Reconstruction of radical mastoid cavities: methods and results.

The radical mastoid cavity can be troublesome and odoriferous, may require frequent visits to an otologist, and may interfere with swimming and showering. Three procedures can be used to reconstruct the radical mastoid cavity. Soft tissue obliteration with autograft bone paste is the most versatile and commonly used technique. Reconstruction with homograft external auditory canal bone is useful for extremely large mastoid cavities that are free of infection. Use of these techniques in 35 patients since 1969 has resulted in dry, trouble free ears and improved hearing when reconstruction of the ossicular chain was performed. Use of this technique has helped patients with radical mastoid cavities to return to a normal active life style.

[Mastoid osteomas: review of literature and presentation of 2 clinical cases].

The authors report two cases of mastoid osteoma in patients at the "S. Filippo Neri" Hospital in Rome, Italy. The literature on this topic is critically reviewed. This review includes the 48 cases between 1875 and 1955 reported by Kecht, as well as the 92 cases Probst reported in 1991 in a review running from 1861. The literature published since 1991 has presented eight cases which, when added to the two presented here and the 92 indicated by Probst, total 102 cases of mastoid osteoma. The most widely accepted theories on the etiopathogenesis of mastoid osteoma are presented. These include: embryogenesis, metaplasia, inflammation, and trauma. The conclusions underline the complications of this disorder which are mainly linked to osteoma growth, and the importance of the differential diagnosis with other mastoid lesions for which prognosis is poorer.

The incidence and localization of mastoid foramen and superficial parietomastoid canal and their relations with each other.

Mastoid foramen and some superficial bony canal on the outer surface of the mastoid region are of importance not only as an epigenetic variation but because of the vessels passing through it as well. On the other hand such a canal structure has not been described in classical anatomy textbooks. In this study, the presence, localization and number of both mastoid foramen and superficial bony canal and their relations with each other were studied in 358 male, 228 female, a total of 586 dry Anatolian skulls. The mastoid foramen was absent in 21.5% of the skulls. In its presence it was mostly seen on temporal bone. A superficial bony canal was observed in 45% of the skulls. Some correlations were also observed between the above mentioned structures.

Elevation of a constructed auricle using the anteriorly based mastoid fascial flap.

Two-stage methods for reconstruction of congenital microtia have been widely utilised. To obtain a desirable auriculocephalic angle and provide a nutrient support to the constructed auricle, elevation of reconstructed ears using a costal cartilage graft, the anteriorly based mastoid fascial flap transfer and a skin graft was performed as the second operation for nine microtia patients. In this procedure, the mastoid fascial flap was used instead of the temporoparietal fascial flap. Following the elevation of the reconstructed ear the anteriorly based mastoid fascial flap was harvested. A carved costal cartilage was grafted at the posterior wall of the concha and covered with the mastoid fascial flap, followed by a full-thickness skin graft from the inguinal region. The skin grafts took well and the appropriate auriculocephalic angle was preserved in all cases. This method was easy to perform and did not leave any scar in the temporal hair-bearing area.

Acute mastoiditis. Diagnosis and complications.

Thirty children with acute mastoiditis were identified over a 12-year-period and their hospital records were reviewed retrospectively. All had abnormal tympanic membranes and 26 (87%) had swelling above or posterior to the ear that deviated the pinna. Findings on mastoid roentgenograms included clouding (n = 12) and osteitis (n = 7); six were normal. From 13 patients, bacteria were recovered from normally sterile sites and included Pneumococcus (n = 5), group A streptococcus (n = 3), Haemophilus (n = 2), and anaerobes (n = 3). Complications occurred in 13 children, including subperiosteal abscess (n = 7), meningitis (n = 4), osteitis (n = 7), facial palsy (n = 1), and subdural empyema and brain abscess (n = 1). Four of the six children with neurological complications had no external signs of acute mastoiditis on physical examination. Overall, 19 (63%) of the children recovered without mastoidectomy. We conclude that children without meningitis or subperiosteal abscess may be treated initially with antimicrobial therapy plus myringotomy. The need for mastoidectomy should be reassessed in children who fail to respond in 24 to 48 hours.

