymph fistula is reported to be rare in infants because of the small size of the infant external meatus. We treated an infant with a traumatic perilymph fistula in the right ear. A metallic wire had penetrated the tympanic membrane. Horizontal-rotatory nystagmus was also observed. Computed tomographic images revealed dislocation of the ossicles. The perilymph fistula was closed under general anesthesia. The incus-stapes joint was separated and the footplate of the stapes was dislocated. Leakage of the perilymph fluid was apparent from the oval window and this fistula was closed with connective tissue. The perforation of the tympanic membrane was closed with temporal fascia. After surgery, the spontaneous nystagmus disappeared. The patient is under observation as an outpatient and is growing normally.  (+info)

Progressive calvarial and upper cervical pneumatization associated with habitual valsalva maneuver in a 70-year-old man. (5/39)

A 70-year old man with a 15-year-history of chronic daily Valsalva maneuvers for left ear congestion presented with worsening vertigo and calvarial (occipitoparietal) and upper cervical hyperpneumatization. With continued frequent Valsalva maneuvers, subsequent studies demonstrated increased pneumatization with extension of air into the epidural space, causing mass effect on the left parietal lobe. Four months after discontinuing the habitual Valsalva maneuvers, CT demonstrated resorption of the epidural air and partial regression of the calvarial pneumatization.  (+info)

The clinical course of acute otitis media in high-risk Australian Aboriginal children: a longitudinal study. (6/39)

BACKGROUND: It is unclear why some children with acute otitis media (AOM) have poor outcomes. Our aim was to describe the clinical course of AOM and the associated bacterial nasopharyngeal colonisation in a high-risk population of Australian Aboriginal children. METHODS: We examined Aboriginal children younger than eight years who had a clinical diagnosis of AOM. Pneumatic otoscopy and video-otoscopy of the tympanic membrane (TM) and tympanometry was done every weekday if possible. We followed children for either two weeks (AOM without perforation), or three weeks (AOM with perforation), or for longer periods if the infection persisted. Nasopharyngeal swabs were taken at study entry and then weekly. RESULTS: We enrolled 31 children and conducted a total of 219 assessments. Most children had bulging of the TM or recent middle ear discharge at diagnosis. Persistent signs of suppurative OM (without ear pain) were present in most children 7 days (23/30, 77%), and 14 days (20/26, 77%) later. Episodes of AOM did not usually have a sudden onset or short duration. Six of the 14 children with fresh discharge in their ear canal had an intact or functionally intact TM. Perforation size generally remained very small (<2% of the TM). Healing followed by re-perforation was common. Ninety-three nasophyngeal swabs were taken. Most swabs cultured Streptococcus pneumoniae (82%), Haemophilus influenzae (71%), and Moraxella catarrhalis (95%); 63% of swabs cultured all three pathogens. CONCLUSION: In this high-risk population, AOM was generally painless and persistent. These infections were associated with persistent bacterial colonisation of the nasopharynx and any benefits of antibiotics were modest at best. Systematic follow up with careful examination and review of treatment are required and clinical resolution cannot be assumed.  (+info)

Health issues for surfers. (7/39)

Surfers are prone to acute injuries as well as conditions resulting from chronic environmental exposure. Sprains, lacerations, strains, and fractures are the most common types of trauma. Injury from the rider's own surfboard may be the prevailing mechanism. Minor wound infections can be treated on an outpatient basis with ciprofloxacin or trimethoprim-sulfamethoxazole. Jellyfish stings are common and may be treated with heat application. Other treatment regimens have had mixed results. Seabather's eruption is a pruritic skin reaction caused by exposure to nematocyst-containing coelenterate larvae. Additional surfing hazards include stingrays, coral reefs, and, occasionally, sharks. Otologic sequelae of surfing include auditory exostoses, tympanic membrane rupture, and otitis externa. Sun exposure and skin cancer risk are inherent dangers of this sport.  (+info)

Otitis media in young Aboriginal children from remote communities in Northern and Central Australia: a cross-sectional survey. (8/39)

