Objectives: The objective of this review was to determine the rate and risk factors of paratracheal lymph node (PTLN) involvement during total laryngectomy (TL) or total pharyngolaryngectomy (TPL). In addition, we aimed to assess its prognostic significance in terms of survival and peristomal recurrence.
Methods: A comprehensive electronic search was performed on PubMed, EMBASE, and CENTRAL databases. We searched for studies reporting outcomes of PTLN dissection during radical laryngeal surgery for squamous cell carcinoma of the larynx, hypopharynx or cervical oesophagus.
Results: We included a total of ten studies (838 patients). The overall rate of PTLN dissection positivity was 18.6% (20.7% for primary TL, 8.7% for salvage TL). Random-effects meta-analysis identified T4 stage, N+ stage of the lateral neck, subglottis involvement and primary tumour arising from the hypopharynx or cervical oesophagus as significant risk factors for PTLN involvement.
Conclusions: This meta-analysis allowed to better define the risk of PTLN involvement during TL or TPL, in a bid to guide indication for PTLN dissection. There is a need for further large studies reporting rigorously the outcomes of PTLN dissection in order to establish stronger evidence-based recommendations.

Objectives: This study aims to evaluate the effect of paratracheal lymph node (PTLN) metastasis on survival in patients with advanced laryngeal and hypopharyngeal cancer.
Patients And Methods: Medical records of advanced laryngeal and hypopharyngeal cancers who underwent surgery between May 1995 and June 2008 were assessed and 78 of the patients (63 males, 15 females; mean age 55±11.3 years; range 25 to 76 years) who has PTLN metastasis were included in this study.

Background: There are no specific therapeutic guidelines for thyroid cancers confined to the isthmus. To determine whether isthmic papillary thyroid carcinoma (PTC) can be treated with thyroid isthmusectomy and limited neck dissection, we analyzed factors related to central lymph node (CLN) metastasis in patients with clinically node-negative (cN0), solitary, isthmic PTC.
Methods: We retrospectively reviewed 73 consecutive patients who underwent surgery for solitary isthmic, PTC.
Diagnostic value of CT and MRI in the detection of paratracheal lymph node metastasis.

The presence of paratracheal lymph node (PTLN) metastasis harbours a worse prognosis. Uniform guidelines on PTLN dissection are missing, mainly because of the value of diagnostic techniques for the detection of PTLN metastasis are not clear. This study is performed to identify CT and MRI criteria for detection of PTLN metastasis.

Objectives: To evaluate complications and histopathological results of paratracheal lymph node dissection (PTLND) at laryngectomy after (chemo)radiotherapy.
Design, Setting And Participants: In a retrospective analysis, complications and histopathological results of paratracheal lymph node dissections were analysed in 191 patients with a recurrent or second primary laryngeal or hypopharyngeal carcinoma following radiotherapy with or without chemotherapy.
Main Outcome Measures: The percentage of complications in patients with bilateral, unilateral or without PTLND.
