A Novel Classification System and Surgical Strategies of First Branchial Cleft Anomalies.

OBJECTIVE: To define a novel classification of first branchial cleft anomalies (FBCAs) based on the relationship between lesions and the facial nerve in terms of radiographic imaging findings and to introduce the corresponding surgical managements. METHODS: The clinical data were retrospectively reviewed. Novel classification was proposed according to the head-neck MRI findings and surgical records. FBCAs limited in the cartilaginous segment of external auditory canal (EAC) or superficial parotid gland capsule were classified as type A. Lesions close to the FN and(or) involved into the parotid gland with no scar formation and no previous parotidectomy were classified as type B. FBCAs adhered to the FN and(or) invaded the parotid gland with scar formation due to previous surgery were classified as type C. Appropriate surgery approaches was also described, which was correlated with classification. RESULTS: Fifty-one patients were included, and one patient suffered from bilateral lesions. Thirty-one, twelve, and nine lesions were classified as type A, type B, and type C FBCAs, respectively. One type A patient (1.92%) suffered from recurrence during follow-up. Temporary facial palsy (House-Brackmann II) was identified in 2 type C patients (3.85%) after surgery and recovered to normal within 2 months. One type B patient (1.92%) suffered from facial paralysis due to the FN injury and underwent facial nerve graft simultaneously. No patients with type C complained of hearing loss postoperatively. CONCLUSION: This novel classification clearly illustrates definitely relationship between lesion and the facial nerve and appropriate surgical strategies were proposed based on the novel classification.

Vallecular cyst causing sleep-disordered breathing in an older child.

Consensus-based recommendations are needed to better guide paediatric otolaryngologists in providing standardised care to children with sleep-disordered breathing (SDB). Here we present a unique case of vallecular cyst found during SDB workup in a patient in their middle childhood (6-12 years old). While the patient underwent successful cyst resection, he was noted to have a suspected recurrence 6 months later. Immediately prior to revision excision, repeat awake flexible fibre-optic laryngoscopy revealed complete resolution of the suspected recurrence. This case underscores the significance of performing a complete upper airway examination, including endoscopic examination, to identify structural and anatomical lesions in older children with SDB.

Reconstruction for Salvage Laryngectomy With Limited Pharyngectomy.

Importance: Closure technique for optimization of postoperative and functional outcomes following salvage laryngectomy remains an area of debate among head and neck surgeons. Objective: To investigate the association of salvage laryngectomy closure technique with early postoperative and functional outcomes. Design, Setting, and Participants: This retrospective cohort study included patients from 17 academic, tertiary care centers who underwent total laryngectomy with no or limited pharyngectomy after completing a course of definitive radiotherapy or chemoradiotherapy with curative intent between January 2011 and December 2016. Patients with defects not amenable to primary closure were excluded. Data were analyzed from February 14, 2021, to January 29, 2024. Exposures: Total laryngectomy with and without limited pharyngectomy, reconstructed by primary mucosal closure (PC), regional closure (RC), or free tissue transfer (FTT). Main Outcomes and Measures: Patients were stratified on the basis of the pharyngeal closure technique. Perioperative and long-term functional outcomes were evaluated with bivariate analyses. A multivariable regression model adjusted for historical risk factors for pharyngocutaneous fistula (PCF) was used to assess risk associated with closure technique. Relative risks (RRs) with 95% CIs were determined. Results: The study included 309 patients (256 [82.8%] male; mean age, 64.7 [range, 58.0-72.0] years). Defects were reconstructed as follows: FTT (161 patients [52.1%]), RC (64 [20.7%]), and PC (84 [27.2%]). A PCF was noted in 36 of 161 patients in the FTT group (22.4%), 25 of 64 in the RC group (39.1%), and 29 of 84 in the PC group (34.5%). On multivariable analysis, patients undergoing PC or RC had a higher risk of PCF compared with those undergoing FTT (PC: RR, 2.2 [95% CI, 1.1-4.4]; RC: RR, 2.5 [95% CI, 1.3-4.8]). Undergoing FTT was associated with a clinically meaningful reduction in risk of PCF (RR, 0.6; 95% CI, 0.4-0.9; number needed to treat, 7). Subgroup analysis comparing inset techniques for the RC group showed a higher risk of PCF associated with PC (RR, 1.8; 95% CI, 1.1-3.0) and predominately pectoralis myofascial flap with onlay technique (RR, 1.9; 95% CI, 1.2-3.2), but there was no association of pectoralis myocutaneous flap with cutaneous paddle interposition with PCF (RR, 1.2; 95% CI, 0.5-2.8) compared with FTT with cutaneous inset. There were no clinically significant differences in functional outcomes between the groups. Conclusion and Relevance: In this study of patients with limited pharyngeal defects, interpositional fasciocutaneous closure technique was associated with reduced risk of PCF in the salvage setting, which is most commonly achieved by FTT in academic practices. Closure technique was not associated with functional outcomes at 1 and 2 years postoperatively.

