  • transantral balloon dilation plus posterior Ethmoidectomy
    Laryngoscope, 2011
    Co-Authors: Victor Kizhner, Michael Setzen, Yosef P Krespi
    Abstract:

    Objectives/Hypothesis: Transantral endoscopic balloon dilatation (TABD) was recently introduced for the management of limited mild maxillary and ethmoid disease. An expanded approach by inserting surgical tools into the antrum via a second port, directed toward the maxillary ostium, ethmoid infundibulum, and posterior ethmoids will allow for the treatment of moderate disease as well. Study Design: Retrospective data review. Methods: A study including all TABD procedures performed between January and December 2009 was performed. Sublabial approach with two working channels, one for the endoscope and a second port for balloon dilatation or other surgical instrumentation, was devised. Both channels were created via mini-trephine aimed toward the osteo-meatal complex (OMC) with different angulations. The same approach was used for transantral posterior Ethmoidectomy (TAPE). Data collected included demographics, Sino-Nasal Outcome Test (SNOT) scores, Lund-Mackay score, and complications. Results: Thirty-five patients with 64 dilated sinuses and 10 TAPE procedures were enrolled. All SNOT scores showed statistically significant improvement decreasing from 1.77 to 0.83. Complication rate was minimal. Only a small number of procedures were converted to standard endoscopic septoplasty (ESS) owing to severity of OMC disease. TAPE proved to be a minimally invasive procedure. Conclusions: Two trocars inserted through the canine fossa can achieve a successful result in moderate antral disease for TABD and allow TAPE to be performed, thus creating a bridge between mild disease and one requiring standard full ESS. The minimally invasive approach proved to be particularly useful.

  • an anatomic approach to endoscopic intranasal Ethmoidectomy
    Laryngoscope, 1998
    Co-Authors: Steven D Schaefer
    Abstract:

    Objectives: To develop an anatomic and functionally based approach to endoscopic intranasal Ethmoidectomy. To develop such an approach using the salient features of the anterior to posterior (AP) and posterior to anterior (PA) intranasal sinus operations. To assess the safety of this form of Ethmoidectomy in a patient population. Study Design: Retrospective chart review of patients undergoing Ethmoidectomy by author or by residents under his direct supervision. Setting : University teaching hospital. In the 509 patients meeting study criteria, 168 anterior ethmoidectomies, 586 total ethmoidectomies, 264 sphenoidotomies, 290 frontal sinusotomies, and 838 antrostomies were performed between April 1992 and August 1997. Results: A complication rate of 0.98% and revision rate 2.9% were observed. Conclusions: Combining an AP approach to conserve sinus anatomy with a PA approach to avoid surgery directed toward the skull base provides a functional and safe procedure as demonstrated by the reported results.

  • outcomes of chronic frontal sinusitis treated with Ethmoidectomy a prospective study
    International Forum of Allergy & Rhinology, 2016
    Co-Authors: Waleed M Abuzeid, Timothy L Smith, Jess C Mace, Milena L Costa, Luke Rudmik, Zachary M Soler, Grace S Kim, Peter H Hwang
    Abstract:

    Background In medically refractory chronic frontal sinusitis, Ethmoidectomy without instrumentation of the frontal ostium may resolve frontal disease. Our aim was to determine the efficacy of Ethmoidectomy alone for the treatment of chronic frontal sinusitis. Methods Adults with chronic rhinosinusitis prospectively enrolled in a multicenter study who demonstrated frontal sinusitis on computed tomography were divided into 2 groups: (1) endoscopic sinus surgery (ESS) incorporating Ethmoidectomy, but excluding frontal sinusotomy; and (2) ESS incorporating frontal sinusotomy. The primary outcome was improvement in 22-item Sino-Nasal Outcome Test (SNOT-22) scores. Secondary outcomes included endoscopic scores and use of corticosteroids and antibiotics. Results A total of 196 cases undergoing frontal sinusotomy and 30 cases treated with Ethmoidectomy without frontal sinusotomy were analyzed and were comparable demographically. The prevalence of nasal polyps, previous ESS, asthma, and aspirin intolerance was more common in the frontal sinusotomy group (p < 0.050). Preoperative endoscopy and computed tomography scores were higher in the frontal sinusotomy group (p ≤ 0.001). Postoperatively, both groups showed comparable SNOT-22 scores with worse endoscopy scores in the frontal sinusotomy group (p = 0.038). Postoperative improvement in SNOT-22 total and subdomain scores was comparable between groups. Nasal endoscopy scores improved to a greater degree in the frontal sinusotomy group (p = 0.023). Duration of postoperative topical steroid use was higher in the frontal sinusotomy group (p = 0.007). Revision surgery was needed in 2.6% of frontal sinusotomy patients and 0% of patients without frontal sinusotomy. Conclusion The treatment of chronic frontal sinusitis through Ethmoidectomy is a potential alternative to frontal sinusotomy achieving similar quality of life (QOL) improvements in patients manifesting less severe sinus disease.

  • middle turbinate stabilization technique in endoscopic sinus surgery
    Archives of Otolaryngology-head & Neck Surgery, 1996
    Co-Authors: Robert S Thornton
    Abstract:

    Background: Lateralization of the middle turbinate with scarring and obstruction of the middle meatus after endoscopic Ethmoidectomy has accounted for a high percentage of postoperative complications. Objective: To evaluate a suture stabilization technique of the middle turbinates in an attempt to solve this problem and preserve the middle turbinate. Design: Retrospective chart review of 31 consecutive patients undergoing endoscopic sinus surgery with suture stabilization of the middle turbinate. Results: With the technique of suture stabilization of the middle turbinate in 60 operated-on sides of 31 patients, 59 sides showed the middle meatus to be patent without synechia or maxillary sinus ostium obstruction postoperatively. Conclusion: The complication of lateralization of the middle turbinate with scarring and obstruction of the middle meatus after endoscopic Ethmoidectomy can be prevented with suture stabilization of the middle turbinate, and the middle turbinate can be preserved.