Surgical control of the mastoid segment in chronic ear disease in 1988.

The basic surgical guidelines for mastoid segment control are described in chronic ear disease. Dense cortical bone paté and mastoid tip bone chips are collected for possible obliteration of the surgical cavity produced. A meatally based musculoperiosteal flap is raised if "canal wall-down" surgery is anticipated. Mastoid bone surgery must be meticulous and the sigmoid, cerebellar and dural plates are first exposed. This is followed by a perilabyrinthine dissection. Tympanic or epitympanic surgery is connected with mastoidectomy as needed. All cavities are then obliterated.

Fungal mastoiditis in an immunocompetent adult.

Manifest fungal infection of the middle ear, fungal mastoiditis, is a very rare entity, which is almost exclusively seen in immunocompromised patients. The authors present a case of fungal mastoiditis in a 52-year-old woman without immunocompromise. The patient presented with acutely progressing symptoms of hearing loss and dysequilibrium. Bony fistula of the semicircular canal was noted on CT scans and a marginal perforation of the tympanic membrane was also seen. Her hearing recovered following the surgery, which revealed massive granulations and proliferation of fungi but no cholesteatoma in the mastoid cavity. Fungal infection of the middle ear is rare, but can cause serious complications. The possibility should be considered even in immunocompetent patients.

Indications for surgery in acute mastoiditis and their complications in children.

OBJECTIVE: To review the clinical charts of 45 paediatric patients treated for acute otomastoiditis at the ORL Department of the University of Brescia (Italy) between January 1994 and March 2005 and to discuss the diagnostic workup and the outcome of treatment. METHODS: Twenty-six males and 19 females were admitted with acute mastoiditis and subperiosteal abscess. Thirteen of them (28.9%) presented an intracranial complication. Only three of them were not operated upon; one received a ventilation tube (VT); all the others underwent a mastoidectomy within 48-72 h. Twenty out of 32 uncomplicated mastoiditis were treated conservatively and the remaining 12 underwent myringotomy+/-VT, associated with a mastoidectomy in 9 cases. RESULTS: Antibiotics alone or with VTs achieved a full recovery in 28 out of 32 uncomplicated cases. Mastoidectomy resolved the disease in 13 patients (9 with complications). In severe complications, a canal wall down (CWD) (n=2) or an intact canal wall (ICW) mastoidectomy (n=7) were preferred, based on the extent of the lesions and the degree of hearing loss. All children recovered completely at 1 year follow-up. In the uncomplicated cases that were operated upon, the mean hospital stay was 7.8 days (versus 4.3 days for the conservative group). In children with intracranial complications the mean hospital stay was 12.8 days, significantly less than the four non-surgical patients, who remained hospitalized for an average of 18 days. CONCLUSION: Acute mastoiditis can fully recover with conservative treatment or myringotomy+VTs. Immediate surgical treatment is indicated for intracranial complications, if the neurological conditions are not critical. A simple mastoidectomy+/-tympanoplasty is warranted in: (1) exteriorization, if the child is older than 30 months or >15 kg of weight, (2) intracranial complications (combined with a neurosurgical procedure as needed) and (3) cholesteatoma or granulation tissue.

Outpatient management of acute mastoiditis with periosteitis in children.

