"Thai Noodle": A Novel Technique for Post Radiation Choanal Stenosis.

The aim of this retrospective study is to describe a novel endoscopic technique to treat post radiation choanal stenosis. We describe a novel "Thai noodle" silastic splint, which is tailor-made, increases compliance, reduces pain and recurrence. A retrospective study over a period of 2 years was done to evaluate the results of our "Thai noodle" technique, which included 4 patients who had previously been treated with conventional endoscopic release and commercially available nasal airway splint. All patients were followed up for a period of 1 year. All 4 patients, which included 3 females and 1 male, were treated with our novel technique. All the patients remained symptom free and none required further intervention. The Thai noodle technique customises the splint for every patient, which along with an adequately done posterior septectomy increases patient comfort and reduces recurrence which is seen with conventional airway splints.

Septoplasty and Nasal Packs From Otolaryngologists' Perspectives: A Cross-Sectional Survey.

Introduction Septoplasty is a commonly performed surgery by otolaryngologists. This study examines the routine use of non-absorbable nasal packs in the postoperative period in Kuwait. Our aim is to assess the views of otolaryngologists in Kuwait regarding the routine use of non-absorbable nasal packing after septoplasty with or without turbinoplasty. Materials and methods A cross-sectional study, an anonymous survey, consisting of 10 questions, using Google Forms was conducted. It was distributed via WhatsApp and in person hard copies to otolaryngologists - head and neck surgeons in Kuwait. Data were securely stored and analyzed using Stata (StataCorp LLC, College Station, Texas) software. Results Fifty participants have completed the survey. The majority were routinely performing septoplasty for a symptomatic deviated nasal septum (n= 47, 94%). Out of those, 43% (n = 21) usually use silastic splints to prevent postoperative complications, including bleeding, hematoma formation, and adhesions. The use of quilting sutures for the same purpose was done by 21% (n = 10), and 17% (n = 8) used non-absorbable nasal packs. Only two participants believed that no specific intervention was required. More than half used postoperative nasal packs in the case of intra-operative bleeding (n=26, 52%), while 18% (n = 9) believed that it is only necessary in selected cases with predisposing factors to bleeding. Ninety-two percent (n = 46) thought that pain and discomfort were associated with the use of non-absorbable nasal packs, and 50% (n = 25) believed that it could cause hemodynamic instability. Moreover, 66% (n = 33) agreed that quilting or trans-septal sutures can safely substitute nasal packs following septoplasty. Awareness of recent updates on the complications related to nasal packing varied, with more than half of the otolaryngologists being knowledgeable (n = 29, 58%). Discussion Septoplasty, a common surgical intervention for correcting a misaligned nasal septum, addresses various symptoms, such as nasal obstruction, obstructive sleep apnea, epistaxis, and headache. While the practice of nasal packing for 24-48 hours post-septoplasty is widespread, it remains a topic of controversy. Current literature supports the continued use of nasal packing for patients at high risk of bleeding. However, potential drawbacks, including increased pain, headache, and prolonged hospital stay, raise concerns about its overall benefits. An alternative approach, utilizing quilting sutures without nasal packs, has shown promising results in comparative studies, demonstrating less pain and minimal bleeding. Additionally, trans-septal sutures emerge as a safe alternative, minimizing dead space and reducing post-operative complications. Conclusion It appears that otolaryngologists in Kuwait have diverse opinions with regard to nasal packing following septoplasty. Further research is needed to establish evidence-based guidelines for this common procedure.

Submucous resection of the septum versus septoplasty a comparison study

Background: Nasal septal deviation is a common cause for nasal obstruction and usually treated by surgery. Submucous resection of the septum (SMR) and septoplasty are the common procedures for the treatment of nasal septal deflection.Aims of the study: To audit the functional outcome of the patients undergoing submucous resection of the septum and septoplasty for deflected nasal septum.
 Materials and methods: 100 patients are complaining from symptomatic nasal obstruction due to nasal septal deviation. Their ages are ranged from 18-55 years. They were divided in to two groups, 60 of them were treated by SMR and 40 patients (caudal end and anterior deviation) were treated by septoplasty in Alzahra Teaching Hospital, Al- Kut / Iraq. From January 2009 to December 2011. Both surgeries were done under general anaesthesia with anterior nasal packs for 24 hours. For the patients with septoplasty a bilateral silastic splints left for 10 days. Follow up done in the outpatient department for 6 months to 1year.
 Results: The functional nasal obstruction was relieved in 50/60 patients (83.3%) for SMR and 28/40 (70%) for septoplasty. The overall complications were nearly equal (33.3%) for SMR and (30%) for septoplasty.
 Conclusion: The study revealed the superiority of SMR in relieving the symptomatic nasal obstruction than septoplasty.

