Endoscopic transcanal myringoplasty—A study

Aim of this study was to evaluate the role of rigid endoscope in the management of dry central perforation of the tympanic membrane and to compare the results of endoscopic myringoplasty with that of conventional myringoplasty using microscope. In endoscopic group there was 90% graft uptake rate as compared to 85% in microscopic group. The results of endoscopic myringoplasty are comparable to the conventional myringoplasty done under operating microscope and there is no significant difference between the gain in A-B gap in either group     

Endoscopic Endonasal Management of Pseudotumor Cerebri: Is it Effective?

PURPOSE: To study the efficacy and safety of endoscopic endonasal optic nerve fenestration for the management of idiopathic intracranial hypertension (IIH). DESIGN: A prospective study at a tertiary care center. PATIENTS AND METHODS: All patients with a final diagnosis of IIH from July 2001 to March 2005 were included and subjected to detailed neuro-ophthalmologic examination and endoscopic endonasal optic nerve fenestration. Postoperative visual acuity and the perimetry was compared with the preoperative status, and the results were analyzed using the chi2 test. RESULTS:: Of the 18 patients included in the study, 17 had improvement in vision postoperatively. Fifteen patients had visual deterioration in the other eye as well, and of these, 12 had improvement, obviating the need for surgery on the other side. Complications were minimal and in the form of synechiae in two of the cases. DISCUSSION: A number of procedures have been described for the management of this entity, and each is associated with a significant morbidity; therefore, there was a need for a minimally invasive procedure. The procedure adopted in the series is minimally invasive and is associated with a 94.5% success rate and minimal morbidity. CONCLUSIONS: Endoscopic endonasal optic nerve fenestration is a safe, minimally invasive, and extremely effective procedure for the management of IIH.     

Is Nasal Packing Necessary Following Endoscopic Sinus Surgery?

OBJECTIVES/HYPOTHESIS: To determine the necessity of nasal packing or hemostatic agents or both following endoscopic sinus surgery. STUDY DESIGN: Retrospective review of cases in a tertiary care sinus practice at an academic medical center. METHODS: Records of 165 patients undergoing 169 endoscopic sinus surgeries were reviewed to determine the presence of adjunctive nasal procedures, the use of nasal packing or hemostatic agents or both, blood loss during surgery, and the incidence of bleeding complications following surgery. RESULTS: The median estimated blood loss during surgery was 50.0 mL (range, 5-1000 mL). In four surgeries (2.4%) hemostatic agents were placed in the nose at the conclusion of surgery, 19 (11.2%) had packing, and 147 (87.0%) had no material left in the nose. No patients had bleeding complications postoperatively. There was a significant decrease in the use of packing or hemostatic agents or both over time. CONCLUSION: Placement of nasal packing or other hemostatic agents or both within the nasal cavity is not necessary in the majority of endoscopic sinus surgeries. The risks, costs, and discomforts associated with these interventions can often be avoided.     

Benign paroxysmal positional vertigo following whiplash injury: a myth or a reality?

Objective

The aim of the study was to evaluate the true incidence, diagnosis, and treatment of benign paroxysmal positional vertigo (BPPV) arising after whiplash injury and to distinguish this type of posttraumatic vertigo from other types of dizziness complained after trauma.

Methods

This was a retrospective study comprising patients referred to our center after whiplash injury. The patients were evaluated with neurotologic examination including bedside and instrumental tests. A Dizziness Handicap Inventory evaluating the symptoms of patients was submitted before and after treatment and was evaluated. The BPPV patients were separately evaluated from those with cervicogenic vertigo, and a comparison between our data about idiopathic BPPV was done.

Results

Eighteen patients of whiplash who had BPPV were evaluated. The mean age was 38.2 years. BPPV was the cause of vertigo in 33.9% of total whiplash patients. In 16 cases, the posterior semicircular canal was involved; the lateral semicircular canal was involved in 2 cases. The instrumental neurotologic assessment did not show any alteration of either vestibulospinal reflexes or dynamic ocular movements. Duration of symptoms before treatment ranged from 3 to 26 days. A total of 55.5% of patients had relief from their symptoms after first repositioning maneuver. The Dizziness Handicap Inventory score improved in all patients treated with repositioning maneuvers, but no difference emerged with idiopathic BPPV data.

Conclusion

BPPV after whiplash injury could be unveiled with a simple bedside examination of peripheral vestibular system, and a treatment could be done in the same session. The diagnosis of posttraumatic BPPV is not different from the idiopathic form, but the treatment may require more maneuvers to achieve satisfactory results.     

Endaural or postaural incision for myringoplasty: does it make a difference to the patient?

