Morphometric analysis of infraorbital foramen in Indian dry skulls

We analyzed the variability in position, shape, size and incidence of the infraorbital foramen in Indian dry skulls as little literature is available on this foramen in Indians to prevent clinical complications during maxillofacial surgery and regional block anesthesia. Fifty-five Indian skulls from the Department of Anatomy CSM Medical University were examined. The 110 sides (left and right) of the skulls were analyzed by measuring the infraorbital foramina distances from infraorbital margin and the piriform aperture on both sides. The vertical and horizontal dimensions were also measured. All measurements were taken with a compass transferred to calipers and analyzed statistically. The mean distances between the infraorbital foramen and the infraorbital margin on the right and left side were 6.12 mm and 6.19 mm, respectively. The mean distances between the infraorbital foramen and the piriform aperture were 15.31 mm and 15.80 mm on the right and left sides, respectively. The mean vertical dimensions on the right and left side were 3.39 mm and 3.75 mm, respectively. The mean horizontal dimensions on the two sides were 3.19 mm and 3.52 mm. These results provide detailed knowledge of the anatomical characteristics and clinical importance of the infraorbital foramina which are of paramount importance for surgeons when performing maxillofacial surgery and regional block anesthesia

Simultaneous miringoplasty and septoplasty, and the use of nasal septal perichondrium

8th International Conference on Cholesteatoma and Ear Surgery -- JUN 15-20, 2008 -- Antalya, TURKEYWOS: 000267661600008PubMed: 19125267To investigate the more ideal graft for optimal repair of tympanic membrane perforation, we examined the use of septal perichondrium in myringoplasty. Twenty-five patients with ages ranging between 18 and 54 were included in this study. All had a persistent, symptomatic tympanic membrane perforation, and nasal obstruction. All patients were scheduled for myringoplasty by a transmeatal approach in combination with septoplasty under general anaesthesia. Twenty-three patients had intact graft material and had more than 5 dB HL improvement in conductive hearing thresholds at least three frequencies in the follow up period. An overall success rate of 92 and 92% was recorded in terms of hearing improvement and perforation closure, respectively. Nasal septal perichondrium is easily accessible, cost-effective, time saving, sufficiently large, and patient friendly as a graft material in myringoplasty and has a good chance of postoperative survival

Unusual brain and temporal bone metastases of a botryoid type of embryonal nasopharyngeal rhabdomyosarcoma

We present a 2 year-old boy with a botryoid type of embryonal nasopharyngeal rhabdomyosarcoma with an unusual outcome. Temporal bone metastasis with brain invasion was detected one year after therapy had been completed. Despite multidisciplinary therapeutic approach, distant metastases occurred in the mastoid and squamous portions of the temporal bone with invasion of the temporal lobe. We review the clinical features of head and neck rhabdomyosarcoma and emphasize the importance of distant tumor metastasis. We believe that this tumor may spread to distant sites by different ways, and its biological course is typically fatal, particularly if recognized in advanced stages

Uncinate Process in the Repair of Nasoseptal Perforation

WOS: 000295844000027PubMed: 21455819Septal perforation is an anatomical defect of the nasal septum. Prior septal surgery is the most common reason of this defect. Because repair of a nasoseptal perforation is a challenging surgical procedure, many techniques have been discussed for decades. This article considers the first case of nasoseptal perforation repair using the overmedialized uncinate process. The main aim of this study is to report on the usability and efficiency of regional autogenous grafts in the repair of nasoseptal perforations

Anatomic variations of the sphenoid sinus on computed tomography

WOS: 000231432300007PubMed: 16008065Anatomic variations of the vital structures adjacent to the sphenoid sinus can be jeopardized during functional endoscopic sinus surgery (FESS). The knowledge of the size and extent of pneumatization of the sphenoid sinus (SS) is an important condition for adequate surgical treatment of its disease. The bony anatomic variations of SS as well as its relationship with adjacent vital structures were reviewed in this paper. The study was performed on 267 patients with a complaint of chronic or recurrent sinusitis. Computed tomographic (CT) scans were obtained upon completion of therapy. The evaluations of the sphenoid sinuses were regarded separately, so as 534 sides were examined. Especially bony anatomic variations as well as mucosal abnormalities of the sphenoid sinuses were examined. Pneumatization of the pterygoid process and anterior clinoid process were found in 39.7% and 17.2% of the patients respectively. Vidian canal protrusion was found in a total of 158 sides of which 60 were bilateral. These entities were encountered usually when pneumatization of the ptelygoid process occurred. Carotid canal and optic canal protrusions were found in 5.2% and 4.1% of the patients respectively. Mucosal thickening, and polyps or cysts of sphenoid sinuses were detected in 20.6% and 4.5% of the patients respectively. There was a statistically. significant correlation between pterygoid pneumatization and vidian canal protrusion (p < 0001), and vs. foramen rotundum protusion (p=0.004). While the optic canal protrusion was-found significantly associated with the anterior clinoid pneumatization (p < 0.001), there was no statistically significant correlation between a carotid canal protrusion and anterior clinoid pneumatization (p=0.250). Sphenoid sinus surgery is very risky, because of changing variations of the cavity. We are in the opinion that detailed data from CT scans of SS will enable the surgeon to interpret any anatomic variations and pathological conditions before initiation of the surgical therapy

Acoustic impedance study of peritubal myoclonus

WOS: 000177014200007PubMed: 12206259An audible clicking sound coexistent with the contractions of the peritubal muscles is thought to be an isolated form of palatal myoclonus that presents with myoclonal contractions of the soft palate, larynx, pharynx and, sometimes, cervicofacial area. Acoustic impedance measurements, by demonstrating the relation between the muscle contract ions and the clicking noise, represent one of the ways in which the diagnosis can be confirmed. This paper reports the impedance changes following various maneuvers and simultaneous electromyography recordings in four patients with peritubal myoclonus and confirms the accuracy and simplicity of these tests. The pathology of peritubal myoclonus and its treatment options are discussed

Acute actinic cheilitis-like chemical irritant reaction following accidental contact with ethylene glycol - Favorable response to topical 1% pimecrolimus cream: A case report

WOS: 000257028200005PubMed: 18568894Ethylene glycol is a colorless, odorless, nonvolatile, water-soluble fluid, mainly used as automobile antifreeze and coolant. This substance is a frequent culprit in accidental and intentional poisonings. Although potentially fatal systemic consequences of ethylene glycol ingestion are well known, local adverse effects through brief skin and mucosa contact with ethylene glycol have been rarely reported. Herein we report a patient with accidental ethylene glycol contact to the lower lip, who presented with acute, manifest, actinic cheilitis-like chemical irritant reaction and favorably responded to topical pimecrolimus 1% cream