Assessing effects of modification of middle meatal silastic splint after endoscopic sinus surgery for nasal polyps: A randomized controlled study

PurposeTo investigate the efficacy of middle meatal silastic splint in preventing adhesions after bilateral endoscopic sinus surgery (ESS) for chronic rhinosinusitis with nasal polyps (CRSwNP), and to assess nasal symptoms and endoscopic findings in splinted and non-splinted sides. MethodsAfter completion of ESS, silicon silastic splints were randomly inserted in the middle meatus of one nasal side, while no stent in the other side (control). The surgeon was blinded to the side selection, and splint insertion until removal after 1 week. Patients were followed -up after 1 week, 1 and 6 months. Each side of the nasal cavity was assessed for adhesions, crusting, pus, pain, nasal obstruction, and nasal discharge by endoscopic examination and visual analogue scale. ResultsForty-nine patients (98 nasal sides) were included. At the 1st week visit, there was no significant difference between the splinted and non-splinted sides for all investigated parameters.After 1- month, adhesions were seen in 10% of the splinted sides, while it was in 26% of the non-splinted sides (P = 0.037).At the 6 -month follow-up visit, the adhesions rate remained 10% in the splinted sides, however the rate increased to 32% in the non-splinted sides (P = 0.007). All other examined parameters remained statistically insignificant between both sides throughout the follow -up visits. ConclusionsMiddle meatal silastic splint is significantly reducing middle meatal adhesions with low complication rate in CRSwNP patients undergoing ESS. Our results support its usage when the middle turbinate is unstable or traumatized during surgery.

The Effect of Dexpanthenol-Vitamin A (Nazalnem) on Silastic Splints After Nasal Septal Surgery.

To investigate the effect of dexpanthenol-vitamin A (Nazalnem) ointment applied to the surface of silastic splints with an airway immediately after nasal septal surgery on postoperative complaints and nasal mucosa function. The study enrolled 60 patients undergoing nasal septoplasty surgery. Group 1 (n = 30) received silastic splints with ointment containing dexpanthenol-vitamin A (Nazalnem), and Group 2 (n = 30), the control group, received silastic splints with vaseline. Of these patients, 2 patients from the Group 1 and 9 from the Group 2 were excluded.A thin layer of ointment was applied to the flat side of a silastic splint with an airway. The splints were removed on the second postoperative day. Patients were evaluated preoperatively and 1 and 2 weeks postoperatively using a visual analog scale and the Sino-Nasal Outcome test (SNOT-22). Mucociliary clearance (MCC) tests were performed at the same times. Visual analog scale for nasal crusting, nasal congestion, and foul odor was better in Group 1 than in Group 2 both at 1 week and at 2 weeks postoperatively (P < 0.05).The SNOT scores were significantly lower in Group 1 than in Group 2 at 1 week (P < 0.01), but did not differ at 2 weeks postoperatively (P > 0.05).Postoperatively, the MCC were insignificant between the groups and within the groups at 1 and 2 weeks (P > 0.05). Although Dexpanthenol-Vitamin A ointment had no direct effect on wound healing, it had significant effects on crusting, obstruction, and foul smell. However, silastic splints with dexpanthenol did not improve the MCC of the nose.

Nasal septum configuration as a basis for novel septal splints.

