Transconjunctival incision for total maxillectomy--an alternative for subciliary incision.

A subciliary incision may be associated with various complications of the lower eyelid when it is used during a total maxillectomy. The use of the transconjunctival incision instead is an alternative in suitable patients. The records of 17 patients were reviewed in whom a transconjunctival incision was used during total maxillectomy. These included 13 in whom the Weber-Ferguson incision was used, and 4 who had a sublabial incision. There was mild conjunctival oedema in all the cases during the immediate postoperative period but it did not last for more than two days. Four patients had mild to moderate oedema of the lid that resolved within two days. One had mild ectropion with transient epiphora, which was caused by early removal of the medial canthal sutures. We found the approach to be cosmetically acceptable as it avoids a scar in the subciliary region. The transconjunctival incision can be used in place of the subciliary incision for lateral exposure during total maxillectomy. There are few complications associated with the lower lid, and it has good cosmetic results; if it is combined with a sublabial incision in suitable patients, the maxillectomy is virtually scar-free.

Apophysomyces elegans causing acute otogenic cervicofacial zygomycosis involving salivary glands.

Zygomycosis is an invasive, life threatening fungal infection that usually affects immunocompromised hosts. In the head and neck region, rhino-orbito-cerebral zygomycosis is more common than the cervicofacial variety. We report the first case of otogenic cervicofacial zygomycosis caused by Apophysomyces elegans involving the salivary glands, an uncommon site of infection. The case began after a trivial trauma in a diabetic patient and despite surgical debridement and liposomal amphotericin B therapy, the patient died due to extensive involvement and metabolic/hemodynamic complications.

Multiple intraosseous hemangiomas-investigation and role of N-butylcyanoacrylate in management.

BACKGROUND: Primary intraosseous hemangiomas are rare (0.7% of all osseous neoplasms), benign, slow-growing neoplasms. These lesions are usually solitary. We are reporting a case of multicentric intraosseous hemangiomas. Investigation, treatment options, and role of N-butylcyanoacrylate (NBCA) in management will be discussed. METHODS AND RESULTS: A 20-year-old man had multicentric intraosseous hemangiomas involving the skull bones, mandible, vertebra, pelvic bone, and tibial tuberosity. N-butylcyanoacrylate was used by direct puncture technique using a transosseous transcutaneous route to control profuse bleeding from the retromolar region. CONCLUSION: To the best of our knowledge, this is the first reported case with such extensive multicentric intraosseous hemangiomas. N-butylcyanoacrylate by direct puncture technique can be an effective method to devascularize and stabilize low-flow intraosseous vascular tumors.

Unusual clinical and MRI features of a cerebellopontine angle medulloepithelioma. Case report and review of literature.

We describe for the first time an unusual location and clinical presentation of medulloepithelioma, a rare embryonal tumor. A 5-year-old child presented with sudden onset of bilateral hearing loss. On imaging, the lesion appeared to be extra axial and was located in the right cerebello-pontine (CP) angle, extending into middle fossa along the trigeminal ganglion and in front of the brain stem into the opposite CP angle. It did not show any enhancement following contrast administration and had restricted diffusion on diffusion-weighted imaging, simulating an epidermoid. However, in vivo localized proton MR spectroscopy revealed a creatine peak dominated by a large choline resonance, peak of glycine with lactate/lipid and invisible N-acetylaspartate suggestive of a neoplastic lesion and not an epidermoid. Only subtotal resection could be performed and the patient had a stormy post-operative course due to extensive dissemination of the disease.

Staging and surgical approaches in large juvenile angiofibroma--study of 95 cases.

INTRODUCTION: Surgery has been the treatment of choice for juvenile nasopharyngeal angiofibroma (JNA) and selection of proper surgical approach depends primarily upon the extensions of the tumor. Minimal external deformity/surgical scar without affecting growth pattern of facial skeleton of patient along with extensions of JNA were the basis of selecting surgical approach in present study. MATERIAL AND METHODS: The medical records of 95 patients with histologically proven large JNA who underwent treatment in our institution between 1992 and 2002 were reviewed retrospectively. Inclusion criterion-Stage II, III, IV JNA, minimum available follow up of 2 years. Exclusion criterion-Stage I JNA, follow up of less than 2 years. Lazy S incision was used and combined transmaxillary and transpalatal removal of angiofibroma was done in most of the cases. RESULTS: Complete removal of JNA was achieved in 78 (82%) cases in single surgery. Residual tumor was found in 17 (18%) cases. CONCLUSIONS: Infratemporal, pterygopalatine, orbital and intracranial extensions of JNA (Stage IIIa and IIIb) can be removed by combined transpalatal and transmaxillary approach by Lazy S incision without producing any facial asymmetry or cosmetic defect. Conservative lateral infratemporal approach (type D1 approach) is required in very large lateral extensions or where JNA is extending intracranially through foramen ovale. Staged fronto-temporal craniotomy should be done in Stage IVa tumors (large intracranial extensions). In Stage IVb tumors (invading cavernous sinus), usually residual tumor remains which should be followed subsequently.

