Pyriform sinus cyst is a rare disease. This disease can be found by chance or appear as lymph nodes with cancer, infections, shortness of breath, or airway compromise, and can be an unusual cause of dysphonia. This paper presents a case of a pyriform sinus cyst in the pharyngeal wall of the left pyriform sinus, which presented as neck discomfort in a 63-year-old female. The plan was to remove this cyst with a transoral CO₂ laser because a CO₂ laser is a useful tool for removing cysts without bleeding and consuming time. The excision was performed successfully. Transoral laser pyriform sinus cyst excision is a simple, safe, and effective method for the treatment of pyriform sinus cysts. This procedure is likely to be used as a selective treatment when managing this condition.

Pyriform sinus fistula is a rare anomaly arising from 3rd or 4th branchial apparatus and has been recognized as one cause of acute suppurative thyroiditis or acute deep neck infection. Pyriform sinus fistula must be considered when a clinician is encountered recurrent left lower neck abscess and a history of repeated incision and drainage. The confirmation of the diagnosis is made when the fistula tract is identified on a barium swallow study and when the internal orifice of the fistula is found at the apex of pyriform sinus on laryngoscopic examination. A complete excision of the fistula tract has been proposed as a treatment of choice. However, in some cases it is very difficult to resect the tract completely because of severe inflammation and repeated drainage procedure. We present three cases of pyriform sinus fistula which are successfully treated by laryngomicroscopic chemocauterization using synthetic fibrin and $AgNO_3$.

Pyriform sinus perforation is a rare complication of endotracheal intubation. It most commonly occurs at the hands of the less experienced physician in emergency situations. It can occur after traumatic intubation and is potentially lethal. The site most commonly perforated is the pharynx, posterior to the cricopharyngeal muscle; the second most common site is the pyriform sinus. We report a case of pyriform sinus perforation after endotracheal intubation, which was successfully treated with primary closure.

Hypopharyngeal carcinoma is an aggressive malignancy that usually presents at a late stage, thereby resulting in an overall poor prognosis fir these unfortunate patients. The most effective treatment of pyriform sinus carcinoma combines surgery and radiation. Total laryngopharyngectomy is necessary in advanced tumors, but may not be appropriate in limited lesions. Therefore several procedure for partial laryngopharyngectomy have been proposed. Supracricoid hemilaryngopharyngectomy is the one of these procedure. This report presents one case of supracricoid hemilaryngopharyngectomy in a patient with pyriform sinus medial wall cancer and analyses aerodynamic study before and after operation.

We describe a case of venous malformation of pyriform sinus in 63 year-old patient, discovered incidentally. Venous malformation are the most common vascular malformations to arise in the head and neck. However venous malformation of the hypopharynx in the adult papulation are rare. The author performed successfully ethanol sclerotherapy for venous malformation of pyriform sinus, so we present the case with a review of the related literatures.

Acute suppurative thyroiditis is rare, infectious thyroid disorder because the thyroid gland is resistant to infection. We report a 26-year-old man with acute suppurative thyroiditis due to a pyriform sinus fistula. He presented with anterior neck swelling and tenderness for 2 weeks. Antibiotic treatment failed to improve his symptoms and signs. Diagnosis was made by bariums studies, computed tomography scan and endoscopic examination. The pyriform siuns fistula was successfully treated by chemical cauterization, partial thyroidectomy and ligation of fistula tract.

Osteochondroma, known as osteocartilaginous exostosis, is most common benign bone tumor. The pyriform sinus are extremely rare involved, and there are a few cases reported. Most patients complain of foreign body sensation, and histologic diagnosis can confirm the disease. Treatment is by surgical excision. This should give complete resolution and there were rare recurrences with good prognosis. We experienced a osteochondroma of the priform sinus presenting as a submucosal mass. We report the case with a review of literatures.

경식도 초음파는 심장수술에서 비교적 안전하게 수술 중 심장의 기능 및 수술 결과를 평가할 수 있어 그 이용이 일반화되고 있으며, 경식도 초음파 관련 합병증은 드물지만 하인두 손상이나 식도 천공 등 위험한 합병증이 생길 수 있다. 폐부종을 동반한 심근경색으로 진단받은 77세 남자환자에서 심폐 바이패스를 사용하 않는 관상동맥우회술 시행 후, 수술 중 경식도 초음파 시술과 관련되어 발생한 것으로 추정되는 pyriform sinus 천공 및 이에 동반된 경부 심부감염을 경험하여 보고하는 바이다.

The pyriform sinus fistula can cause a recurrent abscess in the neck and the current treatment of choice involves complete excision of the sinus tract. But, because of excisional difficult, chemical cautery has been intermittently used as a successful substitute. Recently we experienced a case of pyriform sinus fistula of 9 year-old female who was successfully treated with chemocauterization with trichloroacetic acid(TCA) and ligation of the internal opening of the fistula tract on suspension laryngoscopy. So we report this rate case with review of literatures.

A 49-year-old male patient with a carcinoma of the right pyriform sinus had a whole-body bone scan and gamma camera based F-18 FDG-PET for staging. Tc-99m MDP bone scan depicted diffuse increased uptake in the left femur due to chronic osteomyelitis but no skeletal metastasis. F-18-FDG-PET revealed increased focal bone uptake and uptake in the draining sinus due to chronic osteomyelitis in addition to visualization of the right pyriform sinus carcinoma and right neck nodal uptake. Fluorine-18 fluorodeoxyglucose-positron emission tomography is significantly more accurate than the bone scan in pinpointing chronic osteomyelitis focus and draining soft tissue infection.