The objective is to use anatomical determinations of nasal septum shape and surface area in adults as a design basis for silastic septal splints of universal size and fit and offering maximum possible surface coverage. The objective is also to devise a method of securing the septal splints, so that surface pressure on septal mucosa is distributed as evenly as possible while not interfering with capillary perfusion. Nasal septum area was determined in 21 Caucasian body donors, and nasal septum thickness was measured in 20 CT scans. Septal splints of universal size and shape were prepared from silastic sheeting. The holding force of various neodymium-iron-boron (NdFeB) magnets, and the surface pressure exerted by magnet-containing septal splints was calculated. These septal splints of novel design offer a satisfactory fit in routine clinical practice. The splints can be securely attached with built-in NdFeB magnets, and surface pressure can be distributed evenly across the nasal septum while not interfering with mucosal tissue perfusion. With their simple intranasal insertion, these magnet-containing septal splints of universal size and optimised shape offer maximum possible septum coverage following septoplasty/septorhinoplasty. The absence of interference with septal tissue perfusion means that they are likely to be associated with fewer postoperative complications and better outcomes.

Evaluation of Silastic Splints following Endoscopic Sinus Surgery

Middle meatal adhesions are considered the most common complication of Functional Endoscopic Sinus Surgery (FESS), ranging in incidence from 1 to 36%. Consequently the recurrence and persistence of symptoms increase, resulting in revision surgery in up to 25% of the cases. Although different methods have been attempted to prevent adhesions, each procedure involves some disadvantages and no standard method has been proposed. This study evaluates the efficacy of a 0.85 mm thick polymeric Silastic splint, in preventing middle meatal synechiae, in postoperative FESS patients. 12% of patients with splint had adhesions while 19.2% of patients without splint had adhesions. Splints do not appear to have a statistically significant advantage in preventing middle meatal synechiae following FESS. However, larger studies are needed to confirm this.

Healing septal perforations by secondary intention using acellular dermis as a bioscaffold.

Several techniques are described in the literature for nasal septal perforation repair. Most of these involve interposition grafts in conjunction with local pedicled mucosal flaps. The following article describes our experience using acellular dermis as a bioscaffold to support the regrowth of nasal septal mucosa by secondary intention. Retrospective chart review of all patients who underwent repair of nasal septal perforations by the senior author using acellular dermis placed between the 2 sides of the perforation and covered with silastic splints to allow for mucosalization. Thirteen patients underwent nasal septal perforation repair using this technique. All perforations repaired were under 2 cm in greatest dimension. Two-thirds of patients had complete closure of the perforation upon initial use of bioscaffolding technique. The remaining third achieved near-total closure with bioscaffolding technique and were able to be completely closed with a single additional procedure. Acellular dermis offers an alternative to most currently described complex flaps. The method can be used in patients with defects less than 2 cm, but initial data suggest caution when using in those with wound healing impediments. This technique is also an excellent choice for patients with multiple small septal perforations.

Evaluation of domestic and Yucatan swine nasal sinus anatomy as models for future sinonasal research of medications delivered by standard instruments used in functional endoscopic sinus surgery

There is a need to find an animal model to study new medications to improve mucosal wound healing after functional endoscopic sinus surgery (FESS). Current literature suggests swine as a potential candidate. The lack of information correlating swine computer tomography (CT) and endoscopic sinonasal anatomy prompted us to investigate them in the domestic and Yucatan swine to determine their feasibility as models to test new medications and drug-embedded stents applied using FESS techniques. Two domestic pig heads and 2 Yucatan pig heads were imaged using helical thin slice (1 mm) CT. Two rhinologists analyzed the images and performed endoscopy on the swine. Particular attention was given to accessing the frontal sinus and suturing stents to the nasal septum using standard endoscopic instruments. CT confirmed that swine sinonasal anatomy is largely similar to human, with all major sinuses present. The middle and inferior turbinates of swine arise from a single uniturbinate. The superior turbinates contain large concha bullosa. Unlike human, swine nasal septum is bone anteriorly and cartilage posteriorly. The frontal sinus ostia, regardless of head size, were consistently around 10 cm from the nasal aperture. On endoscopy, domestic swine frontal sinus ostia were easily accessible for topical medication deposition. Silastic splints can be sutured to the domestic swine septum through the posterior cartilaginous portion, allowing for studies involving medication-eluting material. The narrower nasal cavity of Yucatan pigs prohibited endoscopic maneuvers. Domestic swine, but not Yucatan, are a feasible model for future sinonasal research using standard FESS instruments.

