Clinical features and management analysis of 11 cases of laryngocele / 中华耳鼻咽喉头颈外科杂志

Objective: To summarize clinical features and our experience of the diagnosis and treatment of laryngocele. Methods: Clinical data of 11 laryngocele patients in department of Otorhinolaryngology Head and Neck Surgery of the Second Affiliated Hospital of Shanxi Medical University from January 2012 to December 2021 were retrospectively reviewed, including 9 men and 2 women, aged from 12 to 75 years, with median age of 56 years. Electronic laryngoscope was performed in 10 of all patients, laryngeal CT in 10 and cervical color ultrasound in 5 before operation.All the operations were performed under general anesthesia, and the external cervical approach was used for external and combined laryngocele. The internal laryngocele was resected by low temperature plasma through transoral endoscopy. Patients were followed up regularly after operation to evaluate the effect. Clinical feature, types of lesions, imaging findings, surgical approaches and follow-up results were analyzed through descriptive statistical method. Results: Eleven laryngocele patients were divided into mixed type (n=6), internal type (n=4) and external type (n=1).Nine patients presented with hoarseness or dysphonia, 7 with cervical mass and 1 with airway obstruction. Surgical resections were done through external cervical approach (n=7)or transoral endoscopic approach (n=4). All the operations were successful and no complication occurred. All cases were followed up from 17 to 110 months. No recurrence was encountered. Conclusions: Laryngocele is a rare lesion with atypical clinical presentation. Preoperative imaging including CT scan and electronic laryngoscope is essential to evaluate the location, and extent of the lesion, and to make the surgical plan.Complete surgical excision is required. Surgical resection is the only effective method for the treatment of laryngocele.

Cervicothoracic Thymic Cyst: An Unusual Presentation

Cervicothoracic thymic cysts are rare and difficult to diagnose preoperatively. We report a case of a cervicothoracic thymic cyst presenting as a lateral neck mass and mimicking a laryngocele in a 3-year-old boy and its definitive management.

Laryngocele à propos de 9 cas

La laryngocele est une pathologie rare. elle est definit par la dilatation progressive du saccule larynge. Le diagnostic est suspecte par l'examen clinique; sa prise en charge est encore discutee. nous rapportons une etude retrospective portant sur 9 patients ayant ete suivis et traites pour une laryngocele. La serie a ete colligee sur une periode de 14 ans; allant de 1998 a 2011. Six de nos patients avaient une laryngocele externe; deux patients avaient une laryngocele mixte et un patient avait une laryngocele interne. Une surinfection a ete notee chez trois patients realisant ainsi le tableau de pyolaryngocele. Tous les patients ont eu un examen clinique complet comportant un examen OrL et cervico-facial ainsi qu'un examen larynge au nasofibroscope. La tomodensitometrie cervicale a ete realisee de facon systematique. Huit de nos malades ont ete abordes par voie cervicale permettant une exerese complete du sac. Le recul moyen etait de 38 mois sans recidive. Toute laryngocele decouverte; doit etre traitee afin d'eviter les complications essentiellement locales pouvant mettre en jeu le pronostic vital. Les modalites therapeutiques dependent du type de la laryngocele

Quistes y tumores de la laringe / Cysts and tumors of the larynx

Los quistes de la laringe son lesiones benignas que por lo general se tratan con facilidad. El tratamiento de estos quistes saculares en general se realiza a través de laringoscopia directa. En la clasificación se identifican quistes saculares, ductales, laringoceles se describe la fisiopatalogía y las manifestaciones clínicas.

Schwannoma Mimicking Laryngocele

A schwannoma of the larynx is a rare benign tumor that usually presents as a submucosal mass in the pyriform sinus and the aryepiglottic space, and this type of schwannoma constitutes a diagnostic and therapeutic challenge for otolaryngologists. We present here two cases of supraglottic schwannomas that were misdiagnosed as laryngoceles. Both were excised through a lateral thyrotomy approach without a tracheostomy, and the laryngeal function was successfully maintained. We discuss the clinical and imaging findings and the management of this rare neoplasm with focusing on the differential diagnosis of laryngeal schwannoma and laryngocele. We also review the relevant medical literature.

Two Cases of Jugular Phlebectasia / 대한이비인후과학회지

Anterior or lateral neck mass that appears on straining should be differentiated from laryngocele, jugular phlebectasia and superior mediastinal cysts or masses. The most common cause of aneck masses which that appears on straining is alaryngocele. The jugular phlebectasia may present itself in a similar manner, although it occurs rarely. The cause of the jugular phlebectasia is unclear. The diagnosis is made on a clinical basis and confirmed by the less invasive radiological technique. No treatment is indicated because of its self-limiting, benign condition. However, the surgical removal is needed for cosmetic purposes by a unilateral excision of the jugular vein. We experienced two cases of jugular phlebectasia, one anterior and the other internal. One case of The anterior jugular phlebectasia was successfully treated by surgical excision, and the other case of internal jugular phlebectasia was treated conservatively.

A Case of Bilateral Mixed Type Laryngocele / 대한이비인후과학회지

A laryngocele is an uncommon, air-filled dilatation of the laryngeal saccule or appendix of the laryngeal ventricle with an unclear etiology. This abnormality is generally classified into internal, external, or mixed type depending on their relationship to the thyrohyoid membrane. Many laryngoceles are asymptomatic and are discovered incidentally when radiographs of the neck or endolaryngeal examinations are performed for unrelated symptoms. We have experienced a case of bilateral mixed type laryngocele.

A Case of Bilateral Internal Jugular Phlebectasia / 대한이비인후과학회지

Phlebectasia is an abnormal dilatation of an isolated vein and a rare venous anomaly and is usually asymptomatic. Internal jugular phlebectasia is a localized, nonpulsatile, nontender, compressible, and saccular or fusiform dilatation that enlarges with Valsalva maneuver, sneezing, coughing and straining which increases intrathoracic pressure. Internal jugular phlebectasia predominantly affects young children and its etiology is idiopathic in most cases, but several predisposing factors have been suggested. Although histopathological findings of most cases had no significant abnormality, those of some cases showed elastic dysplasia, focal intimal thickening and muscular defect within the wall of the vein. A swelling in the neck which enlarges with Valsalva maneuver must be differentiated from other diseases. Internal jugular phlebectasia is most likely to be mistaken for laryngocele, superior mediastinal cyst or branchial cleft cyst. Diagnosis should be as non-invasive as possible because no treatment is indicated for this benign self-limiting condition. We present a case of bilateral internal jugular phlebectasia of which diagnosis was made by sonography with doppler technique and neck CT.

Saccular disorders in cancer larynx

Abnormal saccular dilatations like laryngoceles, laryngomucoceles, large dilated saccules, and saccular cysts have been reported to occur secondary to laryngeal tumors. These disorders occurred in 11.5% [15/130] of our cases of cancer larynx. Laryngoceles, large saccules, and saccular cysts were found in 3.1%, 4.6%, and 3.8% of cases respectively. CT proved to be very accurate more than endoscopy in detection of symptomatic or asymptomatic saccular disorders associated with cancer larynx. However both endoscopy and CT are recommended in cases presented with laryngoceles or saccular cysts to rule out any underlying malignancy