Impact of stapler versus manual closure techniques on pharyngocutaneous fistula development post-total laryngectomy: A systematic review and meta-analysis.

Pharyngocutaneous fistula (PCF) is a major complication after total laryngectomy, with significant morbidity and mortality. Whether mechanical stapler closure of the pharynx reduces fistula rates compared to hand-sewn techniques remains unclear. We conducted an updated systematic review and meta-analysis to clarify this question. Five databases were systematically searched from inception through November 2023 for studies comparing stapler versus suture closure for fistula outcomes after laryngectomy. Odds ratios (OR) were pooled using random-effects models and fixed-effects models. Subgroup and sensitivity analyses were performed. Risk of bias was appraised using NHLBI tools. Nine studies with 803 patients were included. Mechanical closure significantly reduced fistula incidence versus suture closure (OR = 0.57, 95% CI 0.34-0.95, p = 0.03). Subgroup analysis found that stapling's protective effect varied by patient age, country/region, linear stapler size and female percentage. Stapling reduced fistula odds by 80% in the Turkey subgroup (OR = 0.20, 95% CI 0.09-0.50) but showed no benefit in other regions. Patients <60 years showed an 84% fistula reduction with stapling (OR = 0.17, 95% CI 0.06-0.45), whereas older subgroups did not. Linear stapler size of 60 mm significantly reduced fistula occurrence while 75 mm did not. There was no evidence that low female percentage mitigated stapling benefits. Mechanical stapler closure after total laryngectomy meaningfully reduces the likelihood of postoperative PCF formation compared to hand-sewn closure, especially for patients younger than 60 years old. The absolute risk reduction supports its utility to prevent this complication.

Surgical Management of a Traumatic Retropharyngeal Hematoma in a Patient on Dual Antiplatelet Therapy: A Case Report.

The authors present a case report of a 73-year-old male on dual antiplatelet therapy with a retropharyngeal hematoma after a motor vehicle accident. We highlight the clinical, radiographic manifestations, and surgical management of retropharyngeal hematomas, especially on an initially asymptomatic patient. Additionally, we demonstrate the importance of establishing a secure airway early on, and multidisciplinary collaboration to maximize patient outcomes.

Vascularized Tissue to Reduce Fistula After Salvage Total Laryngectomy: A Network Meta-analysis.

OBJECTIVE: Salvage laryngectomy is more predisposed to complications than primary operations, with pharyngocutaneous fistula (PCF) being among the most challenging to manage. Vascularized flaps are increasingly employed during salvage laryngectomy, with a previous review finding a PCF incidence of 31.2% and 22.2% after primary and flap-assisted closure respectively. We aim to better define the role of vascularized flaps after salvage laryngectomy by performing an updated review comparing the rate of PCF in those undergoing primary or vascularized flap-assisted closure. DATA SOURCES: Pubmed/Medline, CINAHL, and CENTRAL. REVIEW METHODS: An updated literature review was conducted of English language literature from 2003 to 2023. A random effects and network meta-analysis of odds ratios (OR) and pooled proportions were conducted. RESULTS: Literature search found 31 studies, including seven from the previous review. Overall random effects pooled PCF rate was 25% (95% CI 0.21; 0.30, I2 = 72%, p = <0.01), whereas incidence in primary closure was 37% (95% CI 0.32; 0.43, I2 = 60%, p = <0.01) and 19% (95% CI 0.12; 0.20, I2 = 47%, p = <0.01) after flap closure. Pooled OR was 0.39 (95% CI 0.28; 0.55, I2 = 36%, p = 0.04) in favor of vascularized tissues. The number needed to treat was 6.5. The rate of PCF was lower after free and pedicled flaps, and on-lay and patch closure compared to primary closure techniques. Network meta-analysis found all combinations of closure techniques and vascularized tissue were superior to primary closure. CONCLUSION: The updated analysis has demonstrated a widening in the rates of PCF between primary and vascularized flap-assisted closure. Surgeons should strongly consider the use of free or pedicled flaps in any salvage laryngectomy procedure. Laryngoscope, 134:2991-3002, 2024.