Silastic Splints Reduce Middle Meatal Adhesions after Endoscopic Sinus Surgery

Adhesions frequently form between the middle turbinate and lateral nasal wall after endoscopic sinus surgery (ESS) and are a possible cause for surgical failure. Many absorbable and nonabsorbable spacers have been tried to improve healing. This study was designed to ascertain whether placement of a thin silastic splint into the middle meatus after sinus surgery for 2 weeks reduces adhesion formation and whether a reduction in the adhesion rate improves patient outcomes in the early postoperative phase. Forty-two patients who were scheduled to undergo ESS for chronic rhinosinusitis were randomized to have a silastic splint placed into the middle meatus on one side of the nose but not the other at the completion of surgery. Splints were removed 2 weeks postoperatively. Symptom scores were recorded for each side of the nose up to 12 weeks after surgery and ethmoid cavities were graded at the 6- and 12-week visits along with assessment of adhesions. Patients were blinded to which side was splinted as was the surgeon assessing ethmoid cavities at 6 and 12 weeks. Thirty-three patients completed 12 weeks of follow-up. Nasal obstruction and facial pain/discomfort were significantly higher on splinted sides for the first 2 weeks. More interventions were performed to debride adhesions in nonsplinted sides. Endoscopy revealed no adhesions at 12 weeks for sides treated with a splint whereas 9 of 33 nonsplinted sides had persistent adhesions. There were no significant differences in symptom or ethmoid cavity scores at 6 or 12 weeks between sides treated with splints versus sides treated without splints or between sides with adhesions versus without adhesions. Middle meatal silastic splints reduce adhesions after ESS but increase early nasal obstruction and discomfort. Their use did not significantly change symptom or ethmoid cavity scores at 12 weeks.

Objective Usefulness of Thin Silastic Septal Splints after Septal Surgery

Silastic splints have been used as effective tools for septal support, avoiding adhesion, and mucosal healing after septal surgery. Furthermore, although many surgeons insert septal splints, no well-designed trials exist to support their use. A randomized double-blinded controlled trial was performed. We recruited 40 subjects who had undergone septoplasty only without sinus surgery or turbinoplasty. A silastic septal splint was inserted in one side of the nasal cavity at the end of each septoplasty, with the other side serving as a control. The splint side and control side were randomly selected. Nasal discomfort score (10-point scale) and mucosal status (grades 1-4) were surveyed in a blinded setting on postoperative days 7 and 14. Forty of 83 subjects fulfilled the enrollment criteria. On the 7th postoperative day there was no significant difference in nasal discomfort between the splint and control sides (6.2 ± 1.28 and 5.7 ± 1.27, respectively; p = 0.116), but the mucosal status was better on the splint side than on the control side (1.5 ± 0.51 and 2.5 ± 0.85; p < 0.001). At 14 days postoperatively, the symptom score (2.7 ± 1.06 versus 3.8 ± 1.25; p < 0.001) and mucosal status (1.5 ± 0.55 versus 1.9 ± 0.68; p = 0.013) were significantly better on the splint side compared with the control side. Insertion of a silastic septal splint after septal surgery should be accepted as a routine procedure.

Diagnosis and management of nasal fractures

The nasal bony–cartilaginous framework provides support to the nose and maintains airway patency. The cartilaginous and bony components are both susceptible to fracture. Nasal fractures are one of the most common facial injuries, occurring across a broad spectrum of age groups. Inadequate acute injury treatment can lead to persistent airway obstruction and nasal deformities that are subsequently more difficult to correct. Herein we discuss common presentations of nasal fractures, classifications, and options for treatment.

Synechia Formation after Endoscopic Sinus Surgery and Middle Turbinate Medialization with and without FloSeal

The aim of this study was to determine the incidence, outcomes, and risk factors for synechia formation after endoscopic sinus surgery (ESS) and middle turbinate medialization with and without FloSeal. A retrospective review was performed of patients who underwent primary ESS with middle turbinate medialization, with or without the placement of FloSeal. Medialization was performed with the placement of an absorbable conchopexy suture and silastic splint. Operative variables and outcomes were analyzed to identify risk factors for synechia formation. One hundred thirty-five patients underwent medialization alone and 37 patients underwent medialization with placement of FloSeal. Overall, synechia formation was noted in 16 patients (9.3%). A statistically significant higher incidence of synechia formation was noted in patients who underwent middle turbinate medialization with the placement of FloSeal versus medialization alone (18.9% versus 6.7%). The incidences of intraoperative complications (6.2% versus 4.7%) and postoperative complications (6.2% versus 7%) were similar between patients with and without synechia, respectively. Patients experiencing synechia, however, underwent a statistically significant higher rate of revision procedures (25% versus 5.1%). Despite adequate prevention with middle turbinate medialization, synechia formation after ESS may result in higher rates of revision procedures. The placement of FloSeal in conjunction with middle turbinate medialization may result in a higher incidence of synechia formation.

