BACKGROUND: Many studies have looked at the effect of functional endoscopic sinus surgeries (FESS) on nasalance, nasal consonant and nasalized vowels. Only two studies investigated the effect of FESS on vocal sound quality and have not found statistically significant changes before and after operations. The aim of this study was to examine the short-term and long-term objective and subjective changes in the vocal quality of patients after FESS, comparing patients with and without nasal polyps.

METHODS: Sixteen patients were recruited for voice analysis during pre-operative, within two weeks and at least three months post-operatively. Subjective questionnaire was used to assess perception of voice changes.

RESULTS: There were no statistically significant changes in the acoustic parameters of patients with nasal polyposis. In patients with CRS without polyps, there was a statistically significant increase in fundamental frequency (F0) in nasal sound during early follow up. The changes in soft phonation index (SPI) values between the two groups were statistically significant during early follow-ups. Only patients with nasal polyposis perceived a subjective change in their voice post-operatively.

CONCLUSIONS: Clinicians should inform all patients, especially voice professionals about the possible effects of endoscopic sinus surgeries on their voice quality.

Novel use of a Leyla-Yasargil retractor as an endoscope holder during endoscopic sinus surgery

The authors describe a novel way of fashioning an endoscope holder from a common retractor and an ear speculum. Using such a device during endoscopic sinus surgery leaves both of the surgeon's hands free to manipulate the instruments.

Fulltext A new radiological classification for the risk assessment of anterior skull base injury in endoscopic sinus surgery

Keros and Gera classifications are widely used to assess the risk of skull base injury during endoscopic sinus surgery. Although, both classifications are useful preoperatively to stratify risk of patients going for surgery, it is not practical to measure the respective lengths during surgery. In this study, we aimed to propose a new radiological classification (Thailand-Malaysia-Singapore (TMS)) to assess the anatomical risk of anterior skull base injury using the orbital floor (OF) as a reference. A total of 150 computed tomography images of paranasal sinuses (300 sides) were reviewed. The TMS classification was categorized into 3 types by measuring OF to cribriform plate and OF to ethmoid roof. Most patients were classified as TMS type 1, Keros type 2 and Gera class II, followed by patients classified as TMS type 3, Keros type 1 and Gera class 1. TMS has significant correlation with Keros classification (p

Five cases of iatrogenic cerebrospinal fluid (CSF) rhinorrhoea: Early management is crucial

Endoscopic sinus surgery (ESS) is a standard treatment for rhinosinusitis, which failed optimum medical therapy. Iatrogenic cerebrospinal fluid (CSF) rhinorrhoea can occur during ESS warrants early repair of the leakage. The common sites for CSF leakage are cribriform plate, fovea ethmoidalis, and anterior ethmoid sinuses. We present five cases of iatrogenic CSF rhinorrhoea due to ESS and its management.

The creation and verification of cranial models using three-dimensional rapid prototyping technology in field of transnasal sphenoid endoscopy

Surgical navigation systems have been used increasingly in guiding complex ear, nose, and throat surgery. Although these are helpful, they are only beneficial intraoperatively; thus, the novice surgeon will not have the preoperative training or exposure that can be vital in complex procedures. In addition, there is a lack of reliable models to give surgeons hands-on training in performing such procedures.

INTRODUCTION: Endoscopic sinus surgery (ESS) is the mainstay for treatment of chronic rhinosinusitis versus maximal medical therapy. We propose a more economical option, by using steroid-impregnated Gelfoam instead of Nasopore post ESS, as it is less expensive and has showed effectiveness in preventing post-operative bleeding.

MATERIALS AND METHODS: A randomised, double-blinded, placebo-controlled trial was carried out in eight patients with chronic rhinosinusitis or nasal polyposis who were planned for bilateral endoscopic sinus surgery. A Peri-operative Sinus Endoscopy (POSE) Score and Lund-Kennedy Endoscopic Score (LKES) were recorded. The use of hydrocortisone-impregnated Gelfoam dressing versus normal saline-impregnated Gelfoam dressing were compared. Scores were repeated post-operatively at one week, three weeks and three months interval.

RESULTS: For LKES, at the end of three months, 50% of the patients had the same score difference, 37.5% had better results on the study side while 12.5% had better results on the control side. Meanwhile, for POSE Score, at the end of three months, 75% of the patients had better score difference on the study side while 12.5% had better results on the control side.

CONCLUSION: Gelfoam can be used as nasal packing material to deliver topical steroid after endoscopic sinus surgery. Steroid-impregnated nasal dressing after endoscopic sinus surgery may not provide better long-term outcome.