Children with acute mastoiditis with periosteitis are conventionally hospitalized for parenteral antibiotics and/or surgical treatment. However, if possible, effective and safe outpatient treatment is desirable. During a 36-month period, outpatient parenteral antibiotic therapy (once daily i.m. ceftriaxone) was evaluated in 32 children with acute mastoiditis, with clinical evidence of periosteitis. Inclusion criteria included otomicroscopic evidence of acute otitis media (AOM), displacement of the pinna, retroauricular swelling, erythema and tenderness. The treatment consisted of wide myringotomy and administration of i.m. antibiotics. Daily visits, by a combined team of an otolaryngologist and pediatric infectious disease specialist, were considered essential. Fourteen children (43%) were treated initially in the hospital (and subsequently as outpatients) and 18 (57%) children were treated entirely as outpatients. Mean duration of outpatient treatment was 7 days (range: 4-10). The overall clinical cure rate was 96.8%. One child underwent simple mastoidectomy. No serious side effects were observed. Our data suggests that many children with acute mastoiditis with periosteitis can be managed successfully and safely as outpatients by a combined team of otolaryngologists and infectious disease specialists.

Bilateral facial palsy caused by bilateral masked mastoiditis.

Acquired simultaneous bilateral facial palsy caused by bilateral masked mastoiditis in a 25-month-old girl is reported. After the administration of antibiotics for 10 days for treatment of bilateral acute otitis media, overt signs of otitis media diminished as bilateral facial palsy ensued. For diagnosis of masked mastoiditis, brain magnetic resonance imaging was of significant value in our case. The findings in this case suggest that masked mastoiditis should be considered as a cause of bilateral facial palsy, as well as unilateral facial palsy.

Acute and latent mastoiditis in children.

During the period from 1974 to 1981, surgery for acute mastoiditis was performed on 12 ears, giving an annual incidence of 0.004 per cent among cases of acute otitis media. All ears made a full long-term recovery. The low incidence is ascribed to the world-wide early use of antibiotics. During the same period 52 ears with secretory otitis media (SOM) underwent mastoidectomy. Histologically extensive mastoid inflammation was found in 96 per cent. The changes appeared as formation of secretory cells and cysts, resorption of bone, and infiltration of soft tissues with both mononuclear cells and polymorphonuclear leucocytes. The number of SOM patients undergoing mastoid operations account for 1.4 per cent of the patients admitted to hospital because of SOM. Thirty-four ears (65 per cent) have healed during the follow-up period (mean 2.9 years), while the tympanostomy tube is still in place in 18 ears (35 per cent). In the latter group, factors causing oedema in the pharyngeal end of the Eustachian tube are apparently still present.

[Mastoiditis in childhood].

BACKGROUND: Despite new antibiotics mastoiditis in children still is a serious infection confronting the pediatrician and otolaryngologist with diagnostic and therapeutic problems. PATIENTS AND METHODS: In a retrospective study we reviewed the charts of 48 children who had a mastoidectomy from 1990 to 1995 in the Department of Oto-Rhino-Laryngology at the University of Essen. RESULTS: 60% of the patients presented with a retroauricular swelling, and a pathologic tympanic membrane was found in 89%. The erythrocyte sedimentation rate as the most valuable laboratory parameter was increased in 95% of cases. Larger osteodestructive lesions as a complication of mastoiditis could be predicted in three of ten cases by plain x-ray of the temporal bone. The most common bacteria to be isolated were Staphylococcus aureus, Streptococcus pneumoniae and Pseudomonas aeruginosa. CONCLUSION: Because of potential endocranial complications (10% in our patients) as well as difficult radiologic diagnosis of osteodestructive lesions by plain x-ray, we advocate mastoidectomy instead of a mere pharmacological therapy in the treatment of mastoiditis.

Indications for mastoidectomy in acute mastoiditis in children.

The objective of this study was to identify clinical features of acute mastoiditis in children that are indicative of the need for mastoidectomy. We performed a retrospective chart review of 40 children (20 male, 20 female) between 2 months and 12 years 9 months of age with a diagnosis of acute mastoiditis who were managed in our institution between July 1998 and June 2002. All patients received intravenous antibiotics; this was the only treatment in 14 patients (35%). Tympanostomy tubes were inserted in 22 patients, together with postauricular needle aspiration in 12 (30%), and incision and drainage of subperiosteal abscess in 10 (25%). Mastoidectomy was performed in 4 cases (10%), and cholesteatoma was found in 3. One other child was subsequently found to have cholesteatoma. We conclude that children who present with acute mastoiditis should undergo mastoidectomy if cholesteatoma is clinically suspected, or if extratemporal suppurative complications have occurred.