Management of Enlarging Tracheoesophageal Fistula with Voice Prosthesis in Laryngectomized Patients.

Management of Enlarging tracheoesophageal fistula (TEF) with Voice Prosthesis in Laryngectomized Head and Neck Cancer Patients. OBJECTIVES: An enlarging TEF following voice prosthesis placement impacts patient quality of life, risks airway compromise, and can lead to aspiration pneumonia. Pharyngoesophageal strictures have previously been reported to be associated with TEF enlargement and leakage. We describe a series of patients with enlarging TEFs after Tracheoesophageal puncture (TEP) for voice prosthesis who required pharyngoesophageal reconstruction. METHODS: Retrospective case series of laryngectomized H&N cancer patients with primary or secondary TEP who underwent surgical management for enlarging TEF site between 6/2016-11/2022. RESULTS: Eight patients were included. The mean age was 62.8 years old. Seven patients had a history of hypothyroidism. Of seven with prior H&N radiation history, two had both historical and adjuvant radiation. Two of the eight TEPs were placed secondarily. Mean time from TEP to enlarging TEF diagnosis was 891.3 days. Radial forearm-free flaps were used in five patients. Six had stenosis proximal to the TEF whereas one had distal stenosis and one had no evidence of stenosis. Mean length of stay was 12.3 days. Mean follow-up was 400.4 days. Two required a second free flap for persistent fistula. CONCLUSION: Surgical reconstruction of enlarging TEFs due to TEP/VP placement is effective in combination with addressing underlying pharyngeal/esophageal stenosis contributing to TEF enlargement and leakage. Radial forearm-free flaps have the additional benefit of a long vascular pedicle to access more distant and less-irradiated recipient vessels. Many fistulae are resolved after the first flap reconstruction, but some may require subsequent reconstruction in case of failure. LEVEL OF EVIDENCE: 4 Laryngoscope, 134:198-206, 2024.

Partial pharyngolaryngectomy with free flap for an unusual pharyngeal stenosis: surgical experience and literature review.

This report describes the case of a middle-aged man who attempted suicide, which resulted in laryngeal webbing and pharyngeal stenosis. The patient was compromised at the level of respiration, necessitating a tracheostomy. Alimentation was also affected, and feeding was done through a gastrostomy tube. Unfortunately, the fibrous tissues were resistant to dilatation and laser treatment. Hence, he underwent a modified partial horizontal supraglottic laryngectomy (PHSL) and pharyngectomy to excise all of the fibrous tissues formed after the incident. The resulting defect was closed with a radial forearm flap (RFF), which is an innovative means of reconstruction after PHSL. The postoperative results were satisfactory. The patient could achieve full oral intake without aspiration at 10 days and the cannula was removed at 3 weeks. This surgical technique could be applied in supraglottic cancers with extension to the pharynx, with repair of the defect by RFF, thus preserving the function of the larynx.

A review of pharyngocutaneous fistula management in head and neck malignancies.

