Adenoid cystic carcinoma of the nasal septum is extremely rare. We present the case of a 56-year- old male who complained of nasal bleeding and nasal obstruction for 1 month. A mass arising from nasal septum was found by endoscope. The tumor was removed under lateral rhinotomy and histopathologic examination revealed adenoid cystic carcinoma with cribriform pattern. He then had postoperative radiotherapy. No recurrence was noticed after 1 year of follow-up. Despite its rarity, adenoid cystic carcinoma should be taken into consideration in the differential diagnosis of nasal tumor.

  • Rhinoplasty and Septoplasty
    Rhinoplasty and Septoplasty Surgically altering the nose is a common plastic surgery procedure that often has a profound impact on a patient’s life. In some cases this procedure is required to alter the internal anatomy of the nose in order to address functional breathing problems. In others a patient may desire to change the appearance of their nose. Rhinoplasty alters the external appearance of the nose, improving its shape and balance with the face. Frequently a combination of internal and external alterations are performed simultaneously. Functional Problems Airway obstruction is the most common functional nasal problem. It may be caused by either congenital or post- traumatic deformity of the nasal septum. Enlargement of the turbinates may also occur, creating an airway obstruction. All of these changes can exacerbate existing sinus problems. Cosmetic Deformity Some cosmetic deformities of the nose are post traumatic, while others are congenital. Both can be addressed similarly by surgically altering the underlying bony and cartilaginous framework of the nose. The Procedure Septoplasty and rhinoplasty are generally done on an outpatient basis and require either general anesthesia or sedation with a local. Airway problems are treated by removing or reshaping the septal cartilage. Some cases require a reduction in the size of the turbinates. Changes to the shape of the nose are accomplished by reshaping the bone and cartilage framework of the nose. In most cases the incisions can be located inside the nose resulting in no visible scars. Frequently used post-operative measures include splinting, taping and nasal packing. The Results Rhinoplasty can have a substantial effect on a person’s appearance and, ultimately, their general sense of well-being.

  • Deviated Septum the Shape of Your Nasal Cavity Could Be the Cause of Chronic Sinusitis
    Deviated Septum The shape of your nasal cavity could be the cause of chronic sinusitis. The nasal septum is the wall dividing the nasal cavity into halves; it is composed of a central supporting skeleton covered on each side by mucous membrane. The front portion of this natural partition is a firm but bendable structure made mostly of cartilage and is covered by skin that has a substantial supply of blood vessels. The ideal nasal septum is exactly midline, separating the left and right sides of the nose into passageways of equal size. Estimates are that 80 percent of all nasal septums are off-center, a condition that is generally not noticed. A “deviated septum” occurs when the septum is severely shifted away from the midline. The most common symptom from a badly deviated or crooked septum is difficulty breathing through the nose. The symptoms are usually worse on one side, and sometimes actually occur on the side opposite the bend. In some cases the crooked septum can interfere with the drainage of the sinuses, resulting in repeated sinus infections. Septoplasty is the preferred surgical treatment to correct a deviated septum. This procedure is not generally performed on minors, because the cartilaginous septum grows until around age 18. Septal deviations commonly occur due to nasal trauma. A deviated septum may cause one or more of the following: • Blockage of one or both nostrils • Nasal congestion, sometimes one-sided • Frequent nosebleeds • Frequent sinus infections • At times, facial pain, headaches, postnasal drip • Noisy breathing during sleep (in infants and young children) In some cases, a person with a mildly deviated septum has symptoms only when he or she also has a "cold" (an upper respiratory tract infection).

The respiratory infection triggers nasal inflammation that temporarily amplifies any mild airflow problems related to the deviated septum. Once the cold resolves and the nasal inflammation subsides, symptoms of the deviated septum resolve, too. Treatment Surgery may be recommended if the deviated septum is causing troublesome nosebleeds or recurrent sinus infections.

Treatment for nasal cavity or paranasal sinus cancer may include: ● Surgery for Nasal Cavity and Paranasal Sinus Cancers ● Radiation Therapy for Nasal Cavity and Paranasal Sinus Cancers ● Chemotherapy for Nasal Cavity and Paranasal Sinus Cancers ● Targeted Drug Therapy for Nasal Cavity and Paranasal Sinus Cancers ● Immunotherapy for Nasal Cavity and Paranasal Sinus Cancers ● Supportive Treatment for Nasal Cavity and Paranasal Sinus Cancers Common treatment approaches Depending on the stage of the cancer and your general health, different treatment options may be used alone or in combination. In general, surgery is the first treatment for cancers of the nasal cavity and paranasal sinuses.