Sac surgery results as a function of preoperative distress level.

OBJECTIVE: To evaluate the postoperative status of the patients after endolymphatic sac decompression (ESD) for intractable unilateral definite Ménière's disease (MD) using the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) 1995 criteria and to discuss the current status of ESD in the management of MD, especially after the wide use of intratympanic administration of gentamicin for the treatment of intractable MD. STUDY DESIGN: Retrospective questionnaire-based analysis. METHODS: Thirty-nine patients who had undergone ESD between 1996 and May 2003 at Sanjay Gandhi Post Graduate Institute of Medical Sciences, Lucknow, India, were evaluated via a set format according to AAO-HNS 1995 guidelines. Their preoperative and postoperative data were compared. RESULTS: We found significant improvement in functional level scales (FLSs) in 84.6%, Class A vertigo control in 82%, and improved disability outcome in 87% of cases after surgery at a median postoperative follow-up of 29 months. All the patients showing significant improvement in FLS were preoperatively in scale 4 or more, and all the patients whose treatment failed were in scale 3 or less. CONCLUSION: We recommend continued use of ESD in indicated patients. We found a positive relation between preoperative distress level of the patient and postoperative improvement in FLSs; any such relationship should be investigated with a larger sample.

Primary aneurysmal bone cyst of coronoid process.

BACKGROUND: Aneurysmal bone cysts are relatively uncommon in the facial skeleton. These usually affect the mandible but origin from the coronoid process is even rarer. To the best of our knowledge, this is the first reported case of a coronoid process aneurysmal bone cyst presenting as temporal fossa swelling. CASE PRESENTATION: A 17 year old boy presented with a progressively increasing swelling in the left temporal region developed over the previous 8 months. An expansile lytic cystic lesion originating from the coronoid process of the left mandible and extending into the infratemporal and temporal fossa regions was found on CT scan. It was removed by a superior approach to the infratemporal fossa. CONCLUSION: Aneurysmal bone cyst of the coronoid process can attain enormous dimensions until the temporal region is also involved. A superior approach to the infratemporal fossa is a reasonable approach for such cases, providing wide exposure and access to all parts of the lesion and ensuring better control and complete excision.

Management of low-flow vascular malformations of upper aero digestive system-role of N-butyl cyanoacrylate in peroperative devascularization.

OBJECTIVES: Low-flow vascular malformations of upper aero digestive system may cause difficulty in swallowing and/or breathing and bleeding from these lesions may even threaten the life of patient due to risk of aspiration. These lesions may require surgical resection with prior devascularization to minimize blood loss during surgery. METHODS: Peroperative devascularization of vascular malformations was carried in patients of our study group by injecting N-butyl cyanoacrylate (NBCA) into vascular malformations using direct puncture technique. This was followed by surgical resection of lesion in the same sitting. RESULTS: Successful devascularization of vascular malformations in all patients in our study group was achieved by injection of NBCA into the lesion by direct puncture technique. There was retraction of malformation due to devascularization, good plane of cleavage was found during subsequent surgical resection and blood loss was minimal. CONCLUSIONS: Low-flow vascular malformations of upper aero digestive system can be treated with surgical resection after peroperative devascularization. Direct puncture of NBCA into lesion under fluoroscopy control is an effective, safe and inexpensive method of devascularization which can be carried out by the surgeon in a single sitting.

Traumatic laryngotracheal stenosis--an alternative surgical technique.

Reconstruction of combined laryngotracheal stenosis requires complex techniques including resection and incorporation of grafts and stents that can be performed as single or multistaged procedure. A complicated case of traumatic laryngotracheal stenosis was managed by us, surgical technique is discussed. A 16-year-old male presented with Stage-3 laryngotracheal stenosis of grade-3 to 4 (>70% of the complete obstruction of tracheal lumen) of 5 cm segment of the larynx and trachea. Restoration of the critical functions of respiration and phonation was achieved in this patient by resection anastomosis of the trachea and with subglottic remodeling. Resection of 5 cm long segment of trachea and primary anastomosis in this case would have created tension at the site of anastomosis. So we did tracheal resection of 3 cm segment of trachea along with subglottic remodeling instead of removing the 5 cm segment of stenosed laryngotracheal region and doing thyrotracheal anastomosis. In complicated long segment, laryngotracheal stenosis, tracheal resection and subglottic remodeling with primary anastomosis can be an alternative approach. Fibrin glue can be used to support free bone/cartilage grafts in laryngotracheal reconstructions.