The Use of Silastic Nasal Splints in the Treatment of Chronic Epistaxis and Nasal Septal Ulceration

Some cases of epistaxis are chronic and resistant to treatment. We describe a novel method of treating persistent epistaxis with Silastic splints. This procedure is simple to perform and reverse, and it is much better tolerated than is total obstruction of the nostrils (Young's procedure). In addition, the presence of the splints reduces the likelihood of digital trauma, which can prevent healing. We describe the case of a 43-year-old man with a 5-year history of persistent epistaxis who was successfully treated with this procedure.

Nasal packing after routine nasal surgery—is it justified?

Ninety-five patients undergoing routine nasal surgery were enrolled into a randomized, prospective trial to investigate the efficacy and morbidity of nasal packing. The patients were randomized to receive a bismuth iodoform paraffin paste (BIPP) pack, a Telfa pack or no pack. Patients for septal surgery were randomized between the BIPP and Telfa groups only. They were independently randomized to receive or not receive, a silastic nasal splint for the first post-operative week. Post-operative pain levels were analysed using a visual analogue scale. Mean pain scores were increased 50 per cent by the use of nasal packs and pack removal, particularly BIPP which, was a most painful event (p < 0.001). Reactionary haemorrhage occurred in only two patients (2.1 per cent), both of whom had packs in situ. Vestibulitis was unique to the patients with a silastic splint, who were packed with BIPP, occurring in 21 per cent of them. Similarly septal perforation was unique to this group. There was no significant difference in the incidence of adhesions between the groups which received packs and those who did not. Routine nasal packing, especially with BIPP, would seen difficult to justify in view of the increased pain levels and increased complications which occur without any demonstrable benefit in the majority of patients. Therefore packing should be reserved for cases where there is concern about persistent haemorrhage. In these cases Telfa would be preferable to BIPP.

Intranasal adhesions which recur despite splinting: an ominous sign?

Intranasal adhesions are a common complication following nasal surgery. They may be prevented by the use of silastic splints, which are also a very effective treatment for established lesions. We report a patient where intranasal adhesions rapidly recurred despite the use of splints, who was found to be suffering from Wegener's granulomatosis.

Oviductal damage and the effect of estradiol.

Predictable and reproducible epithelial damage can be created by prolonged splinting of the oviduct. Splinting is associated with the flattening of the mucosal folds, pressure atrophy and deciliation of the epithelium. To overcome this detrimental effect, a silastic splint releasing 3 micrograms/day of estradiol has been compared to an inert splint in rabbits. Scanning electron microscopic observations demonstrated a lesser mucosal damage and reciliation with the steroid-releasing splint.

The importance of mucous membrane graft cryosurgery, silastic splints in nasal surgery

This study starts with a historical review of Septal Surgery. A Septoplasty Procedure carried out to improve the function of nose, using Silastic Splints, cryosurgery of the turbinates and grafting the raw areas of the septal flaps with mucous membrane taken from oral cheek mucosa in 66 cases.

THE SURGICAL TREATMENT OF RETROCAVAL URETER

Ureteric obstruction resulting from retrocaval ureter may be due to either compression of the ureter by the vena cava or stenosis of the postcaval segment. If obstruction is due to stenosis, the commonly described operation of division and anastomosis through the proximal dilated ureter or pelvis, after repositioning of the ureter, is likely to fail, as is division of the vena cava itself. Excision of the postcaval segment with anastomosis of the spatulated ureter over a Silastic splint is therefore recommended. Three case histories of patients with retrocaval ureter treated surgically are presented and support this view.

Renal transplantation in the rat. I. Studies concerning the ureteral anastomosis with special reference to the end-to-end technique.

End-to-end anastomosis of the rat ureter over an in-dwelling silastic splint gives good primary results and a low frequency of complications. This technique has been used when reconstructing the ureter in situ and in renal transplantation.