Pharyngocutaneous fistula is a serious complication after head and neck reconstruction and concurrent chemoradiotherapy, yet no consensus or practical protocols regarding the surgical timing and specific procedures could be found in the current literature. The authors aimed to review their clinical experience in surgical management and develop an algorithmic approach accordingly. A retrospective review of all hypopharyngeal cancer patients who developed pharyngocutaneous fistula during 2017 to 2021 at E-Da Hospital was conducted. Seventeen patients developed pharyngocutaneous fistula in all 321 pharyngeal cancer admissions during this period. Three patients received interventions at acute stage (≤2 weeks), with two direct repairs Three patients received interventions at acute stage (≤2 weeks), with two direct repairs and one regional flap coverage then negative pressure wound therapy. Nine received interventions at subacute stages (2 weeks to 3 months), with 4 resolved after debridement and direct repair yet another 4 underwent regional flap reconstruction and 1 free flap reconstruction. Five chronic fistula (>3 months) received secondary reconstructions utilizing a double-layered repair of local turn-over flaps for the internal mucosal opening and another flap harvest (four regional flaps and one free flap) to cover the outer skin defect. All patients after the palliative surgery achieved complete remission of fistula at follow follow-up. Different conservative and surgical approaches should be adopted according to the acute, subacute, and chronic stages of pharyngocutaneous fistula after palliative head and neck reconstructions.

Transnasal negative pressure therapy for accelerating healing and improving the prognosis of pharyngocutaneous fistula.

BACKGROUND: Pharyngocutaneous fistula (PCF) is one of the most common complications of total laryngectomy. This study is to investigate the efficacy of a novel platform called transnasal negative pressure therapy (TNPT) in the management of PCF. METHODS: We retrospectively reviewed 47 patients who underwent total laryngectomy between April 2015 and February 2021 and developed PCF in our hospital. We focused on the healing rate, dressing change frequency, and healing time between the TNPT and non-TNPT groups. The 2 years overall survival (OS) was compared through the log-rank test. RESULTS: There were 18 patients in the TNPT group and 29 in the non-TNPT group. There was no significant between-group difference in the healing rate (chi-square test). However, the frequency of dressing changes was significantly lower (p < 0.001) and the healing time was significantly shorter (p = 0.0194) in the TNPT group than in the non-TNPT group. The 2-year OS rate was significantly higher in the TNPT group (p = 0.0473, log-rank test). CONCLUSION: TNPT promoted wound healing after surgery for PCF and improved the 2-year OS rate. This tool is worthy of clinical application and promotion.

Use of contrast-enhanced ultrasound in preoperative planning before resection of a second branchial cleft fistula.

In the head and neck area, a large proportion of clinically relevant fistulas occur in childhood. The present case describes the use of contrast enhanced ultrasound with intraductal administration of the contrast medium for preoperative visualization of the fistula duct in the case of a second brachial cleft fistula. This provided the surgeon with important additional information, such as the detailed course of the fistula and its relation to the large vessels of the neck. The method can help to improve surgical planning, reduce radiation exposure and to avoid imaging under general anesthesia, especially in children.

Perioperative Factors Aggravating Pharyngocutaneous Fistula After Total Laryngectomy: A Single-Center Retrospective Analysis Using the Clavien-Dindo Classification.

BACKGROUND: Pharyngocutaneous fistula formation represents a major postoperative complication following total laryngectomy. We aimed to investigate the risk factors for pharyngocutaneous fistula development after total laryngectomy and to identify factors that lead to severe cases of pharyngocutaneous fistula. METHODS: Patients who underwent total laryngectomy between January 2013 and February 2021 were included in the study and were divided into 2 groups: Those with and without pharyngocutaneous fistula. The severity of pharyngocutaneous fistula was graded using the Clavien-Dindo classification. RESULTS: Patients with pharyngocutaneous fistula experienced longer operative time, greater intraoperative blood loss, greater decrease in perioperative hemoglobin level, and longer postoperative hospitalization. Unlike in lower-severity cases, patients with grade IIIb pharyngocutaneous fistula underwent preoperative radiotherapy or chemoradiotherapy; preoperative treatment was thus a risk factor for higher severity of pharyngocutaneous fistula (odds ratio, 35; P = 0.004). CONCLUSION: Salvage laryngectomy was found to be a predictor of severe pharyngocutaneous fistula development. Prolonged operative time, increased intraoperative blood loss, and decreased postoperative hemoglobin level were found to be predictors of postlaryngectomy pharyngocutaneous fistula formation.

Pharyngeal Reconstruction Methods to Reduce the Risk of Pharyngocutaneous Fistula After Primary Total Laryngectomy: A Scoping Review.

