A profound case of neurally mediated syncope with asystole after septoplasty.

J Clin Anesth 2012 Jun;24(4):310-4

Department of Otolaryngology - Head and Neck Surgery, Tripler Army Medical Center, TAMC, HI 96859, USA.

Vasovagal syncope (VVS) is an alarming yet benign condition that may present postoperatively for the first time in otherwise healthy patients. Although VVS is associated anecdotally with nasal manipulation, no data have been found to quantify this incidence with otolaryngology surgeries. We present a case of profound, recurrent syncope and documented asystole with an initial diagnosis of glossopharyngeal neuralgia. We conclude with a discussion of neurally mediated syncope particular to the perioperative setting. It is essential to recognize neurocardiogenic etiology to differentiate it from other more concerning causes of syncope and asystole.

Facial Nerve Grading System 2.0.

Otolaryngol Head Neck Surg 2009 Apr;140(4):445-50

Bobby R Alford Department of Otolaryngology, Head and Neck Surgery, Baylor College of Medicine, Houston, TX 77030, USA.

Objective: To present an updated version of the original Facial Nerve Grading Scale (FNGS), commonly referred to as the House-Brackmann scale.

Study Design: Controlled trial of grading systems using a series of 21 videos of individuals with varying degrees of facial paralysis.

Results: The intraobserver and interobserver agreement was high among the original and revised scales. Nominal improvement is seen in percentage of exact agreement of grade and reduction of instances of examiners differing by more then one grade when using FNGS 2.0. FNGS 2.0 also offers improved agreement in differentiating between grades 3 and 4.

Conclusion: FNGS 2.0 incorporates regional scoring of facial movement, providing additional information while maintaining agreement comparable to the original scale. Ambiguities regarding use of the grading scale are addressed.

Carcinoid tumor of the middle ear: clinical features, recurrences, and metastases.

Laryngoscope 2005 Sep;115(9):1660-6

Division of Otolaryngology, Tripler Army Medical Center, Honolulu, HI, USA.

Objective: Present four new cases of carcinoid tumor of the middle ear, two of which developed late recurrences and regional metastases. Review the literature to identify the clinical features, rate of recurrence, and incidence of metastasis of carcinoid tumor of the middle ear.

Study Design: Retrospective chart review.

Setting: Tertiary referral hospital.

Patients: Eligibility criteria consist of a diagnosis of carcinoid tumor of middle ear.

Intervention: Surgical excision of primary and metastatic disease.

Main Outcome Measure: Clinical characteristics, rate of recurrence, and incidence of metastasis of carcinoid tumor of the middle ear.

Results: Forty-six patients with carcinoid tumor of the middle ear are included in this report, 42 patients were identified from a review of the literature, and 4 new patients are presented. The most common presenting symptom was hearing loss. Surgical excision was the treatment with radical mastoidectomy being the most common procedure. Ten (22%) patients developed locally recurrent disease, and four (9%) developed regional metastases.

Conclusions: Carcinoid tumor of the middle ear is an infrequent cause of a middle ear mass, with only 46 cases published. Despite previous assertions of benignancy, the findings of this study suggest that carcinoid tumor of the middle ear is indeed a potential low-grade malignancy with documented metastatic potential. Almost all middle ear adenomatous tumors ("adenoma" and "carcinoid") show evidence of neuroendocrine differentiation, and so at least some middle ear carcinoids ("adenomas") appear to represent well-differentiated neuroendocrine carcinomas. Presentation and symptoms are consistent with a middle ear mass and rarely include carcinoid syndrome. Surgical treatment is recommended and tailored to the extent of disease. Patients with carcinoid tumor of the middle ear require indefinite follow-up for possible recurrence or metastasis.

Postauricular periosteal-pericranial flap for mastoid obliteration and canal wall down tympanomastoidectomy.

Otol Neurotol 2004 Nov;25(6):873-8

Department of Otolaryngology, Massachusetts Eye and Ear Infirmary, Harvard Medical School, Boston, Massachusetts 02114, USA.

Objective: To describe an effective technique for mastoid cavity obliteration in canal wall down tympanomastoidectomy for chronic otitis media and review its efficacy in producing a dry, low-maintenance, small mastoid cavity.

Design: : Retrospective clinical study of a consecutive series of procedures from 1995 to 2000.

Setting: Tertiary referral center and institutional academic practice in otology and neurotology.

Patients: Sixty consecutive procedures for active chronic otitis media with a minimum follow-up of 12 months (mean, 31 mo; range, 12-80 mo).

Intervention: All patients had canal wall down mastoidectomy with simultaneous tympanoplasty including split-thickness skin grafting. An inferiorly pedicled, periosteal-pericranial flap was used in conjunction with autologous bone pate to obliterate the mastoid cavity. The additional length provided by the pericranial extension of the flap permitted it to reach superior to the lateral canal and into the sinodural angle, with improved coverage of bone pate and better reduction of cavity size.

Outcome Measures: The primary outcome measure was control of suppuration and creation of a dry, low-maintenance mastoid cavity, which was assessed using a previously developed semiquantitative scale. This scale includes a temporal dimension to assess control of infection. Secondary outcome measures included postoperative complications (i.e., hematoma, infection, flap necrosis, and meatal stenosis) and incidence of recurrent or residual cholesteatoma.

Results: Forty-nine ears (82%) maintained a small, dry, healthy mastoid cavity. Five ears (8%) had intermittent otorrhea easily controlled by topical treatment. Six ears (10%) had suboptimal control of otorrhea, of which four had meatal stenosis. There were no residual or recurrent cholesteatomas. Outcomes remained stable over progressively longer follow-up, up to 80 months.