The aim of this study was to find out from patients who had undergone a myringoplasty via either an endaural or postaural approach whether or not they had experienced problems or symptoms relating to their scar, and if these differed depending on which incision had been used. A questionnaire was sent to 91 patients who had undergone myringoplasty between 18 and 62 months earlier. Thirty-four patients who had undergone previous or subsequent ear surgery were excluded. The only statistically significant difference found between groups having either a postauricular or endaural incision was in how likely others were to comment on their scar. There seem to be few long-term sequealae relating to the scar from myringoplasty. From a patient perspective, between 18 and 62 months postoperatively, there was very little difference in symptoms or problems whether or not an endaural or a postaural incision had been used for the surgery.

Calciphylaxis: Is There a Role for Parathyroidectomy?

OBJECTIVE: Calciphylaxis, a rare disorder typically affecting renal failure patients, results in vascular calcification with subsequent skin necrosis, gangrene, and often death from sepsis. Parathyroid hormone is thought to act as a tissue sensitizer leading to these soft tissue changes. As such, parathyroidectomy is often advocated to control this complicated condition. A discussion of calciphylaxis does not exist in the otolaryngology literature, and head and neck surgeons performing parathyroidectomy should be aware of this phenomenon. This study evaluates the success of parathyroidectomy in reversing the ill effects of calciphylaxis in both our patient population and the literature. STUDY DESIGN: Retrospective study and review of the literature. METHODS: Five patients with calciphylaxis treated at our institution were evaluated for mortality, surgical and perioperative complications, wound healing, and predictors of patient outcomes. RESULTS: Two patients died from sepsis and infectious complications of their calciphylaxis shortly after surgery. Of the three survivors, two later died (15 and 18 mo after surgery) from causes not directly related to calciphylaxis. The other long-term survivor required partial amputation of a leg for osteomyelitis. There was one operative complication-- wound infection requiring antibiotic therapy, drainage, and packing. Postoperative hypocalcemia required treatment in two patients. Immediate perioperative survival was more likely in patients with leukocyte counts less than 20,000 cells/mL CONCLUSIONS: Calciphylaxis is a serious disease and patients often succumb to sepsis and infectious complications. Patients with extremely high leukocyte counts from coexistent infections may have a worse prognosis. Although a conclusive effective therapy does not exist, parathyroidectomy can be safely performed and may benefit some patients with what is often an otherwise fatal disease. The literature to date generally confirms our findings. Key Words: Calciphylaxis, parathyroid hormone, parathyroidectomy, skin necrosis, chronic renal failure.     

Timing of Endoscopic Sinus Surgery in Children: Is There an Impact on Outcome?

OBJECTIVES/HYPOTHESIS: Endoscopic sinus surgery in children continues to be a controversial issue. Major factors in determining when to operate are the duration of the disease and duration of medical treatment. STUDY DESIGN: Prospective study of children referred to a tertiary center. PATIENTS AND METHODS: Eighty-three patients underwent endoscopic sinus surgery for refractory chronic sinusitis. All patients were followed prospectively to evaluate their response to surgery for a mean follow-up period of at least 1 year. A chi2 analysis and logistic regression analysis were performed to determine statistical difference between duration of symptoms and outcome. RESULTS: The overall success rate of endoscopic sinus surgery was 80%. Children who had surgery between 6 and 12 months of symptoms despite continued medical therapy had an 84% success rate, those who had surgery between 12 and 18 months had a 74% success rate, and those with more than 18 months of treatment for symptoms had an 81% success rate (P > .05). CONCLUSIONS: Duration of the symptoms of chronic sinusitis in children of more than 6 months was not a predictor of success of endoscopic sinus surgery in these children. Although there seemed to be a trend toward having a more successful procedure in children who had surgery between 6 and 12 months of medical treatment versus those who had surgery after more than 12 months of medical treatment, this did not reach statistical significance. A prospective study with more patients may shed more light on this subject.     

Biological dental implant: myth or reality?

The currently available options for tooth-loss are prostheses, implants, or surgery (auto-transplantation). They all have their limitations. The emergence of tissue engineering, 15 years ago, was made possible by a better knowledge of the various stages of dental development, and the mastery of stem cell differentiation. It opened a new alternative approach for tooth regeneration. Even if animal experiments have demonstrated that it was possible to obtain a biological tooth from stem cells, two major issues remain to be discussed. Is it possible to use induced pluripotent stem cells instead of embryonic stem cells, which raise an ethical problem? Is it possible to reproduce a dental crown with an adapted shape and colour? Or should we consider the simpler creation of a biological root secondarily covered by a ceramic prosthesis? Our study mentions the main landmarks and the key cells involved in the embryological development of the tooth, establishes a mapping and a list of the various types of stem cells. It details the various methods used to create a biological implant.     

Endoscopic photography: digital or 35 mm?