Acute mastoiditis: a review of 69 cases.

Sixty-nine cases of acute mastoiditis were managed at the Kaplan Hospital in Israel during a 10-year period. About two thirds (68%) recovered with conservative therapy consisting of wide myringotomy and intravenous antimicrobial therapy, usually ampicillin and cloxacillin. One third (22 patients) were managed surgically by complete mastoidectomy. Indications for surgery were subperiosteal abscess, based on clinical findings in 20 patients; one had septic fever that did not respond to antimicrobial therapy, and one had signs of meningeal irritation. Mastoid radiographs played no role in the decision to operate. Four cases of unsuspected epidural abscess were found, two behind intact tegmental bone. Acute mastoiditis develops mostly in ears that have not been immune to previous infections; thus the mucosal barrier is broken easily and osteitis occurs. Although with the advent of antimicrobial therapy the presentation and course of the disease are milder, the disease is still serious and potentially lethal.

Management of the draining open mastoid cavity.

Deafness, discharge, dizziness, and dependency partially define the discomforts of the patient with an open draining mastoid cavity. The open mastoid cavity remains a problem for some patients despite visits to numerous otolaryngologists. This report is based on outpatient and surgical management of more than 300 open draining mastoid cavities.

Acute mastoiditis. Influence of antibiotic treatment on the bacterial spectrum.

The work was undertaken to investigate the spectrum of bacteria responsible for acute mastoiditis and to find out whether it is affected by intake of antibiotics prior to surgical treatment. The records were reviewed of 22 children with acute mastoiditis in whom mastoidectomy had been performed and bacterial cultures obtained. Eleven of the patients had had antibiotic treatment prior to admission (9 penicillin V and 2 erythromycin). Streptococcus pneumoniae was found in 8 of the purulent discharges: Haemophilus influenzae, Streptococcus beta-hemolyticus and Staphylococcus aureus in 2 each; Proteus mirabilis, Pseudomonas pyocyaneus and a Bacteroides strain in 1 each, while five discharges-all from patients pretreated with antibiotics-yielded no growth. None of the 9 patients pretreated with penicillin V provided pure cultures of pneumococci or beta-hemolytic streptococci, while one or the other of these species was found in 8 of the 11 untreated patients. Gram-negative bacteria were found both among those with and those without antibiotic pretreatment. The data indicate that pneumococci and beta-hemolytic streptococci are more likely to cause mastoiditis than are the other pathogens found in acute otitis media, and that, when drained at operation, purulent discharges are often found to have been sterilized by the pre-operative antibiotic treatment.

Mastoid cells myiasis in a Saudi man: a case report.

We report here the case of myiasis of the mastoid cells in a 50-year old Saudi farmer. Eight larvae of suspected Calliphorid fly were extracted from his right mastoid at examination in the clinic. The larvae almost ate into his brain, using their powerful screw-shaped mouth parts. It is the first report of Calliphorid larvae affecting the mastoid cells from Saudi Arabia. The epidemiological and clinical implications of this finding are discussed below.

Chondromyxoid fibroma of the mastoid invading the occipital bone.

We describe a case of chondromyxoid fibroma of the mastoid bone extending along the occipital bone in a 48-year-old man. The presence of this tumor was heralded solely by aural fullness caused by otitis media with effusion. The tumor arose from the mastoid cavity, eroding the entire petrous portion, and invading the foramen magnum and jugular foramen. The occurrence of this tumor is exceedingly rare, and, to our knowledge, this is only the second article in the literature that describes a chondromyxoid fibroma of the mastoid region. The clinical appearance of this tumor and its light- and electron-microscopic findings are presented with reference to other articles.