Conclusion: Obliteration of a canal wall down mastoid cavity by a postauricular periosteal-pericranial flap with autologous bone pate is a reliable and effective technique that results in a dry, trouble-free mastoid cavity in 90% of patients with active chronic otitis media.

Superior semicircular canal dehiscence presenting as conductive hearing loss without vertigo.

Otol Neurotol 2004 Mar;25(2):121-9

Department of Otology and Laryngology, Harvard Medical School, and the Department of Otolaryngology, Massachusetts Eye and Ear Infirmary, Boston, Massachusetts 02114, USA.

Objective: The objective of this study was to describe superior semicircular canal dehiscence (SSCD) presenting as otherwise unexplained conductive hearing loss without vestibular symptoms.

Study Design: Retrospective.

Setting: Tertiary referral center.

Patients: The study comprised 8 patients (10 ears), 5 males and 5 females aged 27 to 59 years. All 10 ears had SSCD on high-resolution computed tomography scan of the temporal bone. DIAGNOSTIC TESTS AND RESULTS: All 10 ears had significant conductive hearing loss. The air-bone gaps were largest in the lower frequencies at 250, 500, and 1000 Hz; the mean gaps for these 3 frequencies for the 10 ears were 49, 37, and 35 dB, respectively. Bone-conduction thresholds below 2000 Hz were negative (-5 dB to -15 dB) at one or more frequencies in 8 of the 10 ears. There were no middle ear abnormalities to explain the air-bone gaps in these 10 ears. Computed tomography scan and laboratory testing indicated lack of middle ear pathology; acoustic reflexes were present, vestibular evoked myogenic potentials (VEMPs) were present with abnormally low thresholds, and umbo velocity measured by laser Doppler vibrometry was above mean normal. Middle ear exploration was negative in six ears; of these six, stapedectomy had been performed in three ears and ossiculoplasty in two ears, but the air-bone gap was unchanged postoperatively. The data are consistent with the hypothesis that the SSCD introduced a third mobile window into the inner ear, which in turn produced the conductive hearing loss by 1) shunting air-conducted sound away from the cochlea, thus elevating air-conduction thresholds; and 2) increasing the difference in impedance between the oval and round windows, thus improving thresholds for bone-conducted sound.

Conclusion: SSCD can present with a conductive hearing loss that mimics otosclerosis and could explain some cases of persistent conductive hearing loss after uneventful stapedectomy. Audiometric testing with attention to absolute bone-conduction thresholds, acoustic reflex testing, VEMP testing, laser vibrometry of the umbo, and computed tomograph scanning can help to identify patients with SSCD presenting with conductive hearing loss without vertigo.

Superior semicircular canal dehiscence syndrome. Case report.

J Neurosurg 2004 Jan;100(1):123-4

Department of Otolaryngology, Massachusetts Eye and Ear Infirmary, Boston, Massachusetts 02114, USA.

The authors present the case of a man who had superior semicircular canal dehiscence syndrome in addition to chronic otitis media. This case is atypical because the patient coincidentally had middle ear and mastoid disease, which previously had been treated surgically. The prior ear surgery delayed the diagnosis of superior semicircular canal dehiscence syndrome and increased the complexity of the repair of the superior semicircular canal dehiscence. Superior semicircular canal dehiscence syndrome is a recently recognized syndrome resulting in acute or chronic vestibular symptoms. The diagnosis is made using history, vestibular examination, and computerized tomography studies. Neurosurgeons should be aware that patients with superior semicircular canal dehiscence syndrome who experience disabling chronic or acute vestibular symptoms can be treated using a joint neurosurgical-otological procedure through the middle cranial fossa.

Telemedicine: teleproctored endoscopic sinus surgery.

Laryngoscope 2002 Feb;112(2):216-9

Department of Surgery, Tripler Army Medical Center, Honolulu, Hawaii 96859-1000, USA.

Objective/hypothesis: Teleproctored surgery projects a surgeon's expertise to remote locations. The objective of the present study was to evaluate the safety and feasibility of this technique as compared with the current standard of care.

Study Design: Prospective.

Methods: A study was conducted in a residency training program comparing conventionally proctored endoscopic sinus surgery cases with teleproctored cases, with the faculty surgeon supervising through audiovisual teleconferencing (VTC) in a control room 15 seconds from the operating room.

Results: Forty-two control patients (83 sides) and 45 teleproctored patients (83 sides) were evaluated. There were no internal differences between groups regarding extent of polypoid disease, revision status, procedures per case, degree of difficulty, general or local anesthesia, or microdebrider use. There were no cases of visual disturbance, orbital ecchymosis or hematoma, or cerebrospinal fluid leak. Orbital fat herniation and blood loss were equal between groups. Three teleproctored cases required faculty intervention: two for surgical difficulty, one for VTC problems. Teleproctored cases took 3.87 minutes longer per side (28.54 vs. 24.67 min, P <.024), a 16% increase. This was thought to be a result of nuances of VTC proctoring. Residents had a positive learning experience, with nearly full control of the operating suite combined with remote supervision through telepresence. Faculty thought such supervision was safe but had concerns regarding personal skills maintenance.

Conclusions: Teleproctored endoscopic sinus surgery can be safely performed on selected cases with an acceptable increase in time. Teleproctored surgery with remote sites may continue to be safely investigated. Incorporating remote supervision through telepresence into the curriculum of surgical residency training requires further study.