INTRODUCTION: The most common early postoperative complication after total laryngectomy (TL) is pharyngocutaneous fistula (PCF). Rates of PCF are higher in patients who undergo salvage TL compared with primary TL. Published meta-analyses include heterogeneous studies making the conclusions difficult to interpret. The objectives of this scoping review were to explore the reconstructive techniques potentially available for primary TL and to clarify which could be the best technique for each clinical scenario. METHODS: A list of available reconstructive techniques for primary TL was built and the potential comparisons between techniques were identified. A PubMed literature search was performed from inception to August 2022. Only case-control, comparative cohort, or randomized controlled trial (RCT) studies were included. RESULTS: A meta-analysis of seven original studies showed a PCF risk difference (RD) of 14% (95% CI 8-20%) favoring stapler closure over manual suture. In a meta-analysis of 12 studies, we could not find statistically significant differences in PCF risk between primary vertical suture and T-shaped suture. Evidence for other pharyngeal closure alternatives is scarce. CONCLUSION: We could not identify differences in the rate of PCF between continuous and T-shape suture configuration. Stapler closure seems to be followed by a lower rate of PCF than manual suture in those patients that are good candidates for this technique.

New classification and surgical strategy for work type I congenital first branchial cleft anomalies in children.

PURPOSE: To investigate the anatomical relationships between the structures adjacent to the cartilaginous portion of the ear canal in children with Work type I congenital branchial cleft anomalies (CFBCAs) and to develop new classifications and surgical strategies. METHODS: Retrospective analysis was performed on 50 children with Work type I CFBCAs admitted between December 2018 and December 2022. RESULTS: Among the 50 children, total parotidectomy was performed on 49 sides. In 44 cases (88%), the main body of the lesion was closely associated with the cartilage of the inferior ear canal wall. Among these cases, the lesions in 40 cases occurred within the space enclosed by the dorsal inferior wall cartilage, mastoid process, and parotid gland, while in the remaining four cases, the lesions were located between the anterior inferior wall cartilage and parotid gland. Based on the preoperative imaging observations, clinical manifestations, and intraoperative findings, the cases were classified into 6 subtypes (a to f) including 21 cases (42%) of Type Ia (inferior wall of EAC), 7 cases (14%) of Type Ib (bottom wall of EAC), 12 cases (24%) of Type Ic (posterior-inferior wall of EAC), 4 cases (8%) of Type Id (anterior-inferior wall of EAC), 4 cases (8%) of Type Ie (anterior ear wall of EAC), and 2 cases (4%) of Type If (isolated from parotid). CONCLUSION: Surgical intervention is the only treatment for first branchial cleft anomalies and a comprehensive understanding of the classifications will help with the precise localisation and excision of the lesions.

Pedicled thoracoacromial artery compound flaps for circumferential hypopharyngeal reconstruction.

BACKGROUND: Total laryngeal and hypopharyngeal resection remained to be the mainly treatment option for advanced hypopharyngeal cancer, which resulted in complicated reconstructive challenge for circumferential hypopharyngeal defect. The pedicled thoracoacromial artery compound flaps included Thoracoacromial artery perforator (TAAP) flap and pectoralis major myocutaneous (PMMC) flap. This study is to evaluate the clinical application of the pedicled thoracoacromial artery compound flaps for circumferential hypopharyngeal reconstruction. METHODS: From May 2021 to April 2022, four hypopharyngeal cancer patients with circumferential hypopharyngeal defects were reconstructed by the pedicled thoracoacromial artery compound flaps. All patients were males. Patient age ranged from 35 to 62 years (average, 50 years). The Shoulder function were evaluated by SPADI. The average follow-up was 10.25 months (range from 4 to 18 months). RESULTS: All of the pedicled thoracoacromial artery compound flaps in our study survived. The defect length between tongue base and cervical esophagus ranged from 8 to 10 cm after total laryngeal and hypopharyngeal resection. The TAAP flap size ranged from 6 × 7 cm to 7 × 10 cm, and the PMMC flap size ranged from 6 × 7 cm to 9 × 12 cm. The pedicle length of TAAP and PMMC flaps varied, respectively, from 5 to 8 cm (mean 6.5 cm) and 7 cm to 11 cm (mean 8.75 cm). The mean time of TAAP and PMMC flaps harvest was, respectively, 82 min and 39 min. All patients were able to resume soft diet in the fourth week of postoperation, but one patient was operated by gastrostomy in the second month of postoperation because of pharyngeal cavity stenosis, and the patient successfully resumed oral soft diet by endoscopic balloon dilation after postoperation radiotherapy. All patients have resumed oral feeding at last. There were mild dysfunction for our patients according to SPADI during the mid-long follow-up. CONCLUSIONS: The pedicled thoracoacromial artery compound flaps have stable blood supply and provide adequate muscle coverage for greater protection during radiotherapy, and the microsurgical skills have no requirement. Therefore, the compound flaps provide a good choice for the reconstruction of circumferential hypopharyngeal defect, especially in the aged or patients with comorbidities who are not able to tolerate prolonged surgery.

