  • Modified anterior palatoplasty and double suspension sutures (with or without tonsillectomy) in selected patients with obstructive sleep apnea: a preliminary report
    Sleep and Breathing, 2018
    Co-Authors: Sherif M. Askar, Mohammad W. El-anwar, Ali Awad
    Abstract:

    Background Retropalatal region might be considered the most common site of obstruction in patients with snoring and OSA. We aimed at presentation of two combined techniques: modified anterior palatoplasty (MAP) and bilateral double suspension suture (DSS). Methods This prospective study was conducted on OSA patients with retro-palatal collapse only that was confirmed by Nasoendoscopy during Muller’s maneuver and drug induced sleep endoscopy. MAP and DSS were performed for all patients. Preoperative and 6 months after surgery, all patients underwent fiber-optic Nasoendoscopy using the Muller maneuver and polysomnography, snoring scores, and Epworth Sleepiness Scale (ESS) values were assessed. Results Mean apnea hypopnea index (AHI) dropped significantly ( p  

  • Hyoid Bone Suspension as a Part of Multilevel Surgery for Obstructive Sleep Apnea Syndrome
    International Archives of Otorhinolaryngology, 2017
    Co-Authors: Abd Alzaher Tantawy, Sherif M. Askar, Ali Awad, Hazem Saeed Amer, Mohammad Waheed El-anwar
    Abstract:

    Introduction  Since oropharyngeal surgery alone is often insufficient to treat obstructive sleep apnea (OSA), advances have been developed in hypopharyngeal surgery. Objective  To assess hyoid suspension surgery as part of a multilevel OSA surgery, also including palatal surgery. Methods  The study included patients with OSA symptoms with apnea hypopnea index (AHI) > 15. They were scheduled for hyoid suspension after a Nasoendoscopy during Muller maneuver and drug induced sleep endoscopy (DISE). All patients had body mass index (BMI)  Results  The mean AHI dropped significantly ( p 2 ) saturation level increased significantly from 66.8 ± 11.3 to 83.2 ± 2.86 ( p p p Conclusion  Hyoidothyroidopexy using absorbable suture seems to produce a good outcome in treating OSA. It could be effectively and safely combined with other palatal procedures in the multilevel surgery for OSA.

  • A speech Nasoendoscopy-based surgeon’s decision for correction of velopharyngeal insufficiency following adenotonsillectomy
    European Archives of Oto-Rhino-Laryngology, 2014
    Co-Authors: Sherif M. Askar, Tamer S. Abou-elsaad
    Abstract:

    Both sphincter pharyngoplasty (SP) and pharyngeal flap (PF) procedures have gained popularity among surgeons as effective surgical management for velopharyngeal insufficiency (VPI). Different centers prefer either SP or PF and have published their results to support this preference. But is one technique superior to the other? To answer this question, we have adopted the concept of differential therapeutic management, based on detailed assessment of velopharyngeal function. According to this assessment either SP or PF was performed for management of VPI (secondary to adenotonsillectomy). The aim of this work is to evaluate and compare the surgical results after SP and PF (based on the preoperative Nasoendoscopy and phoniatrics’ evaluation). This study was conducted on 31 patients with persistent hypernasality after adenotonsillectomy. All patients were subjected to perceptual speech evaluation and nasoendoscopic examination. According to this evaluation and data analysis, 18 patients were operated by SP and 13 patients underwent PF. Statistically, highly significant improvements were found when comparing pre- versus postoperative perceptual speech evaluation following both SP and PF ( P   0.05). Preoperative differential diagnosis of VPI using perceptual speech assessment and Nasoendoscopy of the velopharynx allows for tailored surgical management with either SP or PF. Both SP and PF procedures could yield good surgical outcomes, when patients are properly selected and the technique is chosen according to preoperative assessment.

  • Endoscopic-assisted sphincter pharyngoplasty (EASP)
    International Journal of Pediatric Otorhinolaryngology, 2012
    Co-Authors: Sherif M. Askar
    Abstract:

    Abstract Objectives Sphincter pharyngoplasty operation was designed for the treatment of velopharyngeal insufficiency via a transoral route. Few investigators used palatal stretching sutures or palatal splitting procedures (which may affect the performance of the palate) to overcome the problem of difficult visualization. The purpose of this study is to present and evaluate the role of intraoperative Nasoendoscopy during sphincter pharyngoplasty. Although Vadodaria et al. (2004) (in a cadaver study) used the endoscope to perform SP operation, this study (to our knowledge) is the first report of intraoperative Nasoendoscopy in sphincter pharyngoplasty. Subjects and methods This prospective study was conducted at ORL-HN Department, Zagazig University Hospitals, Zagazig University, Egypt. Seven patients with persistent postoperative hypernasality were enrolled in this work. They were prepared by head and neck physical examination and phonetic evaluation. Patients were subjected to treatment by endoscopic-assisted sphincter pharyngoplasty, a procedure that was designed to combine both a transoral and a transnasal routes via the aid of nasoendoscope. Postoperative nasoendoscopic and phonetic assessment was done for all of the patients. Results The procedure is easily conducted, done by available instruments with no extra burden over patients or hospitals. The procedure insured an under vision and well controlled steps. No major complications were recorded. Good speech outcome results were reported. Conclusion Endoscopic-assisted sphincter pharyngoplasty is a new role the Nasoendoscopy can play. The study demonstrates the feasibility of endoscopic assistance in sphincter pharyngoplasty, with the advantage of improved visualization of a traditionally difficult-to-expose area. There was neither increased risk to the patients nor added cost to the procedure since only widely-available instrumentation was used. The technique lessened the need for palatal stretching or splitting during the procedure.

  • diagnosis and treatment of isolated benign sphenoid sinus disease under Nasoendoscopy
    Sichuan Medical Journal, 2008
    Co-Authors: Liu Dingron
    Abstract:

    Objective To improve the diagnosis and treatment of isolated sphenoid benign disease.Methods The clinical data of 24 cases suffering from isolated sphenoid benign disease first manifesting headache and/or eye symptoms from October 1998 to July 2006 were analyzed retrospectively.All of patients underwent endoscopic sphenoid surgery.Results Among these cases,6 were with cyst in sphenoid sinus,18 were fungus sphenoiditis.All these cases manifested themselves mainly as headache,sneezing with blood and ocular symptoms,like blepharoptosis,diplopia and-visual deteroration.The symptoms of all patients were improved or disappeared after operations.Conclusion Isolated sphenoid benign disease easily misdiagnosed and missed diagnosis,CT and MRI was one of the most valuable examination for this disease.Endoscopic sinus surgery was the first choice of treatment for isolated sphenoid benign disease.