Cerebrospinal fluid otorhinorrhoea due to inner-ear malformations: clinical presentation and new perspectives in management.

OBJECTIVE: In children cerebrospinal fluid (CSF) otorhinorrhoea can be due to congenital inner-ear malformations. Cochlear dysplasia associated with a defect in the stapes footplate is usually the cause of the CSF leak. Repair of the CSF leak in these cases is usually done by packing the vestibule with muscle or fascia. This traditional method of repair has a 30 to 60 per cent failure rate. MATERIAL AND METHODS: CSF otorhinorrhoea due to congenital inner-ear anomalies in four patients was repaired using multiple-layer packing of the vestibule with glue, muscle and fascia, reinforced by a pedicle temporalis muscle graft. Intra-operatively, continous lumbar drainage was performed. RESULTS: Repair of the CSF leak was successful in four cases and no recurrence was noticed. Inner-ear magnetic resonance imaging (MRI) using three-dimensional fast-spin echo (3D FSE) T2-weighted imaging (T2WI) and 3D steady-state free precession (FIESTA) sequences was found to be a very helpful, noninvasive investigation to localize the site and route of the CSF leak. CONCLUSIONS: Children presenting with recurrent meningitis and CSF rhinorrhoea should be investigated for congenital inner-ear anomalies. In these cases CSF fistulae should be repaired using fibrin or cyanoacrylate glue and intra-operative continuous lumbar drainage; 3D FSE T2WI and 3D FIESTA MRI sequences of the inner ear are helpful.

Management of difficult airway in intratracheal tumor surgery.

BACKGROUND: Tracheal malignancies are usual victim of delay in diagnosis by virtue of their symptoms resembling asthma. Sometimes delayed diagnosis may lead to almost total airway obstruction. For difficult airways, not leaving any possibility of manipulation into neck region or endoscopic intervention, femorofemoral cardiopulmonary bypass can be a promising approach. CASE PRESENTATION: We are presenting a case of tracheal adenoid cystic carcinoma (cylindroma) occupying about 90% of the tracheal lumen. It was successfully managed by surgical excision of mass by sternotomy and tracheotomy under femorofemoral cardiopulmonary bypass (CPB). CONCLUSION: Any patient with recurrent respiratory symptoms should be evaluated by radiological and endoscopic means earlier to avoid delay in diagnosis of such conditions. Femorofemoral cardiopulmonary bypass is a relatively safe way of managing certain airway obstructions.

Cerebrospinal fluid otorhinorrhea due to cochlear dysplasias.

Cochlear dysplasia associated with defect in stapes footplate can be a cause of cerebrospinal fluid leak. Repair of cerebrospinal fluid leak in these cases is usually done by packing the vestibule with muscle or fascia. This traditional method of repair has 30-60% failure rate. Cerebrospinal fluid leak in four such patients was successfully repaired using multiple layer packing of vestibule, reinforced by pedicle temporalis muscle graft. Intraoperatively continuous lumbar drain was done. Magnetic resonance imaging of inner ear using 3D FSE T2WI and 3D FIESTA sequences was found helpful noninvasive investigation to localize site and route of cerebrospinal fluid leak.

Bilateral Ramsay Hunt syndrome in a diabetic patient.

BACKGROUND: Herpes zoster oticus accounts for about 10% cases of facial palsy, which is usually unilateral and complete and full recovery occurs in only about 20% of untreated patients. Bilateral herpes zoster oticus can sometime occur in immunocompromised patients, though incidence is very rare. CASE PRESENTATION: Diabetic male, 57 year old presented to us with bilateral facial palsy due to herpes zoster oticus. Patient was having bilateral mild to moderate sensorineural hearing loss. Patient was treated with appropriate metabolic control, anti-inflammatory drugs and intravenous acyclovir. Due to uncontrolled diabetes, glucocorticoids were not used in this patient. Significant improvement in hearing status and facial nerve functions were seen in this patient. CONCLUSIONS: Herpes zoster causes severe infections in diabetic patients and can be a cause of bilateral facial palsy and bilateral Ramsay Hunt syndrome. Herpes zoster in diabetic patients should be treated with appropriate metabolic control, NSAIDS and intravenous acyclovir, which we feel should be started at the earliest. Glucocorticoids should be avoided in diabetic patients.
