Manubrio-incudo-stapedioplasty for reconstruction of Austin-Kartush type B ossicular defects.

OBJECTIVE: Manubrio-incudo-stapedioplasty functional outcomes were compared to those of other methods for reconstructing Austin-Kartush type B ossicular defects. METHODS: Forty-two patients underwent Austin-Kartush type B ossicular defect reconstruction using: manubrio-incudo-stapedioplasty (13 patients), an autologous incus (19 patients) or a titanium ossicular replacement prosthesis (10 patients). For manubrio-incudo-stapedioplasty reconstruction, the malleus head was removed, the manubrium was relocated posteriorly and the incus short process was placed on the mobile footplate. The manubrium was placed on the incus body groove and bone cement was applied to stabilise the manubrium-incus junction. Pre- and post-operative hearing thresholds were assessed. RESULTS: The air-bone gap decreased from 25.9 ± 6.0 dB to 12.3 ± 5.0 dB (p < 0.05) in the manubrio-incudo-stapedioplasty group. The hearing gain was 13.6 ± 5.2 dB for manubrio-incudo-stapedioplasty, 3.4 ± 14.2 dB with the autologous incus, and 3.3 ± 11.07 dB with the titanium ossicular replacement prosthesis. Hearing improvement was greater for manubrio-incudo-stapedioplasty compared to the other reconstruction methods (p < 0.05). CONCLUSION: Manubrio-incudo-stapedioplasty resulted in satisfactory hearing outcomes in patients with Austin-Kartush type B ossicular defects. This technique can be considered a stable, inexpensive and effective method to reconstruct Austin-Kartush type B ossicular defects.

A case of unilateral mydriasis secondary to septoplasty under local anaesthesia.

Septoplasty is a procedure performed to correct deformities of the nasal septum. Serious complications associated with septoplasty include orbital complications. Here, we present a 26-year-old male patient who developed unilateral mydriasis while undergoing septoplasty under local anaesthesia. The mydriasis resolved spontaneously in an hour without any sequel. In the present study, we emphasise the orbital complications that can be observed during septoplasty.

A giant paediatric mandibular aneurysmal bone cyst and reconstruction with bilateral iliac bone graft.

A giant paediatric mandibular aneurysmal bone cyst and reconstruction with bilateral iliac bone graft. Aneurysmal bone cyst (ABC) is an unusual, non-neoplastic, expansile lesion of the bone. ABC is not a true cyst and it is characterised by the replacement of bone by fibro-osseous tissue containing blood-filled sinusoidal or cavernous spaces. The expanding mass often disrupts the normal bony architecture, with erosion of the cortex. Surgical treatment consists of complete excision or curettage. In this report, we present a 5-year-old girl with a huge aneurysmal bone cyst in the corpus of the mandible, which was reconstructed with bone graft taken from bilateral anterior iliac crests.

A case of concha pyocele (concha bullosa mucocele) mimicking intranasal mass.

Concha bullosa is the most common anatomic variant of the middle turbinate that usually remains asymptomatic. If the mucosal lining of pneumatized middle turbinate becomes inflamed, symptoms such as nasal obstruction, post-nasal discharge, snoring, headache, and fever occur. We report a case of concha pyocele (concha bullosa mucocele) in a 19-year-old girl. Computed tomography identified a right intranasal mass expanding towards the medial wall of the right maxillary sinus, nasal septum and right ethmoidal cells. The concha pyocele caused obstruction of the ostiomeatal complex, leading to right maxillary, ethmoid and sfenoid sinusitis. The patient was endoscopically treated under local anaesthesia. Histological examination of the mass revealed an active chronic inflammation caused by a foreign body.

A novel locus for autosomal recessive nonsyndromic hearing impairment, DFNB63, maps to chromosome 11q13.2-q13.4.

Hereditary hearing impairment is a genetically heterogeneous disorder. To date, 49 autosomal recessive nonsyndromic hearing impairment (ARNSHI) loci have been described, and there are more than 16 additional loci announced. In 25 of the known loci, causative genes have been identified. A genome scan and fine mapping revealed a novel locus for ARNSHI (DFNB63) on chromosome 11q13.2-q13.4 in a five-generation Turkish family (TR57). The homozygous linkage interval is flanked by the markers D11S1337 and D11S2371 and spans a 5.3-Mb interval. A maximum two-point log of odds score of 6.27 at a recombination fraction of theta = 0.0 was calculated for the marker D11S4139. DFNB63 represents the eighth ARNSHI locus mapped to chromosome 11, and about 3.33 Mb separate the DFNB63 region from MYO7A (DFNB2/DFNB11). Sequencing of coding regions and exon-intron boundaries of 13 candidate genes, namely SHANK2, CTTN, TPCN2, FGF3, FGF4, FGF19, FCHSD2, PHR1, TMEM16A, RAB6A, MYEOV, P2RY2 and KIAA0280, in genomic DNA from an affected individual of family TR57 revealed no disease-causing mutations.

Endoscopic view and MRI of a Thornwaldt's cyst of the nasopharynx.

A Thornwaldt's cyst is an uncommon nasopharyngeal lesion that develops from the remnant of the primitive notochord. A 65-year-old man with a Thornwaldt's cyst is presented in this case report. The patient was diagnosed by rigid nasal endoscopy and magnetic resonance imaging (MRI). These cases are infrequently presented in the English journals. Our study suggested that endoscopic and MRI examinations of the nasopharynx were a simple, rapid, and useful procedure for the diagnosis of the Thornwaldt's cysts.

Maxillary and temporal fibrous dysplasia: three cases.

PROBLEMS/OBJECTIVES: Fibrous dysplasia (FD) is a benign, expansile lesion of bone with slow progression and unknown origin. The purpose of this report is to make physicians aware of the symptoms, methods for differential diagnosis, and treatment options. METHODOLOGY: Three cases of monostotic FD are presented; two involving the maxillary sinus, and one in temporal bone. CT scans are the definitive diagnostic and follow-up method. Surgical approaches to alleviate the symptoms, including facial deformity, are described. RESULTS: FD went undiagnosed for three years in these patients. All three patients were relieved of the symptoms by limited surgery, and remained asymptomatic for up to two years after the surgery, with no signs of recurrence. CONCLUSIONS: Practitioners should be alert to the possibility of FD, particularly if patients develop narrowing of the ear canal, or progressive postauricular or maxillofacial enlargement. Minimal surgery to alleviate the symptoms is the treatment of choice.

Hairy tongue: a case report.

Hairy tongue or black hairy tongue is a benign condition characterized by hypertrophy of the filiform papillae that give the dorsum of the tongue a furry appearance. The color of the elongated papillae varies from yellowish white to brown or black. The etiology is unclear, but the disorder has been associated with numerous predisposing conditions such as heavy smoking, poor oral hygiene, use of topical or systemic antibiotics, systemic corticosteroid therapy, yeast infections, and radiotherapy for head and neck malignancies. A case is presented in which a hairy tongue appeared in a 67-year-old man.