OBJECTIVE: To compare off-the-shelf digital imaging equipment with a standard single lens reflex 35-mm endoscopic camera in a busy pediatric ears, nose, and throat setting. DESIGN: Two digital cameras with an endoscope adapter and a step-down ring were evaluated to obtain optimal settings for digital endoscopic photography. The equipment was used in various clinical and surgical settings to include otoscopy, sinonasal endoscopy, laryngoscopy, and bronchoscopy. The overall quality, color, brightness, and diagnostic quality of the endoscopic digital photographs were compared with those of the single-lens reflex 35-mm flash-generated photographs by experienced endoscopists. Cost analysis and ease of use were also compared.Subjects Initial digital endoscopic settings were formulated from cadaveric tests. These settings were then studied in multiple patients during endoscopy. RESULTS: Endoscopic digital photography resulted in high-quality images in all settings. Digital images were comparable to 35-mm images. The digital system was easier to use and less expensive than the 35-mm system. CONCLUSIONS: We introduce a simple, inexpensive, and easily available endoscopic digital photography system. Digital photography offers numerous advantages over analog photography in a clinical practice. Digital imaging and archiving is more durable and easier to incorporate into patient records and clinical presentations. As the demand for high-quality digital imaging increases, easy-to-use inexpensive digital endoscopic photography will soon replace 35-mm camera technology.     

Does microscopic experience influence learning curve in endoscopic ear surgery? A multicentric study

ObjectiveThe aim of the present study was to illustrate the learning curve of endoscopic type-1 tympanoplasty comparing experts in microscopic otology versus neophyte surgeons.MethodsEight ear surgeons, from tertiary referral centers, who had performed at least 30 endoscopic type 1 tympanoplasties were included in the study. Demographic data and medical records regarding the first 30 endoscopic type-1 tympanoplasties were retrospectively collected by each surgeon. A 14-questions survey focused on subjective aspects of the learning curve was administered. Surgeons were divided in two groups: one with previous experience in microscopic ear surgery (group 1) and one with no previous experience in ear surgery (group 2). The learning curve of endoscopic type 1 tympanoplasty was compared between the groups.ResultsMean surgical time was 89.2 min in group 1 vs. 79.5 min in group 2 (p < 0.01). When divided in 5 surgeries-steps, the only significant difference was appreciated in the first 5 surgeries with a longer mean time in group 1 vs. group 2 (+28.4 min; p < 0.05).ConclusionsSurgeon's previous experience may influence the EES learning curve. Our results show that the first 5 surgical procedures are more challenging for surgeons experienced in microscopic surgery, subsequently the curve progression improves sharply and appears reversing the initial trend by the end of the 30 surgeries.     

Is stuttering a functional dystonia?

For some years the dystonias have been the subject of major studies and, as far as the generalised dystonias are concerned, of major therapeutic advances. The opposite is true of the so-called focal or functional dystonias, which include conditions such as Meige's syndrome, spasmodic torticollis, writer's cramp, dystonias using instruments especially in musicians, and spasmodic dysphonia. For the last group, the term functional dysphonia would seems to us to be more appropriate. It would appear that what is involved is a disorder not of a muscle group, but rather of a function. Consequently stuttering can, in our opinion, be legitimately considered as a dystonia affecting the articulation of speech, within the global context of a new neurological grouping which could be called 'dysfunctional neurology'.     

Pediatric Endoscopic Dacryocystorhinostomy Failures: Who and Why?

OBJECTIVE: The objectives of this study are to report outcomes of pediatric patients with nasolacrimal duct obstruction (NLDO) who underwent primary endoscopic dacryocystorhinostomy (DCR) and discuss causes of failure. STUDY DESIGN: The authors conducted a retrospective case series. METHODS: Charts of all patients less than 16 years of age who underwent primary endoscopic DCR from 1997 to 2004 were reviewed. Patients were grouped based on the presence or absence of facial anomalies or syndromes and whether the NLDO was congenital or acquired. Success was defined as complete resolution of symptoms, improvement included anatomic patency or partial symptoms, and failure as no improvement or demonstration of patency. RESULTS: Thirty-four patients (43 ducts) aged 11 months to 14 years were identified. There were 17 males and 17 females. Follow up ranged from 2 to 54 months (average, 21 months). Twenty-four patients (29 ducts) had congenital NLDO, seven patients (11 ducts) had congenital syndromes associated with craniofacial abnormalities, and three patients (three ducts) had acquired NLDO. In patients with congenital NLDO without craniofacial abnormalities or syndromes, 22 of 29 eyes (76%) were cured with another three (10%) showing improvement. Only one of 11 (9%) eyes of patients with congenital craniofacial abnormality or syndrome experienced complete resolution and only four of 11 (36%) eyes showed improvement. Of the patients with acquired NLDO, two of three (67%) of the eyes were cured and one (33%) improved. CONCLUSIONS: Endoscopic DCR is safe and effective for most children, although patients with craniofacial abnormalities or syndromes are extremely difficult to cure.