BACKGROUND: Middle ear disease (otitis media) is common and frequently severe in Australian Aboriginal children. There have not been any recent large-scale surveys using clear definitions and a standardised middle ear assessment. The aim of the study was to determine the prevalence of middle ear disease (otitis media) in a high-risk population of young Aboriginal children from remote communities in Northern and Central Australia. METHODS: 709 Aboriginal children aged 6-30 months living in 29 communities from 4 health regions participated in the study between May and November 2001. Otitis media (OM) and perforation of the tympanic membrane (TM) were diagnosed by tympanometry, pneumatic otoscopy, and video-otoscopy. We used otoscopic criteria (bulging TM or recent perforation) to diagnose acute otitis media. RESULTS: 914 children were eligible to participate in the study and 709 were assessed (78%). Otitis media affected nearly all children (91%, 95%CI 88, 94). Overall prevalence estimates adjusted for clustering by community were: 10% (95%CI 8, 12) for unilateral otitis media with effusion (OME); 31% (95%CI 27, 34) for bilateral OME; 26% (95%CI 23, 30) for acute otitis media without perforation (AOM/woP); 7% (95%CI 4, 9) for AOM with perforation (AOM/wiP); 2% (95%CI 1, 3) for dry perforation; and 15% (95%CI 11, 19) for chronic suppurative otitis media (CSOM). The perforation prevalence ranged from 0-60% between communities and from 19-33% between regions. Perforations of the tympanic membrane affected 40% of children in their first 18 months of life. These were not always persistent. CONCLUSION: Overall, 1 in every 2 children examined had otoscopic signs consistent with suppurative ear disease and 1 in 4 children had a perforated tympanic membrane. Some of the children with intact tympanic membranes had experienced a perforation that healed before the survey. In this high-risk population, high rates of tympanic perforation were associated with high rates of bulging of the tympanic membrane.  (+info)

Tympanic membrane perforation, also known as a ruptured eardrum, is a tear or hole in the tympanic membrane, which separates the outer ear canal and the middle ear. The tympanic membrane plays a crucial role in hearing by transmitting sound vibrations from the outer ear to the inner ear. A perforation can result from various causes such as infection, trauma, pressure changes, or explosive blasts, leading to symptoms like hearing loss, tinnitus, vertigo, and ear discharge. The extent and location of the perforation determine the severity of the symptoms and the course of treatment, which may include observation, antibiotics, or surgical repair.

Tympanoplasty is a surgical procedure performed to reconstruct or repair the tympanic membrane (eardrum) and/or the small bones of the middle ear (ossicles). The primary goal of this surgery is to restore hearing, but it can also help manage chronic middle ear infections, traumatic eardrum perforations, or cholesteatoma (a skin growth in the middle ear).

During the procedure, a surgeon may use various techniques such as grafting tissue from another part of the body to rebuild the eardrum or using prosthetic materials to reconstruct the ossicles. The choice of technique depends on the extent and location of the damage. Tympanoplasty is typically an outpatient procedure, meaning patients can return home on the same day of the surgery.

The tympanic membrane, also known as the eardrum, is a thin, cone-shaped membrane that separates the external auditory canal from the middle ear. It serves to transmit sound vibrations from the air to the inner ear, where they are converted into electrical signals that can be interpreted by the brain as sound. The tympanic membrane is composed of three layers: an outer layer of skin, a middle layer of connective tissue, and an inner layer of mucous membrane. It is held in place by several small bones and muscles and is highly sensitive to changes in pressure.

Otoscopy is a medical examination procedure used to evaluate the external auditory canal and tympanic membrane (eardrum). It involves the use of an otoscope, a tool that consists of a lighted speculum attached to a handle. The speculum is inserted into the ear canal, allowing the healthcare provider to visualize and inspect the eardrum for any abnormalities such as perforations, inflammation, fluid accumulation, or foreign bodies. Otoscopy can help diagnose various conditions including ear infections, middle ear disorders, and hearing loss.

The maxillary sinuses, also known as the antrums of Highmore, are the largest of the four pairs of paranasal sinuses located in the maxilla bones. They are air-filled cavities that surround the nasolacrimal duct and are situated superior to the upper teeth and lateral to the nasal cavity. Each maxillary sinus is lined with a mucous membrane, which helps to warm, humidify, and filter the air we breathe. Inflammation or infection of the maxillary sinuses can result in conditions such as sinusitis, leading to symptoms like facial pain, headaches, and nasal congestion.

Intestinal perforation is a medical condition that refers to a hole or tear in the lining of the intestine. This can occur anywhere along the gastrointestinal tract, including the small intestine, large intestine (colon), or stomach. Intestinal perforation allows the contents of the intestines, such as digestive enzymes and bacteria, to leak into the abdominal cavity, which can lead to a serious inflammatory response known as peritonitis.

Intestinal perforation can be caused by various factors, including:

* Mechanical trauma (e.g., gunshot wounds, stab wounds)
* Inflammatory bowel disease (e.g., Crohn's disease, ulcerative colitis)
* Diverticulitis
* Appendicitis
* Intestinal obstruction
* Infections (e.g., typhoid fever, tuberculosis)
* Certain medications (e.g., nonsteroidal anti-inflammatory drugs, corticosteroids)
* Radiation therapy
* Ischemic bowel disease (lack of blood flow to the intestines)

Symptoms of intestinal perforation may include sudden abdominal pain, nausea, vomiting, fever, and decreased bowel movements. Treatment typically involves surgery to repair the perforation and remove any damaged tissue. Antibiotics are also administered to prevent infection. In severe cases, a temporary or permanent colostomy or ileostomy may be necessary.