Collaural fistula: Our experience.

Branchial cleft anomalies are congenital, arising from the first to the fourth pharyngeal clefts. The most common is a second arch anomaly. As it is congenital, it presents at birth though may become symptomatic later. The spectrum of anomalies includes sinus, cyst, or fistula formation or a combination of these. Here we present a case series based on first cleft anomalies. The principles of management include early diagnosis, excision of any fistulous tract, and prevention of injury to the facial nerve.

Effect of possible risk factors for pharyngocutaneous fistula after total laryngectomy of laryngeal carcinomas and surgical wound infection: A meta-analysis.

A meta-analysis study to assess the effect of possible risk factors for pharyngocutaneous fistula (PCF) after total laryngectomy of laryngeal carcinoma. A comprehensive literature examination till January 2023 was implemented and 1794 linked studies were appraised. The picked studies contained 3140 subjects with total laryngectomy of laryngeal carcinomas in the picked studies' baseline, 760 of them were PCF, and 2380 were no PCF. Odds ratio (OR) in addition to 95% confidence intervals (CIs) were used to calculate the consequence of possible risk factors for PCF after total laryngectomy of laryngeal carcinomas and surgical wound infection after total laryngectomy of laryngeal carcinoma by the dichotomous and continuous styles and a fixed or random model. The PCF had a significantly higher surgical wound infection (OR, 6.34; 95% CI, 1.89-21.27, P = .003) compared with the no PCF in total laryngectomy of laryngeal carcinomas. The smoking (OR, 1.73; 95% CI, 1.15-2.61, P = .008), and preoperative radiation (OR, 1.90; 95% CI, 1.37-2.65, P < .001) had significantly higher PCF as a risk factor in total laryngectomy of laryngeal carcinomas. The preoperative radiation had a significantly lower spontaneous PCF closure (OR, 0.33; 95% CI, 0.14-0.79, P = .01) compared with the no preoperative radiation in total laryngectomy of laryngeal carcinomas. However, the neck dissection (OR, 1.34; 95% CI, 0.75-2.38, P = .32), and alcohol intake (OR, 1.95; 95% CI, 0.76-5.05, P = .17), had no significant effect on PCF in total laryngectomy of the PCF had a significantly higher surgical wound infection, and preoperative radiation had a significantly lower spontaneous PCF closure in total laryngectomy of laryngeal carcinomas. Smoking and preoperative radiation were shown to be risk factors for PCF, however, neck dissection and alcohol intake were not shown to be risk factors for PCF in total laryngectomy of laryngeal carcinomas. Although precautions should be taken when commerce with the consequences because some of the picked studies for this meta-analysis was with low sample sizes.

Delayed Pharyngocutaneous Fistula After Total Laryngectomy Caused by an Anterior Cervical Spine plate.

Pharyngocutaneous fistula (PCF) caused by a previous anterior cervical spine fixation plate more than a decade ago has not been reported yet. A 70-year-old man with dysphagia was diagnosed as supraglottic cancer. After partial laryngectomy and concurrent chemoradiation, due to increasing arytenoid lesion, total laryngectomy was followed. Pharyngocutaneous fistula occurred but resolved spontaneously. However, retropharyngeal granulation tissue emerging from the anterior cervical spine fixation plate caused delayed PCF. Dysphagia and PCF resolved after fixation plate removal.
